"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."

"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."

"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."

"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."

"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."

"CentOS is an enterprise class GNU/Linux distribution based on the publicly available source packages of Red Hat Enterprise Linux. Just like RHEL or Debian stable, CentOS focuses on stability and security, sacrificing the 'latest and greatest' packages. Is CentOS 5 really that stable? And does it fit on the average Joe's desktop? This is what I'm gonna find out."
