While being a physicist by training (having mostly worked in Electron Spin Resonance (ESR)) I got a bit sidetracked into fiddling with computers. One of the results is my program for controlling spectrometers, fsc2, a number of Linux device drivers and other stuff (see below). At the moment I work for the Dept. of Education and Psychology of the Freie Universität Berlin in a group that tries to figure out how the brain works (or at least to understand a bit more about it;-), using a wide range of techniques like EEG, fMRI, NIRS (Near-InfraRed Spectroscopy, where they shine lasers into your skull and try to deduce what's going on in there from the light coming back) and several others. I'm involved there in writing programs to help visualize and analyze all the data recorded (and serving as a guinea pig from time to time;-).

fsc2 is a program for
controlling spectrometers. Its main features are: easy to adapt
to different hardware; running an experiment is controlled by a
simple interpreted language, so it can be used to do basically
all kinds of experiments, i.e. it's not restricted to a certain
built-in set. |

A project I'm very interested in tries to support teachers at
primary schools and educators in kindergardens in doing science
education via an inquiry-based learning method (i.e. the
children figure out things by doing experiments themselves,
not by having the teacher tell them how things are supposed
to work). I'm one of the collaborators (mostly taking care of
the technical side of things) of the German mirror-website of
the French site
La main à la pâte:
The website is supported by the Académie des sciences, the Berlin-Brandenburgische Akademie der Wissenschaften and the Freie Universität Berlin. |

I'm one of the maintainers of the XForms GUI toolkit for X
which can be downloaded from
The project homepage is at xforms-toolkit.org where you'll also find the HTML version of the documentation. |

I've had the good luck of getting asked to do a bit of
technical reviewing for an amazingly good new book about system
programming under Linux and UNIX by Michael
Kerrisk (who's also the maintainer of the
Linux
man-pages project):
If you're seriously interested in programming under Linux/UNIX I'd strongly recommend that you take a good look at it - I consider it to be the best and most comprehensive book on this rather broad range of topics available and a worthy successor to Stevens' famous Advanced Programming in the UNIX Environment. |

sha_digest is a package that
implements the SHA-1, SHA-224, SHA-256, SHA-384 and SHA-512
hash digest algorithms as defined by the
FIPS
180-3 standard (for both byte- and bit-oriented messages).

Linux device driver and library for
National Instruments GPIB
cards (AT-GPIB/TNT and PCII(A), but also seems
to work with some other cards based on the µPD 7210 chip)
for kernels 2.0, 2.2 and 2.4 and 2.6:
Also includes a Perl package for talking to the GPIB devices. Last update: November 4, 2008 Please note: for most cases I would recommend to use drivers from the Linux GPIB Package, which probably is more mature. |

Linux device driver and library for the
National Instruments
6601 GPCT (General Purpose Counter and Timer)
card for 2.4 and 2.6 kernels, allowing event counting,
pulse generation and DIO:

PCI E-Series DAQ cards for 2.4 and 2.6 kernels

Linux device driver and library for the RULBUS
(Rijksuniversiteit
Leiden BUS), including support for RB8509 (12-bit ADC),
RB8510 (12-bit DAC), RB8514 (delay) and RB8515 (clock) cards
for 2.4 and 2.6 kernels:

Linux device driver and library for the
Meilhaus Electronic GmbH
ME6000 and ME6100 DAC cards for 2.4 and 2.6 kernels. The driver
is an adapted version of an older one (from 2002) supplied by
Meilhaus (under GPL). Please see also the
Meilhaus homepage, they
supply much newer drivers and a library that rather likely is
much superior.

Perl module for file locking using fcntl():
Perl's file locking function flock() usually is based on the
flock() system call which has some known shortcomings and,
in contrast to fcntl(), does not allow locks on parts
of a file. Obviously, this module will only work on systems
having a fcntl() system call. Download via CPAN:

Here you can download free ebooks (in German only). |
Please note: The Linux device drivers you can download above seem to compile cleanly with all 2.6 kernels I tried (up to 2.6.37) but due to the rapid development of the kernel I can't guarantee that they compile on all kernel version in existence. And, since I don't have access to all the hardware under all kernel versions, I also couldn't do tests for all possible combinations. Please let me know if you encounter problems.
