File Alteration Monitoring Techniques under Linux

In a multi-user, multi-process operating system, files are continually being created, modified, and deleted, often by apparently unrelated processes. This means that any software that needs to keep aware of what is happening in a filesystem needs to employ a file monitoring technique. Monitoring, in this sense, means keeping a watch over a set of files, waiting for any of them to change. Read the article at DevChannel.

Kernel Maintainer: Linux 2.6 Delivering on its Promise

Andrew Morton, 2.6 kernel maintainer, can be forgiven if he's a little blasÉ about this week's maintenance 2.6.6 release. Morton, who said he's handling a fraction of the kernel changes these days, is mucking his way through a heavy load of more than 140 a week. "This is a large volume of changes, a much higher rate of changes than earlier kernels," Morton told SearchEnterpriseLinux.com Wednesday afternoon. "We've just got our processes sorted out better now." Read his interview here.

Pleasantly Surprised with Knoppix Linux

I've been trying Linux on and off for a couple of years. My first experience with Linux was with a version of Slackware (can't remember) way back in 1996. At the time the installation was so daunting that I gave up all together. For a little background I consider myself a proficient computer user.

Mandrake, SuSE Offer New Linux Features

MandrakeSoft S.A. and Novell Inc.'s SuSE Linux division, recently shipped new versions of their respective mainstream Linux distributions, both based on the new Linux 2.6 kernel. eWEEK Labs tested Mandrakelinux 10 PowerPack+ and SuSE Linux 9.1 Professional—which each began shipping last month—and we were impressed with their ease of use and with the broadness of their capabilities.

Linux Kernel 2.6.6 Released

Linus Torvalds announced the release of the 2.6.6 stable kernel. A number of notable additions found their way into the mainline 2.6 kernel during this development cycle, including Jens Axboe's laptop mode and the completely fair queueing (CFQ) I/O scheduler, support for a non-executable stack on a number of architectures, several patches laying the groundwork for object-based reverse mapping, and 4KB kernel stacks for the i386 architecture reducing the kernel's per process overhead, KernelTrap reports.

Commentary: Why the markets still don’t trust Linux

Linux has only recently begun to regain credibility in the financial markets since its speculative debut. However, its licensing model, hefty competition, and lack of maturity still worry investors. Companies such as Red Hat, long past its 1999 speculative highs, are slowly gaining ground while other Linux companies, such as Linspire, are planning initial public offerings. Is Linux finally becoming a viable alternative to proprietary operating systems, or is this rise simply a byproduct of a mini-tech bubble?

SpecOps Lab’s David Screenshots

SpecOps Labs has sent Flexbeta a few screenshots of “David” in action. David is the codename for a middleware application that sits on top of Linux to enable it to run Windows applications. This is the first time that "David" has been shown to the public (which apparently is nothing but WINE, but SpecOps managed to make a lot of fuss in the media about this "new technology" without mentioning WINE).

Resellers Question Linux on the Desktop

Resellers are enthusiastic about recent moves by Novell and Red Hat to move Linux onto the desktop but warn that fear of the unknown and missing applications are holding progress back. Asked if he thought Linux was ready to grace the desktops of the average business Philip Burgess, sales manager at Sire Technology, said: "Blimey, I've just put the phone down after talking to SUSE Linux - I'm going to see them next week."

Linux: Random File I/O Regressions In 2.6

A recent discussion on the lkml looked into a reproducable random file I/O regression in 2.6 compared to the 2.4 kernel. Alexey Kopytov posted the benchmark results, attempting to simulate the workload of a database under intensive load. The tests were tried with all I/O schedulers, including the anticipatory, deadline and CFQ, and in all cases 2.4 outperformed 2.6. Read the report at KernelTrap.
