Apart from what I do day to day in my job, I enjoyed making this little fella a few years ago.. around 3m downloads :)

Steviedisco 3D Chess - takes you to a google search for it

(I had a website for it, but I've let it lapse)

Bennu, an XBox live indie game.

Favorite? I was the lead programmer (and for a good portion, the only) for this project.

I'm probably making myself look horrible by saying this, but I really enjoyed making my 4 Elements 3 contest entry. It looked pretty much the same as the 4 Elements II entry that I did, but the code was (at the time) a lot cleaner. That, and it felt cool to have actually released something into the wild. Unfortunately the input code doesn't like newer machines, as something is horribly borked.

I really should get off my duff and make something cool one of these days.

LucidChart (see sig) is probably the best HTML5 app yet written--not that I'm biased or anything.

I suppose the thing I'm most proud of now is MyDinos, a browser based MMO I was technical lead on.

The thing I was most proud of at the time, was a proper s-buffer implementation when I was about 14, that was much faster than using a Z-buffer, back before 3D cards came along.

Go back around 14 years... I was 16, had an Atari STe and was trying to get a 50khz MOD reply routine to inter-op with STOS basic... it took two days of around 16h each but finally I got it working...

Best programming feeling ever and 14 years on I'm stil chasing something which can match it [sad]

That's amazing!

That is also amazing!!!!

Reverse engineering the hardware level interface of the R300 (Radeon 9700) family of GPUs and using that to start the development of the Mesa open source OpenGL driver for those GPUs. Also, the creation of Piglit, which is now used as the main regression testing suite for open source 3d driver development.

I wrote a very flexible and somewhat high performance ILP solver in C# over the course of about a week, back in C# 2.0-era, to learn the language. It's my favorite because I've used it in many, many other projects. It has turned into a real work horse for me, and over the years I've improved it greatly and made it more efficient.

It is pretty much the go-to tool for about 70-80% of problems that I look at and say to myself "uhg, I really don't want to have to write a solution for this right now. If only there was an easy way that wasn't horribly inefficient". I've used it as the back end for everything from compiler optimization problems, to AI in my game projects, to data number crunching. All sorts of optimization problems, really.

That is very cool. Did you implement any cutting plane techniques or just basic branch and bound?
