Episode 35. Recursion, Doubles and Strings (A little for everyone!)

You remember recursion right? that ugly, confusing thing they made you do either on CS-300, or at job interviews. Have you ever wondered how to make it safe and right? and why do we really use recursion? In this episode we go into proper recursion programming (and lose the fear of making it wrong), and understand why stacks get filled with it, and what problems do they really solve (answer, not many).
In addition we talk about the nature of Double objects, vs double the primitive (And why it is so hard to do == comparisons in doubles), plus some little known things about Strings (like interning). In all it has a little bit for everyone, so take a listen!

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 33. Does code dream when it hibernates? A quick look on the big things of Hibernate

Databases have been around forever! (or at least from the 1970s) and there are many things that try to hook Object Objected Programming with Relational Databases (namely, O/R mappers). Hibernate is the most known O/R mapper and, while effective sometimes it can be confusing. In this podcast we delve on how to understand our misunderstood friend, and finally fix those pesky weird Hibernate exceptions once and for all!

With the establishment of Java 7 as the de-facto JRE of Oracle, the clock is ticking down for Java 6! It will be End-Of-Life around February 2013, so we better get going and upgrade! In this episode we cover how to migrate to Java 7, and cover some of the most notable Java 7 features (Networking nuts, your prayers have been answered!) while preparing a path to upgrade. If you have a Java 6 (or 5 or 4) project, this is mandatory listening!

Episode 31. Know your bounds! Generic bounds that is (a story that extends super!)

Big shout-out to everyone I met at JavaOne (including some avid podcast listeners!). Thanks for listening and for a great time down at JavaOne! Don’t worry, we will be sharing all the stuff I learned on new episodes of the podcast.

It is also our Birthday (We have been airing episodes for a year!)! Happy to celebrate with everyone a year of the podcast (and if you want to celebrate it, treat me a beer! 🙂 ).

With this episode we wrap the concept of generics and bounds (super / extends) and talk about type erasure (and compiler warnings that goes ‘Hm, dunno what you’re doing but I can’t make sure it’s right’

And, that…is that!

Episode 30. I always thought Generics were as good as brand name Erasers (Java Generics part 1)

Hi there! Finally back on a (hopefully) standard schedule. I have been moving a house with three kids, two cats, one wife, one dog, and one grandma (they are heavy!, just kidding!) and just found the box with the podcast equipment!

we hit the ground running with Generics. What are the benefits (and potential pitfalls) of Generics? Why do we even need them at all? The syntax looks pretty confusing, but with some Jedi Mind tricks one can actually start seeing how they work. If you use Generics (Almost everyone does :)) you should take a listen!

Episode 29. Scope (or how far away can you call), Inheritance, marker interfaces, and overrides!

Episode 29. Scope (or how far away can you call), Inheritance, marker interfaces, and overrides! —-
We go and visit the Primordial Java Concepts. As rules set in stone we explore the concept of multiple inheritance, method and variable scope (including the final keyword), abstract methods and @override. This is good for those starting up their Mad Java SkillZ (We’re L33T, u K||0w?), or for those who were always curious why the language is this way.

Episode 28. Extra! Extra! JMS Delivering Messages to your App! Extra! Extra!

Episode 28. Extra! Extra! JMS Delivering Messages to your App! Extra! Extra! —-
Java Message Service (or JMS for short) is a collection of APIs and implementations that allows you to send “messages” across your applcation. But why is it so popular?, and what exactly is it trying to solve (what is a message anyways)? In this episode, we take our bycicle, and trace the delivery route of JMS to figure out the good, and avoid some JMS potholes along the way, making for a smooth message delivery experience!

Episode 27. There’s a Log File in the folder in the middle of the App

(Sing to the children’s song There’s a hole in the middle of the sea)
Logging is part of everyday production debugging life. If you ever had to troubleshoot a production application, the you most likely have looked at log files. These log files can either be a salvation, or an inmense source of frustration. In this podcast we delve into the different logging frameworks, and more importantly, what to log and not to log (and how to log it).
