First, I got Internet at home few weeks ago, 6 months after moving here. I expect my online presence to get back to a reasonable level :)
I played with NFC on my Nexus S but did not find anything interesting, my Navigo is not seen but people report their as seen, so maybe this is because mine is a three years old Integrale. My oyster card is seen but I cannot access any data: they upgraded to MIFARE DESFire since last year, and it offers real security. Andate Tour card from Porto is a simple MIFARE UltraLight so I can read everything but I would need to go back there to get useful info to decode it, the only surprising thing is that it does not seem write protected...
I also wrote last week a patch for android to set timezone and allowed wifi channels based on mobile country code for many more countries, if it is accepted it will allow people to see networks on channel 12 and 13 in many countries.
On other news, I will be in Paris for a week at the end of the month but will miss Solutions Linux this year. I will however attend Desktop Summit in Berlin in August.
