Dr. Rolf Freitags Projects


Priority notice
Most of the software i made was developed under Linux, but most of it, including the drivers, can be compiled and used with no or minor modifications under MS-Windows via Cygwin.


dupmerge - A Program for securely finding and optional linking/deleting duplicate files here.
Similar programs are
clink,
dmerge,
duff,
Duplicate Files Finder - Seems to be similar to dupmerge but with C++ source and a GUI,
Dupseek,
epac,
fdf,
fdfind,
fdupe,
fdupes,
find_duplicates,
freedup,
freedups,
fslint,
ftwin,
highLnk,
libpuzzle,
WeedIt,
and whatpix.

Compiler-Tests0 - A minimal compiler test suit, espacially for mikrocontroller compiler here.


randomize - An IPv4 number randomizer here.


Public Key Steganography here.


A driver for the cheap digital multimeter VC 840/VC 820 here.


A driver for the cheap digital LCR meter LCR 612 here.


A driver and powerbox for the cheap relay card 8fa for switching up to eight times 250 V AC / 5 A here.


Frequency and impulse counter program which needs only the parallel port IRQ for frequencies up to 270 kHz here.
The program runs under Linux with the hard realtime patch RTAI.


Some simple programs for the parallel port, e. g. a test to see if the data port is bidirectional and a simulator which simulates heartbeats and treads for an ergometer here.


A driver for reading/writing data on MMC/SD cards with an MSP430 microcontroller here.


A PCI template driver for linux with an interrupt handler for Kernel version >= 2.5 here.


A driver for the real time clock DS1339 and some driver stubs for the ARM9 platform here.


Apache2 and proftpd server configuration files with bandwidth and connection limitation for a server with a DSL connection here.


My Geiger counter page here.


My PC battery charging page here.


My physical curios pages: Diffusion Machine.


My Science Myths page.


USB-Sticks.64 GB USB memory stick

Other old projects, e. g. a random number test suit with an entropy test, coupon collectors test etc., are here.
