Strict Open Source Kernel Policies Give an End to a Driver

Linux kernel maintainers removed hooks from a semi-binary driver (half open, half closed) for Philips webcams. This has angered the developer of the driver who have worked on the driver for 5 years, resulting on removing the driver completely from the kernel and his site. The developer has an NDA with Philips and he can't fully open source the driver, even if he wanted to. The losers from the whole story, are the users.

Is Linux too good to be true?

"Typing "Linux" into Google gives about 109 million results. Surprisingly, that's five million more than searching for "Microsoft". But are potential users of the alternative operating system to Windows being enticed into making a decision they may later regret? Some Windows users are increasingly disillusioned with their computers. The internet no longer feels safe, thanks to viruses, spyware, trojans, hackers and pop-ups targeting features (and failings) in Microsoft software. Going online these days using Internet Explorer is like walking into a minefield." Read the article at Independent.

Migrating from Linux Kernel 2.4 to 2.6 on POWER

One of the benifits you get when migrating from Linux Kernal 2.4 to 2.6 is improved stability. The process for loading kernel modules in and out of the kernel was improved. This article highlights and shares information on that and the other differences between the Linux kernels 2.4 and 2.6 including new features of Linux Distributions for POWER5-based systems, SUSE LINUX Enterprise Server 9 (SLES 9), and Red Hat Enterprise Linux Advanced Server 3.

Kernel debugging with Kprobes

Collecting debugging information from the Linux™ kernel using printk is a well-known method -- and with Kprobes, it can be done without the need to constantly reboot and rebuild the kernel. Kprobes, in combination with 2.6 kernels, provides a lightweight, non-disruptive, and powerful mechanism to insert printk's dynamically. Logging debug info such as the kernel stack trace, kernel data structures, and registers has never been so easy!
