Intellectual property is an oxymoron.
Free software with C source code (GNU General Public License):
Zip files for Linux/Windows, tar.gz files for Linux only.

Support will be provided for Linux versions only. If you have problems running any of this software in Windows, my advice is to get rid of the buggy, crash-prone, virus magnet that you think is an operating system, and switch to a stable, secure operating system such as Linux.
There are only two types of people who use Windows:
1) Those who have no choice
2) Idiots
Those in the first category are invariably put there by those in the second category. See the quote above regarding Dilbert.

All free software is provided with indemnification equal to that provided by Microsoft (details here).

I once had software (some of it written by me) that used Linux to simulate MSDOS running a program that simulated a Z80 microprocessor running CP/M which in turn ran a program that simulated an Intel 8051 microprocessor running a program written in 8051 assembly language.

I thought it was funny as hell.

Proving that something is mathematically possible doesn't mean it will be useful. I once wrote a file compression program that achieved 100% compression regardless of the file being compressed. It worked every time. I named the program "delete".

If you're viewing this web page with Internet Explorer, please upgrade to Firefox.

Say goodby to spyware, popups,and malware.
Getting on the internet with Internet Explorer is like walking through a bad part of town at midnight with $100 bills hanging out of your pockets while shouting "I'm drunk!" It's just asking for trouble.

Caveat: If you have any problem at all with Firefox, don't bother trying to report the problem to them directly. Their website for reporting problems asks you to type in a number it displays to verify that you're human and not a spam-bot. Problem is that it claims you typed it incorrectly no matter what you input. This is either incredible incompetence or a deliberate rejection of any and all trouble reports. They don't want to hear about it. Nevertheless, Firefox is still the best web browser available (and it's free).

Software Indemnification: If users of any of my free software are sued for IP infringement, I will provide indemnification equal to that provided by Microsoft: I will cheerfully refund the full purchase price of said free software.
