Sadly, the educational applications for Apple IIs I wrote in the mid 80's are no longer in use.
Also between 1999 and 2001, I was involved in the LiViD project where I worked on a port to PowerPC. I don't recall any patches actually landing into LiViD because it turned out that the bug was in GCC itself, a bug I was told must have existed since the mid-eighties. I didn't directly write the GCC patch, but did debug the compiler error and worked with the GCC team on the fix. This directly resulted in a port of Xine to PowerPC. (LiViD and Xine are early projects for multimedia and DVD playback on Linux) Xine exists today, but it's unlikely any of my code is in it. While the GCC fix is not my code, the fix itself still endures and exists because of my interaction with the project.
It's a newer example, but code I wrote simply as a demo for the Cairo graphics project back in 2004 became integrated into Tuxpaint and is still used today for rasterizing SVG graphics into stamps.
One bit that I hope is gone is the ONC RPC stuff I wrote for talking to the credit card processing engine we were using back then. That was pretty ugly. It was my first programming job, I'd never done RPC before, and I hacked up something pretty kludgy to make it all work. Not my proudest moment. :-(
I started a Mac app in 1988; the same code base (with tons of people touching it since I last saw it in 1994) is still a real product for sale today. No idea why.
The smaller the userbase, the more likely the code is to remain in service forever. The oldest code I've written is http://www3.amherst.edu/~scrutiny/about.php , which has gotten a facelift since I wrote it in 2004, but otherwise seems to have the same functionality and code backing it. Pretty much everything professional is gone...hell, the only employer of mine that is still in business is Google. When I left them…
