Friday Night

Wednesday and thursday where only university days. My robot can walk now from A to B and reacts properly to simple obstacles. But he has a problem with bigger obstacles. Those, who are interested in it: I covered the pathfinding algorithm from the algorithm for Bresenham-lines and added some simple reactions to obstacles. But I think I have to redesign it, because of the big-obstacle-problem. He needs a memory where he has already been on his path and he needs to calculate the path before he starts to walk on it.
On friday I did nothing special. I phoned StuBo for moving to 16B, I could only speak on a recorder. Better luck next time. I also contacted my home university for some bureucracy stuff. I guess this will never end until I would leave Germany. Not that I plan to do it (I hear the rumors arising again). But I hate this German behaviour first to think about rising for denying service. For my financial support from the state, I need two applications from the university. But the department of my university pretence for not knowing me, because I am not listed on a paper. Instead of looking into the computer system they send my brave Hans (thank you!!!) away. In Sweden it is totally different. I can go to several offices at the university asking applications. They are connected to one central system and have all information they need to help me. The biggest difference to Germany: they want to help me.
In the evening Nawelle invited me to a baskelball-match. Sundsvall has won against Öresund, but I liked Öresund more than Sundsvall. They commited less fouls and played with a better technique. Afterwards a private (salsa-) party started at town. A salsa-lesson was included and Julio, our teacher, had a lot to do. I did not participated the exercises, this time, but I am looking forward to next thursday where the advanced course starts. I can only remember the basic steps. Julios friend made a "punch". I thought it is a punch, but it was more related to the german word "panschen". It tasted well, but after I have seen how it was made I did not want anymore. It was wodka with juice. Alright. But it was also the rest of forgotten beer cans and what ever was standing around in the kitchen. Bon appetit.
Today I slept very long unwilling to get out of my bed. Tonight I will have my second swedish partylife-experience.

Hey Markus.

Ich weiss zwar nicht was "Bresenham-lines" sind, aber hat du fuer deinen routen planer mal A* search gedacht?

Der kann dir wirklich schnell einen weg van A nach B planen, und es ist auch einfach zu implementieren. (Am besten mit Manhatten distance als under-estimate)

Viel spass damit
Maarten
Es gibt einen Bresenham-algorithmus zum Zeichnen einer Linie. Für straight-forward Wegstrecken ist das ausreichend.

A*search haben wir erst diese Woche gelernt, der Roboter aber schon längst eingereciht. Ich weiß aber auch nicht, ob der Simple-Agent mit so einem Algorithmus nicht schon überqualifiziert gewesen wäre ;)

Aller guten Dinge sind drei

On Friday we had a party at Norrmalms. And because the party room looses power at 12pm everybody had to bring candles. Cool idea. In the morning I felt a little bit dizzy. I guess, due to Matt's Whiskey-Coke. At a Whiskey-Cola by Matt Coke is only used for giving the Whiskey a slightly darker color. On Saturday we have been to Kårhuset the first time since weeks, because Marcolino, Thomas and Jens were working there for the first time all together on one evening. And surprisingly the party it was very good. First we conquered a private party at the upper floor. It was meant for some Swedish students, but they were already drunk and not caring about who enters the dinner room. And they had a cool Live-band who played only good rock. They stopped at half past 1 and the last two hours we sticked to the usual dance floor who did not have the usual annoying Swedish chart music. I cannot recall what they were playing, because most songs I did not know, but it was funny. Somehow, this se...

För den jag är

Unbelievable. Anna is already since 10 days gone. Or is it only 10 days? I lost my feeling for time. Everyday is full of experiences and activities. I cannot recall everything what I have done in the past two weeks. Many things are just small things which I appreciate a lot. But the last weekend was a highlight. We went with 12 people in three cars to a place called Vallbo near Åre. We started at half past 6 in the morning on Saturday. Although some of us did not sleep at all during the fromer night we walked almost 8 hours. And it was awesome. We walked through so many different landscapes. Wood, swamp, high gras, Tundra, stone desert, climbed up a mountain, walked crosswards through the wood, on a dead river... Overwhelming. I remembered pictures of New Zealand while we wandered through that panorama. The view was breathtaking. The weather changed quickly a few times. One we had even an ice shower. In the end of the day we stayed for dinner at a pension where we got selfmade soup, b...

First week

Now it has been almost a week since I came back and I remember why: because of the summer. It is the most beautiful season here. And I tried to take advantage of the weather. I got a new bicycle for I changed my small blue one with Anna's big yellow bike. Funny, it is the same modell as mine in Germany - just bigger. My first ride was to Sidsjön two days ago to have a picknick there. The day after I repaired the brakes and today I bought a new lock and oil for the chain. This evening it rained and tomorrow shall be the ugly weather, too. I want to try to use the next sunny day for a small tour. Probably the road along Sidsjön out of Sundsvall.
