My place to post silly pictures and rants, even though I’m no longer a PhD-student.

Again, trainstation at night.
After watching this space for a while you will inevitable come to the conclusion that I really like taking photos at our trainstation. Please let me affirm this suspicion with this post.
Playing with the layout.

Studivz
If you want to register at the Student's Registry (which was sold for €85M to Holtzbrinck recently!) you are presented with this registration form. Up to now I assumed, that someone who graduated from university should be able to distinguish between surname (Nachname) and given name (Vorname) without further help?

integrated circuits and envelopes
We ordered samples from Analog Devices before christmas, today they arrived. We are happy about that, of course, but they arrived with a little exaggerated packaging. The two chips (one SO-8, the other a little bit smaller) came each in a piece of PVC tube (the SO-8) or SMD-reel, packed each in a antistatic bag and put in a seperate padded envelope, about A4-size.

Long-term CDR storage
For testing a external USB DVD-burner I needed "something" to test it with. That brought me to 2 packs of CDR-blanks that have been laying around here for ages, I think they have been bought when my trusty old Yamaha CRW4416 x4-Burner I'm using until now was new. That makes them about 5 years old? Well... those CDR blanks were still in their original packaging, with the plastic foil intact. But they looked quite interesting, with a dull finishing and something that reminds me of frosted glass-windows.

Playing with old junk, episode 756412
I found a nice a old HP 82240 thermal printer in the cellar once. You can use it to print stuff from those pretty HP reverse-polish calculators like the HP48. Unfortunately they only speak the proprietary red-eye protocol over infrared so I had to resort to a little bit of hackery using a Atmel Tiny2313 and a IR-diode... And now, it prints! :-) Hooray.

Entering numbers
We are ordering lot of things (clothes, books, kids' toys) online. Which leaves me with the task of paying the bills found in the parcels. That's not too bad because I can do it onine. The only thing that annoys the hell out of me is transcribing all those numbers (account, bank, customer, invoice) from the paper copy into my web browser.
I don't have anything against typing numbers in general, but why don't they group them e.g. by 4? With hyphens in between? Most likely because the wise programmers of the severly fucked up web-frontend to my bank decided that anything but numbers in most fields is a bad thing. Therefore don't even allow such a readability-increasing method in their various number-eating input-boxes. Oh, and please somebody explain to me why a invoice number has to be 15 digits? Especially when paying a bill from a relatively small german publisher who - for sure - has less than 1015 customers whom to bill. Suddenly typing in microsofts 8x4 character license keys does not look like a bad amusement at all.

T400
I inherited a interesting looking old ISA card. After closer inspection it appears, that it houses a INMOS T400, a Transputer CPU! Absolutely fascinating and unfortunately utterly outdated.

Election Computers
Wij vertrouwen stemcomputers niet have analysed the election computers that are used in the netherlands and found out that they have a huge number of security flaws. Their great publication is a very detailed description of all the shortcomings they found up to now, it shows some possible attacks they have implemented and describes few more that are now known to be feaseable.
Those machines are basically a overpriced version of the Amiga 500, with less RAM and without the nice sound and video capabilities -- in a huge box. There is not a single feature built in to try to counter vote forgery, it's really just a plain 68k computer without any cryptographic or trusted-computing capability.
Those voting-machines are very simmilar to the computers that are used in some regions of germany. Of course they have been thoroughly examined; in germany (where I live) by the PTB which is responsible to maintain precise clocks (a task it does very, very good) or to provide standard-weights so that scales at the grocery-store measure the correct amount of vegetables you buy. I'm sure our election computers are really precise in this regard.
It's noteworthy that the german BSI (the authority for security in information processing, who really are knowledgeable about computer and IT security) have not been ordered to evaluate those computers (who said bribery?)! And of course the report on the test done by the PTB is confidential not to compromise the valueable 1980's technology trade secrets of the supplier. What a joke.
In the Netherlands they have been checked by the authority responsible for the safety of cars or electrical installations in bildings. No one will ever get a electric shock or be injured by a hard edge on those machines -- correct counting oviously was of no concern to the testers.
The computer magazine c't recently had an article about that e-voting-mess in general (issue 16/06, page 54), and after reading few reports about how that works in the USA I honestly was not really surprised about what the dutch hackers had found out. Maybe that's also why I quicky got distracted from studying the NEDAP-hardware to find this little gem:

More video surveillance
After the attempted train-bombings here in germany, our minister of the interior promptly declared that he had already spoken to the representatives of the german bundesbahn to have the number of cameras in trainstations increased. This is done, so that we can catch more of those TERRORISTS, of course. Now obviously this plan has been carried out already, because since the last time I visited hamburg the number of cameras on the S-Bahn in Altona and Sternschanze has doubled! If you look more closely at the camera housings (those photographs are so shoddy, you cannot even see the label :-( ) they are clearly marked as "camera 4" and "camera 4 (redundant)". I feel much safer already.

Composite Sync
Granted, my VGA connector now looks a little bit odd, but finally it sends something looking almost like a good composite sync signal onwards to the CRT.
And it's good enough to persuade the monitor to display something (and not just turn off and going into power-save-mode).
Finally, no more tiny icons and blurry text on that old and crappy 17"-tube. That makes me happy.

Desert Climate
Because of the hot weather here in germany, the HERA accelerator has problems dissipating all the heat the overdesigned and energy wasting machinery generates.
All provisions to reduce the cooling-water temperature have been exhausted. Feedback transmitters are off, circumfence-voltage is down to the bare minimum and the HF-power has been moved to the west . Mr. Hurdelbrink has (developed?) operation-modes for winter and summer, but not for desert climate.
