Interview With BitKeeper Author Larry McVoy

Jeremy Andrews writes "KernelTrap has spoken with Larry McVoy, BitMover founder and primary BitKeeper author. BitKeeper, a distributed source control system, has been adopted by Linux kernel creator Linus Torvalds and condemned by free software icon Richard Stallman. In this interview, Larry looks back through the years, describing his exposure to computers and Linux. He also discusses the history of BitKeeper, from writing NSElite for Sun (which turned into their still used SCM, Teamware), to his desire to keep Linus from burning out, to the present day solution. The choice to not license BitKeeper under the GPL is also explained. Larry discusses much beyond Bitkeeper as well, exploring some of his other interests. Find the full interview on KernelTrap."

RMS condemning non-free, not BitKeeper itself

[Seth Finkelstein]

Agree or disagree, I believe the phrase BitKeeper ... condemned by free software icon Richard Stallman mis-states the issue. It's not the merits of BitKeeper _per se_ which are at issue. Rather, it is the very idea of the use of it - even if it's technically better!

What RMS actually said was:

Bitkeeper issue
The use of Bitkeeper for the Linux sources has a grave effect on the free software community, because anyone who wants to closely track patches to Linux can only do it by installing that non-free program. There must be dozens or even hundreds of kernel hackers who have done this. Most of them are gradually convincing themselves that it is ok to use non-free software, in order to avoid a sense of cognitive dissonance about the presence of Bitkeeper on their machines. What can be done about this? ...

Linux, the kernel, is often thought of as the flagship of free software, yet its current version is partially non-free. How did this happen? This problem, like the decision to use Bitkeeper, reflects the attitude of the original developer of Linux, a person who thinks that "technically better" is more important than freedom.

Value your freedom, or you will lose it, teaches history. "Don't bother us with politics," respond those who don't want to learn.

That's a very profound statement. It's easy to sneer at it, to dismiss it ad hominem. But he raises important points which deserve to be addressed in depth.

Ah, there's the rub

[Nygard]

The system is no longer GNU + Linux kernel. If it's about giving credit in proportional amounts, then X, perl, Berkeley, Apache, Netscape, and many other major contributors should also be recognized.

I do understand that some of these can be stripped away without impairing the OS, but some of them cannot.

While calling the whole ball of wax "Linux" may be overstating the importance of the kernel, calling it GNU/Linux understates the importances of all the other contributions.

My only problem with it, is that if I am using it for free, I am _forced_ to upgrade when new versions become available.

So pay up and quit whining about it.

You're getting something for free, nothing, nada, zip that someone else has spent time and effort on, why are people not appreciative of this fact any more?

You don't go whinging about a free beer your mate gives you do you? And yes, even that beer will come with conditions (like you're supposed to drink it with him).
