I’ve been attending, and talking at Toastmasters recently. It really fun and I’d recommend it to anyone who has a problem talking or just enjoys hearing other really good speakers. There are 6 groups in Munich, some English, one French, an Italian and some German mixed with English groups. Here’s an example of someone speaking:

Should anyone ask, all cats need a ladder
I came across this strange ladder while looking for a flat in Berlin. I guess my priority of living higher up needs to be down rated.

Should anyone ask, cats make excellent French teachers
I found an instructional guide on my webserver. Guess they have been busy setting up their language school.

Should anyone ask, traffic prioitization should be done one the edge of your network
I spent some time today experimenting with traffic shaping on ddwrt. My VOIP calls were still stuttery due to packet congestion. Although this time I traced the congestion back to my wireless bridge. Good thing it runs linux and I was able to install the following script. It simply prioritises packets in and out of my wireless gateway on both the wired and wireless interfaces. This is nice because people I call will no longer hear a stuttering or voice drop out when there are large file transfers going on. It simply creates 3 queues (mobile, laptop, all other) on both interfaces and sets up a simple prio between them. All classes are guaranteed at least 200kbps (should the wireless connection be really bad and the PHY drop down to 500k. But the beauty of the HTB shaping model is that it will borrow. So in this case classes (laptop and “all other”) can borrow from “mobile” when they need more “tokens”. IE the right to transmit a packet.
Did I mention DDWRT was cool?

Should anyone ask, I was in Berlin, again.
Returning from Berlin. I have just spent the last 4 days in Berlin. 3 of those with my mother and the last walking around neighbourhoods to find something that I could possibly live in. During that time I have seen 2 great film.
Even though it was the Berlinale, these were ones from my “To be viewed” spool. Most recently I finished watching Luc Besson’s “Angel A”. Wow. I was in Paris last month and this brought back many memories. A large portion of the film takes place on the graceful bridges that span the Seine. The story is about a down and out scamster being put back on his feet by an angel. The fact that this Angel A aka Angela is at least a foot taller than him adds to his depression. The film is shot in black and white with some excellent lighting, particuarly where the main character addresses his deamons (those that that keep beating him up on the street, and to whom he owes much money).
It was Berlinale and I never made it. Although I did make up for the time by meeting Nataša who organises the Croatian equivalent and was here to snag as many films for the next showing in Zagreb. When not talking about films, we exchanged memories of our times on the island of Vis.

Should anyone ask, we need more unregulated spectrum
It’s getting crowded around here in the 2.4Ghz spectrum. This is in the middle of the day – in the evening about 5 more access points show up.
