technically... A few games I wrote in High School (79-83) on the Commodore PET are out there on sites to download and play... http://www.mobygames.com/game/toss http://www.mobygames.com/game/pet/tic-tac-toe_ http://www.mobygames.com/game/pet/tron-light-cycle-game http://www.mobygames.com/game/pet/tron-journey-to-the-mcp

My VIC-20 and Commodore 64 versions were better, but those came later

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…

Is that code?

The Google link? It's a nonsense query that I figured would have no results (better read it quick, before Google indexes this page ;-)), which is the only way (outside Google) to show off the no-results page.

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.

This is an extremely self contained program, doing a particular set of things over and over in an isolated environment, with about four or five users, and "bugs" are generously defined as "bugs reported to me."

People still play the Warcraft III map I made in 2006, mostly in Russia. It relied heavily on an extension of the scripting language called vJass created by a genius eastern european hacker named Vexorian and was one of the most advanced of its type for a while. It was also ported to the DotA 2 engine, where it has millions (!) of subscribers.

Which map if you don't mind? Curious if it's one of those I played with my friends in high school.

1994. VB6/SQL, although it started as FoxPro and VB6/SQL was introduced in 1995 or 1996. WRAP accounting software for a financial company that was sold around 2003. Not much in use now, but I hear they still have a few clients and a small 2-3 person support team.

2000. VB6. Manufacturing workflow / management system, BOM..... I did some consulting work at the same company a year ago and that system was still chugging along. They had pretty much rewritten / replaced everything else around the place but apparently didn't see a need to change my module. I was amused to have a couple of guys come and ask me questions/advice, and all I could do was sympathize.

2012 for me. Also VB6 though...

I was at a company from 2000-2003, and wrote a lot of its software. That company is still around, and they also licensed their software to a spinoff. I was brought in for some consulting to the spinoff and was equal parts pleased and horrified to see that some of my software was still in use and pretty much untouched. Horrified because back in 2002 I was already agitating that it was time for a rewrite for one part of it.

1998. Lotus Formula Language Runtime engine. Completely rewrote the original written by Ray Ozzie. GA released in 1999 in Lotus Notes/Domino R5.

The sad thing is, that vintage of lotus notes was actually tolerable, compared to what came later.

I feel like I have stockholm syndrome after using Notes from several years. I hated notes, but I really miss the 'Copy to New' function from creating new emails from already sent items.

Anyone know of a client that supports this other than Notes? (sorry for the hijack)
