combinatorial game software
As I am going to give a talk on Combinatorial Game Theory early next month I have to update my rusty knowledge of canonical forms of two-person game positions, their temperature theory and the like. As most of the concepts in this field are recursive they are hard to work out by humans but easy […]

SSL on Mac OSX
A longer term project is to get the web-server www.matrix.ua.ac.be integrated in our home-network as an external WebDAV-server (similar to the .Mac-service offered by Apple). But as this server runs all information about the master-class on non-comutative geometry connecting to it via HTTP to use WebDAV is too great of a security risk as all…

MacStumbler and iStumbler are active scanners sending out probe messages to the basestations and can therefore be detected easily. Moreover, they are not able to detect closed networks. So let us move up one step in the secrecy scale and get some passive network scanners running. The first one is KisMAC which instructs the Airport…

Not all improvements to our home-network need to be high tech. Here is a very simple measure which reduces the amount of in-house shouting drastically. Often all of us are online, either to work, surf the net, MSN-chat or listening to iTunes and clearly we can easily see which other computers are on at the…

graphite ABS can be used
I found on the net a way around the problem that a first generation graphite airport basestation is not compatible with a third generation extreme ABS. The article is called Extending AirPort’s range with multiple base stations and addresses precisely my problem (a problem that others still think is not there judging from the replies…
