I wrote Processing HTML a while ago, when b3ta filtering was in it's infancy. To accompany the latest changes to b3ta's filtering engine, i present:

Having trouble finding things? Then the new iamcal search site will help.

There's a new directory of esoteric programming languges.

dafont have stolen my fonts and put them up for download, without asking me >:(

This software makes reasonably good code flowcharts - it can handle javascript too. The output is usually good enough to understand, but not presentation quality.

NASA have a nice toy for viewing things in space. Looks quite like elite to me. [via JenR]

Purple Pussy is, i think, fantastic. Worth reading from the beginning. And reading the old ones too. A good exmaple of what it's all about: here

J Greely at dotclue.org has used my Graphics::ColorDeficiency perl module to great effect: random color schemes that contrast

After having seen t3, here are some photos of clare danes. Mmmmm [via #h8luff]

People are seriously allowed to publish this sort of thing? "The Australian author Jasmuheen has not eaten any food for 5 years. This book describes how this came to her and a special 21-day process to convert the body to the new way of being sustained.". Liar. [via Ody]

I've been going module mad lately and actually releasing some of the more functional of my perl modules onto CPAN: [CSS](http://search.cpan.org/author/IAMCAL/CSS-1.04/) [Graphics::ColorDeficiency](http://search.cpan.org/author/IAMCAL/Graphics-ColorDeficiency-0.01/) [Inline::Interp](http://search.cpan.org/author/IAMCAL/Inline-Interp-0.04/) [Language::Homespring](http://search.cpan.org/author/IAMCAL/Language-Homespring-0.04/) [Language::Homespring::Visualise::GraphViz](http://search.cpan.org/author/IAMCAL/Language-Homespring-Visualise-GraphViz-0.03/)

Ponie (perl5 on parrot) should be pretty cool. You can read about that and more at the perl 6 talks site

Matt Biddulph did an excellent talk on RDF. If you didn't understand RDF before, you will now.

A new comic for your consumption: return to sender

New articles by me:

Designing user authentication systems

The problem with cookie authentication

There are also a whole bunch of new articles added to the publish section which were going to be in Ben Hammersley's "Blog Hacks" book (which, sadly, O'Reilly decided not to publish).

I've been meaning to do this for ages. The Ikea Game is old news. Trendy people play The Paint Game

I've finally gotten round to correcting thinkgeek's geek shirt

If i ever get bored of carrying my laptop everywhere i go, then i'll but one of these babies

You really need to take this geek test. It takes quite a while to fill in, but it's worth it. Ste (neuron sysadmin) got a mere 30. I got 56.6075% which makes me an "Extreme Geek". Post your scores as comments. [via ste]

Ooh, nice posters [via pep]

More ooh : guy is back

Rejoice!

Today is the third birthday of iamcal.com

Three years of discussion, arguing and bad in-jokes.

To celebrate, we're all going to london tonight to get drunk. Anyone and everyone is welcome. If you'd like to go, drop me an email, post a reply or phone/text me (07899 835995).

We'd love to see you :)
