Linux Unwired
"The authors start up with introduction to wireless, intended for Linux geeks who are not quite up to speed on radio technologies. The concepts of waves, spectrum and radio wave behavior are explained, so later the reader can explain what a retracted radio wave is. Then the first chapter moves on to explain antenna behavior, wireless infrastructure modes and some common problem, like a hidden node in ad-hoc infrastructure. The chapter is well-written, and you're not expected to have an advanced radio degree or ARRL membership to understand the terms."

Mondo Rescue LiveCD backup: a nugget of gold
"I received an email a few weeks ago following a column I wrote on backups. The reader said, "I'm looking for a way to back up (preferably image) my current Fedora install to CD-RW. Ideally, I guess what I'm looking for is 'bare-metal' disaster recovery -- i.e., boot up from CD, enter some command(s) and have my (mostly!) working Fedora install re-imaged back to my HD." I didn't, but I suspected I could find a LiveCD for this purpose. Sure enough, Mondo Rescue does everything the man asked for. The only drawback -- if there is one -- is that it's more geared for advanced users or system admins that it is for noobies."

The Print Shop Mac OS X Edition 1.0
"Over the years, The Print Shop, a popular design and desktop-publishing package for creating greeting cards, calendars, labels, and similar projects, has come and gone. Now, thanks to its new developer, Software MacKiev, this long-missed program is back on the Mac and better than ever. The Print Shop Mac OS X Edition 1.0 is versatile, elegant, and easy to use, and it integrates seamlessly with other Mac applications, such as Apple's iPhoto, iTunes, iCal, and Address Book."

AirTunes: Where Does Apple Go Next?
"Which is why, during my conversation with Apple Vice President of Hardware Product Marketing Greg Joswiak yesterday, I was surprised with just how casual and open he was about AirTunes and where it might be headed. When I suggested that AirPort Express wouldn't fulfill a certain group of users' needs because you've got to use iTunes to control it rather than a hand-held remote, he didn't dispute that. In fact, he seemed to suggest that a remote control might indeed be a logical direction -- but that Apple wanted to get this first product out the door, to get the ball rolling."

Power Supply Exchange 15" Flat Panel iMac
"Carefully ease the base towards you to detach it from the body of the iMac. There will be wires attached to the base, I recommend you disconnect the majority of them to reduce the clutter. At this point you need to remove the optical drive assembly as the power supply is above it. Use your Torx-10 screwdriver for this task. In the picture below, the two screws on the far right secure the EMI shield, it also has a strip of copper tape that holds it on the optical drive. I prefer to release all screws and remove the drive assembly with the EMI shield in place, if it makes it easier for you to remove it from the optical drive simple peel the tape off and reapply when reinstalling everything."

OS X Tip: Remapping keyboard shortcuts
"On my Mac, Apple+W is the shortcut for closing a window (or tab in a tabbed application such as Safari or Firefox) while Apple+Q quits the application completely. These keys are right next to each other on the keyboard. Today, for the final time, I hit the wrong key and accidentally sent a couple of days accumulation of useful browser windows straight in to the abyss. I say for the last time because my intended IRC rant about the stupidity of setting those two keys right next to each other was cut off by Richard Soderberg, who showed me how to remap keyboard shortcuts for any application in OS X. #"

Version Control with Subversion: Basic Concepts
"Subversion is a centralized system for sharing information. At its core is a repository, which is a central store of data. The repository stores information in the form of a filesystem tree—a typical hierarchy of files and directories. Any number of clients connect to the repository, and then read or write to these files. By writing data, a client makes the information available to others; by reading data, the client receives information from others. "

Wireless Attacks and Penetration Testing part 2
"Our first task is to figure out how to gain access to the WEP-protected wireless network. Using AirSnort, named after the venerable intrusion detection system Snort, you can passively monitor transmissions across a wireless network and, from that monitoring, derive the encryption key for a WEP-protected network once you have an adequate base of packets."

Console surfing with Lynx
"Your first use of Lynx may give you a bit of a shock, as it is a whole 'nother way of surfing: you use your fingertips and type instead of moving a mouse. Here are a few basic commands you'll want to learn right away, demonstrated by using the Linux.com home page. Get started on this magical mystery tour by entering lynx www.linux.com in your console window."

Assembly Language Techniques for Solaris
"This paper discusses assembly language techniques for the Solaris Operating System running on the x86 architecture. My focus is to help others not just figure out how to integrate assembly language into their projects, but also help demonstrate that assembly language is not always the answer for better performance. I will not be covering the x86 instruction set or how to write assembly code. There are many books on the market that cover those topics extensively."

Linux Lite: Cobind and the Simpler Life
"The target user of Cobind is the Linux newcomer, particularly one moving away from Windows. This is a computer user of some sophistication, but not looking to make a career of using a new operating system. He or she owns, at home, a Windows-based machine that no longer has enough horsepower to run the latest applications. He or she is very, very tired of Microsoft viruses. Because this target user audience is hoping to get one more cycle of use from an older computer, we can assume that no one wants to spend any more money than necessary. Cobind goes for just $10"

New Detective in Bioinformatics
"How, for example, does the DNA in one cell — a single fertilized egg — give rise to the 10 trillion cells that create a fully-formed human being? How do cells in a fully-formed person sustain themselves? On this new biological frontier, Craig Benham, a mathematical biologist and founding associate director of the UC Davis Genome Center, is working to uncover one of the secrets — using a 38-node cluster of Apple Xserve G5 systems and Mac OS X in a single virtual computing resource."

Control iTunes from anywhere
"A long time ago I wrote Apache::iTunes so I could control my iTunes through a web browser. Today I found webRemote, a mini-webserver with a Mac configuration interface which does the same thing. webRemote is speedy, although I have not dusted off Apache::iTunes to see if it is any faster on my new hardware. webRemote comes with several skins and looks like better designed versions of the ugly template I used in my module."

Small-scale school enthuses students
"There is no bell. The class roll is checked off from a laptop computer. Every student has access to a gleaming Apple Mac computer. Classes last 90 minutes instead of the usual 45 minutes. They start and finish later. There are fewer holidays. There are no more than 22 students in a classroom. And the teachers know the name of every single pupil."
