Hey Hubski,
I made a black & white/color ascii picture converter in C# that should be able to compiled in mono without much of a struggle. I ran a couple of tests to compare outputs and for the most part I'm satisfied. I ended ditching the original function I had written to generate black and white (but it could print out to notepad which was kinda cool) due to a smushing bug; but it gave the black and white outputs a lot more character.
Do you have any simple programs you'd like to share?
When learning about Diffie Hellman at uni I wanted to get a feel for the process and how it could be used so I made this little Java program that basically hand-waves the actual server/client communication part away. So it uses the java.security and javax.crypto libraries and should generate valid certificates but I've never really revisited it to check it's all correct; I'm sure there's more to it than that but at the time it was really handy to have gone through that process.
Nice. How did you do the conversion table for gray scale -> characters? Did you find them somewhere or devise them yourself? Maybe consider using character literals instead of having to put them in comments e.g return '*'; else if (shade >= 210)
