The town of Steamboat Springs in Colorado is migrating to Linux. The man behind the move explains the challenges and the motivation behind the move
A recent discussion and series of patches on theLinux Kernel mailing list looked at removingrelayfs [story], moving its functionality into an API using sysfs. Paul Mundt offered the patches summarizing, "this is a small patch set for getting rid of relayfs, and moving the core of its functionality to kernel/relay.c. The API is kept consistent for everything but the relayfs-specific bits, meaning people will have to use other file systems to implement relay channel buffers." The thread offers more explanation as to the benefits of the change, with quite a number of people supporting the patches.
Relayfs is described as "a bunch of per-cpu kernel buffers that can be efficiently written into from kernel code. These buffers are represented as files which can be mmap'ed and directly read from in user space. The purpose of this setup is to provide the simplest possible mechanism allowing potentially large amounts of data to be logged in the kernel and 'relayed' to user space." It was originally merged into Andrew Morton [interview]'s -mm tree in January of 2005 [story], and finally made it into the mainline kernel with the release of 2.6.14.

Security experts today warned of a Linux network worm that exploits holes in the Mambo content management system and the PHP XML-RPC library. Dubbed Mare.D, the worm leaves multiple backdoors on infected systems. Two of these are connectback shell backdoors that link to a remote host, while a third allows the malware's writer to access and control infected systems via IRC.
Forty-four years ago, John Hershel Glenn Jr. is successfully launched into space aboard the Friendship 7 spacecraft on the first orbital flight by an American astronaut. Russia had already sent two cosmonauts into orbit at this time. In the many following years Russian and America race each other for space superiority. Much later Russia and America have finally started cooperating in Earth's adventures into space. Competition is good, but collaboration can by so much better.
If you're at home this President's Day, and you want to give some cutting edge Linux a try, this is your lucky day. Both OpenSUSE and Ubuntu have new betas out -- the former, the fourth beta of v10.1; and the latter, the fourth alpha of v6.04.
Working with free and open source software, one frequently hears terms such as bugs, updates, and patches. When developers come across shortcomings in their software, instead of repackaging the software with the changes, they can provide a patchfile that contains details of all required changes. Two important tools used in the process are diff, which creates a patchfile, and patch, which applies it. You can use both tools with text or HTML files. User Level: Intermediate

Speaking to a standing-room only crowd of open source startups, investors and lawyers, Bill Hilf, director of platform technology strategy at the company, outlined why, from a business perspective, Microsoft is involved with open source. Microsoft views open source through the lens of "coopetition from commercial and open-source strategies at the same time," Hilf said.
Coopetition, or simultaneously cooperating and competing with rivals, has long been Microsoft's broader business strategy. But Hilf gave an insight on how open source fits into this plan.
"Making money matters. More importantly, making money sustainably matters. Being a successful commercial software company is very hard ... staying successful is even harder," Hilf said. "Developing coopetition strategies is a great way for growth in this environment and we're seeing that today."
