Here's a great introduction on MIDP programming with J2ME. If I only had some time, I would implement my own midlet for a project management and mindmap tool.
Good riddance, Metal and Awt; this may boost Java applications, at least on Linux : the next version of Java (code name 'Mustang') will feature native GTK components for the Swing API.
More mobile fun : the Java applications provided with my mobile phone are mostly stupid Java games. I really want some more productivity applications found on modern PDA's, like a Palm or Ipaq. So I took a look on my phone''s file system, and found out that most Java applications are MIDlets, Java applications suited for embedded devices like mobile phones. Midlet.org is a site where you can find some interesting applications, like grocery lists, scientific calculators, or telnet clients to run on your mobile, and transform it to a real PDA device. Next step is developping my own MIDlet applications, like explained in this developersWorks article.
I was discussing a Perl project with a collegue, when one made the remark that actually there's no real Perl IDE (apart from Emacs or Vim, of course). I said that Eclipse maybe could be a solution, and lo and behold : two minutes later, my collegue found the website of EPIC, which is a very impressive Eclipse plugin. The number of Eclipse plugins is really impressive, even Clearcase plugins can be found. They now can all be found on the Eclipse plugin website.
Some days ago, I pointed out that Eclipse entered Debian. Unfortunately, there are still some problems to be solved for the Debian package. Luckily, the default Eclipse zipfile turned out the be a breeze to install.
