SteamOs: the good, the bad, or the ugly?

You may have heard that Valve, one of the major videogames companies, is going to release its own operating system: SteamOs. It is based on Debian: basically, it's just a Debian GNU/Linux distro with GNOME, that comes with Steam preinstalled and ready for use. If you want to try it, I have prepared a VDI image for Virtualbox (you will need to create a Debian VM, with 3D enabled):

Kartesio: best fit curves with experimental points

I finally had the time to build a simple website for Kartesio. This is a program I wrote about two years ago for my phisycal chemistry laboratory: I needed to calculate best fit curves for some experimental points I got from the refractometer and the regression algorithms available in the common office suites were not so good. But I also wanted something really simple: why sould I use "R" if I just want to best fit some points? So I decided to create a program which does this operation and only this one, but does it well. Kartesio is able to best fit curves using a regression algorithm or a neural network.
