Episode 60. All your Containers Are Belong to Us (An intro to Docker)

So you have heard about it, and probably ran into it already. Docker is a super cool tech that let us create / manage and deploy applications (It is really what would come out if Devs and Ops decided to have a kid). Come hear how you can too master the art of Docker, and more importantly why is it so “accepted” and revered.

A Big Thanks to LaunchDarkly for sponsoring our podcast! Feature flagging is easy, feature flag management is hard. What LaunchDarkly has done is essentially take a system like Google or Facebook has made in-house and bring this to the masses. With features like percentage rollouts, audit logging, and flag statuses, teams have complete control over features at scale. When you effectively separate business logic from code, you can build better software, faster without the risk

Episode 48. Let’s get Groovy with GRADLE in JAVA!

Strike 1, Strike 2, and STRIKE 3! We cover the last of the build tools, GRADLE. It’s hip, it’s cool, it wears a cool leather jacket and rides around on a great motorcycle. The last of the build tools, it has learned from prior mistakes and has combined the best of Ant and Maven into one groovy package. Learn about the last of the build tools, and when to really use it!

Episode 47. Stop. Maven Time!

So moving to a more recent build tool we cover probably one of the more popular one. Maven is now incredibly robust, and helps fixing what is known as Jar Hell. Have you ever used two libraries that depended on different versions of a logging framework? Well, Maven makes using tons of libraries incredibly easy. Come and take a listen!

Episode 46. I’ve got ANTs in my build!

It’s old, but as build tools go you will find apache Ant everywhere. Here we talk on how ant works and explore the build file. While it looks weird, there is nothing to fear! By the end of the episode you will be on your way to tackle any ANT build that have ever been thrown at you!

Episode 39. Do I really have to database it?

It happens all the time, you are working and suddenly you need to database an object. And maybe you have a fancy O/R Mapper or something like that, but we seldom ask ‘do we really need this in a relational format?’. There are actual alternatives (from byte serialization to xml, to, oh, my, NoSql databases). Here we explore the reasons why you may want to skip the Object Relational mapping and concentrate more on ease of development!

Episode 34. New Year’s (2013) Resolution! Less bugs and more coverage!

Episode 34. New Year’s (2013) Resolution! Less bugs and more coverage!

Ok, so we all celebrated (but may not remember) the end of the old year and the beginning of a new year! This is a time for starting new things, and trying to be a little better. How about starting by looking at our code and squish some bugs! By using findbugs we can easily test for the ‘duh’ (and some not so duh) bugs quickly by looking and automatically analyzing our code. After adding Findbugs, we can then add Emma, which will look and measure our unit test code coverage (if you are into such a thing). These two tools are like the Richard Simmons that let us lose the unwanted bug weight in this new year!

Episode 22. Garbage man! An introduction on the finer details Garbage Collection

Garbage collections are like the engine of a car, we know it works, we know that it powers the car, but not much else, but once it breaks down, we usually don’t have a too much of a clue on how to fix it. In this episode we talk about how garbage collections happen, the things it looks for, and more importantly, how it changes your code (there are certain things that you can do to make your code garbage collector friendly). Having this knowledge will help you in the long road on troubleshooting any garbage collection issues (including tuning!), so take a listen to the garbage man!

Episode 21. The JVM Crashed…Now what?!

So you’re programming along when suddenly support calls and says that the application just “disappeared”, or, the server process is not there anymore, both of them leaving you with a hprof.pid file. You have just witnessed the murder of a Java Virtual Machine, and now is your turn to figure out what happen, and what can we do to prevent such senseless crashes. We cover the main reasons for crashes (most likely not your fault), and best of all, ways around it! So put on your detective hat and let’s solve the mysteries surrounding JVM Crashes once and for all!
