Software for scientific use (and exercises conducted): an interesting site

After talking to QtOctave, graphical front-end for GNU Octave, and gnuplot, explaining in detail how to compile with a click, the latest version from CVS, I got to meet a very useful website, called extrabyte.info, which collects, plus tricks to Gnuplot, advice on other software for scientific use compatible with various operating systems, A this address.
Also, for those who are struggling with the last efforts before maturity, or struggling with Analysis 1 the 2, on the same site you can find a number of exercises done, gradually growing (limits, study of functions and so on)… who has never gone to a limit that just would not be a function or abstruse? 🙂
