random stuff

Beep, beep! I'm still (more or less) alive.

University takes me lots of time, which is my primary excuse for not blogging
for so long time. Projects are like gas - they fill up all available space^H^H^H^H^H time.

Interesting (for geeky enough definition of "interesting") stuff I've done recently:

  • Spellchecker. It's a quite smart one -- written in python and C, it uses trie (ternary search tree) for storing dictionary. It's super-fast to load data (there are no pointers, so loading it is just one read of binary file, and you can use it).

    Then you can use TST to quickly (it's quicker than hashmap) check if a word belongs to vocabulary or retrieve (it's still bleeding fast) a list of words that are no further (in Levenstein's (edit) distance) than misspelled one.

    Then it uses longest common subsequence algorithm to get parts that don't match and compares those parts using knowledge about typical spelling errors in Polish. It can correct "grzegrzułka", "zomp" and "fzhut". In summary: it's cool.

  • I'm preparing a talk about scala. It's work in progress. You can see some slides here. I'll give this talk on 3th December as a part of BIWAK

  • Oh, yes, BIWAK. We (BIT science club) have started a series of talks called BIWAK.

  • Oh, yes, science club. I've done some work on platform game with cool physics, but there is nothing cool to show off yet.

  • I've published some of my .rc files

  • Hooray new swimming pool! Hooray hiking! Hooray birthdays and weddings. Hooray real life.
