http://vss.73rus.com/blog The latest entries of Vlad Skvortsov's Blog I spent quite some time trying to debug a simple shell script which used a function modifying global variables. The problem turned out to be a different behaviour of a shell function when that's called from a pipeline. ]]> http://vss.73rus.com/blog/2008/09/23/bourne-shell-functions-in-pipelines http://vss.73rus.com/blog/2008/09/23/bourne-shell-functions-in-pipelines I guess it's fairly obvious to statistics gurus, but I've spent quite some time trying to figure out how to fit a quadratic model (with linear coefficients) in R. Here's how. ]]> http://vss.73rus.com/blog/2008/07/14/fitting-quadratic-models-in-r http://vss.73rus.com/blog/2008/07/14/fitting-quadratic-models-in-r I've just released WadcomBlog 0.3. The major change in this version is getting rid of a notion of category (which you might have already noticed by looking at my blog). ]]> http://vss.73rus.com/blog/2008/07/05/wadcomblog-0.3-released http://vss.73rus.com/blog/2008/07/05/wadcomblog-0.3-released I've finally got around to release WadcomBlog version 0.2, with help from Oley in testing. Most important changes include tag cloud support and many more customizable settings.

Since it took me some time (and trial and error), I'm jotting down the recipe. ]]> http://vss.73rus.com/blog/2008/02/03/installing-russian-latex-on-macos-x http://vss.73rus.com/blog/2008/02/03/installing-russian-latex-on-macos-x Some time ago I've started taking notes of things that I would implement in a "perfect" programming language if I was creating one. I'm starting with minor and/or vague general things which I'm pretty positive about.

Hey, dudes, please make the check payable to my name! :-) ]]> http://vss.73rus.com/blog/2007/10/30/ditrack-is-worth-a-million-bucks http://vss.73rus.com/blog/2007/10/30/ditrack-is-worth-a-million-bucks I was long looking for a quick way to resize images (without loading them into iPhoto or what not). After digging into Jason Molenda's Makethumbs I've finally found one. ]]> http://vss.73rus.com/blog/2007/08/03/command-line-image-resizing-on-mac http://vss.73rus.com/blog/2007/08/03/command-line-image-resizing-on-mac I've been playing guitar for quite some time (though still at pretty amateurish level) and recently started recording some stuff. Here are two pieces that I think are the best of what I've done so far. ]]> http://vss.73rus.com/blog/2007/08/01/home-made-music http://vss.73rus.com/blog/2007/08/01/home-made-music I've been using the R Project to perform statistic-related tasks in my ongoing Ph.D work. It's a great system and the only thing I had missed so far was the ability to annotate plots with russian texts in cyrillic. Of course R is capable of that, but I haven't seen complete recipes on how to do it anywhere on the web. ]]> http://vss.73rus.com/blog/2007/05/20/cyrillic-fonts-in-R-plots http://vss.73rus.com/blog/2007/05/20/cyrillic-fonts-in-R-plots
