Shallow and Pedantic

A person/tech/code blog of a coder/techie/person. Like calculus in a kiddie pool, the author of this blog is known to be quite shallow and pedantic.

Valgrind Fail

I neglected to post this here somehow, it’s about a month old by now… Screenshot lost in the mist of time… shows a program segfaulting, and then working properly when run within valgrind. The problem turned out to be an imprecise (false-positve) comparison operator implemented for a class used as a hash key. God, I hate C++.

Scheduling

So, I see I forgot to post my schedule for this semester… …ttime screenshot lost in the mists of time… As you can see, it’s TTime! With a shiny new Cairo interface. We’re back to the Ruby version, too - as we have another coder on board, which is using his compilation skills in order to write a new REPY parser. You can also see it’s only found one schedule. This is thanks to the group selection constraint which was finally coded.

Things I learned today

You can use git on a VFAT disk (for example, a USB key) without all of the annoying mode issues, by using the following setting in .git/config: 1 2 [core] filemode = false What I haven’t figured out is how to do force a chmod in this situation; for example, if I create a new script, I was hoping to be able to git chmod +x it. Cream is a very good editor if you’re used to Windows applications.

Deskbar and Firefox 3

Deskbar has a really neat plugin which allows you to search your browsing history and bookmarks. Firefox 3 has switched the storage format to an sqlite-based one. I’ve been working on a new plugin to make use of that - so far it’s very enjoyable to use :) ยป Deskbar_FF3

Hebrew spell-checking in Pidgin

This one took me a while to figure out, which is reason enough to post it here. First of all, you’ll need aspell-he, as pidgin uses gtkspell (which, in turn, uses aspell) rather than enchant (which supports hspell). There is a patch for gtkspell which gets it to use enchant, but I don’t know of a simple way to get it to work in my distribution of choice, Ubuntu. Now you need a neat little plugin from the Guifications plugin pack, called SwitchSpell.

Faster Languages

Due to an exercise in an AI course, I’m forced to confront an old nemesis - C++. Part of the reason is that the exercise contains a time-limited tournament, and the code needs to run very quickly. Another reason is, I guess, the fact that C++ serves as a sort of lowest common denominator in the course (which used, by the way, to be taught in LISP, along with the language).
