There is no official FindGSL.cmake module in the cmake distribution to “automagically” find the Gnu Scientific Library on Windows, Linux and Mac OS X. I have written such a module which works for my configurations, but might not cover all GSL installation on all OS. But you can modify it to fit your needs.

Sometimes one wants to download a source package or similar from sourceforge with curl and not with the browser, e.g. in a script where one wants to download a package automatically. It turns out, that due the latest changes in the download system of sourceforge this is not straightforward.
SciTE is a great text editor – in fact I tested a lot of text editors on Linux, Windows and Mac OS X, but always come back to SciTE since it is comfortable but still fast and small. Everytime I install SciTE on a machine I change the settings so that they fit my need. [...]
In order to prepare Linux executables for distribution, it’s a good idea to compile the executable in an old Linux distribution. Thus it depends only on “old” versions of libraries and the executable should work on most distributions out there (which provide newer but backward compatible libraries). E.g. Dialogblocks, a RAD for wxWidgets, is built [...]
The most frequented blog entries here are about installing Gnuplot on Ubuntu Linux or Mac OS X. These entries are still valid for the newer Ubuntu versions. But Gnuplot newest version 4.4.0 was already released, and in this release there are cairo based pdf and png terminals provided. So you don’t need the pdflib anymore. [...]
In research sometimes you want to make a movie from single images, like plots from experimental data or from calculation to visualize changes or so on. In order to achieve this you can use ffmpeg. First you have to create the images and save them, where the images need to have a continuous number in [...]
If you have your own Ubuntu server running you may encounter the maximal file size upload limit in php scripts which is set to 2Mb as default. In order to change that we first have a look what the size actually is. In /var/www (standard www directory) create a file called info.php with the following [...]
There is a new beta version of VirtualBox for Mac OS X available and installing Ubuntu Gutsy Gibbon worked like a charm (in opposition to Parallels). The only problem I encountered was, that it was not possible to mount a directory from the Mac OS X host in the guest system with either the internal [...]
I again have updated these instructions for Gnuplot 4.4.0 RC1 and newer Ubuntu versions. Find them in this post. Some months ago I wrote a small Howto about installing Gnuplot on Ubuntu Feisty Fawn with readline, pdf and wxWidgets terminal support. It turned out, that this howto was of interest for many people, since this [...]
I use an Ubuntu server as a work-horse for my calculations and connect from my desktop-pc with ssh to the server. For some applications (gnuplot =) this is really slow altough it’s over LAN. I found on the internet some instructions to improve this situation: instead of the AES cipher the arcfour and blowfish ciphers [...]
