How will you ever get the network effects needed to get sustained users with a commercial tool?
Given Git was created because BitKeeper, a commercial tool, pulled their permission for kernel developers to use their tool aren’t we ignoring a lesson there?
Literally true if it's that one guy you're talking about.
Also, you should hear Linus talk about building git himself, what he built wasn't what you know as git today. It didn't even have the commands like git pull, git commit etc until he handed development over.
Uhh, to be fair, if the goal was only to recreate git from 2005, it probably wouldn't cost $17M. I'd hazard a guess that they're recreating modern git and the emergent stuff like issues, PRs, projects, etc. I've also heard that the core devs for git are essentially paid a salary to maintain git.
I'd be 1,000x more interested in a project with the official git maintainers' buy-in to leverage the alleged power of LLM development to bring all git's features into libgit2 (or whatever, but that's a starting point) and switch git itself over to using that as its backend.
I've twice in my career found reasons that git being (officially; I have no interest in dealing with another implementation with its own missing features and distinct bugs) a library instead of a messy ball of scripts and disparate binaries, would have saved me tons and tons of time. You can look at the stories of how Github was designed and built, or look at the architectures of other similar software, and see folks struggling with the same issue. You'll run into frustration on this front pretty much instantly if you try to build tooling around Git, which turns out to be such a useful thing to do that I've ended up doing it twice in ~15 years without particularly looking for reasons to.
(While we're at it, how about some kind of an officially-blessed lib-rsync with a really pleasant API?)
Thinking it for bit it comes to "what comes after Git" and what does "Git" mean there.
To build better tool than git, probably a few months by tiny team of good developers. Just thinking of problem and making what is needed... So either free time or few hundred thousand at max.
On other hand to replace GitHub. Endless millions will be spend... For some sort of probable gains? It might even make money in long run... But goal is probably to flip it.
No he didn’t. He built a proof of concept demo in 7 days then handed it off to other maintainers to code for real. I’m not sure why this myth keeps getting repeated. Linus himself clarifies this in every interview about git.
His main contributions were his ideas.
1) The distributed model, that doesn’t need to dial the internet.
2) The core data structures. For instance, how git stores snapshots for files changes in a commit. Other tools used diff approaches which made rewinding, branch switching, and diffing super slow.
Those two ideas are important and influenced git deeply, but he didn’t code the thing, and definitely not in 7 days!
Those were not his ideas. Before Git, the Linux kernel team was using BitKeeper for DVCS (and other DVCS implementations like Perforce existed as well). Git was created as a BitKeeper replacement after a fight erupted between Andrew Tridgell (who was accused of trying to reverse engineer BitKeeper in violation of its license) and Larry McVoy (the author of BitKeeper).
I agree and that’s the point I was trying to make.
Linus’s contribution is a great one. He learned from prior tools and contributions, made a lot of smart technical decisions, got stuff moving with a prototype, then displayed good technical leadership by handing it off to a dedicated development team.
That’s such a good lesson for all of us devs.
So why the urge to lie and pretend he coded it in a week with no help? I know you’re not saying this, but this is the common myth.
He did what needed to be done. Linux similarly has thousands of contributors and Linus's personal "code contribution" is almost negligible these days. But code doesn't matter. Literally anyone can generate thousands of lines of code that will flip bits all day long. What matters is some combination of the following: a vision, respect from peers earned with technical brilliance, audaciousness, tenacity, energy, dedication etc. This is what makes Linus special. Not his ability to bash on a keyboard all day long.
The parent comments are arguing that 17million for git 2.0 is insane because Linux wrote the original in a week.
Except that’s not true. He sketched out a proof of concept in a week. Then handed it off to a team of maintainers who worked on it for the next two decades.
It’s also not pedantic because Linus himself makes this distinction. He doesn’t say he coded Git and specifically corrects people in interviews when they this.
