Dr. Dobbs Journal has published a detailed, technical paper chronicling a successful 22-month development effort by two Intellibot Robotics software engineers to port a $33,000, autonomous floor-scrubbing robot from an OS-less design based on a custom 68K processor-based board to embedded Linux running on an off-the-shelf x86-board.

Imagine being able to reboot a server from the system console from Europe or at an airport during a layover. Imagine not having to physically be present at your datacenter to perform tasks that require console access but, instead, doing them in the comfort of your own home or office. Now imagine doing all this with relatively low-cost commodity components running your favorite Unix-variant operating system along with an open source software package.

The creators of the Macintosh-centric podcast "CastaBlasta," have launched their latest audio show -- the weekly "Linux Action Show," dedicated to Linux and related open-source topics.

Microsoft's Windows Small Business Server 2003 R2 will face more Linux competition when it ships later this summer.

Behind the scenes on Wall Street, who is really using Linux? Although developers remain the major practitioners, Linux is also making headway these days as a grid platform for transaction processing, a place for running algorithmic trading engines, and even as a desktop environment, according to participants in this week's SIA (Securities Industry Association) conference in New York City. Jacqueline Emigh reports.

Normally, we expect new Linux desktop users to come from the ranks of disgruntled Windows users. After all, they're the ones who have to deal with high-prices and endless security problems. Now, it seems that some Mac gurus are also making the switch to Linux.

When istockphoto.com launched in February 2000, the images in its database were available free of charge, and the entire company ran on one server with an Access database. "At that time, traffic was very low," says istockphoto.com Executive Vice President Patrick Lor. In 2002, the company moved to a fee structure and wanted to increase traffic. "We came across this amazing thing that looked like enterprise-grade software, called MySQL." With that and PHP, they re-coded the entire site, and in 2002 sold 154,000 images at 25 cents each. "We went to two generic servers and had an amazing year," he says. "That was our first real exposure to fee structures and the reception was incredible."

Hyperic, a maker of an open-source management platform, this week announced it has joined other open source advocates in their efforts to make using open source management tools in large enterprise networks easier.

Linux vendor Xandros Inc is lining up new business desktop and server releases for the coming months as it looks to establish itself as the Debian distribution of choice for the enterprise.

From Page #2: "According to Hoover's, RHAT dominates the market for Linux, the open-source computer operating system (OS) that is the chief rival to Microsoft's Windows operating systems. In addition to its Red Hat Enterprise Linux OS, the company's product line includes database, content, and collaboration management applications; server and embedded operating systems; and software development tools."

Plucky little Belgium. Always the scene of upheavals across the centuries, and sometimes the place where gigantic battles have been fought. Now this David amongst European countries could be risking the wrath of that Goliath of software companies, Microsoft. The Belgian government's decision to use only open formats for exchanging documents is pure common sense. The whole reason for having standards bodies and the standards they produce is to guarantee compatibility and stability above individual companies' commercial concerns. Millions of Euros of taxpayers' money is spent funding bodies like ISO, so it would be foolish to then ignore the work they do.

Linux is an operating system that was initially created as a hobby by a young student, Linus Torvalds, at the University of Helsinki in Finland. Linus had an interest in Minix, a small UNIX system, and decided to develop a system that exceeded the Minix standards. He began his work in 1991 when he released version 0.02 and worked steadily until 1994 when version 1.0 of the Linux Kernel was released. The kernel, at the heart of all Linux systems, is developed and released under the GNU General Public License and its source code is freely available to everyone. It is this kernel that forms the base around which a Linux operating system is developed. There are now literally hundreds of companies and organisations and an equal number of individuals that have released their own versions of operating systems based on the Linux kernel.

[This Bangladeshi news site (in English) has managed to produce a reasonably accurate intro to GNU/Linux. I thought OpenBSD is "UNIX" though. Otherwise, a good intro for newbies - dcparris]

Thomas Gleixner and Ingo Molnar [interview] posted an update of their high-res timerskernel patches for the 2.6.17 kernel, "upon which we based a tickless kernel (dyntick) implementation and a 'dynamic HZ' feature as well".

HPCwire and IDG World Expo have announced the addition of an HPC Linux Cluster Showcase as part of the LinuxWorld Conference & Expo San Francisco. The HPC Linux Cluster Showcase will include a series of vendor spotlight kiosks surrounding a presentation theatre that will feature speakers from organizations that have implemented an HPC Linux Cluster solution. The showcase will bring a unique focus towards the high end of computing and the role of HPC Linux cluster solutions to the LinuxWorld event.
