Further releasing bits of code I have lying around: here's Compressor.java, a lightweight (J2ME-friendly) range encoding compression algorithm in 4k of bytecode. Released under the LGPL.

Cybersyn
A Gernsback Continuum moment:

Cybersyn was, oh God, a cybernetic command and control center for the Chilean managed economy of the 70s. I'm not sure what's left of the thing itself but there is a nice website memorialising it.

Lightweight Encryption for Java/J2ME
I've got a few useful nuggets of code lying around that I've been meaning to open-source for quite a while. One of them is a Java/J2ME implementation of David Wheeler and Roger Needham's Tiny Encryption Algorithm. Today I tidied it up and stuck it online. It's handy if you want a robust cipher in less than 2k of bytecode. You can snag it here.

Reluctant blogging
Hello world. My name's Joe Halliwell. I am a reluctant blogger.
I tried it once in 1996. I spent a week or so writing a blog "engine" and designing the layout. Then, three posts in quick succession. Then, nothing.
Omen absit.
I met a guy the other day who runs three blogs. Once a month he sits down and writes 30 days worth of posts for each of them. Often he'll write an essay then divide it into chunks. He is a machine. I admire that in a person.
Still, I won't be trying to emulate that prodigious output. I would do anything for PageRank but I won't do that. Like you care. Let's just see how this goes, shall we?
