: I know of two suspicious and probably
malicious pieces of Windows software that have been seen in the wild,
which falsely cite my name in their version information:
- one first seen in May 2011, which apparently does not use the
same name twice. For example, I've heard of it under the names
or just ‘
q2’, but it could be called lots
of other things too.
- one calling
GoldG’, seen in October 2010.
If you encounter any program claiming to be written by me, and you
can't find it on this web site (and I didn't personally give it to you
by some other means), then it might well be a trojan or virus of some
kind. Don't trust it!

documents on a Windows machine (for example, sending commands back

A collection of miscellaneous Unix utilities.

Articles, essays and things I've written.
How to Report Bugs Effectively: a general
article on how to send a programmer a bug report which will actually
help them fix the problem.
Coroutines in C: an implementation of
Knuth's "coroutines" concept in portable ANSI C, by a similar
technique to Duff's device plus some C preprocessor abuse.
Metaprogramming custom control structures in C:
another piece of C preprocessor abuse to let you build quite general
user-defined looping constructs alongside C's basic
Magic Aliases: a dirty trick you can do
by combining aliases and shell functions in the Bourne shell.
The Infinity Machine: an exercise in
what you might call "recreational computer science", inspired by Ian
Stewart. Explores the potential consequences if an infinitely fast
computer could be built (including defining precisely what that
