My Addresses (University and Private)

Speaking of addresses, I finally managed to get hold of a domain of my own (before 2000!) - proudly presenting www.haenssgen.de :-)
(sth.de was taken already, yuck :/ )

My Son :)

May 6th 2002 - Tobias Philipp Hänßgen... enter the Multi Media Archive! (in German, but the pictures and movies are universal, and until he's a bit older his words aren't that much recognizable as German anyway :)
Requires a password to enter, just ask me - it was a bit annoying to take a look at the Apache logfile and see 1001 folks I don't know looking at pictures of my son (some very interesting referer tags from search machines).

My Wedding

September 1998: Ulla Vierling + Stefan Hänßgen -> Ulla + Stefan Hänßgen... here are some Pictures

My PhD Project

REAPAR - Automatic Parallelization of Irregular Recursive Programs
You can read my dissertation online (in German) thanks to the University Library's elecronic publication features.
The results of Niels Reimer's Master's Thesis on Dynamically Adapting the Degree of Parallelism with Reflexive Programs, which I co-advised, were accepted as a paper for the Irregular'96 conference.
I'm also interested in the WWW and Revision Control, leading to the WWRC project.

My complete list of Publications is available, too. You can also take a look at my Curriculum Vitae (in German, not very much up to date any more).

Pictures of my PhD Defense in April 1998 (warning, rather large)

ACM Student Chapter Karlsruhe

I used to be chairman, vice chairman and secretary, with several ACM Lectures and programming contests etc. Since my PhD I've passed on the chairmanship and am no longer actively involved (the curse of normal work life: no time for nothing...)

Here's some additional information on ACM, Student Chapters, and the benefits (in German).

Internet online

I've been co-founder and vice editor in chief of the German Internet online magazine - always looking for interesting ideas or articles all around the Net. Feel free to mail me if you have suggestions or want to write an article on some Net-related topic you're expert in. (The magazine itself has been cancelled in mid-97, and the name and domain have been sold to another magazine, but we're still working as freelance writers)

Consulting & Training

In spring '96, my scholarship ran out, so I've been financing my PhD by freelance IT consulting and training, quite successfully in fact :) If you need a consultant with more than 11 years of practical experience in areas such as UNIX, C, Internet, Lotus Notes/Domino, Client/Server computing, organizing and implementing projects, etc. just give me a call!

Since 5'1998, I had been very happy with my "regular job" at the GINIT Group and had reduced (but not abandoned) my freelance activities accordingly... however, the whole GINIT Group has gone bankrupt, killed by the stupidity and lust for revenge of its Co-Founder, RIP.
So now I'm a freelancer again - feel free to take a look at www.sth-consult.de for a list of my services, mv CV and my skill profile :)

My Interests

(Warning - overuse of smileys in the list below!)

Reading - Science Fiction & Fantasy, preferably in the English original
Roleplaying - sometimes Midgard but mostly ShadowRun
Star Trek - not an extreme Trekkie, but here are some nice cardboard models (formerly on Oli Götz's homepage)
Computers - I used to brag here about my PowerMacintosh 7300/200 ("don't trust anyone with less than 192MB, a G3/400 card and a Voodoo3 ;-)") but that's not toooo impressive anymore. Even the PowerMac G4/867 with 1GB of RAM and a GeForce 3 and a nice 17" Apple LCD display isn't, so I sold it and got myself a nice dual 2.5GHz PowerMac G5 with 1.5GB RAM, 2x160GB SATA drives, Radeon 9800 XT with 256MB VRAM, the works...
Also, the old Psion 3mx had given way to a Psion 5mx Pro (right on time, when Psion was leaving the Hardware market, yuck...), whose screen connection cable broke in 2004 so I got myself a Palm Tungsten T3 now - amazing how advanced the Psion was in comparison, real multitasking, good keyboard... not everything is getting better with time it seems.
My Computer Musum now includes: A PowerMac G3/266 beige (with Sonnet G4/700 upgrade, 640MB RAM, ATI Radeon 7000 PCI with 64MB VRAM, Sonnet Tango Trio with USB2.0 Firewire and ATA-133) which serves as my router/firewall and runs MacOS 10.3 very nicely, a PowerBook G3/266 (192MB RAM, still quite useful since it has all the legacy ports - serial, ADB, SCSI, PCMCIA etc), a dusty Atari ST, a PowerBook 540c (upgraded from a 520), a Mac IIci (16MB and Cache Card for super performance, well, at least that's what was really really fast in 1990!) and three fully functional Apple IIs (!) and a Mac Plus and ... you get the idea ;-)))
Music - I used to play the Electric Bass Guitar, quite some time ago. A bit unrelated but also noisy - here are my login/out sounds
Computer Song Collection - I collect computer related song parodies. Here's the text version (336k) and the compressed text version (gzip, 118k). There now is also a nice HTML Version by Jenny Preece which has some more songs than the text version (have to update that list some day...)
My friendly Mensa Daemon (with complete HTTP support!) can tell you what's on the menu in the University and Fachhochschule Mensa. He only speaks German, but fluently 8-)
now defunct, the machine it used to run on no longer exists :-(
I collect postcards. Currently, I define my collecting interests as "scenic cards from all over the world, monuments, art, comics, fun, anything unusual", which covers about all possible types of cards... well, send me one and I'll surely send you one back :-) [my turnaround times have degraded a bit lately, but I promise to reply sooner or later ;-]
.. and WWW of course - this homepage exists since October 1994 (now beat dis :) and I'm online since 1987 (VAX running VMS, managed to get international EMail access for the students back then). Hey, don't call me NetGrandPa ;)

Some local Links Institute page (in English), Department page (in German), University page (in German). Send me a Mail (in your favorite Language ;-). Get my PGP public key.

(Yes, this page could be much fancier, but I have better things to do ;-)

(since everyone seems to have at least one animated GIF on their homepage, here is my attempt at meeting the standards - no idea where the original came from :)
