Game Player Released A Good Night of Sleep Ah, those Linguists There is a broad consensus in linguistics and machine learning that PSGs [that is, grammars generated by pushdown automata] are more powerful than FSG [i.e. grammars generated by finite state machines]. A broad consensus, naturally, because some would disagree... (??) One wonders: if it's neither the linguists nor the machine learning folks, who is it, the logicians? :-) There is also a broad consensus that 2 is greater than 1, but one must be careful with such things. ^ TOP Watching MeI always feel like somebody's watching me Who's playing tricks on me I always feel like somebody's watching me See this blog post. If you know what xeyes are (and you have the requisite amount of geek in you), this is even funnier. ^ TOP Game Player CodeJocular will be the "parent" of Paulatim, the starter code I'll be releasing to the CS 227b class. Paulatim is Latin for "little by little", which I think is fitting given that the code will be distributed piece by piece to the students as they work on their projects. ^ TOP Linux: Death and Back Again After about 4 hours of messing around, searching and so forth, I realized that other people were having a similar problem. The common denominator seemed to be Beryl, a desktop appearance enhancement (providing both eye-candy and functionality such as something similar to Mac's Exposé). OK, I disabled that (after searching long and far to figure out where the file was stored so I could do it from the command line) and things started working. It turns out that the culprit was a xserver-org update that I had done two days before (without rebooting the computer). Apparently it did something weird to the nVidia drivers, explaining why it crashed when loading Beryl and why the video got corrupted. The "simple" fix was to reinstall the drivers. If only I had known to do that in the first five minutes... The lesson I learned is to always reboot from now on after important system updates. The problem was that I'd completely forgotten about the xserver-xorg update, and so didn't think to start searching there. (Obviously I was looking through the xorg logs, but knowing it was the update would have helped my google/forum searches.) ^ TOP |
