Moving to ArchLinux
Everything should be made as simple as possible, but not simpler. A. Einstein Last week I decided to move to ArchLinux. I wasn’t excited at all with the release of Oneiric, as it was all about unity, and nothing more. The ubuntu button moved inside the dock, not in the top level bar, etc. I upgraded from Natty and everything went flawless as usual.

Still, it is more network oriented, and I wanted something more general. I also thought of Lisp and Scheme.

Pure procedures in Fortran
In Fortran, a keyword I haven’t used enough so far is PURE. We want functions but also many subroutines to avoid side-effects. To ensure this, Fortran let us add the keyword PURE in front of a procedure declaration in order to tell the compiler that it does not contain any side-effect.

I got this proverb from an italian friend who was quoting his grandmother. This means litterally “who spends more, spends less”. I’ve been thinking about it for some time. First, this was the argument that made me go for my new Bose bluetooth headset, which is quite expensive. I bought a Bose Mini Soundlink some months ago and I am completely happy with it. It was also not cheap, but, the counterparts:
