Programmers Stack Exchange is a question and answer site for professional programmers interested in conceptual questions about software development. It's 100% free, no registration required.

Lately I have been learning of more and more programmers who think that if they were working alone, they would be faster and would deliver more quality. Usually that feeling is attached to a feeling that they do the best programming in their team and at the end of the day the idea is quite plausible. If they ARE doing the best programming, and worked alone (and more maybe) the final result would be a better piece of software.

I know this idea would only work if you were passionate enough to work 24/7, on a deadline, with great discipline.

So after considering the idea and trying to learn a little more, I wonder if there are famous one-man-army programmers that have delivered any (useful) software in the past?

Net productivity drops when hours go to high. Don't assume the best of the best are there merely because they invest more time. If that were the case, anyone could become a great programmer. –  Brian Feb 9 '09 at 20:31

Most of the answers are wrong. Anders didn't build C# or Turbo Pascal all by himself, for example. –  Robert S. Feb 10 '09 at 2:01

Its weird that the number of votes to close is constant, while this question have 22 up votes and 14 favs, it only needs 4 votes to have it closed huh? –  DFectuoso Feb 10 '09 at 17:21

  • Mike Pall: singlehandedly wrote LuaJIT, which is arguably the fastest dynamic language VM ever created.
  • Fabrice Bellard: created ffmpeg, qemu, TCC, and on the side also discovered the fastest known algorithm for calculating the nth digit of pi.
  • Julian Seward: created bzip2 and Valgrind.

Some personal favorites

Avery Lee of Virtualdub - Not really widespread use but the amount of code is impressive, not to mention he seems to have an obsession in assembly optimizing everything.

Gabest of Media Player Classic - As far as lines of code and impact, I think he deserves some appreciation for its early development.

I would posit that most really cool software came from one person. We could just as well ask "Does anyone know of any brilliantly designed software out there that is the result of a committee rather than a single individual?"
