"The Fedora Project is pleased to announce the release of the fourth and final test release of Fedora 7! Test 4 is for beta users." Announcement and release notes here. Update: Screenshots.

According to kerneltrap: "The future of Reiser4 was raised on the lkml, with the filesystem's creator, Hans Reiser, awaiting his May 7th trial. Concerns that the filesystem wasn't being maintained were laid to rest when Andrew Morton stated, 'the namesys engineers continue to maintain reiser4 and I continue to receive patches for it.'"

"Apple Inc. surpassed even the most optimistic forecasts for its usually tepid second quarter, delivering an 88 percent increase in profit on strong sales of Macintosh computers and iPod music players," Laurie J. Flynn reports for The New York Times." There were 1.52 mil Macs and 10 mil iPods sold in the quarter. Elsewhere, check this article on Macs in the enterprise.

Linux Kernel 2.6.21 has been announced. Linus writes: "So the big change during 2.6.21 is all the timer changes to support a tickless system (and even with ticks, more varied time sources). Thanks (when it no longer broke for lots of people ;) go to Thomas Gleixner and Ingo Molnar and a cadre of testers and coders." More info here and here.

"Last Wednesday, a company called Falling Leaf Systems announced the availability of an alpha of something called the Alky Project. The Alky Project has a lofty goal: to liberate DirectX 10 gaming from the confines of Vista and bring it first to Windows XP, and then to Linux and OS X. The project plans to do this by building a converter that can take in a DX10 game executable and spit out a modified version that can be run on a (non-Vista) target OS. The target OS must be x86-based, which rules out the PPC version of OS X, since the converter doesn't do any binary translation."

"One of the many new technologies for KDE 4 is the often mentioned, but seldom explained Solid hardware API. Hardware has always been a bit of an annoying element of using Linux and other UNIX-like operating systems, but Solid hopes to fix that for KDE 4. In many ways, Solid is like Phonon, in that it's a Qt/KDE style API around already existing components at the lower level, such as freedesktop.org's HAL. It is already quite functional in the backend, and it's already affecting visible KDE components."

"Desktop search engines are all the rage these days. While Beagle may be the most popular desktop search engine for Linux, there are alternatives. If you are looking for a lightweight and easy-to-use yet powerful desktop search engine, you might want to try Recoll. Unlike Beagle, Recoll doesn't require Mono, it's fast, and it's highly configurable. Recoll is based on Xapian, a mature open source search engine library that supports advanced features such as phrase and proximity search, relevance feedback, document categorization, boolean queries, and wildcard search."

"More than half of the 1.2 million lines of code for the real-time kernel technology have been moved into the mainline Linux kernel over the past year, Tim Burke, the director of emerging technologies at Red Hat, said at the Linux/Open Source on Wall Street conference on April 23."

Xandros today announced that Xandros Server 2.0 is the first product to be certified by the Linux Foundation through use of the LSB Distribution Testkit. Xandros engineers worked closely with their Linux Foundation counterparts in perfecting the new, automated testing procedures that will facilitate broad application developer support to Xandros Server 2.0 and all other standards-based Linux operating systems.

"Jailing is a mechanism to virtually change a system's root directory. By employing this method, administrators can isolate services so that they cannot access the real filesystem structure. You should run unsecured and sensitive network services in a chroot jail, because if a hacker can break into a vulnerable service he could exploit your whole system. If a service is jailed, the intruder will be able to see only what you want him to see - that is, nothing useful. Some of the most frequent targets of attack, which therefore should be jailed, are BIND, Apache, FTP, and SSH. SSHjail is a patch for the OpenSSH daemon. It modifies two OpenSSH files (session.c and version.h) and allows you to jail your SSH service without any need for SSH reconfiguration."

"If you're an OpenSolaris x86 user and are using a NVIDIA graphics card with NVIDIA's binary Solaris drivers, you can now enjoy Compiz on your desktop. Erwann Chenede has produced packages of Compiz 0.5.0 for OpenSolaris x86. In fact, to ease the process he has even written an OpenSolaris install script for Compiz. More information (download links) is available from Erwann's Sun Blog."

"Today, IBM announced a public beta trial of a virtual Linux environment that will let x86 applications run on its System p Unix servers without modification. The new IBM System p Application Virtual Environment technology will allow x86 binaries to run as well without modification, removing the biggest barrier against effective virtualization for some companies. As a result, customers will be able to consolidate dozens, if not hundreds, of servers into one virtual environment."

Recently a change in the Linux virtualization landscape has appeared with the introduction of the Kernel virtual Machine. KVM supports the virtualization of Linux guest operating systems - even Windows - with hardware that is virtualization-aware. Learn about the architecture of the Linux KVM as well as why its tight integration with the kernel may change the way you use Linux. Update: An interview with the KVM lead developer.

"Clive Sinclair's ZX Spectrum is a quarter of a century old today. The machine that really launched the UK IT industry hit the streets of a depressed Britain on 23 April, 1982. Dark days, then. But lo, along came bespectacled Messiah Sir Clive Sinclair with the successor to his 1981 release, the black-and-white ZX-81. The ZX Spectrum boasted a visual cortex-melting eight colours at 256 x 192 resolution, blistering 3.5MHz CPU, and crucially, a crisp-repelling vulcanised rubber keyboard."
