The next time some hardware fails I'll get a Mac. I just bought a new motherboard for my old PC and it took only some 5 hours to get things working again. Now I still don't have graphics via the DVI port, only some not very sharp output on the analogue port. But at least it works and I hope it won't crash that often as the old one did. As for the barebone which I had and where the porwer supply died: you cannot get that power supply anymore. This barebone is less than two years old... Hurray for short product cycles.

[Edit] Finally got the DVI working. It seems that envy is pretty useful if you have an nVidia or ATI card and want to use it with Linux. Also the nVidea settings program is quite OK (you have to run it as root though and the user interface is not really intuitive). So I have now a working graphics output on my DVI port, with 3d acceleration (including wobbly windows and desktops on a cube)

How to print an a5 booklet

You've got a file full of a5 pages and want to print it on an a4 printer so that you can fold it and it will be a booklet:

psbook -s<number_of_pages>

Number of pages is here the number of pages in a stack (normally the number of pages of the document plus a bit that it is dividable by 4). If you are binding a real book, it is the number of pages which will be folded and sewn together.

psnup -2 -pa4 -Pa5

-p is the page size of the output file, -P the page size of the input file.

Print with flipping on the short edge. This is tricky on the command line, but if you print from a viewer this should be easy...

As flickr seems to go the same way compuserve did go back in the early nineties (from a successfull community to a huge coorporate hell which ignores it's users and only focuses on shareholder value, from being great to being bancrupt because they overlooked what it really was they had...) I am now trying some alternatives. There is a good overview of alternatives (in german only though). I signed up at zooomr and 23hq, experiences will be posted here...

[EDIT] This is how flickr treats it's customers... (For those of you who do not speak german: this guy sent a mail saying that he is leaving. He got a response which basically tells him "We don't need you, just f*ck off")

[EDIT2] I also signed up at ipernity which looks quite nice

According to the political compass questionnaire I am belonging to the classical libertarian collectivism of anarcho-syndicalism. I am more left and liberitarian than Ghandi, Nelson Mandela and the Dalai Lama (Economic Left/Right: -5.50; Social Libertarian/Authoritarian: -6.82).

Seit gestern werden für deutsche Nutzer keine Bilder mehr angezeigt, die als 'moderate' oder 'restricted' markiert sind! Es gibt keine Moeglichkeit das umzustellen - das ist eine grobe Unverschämtheit und Frechheit von flickr!

In English:
If your Yahoo! ID is based in Singapore, Germany, Hong Kong or Korea you will only be able to view safe content based on your local Terms of Service so won’t be able to turn SafeSearch off.
In other words that means, that german users can not access photos on flickr that are not flaged "safe" ... only flowers and landscapes for the germans ...
We will not let this happen! Copy and upload this picture to your account - show flickr who we are!

Lade dieses Bild runter und poste es in deinem Account! Lass uns das Bild überall auf flickr verteilen und es in 'Interestingness' heben!! So geht es nicht!

Bikes and Computers

I got a new saddle for my bike today as the old one was falling apart. It has a ventilation system which keeps your rear end cool. Actually quite a nice feature...

I did a short cycle trip to check the saddle, to play with my GPS and to get some training. See picture for the trip, in total 19km.

The power supply of my computer died today, taking the fuse with it. So my living room (where also my fridge is located) was without electricity for some time... Fortunately the fridge is mostly empty. The computer was switched off while it happened, the computer has some fancy display which is always on, so the power supply was doing something. As it smelled quite badly, I think one of the capacities just exploded. This computer had about a year and a half... Hurray for reliable technology. So I am sitting now at my old desktop and wonder why I bought the new computer as it does not feel slower.

Web 2.0

Just returned from a field trip with fellow flickrites to the bergkirchweih... As we talked also a bit about geotagging, I was wondering, if you can include geo-tagged pictures in google earth. Well. You can... So, here is a google earth link of all my photos :-)

Fliegende Kinderscheisse

5. An Age of Confusion, or an Ancient Age, is
one in which History As We Know It begins to
unfold, in which Whatever Is Coming emerges
in Corporal Form, more or less, and such times are
Ages of Balanced Unbalance, or Unbalanced
6. An Age of Bureaucracy is an Imperial Age in
which Things Mature, in which Confusion becomes
entrenched and during which Balanced Balance,
or Stagnation, is attained.
7. An Age of Disorder or an Aftermath is an
Apocalyptic Period of Transition back to Chaos
through the Screen of Oblivion into which the
Age passeth, finally. These are Ages of
Unbalanced Unbalance.
HBT; The Book of Uterus, Chap. 3

It seems, we are now in the Age of Bureaucracy (although today is Boomtime, the 6th day of Confusion in the YOLD 3173). I will go and eat an hot dog as it is friday.
