There is some of programs written by me and some current projects.

Programs for the HP48 graphic calculator are in its own section.
Abelhas ("bees" in Portuguese) is a Lua package for particle swarm optimization -- a straightforward optimization technique for discrete and linear functions. As a pure-Lua software, it will run in every system with a Lua interpreter.
Lua-eSpeak is a Lua binding to the eSpeak text-to-speech (TTS) library. It adds voice synthetisation features to the standard Lua interpreter. Works under Linux and Unix.
Lua-GD is a Lua binding to the GD image drawing library. It adds image authoring features to the standard Lua interpreter. Works under Linux, Unix and Windows.
PyPreTeX stands for a "Pythonic Previewer for LaTeX": a small Python/GTK+ application that displays images generated by the (La)TeX interpreter. It is a handy tool for testing LaTeX code and exporting equations for other applications. For Linux/Unix.
Lua-iconv is a Lua binding to the POSIX iconv library. The iconv library converts a sequence of characters from one codeset into a sequence of corresponding characters in another codeset.
A small library that provides the POSIX crypt() to the standard Lua interpreter. It's my first "real" Lua module ;)
A small command-line application that formats LISP code into HTML.
A PHP script that renders images from text using TrueType fonts. It allows some dynamic generation of artistic headings for webpages.
A nice and minimalistic CMS I wrote for handling my old homepage. It features some automation and allows uploading of local files to the web server. All data are stored in portable flat-files, so no database is needed.
An Lua script that converts ".sub" subtitle files into ".srt" ones.
An Lua script that changes the timing of ".sub" subtitle files. Useful for synchronization.
I really small application that converts text files in header files for use in C code; 100% pure ANSI C. Pick up, compile, and run.
An old Perl script for thumbnailing and indexing images in HTML files. It generates index files for all image files in a given directory. Runs under Unix systems and needs the ImageMagick.
A command-line application that generates C arrays with the contents of a given binary file. Useful for including binaries into applications. This package includes the C source code and some old Linux binaries. It can be compiled in any Unix system (and, maybe, Windows).
A Python script that reads vBulletin-based Web forums and outputs RSS data for use with any news aggregator. The script is utterly small and may be easily adapted.
A Perl script that reads phpBB2 bulletin boards and outputs RSS data for use with any news aggregator. The script is utterly small and may be easily adapted.
A Perl script that reads Phorum bulletin boards and outputs RSS data for use with any news aggregator. The script is utterly small and may be easily adapted.
An nice AutoLISP routine that draws integrated circuits with DIL encapsulation. You give some information about the circuit and it does the boring drawing work. For AutoCAD R14.
A nice Delphi program and the circuitry needed for building a single-channel digital oscilloscope. Utterly simple, but it was a nice learning time. WARNING: This is a old program that works under Windows 9x/ME only. I used direct hardware access functions that does not work on newer Windows releases. Feel free to fix this.
A nice Pascal-based RPN calculator, with scripts, aliases, etc. available for MS-DOS/Windows and Linux and written when I was learning Pascal.
A toy Pascal program for sending and receiving data from the parallel port in MS-DOS. Written when a was studying electronics.
A Pascal program and the circuitry needed to build a voltmeter on the parallel port. For MS-DOS.
