Update 2024-03-09: none of this would work anymore, one uses application-specific passwords to avoid storing the main account password in plain text in .mpoprc!

Here’s a short note on Gibbs sampling, explaining a simple case with two random variables: gibbs.pdf.

To fix the strangely large Firefox fonts in Ubuntu Karmic: sudo rm /etc/fonts/conf.d/10-hinting-slight.conf sudo rm /etc/fonts/conf.d/10-no-sub-pixel.conf sudo ln -s /etc/fonts/conf.available/10-hinting-medium.conf /etc/fonts/conf.d/. sudo ln -s /etc/font…

At EuroPython 2009 I met a guy from Bet Fair who told me about the UCT algorithm.

Just putting up a PDF of an interesting article: Kurt M.

To quote Barnett (2006), the Slutsky effect, as understood by most economists, is the following: If the variables that were taken to represent business cycles were moving averages of past determining quantities that were not serially correlated – either r…

Here are step by step instructions for compiling gcc 4.2.4 on a fresh installation of Solaris 10 x86.

The left audio channel on my work computer crackled badly.

Here are notes on compiling gambit revision 6294 (the current latest) from the SourceForge gambit repository.

Some of my research is on dissections of triangles into equilateral triangles.

In The Physiology of Willpower: Linking Blood Glucose to Self-Control (Gailliot and Baumeister) (local copy: PDF) the authors look at the effect that exerting one’s willpower has on blood glucose levels.

After reading Why we make mistakes I wanted to read more about the calibration of bridge players.

An interesting paper by Paul J.

This is just a short note on how to use the Eric4 program to debug a Sage script (a .py file).

A while ago I got a paper published in a Springer journal.

I wanted a listing of the blocks of the 2 nonisomorphic STS (Steiner Triple System) on 13 points and the 80 nonisomorphic STS on 15 points.

Update (2009-04-23): after a reboot my WL-500gP no longer booted Debian.

In a recent post I compared my Cython and C++ implementations of a depth first search algorithm.

Why do our across-the-street neighbours have newspaper hanging from the top of their window?

Edit (2008-11-09): Robert Bradshaw posted a patch to my code and the Cython implementation is now a lot faster.

For a while now I’ve been using my own C++ implementation of Knuth’s Dancing Links algorithm.

I recently discovered that OpenSSH has a built in SOCKS proxy.

PyX is a Python package for the creation of PostScript and PDF files.

The graph below compares a brute-force depth first search in Sage/Python (red line) to an implementation of the same algorithm in Cython (blue line).

One thing that I really like about Sage is that it uses Python as its underlying language.

2008-10-19: I use PyX instead of Metapost.
