With Linux on the desktop going from a slow crawl to verging on an explosion, many have toiled with the question: How do we make this happen faster? A well-known Austin-based Linux Advocate thinks he has the answer.

"The Intel Open Source Technology Center is pleased to announce the release of version 0.1 of LatencyTOP, a tool for developers to visualize system latencies. Slow servers, skipping audio, jerky video - everyone knows the symptoms of latency. But to know what's really going on in the system, what's causing the latency, and how to fix it... Those are difficult questions without good answers right now. LatencyTOP is a Linux tool for software developers (both kernel and userspace), aimed at identifying where system latency occurs, and what kind of operation/action is causing the latency to happen. By identifying this, developers can then change the code to avoid the worst latency hiccups."

"Many office workers have the same morning routine: turn on the computer, then grab coffee, catch up with coworkers, or look at paperwork while Windows boots up. Others save time, but waste energy, by keeping their machines on all the time. Now Device VM, a startup based in Silicon Valley, has a product that circumvents the everlasting boot-up. The company has recently released a tiny piece of software that, when integrated with common computer hardware, gives users the option to boot either Windows or a faster, less-complex operating system called Splashtop."

"The Linux 2.6.23 kernel comes with a modular scheduler core and a Completely Fair Scheduler, which is implemented as a scheduling module. In this article, get acquainted with the major features of the CFS, see how it works, and look ahead to some of the expected changes for the 2.6.24 release."

Abdel Benamrouche announced that he has updated the original 0.01 Linux kernel to compile with GCC-4.x, allowing it to run on emulators such as QEMU and Bochs. After applying his series of small patches, Abdel explains that the 0.01 kernel can be built on a system running the 2.6 Linux kernel. He added that he's successfully ported bash-3.2, portions of coreutils-6.9, dietlibc-0.31 (instead of glibc), bin86-0.16.17, make-3.81, ncurses-2.0.7, and vim-7.1 all to run on his modified 0.01 kernel.

"If there is a defining feature in Apple's Leopard, it's Time Machine. As cool as it may be, the fact is that we, as Linux users, are obviously not going to see much benefit from this is pitiful. So it's a good thing that open source developers have taken it upon themselves to create something similar, be it not a 'pretty' alternative."

It seems that each distribution has found a niche: Red Hat and Ubuntu are the leaders in their markets, and SUSE is a comfortable runner-up. However, history has shown us that businesses are not content to stay still too long or play second fiddle. So, what will Red Hat, SUSE, and Ubuntu have to do in the new year to gain new ground?

"The year is winding down and while we have a lot to look forward to next year, what were the greatest Linux innovations of this year? This year at Phoronix, we have published over 325 articles, with most of them being Linux hardware and graphics reviews, and that is in addition to over 700 original news entries. After spending much time in considering what the "best" and most substantial Linux gains over the year have been, we have comprised a list of what we believe are the greatest Linux innovations of 2007 along with our reasoning behind these decisions."

"LinuxDevices.com is pleased to publish an overview and papers from the Ninth Real-Time Linux Workshop held in Linz, Austria, Nov. 2-3, 2007. The papers, available for free download without registration, span a broad range of topics, ranging from fundamental real-time technologies to applications, hardware, and tools. As usual, the conference was organized by the Real-Time Linux Foundation. This year, it was held at the Johannes Kepler University in Linz, Austria."

"gOS is made by Everex, a mid-range PC vendor. It's based on Ubuntu Linux 7.10 and runs the Enlightenment E17 interface instead of KDE or Gnome. Despite not being created by Google, the focus of gOS is Google's online applications such GMail, Google News, Google Maps, Google Calendar, YouTube, etc. It's a neat concept for a Linux distribution, but how practical is it? We'll find out in this review."

"This is the listing of the open bugs that are relatively new, around 2.6.22 and up. They are vaguely classified by specific area," Natalie Protasevich said, posting a current list of bugs each linking to an appropriate bugzilla.kernel.org entry. Andrew Morton reviewed the list, noting 'no response from developers' in response to many of the bugs. David Miller pointed out that in some cases this wasn't true, referring to 46 bug fixes queued in his networking tree and another 10 already pushed upstream, "when someone like me is bug fixing full time, I take massive offense to the impression you're trying to give especially when it's directed at the networking. So turn it down a notch Andrew." Andrew wasn't convinced, "first we need to work out whether we have a problem. If we do this, then we can then have a think about what to do about it. I tried to convince the 2006 KS attendees that we have a problem and I resoundingly failed. People seemed to think that we're doing OK."

"Faster than virtualization, but harder to implement, containers are a promising security technology for Linux. Watch the 2.6.24 kernel for experimental support for creating and managing containers."

The Completely Fair Scheduler was merged for the 2.6.23 kernel. One CFS feature which did not get in, though, was the group scheduling facility. Group scheduling makes the CFS fairness algorithm operate in a hierarchical fashion: processes are divided into groups, and, within each group, processes are scheduled fairly against one another. At the higher level, each group as a whole is given a fair share of the processor. The grouping of processes is done in user space in a highly flexible manner; the control groups (formerly 'process containers') mechanism allows a management daemon to classify processes according to almost any policy.

Turbolinux has followed Novell, Linspire, and Xandros in signing a patent and technology agreement with Microsoft. "In a deal that could lead to the creation of a unique cross-platform authentication system for heterogenous networks, Tokyo-based Linux distributor Turbolinux announced this morning, Japan time, it has reached an agreement with Microsoft for a cross-licensing of the two companies' patent portfolios."
