"Sometimes I'm tardy and miss things for weeks and need prodding, and sometimes I pull almost before you've sent the'please pull' message. I'm unpredictable. Or keeping you on your toes. Or incompetent. Pick whatever suits your mood ;)"— Linus Torvalds in anOctober 17, 2007 message to the Linux Kernel Mailing List.

As GNU/Linux becomes more popular, the motives behind its inceptions are often forgotten. Linux is a free operating system, but its broadening userbase perceives this freedom as pertaining to cost, not rights and liberty.

GnuTLS, which released version 2.0.2 last week, removed the TLS Authorization capability, due in part to an effort to circumvent the IETF standardization process.

To a business user of Linux, the development of its kernel may appear so Byzantine, with dozens of people maintaining different pieces and hundreds more volunteers submitting code, that it's hard to see where new features are headed.

What's Linux worth? The question has been a favorite of technology groups and cocktail party conversations ever since a character named Jeff V. Merkey offered $50,000 for a copy of Linux. The offer was a ploy. Merkey wanted it under the BSD license, which would have undermined the terms of the GPL. So he didn't get it. But we know, at least, that $50,000 proved to be a low bid.

Jeff Garzik posted a series of nine patchs to the lkml titled to "remove [the] 'irq' argument from all irq handlers", explaining, "the overwhelming majority of drivers do not ever bother with the 'irq' argument that is passed to each driver's irq handler. Of the minority of drivers that do use the arg, the majority of those have the irq number stored in their private-info structure somewhere." He noted that he had no intention to push the patches upstream anytime soon.

While Linux desktop surveys are nothing new, no recent polls have looked specifically at Linux graphics when it comes to X.Org video drivers, hardware, and related video features. We, however, at Phoronix see a need for this information to be profiled and have launched the first-annual Linux graphics survey. This survey is intended to allow the development community to get a better understanding of the video hardware in use, what open-source and closed-source drivers are being used, and other relevant information.

When asked how to best refer to kernels between official releases and release candidates, Linus Torvalds pointed to his automated git snapshots. "I still call them 'nightly snapshots', but they do in fact happen twice a day if there have been changes, so that's not technically correct," he noted. The latest snapshot is 2.6.23-git15, "this is an exact name, because you can go to kernel.org and look up the exact commit ID that was used to generate it (there's an 'ID' file associated with each snapshot there)."

Richard Stallman, in receiving an honorary Doctorate from Italy's University of Pavia, brought back memories of the basic primary school principle that students bringing cookies to class should bring enough for everyone.

LXer Feature: 21-Oct-2007

Some of the big stories this week include Linux vs. Windows Power Usage, Microsoft gets two licences approved by the OSI, Kevin Carmony switches to Ubuntu and on top of all that we have a slew of LXer features including a couple of reports from T-DOSE, Carla Schroder continues her series on Digital Photography and a reader submitted article with some advice for those trying to decide between Windows or Linux.

This tutorial shows how to set up a Ubuntu Gutsy Gibbon (Ubuntu 7.10) based server that offers all services needed by ISPs and hosters: Apache web server (SSL-capable), Postfix mail server with SMTP-AUTH and TLS, BIND DNS server, Proftpd FTP server, MySQL server, Courier POP3/IMAP, Quota, Firewall, etc. This tutorial is written for the 32-bit version of Ubuntu Gutsy Gibbon, but should apply to the 64-bit version with very little modifications as well.

About two months ago, I switched from OS X to a new Dell with Ubuntu Linux at work. For the most part, I could not be happier, but there are a few things I really miss about my Mac. Here is a list of the 10 things I miss the most.

It was an exciting day for me today. I had done my research and I was ready to perform the upgrade to Ubuntu 7.10! This was my story.... M Perks ReviewLinux.Com

"Currently in mainline the balancing of multiple RT threads is quite broken. That is to say that a high priority thread that is scheduled on a CPU with a higher priority thread, may need to unnecessarily wait while it can easily run on another CPU that's running a lower priority thread," began Steven Rostedt, describing his patchset to introduce improved real time task balancing.

In a brief follow up to the earlier pluggable security discussion, Thomas Fricaccia reflected on the implications for the various security frameworks, "I noticed James Morris' proposal to eliminate the LSM in favor of ordaining SELinux as THE security framework forever and amen, followed by the definitive decision by Linus that LSM would remain."

Evgeniy Polyakov announced a new version of his distributed storage subsystem, "this release includes [a] mirroring algorithm extension, which allows [the subsystem] to store [the] 'age' of the given node on the underlying media." He went on to explain why this was useful:..

The previous 2.4 Linux kernel maintainer, Marcelo Tossati, resurrected a discussion on adding support for out of memory notifications to the Linux kernel. He explained, "AIX contains the SIGDANGER signal to notify applications to free up some unused cached memory," then noting, "there have been a few discussions on implementing such an idea on Linux, but nothing concrete has been achieved." In a request for discussion, Marcelo added, "on the kernel side Rik suggested two notification points: 'about to swap' (for desktop scenarios) and 'about to OOM' (for embedded-like scenarios)."

Ken Chen submitted a patch to reduce the memory footprint of schedstat in a thread titled, "schedstat needs a diet". He explained, "schedstat is useful in investigating CPU scheduler behavior. Ideally, I think it is beneficial to have it on all the time. However, the cost of turning it on in production system is quite high, largely due to number of events it collects and also due to its large memory footprint." His patch converted numerous unsigned long variables to unsigned int, "most of the fields probably don't need to be [a] full 64-bits on 64-bit [architectures]. Rolling over 4 billion events will most likly take a long time and user space tools can be made to accommodate that."

"This is a request to merge KGDB into the mainline kernel," Jason Wessel announced, posting a series of patches aiming toward that goal. He continued, "as of right now KGDB is comprised of 21 different patches adding in the core api and docs first and then working up to add drivers and arch specific support to KGDB. The patches were broken down into logical pieces for review and comments."

"I'm trying to keep some external drivers up to date with the kernel, and the first two weeks after the release is the worst time for me. There is no way to distinguish the current git kernel from the latest release. It's only after rc1 is released that I can use the preprocessor to check LINUX_VERSION_CODE," explained Pavel Roskin, describing the ongoing effort to keep the out of tree MadWifi driver in sync with the latest released kernel.
