I wrote a "single-use bookmarking" app, http://app.reminderbear.com/, during spring break of 2011 and haven't touched it since.

It was the first thing I wrote and I'm still insanely proud of it.

It's chugging along sending 5-6 reminder emails every day and I use it once a month or so.

I haven't dug around in the Miranda IM code in years, but I hope there is some of my code left, even if it's just 1 line, would have been written in 2000.

I do know there are plugins I wrote for ACDSee as a coop student in 2000. I can still see some of the icons I drew.

Roughly a decade. The VB6 program that I wrote to test a prototype of a measurement instrument, is still used in the factory, supporting manufacturing of the released product. It's a couple thousand lines, and nobody wants to touch it with a ten foot pole, but it also has no known bugs, and will live for the remaining lifetime of the product.

>no known bugs

I don't think I have ever heard that phrase. Every non-trivial piece of software I have ever worked on has a collection of bugs that just get carried forward indefinitely ie hard to fix, only affects a small number of people and there is an easy work around so just ignore it. The idea of having zero open bugs is... foreign.

In 2001, I wrote a tag balancer (for HTML input, it also did some rudimentary XSS filtering) in PHP and then translated it to Cold Fusion (I was applying for a CF job and figured it might be useful to actually learn it).

I believe that both variations are still running, the CF version on Metafilter, and the PHP version was used in B2, which became WordPress. A few years ago, I was asked by the WP team to relicense the code from GPLv2 to GPLv2+ and sure enough, it lives on with relatively few modifications in WordPress: https://github.com/WordPress/WordPress/blob/b1804afeaf07eb97...

Perhaps most notable, is that I wrote it w/o having taken a compilers class or having much (any) understanding of stack-based parsing, but it still lives on, so I guess it was good enough to get the job done.
