While the kernel 2.6.23 development cycle has not yet run its course, things are getting close enough to the end that it makes sense to start looking at the overall statistics for this release. As of this writing (shortly after 2.6.23-rc6 came out), just over 6,200 non-merge changesets had been added to the mainline kernel repository. These changesets came from 854 developers - a slightly smaller number than we saw for 2.6.22. Just over 350 of those developers contributed one single changeset. On a related note, LWN.net has a number of reports from the Linux Kernel Developer's Summit.

Linux users want two things for their hardware: drivers; and easy access to those drivers. The first is finally happening; and now, thanks to a Dell Linux project called DKMS (Dynamic Kernel Module Support), the other is on its way. Dell and Linux distributors have been working on DKMS for about five years now. Its purpose is to create a framework where kernel-dependent module source can reside, so that it is very easy to rebuild modules. In turn, this enables Linux distributors and driver developers to create driver drops without having to wait for new kernel releases. For users, all this makes it easier to get up-to-the-minute drivers without hand compiling device drivers.

"It's over. The magic is gone. The dream is dead. The egg has fallen off the wall and no amount of 'sudo' super glue can put his pieces back together again. I'm referring, of course, to the not-so-recent departure of Con Kolivas from the Linux kernel development community. Con - that champion of all things desktop centric - hung-up his keyboard this summer, the victim of an ideological rift within the Linux community." Update: And the first rebuttal appeared.

According to this KernelTrap article, the 0.11 Linux kernel was released on December 8th, 1991. Among the 'features' advertised in that release, Linus noted that the console was now capable of producing beeps, Linux gained native mkfs, fsck and fdisk utilities, and the com ports finally had adjustable line speeds. However, if you managed to get Linux booted you were immediately dropped into a root bash shell as Linux lacked a login system. It also lacked support for SCSI devices, and support for swapping to disk meaning it required at least 4MB of RAM to be useful.

It is not too surprising that Ubuntu came in first in DesktopLinux.com's 2007 Desktop Linux Market Survey, or that Firefox was the topmost browser by far. More interesting is that for the first time ever in the site's annual surveys, GNOME surpassed KDE among desktop environments (45% over 35%), with Xfce a solid third (8%).

"The development of the kernel has changed, and Linux is just getting better and better. However, with a community as large and fractured as the Linux community, it can sometimes be hard to get a big picture overview of where Linux is going: what's happening with kernel version 2.6? Will there be a version 3.0? What has Linus been up to lately? What does he get up to in his spare time? I had the opportunity to chat with the original creator of the Linux kernel, Linus Torvalds, in a number of email exchanges."

"Deciding whether a particular computer is a good candidate for installing GNU/Linux can involve a nightmare of details about hardware compatibility. Nor is assembling a custom computer on which to run GNU/Linux any easier. In both cases, you need to evaluate video cards, sound cards, printers, scanners, digital camera, wireless cards, and mobile devices for compatibility with the operating system. Fortunately, help is available."

"Dell's chief technology officer sees a huge future in Linux virtualisation for the once-dominant PC manufacturer. Kevin Kettler told an audience at LinuxWorld that virtualisation and Linux was no longer such an odd combination. "The two play to one another very strongly, particularly in the re-emerging trend of virtualisation," Kettler said."

"Linus Torvalds was only 22 when he decided in 1991 to share with friends and colleagues the code of Linux, the new OS he had created. The computer science student at the University of Helsinki could not imagine the revolution his decision would cause through the IT industry in the years to come. In this interview, he talks about why he released the code, offers his views on Microsoft and says the future belongs to open source."

"Don't expect to see key features of OpenSolaris showing up in the Linux kernel," said a top Linux maintainer. At his LinuxWorld opening keynote, Andrew Morton made it very clear that the appointment of former OSDL CTO and Debian co-founder Ian Murdock to Sun's OS platforms organization will not translate into a merging between the open source version of Solaris Unix with Linux. He didn't mince words. "It’s a great shame that OpenSolaris still exists. They should have killed it," said Morton, addressing one attendee's question about the possibility of Solaris' most notable features being integrated into the kernel. "It's a disappointment and a mistake by Sun." Morton said none of those features - Zones, ZFS, DTrace - will end up in the Linux kernel because Sun refuses to adopt the GPL.

"It has been almost two years since LWN covered the swap prefetch patch. This work, done by Con Kolivas, is based on the idea that if a system is idle, and it has pushed user data out to swap, perhaps it should spend a little time speculatively fetching that swapped data back into any free memory that might be sitting around. Then, when some application wants that memory in the future, it will already be available and the time-consuming process of fetching it from disk can be avoided. There is a vocal set of users out there who will attest that swap prefetch has made their systems work better. Even so, the swap prefetch patch has languished in the -mm tree for almost all of those two years with no path to the mainline in sight. Con has given up on the patch (and on kernel development in general). It is an unfortunate thing when a talented and well-meaning developer runs afoul of the kernel development process and walks away. So it is worth the trouble to try to understand what went wrong."

Continuing their historical series looking at the early Linux kernels, KernelTrap is discussing the 0.02 and 0.03 kernels released in late 1991. Though the actual source code has been lost to time, the article offers an interesting collection of emails by Linux creator Linus Torvalds about his new operating system, 'for hackers by a hacker.' Version 0.02 was the first usable release, gaining the ability to run programs such as gcc if compiled on Minix. Version 0.03 fixed buffer-cache issues that made it possible to compile gcc from Linux. Interestingly enough, at this point Linus thought of Linux as a short-lived project saying, "wait for Hurd if you want something real. It's fun hacking it, though (but I'm biased)."

"Development of OpenHAL, a wireless network component for Linux, can now resume unfettered after months of legal uncertainty. OpenHAL allows people with wireless cards based on technology from Atheros Communications, Inc. to connect to networks using solely free and open source software. Earlier this year, allegations were made that OpenHAL might include material that infringed the copyright of Atheros' proprietary HAL software. The Linux Wireless developers asked the Software Freedom Law Center to investigate these rumors, and SFLC agreed to help on a pro-bono basis."

"People who think SD was 'perfect' were simply ignoring reality," Linus Torvalds began in a succinct explanation as to why he chose the CFS scheduler written by Ingo Molnar instead of the SD scheduler written by Con Kolivas. He continued, "sadly, that seemed to include Con too, which was one of the main reasons that I never the notion of merging SD for very long at all: Con ended up arguing against people who reported problems, rather than trying to work with them." He went on to stress the importance of working toward a solution that is good for everyone, "that was where the SD patches fell down. They didn't have a maintainer that I could trust to actually care about any other issues than his own." Update: OSNews user superstoned pointed us to the other side of the story.
