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!

Episode 20. Excuse me, do you know what Date it is, or what Date is? A discussion about Date and Calendar in Java

In this podcast we turn and talk of that embarassing uncle that every API has (java.util.date), you know, the one that you have to live with because is family, but don't really like that much? We dive into what to avoid when using Date (and Calendar), and the most common pitfalls that we have falled for (1000*60*60*24 anyone?). In all, if you have used date extensively you probably already migrated to JodaTime, but if you are a casual user, then take a listen, just to make sure you are not bitten by the Date traps!

Episode 19. But Wait, there's more! SerialVersionUID! XMLEncoder/Decoder! Java Beans!

Episode 19. But Wait, there's more! SerialVersionUID! XMLEncoder/Decoder! Java Beans!

We finish our discussion on the ObjectOutputStream by covering the SerialVersionUID, and then move onto ObjectOutputStream's citadine cousin, XMLEncoder and Decoder (and why would you go and hang out with it). We also make a quick introduction to "The Bean" (Java Beans that is), and discover there isn't too much to it. If you are persisting and/or transmitting, listen to the shocking conclusion (gasp!) of serialization!
