Changes to the memory subsystem promise improved response times and performance. From Linux 3.2, device-mapper supports thin provisioning and is able to use this ability for improved snapshot functionality.

PowerDNS Authoritative Server is a great choice for handling DNS for your organization. For a successful install (and for this howto in particular) you'll need a Linux server running CentOS. This HOWTO will show you how to get a working pdns nameserver going along with a great web front-end. The most common way to set up PowerDNS (pdns) on multiple servers (ns1, ns2, etc...) is to enable MySQL replication from the master (ns1) and the slave(s) (ns2, ns3). That's going to be part 2 of this HOWTO. Let's just get pdns set up on our master and answering queries for now...

Ubuntu Tweak 0.6 is almost ready and the new version will be getting some cool new features such as Unity settings, an option to change the GTK or icon theme, a package cleaner ("Janitor") and more. The new version will only support Ubuntu 11.10 or later and will come with tweaks for three desktop environments: Unity, Unity 2D and GNOME Shell.

Ladies and gentlemen... Please welcome at this time, The Humble Indie Bundle #4! Pay what you want, help charity, and get some awesome indie games.

Lighttpd is a secure, fast, standards-compliant web server designed for speed-critical environments. This tutorial shows how you can install Lighttpd on a CentOS 6.0 server with PHP5 support (through FastCGI) and MySQL support.

LinuxSecurity.com: Using password guessing as an attack vector. Over the years we've been taught a strong password must be long and complex to be considered secure. Some of us have taken that notion to heart and always ensure our passwords are strong. But some don't give a second thought to the complexity or length of our password.

While Gnome meta-morphed into a tablet/touch based desktop environment, which initially created some ripples, KDE has adopted a more mature approach. The free and open source project is working on what is called Plasma Active.

Pear OS 3.0 provides all the applications you need. Among them we can mention Opera web browser, Empathy instant messaging client, Sylpheed email client, Brasero CD burning utility, Synaptic Package Manager, Shotwell picture viewer and organizer, BleachBit system cleaner, and Back In Time system backup utility.

Unity3D has been one of the early adopters of native client technology. The latest Unity3D development tools now includes a simple checkbox using that developers can make their games compatible with Chrome and NaCl. While Unity3D native Linux support is still not encouraging, this news is definitely exciting. In fact, we already have our first Unity3D demo 'AngryBots' working in Linux using NaCl (made with Unity3D 3.5). The demo runs quite nicely with no lag and fps issues.

Busy week for Red Hat with a pair of new releases, as HP open sources webOS -- will it be the next great mobile Linux?

AMD Catalyst 11.12 also brings support OpenCL MCW SlotMax libraries integration, as well as RandR improvements. Moreover, a few other small improvements and bugfixes are also present in the new AMD Catalyst 11.12.

Android developers can now benefit from ITTIA DB SQL’s bi-directional data synchronization in applications that need to maintain connection with back-end enterprise databases.

Eclipse is a large and powerful IDE, and there are several tactics to help you work faster with it. This article talks about key productivity enhancers.

While CentOS, Scientific Linux, and Oracle Linux Server are all derived from the same upstream source (Red Hat Enterprise Linux), how does the system performance compare between these RHEL derivatives? Here are some benchmarks of each of the 6.1 releases for Oracle Server, CentOS, and Scientific Linux, as they all do not perform the same.

EncFS provides an encrypted filesystem in user-space. It runs without any special permissions and uses the FUSE library and Linux kernel module to provide the filesystem interface. EncFS is open source software, licensed under the GPL.

As with most encrypted filesystems, Encfs is meant to provide security against off-line attacks; ie your notebook or backups fall into the wrong hands, etc. The way Encfs works is different from the “loopback” encrypted filesystem support built into the Linux kernel because it works on files at a time, not an entire block device. This is a big advantage in some ways, but does not come without a cost.

Like all stable releases, Google Chrome 16 brings lots of improvements, like Sync improvements and the ability to add new users and create multiple profiles on a single instance of Google Chrome, as well as the ability to sign-in to Chrome (see the video below for more information).

Gimp 2.7.4 has been released. Latest development release brings many improvements to the single-window-mode, better tablet support specially after updating the brushes engine on tablets like Wacom, and several bug fixes. Hopefully this could be the last development release of Gimp 2.7.x leading to the stable release Gimp 2.8 .

Pay what you want for many awesome games!

The security features in Fedora make it one of my favorite Linux distributions. And that is partly why it is in my list of the top 6 KDE distributions of 2011, even though it takes some tweaking to get it to the it just works state. I will take the security advantages of an operating system over any user-friendliness weaknesses, provided those user-friendliness weaknesses are not show stoppers.

On August 15, LinuxCon celebrated the twentieth anniversary of the Linux kernel with a Roaring Twenties party, complete with swing bands and tuxedos and flapper costumes. The milestone was one that conference attendees were happy to celebrate, despite the obvious embarrassment of Linus Torvalds himself. Unfortunately, 2011 as a whole didn't measure up to those few hours of partying. In fact, whether you are looking at business, the community, or the technology, for free and open source software (FOSS), 2011 was in many ways a disappointing year
