Flickr did spawn a lot of community contributions. While I save all the extensions, hacks and tools for another post, today I want to present you pictr*e magazine, a free, creative-commons "offline pdf mag with photos and stories from flickr". The first issue features some outstanding photography, an interview with Jeff Clow (from the 1-2-3 group) and the Lomo fake effect-technique tip.

Das Yo!Einstein-Forum hat jetzt einen eigenen Troll. Sehr witzig zu lesen (wenn man sonst dort nicht aktiv ist). Mich wundert es nur, dass früher noch niemand auf die Idee gekommen ist, die angesprochene Altersgruppe ist ja prädestiniert dafür… Vielleicht liegt es daran, dass niemand das Yo!Einstein (vor allem das Forum) jemals richtig vermarktet hat.

"My homepage. After being on the Internet for a good decade (and good it was), I decided to get me one too. It does sound really circa 1996,"

but it is not. Douwe Osinga has but together a very interesting assortment of is projects and (mainly Google) hacks. Most of his work is either about statistics and data mining or artifical life.

He does some interesting things with the Google search engine, like letting it talk (this goes a tiny step in the direction of an idea Johannes one suggested to me). You will find plenty of things to explore at

nice surprise

Posted this pictures yesterday evening and was overwhelmed by the response to it when I logged in this morning. 10 comments, 7 favs, 130 views and 4 persons who decided that I’m worth being watched.

Though I take most of my flower-photos just for recreational (while studying or working it is nice to have a break and go into the garden with the camera) and learning (technics and composition) purposes, it is good to know that this pictures also make somebody else smile.

A friend of mine suggested this link (or rather showed me a printout of this site, and I had to google for it). "The Devil and Simon Flagg" is a mathematical short story by Arthur Porges. It is now a bit outdated but the conclusion is nowadays true nonetheless.

Not only Google (and Microsoft) can deliver satelite photos. NASA can too. Its World Wind application does even predates Google Earth by quite same time. While for many regions the NASA data has a worse resolution than Google’s, World Wind has acces to the newest data from MODIS and does also offer overlays from SVS. The first means, that you can see current intersting phenomea like hurricans, sand storms and volcanoes, the latter offers many overlays of the globe showing everything from sea temperature to signs of human inhabitation. It has also the undeniable benefit of eing Open Source and having a community.

A realated link is NASA’s Visible Earth site which offers quite a lot of stunning statelite imagery. (Good for making posters!)


Schön langsam wird das TUWIS (Informationssystem der TU Wien) ja benutzbar. Da gibt es jetzt die Vorlesungszeiten als ical und vcal zum Herunterladen und in die Kalendersoftware (zB Evolution, Outlook, iCal) Importieren. Noch praktischer wäre natürlich webcal, so dass die Daten immer automatisch am neuesten Stand sind. Und natürlich wäre es auch ganz praktisch, wenn die eigentragenen Daten stimmen würden. Aber immerhin ein Schritt in die richtige Richtung (bei anderen Unis soll webcal und so ja Standard sein). Hoffentlich wird bald was aus Hula.

Which is kind of sad. But on the other hand there is a lot I am looking forward to in the next semester. Some intresting lectures (algebra, number theory, set theory, introduction to computer science (for mathematicians)), some conferences (AbiTuPhys, AbiTuMath). Sadly, the first sign of the comming semester is the exam in statistics and probability (which I’m not very fond of..) and I am currently not in the mood of learning something that does not interest me so much — and there are so many distractions, like playing Guild Wars. At least I did start: Searched for the script and put it on top of all the other things on my desk…

I finished reading Hesse’s Steppenwolf. Though, as the auther himself notes in the introduction to my edition, the book was written by a fifty-year-old for fity-year-olds, I think I did understand at least parts of its intention and learned something from that.


In an attempt to excuse me from studying, I started to experiment with MediaWiki and I am in the process of transfering the data from the wiki at to it. I do not know yet how to exactly integrate MediaWiki with the existing structure of, but the current wiki has to go, because I will never undertake the useless exercise of programming all the unimplemented functionallity it still needs.

Today I do not have one link of the day, no I have two!

These two sites will supply you with an virtually unlimited amount of Sudokus in all difficulties: Daily Sudoku and Web Sudoku. And when you really have too much spare time, try this one.

New Design

When I installed plog (the software behind this blog) I chose the blufil template as a temporary design until I had the time to create one myself. So, more than a year later there it is now. Very simple, but hopefully also very clear and useable. Forks fine in current Firefox (1.0.x), Internet Explorer (6.0) and Opera (8). IE 5 has only slight errors, IE 4 and Netscape 4.7 suffer from severe CSS-misunderstandig but should be useable. Sorry, I currently cannnot test Konqueror and I do not own a Mac. If you have problems with your browser, found a bugs or have suggestions for impürovement please let me know.
