Episode 77. Sql or NoSql, To Normalize or to Not Normalize... that (STILL) is the question

Episode 77. Sql or NoSql, To Normalize or to Not Normalize... that (STILL) is the question 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.

Episode 76. Tick...tock...Time to upgrade to Java 11!

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!

Episode 75. Let's get coding with Kotlin!

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!

Episode 74. Unit and...Integration Tests, JaCoCo, Docker and Coverage (and more!)

In this episode we interview Janine Patterson on her talk of "Integration Test Coverage with JaCoCo" and dive into the nuances of Units vs Integration tests. We dive into Gherkin sentences as we use Cucumber, and challenges of integration tests (hint... use Docker). We also dive into the best way to execute these (Spring Runner). In all, if you were interested in upping your integration testing game, this is the one episode to listen to!

It's new, it's shiny, and is powerful! The new Spring Boot 2.0 framework is out! And we interviewed Spring's own @gregturn to tell us what's new, what's improved and what has changed in 2.0. Diving into a bunch of topics including Reactive APIs, Bob, Greg and I set to explore Spring Boot 2.0 (and why you should upgrade). @gregturn is also the author of Learning Spring Boot 2.0, and he is an authority on many thing Spring.

Episode 72. A very deep dive on Var, and unmodifiable collections with Stuart Marks (@stuartmarks) himself!

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!)

Episode 71. Jigsaw part II, and Java 10 Highlights!

So we finally wrapped Jigsaw in this episode (the most prominent feature for Java 9 (and included a small errata from @stuartmarks). But Java is moving at a breakneck speed, and Java 10 was just released a couple of days ago! We couldn't resist covering some of the new and interesting features of the language. So come take a listen to finish up with Jigsaw, and learn what's new for Java 10.

Episode 70. Let's put puzzles together. Using Java 9's Jigsaw!
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!

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 .

Episode 66. Ok, how about consuming Rest services

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.

Episode 65. Oh my gosh, we missed CACHING! (what a cache miss!)

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!

Episode 63. JCR (Java Content Repository) It as a Document Database before Document Databases were cool!

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!)

Episode 62. Hm, what's the best to travel this holiday? on Apache CAMEL, of course!

So let's talk about one of (if not the) largest, and most interesting framework hosted at Apache. Camel is essentially an implementation of the Enterprise Integration Patterns (EIP) book (which is a mandatory read for the serious dev!). It has so many contributions (and connections) that there is almost no popular system that it can't connect to. In this episode we dive into the reasoning and "spirit" of Camel, to make sense on how to use it. If you ever used Camel, or have run into camel and scratched your head, then definitively take a listen!

It's not the "cool kid" anymore, but it sure is everywhere! If you ever generated an xml file from a java class (or have created a java class from a definition) you have been using Jaxb! And if you have used for some time, you can see that Jaxb sometimes works, and other times...well. Come take a listen and understand what's happening under the covers!

Come hear how you can too master the art of Docker, and more importantly why is it so "accepted" and revered.

Episode 59. A Ghostbuster Reboot? Time to talk about those streams again!

Yeah, today Streams might seem like old news, but you know what? It's worth revisiting and discovering what we didn't know from before. In this episode, Bob, Michael, and I come back to revisit Streams and share what was good, bad (and evil) of them. Including some great trivia on default implementations (a weird Java 8 feature). If you have started to use streams, but not sure if they make sense, or if you are about to dive into them, take a listen! The perspective is great!
