It's been a very busy month in The Coding Studio's Linux screenshots department. This month we installed and grabbed some cool screenshots many Linux distributions, including Ubuntu 9.10 Karmic Koala Alpha 2, Fedora 11, Guadalinex 6, Calculate 9.6, MoLinux 5.0 and Tiny Core 2.0, as well as these Linux newcomers: Debris 1.8.3, Wires Cut 9.04, BlankOn 5.0 and InfraLinux 9.04. Enjoy!

Debugging is the process of finding and reducing the number of bugs in computer software and electronic hardware. When a program crashes, the debugger shows the position in the original code. A good debugger plays an essential role in software development. This article examines three different types of debuggers: source-level debuggers, memory debuggers and bug tracking software. To provide an insight into the quality of software that is available, we have compiled a list of 9 advanced Linux debugging tools. Hopefully, there will be something of interest here for anyone who wants to fix, and help fix, bugs.

When working on the beta of Officeshots.org I ran into an interesting problem with file type and MIME type detection of OpenDocument files. When a user uploads an ODF file to Officeshots I want to determine the MIME type myself using the PHP Fileinfo extension. On Linux, the PHP Fileinfo extension relies on the magic file that is provided by the file package. The magic file contains a series of tests that can determine the file type and MIME type of a file by its contents. I found out that the magic file is incomplete for OpenDocument files. In this article I will show you what is wrong with the magic file and how you can fix it.

On behalf of the KDevelop team I am happy to announce the Beta 4 release of KDevelop 4. This release includes some major new features, such as working sets (only available when building with KDE 4.3), integration of the quickopen functionality into the toolbar and a new perspective switcher (see the upper right corner of the mainwindow).

This Howto covers the installation of XenServer 5.5.0 and the creation of virtual machines with the XenCenter administrator console. XenServer is a free virtualization platform from Citrix, the company behind the well known Xen virtualization engine.

The XenServer installation CD contains a full Linux distribution which is customized to run XenServer.

1. Use !! Typing !! followed by Enter will bring back and execute the last command (same as Ctrl+P followed by Enter). 3. Make manual pages coloured I think this tip is a productivity tip because once a manual page is shown coloured, it is easier, clearer to read. Just add the following inside the ~/.bashrc file, where ~ is your home directory:

After taking a closer look at the "Animations" panel located inside "CompizConfig Settings Manager". I took a close look at the “Window Match” string and compiled my own string to include as many “Window Match” keywords as possible.

When Germany's third largest city gives Microsoft the brush-off, it excites comment in the USA. Munich got itself into the American newspapers a few years ago when the city council decided to initiate project LiMux, aimed at gradually banishing Microsoft programs from the town hall computers. While talk about the software revolution has now died down, the changeover is being enthusiastically pursued. Other local authorities have now followed suit. Microsoft, however, won't leave the field without a fight. "We are able to learn", said Andreas Hartl, Director Platform Strategy of Microsoft Deutschland.

After having gone to the community for looking at names, Red Hat has announced that the release of Fedora 12 will be codenamed Constantine. This name had the most votes and was approved by Red Hat's Legal department of being free of any potential issues...

We are proud to announce a new version - 0.95 - of our live DVD at Linuxtag 2009 in Berlin.

The Drupal content management system is one of the most popular engines for dynamic websites — indeed, it powers the site you're visiting right now. All this powering doesn't happen by itself, though, and the developer community that does the dirty work behind the scenes is in need of a bit of Linux labor. The Testing and Quality Assurance team at Drupal are "the plumbers who keep the community plumbing from leaking." While they once spent their time reviewing patches one-by-one to assure stability, they now employ a testing bot to automatically apply patches to test installations, freeing up tester time to tackle greater things.

Calculate Directory Server is a Gentoo-based LDAP server providing a centralised storage of application settings, user accounts and access privileges. A new version of the product was announced yesterday. Some of the main changes include: "Support for Italian and Polish languages; support for the proxy service with user authorization in LDAP; support for Samba group settings in the LDAP server; support for setting of some Jabber service hosts; isolinux has been used for booting; when booting from CD user can now select a keyboard layout; support from loading the CD into memory; improved hardware compatibility when booting from a USB DVD...."

The Debian project is pleased to announce the second update of its stable distribution Debian GNU/Linux 5.0 (codename "lenny"). This update mainly adds corrections for security problems to the stable release, along with a few adjustment to serious problems. Please note that this update does not constitute a new version of Debian GNU/Linux 5.0 but only updates some of the packages included. There is no need to throw away 5.0 CDs or DVDs but only to update via an up-to- date Debian mirror after an installation, to cause any out of date packages to be updated.

FreedomHEC (Freedom Hardware Engineer's Conference) Taipei was held June 10 and 11 in, unsurprisingly, Taipei, Taiwan. The event, sponsored by the governmental Institute for Information Industry, followed the huge Computex conference in the hope of attracting hardware developers who are interested in supporting Linux. Your editor, who had the honor of being invited to speak at FreedomHEC Taipei, would assert that the goal was achieved; over 200 developers showed up for two days of technical talk about the Linux kernel and the best ways to contribute to it.

absolute Paul Sherman has announced the availability of the first release candidate for Absolute Linux 13.0, a lightweight modification of Slackware Linux for the desktop: "Absolute Linux 13.0 RC1 released. Pre-release that includes fixes for slapt-get and wicd, addition of a control panel, centralizing control and eliminating the sometimes confusing utilities menus. Big updates to Midori and Inkscape on repositories (under /CD2). New theme, new log on, Qt 4 up and running, several new applications along with Qt 4-based K3b. Overall a more cohesive look and simpler navigation. Wanted a release candidate so that 13.0 will not necessitate updates -- also wanted to have feedback on whether Midori is functional enough to become the default browser. (It uses about 1/3 the memory of Firefox in my tests.)"

OpenVZ project leader Kir Kolyshkin clarified at LinuxTag 2009 that the software also lends itself to Linux resource management. The facts are clear, Koyshkin said at the outset: every computer has but finite resources such as CPU time, memory, hard disk size and I/O, and network I/O. Administrators are interested in protecting these resources from DoS attacks so that they can continue providing QoS or simple processing.

Determining which software we use can be a very social experience, often we’ll ask our friends what they recommend, so why not take this social aspect to the (currently) most popular social networking site?

molinux MoLinux 5.0, a Spanish, Ubuntu-based distribution developed by the regional government of Castilla la Mancha in Spain, has been released. Code-named "Dorotea", in reference to a pretty girl in Cervantes' Don Quijote de la Mancha, MoLinux 5.0 is distributed as an installable live DVD. New features: improved hardware support and boot speed; optional ext4 file system support; connectivity improvements with the latest version of NetworkManager; newest versions of most of the included applications. New software: GNOME Control Centre for configuring the system; CompizConfig, a utility for setting up 3D desktop effects; Tucan, a download manager; Gru, a tool for restoring the bootloader in case it has been accidentally overwritten or damaged....

LUK, Linux Unified Kernel, is it the future of the Linux desktop? It promises us the ability to run Windows drivers natively on Linux, but why are so many in the community against it?
