The imminent death of J2ME ?
Sunday, September 27th, 2009 | Author:

The iPhone, Android, Blackberry, Symbian and Windows Mobile platforms seem to be all the rage these days. Everyone’s talking about them, everybody’s using them and everybody’s praising their state-of-the art capabilities.

In fact, some even believe that they will bring with them the death of J2ME, citing the platform’s age, speed and primitive API as its mortal weaknesses. While there is some truth to these claims (J2ME is pretty old, and more modern platforms do have some pretty cool applications running on them), make no mistake about it: J2ME is not going anywhere anytime soon.

Find out why after the jump.

Incredible J2ME Voxel Engine

This is by far the coolest piece of J2ME software I’ve seen lately:

This video was embedded using the YouTuber plugin by Roy Tanck. Adobe Flash Player is required to view the video.

According to the video description, this uses no 3D API whatsoever. It’s just simple J2ME code. I’m absolutely stunned.

Pre-calculating values
Saturday, July 25th, 2009 | Author:

Pre-calculation is a very useful and neat programming trick that will allow you to “squeeze” more processing power out of your hardware.

In its simplest form, it involves only three easy steps :

  • Step 1: do often-used and/or complex computations only once per run (for example, during application start-up)
  • Step 2: keep the results of the computations in memory
  • Step 3: from that point on, wherever needed, use these results instead of re-doing the computations

In this tutorial I will show you how to effectively use pre-calculation to considerably speed up your code.
