The weekend was to short. During the first days I always have to remember Östersund. On monday I had a predicate logic lesson. Until now I can follow the lesson. The lecturer started to express everything in mathematical formulas, so can finally learn that, too. Yesterday we had swedish lesson. I like these lessons. Ella has prepared something, but we have everytime something else to question. Yesterday we brought a article about Anna from a magazine. During the lesson we read the article and discussed it. And because it was full of partizipels Ella taught us partizipels. Today Basti and I had our first Decision Analysis lesson. Because Jim became father another lecturer taughts the lessons. Aron makes his job fine, I think. He tries to involve the audience and explains everything in details and with funny examples. But one thing I don't like: as always at this university you need a course book. And as always there are just two copies at the library. And the bookstores have to order the books first and it will cost 500 SEK (more than 50 euro). And we have to do exercises from the book. But until now, we have none, because the books of the library are loan and we don't know the persons who have them. And the bookstore is to expensive. And the amount of exercises is very high. At least we have time until 21st of january.Yesterday I started converting the recursive variant of my RSA algorithm into a iterative version with an implemented stack. It did not work for all problems and after hours of searching I found the error at midnight. Today I will fix it. After that, I will implement a serializable stack for time driven backups for if something happens to the computer during the calculations. I hope, I can start the first test phase this weekend. Because I also want to implement a window for visual feedback, I should be able to post a first screenshot soon, so you have an imagination of what the nerd here is talking about.
