F:	ellipsis.c


N:	Fotomultiplier-Magnitude
L:	C

F:	fotomultiplier-magnitude.c


N:	NED-Phot

F:	NED-phot.pl 
F:	NED-ponfot.dat.gz


N:	Classif
L:	Perl

N:	Prugniel-Slicer
L:	Perl
U:	Organizes the data from Prugniel A&AS 1998, 128, 299-308. Astronomers...

F:	sinmax.c 
F:	sinmax.Makefile


N:	TransPolar
L:	C
U:	Makes an image transformation from cartesian to polar coordinates, i.e., from (x,y) to (rho,phi). Useful for making image Fourier transforms.

N:	Ascii2fits
L:	C
U:	Converts a text data file on a FITS image file. Maybe useful mostly for astronomers.

==Instrumentation/Interface==


N:	Motor-Passo
L:	C/Linux
U:	An evolution from led-menus. This one controls a stepper motor through the parallel port. Now in Linux. The stepper motor it is not included in the distribution.
F:	motor-passo.c 
F:	motor-passo.h 
F:	motor-passo.Makefile


N:	Led-Menus
L:	C/DOS
U:	It drives leds connected to the parallel port on and off on animated sequences.  You can make you computer control your christmas tree in a very akward way. Made to test parallel port control under DOS :(  
F:	led-menus.c


N:	Serial Read
L:	C
U:	Reads the serial port on Linux with both cannonical and non-cannonocal methods. It was written to interface a multimeter. Based on Serial Programming HOWTO

F:	FFerrari-ImobilDB.tgz


N:	Agenda
L:	Perl
U:	A simple shell address book, with names, addresses, etc. Simple and useful. It stores the data in a simple textfile. Exports in HTML. Also useful to learn some Perl tricks with FORMAT for example. Includes a X version with Perl/Tk.
F:	agenda_0.21.pl

L:	WinNT shell
U:	Utility script to change the network configuration on a Windowze system. It uses netsh utility that comes with Win 2000/XP to change the network config with a .bat file.
