A developer's guide to the PowerPC architecture
PowerPC® processors are found in everything from supercomputers to game consoles and from servers to cell phones -- and they all share a common architecture. This introduction to the PowerPC application-level programming model will give you an overview of the instruction set, important registers, and other details necessary for developing reliable, high performing PowerPC applications and maintaining code compatibility among processors.

FreeBSD 5.2.1 on SPARC64
FreeBSD has a solid reputation in terms of features and performance on x86, powering sites from Hotmail to Yahoo, yet it doesn't tend to be the first (or even second) OS that comes to mind with many people when thinking of Solaris alternatives for the SPARC platform. Tony Bourke tests FreeBSD 5.2.1 on his SPARC machine.

Linux Kernel 2.6: Embedded Computing, Part II
"On the complete opposite end of the field, for the first time the kernel includes support that allows a Linux-powered machine to be a USB device rather than a USB host. This would allow, for example, your Linux-powered PDA to be plugged into your PC and to have both ends of the line speaking the proper protocol. Much of this support is new, but this is an essential direction for Linux to move into for embedded devices."

Quicksilver Is Seriously Cool
"Quicksilver is an awesome application that works with all of your favorite programs, such as iTunes, Address Book, Safari, Mail, and many more. It also substitutes and aids the Finder, offers a 10 item clipboard memory, and a shelf for storing random tidbits. By hitting command and space, while in any application, brings up the Quicksilver command window, bezel, or menu (depending on your preference)."

AppleScript: The Definitive Guide
"This book is designed to be an explanatory manual and an AppleScript reference suitable for all levels of users from novices to experienced scripters. It begins by describing potential uses for AppleScript, progresses to AppleScript’s structure and commands, and ends with a chapter on writing AppleScript applications. The book focuses solely on AppleScript for Mac OS X, though OS 9 users may find it useful."

EmPOWERing the Linux developer
Recognized as a high-performance, reliable, and serviceable enterprise platform, the 64-bit POWER architecture offers new choices to UNIX and Linux application developers. This article reviews the different POWER Linux distributions, the kernal optimization for POWER, GNU Compiler Collection and the tools needed to get started with enterprise Linux on POWER-based systems.

IP Spoofing: Understanding the basics
"IP Spoofing thus, can be said to be the process by which you change or rather spoof your IP Address, so as to fool the target system into believing that your identity is not the one, which is actually yours, but make it believe that you actually are the computer having the spoofed address. Let us take a real life example to understand better. "

Building a new box from scratch
"This is the Antec Performance II SX1040BII. It comes with an Antec 400W power supply. This is a very nice case, and made of aluminum. The case is very well put together and has lots of cooling power. By default, it comes with four fans (two in the PSU, two in the case) and room for two more optional case fans. I like this case quite a bit. Just look at the number of pictures..."

Clustering and Load Balancing in Tomcat 5
"The Tomcat 5 server comes with a rules-based load balancer application. Two simple custom load balancing rules (extending the rules API) were written based on round-robin and random algorithms to redirect incoming web requests. Performance benchmarks for the sample web application running in the cluster environment are presented. The load testing tool JMeter was used to simulate multiple web users to study the load-balancing mechanism."

The iNoteBook
"The iNoteBook started out as a non-working iBook 500 with no display, hard disk, memory, or battery, and the DVD drive bay was on the fritz. In other words, a perfect candidate for a hack! I was able to get the machine to boot with some new memory and a little work on the DVD drive, so I began to think about what kind of machine I wanted to make. "

Setting Up Apple Remote Desktop
"If you work in an environment where you need to manage a large number of Macs (such as in a classroom), you might want to take a look at Apple's Remote Desktop. Using this pricy but effective software, you can easily control and manage all of the Macs on the network. Windows users probably take this functionality for granted, because that platform includes Remote Desktop Connection."

Firewall Failover with pfsync and CARP
"The two main components provided by OpenBSD are CARP (the Common Address Redundancy Protocol), which allows a backup host to assume the identity of the primary, and pfsync, which ensures that firewall states are synchronised so that the backup can take over exactly where the master left off and no connections will be lost."

Basic Slackware Security
"This article is meant to be a crash course in Slackware security. It will detail some basic steps that should be taken before you consider Slackware to be fully installed. Again, these are basic steps - more services will require more configuration. And note that you'll have to be root to perform the configuration tasks in this article. On to the install. "

PHP and Apache 2.0
"It seems that one of the key features of Apache 2 is the new threaded worker module which uses threads to serve more requests more efficiently than 1.3's multi-process based server. While the core Zend engine of PHP is thread-safe many of the critical libraries that PHP relies on for its advanced functionality (image processing, database connectivity and so forth) are not, and are unlikely to become so any time in the future. In a threaded environment PHP is likely to suffer from all kinds of unpredictable bugs."
