This post is the second in a series on shell script debugging, error handling, and security. The content of this post will be geared mainly toward BASH users, but there will be information that’s suitable for users of other shells as well. Information such as techniques and methodologies may transfer very well, but BASH specific constructs and commands will not.

Measures to optimise the power management code and fully support the Turbo Core function of recent AMD six-core processors increase the data throughput and processing speed of Linux 2.6.35. Further kernel additions include tracing interfaces for KVM, another kernel configuration program, and functions for de-fragmenting the working memory

KDE SC 4.0 was released in January of 2008 and KDE SC 4.5 will be released shortly (August 4th, 2010), roughly two and a half years later, and it is time to reflect on what KDE SC 4 seeks to accomplish and how well it is doing in its goals. The critical shift KDE SC took in this series is abstracting the desktop from the underlying system through three pillars, Phonon, Plasma and Solid making the desktop some sort of a virtual platform environment and easily portable to other operating systems.

Support for transparent spreading of incoming network load across CPUs, Direct-IO support for Btrfs, an new experimental journal mode for XFS, the KDB debugger UI based on top of KGDB, improvements to 'perf', H.264 and VC1 video acceleration in Intel G45+ chips, support for the future Intel Cougarpoint graphic chip, power management for AMD Radeon

PulseAudio is a Linux sound server that, through abstraction layers, promises a myriad of flexible audio features: combining multiple sound cards into a single, multi-channel device, changing output devices on the fly for running applications, even redirecting input and output between machines over the network.

This guide explains how to set up mod_chroot with Apache2 on a CentOS 5.4 system. With mod_chroot, you can run Apache2 in a secure chroot environment and make your server less vulnerable to break-in attempts that try to exploit vulnerabilities in Apache2 or your installed web applications.

With version 5.2.14 as the final point release, the developers have discontinued their regular support of PHP 5.2. Users are advised to switch to 5.3. Version 5.3.3 was also released earlier today
