- C-conf is a very light-weight
automake-like tool to help in the construction of C/C++ programs on
different platforms. It works fine with standard GNU make (doesn't
require e.g. cmake).
- Cookies are random witty
quotes that I've schlepped around with me for quite some
while. You can see my collection of cookies, a Unix cookie program,

fe is a file encryption utility
that has some fancy tricks. It can start processes, with its
crypto layer transparently "transcrypting" during the reads and
writes that the processes do.
fswatch is a filesystem
watcher: it checks for changes under a given directory and runs a
command when a change is seen. Great for continuous builds and
- HammerServer is a
networked process where arbitrary data are stored and can be
retrieved. The server makes sure that data tampering (e.g., by a
malevolent database administrator) is detected. Hence, the
HammerServer provides ``tamper-resistance''. The next step in
security would be probably a tamper-free log - which is very hard to
achieve and involves specialized hardware. It's a Perl

very simplistic replacement for the venerable "listserv" program.
Simplistic, and very easy to set up.
- Syscheck is stil
yet-another-tiny-Perl-script which reads a configuration file and
can check the health of a Unix system. I use it to make servers
self-healing, so I don't have to watch them.
