Java Pub House

Designers will come to you, and say "Hm, I think your program is not as user-friendly". And sometimes, when you ask them to elaborate, they seem to follow a hidden and cryptic ritual. They are right, yet, is hard to see how did they come up with those usability suggestion. Alas, behind every usability magician, there is a magic trick! and on this podcast we reveal in plain sight what makes interfaces usable (and quote a lot from Alan Cooper's book). Once you see the trick, you would never be daunted on spotting usability yourself, and making things much more usable before passing them on. Usability magic for all of us!

It always starts when you do your first Thread.sleep(). Why do I have to check for InterruptedException? is it serious? why do I have to catch it? We start with answering these questions and step down the rabbit hole to discover the inner workings of Wait/Notify (and what the IllegalMonitorStateException really means). If you ever have to work with more than one thread (who doesn't nowadays?) take a listen! You'll be notify()ed of your success!

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!

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!

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!

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!

We all have the need to serialize/deserialize objects (either through the "wire" or to file). In this podcast we go and analyze what exactly happens when we create an ObjectOutputStream and write to it, and more importantly what pitfalls are there to avoid (Out ot memory errors, stale object updates, Not Serializable Exceptions, and toenail fungus!). If you ever considered using ObjectOutput/InputStream, or are actively using in your current projects, take a listen!

Every developer at one point in time runs into the question, what is beautiful code? Is it code that is expressed concisely? is it code that does a lot in a few lines of code. Well, while we're not the DeveloperPeople's magazine at least there are fundamental concepts that describe code beauty. And while there isn't a consensus (what is beauty anyways), at least there is a baseline for code that is not ugly (hint. It's maintainable). At least a conversation starter, this podcast covers the very minimum that code has to be to not be ugly!

The State pattern is very useful, it's just hard to spot, and at the beginning a little hard to understand. On this podcast we cover the state pattern with a specific example of its use, plus tips on how to spot when to use it (really that's the hardest part of the state pattern). Check this podcast out, and add another pattern to your toolkit!

Taking the performance theme, we move into the dark corners of Java Swing and discover that it is not a lame horse at all! Swing is very fast (with support for directX and OpenGL!), but sometimes is hard to get it to perform right. In this podcast we talk about how to make sure of respecting the EDT, offloading from the EDT, we explain how the EventQueue works, and show THE technique for fast GUI performance. If you know what Swing is, tune in! We will dispell Swing's performance myths!
