Partial Update

Ok, I must just post something. Otherwise it will just become even more embarrassing when the message “upgrade postponed” sits on top for a whole month and I’ve upgraded not once, but twice, in that time frame. Not that I have much to tell, I’ve some things that I plan to post but couldn’t find […]

WordPress Upgrade Postponed Until Weekend

I’m going to upgrade WordPress to the latest 2.1 version this weekend. Not that it should matter to you or the day to day business of this blog. I just want to mention it because I will not get around updating my own plugins and widgets, of which one is reported broken, until after the […]

Matt Mullenweg’s business card allegedly instructs people just to enter “Matt” and hit “I’m Feeling Lucky” to get to his site. Well, now I can instruct people to enter “Ironicist” and hit “I’m Feeling Lucky”… should I dare to say that it feels “ironic”?

Verhoeff’s Dihedral Group D5 Check

I just finished implementing the Verhoeff checksum algorithm in PHP, you can download it as Yes, mathematically it’s a bit more elaborate than other checksum algorithms, but with look-up tables it’s fairly simple and lightweight.

Blog by Numbers: Don’t Shoot the Mime, TeX!

I’m currently working on an article that make use of some math notation. Normally, in such cases, when you need something out of the ordinary that can’t easily be marked up as XHTML you render an image (yes, I know about MathML). It’s quite easy to render beautiful math formulae off-line. But making the round-trip […]
