Spontaneous combustion

flagpole Tian'anmen Square

It seems there have been some incidents of spontaneous combustion on Tian'anmen Square, so they figured they'd better be safe than sorry.

A day in the Forbidden City

 

Electronic guide at the Forbidden City in Beijing, before and after (4 1/2h later). Red dots show places I haven't been. But I'm sure I hit one or two of the places without the guide kicking in. It seems to be using GPS or some other trigger. For around 10 EUR, I could actually have taken it home and dissected it ;)

Going to Kuala Lumpur for the weekend

Tomorrow we'll be leaving for a few nights in Kuala Lumpur. The weather forecast suggests rubber boots, but we'll see... Hopefully we'll be able to hook up with Zuzana and her friend whom we met on Mt. Kinabalu last year.

Please wash your hand before you leave


I found this in the washroom of a restaurant for handicapped people.

IPv6 experiments, cont'd

I've finally found some time to play with the local tunnel broker from HE at Tunnelbroker.net which has a POP over in HK. Neat, I hope we can wire up UNU-IIST eventually :)

A hole in the Great Firewall of China

IP adresses slightly obfuscated to give the local hackers a chance. I guess sooner or later the admins will catch up and plug that hole as well. I was pleasantly surprised, +1 for IPv6 by default -- thanks Apple :).

In related news, my presentation at the NPC had to be cancelled, security on Tian'anmen Square was too tight, they had security check points at all passages and I didn't feel like providing the back drop for how civilized Peking is. The amount of police (traffic police, normal police, military, plain-clothes officers) was creepy. Also occasionally people in front of the gate got wanded, or their bulky stuff inspected. But I gave a presentation at the Institute of Software of the Chinese Academy of Sciences, and Zhiming gave the presentation at Peking University.

National People's Congress

From tomorrow, I will attend the 2nd session of the National People's Congress in Peking. I will give a seminar on the rCOS modeler and try to recruit a student or two to visit our group. I just hope that this NPC-thing doesn't affect our travel. By the way, Chinese airport security is much friendlier than the usual underpaid (hopefully) security-grunt in Germany. But hey, that's not that difficult.

I'm glad that I know Naijun already!
