Output Like a Pro with iPhoto 5
"In my previous iPhoto 5 article, I discussed how easy it is to upload and manage RAW files. This eliminates a huge barrier. RAW photography used to mean "more pain than fun." Instead of playing with my pictures right after a shoot in iPhoto, I found myself "working" in Camera Raw. iPhoto 5 has changed that. Now anyone can input like a pro... and love it."

The social structure of open source development
"Andreas Brand is a sociologist researching ways of recruiting and organising teams of volunteers on the Internet. He has been studying KDE as an example of an open source project based upon collaboration without hierarchies. As part of his work he has conducted interviews with KDE developers, participated in several open source conferences, analysed the KDE home page, and distributed a questionnaire among volunteers. We asked him about his thoughts on the KDE development model."

Linux Client Migration Cookbook
"The Cookbook covers a lot of ground, and provides an extensive list of open source alternatives for a wide variety of common Windows applications. The Cookbook also deals with infrastructure considerations, particularly in situations where Windows and Linux clients need to be able to utilize the same network services. The Cookbook explores technologies that simplify cross-platform domain authentication, file sharing, and network printer access."

Why Apple Makes a One Buttoned Mouse
"There are a lot of misconceptions about the Macintosh, but one misconception that has persisted is the myth that Mac’s are incapable of using multi-button mice. And those who know this myth is false still complain about Apple not shipping computers with two button mice. Gear Live cub reporter XIcarus wanted to share a bit of background on what many believe to be Apple’s stubborness to conform."

What powers your university, Solaris or Linux?
"University semester-end examinations over, I have quite a lot of time in my hands till the next semester begins. Time for some research of my own! I decided to check the type of operating system (OS) and web-server software being used at the Times 100 Top Universities in the World. So, I downloaded the TIMES World University Rankings, dated November 5th 2004, tracked down the universities in NetCraft and analyzed the data that I have carefully collected.

Some Linux apps are small wonders
"While it's easy to sing the praises of big applications like OpenOffice.org or the GIMP (and rightly so), the heavyweights of the open source world cast a long shadow over a host of much smaller, lesser-known apps that may do just what you need. One of the original philosophies behind Unix was that a program should do one thing and do it well. Here are a few programs that embody that philosophy."

Gnoppix 0.9.9b1
"This LiveCD will not take you directly to the Gnome Desktop environment, it will ask you some questions and you will be prompted with some ncurses dialog windows that will ask you about the language you want to use and your keyboard layout. After that and some hardware autodetection the boot of the graphical environment will boot. The look & feel is the Ubuntu's one, same wallpaper as background too. "
