Just as is the case with most personal websites, this won't be of
any use to you. But if you have really nothing better to do...
Onsite material:
- Blogaria: A collection of
snippets that I can't find any other spot for.
- Bored section: random
pictures taken by mobile phone whilst having nothing better to do.
- BSgen
is a bs generator for corporate e-mail memo's.
- 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,
and a few tips on how to use all this.
- Dial Whatever: incase
you wonder whether there's a nifty nerdy word hidden in your phone
number.
- Dnspb: a DNS proxy/balancer.
This is a serspace program that forwards incoming UDP or TCP DNS
requests to a number of back ends.
- e-xmlpp: a fast XML
prettyprinter.
- FCH was my first useful C
program ever.
- 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
implementation w/docs.
- Jpeginfo: a tiny tool in C
to show information about jpeg images.
- Kalk is a C-like calculator
that I still use.
- Lectures are
presentations of some of my lectures. Downloadable in PDF format.
- Microproxy is my tiny
C++ proxy for http and https.
- MSC is my collection of Missing
Shell Commands. Basically bash commands that I feel
extremely unconfortable without.
- Nasa Pics is a collection
of cherished astronomy images.
- Off The Grid, my page on Steve
Gibson's hand-usable encryption.
- PGP Key lists my public PGP
key and fingerprint, incase you want to mail me and wish to use a
'sealed envelope'.
- Posters, silly stuff.
- SafeEdit is
yet-another-tiny-Perl-script that I use for -- yes, safe
editing.
- Simple Listserv is
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.
- Wallpapers are some of my
desktop photos that brighten up my lappie.
Local Weather

It's always the same in this datacenter.
Offsite material:
- e-tunity is a Dutch ICT company, of which I'm
co-founder (www.e-tunity.com).
- Crossroads is my pet project, a level5 TCP balancer
/ failover utility. It also does fancy tricks for the HTTP
protocol (level7). Check out --
- Easy SVN Viewer, one of the packages at public.e-tunity.com, also has
its separate project page on freshmeat. It
allows one to set up a web-based Subversion repository browser
really quick, via just one cgi-based Perl script that handles all.
