Here are just a couple of screenshots from Leopard and explanation of some of the new features.

This chapter explains the ins and outs of non-standard FreeBSD installations. If you are installing FreeBSD on a system with another operating system previously installed, or if you aren't using a CD or DVD to install FreeBSD, you'll want to read this chapter before performing the installation.

If you're old enough to remember the 1970s, the current popular fascination with fractals probably flashes you back to those halcyon days of big hair and wild imagery. Whatever your age, you'll enjoy Peter Aitken's explanation of how fractals work. You can even plug in his Visual Studio demo program and make some fractals of your own.

The driver source code released for the Intel 965 Graphics chipset recently isn't as open as first thought. Keith Packard posted a reply on the linux-kernel mailing list detailing what parts were not available.

OpenBSD strives to be the most secure UNIX derivation. Design principles, such as code auditing, extensive use of encryption, and careful configuration choices, combine to ensure OpenBSD's secure by default philosophy holds true. This article gives you a close look at the operating system so secure that it was once banned for use in a DEF CON competition, where crackers go after each other's systems.

"Overall, FC6 looks and feels like a more solid, polished version of FC5 rather than a wholesale revamp. I look forward to the finished product this fall." Check the short commentary here.

Statement by ATI: "For other markets, such as workstation and consumer, performance and feature differentiation are key metrics. Proprietary, patented optimizations are part of the value we provide to our customers and we have no plans to release these drivers to open source. In addition, multimedia elements such as content protection must not, by their very nature, be allowed to go open source."

Between the full desktop version, the subscriber's ad-free version, the normal mobile version (via autodetection), the very lite mobile version and the WAP version of OSNews, here is one more: http://osnews.com/pda . This version is built around our RSS feed and it's geared towards cellphones (like the Motorola RaZR line) that can't quite manage to render our normal mobile front page (28 KB overall) while the very lite or WAP versions don't have enough information in them so they leave our readers with a bitter taste. Hence, we implemented this RSS-based middle-ground mobile version, like we also did for other popular sites yesterday (screenshots). The PHP source code that generates this mobile-friendly layout is freely available and ready to be deployed, courtecy of MoBits.com.

"August 12, 1981 marks the birth of the IBM PC, the computer that single-handedly turned personal computing to the business market. IBM's success forced Apple and others to change their focus, and most personal computer companies from the pre-IBM era have become historical footnotes. By 2006, even Apple Computer had followed IBM's lead and adopted Intel CPUs and built Macs that can boot Microsoft Windows." Yes, boys and girls, she's that old. A 'thank you' is in order, I suppose.

The Haiku news just keeps on coming lately. "HaikuLiveCDScript is a shell script to build a Haiku live CD. It downloads, decompresses, and generates a boot image and drops files in a folder ready to be burnt. Just unpack the script files and execute 'makelivecd', and wait a while."

"The GNU Linear Programming Kit is a powerful, proven tool for solving numeric problems with multiple constraints. Get an introduction to GLPK, the glpsol client utility, and the GNU MathProg language to help find the best solutions to complex numeric problems. Then, learn to solve the problem of optimizing the operations for Giapetto's Woodcarving, Inc., a fictional toy manufacturer."

"Four short years ago, Microsoft unveiled its new framework/engine for programming and running applications in a virtual environment, and the world was stunned. Microsoft had introduced a run-time environment that was for the first time a true 'write once, run everywhere' implementation, but that was far from being the end. With .NET 3.0 on the loom, NeoSmart Technologies takes a look at how far .NET has come and just how long it can keep going."

Ars does its usual thorough stuff on the new Mac Pro. According to Ars: "The interior layout is a big win for Apple. Four drive bays is adequate for a pro tower, and the fact that each drive is on its own bus is a smart design decision. It's also great having room for a second optical drive. In terms of performance, it's good news - with a caveat. While the fully-buffered memory, the screaming-fast Xeon 5150s, and the 1333MHz FSB are all great, Apple's video card choice is most definitely not. It doesn't fit, and it detracts from the overall experience. Despite that, the Mac Pro is a very solid graphics or video editing workstation. When all the major 'pro' applications have made the transition to Universal Binaries, the PowerPC years will be little more than a memory."

Novell chief technology officer Markus Rex has hit back at criticism the company included an 'unstable' Xen virtualisation environment in its new Linux server, pointing to support from hardware partners. "We had all the major hardware partners that had virtualisation hardware like IBM, Intel and AMD. They all stood up and said 'Yes, this technology's ready, and we fully support deployments based on Xen and in combination with SUSE Linux Enterprise 10'."
