I've found a very cute way to work with integrals like\int_{}^{}P_n(x)e^{ax}dxBefore I always integrated it by parts, for example:\int_{}^{}xe^xdx=xe^x-\int_{}^{}e^xdx=(x-1)e^xIn case you need to take by parts only once it's ok, but when Pn(x) is x^2 or higher degree you need more time to integrate by parts several times.There is another better way, let's take above integral again:\int_{}^{}xe^

Some time ago my stereo died, so I started to use my PC as alarm (I like to listen some music during wake-up). For some time I used it in this way:echo "mplayer -ao alsa -shuffle /docs/music/unsorted/*" | at 10:00"-shuffle" option makes mplayer to play files in random order.Everything worked fine, but some time ago I didn't here my sweet alarm. I wasn't able to figure out the reason, so asked at

Now I'm back. It was a very hard year for me, but now I'm better and do everything to keep going.To raise my spirits I've done two things:I've bought eivanov.com. It will be used as alias for this blog until I have something special.Installed SyntaxHighlighter, which should be useful for posts containing snippets (see previous post for example).

First I started to use WinInet. God, it sucks like most Windows API. I played about a day with http://support.microsoft.com/kb/165298And I failed to post anything, from what django could make request. Aslo wierdshark shown that MS does a bit strange request (it looses some header about multipart form-data).Today I took libcurl, it has a rich example who you can perform your POST-request.Note,

Yesterday I got much pleasure implementing DatabaseStorage class for django. Nothing special and a very simple thing, but I like it: http://www.djangosnippets.org/snippets/1305/Thanks to python and django developers for marvelous duet: python and django :) It really rocks and doesn't have boundaries!

I didn't write anything for some time, since was very busy with my work and family problems.But today I have some interesting thing about django, so I can't keep silence (I'm new to python/django, so it can be interesting for newbies only, but I hope it is not).First of all I want to say sorry for indentation in quoting blocks... Will fix it later...In django to define ManyToMany relation you

Next week I will have to implement something to transfer files between computers. I decided that http transfer could be a good idea, because clients would be able to get files from another sources and not from my server-application only.So here is libmicrohttpd by GNU. It supports SSL/TLS, and licenced under LGPL (which is important for my company, since they don't know what licence will use).

Just finished watching Antitrust movie (aka hackers 3). It's really amazing and it's worth to watch this movie. I remember there was similar story about lawyer and big company (maybe even two stories), but this one is about software development: you can see Unix systems running on movie's computers, Open Source hackers, and M$ (Titled "Nurd" in the movie).But it's really interesting how much open

Unfortunately GSoC has finished. It was a wonderful adventure: I got new friends, wrote some code (~8350 lines counted by "wc -l", so it includes all crap) and learnt new interesting things. I can say that after today's commit to my git repo (with a lot of changes to yesterday's commit, which is evaluted) I implemented all things I promised. But some things still require a lot of love.I want to

I had a lot of non-development problems, but this week I continued to develop my GSoC project (it's the last thing, that can be evaluted, but improved — yesterday's code is very buggy xD).So here this thing is:The only thing to implement is branch labels.Current implementation is very dirty, but it works, the code: http://repo.or.cz/w/kdevelopdvcssupport.git?a=blob;f=plugins/git/gitexecutor.cpp;h

Was offline for a week (or even more), but now I'm back and can continue development.Here are screens of KDevelop DVCS branching and committing managers. They can work with any DVCS (currently I support only Git code, but will give a love to Mercurial and Bazaar).Commit manager is a big “quick and dirty”, but I will try to make it clear tomorrow.

I've finished Bazaar and Mercurial basic support in KDevelop. Writing Bazaar plugin was very painful: still don't know why KDevelop wasn't able to load it (diff shows nothing interesting).The code is already in the KDE's svn repository :) But to get KDevplatform you can use my git repo ;)
