"This document provides an introduction to NFS as implemented in the Linux kernel. It links to developers' sites, mailing list archives, and relevant RFCs, and provides guidance for quickly configuring and getting started with NFS on Linux. A Frequently Asked Questions section is also included. This document assumes the reader is already familiar with generic NFS terminology. "

AMD AND REDHAT have just done the so called impossible, and demonstrated VM live migration across CPU architectures. Not only that, they have demonstrated it across CPU vendors, potentially commoditising server processors. Eeek!

The concept is simple, click a button, and your VM moves from one machine to the next. The execution for similar architectures has been done for ages, AMD can do it from E-Step Opterons to a promise of Magny Cours. Intel is a little more restrictive, but they can do it between iCore iNumber iNumberals as iwell.

This is a benchmark report from GraphicsMagick's offical website. I record it here just for a quick refer, I may need it in the following days. As it's from GraphicsMagick itself, simply dont trust the results, just pay more attention on how they performed their benchmark.

These three are all in-memory file-system. Sysfs was originally based on ramfs. ramfs was written around the  Linux 2.4 time. It's an exercise in elegance, as it showed just how easy it was to write simple filesystem using the VFS layer. Because of its simplicity and use of the VFS, it provided a good base from which to derive other in-memory based filesystems.

This is a quick guide for installing eAccelerator in a PHP environment. eAccelerator is well-known PHP memory management plug-in, it's used to optimize execution of PHP codes.

   1. Download the latest version from sourceforge.net (http://sourceforge.net/projects/eaccelerator/), and decompress it into sources code.

dig (as known as "domain internet groper") is a utility that can talk directly to name servers in order to gather detailed domain name related information.

It's been more than 18 months since Hitachi reached the terabyte mark with the Deskstar 7K1000. In that time, all the major players in the hard drive industry have spun up terabytes of their own, and in some cases, offered multiple models targeting different markets. With so many options available and more than enough time for the milestone capacity's initial buzz to fade, it's no wonder that the current crop of 1TB drives is more affordable than we've ever seen from a flagship capacity. The terabyte, it seems, is old news.

Project Euler is a series of challenging mathematical/computer programming problems that will require more than just mathematical insights to solve. Although mathematics will help you arrive at elegant and efficient methods, the use of a computer and programming skills will be required to solve most problems.

The motivation for starting Project Euler, and its continuation, is to provide a platform for the inquiring mind to delve into unfamiliar areas and learn new concepts in a fun and recreational context.
