The first three Buffalo Source Cd's arrive

As it was to be expected from the previous performance of Buffalo, those three CD-R's contain anything but the "complete corresponding source code" for the requested product firmware versions.

I'm going to consult my legal advise on how to proceed.

Problems with RFID sniffing due to bad driver?

I've now started to write some code for the ICAO MRTD LDS and PKI. If you know what that is, stop reading here. If you don't know: It's the crypto and data structures that are going to be present on the new "RFID passports" that will be issued in Germany (and elsewhere) soon.

Nothing seemed to work. Then it turned out to be a driver issue with the Omnikey 5121 proprietary Linux driver. Did I tell you that I hate proprietary software, especially drivers? Well, I'm on my way to re-implement that driver (actually, a generic Philips RC632 driver), too. But I better wait until it works before I start to re-implement the broken one...

So getting back to our RFID sniffing tests, I think the card was probably not even transmitting as expected. All the responses we got from the driver were bogus. This obviously results in no sub-carrier being broadcasted, and would explain why it was impossible for us to catch it in the spectrum analysis.

I'm off for Wave Gotik Treffen 2005

After a break last year, I'm this year again vising WGT.

I'm a bit curious on how much I'll be able to enjoy it. For one part, the weather is anything but nice. For the other part, the bands this year seem a little bit less matching my taste than let's say two to three years ago. There seems to be an increasing trend towards 'goth metal' 'nordic metal' and the like :(

Anyway, I'll try to not be preoccupied and enjoy myself. I guess this is also the first time for years that I'm travelling without notebook for four days... so expect even more delayed replies than usual.
