Chaotic Java

Java Logger Memory Leaks

Aviad — Sun, 05 Jul 2009 18:13:52 +0000

Recently we switched from Log4J to the java.util.logger package (for this entry it will be called the “Java Logger”). Why, you might wonder, and I don’t have a good reason to give other than the illusion the Java Logger package gives as being more standard. I would like to stress the word illusion for a [...]

JSR 296 brings a "Swing for the rest of us" approach for Swing application development.

Jsr-292’s first draft – a late review

Being fashionably late as always, I read the JSR-292's early draft and had some comments on it

IO performance – Tar vs. File vs. Byte streams

Aviad — Sat, 06 Dec 2008 23:12:48 +0000

One of the most classic patterns in software is the producer-consumer pattern. There is a module producing data, and a module reading it for further processing. Moreover, in order to achieve better performance, usually there are many consumer modules running on many different threads while the producer (or several producers) run on its own thread. [...]

Project Darkstar, Unit Testing and Mock objects

Aviad — Thu, 28 Aug 2008 20:16:02 +0000

Ever since I started using TDD (test driven development) methods in my work, I never stopped. I rarely start a project without knowing how I’ll test it, and not just in Java: C#, Objective-C, and Python as well. I’ve found that TDD can be done in the most unlikely places, such as servlets using Cactus [...]

Build.xml generator for Eclipse

Aviad — Sat, 19 Jul 2008 21:01:22 +0000

Know the feeling when you’re just about to release code to the public’s eye, and all you need to do is write that pesky build file? Even as I write it I feel it’s an understatement: the task of creating an ant build file can take a few good days out of anyone’s life, and even [...]

Administrative: Problems with the server

Aviad — Sat, 24 May 2008 17:57:28 +0000

I’m having a lot of problems with the server lately. Many people have complained that they have tried to leave comments unsuccessfully, I hear that the RSS feeds sometimes don’t work, and even my own management is sometimes blocked off. I am figuring out the steps I should take – upgrade my current hosting plan or [...]

Switch by class type

Aviad — Sat, 24 May 2008 04:46:52 +0000

Imagining a method which receives as a parameter a type Object instance and needs to perform some action according to its type is not difficult. In fact, there are several design patterns that, when used in combination, help solve just that. However, this post is about adding a new switch..case construct to prevent some boiler-plate [...]

Exposing collections: paranoia vs trust approaches

Aviad — Mon, 19 May 2008 06:17:35 +0000

Whenever a class in my model contains a collection which requires that particular care be taken with its items, there’s an internal debate regarding how to expose it to other classes. And with this, there are two major schools: one, the paranoia-based approach which doesn’t allow external code to touch the collection’s internal items and [...]

Garbage Collection – The comic panel

Aviad — Sun, 11 May 2008 15:46:45 +0000

The Garbage Collection set of posts (Generations, Parallel and Concurrent, Tips and Memory Leaks) are ones that I am personally very proud of. First, they were very interesting to write, as the material is extremely interesting; second, a lot of people seemed to enjoy them, and found interest in reading them; and third, it seems [...]
