Red Hat takes on VMware with server virtualization solution
Red Hat expanded its virtualization product portfolio this week with the launch of its Enterprise Virtualization for Servers platform. The company touts it as an end-to-end solution which includes management tools and a bare-metal standalone hypervisor that can run both Windows and Linux guest operating systems.
Red Hat aimed to become a major player in the virtualization market last year when it acquired Qumranet, the company behind the Kernel Virtual Machine (KVM). Following the acquisition, Red Hat began transitioning its virtualization strategy towards KVM and away from Citrix’s Xen. KVM has strong backing from the upstream Linux kernel development community, making it a natural choice for Red Hat. The company has invested considerable resources to boost KVM’s capabilities and has built robust management tools around the technology. KVM was practically the centerpiece in Red Hat Enterprise Linux (RHEL) 5.4, which was officially released in September.

Google opens up its JavaScript development toolbox to all
Google is providing the web development community with an intriguing glimpse under the hood at some of the fundamental building blocks of the company’s most popular web applications. The search giant has opened the source code of its comprehensive JavaScript library collection and is making it available to third-party developers for widespread adoption. Google also opened the source code of its own JavaScript compression tools.
The library, called Closure, includes an extraordinarily diverse assortment of capabilities with functionality ranging from JSON serialization to standard user interface widgets. All of the features are cross-browser compatible and can be readily adopted without marginalizing any users. The library consists primarily of helper functions and user interface widgets, many of which are recognizable from popular Google applications.

Apple abandons ZFS on Mac OS X project over licensing issues
Sun’s ZFS filesystem, which the company has referred to as “the last word in filesystems,” was widely expected to be adopted by Apple for use in Mac OS X. However, support never materialized, and the open source project to port the filesystem was unceremoniously shut down last Friday. The (un)stated reasons at heart seem to be licensing issues, though there are also technological reasons why Apple may want to create its own advanced filesystem.
The ZFS filesystem is perhaps one of the first truly “modern” filesystems based on the concept of “copy on write.” In the case of ZFS, this is done at the block level, so when any block on a disk is going to be modified, a fresh copy of all the data for that block is written to a new block on disk, and the older block can be retained for snapshot purposes. The filesystem is meant to address the needs of ever-growing storage, with features like data integrity, integrated device management, instant snapshots, and facilities to deal with increasing concurrency.

Incremental Backup with rdiff-backup
rdiff-backup tries to “combine the best features of a mirror and an incremental backup”. It’s a command line utility that not only gives you a plain mirror of your files, but also allows you to retrieve previous versions of your files using the extra difference data it keeps. This means you can quickly copy and paste to restore a file from your most recent backup, or retrieve the contents of files as they were at the time of any previous backup. rdiff-backup has built in support for network backups over SSH and is network-efficient and fast thanks to its incremental nature. It’s also possible to run rdiff-backup on Windows, soon I’ll be investigating whether it will work as a backup solution for the Windows systems on my network.
Tom has a nice rdiff-backup tutorial. Is there a GUI for all this somewhere?

CentOS 5.3 – Serious Linux for serious people
We will try everything we normally do – from Wireless via Samba sharing to MP3 playback – and then some. I will test four times: two laptops and two installations, one 32-bit and 64-bit. And check everything in KDE and Gnome. This is probably the most extensive test I have done yet. We will practically do everything, from scratch. So not only is this a review, it’s a full blown tutorial to turning your CentOS into a superb desktop.
Some of the stuff waiting you just a few mouse scrolls below:
- Live CD checks on two laptops (Wireless, Bluetooth, Web camera, NTFS support)
- Installation of a 32-bit edition
- Installation of a 64-bit edition
- Solving screen resolution issues
- Compilation
- Installing VMware Tools (in VMware Server and ESXi)
- Configuring startup programs in the session
- Configuring proxy
- Solving update problems via proxy
- Samba sharing
- Adding extra repositories
- Flash Player 10 on 32-bit and 64-bit machines
- MP3, Windows video playback
- Installing cool software (VLC, Skype, others)
- Applications
- Making CentOS pretty (new themes, styles in KDE and Gnome)
And more … until your eyes water from sweet exhaustion. It shall definitely be intriguing. So follow me. Spare an hour or two and have a lovely read.

Setting Firefox 3.5 as default browser system wide in ubuntu
Some applications like TweetDeck don’t respect gnome preferred applications settings and continue to use the older Firefox 3.1 instead of the new one 3.5 when opening links.
This is because
/usr/bin/firefox is currently pointing (like a shortcut) to
/usr/bin/firefox-3.0
To change this to 3.5 enter the following on the command line
sudo ln -sf /usr/bin/firefox-3.5 /usr/bin/firefox
If you want to change it back:
sudo ln -sf /usr/bin/firefox-3.0 /usr/bin/firefox
This will work for Firefox 3.5 as well as Shiretoko 3.5
This will also fix same issues with other Adobe Air applications
