Free Software Linux

"This time around, we have 60+% of the changes in drivers, notably drives/video and drivers/media, with some infiniband, networking and usb lovin' to fill things out," began Linux creator Linus Torvalds, announcing the 2.6.23-rc3 kernel. "The rest is (as usual) mostly arch updates," he continued, "this time mostly mips, m68k and uml." Linus noticed that Linux kernel development has been managed with git now as long as it was managed with BitKeeper, a little over three years for both tools. He explained, "the most striking difference has nothing to do with git or BK (the switch-over timing was just the reason I decided to take a look), but with the fact that we're not just continuing to develop, but we're developing faster and with more people," adding:

"So during the three years 2002->2005, we had 63,428 commits, attributed to 1,560 different authors (caveat: misspellings etc will mean that some people get counted more than once). During the last three years, we've had 96,885 attributed to 4,068 distinct authors (with the same caveat, obviously).

"I didn't do a lot of per-commit statistics yet, but from the little I've done it also seems like we've gotten increasingly better at doing small commits (which is probably one of the reasons we have a larger number of them, but also why we have more authors - small commits is how people get into doing kernel development)."
