Java Pub House

So the internet is all raging about this (not so little) framework that is doing it all. Created with a "cloud-first" mentality, @Micronautfw is aiming to be your next Spring Boot! And, oh gosh, how easy they are making it.

We dive into what makes Micronaut such a darling of the internet right now (not using reflection, GraalVM ready, better memory consumption) and see how much "stuff" is in there (the TLDR; A Lot). We go from creating a microservice, to looking at the different already-implemented features like circuit breakers, properties/profiles, beans, support for lambdas, micrometer, reactive programming, and all. While it might not have "everything" that Spring does, the reality is that it's pretty solid.

Would you consider Micronaut for your next project? The answer is maybe (and for some cases, maybe Yes). So come, and take a listen to the underdog framework (Micronaut) that's stepping up to definitively take the reigning Champ (Spring)

Ah, Project Lombok is one of those little gems in the Java Ecosystem. But it's interestingly controversial! Some will love it (as I do), others will hate it! But no matter which camp you land on, you should at least know about it!

Project Lombok allows you to, quite easily create your equals/hashcode method, or create a builder pattern for your class, or even generate your getters/setters. All while just adding a simple annotation to your class. How does it do it? (hint. It's preprocessing bytecode magic) But holy cow, when used responsibly, Lombok allows you to write so little code for a ton of cases. So come take a look at why this library is powerful (and learn its benefits, and as importantly, its pitfalls)

Nothing like a cold chilly day to stay inside and program some more. Before you start that new project from scratch, let's go over a pretty cool feature of Maven. Maven Archetypes! Learn how to create "project templates" for your new maven project... or better yet, use one of the predefined maven archetypes already out there.

We go over how easy is to create your own, and over the flexibility on the things you can do! Are you trying to get all your development teams to start with the same libraries, support, or template? Are you using maven? Then the answer is easy. Create an archetype for them! Come and take a listen as we use Maven to create Maven Template for new Maven projects.

So for our new episode we decided to give YOU a holiday gift! Apache Commons! We covered one of the libraries that is ubiquotous in anyone who programs Java, but that not many know how robust and complete it is!

Do you have to do things like averages, min, max? Or do you have to read CSV files? What about measuring pieces of code with currentTimeMillis? or creating deep copy of Bean objects? Well, these and much more are already supported in the slew of Apache Commons project (and subprojects!). They usually have no transitive dependencies either so they are "ready" for the taking. And because Apache Commons is already used in many open source libraries, chances are that is already in your own project! Making it an easy thing to just start using it.

Happy holidays, enjoy this little gift from all of us :).

OracleCodeOne just happened... and Freddy and Bob couldn't go... So they recruited the help of Josh Juneau to go out there and capture interviews from anyone who would talk to us! Apparently they did, and we packaged all in this hour-long episode for your enjoyment! Everything from community building, to what's hot in the Java space, to takes from the conference are covered in this series of five minute interviews.

So take a listen! It's the next best thing if we couldn't go to OracleCodeOne.

So you may have thought about using NoSQL or a Document Database for taking care of you needs. But do you know why that might be not be a good (or a pretty bad idea?). Or you may have a Database that have been running fine, but it seems that you can't work with it anymore? (Is it time to move to NoSql? Would it help?).

We dive into the "Why" would you choose Databases vs NoSQL Data Stores, or when to ditch your MongoDB and actually come back to MySQL. In our current time of "WebScale" and "CloudReady" we get bombarded by choices! (Mongo, Dynamo, MariaDB, ElasticSearch) and while some of the offerings are great, it might not mean that is the Right choice for what we need to store.

So take a listen as we explore normalization and the strength and weaknesses of relational data vs unstructured data.

It's coming! If you have been using Oracle Java 8, you should know that starting on January 2019 we will have to get an oracle license for running Oracle's JDK in production. OR, if you want to keep using Oracle Java (or OpenJDK) for free, and still receive security updates, then you gotta move to 11!

In this episode we have no other than @DrDeprecator itself giving us a tour on what are the less-known changes (and goodies) that are coming when upgrading from 8 to 11. We go through most of the JEPs that usually don't make the news but are actually pretty awesome!

So take a listen, and start downloading the new Java 11!

While Freddy is travelling from Chicago through the West Coast in a minivan, Bob talked to Todd Ginsberg about the new darling language from the JVM. Kotlin is much more than a novelty now, and with Android support, and some time to "work out the kinks" it has been used Mainstream. Have you been curious on what makes Kotlin interesting, and "fun?". Have you been thinking of taking it for a spin? Well, wait no more! Listen to this episode as Todd takes us through the coolest part of Kotlin!

We went to one of the best sources to learn what's happening with Var and Java 10, @stuartmarks! Also, what has been (and is being deprecated) on Java 10, and 11. And little inside perspective of having a new java version every six months!

Included is a the "convConvenience Factory Methods for Collections" List.of, Set.of, Map.of that @stuartmarks did for Java 9! (and his new contributions for Java 10). And a interesting trick of the non-deterministic order of unmodifiable sets! (A Stuart Marks special!)

So come and listen to this episode which contains great tips and tricks directly from one of the contributors to the Java Programming Language API!

It was both the most anticipated and (one of the) most controversial features in Java 9. What's the bruhaha all about? What is Jigsaw (or the Java Platform Module System)? What does it bring? Can I use it? And if so, why would I use it? All these questions are answered as we dive into the history of JSR-376 (it has been years in the making). And since Jigsaw is so big, there might be a two-parter for us! So stay tuned!

Episode 68. Clouding it up with Microsoft Service Fabric

Clouds are everywhere and are puffy! In this Sponsored Episode, we dive into one of the main prominent cloud providers out there (Microsoft), who is outreaching to us Java Developers! (gasp!). In this episode, the Microsoft Service Fabric team (with @mani_ramaswamy, @HuruliS and Raunak Pandya) takes us in a soup-to-nuts tour on how to get started with Azure's service cloud, including what makes it different from others. Bob and I dive and explore how well would this work for us Java folk (and the answer is "very well") taking questions from how to build and deploy cloud, to what native support is there is for us Java Folk .

So we talked about how to create a rest service (using things like Apache CXF and Spring MVC), but sometimes, we actually need to consume these rest services. Luckily within the Java ecosystem there is a lot of way to skin that cat, and in today's episode we at least cover 4 ways of doing so (including my favorite of the day, Feign). Come take a listen as we dive into Appache HttpComponents, Apache CXF with JaxRS, Spring RestTemplate and Netflix Feign on this fully-loaded episode.

What a strange omission, of all the concepts, one that all of us should always have is Caching. We have used it (and most likely we have been burned by it). Come and take a listen on how to correctly (or at least not as incorrectly) think about caching, finding out your "game plan", and using JSR-107, or Hazelcast, or Apache Ignite or Spring. LRU? Time-based? How much memory? Long distribution tails? cacheable keys? All concepts that you should ask before creating/using a cache!

The Java Content Repository (JSR-170 and JSR-283) have been around for a while. For those who don't know it's an actual way of managing content (or assets, or text, or images, or a catalog). Its use can be almost anything, and yet, we didn't know we had it! The best part? It's a JSR so not just that there are different, compatible implementations, but the underlying storage can be changed in a jiffy. Want to store as files in the filesystem, done. How about a Database? also done. How about using something that the cool kids use like Mongo? It Got you covered man! (or Woman!)
