What single project requires more than 5-10 programmers?

Places with 1,000 developers spread throughout are working on hundreds of interacting projects. But, the communication and coordination isn't between all 1,000 developers.

Your last line: "But, the communication and coordination isn't between all 1,000 developers." Deserves more than one upvote - in any successful large scale project, the programmers work in very small groups, often just pairs, and interact with other groups mainly through the code-base itself. I am tempted to say almost exclusively through the code. That is why open source works as well as it does; if management actually added much value, linux could not be as useful as it is. In fact, I suspect management often is a negative factor; when large commercial projects work it is the result of superior design, and their ability to maintain adherence to the design, which is when management does add value.

If you're talking about "one product" which you want to sell, then build Windows or Microsoft Office with 5 programmers.

No, it's worse. Teams usually don't know what the others are doing, leading to broken, blocked or half-baked features and work duplication.

Here's an example: http://moishelettvin.blogspot.com/2006/11/windows-shutdown-c...

Having all those 1000 developers talk to one another would solve all problems, but this is a problem of scale which processes solve to a certain extent. Your opinion also highlights what's wrong with software development as a whole -- you seem to be under the impression that you can go and hack stuff in a vacuum, without interacting with others.

They don't all work on the same part of the kernel.

Sorry, but that's one of the stupidest arguments I ever heard (not referring only to you, but also to the parent's parent that brought it up).

Linux is a monolithic kernel, and because kernel parts depend on one another, unfinished changes are often blocking other changes and/or are breaking other parts.

Of course you aren't going to have 1000 developers working on the same line in the same file.

Linux is a product by itself, not a distribution of independent parts. You either have the whole kernel, or you have nothing. And I would die to see another kernel developed by 5 people, achieving the same feature-parity / stability and all that jazz as Linux.

It is GNU/Linux thank you.

Distributions are GNU/Linux. The Linux kernel is Linux.

And yes, I did well actually you.
