I place here some work-related projects/texts. Some might find them useful. A better name for this stuff is probably pre-work.

At the moment all the programs posted are written in C++ and python, just by me (but the algorithms come from a variety of sources. by the way, when they start patenting numerical methods, I'll give up science).

I used maxima (with the wxmaxima interface) for symbolic computations; I've recently discovered sympy, and I love it.
I warmly recommend vim for any kind of editing.
I also recommend gnuplot, which I use daily in my work, and for most figures in my articles/reports.
Using gnuplot with Gnuplot.py is trivial and Python makes the whole process much more efficient.
I also use paraview and even blender for visualisation of data.
