"Last year's LinuxWorld Conference & Expo in New York was a time for major vendors like IBM and Hewlett-Packard Co. to debut new hardware offerings running various flavors of the Linux open-source operating system. This year, with Linux-based server sales holding their own, the focus is on keeping those customers happy by giving them the kind of service and support that until now has mainly gone to customers running Unix and Windows. The Linux community is also looking for ways to broaden use of the operating system in business computing. About 150 vendors are expected at the show, which is down from about 200 at last year's LinuxWorld, said Rob Schescherareg, a vice president of sales, marketing and product development at Boston-based IDG, which runs the event. Some of the decrease is due to the economy, because some of pure-play Linux companies no longer exist, he said. IDG expects up to 19,000 visitors to the show, down from about 25,000 last year."

"As the Linux community prepares to congregate next week in New York for the LinuxWorld Conference and Expo, the center of attention, as always, will be Linux creator Linus Torvalds. A little more than a year ago Torvalds released the 2.4 kernel and has spent much of the year working on numerous 2.4.x versions to further stabilize and strengthen Linux. After handing the 2.4 kernel over to Marcelo Tosatti to maintain late last year, he turned his attention to the 2.5 development tree. Torvalds took time out to exchange e-mail with eWEEK Senior Editor Peter Galli about his work on and vision for 2.5." Read the interesting Q&A at eWeek.

"What is real time? This article, first of a three-part series, introduces the benchmarks we'll run on real-time Linux version in the next two issues. Linux is well tuned for throughput-limited applications, but it is not well designed for deterministic response, though enhancements to the kernel are available to help or guarantee determinism. So-called real-time applications require, among other things, deterministic response. In this article I examine the nature of real-time applications and Linux's strengths and weaknesses in supporting such applications." Read the rest of the story at LinuxDevices.

""The Heist." A panicking manager type leads police detectives into what appears to be an empty server room. "It's the crime of the century!" the balding, middle-aged, middle manger exclaims over cheesy adventure-movie background music. "Everything's gone!" "What was stolen?" asks one of the cops. "Everything," the pointy-haired boss answers, "payroll, R&D, customer records ..." Of course, our hero, a scruffy-looking geek boy, saves the day. He points to a mainframe in the back of the room, and says, "We moved everything onto that one. It's going to save us a bundle. I sent out an email ... " The music swells, and the announcer says something about IBM servers running Linux saving you a bundle. What the commercial doesn't tell you is that the spendy IBM server in the commercial is running multiple copies of Linux at one time as virtual machines."

"For desktops, the 2.4 version of the kernel is just fine. If you have heavy-duty processing needs, 2.4 has been a series of disappointments. Sysadmins of big iron have two choices -- go back in time or play upgrade hopscotch. Both have problems. Let's start from the beginning. In July 2001, I was responsible for upgrading a customer's server from Red Hat 6.2 to Mandrake 8.0. The machine was built from scratch, and Mandrake was installed onto a freshly formatted RAID 5 array. We then migrated the Red Hat 6.2 applications to the new machine."

Slashdot mentions a new interview with Linux kernel hacker Rik van Riel by Andrew Scrimieri, available in Italian and English. Rik currently works for Conectiva and wrote the kernel virtual memory subsystem used in Linux 2.4 until recent versions, when Linus Torvalds replaced it. He talks about friction regarding the VM, VM specifics, kernel politics and multiple kernel trees, the kernelnewbies project, and the DMCA.

wxWindows is a cross-platform applications framework available under a free license. Early this year marks wxWindows 10th birthday, and to mark this event codingstyle.com has an exclusive interview with several key developers of the project.

From NewsForge: "According to its website, the goal of theKompany is "to provide developers with powerful, easy-to-use tools for creating equally powerful and useful software for the world's leading open-source operating system, Linux -- and thereby ensure the long-term success of Linux." To find out more about theKompany and its plans for supporting Linux on the corporate and home desktop, DesktopLinux.com spoke with theKompany President and Founder, Shawn Gordon."

"If KDE and GNOME are the Hatfield and McCoy of Open Source graphical desktop environments, then theKompany.com and Ximian are not exactly kissing cousins. But the philosophical beliefs of the two businesses are converging, and the community is settling down to a broader acceptance of commercial software. Assuming computer users choose their desktops before they choose their desktop applications, ostensibly theKompany's and Ximian's target markets are non-intersecting sets. But their business practices and philosophies on Open Source have been scrutinized, discussed and compared at length in public." Read the editorial at NewsForge.

The 2002 is here and everyone's seems busy writing editorials as to what it might bring to Linux. Some are optimistic, others are not so much. Judging from the amount of the... almanac Linux articles on the web, one thing is for sure: people are worried about its further success. Newsforge says (wisely) that Linux doesn't have to beat with Windows while ZDNews has three articles already: "Is it time for Linux on the desktop?", "2002 prediction: Linux won't make it this year" and "Will Linux survive the dot-com crash?"

Kerneltrap interviewed Dave Jones who currently lives in London, employed by SuSE as a Linux kernel hacker. In the past six months since he graduated from the University of Glamorgan he has gotten involved in an impressive range of kernel related projects, including Powertweak, x86info, OProfile and the Kernel Janitors Project. Additionally, he maintains a -dj patch for the 2.5 development kernel, helping to sync it with the stable 2.4 kernel as well as offering increased stability.

At the time I was writing this article, the Linux kernel 2.4.17 was released only 3 days ago and these holly days you may find some more time to experiement with it. The following article includes step-by-step instructions on how to compile a Linux 2.4.X kernel, an article mostly targetting people who have never dared to compile their own kernel yet. Read on and we promise, it is not that hard to do so.

"It wasn’t so long ago: 1999 and 2000 saw a great deal of innovation and interest, not to mention hype, about the Linux open-source operating system, and by extension, open-source software in general. This year the focus has been more on other technologies, such as application servers, portals, distributed component models and Web services. Does anyone still care about Linux? And if so, why the seemingly deafening silence? It seems that the open-source system moves past hype to serious implementation." Read the rest of the interesting editorial at SDTimes.

TimeSys Linux GPL is a full Linux distribution for all supported embedded boards that includes everything needed to develop, deploy, and maintain an embedded platform, including not only (according to the company) the world's lowest-latency Linux kernel, but also all the libraries, tool chains, utilities, drivers, scripts, and documentation, all distributed under the GNU General Public License (GPL). TimeSys Linux GPL consists of a powerful, fully featured, preemptible Linux kernel and all other components needed to extend a standard Linux distribution to support predictable, extremely low-latency response. The fully preemptible capabilities mean the kernel has bounded, mutex-based kernel locking with a new fixed priority scheduler, schedulable (meaning the developer sets the priorities) interrupt handlers, and schedulable extended interrupt handlers, including the IP stack.
