Dealing with algorithms and data structures

One of the rea­sons I haven’t been writ­ing on this blog that much lately is that I’ve been ter­ri­bly busy with uni­ver­sity given that I just cleared out six exams in six months. That said, for one of my three exams that I still have left, I had to develop an infer­ence engine writ­ten in C++. Since this was a fairly large project that had to deal with some sort of NP-​complete prob­lems (see also: uni­fi­ca­tion) and given that this was the first time I wrote some­thing seri­ous in C++ (i.e.: that would involve more than a class and that didn’t con­tain the “Hello world” string) I had the chance to learn quite a few new things.

Optimize your programs

The last time I blogged about a new course I’m fol­low­ing at my uni­ver­sity. This course, held by Pasquale Lops and Gio­vanni Semer­aro, is very inter­est­ing at the point that I’ll be devel­op­ing a custom infor­ma­tion retrieval engine as part of my intern­ship project. I can’t tell much more at this point since the intern­ship haven’t started yet and I’m not sure I can release more details about this project (we’re still in the process of decid­ing if and how the whole thing will be released to the world).

In the mean­time, I’ve been doing sev­eral exper­i­ments on this topic mostly about the memory usage and the per­for­mances of such system on lim­ited hard­ware. This prac­ti­cally means imple­ment­ing the algo­rithms you’ll be using and mea­sur­ing the com­pu­ta­tional time they require.

And djangodash is ended…

And I’ve been 6th. So I won a shared 2 host­ing plan at web­fac­tion and a 12 pack of G33K B33R caf­feinated root beer (still trying to under­stand what this is exactly, anyway) from bawls. Anyway, here fol­lows a short resume of what hap­pened from Sat­ur­day through Tues­day (if you’re asking your­self why it didn’t ended on Sunday, well, keep reading).

The com­pe­ti­tion began very well, I worked nor­mally for the first part of the day but then I had to stop for a while. When I came back, svn and djan­go­dash web­site was not work­ing any­more. I ini­tially thought that it was some con­nec­tion issue but when I saw that other sites were work­ing prop­erly so they def­i­nitely had some problems.
