    About this Episode

    Taiwan is a country about half the size of Maine with about 17 times the population of that state. Taiwan sits just over a hundred miles off the coast of mainland China. It’s home to some 23 and a half million humans, roughly half way between Texas and Florida or a few more than live in Romania for the Europeans. Taiwan was connected to mainland China by a land bridge in the Late Pleistocene and human remains have been found dating back to 20,000 to 30,000 years ago. About half a million people on the island nation are aboriginal, or their ancestors are from there. But the population became more and more Chinese in recent centuries.

    Taiwan had not been part of China during the earlier dynastic ages but had been used by dynasties in exile to attack one another and so became a part of the Chinese empire in the 1600s. Taiwan was won by Japan in the late 1800s and held by the Japanese until World War II. During that time, a civil war had raged on the mainland of China with the Republic of China eventually formed as the replacement government for the Qing dynasty following a bloody period of turf battles by warlords and then civil war.

    Taiwan was in martial law from the time the pre-communist government of China retreated there during the exit of the Nationalists from mainland China in the 1940s to the late 1980. During that time, just like the exiled Han dynasty, they orchestrated war from afar. They stopped fighting, much like the Koreans, but have still never signed a peace treaty. And so large parts of the world remained in stalemate. 

    As the years became decades, Taiwan, or the Republic of China as they still call themselves, has always had an unsteady relationship with the People’s Republic of China, or China as most in the US calls them. The Western world recognized the Republic of China and the Soviet and Chines countries recognized the mainland government. US President Richard Nixon visited mainland China in 1972 to re-open relations with the communist government there and relations slowly improved.

    The early 1970s was a time when much of the world still recognized the ruling government of Taiwan as the official Chinese government and there were proxy wars the two continued to fight. The Taiwanese and Chinese still aren’t besties. There are deep scars and propaganda that keep relations from being repaired. 

    Before World War II, the Japanese also invaded Hong Kong. During the occupation there, Morris Chang’s family became displaced and moved to a few cities during his teens before he moved Boston to go to Harvard and then MIT where he did everything to get his PhD except defend his thesis. He then went to work for Sylvania Semiconductor and then Texas Instruments, finally getting his PhD from Stanford in 1964. He became a Vice President at TI and helped build an early semiconductor designer and foundry relationship when TI designed a chip and IBM manufactured it.

    The Premier of Taiwan at the time, Sun Yun-suan, who played a central role in Taiwan’s transformation from an agrarian economy to a large exporter. His biggest win was when to recruit Chang to move to Taiwan and found TSCM, or Taiwan Semiconductor Manufacturing Company. Some of this might sound familiar as it mirrors stories from companies like Samsung in South Korea. In short, Japanese imperialism, democracies versus communists, then rapid economic development as a massive manufacturing powerhouse in large part due to the fact that semiconductor designers were split from semiconductor foundry’s or where chips are actually created. 

    In this case, a former Chinese national was recruited to return as founder and led TSMC for 31 years before he retired in 2018. Chang could see from his time with TI that more and more companies would design chips for their needs and outsource manufacturing. They worked with Texas Instruments, Intel, AMD, NXP, Marvell, MediaTek, ARM, and then the big success when they started to make the Apple chips. The company started down that path in 2011 with the A5 and A6 SoCs for iPhone and iPad on trial runs but picked up steam with the A8 and A9 through A14 and the Intel replacement for the Mac, the M1. They now sit on a half trillion US dollar market cap and are the largest in Taiwan. For perspective, their market cap only trails the GDP of the whole country by a few billion dollars. 

    Nvidia
    TSMC is also a foundry Nvidia uses. As of the time of this writing, Nvidia is the 8th largest semiconductor company in the world. We’ve already covered Broadcom, Qualcomm, Micron, Samsung, and Intel. Nvidia is a fabless semiconductor company and so design chips that vendors like TSMC manufacture. 

    Nvidia was founded by Jensen Huang, Chris Malachowsky, and Curtis Priem in 1993 in Santa Clara, California (although now incorporated in Delaware). Not all who leave the country they were born in due to war or during times of war return. Huang was born in Taiwan and his family moved to the US right around the time Nixon re-established relations with mainland China. Huang then went to grad school at Stanford before he became a CPU designer at AMD and a director at LSI Logic, so had experience as a do-er, a manager, and a manager’s manager. 

    He was joined by Chris Malachowsky and Curtis Priem, who had designed the IBM Professional Graphics Adapter and then the GX graphics chip at Sun.   because they saw this Mac and Windows and Amiga OS graphical interface, they saw the games one could play on machines, and they thought the graphics cards would be the next wave of computing. And so for a long time, Nvidia managed to avoid competition with other chip makers with a focus on graphics. That initially meant gaming and higher end video production but has expanded into much more like parallel programming and even cryptocurrency mining.  

    They were more concerned about the next version of the idea or chip or company and used NV in the naming convention for their files. When it came time to name the company, they looked up words that started with those letters, which of course don’t exist - so instead chose invidia or Nvidia for short, as it’s latin for envy - what everyone who saw those sweet graphics the cards rendered would feel. 

    They raised $20 million in funding and got to work. First with SGS-Thomson Microelectronics in 1994 to manufacture what they were calling a graphical-user interface accelerator that they packaged on a single chip. They worked with Diamond Multimedia Systems to install the chips onto the boards. In 1995 they released NV1. The PCI card was sold as Diamond Edge 3D and came with a 2d/3d graphics core with quadratic texture mapping. Screaming fast and Virtual Fighter from Sega ported to the platform. 

    DirectX had come in 1995. So Nviia released DirectX drivers that supported Direct3D, the api that Microsoft developed to render 3d graphics. This was a time when 3d was on the rise for consoles and desktops. Nvidia timed it perfectly and reaped the rewards when they hit a million sold in the first four months for the RIVA, a 128-bit 3d processor that got used as an OEM in 1997. Then the 1998 RIVAZX with RIVATNT for multi-texture 3D processing. They also needed more manufacturing support at this point and entered into a strategic partnership with TSMC to manufacture their boards.

    A lot of vendors had a good amount of success in their niches. By the late 1990s there were companies who made memory, or the survivors of the DRAM industry after ongoing price dumping issues. There were companies that made central processors like Intel. Nvidia led the charge for a new type of chip, the GPU. They invented the GPU in 1999 when they released the GeForce 256. This was the first single-chip GPU processor. This means integrated lightings, triangle setups, rendering, like the old math coprocessor but for video. Millions of polygons could be drawn on screens every second. They also released the Quadro Pro GPU for professional graphics and went public in 1999 at an IPO of $12 per share. 

    Nvidia used some of the funds from the IPO to scale operations, organically and inorganically. In 2000 they released the GeForce2 Go for laptops and acquired 3dfx, closing deals to get their 3d chips in devices from OEM manufacturers who made PCs and in the new Microsoft Xbox. By 2001 they hit $1 billion in revenues and released the GeForce 3 with a programmable GPU, using APIs to make their GPU a platform. They also released the nForce integrated graphics and so by 2002 hit 100 million processors out on the market.

    They acquired MediaQ in 2003 and partnered with game designer Blizzard to make Warcraft. They continued their success in the console market when the GeForce platform was used in the PS 3 in 2005 and by 2006 had sold half a billion processors. They also added the  CUDA architecture that year to put a general purpose GPU on the market and acquired Hybrid Graphics who develops 2D and 3D embedded software for mobile devices.

    In 2008 they went beyond the consoles and PCs when Tesla used their GPUs in cars. They also acquired PortalPlayer, who supplies semiconductors and software for personal media players and launched the Tegra mobile processor to get into the exploding mobile market. More acquisitions in 2008 but a huge win when the GeForce 9400M was put into Apple MacBooks. Then more smaller chips in 2009 when the Tegra processors were used in Android devices.

    They also continued to expand how GPUs were used. They showed up in Ultrasounds and in 2010 the Audi. By then they had the Tianhe-1A ready to go, which showed up in supercomputers and the Optimus. All these types of devices that could use a GPU meant they hit a billion processors sold in 2011, which is when they went dual core with the Tegra 2 mobile processor and entered into cross licensing deals with Intel. 

    At this point TSMC was able to pack more and more transistors into smaller and smaller places. This was a big year for larger jobs on the platform. By 2012, Nvidia got the Kepler-based GPUs out by then and their chips were used in the Titan supercomputer. They also released a virtualized GPU GRID for cloud processing. 

    It wasn’t all about large-scale computing efforts. The Tegra-3 and GTX 600 came out in 2012 as well. Then in 2013 the Tegra 4, a quad-core mobile processor, a 4G LTE mobile processor, Nvidia Shield for portable gaming, the GTX Titan, a grid appliance. In 2014 the Tegra K1 192, a shield tablet, and Maxwell. In 2015 came the TegraX1 with deep learning with 256 cores and Titan X and Jetson TX1 for smart machines, and the Nvidia Drive for autonomous vehicles. They continued that deep learning work with an appliance in 2016 with the DGX-1. The Drive got an update in the form of PX 2 for in-vehicle AI. By then, they were a 20 year old company and working on the 11th generation of the GPU and most CPU architectures had dedicated cores for machine learning options of various types. 

    2017 brought the Volta, Jetson TX2, and SHIELD was ported over to the Google Assistant. 2018 brought the Turing GPU architecture, the DGX-2, AGX Xavier, Clara, 2019 brought AGX Orin for robots and autonomous or semi-autonomous piloting of various types of vehicles. They also made the Jetson Nano and Xavier, and EGX for Edge Computing. At this point there were plenty of people who used the GPUs to mine hashes for various blockchains like with cryptocurrencies and the ARM had finally given Intel a run for their money with designs from the ARM alliance showing up in everything but a Windows device (so Apple and Android). So they tried to buy ARM from SoftBank in 2020. That deal fell through eventually but would have been an $8 billion windfall for Softbank since they paid $32 billion for ARM in 2016. 

    We probably don’t need more consolidation in the CPU sector. Standardization, yes. Some of top NVIDIA competitors include Samsung, AMD, Intel Corporation Qualcomm and even companies like Apple who make their own CPUs (but not their own GPUs as of the time of this writing). In their niche they can still make well over $15 billion a year. 

    The invention of the MOSFET came from immigrants Mohamed Atalla, originally from Egypt, and Dawon Kahng, originally from from Seoul, South Korea. Kahng was born in Korea in 1931 but immigrated to the US in 1955 to get his PhD at THE Ohio State University and then went to work for Bell Labs, where he and Atalla invented the MOSFET, and where Kahng retired. The MOSFET was an important step on the way to a microchip. 

    That microchip market with companies like Fairchild Semiconductors, Intel, IBM, Control Data, and Digital Equipment saw a lot of chip designers who maybe had their chips knocked off, either legally in a clean room or illegally outside of a clean room. Some of those ended in legal action, some didn’t. But the fact that factories overseas could reproduce chips were a huge part of the movement that came next, which was that companies started to think about whether they could just design chips and let someone else make them. That was in an era of increasing labor outsourcing, so factories could build cars offshore, and the foundry movement was born - or companies that just make chips for those who design them. 

    As we have covered in this section and many others, many of the people who work on these kinds of projects moved to the United States from foreign lands in search of a better life. That might have been to flee Europe or Asian theaters of Cold War jackassery or might have been a civil war like in Korea or Taiwan. They had contacts and were able to work with places to outsource too and given that these happened at the same time that Hong Kong, Singapore, South Korea, and Taiwan became safe and with no violence. And so the Four Asian Tigers economies exploded, fueled by exports and a rapid period of industrialization that began in the 1960s and continues through to today with companies like TSMC, a pure play foundry, or Samsung, a mixed foundry - aided by companies like Nvidia who continue to effectively outsource their manufacturing operations to companies in the areas. At least, while it’s safe to do so. 

    We certainly hope the entire world becomes safe. But it currently is not. There are currently nearly a million Rohingya refugees fleeing war in Myanmar. Over 3.5 million have fled the violence in Ukraine. 6.7 million have fled Syria. 2.7 million have left Afghanistan. Over 3 million are displaced between Sudan and South Sudan. Over 900,000 have fled Somalia. Before Ukranian refugees fled to mostly Eastern European countries, they had mainly settled in Turkey, Jordan, Lebanon, Pakistan, Uganda, Germany, Iran, and Ethiopia. Very few comparably settled in the 2 largest countries in the world: China, India, or the United States. 

    It took decades for the children of those who moved or sent their children abroad to a better life to be able to find a better life. But we hope that history teaches us to get there faster, for the benefit of all.

    Lotus: From Yoga to Software

    Lotus: From Yoga to Software

    Nelumbo nucifera, or the sacred lotus, is a plant that grows in flood plains, rivers, and deltas. Their seeds can remain dormant for years and when floods come along, blossom into a colony of plants and flowers. Some of the oldest seeds can be found in China, where they’re known to represent longevity. No surprise, given their level of nitrition and connection to the waters that irrigated crops by then. They also grow in far away lands, all the way to India and out to Australia. The flower is sacred in Hinduism and Buddhism, and further back in ancient Egypt.

    Padmasana is a Sanskrit term meaning lotus, or Padma, and Asana, or posture. The Pashupati seal from the Indus Valley civilization shows a diety in what’s widely considered the first documented yoga pose, from around 2,500 BCE. 2,700 years later (give or take a century), the Hindu author and mystic Patanjali wrote a work referred to as the Yoga Sutras. Here he outlined the original asanas, or sitting yoga poses. The Rig Veda, from around 1,500 BCE, is the oldest currently known Vedic text. It is also the first to use the word “yoga”. It describes songs, rituals, and mantras the Brahmans of the day used - as well as the Padma. Further Vedic texts explore how the lotus grew out of Lord Vishnu with Brahma in the center. He created the Universe out of lotus petals. Lakshmi went on to grow out of a lotus from Vishnu as well.

    It was only natural that humans would attempt to align their own meditation practices with the beautiful meditatios of the lotus. By the 300s, art and coins showed people in the lotus position. It was described in texts that survive from the 8th century. Over the centuries contradictions in texts were clarified in a period known as Classical Yoga, then Tantra and and Hatha Yoga were developed and codified in the Post-Classical Yoga age, and as empires grew and India became a part of the British empire, Yoga began to travel to the west in the late 1800s. By 1893, Swami Vivekananda gave lectures at the Parliament of Religions in Chicago. 

    More practicioners meant more systems of yoga. Yogendra brought asanas to the United States in 1919, as more Indians migrated to the United States. Babaji’s kriya yoga arrived in Boston in 1920. Then, as we’ve discussed in previous episodes, the United States tightened immigration in the 1920s and people had to go to India to get more training. Theos Bernard’s Hatha Yoga: The Report of a Personal Experience brought some of that knowledge home when he came back in 1947. Indra Devi opened a yoga studio in Hollywood and wrote books for housewives. She brought a whole system, or branch home. Walt and Magana Baptiste opened a studio in San Francisco. Swamis began to come to the US and more schools were opened. Richard Hittleman began to teach yoga in New York and began to teach on television in 1961. He was one of the first to seperate the religious aspect from the health benefits. By 1965, the immigration quotas were removed and a wave of teachers came to the US to teach yoga.

    The Beatles went to India in 1966 and 1968, and for many Transcendental Meditation took root, which has now grown to over a thousand training centers and over 40,000 teachers. Swamis opened meditation centers, institutes, started magazines, and even magazines. Yoga became so big that Rupert Holmes even poked fun of it in his song “Escape (The Piña Colada Song)” in 1979. Yoga had become part of the counter-culture, and the generation that followed represented a backlash of sorts.

    A common theme of the rise of personal computers is that the early pioneers were a part of that counter-culture. Mitch Kapor graduated high school in 1967, just in time to be one of the best examples of that. Kapor built his own calculator in as a kid before going to camp to get his first exposure to programming on a Bendix. His high school got one of the 1620 IBM minicomputers and he got the bug. He went off to Yale at 16 and learned to program in APL and then found Computer Lib by Ted Nelson and learned BASIC. Then he discovered the Apple II. 

    Kapor did some programming for $5 per hour as a consultant, started the first east coast Apple User Group, and did some work around town. There are generations of people who did and do this kind of consulting, although now the rates are far higher. He met a grad student through the user group named Eric Rosenfeld who was working on his dissertation and needed some help programming, so Kapor wrote a little tool that took the idea of statistical analysis from the Time Shared Reactive Online Library, or TROLL, and ported it to the microcomputer, which he called Tiny Troll. 

    Then he enrolled in the MBA program at MIT. He got a chance to see VisiCalc and meet Bob Frankston and Dan Bricklin, who introduced him to the team at Personal Software. Personal Software was founded by Dan Fylstra and Peter Jennings when they published Microchips for the KIM-1 computer. That led to ports for the 1977 Trinity of the Commodore PET, Apple II, and TRS-80 and by then they had taken Bricklin and Franston’s VisiCalc to market. VisiCalc was the killer app for those early PCs and helped make the Apple II successful.

    Personal Software brought Kapor on, as well as Bill Coleman of BEA Systems and Electronic Arts cofounder Rich Mellon. Today, software developers get around 70 percent royalties to publish software on app stores but at the time, fees were closer to 8 percent, a model pulled from book royalties. Much of the rest went to production of the box and disks, the sales and marketing, and support. Kapor was to write a product that could work with VisiCalc. By then Rosenfeld was off to the world of corporate finance so Kapor moved to Silicon Valley, learned how to run a startup, moved back east in 1979, and released VisiPlot and VisiTrend in 1981. He made over half a million dollars in the first six months in royalties. 

    By then, he bought out Rosenfeld’s shares in what he was doing, hired Jonathan Sachs, who had been at MIT earlier, where he wrote the STOIC programming language, and then went to work at Data General. Sachs worked on spreadsheet ideas at Data General with a manager there, John Henderson, but after they left Data General, and the partnership fell apart, he worked with Kapor instead. They knew that for software to be fast, it needed to be written in a lower level language, so they picked the Intel 8088 assembly language given that C wasn’t fast enough yet. The IBM PC came in 1981 and everything changed. Mitch Kapor and Jonathan Sachs started Lotus in 1982.

    Sachs got to work on what would become Lotus 1-2-3. Kapor turned out to be a great marketer and product manager. He listened to what customers said in focus groups. He pushed to make things simpler and use less jargon. They released a new spreadsheet tool in 1983 and it worked flawlessly on the IBM PC and while Microsoft had Multiplan and VisCalc was the incumbent spreadsheet program, Lotus quickly took market share from then and SuperCalc.

    Conceptually it looked similar to VisiCalc. They used the letter A for the first column, B for the second, etc. That has now become a standard in spreadsheets. They used the number 1 for the first row, the number 2 for the second. That too is now a standard. They added a split screen, also now a standard. They added macros, with branching if-then logic. They added different video modes, which could give color and bitmapping. They added an underlined letter so users could pull up a menu and quickly select the item they wanted once they had those orders memorized, now a standard in most menuing systems. They added the ability to add bar charts, pie charts, and line charts. One could even spread their sheet across multiple monitors like in a magazine. They refined how fields are calculated and took advantage of the larger amounts of memory to make Lotus far faster than anything else on the market.

    They went to Comdex towards the end of the year and introduced Lotus 1-2-3 to the world. The software could be used as a spreadsheet, but the 2 and 3 referred to graphics and database management. They did $900,000 in orders there before they went home. They couldn’t even keep up with the duplication of disks. Comdex was still invitation only. It became so popular that it was used to test for IBM compatibility by clone makers and where VisiCalc became the app that helped propel the Apple II to success, Lotus 1-2-3 became the app that helped propel the IBM PC to success.

    Lotus was rewarded with $53 million in sales for 1983 and $156 million in 1984. Mitch Kapor found himself. They quickly scaled from less than 20 to 750 employees. They brought in Freada Klein who got her PhD to be the Head of Employee Relations and charged her with making them the most progressive employer around. After her success at Lotus, she left to start her own company and later married. Sachs left the company in 1985 and moved on to focus solely on graphics software. He still responds to requests on the phpBB forum at dl-c.com.

    They ran TV commercials. They released a suite of Mac apps they called Lotus Jazz. More television commercials. Jazz didn’t go anywhere and only sold 20,000 copies. Meanwhile, Microsoft released Excel for the Mac, which sold ten times as many. Some blamed the lack os sales on the stringent copy protection. Others blamed the lack of memory to do cool stuff. Others blamed the high price. It was the first major setback for the young company. 

    After a meteoric rise, Kapor left the company in 1986, at about the height of their success. He  replaced himself with Jim Manzi. Manzi pushed the company into network applications. These would become the center of the market but were just catching on and didn’t prove to be a profitable venture just yet. A defensive posture rather than expanding into an adjacent market would have made sense, at least if anyone knew how aggressive Microsoft was about to get it would have. 

    Manzi was far more concerned about the millions of illegal copies of the software in the market than innovation though. As we turned the page to the 1990s, Lotus had moved to a product built in C and introduced the ability to use graphical components in the software but not wouldn’t be ported to the new Windows operating system until 1991 for Windows 3. By then there were plenty of competitors, including Quattro Pro and while Microsoft Excel began on the Mac, it had been a showcase of cool new features a windowing operating system could provide an application since released for Windows in 1987. Especially what they called 3d charts and tabbed spreadsheets.

    There was no catching up to Microsoft by then and sales steadily declined. By then, Lotus released Lotus Agenda, an information manager that could be used for time management, project management, and as a database. Kapor was a great product manager so it stands to reason he would build a great product to manage products. Agenda never found commercial success though, so was later open sourced under a GPL license.

    Bill Gross wrote Magellan there before he left to found GoTo.com, which was renamed to Overture and pioneered the idea of paid search advertising, which was acquired by Yahoo!. Magellan cataloged the internal drive and so became a search engine for that. It sold half a million copies and should have been profitable but was cancelled in 1990. They also released a word processor called Manuscript in 1986, which never gained traction and that was cancelled in 1989, just when a suite of office automation apps needed to be more cohesive. 

    Ray Ozzie had been hired at Software Arts to work on VisiCalc and then helped Lotus get Symphony out the door. Symphony shipped in 1984 and expanded from a spreadsheet to add on text with the DOC word processor, and charts with the GRAPH graphics program, FORM for a table management solution, and COM for communications. Ozzie dutifully shipped what he was hired to work on but had a deal that he could build a company when they were done that would design software that Lotus would then sell. A match made in heaven as Ozzie worked on PLATO and borrowed the ideas of PLATO Notes, a collaboration tool developed at the University of Illinois Champagne-Urbana  to build what he called Lotus Notes. 

    PLATO was more more than productivity. It was a community that spanned decades and Control Data Corporation had failed to take it to the mass corporate market. Ozzie took the best parts for a company and built it in isolation from the rest of Lotus. They finally released it as Lotus Notes in 1989. It was a huge success and Lotus bought Iris in 1994. Yet they never found commercial success with other socket-based client server programs and IBM acquired Lotus in 1995. That product is now known as Domino, the name of the Notes 4 server, released in 1996. Ozzie went on to build a company called Groove Networks, which was acquired by Microsoft, who appointed him one of their Chief Technology Officers. When Bill Gates left Microsoft, Ozzie took the position of Chief Software Architect he vacated. He and Dave Cutler went on to work on a project called Red Dog, which evolved into what we now know as Microsoft Azure. 

    Few would have guessed that Ozzie and Kapor’s handshake agreement on Notes could have become a real product. Not only could people not understand the concept of collaboration and productivity on a network in the late 1980s but the type of deal hadn’t been done. But Kapor by then realized that larger companies had a hard time shipping net-new software properly. Sometimes those projects are best done in isolation. And all the better if the parties involved are financially motivated with shares like Kapor wanted in Personal Software in the 1970s before he wrote Lotus 1-2-3.

    VisiCalc had sold about a million copies but that would cease production the same year Excel was released. Lotus hung on longer than most who competed with Microsoft on any beachhead they blitzkrieged. Microsoft released Exchange Server in 1996 and Notes had a few good years before Exchange moved in to become the standard in that market. Excel began on the Mac but took the market from Lotus eventually, after Charles Simonyi stepped in to help make the product great. 

    Along the way, the Lotus ecosystem created other companies, just as they were born in the Visi ecosystem. Symantec became what we now call a “portfolio” company in 1985 when they introduced NoteIt, a natural language processing tool used to annotate docs in Lotus 1-2-3. But Bill Gates mentioned Lotus by name multiple times as a competitor in his Internet Tidal Wave memo in 1995. He mentioned specific features, like how they could do secure internet browsing and that they had a web publisher tool - Microsoft’s own FrontPage was released in 1995 as well. He mentioned an internet directory project with Novell and AT&T. Active Directory was released a few years later in 1999, after Jim Allchin had come in to help shepherd LAN Manager. Notes itself survived into the modern era, but by 2004 Blackberry released their Exchange connector before they released the Lotus Domino connector. That’s never a good sign.

    Some of the history of Lotus is covered in Scott Rosenberg’s 2008 book, Dreaming in Code. Others are documented here and there in other places. Still others are lost to time.

    Kapor went on to invest in UUNET, which became a huge early internet service provider. He invested in Real Networks, who launched the first streaming media service on the Internet. He invested in the creators of Second Life. He never seemed vindictive with Microsoft but after AOL acquired Netscape and Microsoft won the first browser war, he became the founding chair of the Mozilla Foundation and so helped bring Firefox to market. By 2006, Firefox took 10 percent of the market and went on to be a dominant force in browsers. Kapor has also sat on boards and acted as an angel investor for startups ever since leaving the company he founded.

    He also flew to Wyoming in 1990 after he read a post on The WELL from John Perry Barlow. Barlow was one of the great thinkers of the early Internet. They worked with Sun Microsystems and GNU Debugging Cypherpunk John Gilmore to found the Electronic Frontier Foundation, or EFF. The EFF has since been the nonprofit who leads the fight for “digital privacy, free speech, and innovation.” So not everything is about business.

     

     

    Section 230 and the Concept of Internet Exceptionalism

    Section 230 and the Concept of Internet Exceptionalism

    We covered computer and internet copyright law in a previous episode. That type of law began with interpretations that tried to take the technology out of cases so they could be interpreted as though what was being protected was a printed work, or at least it did for a time. But when it came to the internet, laws, case law, and their knock-on effects, the body of jurisprudence work began to diverge. 

    Safe Harbor mostly refers to the Online Copyright Infringement Liability Limitation Act, or OCILLA for short, was a law passed in the late 1980s that  shields online portals and internet service providers from copyright infringement. Copyright infringement is one form of immunity, but more was needed. Section 230 was another law that protects those same organizations from being sued for 3rd party content uploaded on their sites. That’s the law Trump wanted overturned during his final year in office but given that the EU has Directive 2000/31/EC, Australia has the Defamation Act of 2005, Italy has the Electronic Commerce Directive 2000, and lots of other countries like England and Germany have had courts find similarly, it is now part of being an Internet company. Although the future of “big tech” cases (and the damage many claim is being done to democracy) may find it refined or limited.

    That’s because the concept of Internet Exceptionalism itself is being reconsidered now that the internet is here to stay. Internet Exceptionalism is a term that notes that laws that diverge from precedents for other forms of media distribution. For example, a newspaper can be sued for liable or defamation, but a website is mostly shielded from such suits because the internet is different. Pages are available instantly, changes be made instantly, and the reach is far greater than ever before. The internet has arguably become the greatest tool to spread democracy and yet potentially one of its biggest threats. Which some might have argued about newspapers, magazines, and other forms of print media in centuries past.

    The very idea of Internet Exceptionalism has eclipsed the original intent. Chris Cox and Ron Widen initially intended to help fledgling Internet Service Providers (ISPs) jumpstart content on the internet. The internet had been privatized in 1995 and companies like CompuServe, AOL, and Prodigy were already under fire for the content on their closed networks. Cubby v CompuServe in 1991 had found that online providers weren’t considered publishers of content and couldn’t be held liable for free speech practiced on their platforms in part because they did not exercise editorial control of that content. Stratton Oakmont v Prodigy found that Prodigy did have editorial control (and in fact advertised themselves as having a better service because of it) and so could be found liable like a newspaper would. Cox and Widen were one of the few conservative and liberal pairs of lawmakers who could get along in the decisive era when Newt Gingrich came to power and tried to block everything Bill Clinton tried to do. 

    Yet there were aspects of the United States that were changing outside of politics. Congress spent years negotiating a telecommunications overhaul bill that came to be known as The Telecommunications Act of 1996. New technology led to new options. Some saw content they found to be indecent and so the Communications Decency Act (or Title V of the Telecommunications Act) was passed in 1996, but in Reno v ACLU found to be a violation of the first amendment, and struck down by the Supreme Court in 1997. Section 230 of that act was specifically about the preservation of free speech and so severed from the act and stood alone. It would be adjudicated time and time and eventually became an impenetrable shield that protects online providers from the need to scan every message posted to a service to see if it would get them sued. Keep in mind that society itself was changing quickly in the early 1990s. Tipper Gore wanted to slap a label on music to warn parents that it had explicit lyrics. The “Satanic Panic” as it’s called by history reused tropes such as cannibalism and child murder to give the moral majority an excuse to try to restrict that which they did not understand. Conservative and progressive politics have always been a 2 steps forward and 1 step back truce. Heavy metal would seem like nothin’ once parents heard the lyrics of gagster rap. 

    But Section 230 continued on. It stated that “No provider or user of an interactive computer service shall be treated as the publisher or speaker of any information provided by another information content provider.” It only took 27 words to change the world. They said that the people that host the content can’t be sued for the content because, as courts interpreted it, it’s free speech. Think of a public forum like a hall on a college campus that might restrict one group from speaking and so suppress speech or censer a group. Now, Section 230 didn’t say it wasn’t allowed to screen material but instead shielded providers from being held liable for that material. The authors of the bill felt that if providers would be held liable for any editing that they wouldn’t do any. Now providers could edit some without reviewing every post. And keep in mind the volume of posts in message boards and of new websites had already become too much in the late 1990s to be manually monitored. Further, as those companies became bigger business they became more attractive to law suits. 

    Section 230 had some specific exclusions. Any criminal law could still be applied, as could state, sex trafficking, and privacy laws. Intellectual property laws also remained untouched, thus OCILLA. To be clear, reading the law, the authors sought to promote the growth of the internet - and it worked. Yelp gets sued over revues but cases are dismissed. Twitter can get sued over a Tweet when someone doesn’t like what is said, but it’s the poster and not Twitter who is liable. Parody sites, whistleblower sites, watchdog sites, revue sites, blogs, and an entire industry was born, which each player of what would later be known as the Web 2.0 market could self-regulate themselves. 

    Those businesses grew far beyond the message boards of the 1990s. This was also a time when machine learning became more useful. A site like Facebook could show a feed of posts not in reverse chronological order, but instead by “relevance.” Google could sell ads and show them based on the relevance of a search term. Google could buy YouTube and they could have ads on videos. Case after case poked at the edges of what could be used to hold a site liable. The fact that the courts saw a post on Reddit as free speech, no matter how deplorable the comments, provided a broad immunity to liability that was, well, exceptional in a way. 

    Some countries could fine or imprison people if they posted something negative about the royal family or party in charge. Some of those countries saw the freedom of speech so important as a weapon that could be used against the US in a way. The US became a safe haven in a way to free speech and many parts of the internet were anonymous. In this way (as was previously done with films and other sources of entertainment and news) the US began to export the culture of free speech. But every country also takes imports. Some of those were real, true ideas homegrown or brought in from abroad. Early posters of message boards maybe thought the Armenian Genocide was a hoax - or the Holocaust. A single post could ruin a career. Craigslist allowed for sex trafficking and while they eventually removed that, sites like Backpage have received immunity. So even some of the exceptions are, um, not. Further, extremist groups use pages to spread propaganda and even recruit soldiers to spread terror. 

    The courts found that sites were immune to suits over fake profiles on dating sites - even if it was a famous person and the person was getting threatening calls. The courts initially found sites needed to take down content if they were informed it was libelous - but have received broad immunity even when they don’t due to the sheer amount of content. Batzel v Smith saw a lawyers firm ruined over false reports she was the granddaughter of Nazi Heinrich Himmler and the beneficiary of Nazi art theft, even though she wasn’t - she too lost her case. Sites provide neutral tools and so are shielded from defamation - even if they’re neutralish you rarely see them held to account. In Goddard v. Google, the Google Keyword Tool recommended that advertisers include the word “free” in mobile content, which Goddard claimed led to fraudulent subscription service recruitment. This was machine learning-based recommendations. The court again found provided the Keyword Tool was neutral that advertisers could adopt or reject the recommendation. 

    Still, time and time again the idea of safe harbor for internet companies and whether internet exceptionalism should continue comes up. The internet gave a voice to the oppressed, but also to the oppressors. That’s neutrality in a way, except that the oppressors (especially when state sponsored actors are involved) often have more resources to drown out other voices, just like in real life. Some have argued a platform like Facebook should be held accountable for their part in the Capitol riots, which is to say as a place where people practiced free speech. Others look to Backpage as facilitating the exploitation of children or as a means of oppression. Others still see terrorist networks as existing and growing because of the ability to recruit online. 

    The Supreme Court is set to hear docket number 21-1333 in 2022. Gonzalez v. Google was brought by Reynaldo Gonzalez, and looks at whether 230 can immunize Google even though they have made targeted recommendations - in this case when ISIS used YouTube vides to recruit new members - through the  recommendation algorithm. An algorithm that would be neutral. But does a platform as powerful have a duty to do more, especially when there’s a chance that Section 230 bumps up against anti-terrorism legislation. Again and again the district courts in the United States have found section 230 provides broad immunization to online content providers. Now, the Supreme Court will weigh in. After that, billions of dollars may have to be pumped into better content filtration or they may continue to apply broad first amendment guidance. 

    The Supreme Court is packed with “originalists”. They still have phones, which the framers did not. The duty that common law places on those who can disseminate negligent or reckless content has lost the requirement for reasonable care due to the liability protections afforded purveyors of content by Section 230. This has given rise to hate speech and misinformation. John Perry Barlow’s infamous A Declaration of the Independence of Cyberspace in protest of the CDA was supported by Section 230 of that same law. But the removal of the idea and duty of reasonable care and the exemptions have now removed any accountability from what seems like any speech. Out of the ashes of accountability the very concept of free speech and where the duty of reasonable care lies may be reborn. We now have the ability to monitor via machine learning, we’ve now redefined what it means to moderate, and there’s now a robust competition for eyeballs on the internet. We’ve also seen how a lack of reasonable standards can lead to real life consequences and that an independent cyberspace can bleed through into the real world. 

    If the Supreme Court simply upholds findings from the past then the movement towards internet sovereignty may accelerate or may stay the same. Look to where venture capital flows for clues as to how the First Amendment will crash into the free market, and see if its salty waters leave data and content aggregators with valuations far lower than where they once were. The asset of content may some day become a liability with injuries that could provide an existential threat to the owner. The characters may walk the astral plane but eventually must return to the prime material plane along their tether to take a long rest or face dire consequences. The world simply can’t continue to become more and more toxic - and yet there’s a reason the First Amendment is, well, first.

    Bluetooth: From Kings to Personal Area Networks

    Bluetooth: From Kings to Personal Area Networks

    Bluetooth The King
    Ragnar Lodbrok was a legendary Norse king, conquering parts of Denmark and Sweden. And if we’re to believe the songs, he led some of the best raids against the Franks and the the loose patchwork of nations Charlemagne put together called the Holy Roman Empire. 

    We use the term legendary as the stories of Ragnar were passed down orally and don’t necessarily reconcile with other written events. In other words, it’s likely that the man in the songs sung by the bards of old are likely in fact a composite of deeds from many a different hero of the norse.
     
    Ragnar supposedly died in a pit of snakes at the hands of the Northumbrian king and his six sons formed a Great Heathen Army to avenge their father. His sons ravaged modern England int he wake of their fathers death before becoming leaders of various lands they either inherited or conquered. One of those sons, Sigurd Snake-in-the-Eye, returned home to rule his lands and had children, including Harthacnut. He in turn had a son named Gorm. 

    Gorm the Old was a Danish king who lived to be nearly 60 in a time when life expectancy for most was about half that. Gorm raised a Jelling stone in honor of his wife Thyra. As did his son, in the honor of his wife. That stone is carved with runes that say:

    “King Haraldr ordered this monument made in memory of Gormr, his father, and in memory of Thyrvé, his mother; that Haraldr who won for himself all of Denmark and Norway and made the Danes Christian.”

    That stone was erected by a Danish king named Herald Gormsson. He converted to Christianity as part of a treaty with the Holy Roman Emperor of the day. He united the tribes of Denmark into a kingdom. One that would go on to expand the reach and reign of the line. Just as Bluetooth would unite devices. Even the logo is a combination of runes that make up his initials HB. Once united, their descendants would go on to rule Denmark, Norway, and England. For a time. Just as Bluetooth would go on to be an important wireless protocol. For a time. 

    Personal Area Networks
    Many early devices shipped with infrared so people could use a mouse or keyboard. But those never seemed to work so great. And computers with a mouse and keyboard and drawing pad and camera and Zip drive and everything else meant that not only did devices have to be connected to sync but they also had to pull a lot of power and create an even bigger mess on our desks. 

    What the world needed instead was an inexpensive chip that could communicate wirelessly and not pull a massive amount of power since some would be in constant communication. And if we needed a power cord then might as well just use USB or those RS-232 interfaces (serial ports) that were initially developed in 1960 - that were slow and cumbersome. And we could call this a Personal Area Network, or PAN. 

    The Palm Pilot was popular, but docking and pluging in that serial port was not exactly optimal. Yet every ATX motherboard had a port or two. So a Bluetooth Special Interest Group was formed to conceive and manage the standard in 1988 and while initially had half a dozen companies now has over 30,000. The initial development started in the late 1990s with Ericcson. It would use short-range UHF radio waves in the 2.402 GHz and 2.48 GHz bands to exchange data with computers and cell phones, which were evolving into mobile devices at the time.

    The technology was initially showcased at COMDEX in 1999. Within a couple of years there were phones that could sync, kits for cars, headsets, and chips that could be put into devices - or cards or USB adapters, to get a device to sync 721 Kbps. We could add 2 to 8 Bluetooth secondary devices that paired to our primary. They then frequency hopped using their Bluetooth device address provided by the primary, which sends a radio signal to secondaries with a range of addresses to use. The secondaries then respond with the frequency and clock state. And unlike a lot of other wireless technologies, it just kinda’ worked.

    And life seemed good. Bluetooth went to the IEEE, which had assigned networking the 802 standard with Ethernet being 802.3 and Wi-Fi being 802.11. So Personal Area Networks became 802.15, with Bluetooth 1.1 becoming 802.15.1. And the first phone shipped in 2001, the Sony Ericsson T39. 

    Bluetooth 2 came in 2005 and gave us 2.1 Mbps speeds and increased the range from 10 to 30 meters. By then, over 5 million devices were shipping every week. More devices mean we have a larger attack surface space. And security researchers were certainly knocking at the door. Bluetooth 2.1 added secure simple pairing. Then Bluetooth 3 in 2009 bringing those speeds up to 24 Mbps and once connected allowing Wi-Fi to pick up connections once established. But we were trading speed for energy and this wasn’t really the direction Bluetooth needed to go. Even if a billion devices had shipped by the end of 2006.

    Bluetooth 4
    The mobility era was upon us and it was increasingly important, not just for the ARM chips, but also for the rest of the increasing number of devices, to use less power. Bluetooth 4 came along in 2010 and was slower at 1 Mbps, but used less energy. This is when the iPhone 4S line fully embraced the technology, helping make it a standard. 

    While not directly responsible for the fitness tracker craze, it certainly paved the way for a small coin cell battery to run these types of devices for long periods of time. And it allowed for connecting devices 100 meters, or well over 300 feet away. So leave the laptop in one room and those headphones should be fine in the next. 

    And while we’re at it, maybe we want those headphones to work on two different devices. This is where Multipoint comes into play. That’s the feature of Bluetooth 4 that allows those devices to pass seamlessly between the phone and the laptop, maintaining a connection to each. Apple calls their implementation of this feature Handoff. 

    Bluetooth 5 came in 2016, allowing for connections up to 240 meters, or around 800 feet. Well, according to what’s between us and our devices, as with other protocols. We also got up to 2 Mbps, which dropped as we moved further away from devices. Thus we might get buffering issues or slower transfers with weaker connections. But not outright dropping the connection.

    Bluetooth Evolves
    Bluetooth was in large part developed to allow our phones to sync to our computers. Most don’t do that any more. And the developers wanted to pave the way for wireless headsets. But it also allowed us to get smart scales, smart bulbs, wearables like smart watches and glasses, Bluetooth printers, webcams, keyboards, mice, GPS devices, thermostats, and even a little device that tells me when I need to water the plants. Many home automation devices, or IoT as we seem to call them these days began as Bluetooth but given that we want them to work when we take all our mostly mobile computing devices out of the home, many of those have moved over to Wi-Fi these days.

    Bluetooth was initially conceived as a replacement for the serial port. Higher throughput needs moved to USB and USB-C. Lower throughput has largely moved to Bluetooth, with the protocol split between Low Energy and higher bandwidth application which with high definition audio now includes headphones. Once the higher throughput needs went to parallel and SCSI but now there are so many other options. 

    And the line is blurred between what goes where. Billions of routers and switches have been sold, billions of wireless access points. Systems on a Chip now include Wi-Fi and Bluetooth together on the same chip. The programming languages for native apps have also given us frameworks and APIs where we can establish a connection over 5G, Wi-Fi, or Bluetooth, and then hand them off where the needs diverge. Seamless to those who use our software and elegant when done right.

    Today over four billion bluetooth devices ship per year, growing at about 10 percent a year. The original needs that various aspects of Bluetooth was designed for have moved to other protocols and the future of the Personal Area Network may be at least in part moved to Wi-Fi or 5G. But for now it’s a standard that has aged well and continues to make life easier for those who use it.

    One History Of 3D Printing

    One History Of 3D Printing

    One of the hardest parts of telling any history, is which innovations are significant enough to warrant mention. Too much, and the history is so vast that it can't be told. Too few, and it's incomplete. Arguably, no history is ever complete. Yet there's a critical path of innovation to get where we are today, and hundreds of smaller innovations that get missed along the way, or are out of scope for this exact story.

    Children have probably been placing sand into buckets to make sandcastles since the beginning of time. Bricks have survived from round 7500BC in modern-day Turkey where humans made molds to allow clay to dry and bake in the sun until it formed bricks. Bricks that could be stacked. And it wasn’t long before molds were used for more. Now we can just print a mold on a 3d printer.
     
    A mold is simply a block with a hollow cavity that allows putting some material in there. People then allow it to set and pull out a shape. Humanity has known how to do this for more than 6,000 years, initially with lost wax casting with statues surviving from the Indus Valley Civilization, stretching between parts of modern day Pakistan and India. That evolved to allow casting in gold and silver and copper and then flourished in the Bronze Age when stone molds were used to cast axes around 3,000 BCE. The Egyptians used plaster to cast molds of the heads of rulers. So molds and then casting were known throughout the time of the earliest written works and so the beginning of civilization.

    The next few thousand years saw humanity learn to pack more into those molds, to replace objects from nature with those we made synthetically, and ultimately molding and casting did its part on the path to industrialization. As we came out of the industrial revolution, the impact of all these technologies gave us more and more options both in terms of free time as humans to think as well as new modes of thinking. And so in 1868 John Wesley Hyatt invented injection molding, patenting the machine in 1872. And we were able to mass produce not just with metal and glass and clay but with synthetics. And more options came but that whole idea of a mold to avoid manual carving and be able to produce replicas stretched back far into the history of humanity.

    So here we are on the precipice of yet another world-changing technology becoming ubiquitous. And yet not. 3d printing still feels like a hobbyists journey rather than a mature technology like we see in science fiction shows like Star Trek with their replicators or printing a gun in the Netflix show Lost In Space. In fact the initial idea of 3d printing came from a story called Things Pass By written all the way back in 1945!

    I have a love-hate relationship with 3D printing. Some jobs just work out great. Others feel very much like personal computers in the hobbyist era - just hacking away until things work. It’s usually my fault when things go awry. Just as it was when I wanted to print things out on the dot matrix printer on the Apple II. Maybe I fed the paper crooked or didn’t check that there was ink first or sent the print job using the wrong driver. One of the many things that could go wrong. 

    But those fast prints don’t match with the reality of leveling and cleaning nozzles and waiting for them to heat up and pulling filament out of weird places (how did it get there, exactly)! Or printing 10 add-ons for a printer to make it work the way it probably should have out of the box. 

    Another area where 3d printing is similar to the early days of the personal computer revolution is that there are a few different types of technology in use today. These include color-jet printing (CJP), direct metal printing (DMP), fused deposition modeling (FDM), Laser Additive Manufacturing (LAM, multi-jet printing (MJP), stereolithography (SLA), selective laser melting (SLM), and selective laser sintering (SLS). Each could be better for a given type of print job to be done. Some forms have flourished while others are either their infancy or have been abandoned like extinct languages.

    Language isolates are languages that don’t fit into other families. Many are the last in a branch of a larger language family tree. Others come out of geographically isolated groups. Technology also has isolates. Konrad Zuse built computers in pre-World War II Germany and after that aren’t considered to influence other computers. In other words, every technology seems to have a couple of false starts. Hideo Kodama filed the first patent to 3d print in 1980 - but his method of using UV lights to harden material doesn’t get commercialized. 

    Another type of 3d printing includes printers that were inkjets that shot metal alloys onto surfaces. Inkjet printing was invented by Ichiro Endo at Canon in the 1950s, supposedly when he left a hot iron on a pen and ink bubbled out. Thus the “Bubble jet” printer. And Jon Vaught at HP was working on the same idea at about the same time. These were patented and used to print images from computers over the coming decades.

    Johannes Gottwald patented a printer like this in 1971. Experiments continued through the 1970s when companies like Exxon were trying to improve various prototyping processes. Some of their engineers joined an inventor Robert Howard in the early 1980s to found a company called Howtek and they produced the Pixelmaster, using hot-melt inks to increment the ink jet with solid inks, which then went on to be used by Sanders Prototype, which evolved into a company called Solidscape to market the Modelmaker. And some have been used to print solar cells, living cells, tissue, and even edible birthday cakes.

    That same technique is available with a number of different solutions but isn’t the most widely marketable amongst the types of 3D printers available.

    SLA
    There’s often a root from which most technology of the day is derived. Charles, or Chuck, Hull coined the term stereolithography, where he could lay down small layers of an object and then cure the object with UV light, much as the dentists do with fillings today. This is made possibly by photopolymers, or plastics that are easily cured by an ultraviolet light. He then invented the stereolithography apparatus, or SLA for short, a machine that printed from the bottom to the top by focusing a laser on photopolymer while in a liquid form to cure the plastic into place. He worked on it in 1983, filed the patent in 1984, and was granted the patent in 1986. 

    Hull also developed a file format for 3D printing called STL. STL files describe the surface of a three-dimensional object, geometrically using Cartesian coordinates. Describing coordinates and vectors means we can make objects bigger or smaller when we’re ready to print them. 3D printers print using layers, or slices. Those can change based on the filament on the head of a modern printer, the size of the liquid being cured, and even the heat of a nozzle. So the STL file gets put into a slicer that then converts the coordinates on the outside to the polygons that are cured. These are polygons in layers, so they may appear striated rather than perfectly curved according to the size of the layers. However, more layers take more time and energy. Such is the evolution of 3D printing.

    Hull then founded a company called 3D Systems in Valencia California to take his innovation to market. They sold their first printer, the SLA-1 in 1988. New technologies start out big and expensive. And that was the case with 3D Systems. They initially sold to large engineering companies but when solid-state lasers came along in 1996 they were able to provide better systems for cheaper. 

    Languages also have other branches. Another branch in 3d printing came in 1987, just before the first SLA-1 was sold. 

    Carl Deckard  and his academic adviser Joe Beaman at the University of Texas worked on a DARPA grant to experiment with creating physical objects with lasers. They formed a company to take their solution to market called DTM and filed a patent for what they called selective laser sintering. This compacts and hardens a material with a heat source without having to liquify it. So a laser, guided by a computer, can move around a material and harden areas to produce a 3D model. Now in addition to SLA we had a second option, with the release of the Sinterstation 2500plus. Then 3D Systems then acquired DTM for $45 million in 2001.

    FDM
    After Hull published his findings for SLA and created the STL format, other standards we use today emerged. FDM is short for Fused Deposition Modeling and was created by Scott Crump in 1989. He then started a company with his wife Lisa to take the product to market, taking the company public in 1994. Crump’s first patent expired in 2009. 

    In addition to FDM, there are other formats and techniques. AeroMat made the first 3D printer that could produce metal in 1997. These use a laser additive manufacturing process, where lasers fuse powdered titanium alloys. Some go the opposite direction and create out of bacteria or tissue. That began in 1999, when Wake Forest Institute of Regenerative medicine grew a 3D printed urinary bladder in a lab to be used as a transplant. We now call this bioprinting and can take tissue and lasers to rebuild damaged organs or even create a new organ. Organs are still in their infancy with success trials on smaller animals like rabbits. Another aspect is printing dinner using cell fibers from cows or other animals.

    There are a number of types of materials used in 3D printing. Most printers today use a continuous feed of one of these filaments, or small coiled fibers of thermoplastics that melt instead of burn when they’re heated up. The most common in use today is PLA, or polylactic acid, is a plastic initially created by Wall Carothers of DuPont, the same person that brought us nylon, neoprene, and other plastic derivatives. It typically melts between 200 and 260 degrees Celsius. Printers can also take ABS filament, which is short for acrylonitrile-butadien-styerene. Other filament types include HIPS, PET, CPE, PVA, and their derivative forms. 

    Filament is fed into a heated extruder assembly that melts the plastic. Once melted, filament extrudes into place through a nozzle as a motor sends the nozzle on a x and y axis per layer. 

    Once a layer of plastic is finished being delivered to the areas required to make up the desired slice, the motor moves the extruder assembly up or down on a z axis between layers. Filament is just between 1.75 millimeters and 3 millimeters and comes in spools between half a kilogram and two kilograms.

    These thermoplastics cool very quickly. Once all of the slices are squirted into place, the print is removed from the bed and the nozzle cools off. Filament comes in a number of colors and styles. For example, wood fibers can be added to filament to get a wood-grained finish. Metal can be added to make prints appear metallic and be part metal. 

    Printing isn’t foolproof, though. Filament often gets jammed or the spool gets stuck, usually when something goes wrong. Filament also needs to be stored in a temperature and moisture controlled location or it can cause jobs to fail. Sometimes the software used to slice the .stl file has an incorrect setting, like the wrong size of filament. But in general, 3D printing using the FDM format is pretty straight forward these days. Yet this is technology that should have moved faster in terms of adoption. The past 10 years have seen more progress than the previous ten though. Primarily due to the maker community.

    Enter the Makers
    The FDM patent expired in 2009. In 2005, a few years before the FDM patent expired, Dr. Adrian Bowyer started a project to bring inexpensive 3D printers to labs and homes around the world. That project evolved into what we now call the Replicating Rapid Prototyper, or RepRap for short. 

    RepRap evolved into an open source concept to create self-replicating 3D printers and by 2008, the Darwin printer was the first printer to use RepRap. As a community started to form, more collaborators designed more parts. Some were custom parts to improve the performance of the printer, or replicate the printer to become other printers. Others held the computing mechanisms in place. Some even wrote code to make the printer able to boot off a MicroSD card and then added a network interface so files could be uploaded to the printer wirelessly.

    There was a rising tide of printers. People were reading about what 3D printers were doing and wanted to get involved. There was also a movement in the maker space, so people wanted to make things themselves. There was a craft to it. Part of that was wanting to share. Whether that was at a maker space or share ideas and plans and code online. Like the RepRap team had done. 

    One of those maker spaces was NYC Resistor, founded in 2007. Bre Pettis, Adam Mayer, and Zach Smith from there took some of the work from the RepRap project and had ideas for a few new projects they’d like to start. The first was a site that Zach Smith created called Thingiverse. Bre Pettis joined in and they allowed users to upload .stl files and trade them. It’s now the largest site for trading hundreds of thousands of designs to print about anything imaginable. Well, everything except guns.

    Then comes 2009. The patent for FDM expires and a number of companies respond by launching printers and services. Almost overnight the price for a 3D printer fell from $10,000 to $1,000 and continued to drop. Shapeways had created a company the year before to take files and print them for people. Pettis, Mayer, and Smith from NYC Resistor also founded a company called MakerBot Industries.

    They’d already made a little bit of a name for themselves with the Thingiverse site. They knew the mind of a maker. And so they decided to make a kit to sell to people that wanted to build their own printers. They sold 3,500 kits in the first couple of years. They had a good brand and knew the people who bought these kinds of devices. So they took venture funding to grow the company. So they raised $10M in funding in 2011 in a round led by the Foundry Group, along with Bezos, RRE, 500 Startups and a few others.

    They hired and grew fast. Smith left in 2012 and they were getting closer and closer with Stratasys, who if we remember were the original creators of FDM. So Stratasys ended up buying out the company in 2013 for $403M. Sales were disappointing so there was a changeup in leadership, with Pettis leaving and they’ve become much more about additive manufacturing than a company built to appeal to makers. And yet the opportunity to own that market is still there.

    This was also an era of Kickstarter campaigns. Plenty of 3D printing companies launched through kickstarter including some to take PLA (a biodegradable filament) and ABS materials to the next level. The ExtrusionBot, the MagicBox, the ProtoPlant, the Protopasta, Mixture, Plybot, Robo3D, Mantis, and so many more. 

    Meanwhile, 3D printing was in the news. 2011 saw the University of Southhampton design a 3d printed aircraft. Ecologic printing cars, and practically every other car company following suit that they were fabricating prototypes with 3d printers, even full cars that ran. Some on their own, some accidentally when parts are published in .stl files online violating various patents. 

    Ultimaker was another RepRap company that came out of the early Darwin reviews. Martijn Elserman, Erik de Bruin, and Siert Wijnia who couldn’t get the Darwin to work so they designed a new printer and took it to market. After a few iterations, they came up with the Ultimaker 2 and have since been growing and releasing new printers 

    A few years later, a team of Chinese makers, Jack Chen, Huilin Liu, Jingke Tang, Danjun Ao, and Dr. Shengui Chen took the RepRap designs and started a company to manufacturing (Do It Yourself) kits called Creality. They have maintained the open source manifesto of 3D printing that they inherited from RepRap and developed version after version, even raising over $33M to develop the Ender6 on Kickstarter in 2018, then building a new factory and now have the capacity to ship well over half a million printers a year.

    The future of 3D Printing
    We can now buy 3D printing pens, over 170 3D Printer manufacturers including 3D systems, Stratasys, and Ceality but also down-market solutions like Fusion3, Formlabs, Desktop Metal, Prusa, and Voxel8. There’s also a RecycleBot concept and additional patents expiring every year. 

    There is little doubt that at some point, instead of driving to Home Depot to get screws or basic parts, we’ll print them. Need a new auger for the snow blower? Just print it. Cover on the weed eater break?  Print it. Need a dracolich mini for the next Dungeons and Dragons game? Print it. Need a new pinky toe. OK, maybe that’s a bit far. Or is it? In 2015, Swedish Cellink releases bio-ink made from seaweed and algae, which could be used to print cartilage and later released the INKREDIBLE 3D printer for bio printing.

    The market in 2020 was valued at $13.78 billion with 2.1 million printers shipped. That’s expected to grow at a compound annual growth rate of 21% for the next few years. But a lot of that is healthcare, automotive, aerospace, and prototyping still. Apple made the personal computer simple and elegant. But no Apple has emerged for 3D printing. Instead it still feels like the Apple II era, where there are 3D printers in a lot of schools and many offer classes on generating files and printing. 

    3D printers are certainly great for prototypers and additive manufacturing. They’re great for hobbyists, which we call makers these days. But there will be a time when there is a printer in most homes, the way we have electricity, televisions, phones, and other critical technologies. But there are a few things that have to happen first, to make the printers easier to use. These include:

    • Every printer needs to automatically level. This is one of the biggest reasons jobs fail and new users become frustrated.
    • More consistent filament. Spools are still all just a little bit different.
    • Printers need sensors in the extruder that detect if a job should be paused because the filament is jammed, humid, or caught. This adds the ability to potentially resume print jobs and waste less filament and time.
    • Automated slicing in the printer microcode that senses the filament and slices.
    • Better system boards (e.g. there’s a tool called Klipper that moves the math from the system board on a Creality Ender 3 to a Raspberry Pi).
    • Cameras on the printer should watch jobs and use TinyML to determine if they are going to fail as early as possible to halt printing so it can start over.
    • Most of the consumer solutions don’t have great support. Maybe users are limited to calling a place in a foreign country where support hours don’t make sense for them or maybe the products are just too much of a hacker/maker/hobbyist solution.
    • There needs to be an option for color printing. This could be a really expensive sprayer or ink like inkjet printers use at first We love to paint minis we make for Dungeons and Dragons but could get amazingly accurate resolutions to create amazing things with automated coloring. 

    For a real game changer, the RecycleBot concept needs to be merged with the printer. Imagine if we dropped our plastics into a recycling bin that 3D printers of the world used to create filament. This would help reduce the amount of plastics used in the world in general. And when combined with less moving around of cheap plastic goods that could be printed at home, this also means less energy consumed by transporting goods.

    The 3D printing technology is still a generation or two away from getting truly mass-marketed. Most hobbyists don’t necessarily think of building an elegant, easy-to-use solution because they are so experienced it’s hard to understand what the barriers of entry are for any old person. But the company who finally manages to crack that nut might just be the next Apple, Microsoft, or Google of the world.

    Adobe: From Pueblos to Fonts and Graphics to Marketing

    Adobe: From Pueblos to Fonts and Graphics to Marketing

    The Mogollon culture was an indigenous culture in the Western United States and Mexico that ranged from New Mexico and Arizona to Sonora, Mexico and out to Texas. They flourished from around 200 CE until the Spanish showed up and claimed their lands. The cultures that pre-existed them date back thousands more years, although archaeology has yet to pinpoint exactly how those evolved. Like many early cultures, they farmed and foraged. As they farmed more, their homes become more permanent and around 800 CE they began to create more durable homes that helped protect them from wild swings in the climate. We call those homes adobes today and the people who lived in those peublos and irrigated water, often moving higher into mountains, we call the Peubloans - or Pueblo Peoples.

    Adobe homes are similar to those found in ancient cultures in what we call Turkey today. It’s an independent evolution.

    Adobe Creek was once called Arroyo de las Yeguas by the monks from Mission Santa Clara and then renamed to San Antonio Creek by a soldier Juan Prado Mesa when the land around it was given to him by the governor of Alto California at the time, Juan Bautista Alvarado. That’s the same Alvarado as the street if you live in the area. The creek runs for over 14 miles north from the Black Mountain and through Palo Alto, California. The ranchers built their adobes close to the creeks. American settlers led the Bear Flag Revolt in 1846, and took over the garrison of Sonoma, establishing the California Republic - which covered much of the lands of the Peubloans. There were only 33 of them at first, but after John Fremont (yes, he of whom that street is named after as well) encouraged the Americans, they raised an army of over 100 men and Fremont helped them march on Sutter’s fort, now with the flag of the United States, thanks to Joseph Revere of the US Navy (yes, another street in San Francisco bears his name). 

    James Polk had pushed to expand the United States. Manfiest Destiny. Remember The Alamo. Etc. The fort at Monterey fell, the army marched south. Admiral Sloat got involved. They named a street after him. General Castro surrendered - he got a district named after him. Commodore Stockton announced the US had taken all of Calfironia soon after that. Manifest destiny was nearly complete. He’s now basically the patron saint of a city, even if few there know who he was. The forts along the El Camino Real that linked the 21 Spanish Missions, a 600-mile road once walked by their proverbial father, Junípero Serra following the Portolá expedition of 1769, fell. Stockton took each, moving into Los Angeles, then San Diego. Practically all of Alto California fell with few shots. This was nothing like the battles for the independence of Texas, like when Santa Anna reclaimed the Alamo Mission. 

    Meanwhile, the waters of Adobe Creek continued to flow. The creek was renamed in the 1850s after Mesa built an adobe on the site. Adobe Creek it was. Over the next 100 years, the area evolved into a paradise with groves of trees and then groves of technology companies. The story of one begins a little beyond the borders of California. 

    Utah was initialy explored by Francisco Vázquez de Coronado in 1540 and settled by Europeans in search of furs and others who colonized the desert, including those who established the Church of Jesus Christ of Latter-day Saints, or the Mormons - who settled there in 1847, just after the Bear Flag Revolt. The United States officially settled for the territory in 1848 and Utah became a territory and after a number of map changes wher ethe territory got smaller, was finally made a state in 1896. The University of Utah had been founded all the way back in 1850, though - and re-established in the 1860s. 

    100 years later, the University of Utah was a hotbed of engineers who pioneered a number of graphical advancements in computing. John Warnock went to grad school there and then went on to co-found Adobe and help bring us PostScript. Historically, PS, or Postscript was a message to be placed at the end of a letter, following the signature of the author. The PostScript language was a language to describe a page of text computationally. It was created by Adobe when Warnock, Doug Brotz, Charles Geschke, Bill Paxton (who worked on the Mother of All Demos with Doug Englebart during the development of Online System, or NLS in the late 70s and then at Xerox PARC), and Ed Taft.

    Warnock invented the Warnock algorithm while working on his PhD and went to work at Evans & Sutherland with Ivan Sutherland who effectively created the field of computer graphics. Geschke got his PhD at Carnegie Melon in the early 1970s and then went of to Xerox PARC. They worked with Paxton at PARC and before long, these PhDs and mathematicians had worked out the algorithms and then the languages to display images on computers while working on InterPress graphics at Xerox and Gerschke left Xerox and started Adobe. Warnock joined them and they went to market with Interpress as PostScript, which became a foundation for the Apple LaswerWriter to print graphics.  Not only that, PostScript could be used to define typefaces programmatically and later to display any old image. 
     
    Those technologies became the foundation for the desktop publishing industry. Apple released the 1984 Mac and other vendors brought in PostScript to describe graphics in their proprietary fashion and by 1991 they released PostScript Level 2 and then PostScript 3 in 1997. Other vendors made their own or furthered standards in their own ways and Adobe could have faded off into the history books of computing. But Adobe didn’t create one product, they created an industry and the company they created to support that young industry created more products in that mission. 

    Steve Jobs tried to buy Adobe before that first Mac as released, for $5,000,000. But Warnock and Geschke had a vision for an industry in mind. They had a lot of ideas but development was fairly capital intensive, as were go to market strategies. So they went public on the NASDAQ in 1986. They expanded their PostScript distribution and sold it to companies like Texas Instruments for their laser printer, and other companies who made IBM-compatible companies. They got up to $16 million in sales that year.

    Warnock’s wife was a graphic designer. This is where we see a diversity of ideas help us think about more than math. He saw how she worked and could see a world where Ivan Sutherland’s Sketchpad was much more given how far CPUs had come since the TX-0 days at MIT. So Adobe built and released Illustrator in 1987. By 1988 they broke even on sales and it raked in $19 million in revenue. Sales were strong in the universities but PostScript was still the hot product, selling to printer companies, typesetters, and other places were Adobe signed license agreements. 

    At this point, we see where the math, cartesian coordinates, drawn by geometric algorithms put pixels where they should be. But while this was far more efficient than just drawing a dot in a coordinate for larger images, drawing a dot in a pixel location was still the easier technology to understand. 

    They created Adobe Screenline in 1989 and Collectors Edition to create patterns. They listened to graphic designers and built what they heard humans wanted.

    Photoshop
    Nearly every graphic designer raves about Adobe Photoshop. That’s because Photoshop is the best selling graphics editorial tool that has matured far beyond most other traditional solutions and now has thousands of features that allow users to manipulate images in practically any way they want. 

    Adobe Illustrator was created in 1987 and quickly became the de facto standard in vector-based graphics. Photoshop began life in 1987 as well, when Thomas and John Knoll, wanted to build a simpler tool to create graphics on a computer. Rather than vector graphics they created a raster graphical editor. 

    They made a deal with Barneyscan, a well-known scanner company that managed to distribute over two hundred copies of Photoshop with their scanners and Photoshop became a hit as it was the first editing software people heard about. Vector images are typically generated with Cartesian coordinates based on geometric formulas and so scale out more easily. Raster images are comprised of a grid of dots, or pixels, and can be more realistic. 

    Great products are rewarded with competitions. CorelDRAW was created in 1989 when Michael Bouillon and Pat Beirne built a tool to create vector illustrations. The sales got slim after other competitors entered the market and the Knoll brothers got in touch with Adobe and licensed the product through them. The software was then launched as Adobe Photoshop 1 in 1990. They released Photoshop 2 in 1991. By now they had support for paths, and given that Adobe also made Illustrator, EPS and CMYK rasterization, still a feature in Photoshop. 

    They launched Adobe Photoshop 2.5 in 1993, the first version that could be installed on Windows. This version came with a toolbar for filters and 16-bit channel support. Photoshop 3 came in 1994 and Thomas Knoll created what was probably one of the most important features added, and one that’s become a standard in graphical applications since, layers. Now a designer could create a few layers that each had their own elements and hide layers or make layers more transparent. These could separate the subject from the background and led to entire new capabilities, like an almost faux 3 dimensional appearance of graphics.. 

    Then version four in 1996 and this was one of the more widely distributed versions and very stable. They added automation and this was later considered part of becoming a platform - open up a scripting language or subset of a language so others built tools that integrated with or sat on top of those of a product, thus locking people into using products once they automated tasks to increase human efficiency. 

    Adobe Photoshop 5.0 added editable type, or rasterized text. Keep in mind that Adobe owned technology like PostScript and so could bring technology from Illustrator to Photoshop or vice versa, and integrate with other products - like export to PDF by then. They also added a number of undo options, a magnetic lasso, improved color management and it was now a great tool for more advanced designers. Then in 5.5 they added a save for web feature in a sign of the times. They could created vector shapes and continued to improve the user interface.

    Adobe 5 was also a big jump in complexity. Layers were easy enough to understand, but Photoshop was meant to be a subset of Illustrator features and had become far more than that. So in 2001 they released Photoshop Elements. By now they had a large portfolio of products and Elements was meant to appeal to the original customer base - the ones who were beginners and maybe not professional designers. By now, some people spent 40 or more hours a day in tools like Photoshop and Illustrator. 

    Adobe Today
    Adobe had released PostScript, Illustrator, and Photoshop. But they have one of the most substantial portfolios of products of any company. They also released Premiere in 1991 to get into video editing. They acquired Aldus Corporation to get into more publishing workflows with PageMaker. They used that acquisition to get into motion graphics with After Effects. They acquired dozens of companies and released their products as well.

    Adobe also released the PDF format do describe full pages of information (or files that spread across multiple pages) in 1993 and Adobe Acrobat to use those. Acrobat became the de facto standard for page distribution so people didn’t have to download fonts to render pages properly. They dabbled in audio editing when they acquired Cool Edit Pro from Syntrillium Software and so now sell Adobe Audition. 

    Adobe’s biggest acquisition was Macromedia in 2005. Here, they added a dozen new products to the portfolio, which included Flash, Fireworks, WYSYWIG web editor Dreamweaver, ColdFusion, Flex, and Breeze, which is now called Adobe Connect. By now, they’d also created what we call Creative Suite, which are packages of applications that could be used for given tasks. Creative Suite also signaled a transition into a software as a service, or SaaS mindset. Now customers could pay a monthly fee for a user license rather than buy large software packages each time a new version was released.

    Adobe had always been a company who made products to create graphics. They expanded into online marketing and web analytics when they bought Omniture in 2009 for $1.8 billion. These products are now normalized into the naming convention used for the rest as Adobe Marketing Cloud. Flash fell by the wayside and so the next wave of acquisitions were for more mobile-oriented products. This began with Day Software and then Nitobi in 2011. And they furthered their Marketing Cloud support with an acquisition of one of the larger competitors when they acquired Marketo in 2018 and acquiring Workfront in 2020. 

    Given how many people started working from home, they also extended their offerings into pure-cloud video tooling with an acquisition of Frame.io in 2021. And here we see a company started by a bunch of true computer sciencists from academia in the early days of the personal computer that has become far more. They could have been rolled into Apple but had a vision of a creative suite of products that could be used to make the world a prettier place. Creative Suite then Creative Cloud shows a move of the same tools into a more online delivery model. Other companies come along to do similar tasks, like infinite digital whiteboard Miro - so they have to innovate to stay marketable. They have to continue to increase sales so they expand into other markets like the most adjacent Marketing Cloud. 

    At 22,500+ employees and with well over $12 billion in revenues, they have a lot of families dependent on maintaining that growth rate. And so the company becomes more than the culmination of their software. They become more than graphic design, web design, video editing, animation, and visual effects. Because in software, if revenues don’t grow at a rate greater than 10 percent per year, the company simply isn’t outgrowing the size of the market and likely won’t be able to justify stock prices at an inflated earnings to price ratio that shows explosive growth. And yet once a company saturates sales in a given market they have shareholders to justify their existence to. Adobe has survived many an economic downturn and boom time with smart, measured growth and is likely to continue doing so for a long time to come.

    The Evolution of Fonts on Computers

    The Evolution of Fonts on Computers

    Gutenburg shipped the first working printing press around 1450 and typeface was born. Before then most books were hand written, often in blackletter calligraphy. And they were expensive. 
     
    The next few decades saw Nicolas Jensen develop the Roman typeface, Aldus Manutius and Francesco Griffo create the first italic typeface. This represented a period where people were experimenting with making type that would save space.

    The 1700s saw the start of a focus on readability. William Caslon created the Old Style typeface in 1734. John Baskerville developed Transitional typefaces in 1757. And Firmin Didot and Giambattista Bodoni created two typefaces that would become the modern family of Serif. Then slab Serif, which we now call Antique, came in 1815 ushering in an era of experimenting with using type for larger formats, suitable for advertisements in various printed materials. These were necessary as more presses were printing more books and made possible by new levels of precision in the metal-casting.

    People started experimenting with various forms of typewriters in the mid-1860s and by the 1920s we got Frederic Goudy, the first real full-time type designer. Before him, it was part of a job. After him, it was a job. And we still use some of the typefaces he crafted, like Copperplate Gothic. And we saw an explosion of new fonts like Times New Roman in 1931.

    At the time, most typewriters used typefaces on the end of a metal shaft. Hit a kit, the shaft hammers onto a strip of ink and leaves a letter on the page. Kerning, or the space between characters, and letter placement were often there to reduce the chance that those metal hammers jammed. And replacing a font would have meant replacing tons of precision parts. Then came the IBM Selectric typewriter in 1961. Here we saw precision parts that put all those letters on a ball. Hit a key, the ball rotates and presses the ink onto the paper. And the ball could be replaced. A single document could now have multiple fonts without a ton of work.

    Xerox exploded that same year with the Xerox 914, one of the most successful products of all time. Now, we could type amazing documents with multiple fonts in the same document quickly - and photocopy them. And some of the numbers on those fancy documents were being spat out by those fancy computers, with their tubes. But as computers became transistorized heading into the 60s, it was only a matter of time before we put fonts on computer screens.

    Here, we initially used bitmaps to render letters onto a screen. By bitmap we mean that a series, or an array of pixels on a screen is a map of bits and where each should be displayed on a screen. We used to call these raster fonts, but the drawback was that to make characters bigger, we needed a whole new map of bits. To go to a bigger screen, we probably needed a whole new map of bits. As people thought about things like bold, underline, italics, guess what - also a new file. But through the 50s, transistor counts weren’t nearly high enough to do something different than bitmaps as they rendered very quickly and you know, displays weren’t very high quality so who could tell the difference anyways. 

    Whirlwind was the first computer to project real-time graphics on the screen and the characters were simple blocky letters. But as the resolution of screens and the speed of interactivity increased, so did what was possible with drawing glyphs on screens. 

    Rudolf Hell was a German, experimenting with using cathode ray tubes to project a CRT image onto paper that was photosensitive and thus print using CRT. He designed a simple font called Digital Grotesk, in 1968. It looked good on the CRT and the paper. And so that font would not only be used to digitize typesetting, loosely based on Neuzeit Book.

    And we quickly realized bitmaps weren’t efficient to draw fonts to screen and by 1974 moved to outline, or vector, fonts. Here a Bézier curve was drawn onto the screen using an algorithm that created the character, or glyph using an outline and then filling in the space between. These took up less memory and so drew on the screen faster. Those could be defined in an operating system, and were used not only to draw characters but also by some game designers to draw entire screens of information by defining a character as a block and so taking up less memory to do graphics. 

    These were scalable and by 1979 another German, Peter Karow, used spline algorithms wrote Ikarus, software that allowed a person to draw a shape on a screen and rasterize that. Now we could graphically create fonts that were scalable. 

    In the meantime, the team at Xerox PARC had been experimenting with different ways to send pages of content to the first laser printers. Bob Sproull and Bill Newman created the Press format for the Star. But this wasn’t incredibly flexible like what Karow would create. John Gaffney who was working with Ivan Sutherland at Evans & Sutherland, had been working with John Warnock on an interpreter that could pull information from a database of graphics. When he went to Xerox, he teamed up with Martin Newell to create J&M, which harnessed the latest chips to process graphics and character type onto printers. As it progressed, they renamed it to Interpress.

    Chuck Geschke started the Imaging Sciences Laboratory at Xerox PARC and eventually left Xerox with Warnock to start a company called Adobe in Warnock’s garage, which they named after a creek behind his house. Bill Paxton had worked on “The Mother of All Demos” with Doug Engelbart at Stanford, where he got his PhD and then moved to Xerox PARC. There he worked on bitmap displays, laser printers, and GUIs - and so he joined Adobe as a co-founder in 1983 and worked on the font algorithms and helped ship a page description language, along with Chuck Geschke, Doug Brotz, and Ed Taft. 

    Steve Jobs tried to buy Adobe in 1982 for $5 million. But instead they sold him just shy of 20% of the company and got a five-year license for PostScript. This allowed them to focus on making the PostScript language more extensible, and creating the Type 1 fonts. These had 2 parts. One that was a set of bit maps And another that was a font file that could be used to send the font to a device. 

    We see this time and time again. The simpler an interface and the more down-market the science gets, the faster we see innovative industries come out of the work done. There were lots of fonts by now. The original 1984 Mac saw Susan Kare work with Jobs and others to ship a bunch of fonts named after cities like Chicago and San Francisco. She would design the fonts on paper and then conjure up the hex (that’s hexadecimal) for graphics and fonts. She would then manually type the hexadecimal notation for each letter of each font. 

    Previously, custom fonts were reserved for high end marketing and industrial designers. Apple considered licensing existing fonts but decided to go their own route. She painstakingly created new fonts and gave them the names of towns along train stops around Philadelphia where she grew up. Steve Jobs went for the city approach but insisted they be cool cities. And so the Chicago, Monaco, New York, Cairo, Toronto, Venice, Geneva, and Los Angeles fonts were born - with her personally developing Geneva, Chicago, and Cairo. And she did it in 9 x 7. 

    I can still remember the magic of sitting down at a computer with a graphical interface for the first time. I remember opening MacPaint and changing between the fonts, marveling at the typefaces. I’d certainly seen different fonts in books. But never had I made a document and been able to set my own typeface! Not only that they could be in italics, outline, and bold. Those were all her. And she inspired a whole generation of innovation.

    Here, we see a clean line from Ivan Sutherland and the pioneering work done at MIT to the University of Utah to Stanford through the oNLine System (or NLS) to Xerox PARC and then to Apple. But with the rise of Windows and other graphical operating systems. As Apple’s 5 year license for PostScript came and went they started developing their own font standard as a competitor to Adobe, which they called TrueType.

    Here we saw Times Roman, Courier, and symbols that could replace the PostScript fonts and updating to Geneva, Monaco, and others. They may not have gotten along with Microsoft, but they licensed TrueType to them nonetheless to make sure it was more widely adopted. And in exchange they got a license for TrueImage, which was a page description language that was compatible with PostScript. Given how high resolution screens had gotten it was time for the birth of anti-aliasing. He we could clean up the blocky “jaggies” as the gamers call them. Vertical and horizontal lines in the 8-bit era looked fine but distorted at higher resolutions and so spatial anti-aliasing and then post-processing anti-aliasing was born.

    By the 90s, Adobe was looking for the answer to TrueImage. So 1993 brought us PDF, now an international standard in ISO 32000-1:2008. But PDF Reader and other tools were good to Adobe for many years, along with Illustrator and then Photoshop and then the other products in the Adobe portfolio. By this time, even though Steve Jobs was gone, Apple was hard at work on new font technology that resulted in Apple Advanced Typography, or AAT. AAT gave us ligature control, better kerning and the ability to write characters on different axes. 

    But even though Jobs was gone, negotiations between Apple and Microsoft broke down to license AAT to Microsoft. They were bitter competitors and Windows 95 wasn’t even out yet. So Microsoft started work on OpenType, their own font standardized language in 1994 and Adobe joined the project to ship the next generation in 1997. And that would evolve into an open standard by the mid-2000s. And once an open standard, sometimes the de facto standard as opposed to those that need to be licensed.

    By then the web had become a thing. Early browsers and the wars between them to increment features meant developers had to build and test on potentially 4 or 5 different computers and often be frustrated by the results. So the WC3 began standardizing how a lot of elements worked  in Extensible Markup Language, or XML. Images, layouts, colors, even fonts. SVGs are XML-based vector image. In other words the browser interprets a language that displays the image. That became a way to render

    Web Open Format or WOFF 1 was published in 2009 with contributions by Dutch educator Erik van Blokland, Jonathan Kew, and Tal Leming. This built on the CSS font styling rules that had shipped in Internet Explorer 4 and would slowly be added to every browser shipped, including Firefox since 3.6, Chrome since 6.0, Internet Explorer since 9, and Apple’s Safari since 5.1. Then WOFF 2 added Brotli compression to get sizes down and render faster. WOFF has been a part of the W3C open web standard since 2011. 

    Out of Apple’s TrueType came TrueType GX, which added variable fonts. Here, a single font file could contain a number or range of variants to the initial font. So a family of fonts could be in a single file. OpenType added variable fonts in 2016, with Apple, Microsoft, and Google all announcing support. And of course the company that had been there since the beginning, Adobe, jumped on board as well. Fewer font files, faster page loads. 

    So here we’ve looked at the progression of fonts from the printing press, becoming more efficient to conserve paper, through the advent of the electronic typewriter to the early bitmap fonts for screens to the vectorization led by Adobe into the Mac then Windows. We also see rethinking the font entirely so multiple scripts and character sets and axes can be represented and rendered efficiently. 

    I am now converting all my user names into pig Latin for maximum security. Luckily those are character sets that are pretty widely supported. The ability to add color to pig Latin means that OpenType-SVG will allow me add spiffy color to my glyphs. It makes us wonder what’s next for fonts. Maybe being able to design our own, or more to the point, customize those developed by others to make them our own. We didn’t touch on emoji yet. But we’ll just have to save the evolution of character sets and emoji for another day.

    In the meantime, let’s think on the fact that fonts are such a big deal because Steve Jobs took a caligraphy class from a Trappist monk named Robert Palladino while enrolled at Reed College. Today we can painstakingly choose just the right font with just the right meaning because Palladino left the monastic life to marry and have a son. He taught jobs about serif and san serif and kerning and the art of typography. 

    That style and attention to detail was one aspect of the original Mac that taught the world that computers could have style and grace as well. It’s not hard to imagine if entire computers still only supported one font or even one font per document. Palladino never owned or used a computer though. His influence can be felt through the influence his pupil Jobs had. And it’s actually amazing how many people who had such dramatic impacts on computing never really used one. Because so many smaller evolutions came after them. What evolutions do we see on the horizon today? And how many who put a snippet of code on a service like GitHub may never know the impact they have on so many?

    Flight Part II: From Balloons to Autopilot to Drones

    In our previous episode, we looked at the history of flight - from dinosaurs to the modern aircraft that carry people and things all over the world. Those helped to make the world smaller, but UAVs and drones have had a very different impact in how we lead our lives - and will have an even more substantial impact in the future. That might not have seemed so likely in the 1700s, though - when unmann

    Napoleon conquered Venice in 1797 and then ceded control to the Austrians the same year. He then took it as part of a treaty in 1805 and established the first Kingdom of Italy. Then lost it in 1814. And so they revolted in 1848. One of the ways the Austrians crushed the revolt, in part employing balloons, which had been invented in 1783, that were packed with explosives. 200 balloons packed with bombs later, one found a target. Not a huge surprise that such techniques didn’t get used again for some time. The Japanese tried a similar tactic to bomb the US in World War II - then there were random balloons in the 2020s, just for funsies.

    A few other inventions needed to find one another in order to evolve into something entirely new. Radio was invented in the 1890s. Nikola Tesla built a radio controlled boat in 1898. Airplanes came along in 1903. Then came airships moved by radio. So it was just a matter of time before the cost of radio equipment came down enough to match the cost of building smaller airplanes that could be controlled with remote controls as well. 

    The first documented occurrence of that was in 1907 when Percy Sperry filed a patent for a kite fashioned to look and operate like a plane, but glide in the wind. The kite string was the first remote control. Then electrical signals went through those strings and eventually the wire turned into radio - the same progress we see with most manual machinery that needs to be mobile.

    Technology moves upmarket, so Sperry Corporation the aircraft with autopilot features in 1912. At this point, that was just a gyroscopic heading indicator and attitude indicator that had been connected to hydraulically operated elevators and rudders but over time would be able to react to all types of environmental changes to save pilots from having to constantly manually react while flying. That helped to pave the way for longer and safer flights, as automation often does.

    Then came World War I. Tesla discussed aerial combat using unmanned aircraft in 1915 and Charles Kettering (who developed the electric cash register and the electric car starter) gave us The Kettering Bug, a flying, remote controlled torpedo of sorts. Elmer Sperry worked on a similar device. British war engineers like Archibald Low were also working on attempts but the technology didn’t evolve fast enough and by the end of the war there wasn’t much interest in military funding.

    But a couple of decades can do a lot. Both for miniaturization and maturity of technology. 1936 saw the development of the first navy UAV aircraft by the name of Queen Bee by Admiral William H. Stanley then the QF2. They was primarily used for aerial target practice as a low-cost radio-controlled drone. The idea was an instant hit and later on, the military called for the development of similar systems, many of which came from Hollywood of all places.

    Reginald Denny was a British gunner in World War I. They shot things from airplanes. After the war he moved to Hollywood to be an actor. By the 1930s he got interested in model airplanes that could fly and joined up with Paul Whittier to open a chain of hobby shops. He designed a few planes and eventually grew them to be sold to the US military as targets. The Radioplane as they would be known even got joysticks and they sold tens of thousands during World War II. 

    War wasn’t the only use for UAVs. Others were experimenting and by 1936 we got the first radio controlled model airplane competition in 1936, a movement that continued to grow and evolve into the 1970s. We got the Academy of Model Aeronautics (or AMA) in 1936, who launched a magazine called Model Aviation and continues to publish, provide insurance, and act as the UAV, RC airplane, and drone community representative to the FAA. Their membership still runs close to 200,000.

    Most of these model planes were managed from the ground using radio remote controls. 
    The Federal Communications Commission, or FCC, was established in 1934 to manage the airwaves. They stepped in to manage what frequencies could be used for different use cases in the US, including radio controlled planes.

    Where there is activity, there are stars. The Big Guff, built by brothers Walt and Bill Guff, was the first truly successful RC airplane in that hobbiest market. Over the next decades solid state electronics got smaller, cheaper, and more practical. As did the way we could transmit bits over those wireless links. 

    1947 saw the first radar-guided missile, the subsonic Firebird, which over time evolved into a number of programs. Electro-mechanical computers had been used to calculate trajectories for ordinances during World War II so with knowledge of infrared, we got infrared homing then television cameras mounted into missiles and when combined with the proximity fuse, which came with small pressure, magnetic, acoustic, radio, then optical transmitters. We got much better at blowing things up. 

    Part of that was studying the German V-2 rocket programs. They used an analog computer to control the direction and altitude of missiles. The US Polaris and Minuteman missile programs added transistors then microchips to missiles to control the guidance systems. Rockets had computers and so they showed up in airplanes to aid humans in guiding those, often replacing Sperry’s original gyroscopic automations. The Apollo Guidance Computer from the 1969 moon landing was an early example of times when humans even put their lives in the hands of computers - with manual override capabilities of course. Then as the price of chips fell in the 1980s we started to see them in model airplanes.

    Modern Drones
    By now, radio controlled aircraft had been used for target practice, to deliver payloads and blow things up, and even for spying. Aircraft without humans to weight them down could run on electric motors rather than combustable engines. Thus they were quieter. This technology allowed the UAVs to fly undetected thus laying the very foundation for the modern depiction of drones used by the military for covert operations. 

    As the costs fell and carrying capacity increased, we saw them used in filmmaking, surveying, weather monitoring, and anywhere else a hobbyist could use their hobby in their career. But the cameras weren’t that great yet. Then Fairchild developed the charge-coupled device, or CCD, in 1969. The first digital camera arguably came out of Eastman Kodak in 1975 when Steven Sasson built a prototype using a mixture of batteries, movie camera lenses, Fairchild CCD sensors, and Motorola parts. Sony came out with the Magnetic Video Camera in 1981 and Canon put the RC701 on the market in 1986. Fuji, Dycam, even the Apple QuickTake, came out in the next few years. Cameras were getting better resolution, and as we turned the page into the 1990s, those cameras got smaller and used CompactFlash to store images and video files.

    The first aerial photograph is attributed to Gaspar Tournachon, but the militaries of the world used UAVs that were B-17 and Grumman Hellcats from World War II that had been converted to drones full of sensors to study nuclear radiation clouds when testing weapons. Those evolved into Reconnaisance drones like the Aerojet SD-2, with mounted analog cameras in the 50s and 60s. During that time we saw the Ryan Firebees and DC-130As run thousands of flights snapping photos to aid intelligence gathering.

    Every country was in on it. The USSR, Iran, North Korea, Britain. And the DARPA-instigated Amber and then Predator drones might be considered the modern precursor to drones we play with today. Again, we see the larger military uses come down market once secrecy and cost meet a cool factor down-market. DARPA spent $40 million on the Amber program. Manufacturers of consumer drones have certainly made far more than that. 

    Hobbyists started to develop Do It Yourself (DIY) drone kits in the early 2000s. Now that there were websites, we didn’t have to wait for magazines to show up, we could take to the World Wide Web forums and trade ideas for how to do what the US CIA had done when they conducted the first armed drone strike in 2001 - just maybe without the weapon systems since this was in the back yard. 

    Lithium-ion batteries were getting cheaper and lighter. As were much faster chips. Robotics had come a long way as well, and moving small parts of model aircraft was much simpler than avoiding all the chairs in a room at Stanford. Hobbyists turned into companies that built and sold drones of all sizes, some of which got in the way of commercial aircraft. So the FAA started issuing drone permits in 2006. 

    Every technology had a point, where the confluence of all these technologies meets into a truly commercially viable product. We had Wi-Fi, RF (or radio frequency), iPhones, mobile apps, tiny digital cameras in our phones, and even in spy teddy bears, we understood flight, propellers, plastics were heavier-than-air, but lighter than metal. So in 2010 we got the Parrot AR Drone. This was the first drone that was sold to the masses that was just plug and play. And an explosion of drone makers followed, with consumer products ranging from around $20 to hundreds now. Drone races, drone aerogymnastics, drone footage on our Apple and Google TV screens, and with TinyML projects for every possible machine learning need we can imagine, UAVs that stabilize cameras, can find objects based on information we program into it, and any other use we can imagine. 

    The concept of drones or unmanned aerial vehicles (UAV) has come a long way since the Austrians tried to bomb the Venetians into submission. Today  there are mini drones, foldable drones, massive drones that can carry packages, racing drones, and even military drones programmed to kill. In fact, right now there are debates raging in the UN around whether to allow drones to autonomously kill. Because Skynet. 

    We’re also experimenting with passenger drone technology. Because autonomous driving is another convergence just waiting in the wings. Imagine going to the top of a building and getting in a small pod then flying a few buildings over - or to the next city. Maybe in our lifetimes, but not as soon as some of the companies who have gone public to do just this thought. 

    Flight: From Dinosaurs to Space

    Flight: From Dinosaurs to Space

    Humans have probably considered flight since they found birds. As far as 228 million years ago, the Pterosaurs used flight to reign down onto other animals from above and eat them. The first known bird-like dinosaur was the Archaeopteryx, which lived around 150 million years ago. It’s not considered an ancestor of modern birds - but other dinosaurs from the same era, the theropods, are. 25 million years later, in modern China, the Confuciusornis sanctus had feathers and could have flown. The first humans wouldn’t emerge from Africa until 23 million years later. By the 2300s BCE, the Summerians depicted shepherds riding eagles, as humanity looked to the skies in our myths and legends. These were creatures, not vehicles.

    The first documented vehicle of flight was as far back as the 7th century BCE when the Rāmāyana told of the Pushpaka Vimāna, a palace made by Vishwakarma for Brahma, complete with chariots that flew the king Rama high into the atmosphere. The Odyssey was written around the same time and tells of the Greek pantheon of Gods but doesn’t reference flight as we think of it today. Modern interpretations might move floating islands to the sky, but it seems more likely that the floating island of Aeollia is really the islands off Aeolis, or Anatolia, which we might refer to as the modern land of Turkey. 

    Greek myths from a few hundred years later introduced more who were capable of flight. Icarus flew into the sun with wings that had been fashioned by Daedalus. By then, they could have been aware, through trade routes cut by Alexander and later rulers, of kites from China. The earliest attempts at flight trace their known origins to 500 BCE in China. Kites were, like most physical objects, heavier than air and could still be used to lift an object into flight. Some of those early records even mention the ability to lift humans off the ground with a kite. The principle used in kites was used later in the development of gliders and then when propulsion was added, modern aircraft. Any connection between any of these is conjecture as we can’t know how well the whisper net worked in those ages.

    Many legends are based on real events. The history of humanity is vast and many of our myths are handed down through the generations. The Greeks had far more advanced engineering capabilities than some of the societies that came after. They were still weary of what happened if they flew too close to the sun. In fact, emperors of China are reported to have forced some to leap from cliffs on a glider as a means of punishment. Perhaps that was where the fear of flight for some originated from. Chinese emperor Wang Mang used a scout with bird features to glide on a scouting mission around the same time as the Icarus myth might have been documented. Whether this knowledge informed the storytellers Ovid documented in his story of Icarus is lost to history, since he didn’t post it to Twitter.

    Once the Chinese took the string off the kite and they got large enough to fly with a human, they had also developed hang gliders. In the third century BCE, Chinese inventors added the concept of rotors for vertical flight  when they developed helicopter-style toys. Those were then used to frighten off enemies. Some of those evolved into the beautiful paper lanterns that fly when lit.There were plenty of other evolutions and false starts with flight after that. Abbas ibn Ferns also glided with feathers in the 9th century. A Benedictine monk did so again in the 11th century. Both were injured when they jumped out of towers in the Middle Ages that spanned the Muslim Golden Age to England. 

    Leonardo da Vinci studied flight for much of his life. His studies produced another human-power ornithopter and other contraptions; however he eventually realized that humans would not be able to fly on their own power alone. Others attempted the same old wings made of bird feathers, wings that flapped on the arms, wings tied to legs, different types of feathers, finding higher places to jump from, and anything they could think of. Many broke bones, which continued until we found ways to supplement human power to propel us into the air. Then a pair of brothers in the Ottoman Empire had some of the best luck. Hezarafen Ahmed Çelebi crossed the Bosphorus strait on a glider. That was 1633, and by then gunpowder already helped the Ottomans conquer Constantinople. That ended the last vestiges of ancient Roman influence along with the Byzantine empire as the conquerers renamed the city to Instanbul. That was the power of gunpowder. His brother then built a rocket using gunpowder and launched himself high in the air, before he glided back to the ground. 

    The next major step was the hot air balloon. The modern hot air balloon was built by the Montgolfier brothers in France and first ridden in 1783 and (Petrescu & Petrescu, 2013). 10 days later, the first gas balloon was invented by Nicholas Louis Robert and Jacques Alexander Charles. The gas balloon used hydrogen and in 1785, used to cross the English Channel. That trip sparked the era of dirigibles. We built larger balloons to lift engines with propellers. That began a period that culminated with the Zeppelin. From the 1700s and on, much of what da Vinci realized was rediscovered, but this time published, and the body of knowledge built out. The physics of flight were then studied as new sciences emerged. Sir George Cayley started to actually apply physics to flight in the 1790s. 

    Powered Flight
    We see this over and over in history; once we understand the physics and can apply science, progress starts to speed up. That was true when Archimedes defined force multipliers with the simple machines in the 3rd century BCE, true with solid state electronics far later, and true with Cayley’s research. Cayley conducted experiments, documented his results, and proved hypotheses. He finally got to codifying bird flight and why it worked. He studied the Chinese tops that worked like modern helicopters. He documented glided flight and applied math to why it worked. He defined drag and measured the force of windmill blades. In effect, he got to the point that he knew how much power was required based on the ratio of weight to actually sustain flight. Then to achieve that, he explored the physics of fixed-wing aircraft, complete with an engine, tail assembly, and fuel. His work culminated in a work called “On Aerial Navigation” that was published in 1810. 

    By the mid-1850s, there was plenty of research that flowed into the goal for sustained air travel. Ideas like rotors led to rotor crafts. Those were all still gliding. Even with Cayley’s research, we had triplane gliders, gliders launched from balloons. After that, the first aircrafts that looked like the modern airplanes we think of today were developed. Cayley’s contributions were profound. He even described how to mix air with gasoline to build an engine. Influenced by his work, others built propellers. Some of those were steam powered and others powered by tight springs, like clockworks. Aeronautical societies were created, wing counters and cambering were experimented with, and wheels were added to try to lift off. Some even lifted a little off the ground. By the 1890s, the first gasoline powered biplane gliders were developed and flown, even if those early experiments crashed. Humanity was finally ready for powered flight.

    The Smithsonian housed some of the earliest experiments. They hired their third director, Samuel Langley, in 1887. He had been interested in aircraft for decades and as with many others had studied the Cayley work closely. He was a consummate tinkerer and had already worked in solar physics and developed the Allegheny Time System. The United States War department gave him grants to pursue his ideas to build an airplane. By then, there was enough science that humanity knew it was possible to fly and so there was a race to build powered aircraft. We knew the concepts of drag, rudders, thrust from some of the engineering built into ships. Some of that had been successfully used in the motorcar. We also knew how to build steam engines, which is what he used in his craft. He called it the Aerodrome and built a number of models. He was able to make it further than anyone at the time. He abandoned flight in 1903 when someone beat him to the finish line. 

    That’s the year humans stepped beyond gliding and into the first controlled, sustained, and powered flight. There are reports that Gustave Whitehead beat the Wright Brothers, but he didn’t keep detailed notes or logs, and so the Wrights are often credited with the discovery. They managed to solve the problem of how to roll, built steerable rudders, and built the first biplane with an internal combustion engine. They flew their first airplane out of North Carolina when Orville Wright went 120 feet and his brother went 852 feet later that day. That plane now lives at the National Air and Space Museum in Washington DC and December 17th, 1903 represents the start of the age of flight.

    The Wright’s spent two years testing gliders and managed to document their results. They studied in wind tunnels, tinkered with engines, and were methodical if not scientific in their approach. They didn’t manage to have a public demonstration until 1908 though and so there was a lengthy battle over the patents they filed. Turns out it was a race and there were a lot of people who flew within months of one another. Decades of research culminated into what had to be: airplanes. Innovation happened quickly. Flight improved enough that planes could cross English Channel by 1909. There were advances after that, but patent wars over the invention drug on and so investors stayed away from the unproven technology. 

    Flight for the Masses
    The superpowers of the world were at odds for the first half of the 1900s. An Italian pilot flew a reconnaissance mission in Libya in the Italo-Turkish war in 1911. It took only 9 days before they went from just reconnaissance and dropped grenades on Turkish troops from the planes. The age of aerial warfare had begun. The Wrights had received an order for the first plane from the military back in 1908. Military powers took note and by World War I there was an air arm of every military power. Intelligence wins wars. The innovation was ready for the assembly lines, so during and after the war, the first airplane manufacturers were born.

    Dutch engineer Anthony Fokker was inspired by Wilbur Wright’s exhibition in 1908. He went on to start a company and design the Fokker M.5, which evolved into the Fokker E.I. after World War I broke out in 1914. They mounted a machine gun and synchronized it to the  propeller in 1915. Manfred von Richthofen, also known as the Red Baron, flew one before he upgraded to the Fokker D.VII and later an Albatros. Fokker made it all the way into the 1990s before they went bankrupt. Albatros was founded in 1909 by Enno Huth, who went on to found the German Air Force before the war.

    The Bristol Aeroplane Company was born in 1910 after Sir George White, who was involved in transportation already, met Wilbur Wright in France. Previous companies were built to help hobbyists, similar to how many early PC companies came from inventors as well. This can be seen with people like Maurice Mallet, who helped design gas balloons and dirigibles. He licensed airplane designs to Bristol who later brought in Frank Barnwell and other engineers that helped design the Scout. They based the Bristol Fighters that were used in World War I on those designs. Another British manufacturer was Sopwith, started by Thomas Sopwith, who taught himself to fly and then started a company to make planes. They built over 16,000 by the end of the war. After the war they pivoted to make ABC motorcycles and eventually sold to Hawker Aircraft in 1920, which later sold to Raytheon. 

    The same paradigm played out elsewhere in the world, including the United States. Once those patent disputes were settled, plenty knew flight would help change the world. By 1917 the patent wars in the US had to end as the countries contributions to flight suffered. No investor wanted to touch the space and so there was a lack of capital to expand. Orville Write passed away in 1912 and Wilbur sold his rights to the patents, so the Assistant Secretary of the Navy, Franklin D. Roosevelt, stepped in and brought all the parties to the table to develop a cross-licensing organization. After almost 25 years, we could finally get innovation in flight back on track globally. In rapid succession, Loughead Aircraft, Lockheed, and Douglas Aircraft were founded. Then Jack Northrop left those and started his own aircraft company. Boeing was founded in 1957 as Aero Products and then United Aircraft, which was spun off into United Airlines as a carrier in the 1930s with Boeing continuing to make planes.

    United was only one of many a commercial airline that was created. Passenger air travel started after the first air flights with the first airline ferrying passengers in 1914. With plenty of airplanes assembled at all these companies, commercial travel was bound to explode into its own big business. Delta started as a cropdusting service in Macon, Georgia in 1925 and has grown into an empire. The worlds largest airline at the time of this writing is American Airlines, which started in 1926 when a number of smaller airlines banded together. Practically every country had at least one airline. Pan American (Panam for short) in 1927, Ryan Air started in 1926, Slow-Air in 1924, Finnair in 1923, Quantus in 1920, KLM in 1919, and the list goes on. Enough that the US passed the Air Commerce Act in 1926, which over time led to the department of Air Commerce, which evolved into the Federal Aviation Administration, or FAA we know today.

    Aircrafts were refined and made more functional. World War I brought with it the age of aerial combat. Plenty of supply after the war and then the growth of manufacturers Brough further innovation to compete with one another, and commercial aircraft and industrial uses (like cropdusting) enabled more investment into R&D

    In 1926, the first flying boat service was inaugurated from New York to Argentina. Another significant development in aviation was in the 1930s when the jet engine was invented. This invention was done by Frank Whittle who registered a turbojet engine patent. A jet plane was also developed by Hans von Ohain and was called the Heinkel He 178 (Grant, 2017).  The plane first flew in 1939, but the Whittle jet engine is the ancestor of those found in planes in World War II and beyond. And from there to the monster airliners and stealth fighters or X-15 becomes a much larger story. The aerospace industry continued to innovate both in the skies and into space. 

    The history of flight entered another phase in the Cold War. Rand corporation developed the concept of Intercontinental Ballistic Missiles (or ICBMs) and the Soviet Union launched the first satellite into space in 1957.  Then in 1969, Neil Armstrong and Buzz Aldrin made the first landing on the moon and we continued to launch into space throughout the 1970s to 1990s, before opening up space travel to private industry. Those projects got bigger and bigger and bigger. But generations of enthusiasts and engineers were inspired by devices far smaller, and without pilots in the device.

    SABRE and the Travel Global Distribution System

    SABRE and the Travel Global Distribution System

    Computing has totally changed how people buy and experience travel. That process seemed to start with sites that made it easy to book travel, but as with most things we experience in our modern lives, it actually began far sooner and moved down-market as generations of computing led to more consumer options for desktops, the internet, and the convergence of these technologies. Systems like SABRE did the original work to re-think travel - to take logic and rules out of the heads of booking and travel agents and put them into a digital medium. In so doing, they paved the way for future generations of technology and to this day retain a valuation of over $2 billion.
     
    SABRE is short for Semi-Automated Business Research Environment. It’s used to manage over a third of global travel, to the tune of over a quarter trillion US dollars a year. It’s used by travel agencies and travel services to reserve car rentals, flights, hotel rooms, and tours. Since Sabre was released services like Amadeus and Travelport were created to give the world a Global Distribution System, or GDS. 
     
    Passenger air travel began when airlines ferrying passengers cropped up in 1914 but the big companies began in the 1920s, with KLM in 1919, Finnair in 1923, Delta in 1925, American Airlines and Ryan Air in 1926,  Pan American in 1927, and the list goes on. They grew quickly and by 1926 the Air Commerce Act led to a new department in the government called Air Commerce, which evolved into the FAA, or Federal Aviation Administration in the US. And each country, given the possible dangers these aircraft posed as they got bigger and loaded with more and more fuel, also had their own such departments. The aviation industry blossomed in the roaring 20s as people traveled and found romance and vacation. At the time, most airlines were somewhat regional and people found travel agents to help them along their journey to book travel, lodgings, and often food. The travel agent naturally took over air travel much as they’d handled sea travel before. 

    But there were dangers in traveling in those years between the two World Wars. Nazis rising to power in Germany, Mussolini in Italy, communist cleansings in Russia and China. Yet, a trip to the Great Pyramid of Giza could now be a week instead of months. Following World War II, there was a fracture in the world between Eastern and Western powers, or those who aligned with the former British empire and those who aligned with the former Russian empire, now known as the Soviet Union. Travel within the West exploded as those areas were usually safe and often happy to accept the US dollar. Commercial air travel boomed not just for the wealthy, but for all. People had their own phones now, and could look up a phone number in a phone book and call a travel agent. 

    The travel agents then spent hours trying to build the right travel package. That meant time on the phone with hotels and time on the phone with airlines. Airlines like American head. To hire larger and larger call centers of humans to help find flights. We didn’t just read about Paris, we wanted to go. Wars had connected the world and now people wanted to visit the places they’d previously just seen in art books or read about in history books. But those call centers grew. A company like American Airlines couldn’t handle all of its ticketing needs and the story goes that the CEO was sitting beside a seller from IBM when they came up with the idea of a computerized reservation system.

    And so SABRE was born in the 1950s, when American  Airlines agreed to develop a real-time computing platform. Here, we see people calling in and pressing buttons to run commands on computers. The tones weren’t that different than a punch card, really. The system worked well enough for American that they decided to sell access to other firms. The computers used were based loosely after the IBM mainframes used in the SAGE missile air defense system. Here we see the commercial impacts of the AN/FSQ-7 the US government hired IBM to build as IBM added the transistorized options to the IBM 704 mainframe in 1955. That gave IBM the interactive computing technology that evolved into the 7000 series mainframes. 

    Now that IBM had the interactive technology, and a thorough study had been done to evaluate the costs and impacts of a new reservation system, American and IBM signed a contract to build the system in 1957. They went live to test reservation booking shortly thereafter. But it turns out there was a much bigger opportunity here. See, American and other airlines had paper processes to track how many people were on a flight and quickly find open seats for passengers, but it could take an hour or three to book tickets. This was fairly common before software ate the world. Everything from standing in line at the bank, booking dinner at a restaurant, reserving a rental car, booking hotel rooms, and the list goes on. 

    There were a lot of manual processes in the world - people weren’t just going to punch holes in a card to program their own flight and wait for some drum storage to tell them if there was an available seat. That was the plan American initially had in 1952 with the Magnetronic Reservisor. That never worked out. American had grown to one of the largest airlines and knew the perils and costs of developing software and hardware like this. Their system cost $40 million in 1950s money to build with IBM. They also knew that as other airlines grew to accommodate more people flying around the world, that the more flights, the longer that hour or three took. So they should of course sell the solution they built to other airlines. 

    Thus, parlaying the SAGE name, famous as a Cold War shield against the nuclear winter, Sabre Corporation began. It was fairly simple at first, with a pair of IBM 7090 mainframes that could take over 80,000 calls a day in 1960. Some travel agents weren’t fans of the new system, but those who embraced it found they could get more done in less time. Sabre sold reservation systems to airlines and soon expanded to become the largest data-processor in the world. Far better than the Reservisor would have been and now able to help bring the whole world into the age of jet airplane travel.

    That exploded to thousands of flights an hour in the 1960s and even turned over all booking to the computer. The system got busy and over the years IBM upgraded the computers to the S/360. They also began to lease systems to travel agencies in the 1970s after Max Hopper joined the company and began the plan to open up the platform as TWA had done with their PARS system. Then they went international, opened service bureaus in other cities (given that we once had to pay for a toll charge to call a number). And by the 1980s Sabre was how the travel agents booked flights. The 1980s brought easysabjre, so people could use their own computers to book flights and by then - and through to the modern era, a little over a third of all reservations are made on Sabre.

    By the mid-1980s, United had their own system called Apollo, Delta had one called Datas, and other airlines had their own as well. But SABRE could be made to be airline neutral. IBM had been involved with many American competitors, developing Deltamatic for Delta, PANAMAC for Pan Am, and other systems. But SABRE could be hooked to thee new online services for a whole new way to connect systems. One of these was CompuServe in 1980, then Prodigy’s GEnie and AOL as we turned the corner into the 1990s. Then they started a site called Travelocity in 1996 which was later sold to Expedia. 

    In the meantime, they got serious competition, which eventually led to a slew of acquisitions to remain compeititve. The competition included Amadeus, Galileo International, and Worldspan on provider in the Travelport GDS. The first of them originated from United Airlines, and by 1987 was joined by Aer Lingus, Air Portugal, Alitalia, British Airways, KLM, Olympic, Sabena, and Swissair to create Galileo, which was then merged with the Apollo reservation system. The technology was acquired through a company called Videcom International, which initially started developing reservation software in 1972, shortly after the Apollo and Datas services went online. They focused on travel agents and branched out into reservation systems of all sorts in the 1980s. As other systems arose they provided an aggregation to them by connecting to Amadeus, Galileo, and Worldspan.

    Amadeus was created in 1987 to be a neutral GDS after the issues with Sabre directing reservations to American Airlines. That was through a consortium of Air France, Iberia, Lufthansa, and SAS. They acquired the assets of the bankrupt System One and they eventually added other travel options including hotels, cars rentals, travel insurance, and other amenities. They went public in 1999 just before Sabre did and then were also taken private just before Sabre was. 

    Worldspan was created in 1990 and the result of merging or interconnecting the systems of  Delta, Northwest Airlines, and TWA, which was then acquired by Travelport in 2007. By then, SABRE had their own programming languages. While the original Sabre languages were written in assembly, they wrote their own language on top of C and C++ called SabreTalk and later transitioned to standard REST endpoints. They also weren’t a part of American any longer. There were too many problems with manipulating how flights were displayed to benefit American Airlines and they had to make a clean cut. Especially after Congress got involved in the 1980s and outlawed that type of bias for screen placement. 

    Now that they were a standalone company, Sabre went public then was taken private by private equity firms in 2007, and relisted on NASDAQ in 2014. Meanwhile, travel aggregators had figured out they could hook into the GDS systems and sell discount airfare without a percentage going to travel agents. Now that the GDS systems weren’t a part of the airlines, they were able to put downward pressure on prices. Hotwire, which used Sabre and a couple of other systems, and TripAdvisor, which booked travel through Sabre and Amadeus, were created in 2000 and Microsoft launched Expedia in 1996, which had done well enough to get spun off into its own public company by 2000. Travelocity operated inside Sabre until sold, and so the airlines put together a site of their own that they called Orbitz, which in 2001 was the biggest e-commerce site to have ever launched. And out of the bursting of the dot com bubble came online travel bookings. Kayak came in 2004

    Sabre later sold Travelocity to Expedia, which uses Sabre to book travel. That allowed Sabre to focus on providing the back end travel technology. They now do over $4 billion in revenue in their industry. American Express had handled travel for decades but also added flights and hotels to their site, integrating with Sabre and Amadeus as well. 

    Here, we see a classic paradigm in play. First the airlines moved their travel bookings from paper filing systems to isolated computer systems - what we’d call mainframes today. The airlines then rethink the paradigm and aggregate other information into a single system, or a system intermixed with other data. In short, they enriched the data. Then we expose those as APIs to further remove human labor and put systems on assembly lines. Sites hook into those and the GDS systems, as with many aggregators, get spun off into their own companies. The aggregated information then benefits consumers (in this case travelers) with more options and cheaper fares. This helps counteract the centralization of the market where airlines acquire other airlines but in some way also cheapen the experience. Gone are the days when a travel agent guides us through our budgets and helps us build a killer itinerary. But in a way that just makes travel much more adventurous. 

     

     

     

     

     

    The Story of Intel

    The Story of Intel

    We’ve talked about the history of microchips, transistors, and other chip makers. Today we’re going to talk about Intel in a little more detail. 

    Intel is short for Integrated Electronics. They were founded in 1968 by Robert Noyce and Gordon Moore. Noyce was an Iowa kid who went off to MIT to get a PhD in physics in 1953. He went off to join the Shockley Semiconductor Lab to join up with William Shockley who’d developed the transistor as a means of bringing a solid-state alternative to vacuum tubes in computers and amplifiers.

    Shockley became erratic after he won the Nobel Prize and 8 of the researchers left, now known as the “traitorous eight.”  Between them came over 60 companies, including Intel - but first they went on to create a new company called Fairchild Semiconductor where Noyce invented the monolithic integrated circuit in 1959, or a single chip that contains multiple transistors. 

    After 10 years at Fairchild, Noyce joined up with coworker and fellow traitor Gordon Moore. Moore had gotten his PhD in chemistry from Caltech and had made an observation while at Fairchild that the number of transistors, resistors, diodes, or capacitors in an integrated circuit was doubling every year and so coined Moore’s Law, that it would continue to to do so. They wanted to make semiconductor memory cheaper and more practical.

    They needed money to continue their research. Arthur Rock had helped them find a home at Fairchild when they left Shockley and helped them raise $2.5 million in backing in a couple of days. 

    The first day of the company, Andy Grove joined them from Fairchild. He’d fled the Hungarian revolution in the 50s and gotten a PhD in chemical engineering at the University of California, Berkeley. Then came Leslie Vadász, another Hungarian emigrant. Funding and money coming in from sales allowed them to hire some of the best in the business. People like Ted Hoff , Federico Faggin, and Stan Mazor.

    That first year they released 64-bit static random-access memory in the 3101 chip, doubling what was on the market as well as the 3301 read-only memory chip, and the 1101. Then DRAM, or dynamic random-access memory in the 1103 in 1970, which became the bestselling chip within the first couple of years.

    Armed with a lineup of chips and an explosion of companies that wanted to buy the chips, they went public within 2 years of being founded. 1971 saw Dov Frohman develop erasable programmable read-only memory, or EPROM, while working on a different problem. This meant they could reprogram chips using ultraviolet light and electricity.

    In 1971 they also created the Intel 4004 chip, which was started in 1969 when a calculator manufacturer out of Japan ask them to develop 12 different chips. Instead they made one that could do all of the tasks of the 12, outperforming the ENIAC from 1946 and so the era of the microprocessor was born. And instead of taking up a basement at a university lab, it took up an eight of an inch by a sixth of an inch to hold a whopping 2,300 transistors. The chip didn’t contribute a ton to the bottom line of the company, but they’d built the first true microprocessor, which would eventually be what they were known for.

    Instead they were making DRAM chips. But then came the 8008 in 1972, ushering in an 8-bit CPU. The memory chips were being used by other companies developing their own processors but they knew how and the Computer Terminal Corporation was looking to develop what was a trend for a hot minute, called programmable terminals. And given the doubling of speeds those gave way to microcomputers within just a few years.

    The Intel 8080 was a 2 MHz chip that became the basis of the Altair 8800, SOL-20, and IMSAI 8080. By then Motorola, Zilog, and MOS Technology were hot on their heals releasing the Z80 and 6802 processors. But Gary Kildall wrote CP/M, one of the first operating systems, initially for the 8080 prior to porting it to other chips.

    Sales had been good and Intel had been growing. By 1979 they saw the future was in chips and opened a new office in Haifa, Israiel, where they designed the 8088, which clocked in at 4.77 MHz. IBM chose this chip to be used in the original IBM Personal Computer. IBM was going to use an 8-bit chip, but the team at Microsoft talked them into going with the 16-bit 8088 and thus created the foundation of what would become the Wintel or Intel architecture, or x86, which would dominate the personal computer market for the next 40 years.

    One reason IBM trusted Intel is that they had proven to be innovators. They had effectively invented the integrated circuit, then the microprocessor, then coined Moore’s Law, and by 1980 had built a 15,000 person company capable of shipping product in large quantities. They were intentional about culture, looking for openness, distributed decision making, and trading off bureaucracy for figuring out cool stuff.

    That IBM decision to use that Intel chip is one of the most impactful in the entire history of personal computers. Based on Microsoft DOS and then Windows being able to run on the architecture, nearly every laptop and desktop would run on that original 8088/86 architecture. Based on the standards, Intel and Microsoft would both market that their products ran not only on those IBM PCs but also on any PC using the same architecture and so IBM’s hold on the computing world would slowly wither.

    On the back of all these chips, revenue shot past $1 billion for the first time in 1983. IBM bought 12 percent of the company in 1982 and thus gave them the Big Blue seal of approval, something important event today. And the hits kept on coming with the 286 to 486 chips coming along during the 1980s.

    Intel brought the 80286 to market and it was used in the IBM PC AT in 1984. This new chip brought new ways to manage addresses, the first that could do memory management, and the first Intel chip where we saw protected mode so we could get virtual memory and multi-tasking.  All of this was made possible with over a hundred thousand transistors. At the time the original Mac used a Motorola 68000 but the sales were sluggish while they flourished at IBM and slowly we saw the rise of the companies cloning the IBM architecture, like Compaq. Still using those Intel chips. 

    Jerry Sanders had actually left Fairchild a little before Noyce and Moore to found AMD and ended up cloning the instructions in the 80286, after entering into a technology exchange agreement with Intel. This led to AMD making the chips at volume and selling them on the open market. AMD would go on to fast-follow Intel for decades.

    The 80386 would go on to simply be known as the Intel 386, with over 275,000 transistors. It was launched in 1985, but we didn’t see a lot of companies use them until the early 1990s. The 486 came in 1989. Now we were up to a million transistors as well as a math coprocessor. We were 50 times faster than the 4004 that had come out less than 20 years earlier. 

    I don’t want to take anything away from the phenomenal run of research and development at Intel during this time but the chips and cores and amazing developments were on autopilot. The 80s also saw them invest half a billion in reinvigorating their manufacturing plants. With quality manufacturing allowing for a new era of printing chips, the 90s were just as good to Intel. I like to think of this as the Pentium decade with the first Pentium in 1993. 32-bit here we come. Revenues jumped 50 percent that year closing in on $9 billion.

    Intel had been running an advertising campaign around Intel Inside. This represented a shift from the IBM PC to the Intel. The Pentium Pro came in 1995 and we’d crossed 5 million transistors in each chip. And the brand equity was rising fast. More importantly, so was revenue. 1996 saw revenues pass $20 billion. The personal computer was showing up in homes and on desks across the world and most had Intel Inside - in fact we’d gone from Intel inside to Pentium Inside.

    1997 brought us the Pentium II with over 7 million transistors, the Xeon came in 1998 for servers, and 1999 Pentium III. By 2000 they introduced the first gigahertz processor at Intel and they announced the next generation after Pentium: Itanium, finally moving the world to the 64 bit processor. 

    As processor speeds slowed they were able to bring multi-core processors and massive parallelism out of the hallowed halls of research and to the desktop computer in 2005.

    2006 saw Intel go from just Windows to the Mac. And we got 45 nanometer logic technology in 2006 using hafnium-based high-k for transistor gates represented a shift from the silicon-gated transistors of the 60s and allowed them to move to hundreds of millions of transistors packed into a single chip. i3, i5, i7, an on. The chips now have over a couple hundred million transistors per core with 8 cores on a chip potentially putting us over 1.7 or 1.8 transistors per chip.

    Microsoft, IBM, Apple, and so many others went through huge growth and sales jumps then retreated dealing with how to run a company of the size they suddenly became. This led each to invest heavily into ending a lost decade effectively with R&D - like when IBM built the S/360 or Apple developed the iMac and then iPod.

    Intel’s strategy had been research and development. Build amazing products and they sold. Bigger, faster, better. The focus had been on power. But mobile devices were starting to take the market by storm. And the ARM chip was more popular on those because with a reduced set of instructions they could use less power and be a bit more versatile. 

    Intel coined Moore’s Law. They know that if they don’t find ways to pack more and more transistors into smaller and smaller spaces then someone else will. And while they haven’t been huge in the RISC-based System on a Chip space, they do continue to release new products and look for the right product-market fit. Just like they did when they went from more DRAM and SRAM to producing the types of chips that made them into a powerhouse. And on the back of a steadily rising revenue stream that’s now over $77 billion they seem poised to be able to whether any storm. Not only on the back of R&D but also some of the best manufacturing in the industry. 

    Chips today are so powerful and small and contain the whole computer from the era of those Pentiums. Just as that 4004 chip contained a whole ENIAC. This gives us a nearly limitless canvas to design software. Machine learning on a SoC expands the reach of what that software can process. Technology is moving so fast in part because of the amazing work done at places like Intel, AMD, and ARM. Maybe that positronic brain that Asimov promised us isn’t as far off as it seems. But then, I thought that in the 90s as well so I guess we’ll see.
