A 5-Minute Talk on The Cell BE Memory Model
The Cell BE processor has both a PowerPC-compliant core and eight SPUs that can access global memory, for a total of nine memory management units. Memory can be accessed through DMA or memory-mapped I/O. It can also be skipped altogether for SPU to SPU transfers. Get the details from Nutter and Aguilar in this Q&A session.

Chinese $150 Linux mini-PC races OLPC to market
I can see myself buying a sub 200 buck computer. I would give it to the kids as a web and chat box. Would work great and they would love having another machine available.
"A Chinese company is touting an inexpensive Linux-based computer as a way to close the "digital divide." YellowSheepRiver's $150 "Municator" appears to be available now, with a three-month leadtime, suggesting it could reach market well ahead of MIT's $100 "One Laptop Per Child" (OLPC) device."

Writing device drivers in Linux: A brief tutorial
Learn the basics of writing a Linux device driver.
"The kernel offers several subroutines or functions in user space, which allow the end-user application programmer to interact with the hardware. Usually, in UNIX or Linux systems, this dialogue is performed through functions or subroutines in order to read and write files. The reason for this is that in Unix devices are seen, from the point of view of the user, as files."

Building an Asterisk Test Lab, Part 1
Asterisk and VOIP is way cool. This article provides clear instructions on how you can play with it.
"Deploying a new Asterisk PBX is not a trivial task, so the wise admin first sets up a test lab. This two-part sub-series will show you how to be up and running in an hour, and how to spend little or no money in the process. You should have knowledge of basic networking and Linux system administration."

How to configure a load-balanced LAMP cluster
This is an answer to the question how do we scale it even bigger.
"A LAMP cluster is not the Beowulf kind of cluster that uses specialized message-passing software to tackle a computation-intensive task. It does not cover high availability features, such as automatic failover. Rather, it is a load-sharing cluster that distributes Web requests among multiple Web and database servers while appearing to be a single server."

Mac Backup Software Harmful
Interesting article about an aspect of backing up our Macs that most people overlook.
"In this article, I will investigate commonly used GUI backup/cloning tools for Mac OS X. The tools vary widely with respect to their feature set; the features are irrelevant here. I will concentrate purely on the underlying functionality of copying files. A backup tool needs to be able to copy files faithfully for a successful restore in case desaster has struck. The surprising conclusion of my investigation is that almost all Macintosh Backup tools fail at their most basic task, the faithful copying of files."

Linux Performance Tuning
Interesting take on the issue of tuning a system for a specific purpose.
"This is probably the first thing you want to know. When a distribution is packaged and delivered to clients, it is designed to be fully compatible with most of the computers available in the market. This is a very heterogeneous set of hardware (hard disks, video cards, network cards, etc.). So distribution vendors like Red Hat, SuSe, Mandriva and the rest of them choose some conservative configuration options to assure a successful installation. "

How To Set Up A Load-Balanced MySQL Cluster
This tutorial shows how to configure a MySQL 5 cluster with three nodes: two storage nodes and one management node. This cluster is load-balanced by a high-availability load balancer that in fact has two nodes that use the Ultra Monkey package which provides heartbeat (for checking if the other node is still alive) and ldirectord (to split up the requests to the nodes of the MySQL cluster).

Interview With Andrey Savochkin, OpenVZ
Andrey Savochkin leads the development of the kernel portion of OpenVZ, an operating system-level server virtualization solution. In an interview on KernelTrap, Andrey offers a thorough explanation of what virtualization is and how it works. He also discusses the differences between hardware-level and operating system-level virtualization, going on to compare OpenVZ to VServer, Xen and User Mode Linux.

Chip Interconnects: When 133 MBps is Too Slow
It's all very nice to have incredibly fast processors, ludicrous amounts of disk space, and so much RAM that a comparable amount of magnetic core would outweigh the planet. However, if you can't move data from the CPU to memory or from memory to your disk controller, a blown-out system doesn't do you a lot of good.
