My first week started quite eventfully. After the day in which I had Thermodynamics, which went OK and in which I learned little new things, I went expectedly to the "Automata and Formal Languages" lecture. There, I discovered that "Set Theory and Logic" is a hard pre-requisite for the course. I talked with the lecturer during the break and he told me that he won't allow me to take the course. I asked him why the requisite was so important and he said that "You see, we have set theory all over the place". But I did not have a problem to understand what I saw in the first half of the lesson!

In any case, I cancelled the registration for this course and registered to a different course from the Electrical Engineering Department on the same day. ("Design of High-Speed Digital Systems") For it I'm sure I have the pre-requisites.

DVD Playing Trouble

I had a trouble playing DVDs. Ogle and mplayer have emitted the error ""Can't open file VIDEO_TS.IFO" and Google could not help me. I then tried playing a music CD, and mounting a filesystem, and neither of them worked. Then it hit me: the ide-scsi emulation! After I switched the device to /dev/scd0 (the SCSI device) everything worked fine again.

Am I lame or what?


I done a little translation of Homesteading the Noosphere, up to and including the end-note about the Fijian Village Chiefs. I also received some corrections about "Rub a dub-dub" which I happily applied.

Subversion and Win32 Guide

I received an E-mail from the guy from whom the guide was intended, telling me he failed to install Subversion once again. This time, he did do a step he did not do before, but he did not follow the guide exactly (and named a URL differently), so this may be a problem. He said he'll try again later, but meanwhile will use CVSNT for the current project.

grip woos

grip ripped at 4x speed, while my CD-ROM drive is 52x max. I posted a message to Linux-IL about it and Matan Ziv-Av replied with a good advice, that increased the speed to 10x. Still not maximum but better.

Welcome to Linux

I ended up preparing the slides for 3 out of 6 of the lectures that would be given in the Welcome to Linux series. Recently I was asked to prepare a version of them that would be viewable from the hard-disk. A quick script did the job, but it took me some time to debug it.

The first lecture was given yesterday by Ori Idan. The lecturing hall was full, many questions were asked, and Ori gave a good presentation. There were a few glitches in the lecture that KDE there got stuck, and so the lecture came out longer than agreed on. I came to the lecture with Ori, and went back with a guy who had to drive to Northern Tel Aviv, which was very convenient for me. He was a Linux newbie, and I told him a lot about what I'm doing right now, about CVS, about software patents and other things.

Perl Golf

The last three days I was heavily occupied with the PERT/Gantt chart conversion Perl Golf. The day before yesterday, I ended up with a 65-characters long solution, and yesterday I was able to optimize it twice, each time by one character. Right now, I'm stuck 6 characters before the currently best solutions, with no ideas on how to further optimize it. But I'm still not giving up.
