SatireWire Calls it a Night

It is with sadness that I read that SatireWire is on a permanent leave. I have been a fan for the last few years, but now it is the end of the road. Links to some of the better pieces: - Axis of not so evil - Religious mergers -... [Read article]

Mathematics Incomplete?

Mainstream mathematicians tend to like to believe that everything in this world can be explained, and proved, by use of logic or mathematics if you want. I guess I did too, atleast up until a professor gave me the name of Kurt Gödel... Kurt Gödel (1906-1978) was the name of... [Read article]

Statistical Analysis of Spam - Part I

Spam Filtering - To Do or Not To Do

Spam has become an increasing problem. There are many ways of fighting spam. Relay blacklists and filtering out e-mail without the correct To: header was the first generation of spam filtering.

Is MovableType A Time-Consuming Curse?

When suddenly an entire afternoon evening is wasted tweaking different blogs, both my personal blog and a system of blogs for CISV [1][2] without even planning it one might actually think so.

Internet Telephony - part I

Internet Telephony, either as IP-to-IP (NetMeeting) or IP-to-Phone (Net2Phone), emerged sometime in the mid 90's. I was not very attracted in the beginning. Voice quality was poor and my Internet connection was merely a 28.8kbps modem line. Since then I have moved to a flat with a 10Mbps connection directly... [Read article]

Anders, on his everlasting search through the internet has found another neat little application. The 100KB[*] app Aggie searches for news from all defined newsfeeds.
