Marcel's Linux App of the Month: Workrave
I should get something like this. I tend to get so wrapped up in whatever I am working on that I forget about everything else and could use the reminders to take a stretch or a break.
"That's where Workrave comes into play. This handy little program sits quietly in the background as you work. Then, at some regularly programmed intervals, it pops up a gentle reminder to take a break. These breaks vary from micro breaks that last a few seconds to rest breaks lasting a few minutes, and finally to a message that it's time to log out and go home for the day. The length of each of these events is configurable and yes, it is possible to skip or postpone a break if you really, really, have to keep working."

Review of Intel based iMac
Review of the new iMac.
"To find out, we've been testing an Intel-based iMac against an iMac G5 only about a month old. The two machines look identical and sport nearly identical features. The major differences are hidden under the hood. For days, we ran a wide variety of software on the two iMacs, and performed all of the common tasks mainstream consumers do -- surfing the Web, emailing, instant messaging, word processing, using spreadsheets, editing photos, playing music, managing personal finances, playing simple games."

Running Things Periodically with Launchd
In case you did not know Macs use launchd instead of cron.
"I've mentioned a few times before in my essays that launchd simply rocks. It can slice, dice, and peel your tomatoes. As is already fairly well covered on the web, it can replace init and watchdog like processes all in one feel swoop. What hasn't gotten a lot of attention, however, are some of its other talents. In this essay, I'm going to focus on how it replaces cron. Yes, our venerable friend cron is due for replacement and launchd brings on the goodness."

Beating the IP Address Ban
The flip-side of filtering spam is persuading mis-configured e-mail relays to accept mail from your innocent little sendmail daemon. The latest article on Linux, Unix, /etc/ shows how to beat the IP Address ban.

How big can Quake II Grid?
OptimalGrid is a self-contained middleware designed for developers to create grid-enabled parallel applications without themselves becoming experts in grid or high-performance computing (article).The Linux compatible middleware now includes automatic distribution and provisioning on to Grid nodes. First release of Quake II made massively multi-player by running on a Grid. Get modified Quake II from Sourceforge to run with OptimalGrid and let the massive Grid games begin.

Install Front Row on ANY Mac w/remote!
Forum post that describes how to install Frontrow on any Mac.
"I'm an Apple PowerBook user and a friend recently e-mailed me with instructions on how to install Apple's Front Row on any Mac with Mac OS X Tiger. Watching the demo's of Front Row by Steve Jobs was interesting but it wasn't anything that I was really excited about but now that I have it on my computer, I love it. This post covers the following: "

SoC Drawer: Real-Time Resource Management
Systems-on-chips (SoCs) can support applications ranging from those that simply need to maximize throughput to those that must meet hard real-time deadlines. This article gives an in-depth look at SoC design for real-time applications. Get a review of best-effort, soft real-time, and hard real-time requirements, along with a detailed examination of how an SoC can best support traditional real-time scheduling policies and resource feasibility testing.

Lisp is for Entrepreneurs
I am really not sure what I think of the points this article makes. But as it's interesting and thought I thought I would share it with you.
"So, Yahoo acquires Viaweb and rewrites it. The end result is inferior to the original Lisp-based product. Sony acquires Naughty Dog and decides to eliminate the Lisp-based development infrastructure. The end result is an inferior game development environment. Sure, there were probably a lot of reasons for these decisions by Yahoo and Sony (probably none of which had anything to do with productivity or technical excellence - large companies have other drivers which have more importance than these two); however, the end result for both companies has been something inferior to what they originally acquired.

Graphical passwords for better security
Interesting idea for login security. One thought I had was that if the user can provide the photo, then in many cases the click points may be easily guess-able.
"One solution works by picking 'click points' on an image previously selected by the user. And another one, designed to avoid 'shoulder surfing,' works by clicking on random icons located inside a collection of other icons chosen by the user."

The Switch. A Boy and a Powerbook.
Yet another conversion story. I wish I could get all my friends to have the same experience.
"My motto was, 'I love the Powerbook and I love OSX. I would get one as a second computer or portable but I'm not ready to give up my Windows box. There are some things that I just can't to on a Mac.'That has changed. I'm ready to dump my dull little box, dutifully performing its dull little tasks for something different, something powerful, something better."

Life as a Linux/Unix admin in a Windows world
I have been a Linux/Unix admin for about 7 years professionally now. I actually started off as a Junior Admin at a Linux company. This experience taught me allot, but also got me spoiled. At the Linux company, you were made fun of if you used Windows. We had one machine in the building running Windows, and that was for the Exchange server which we needed for our development team. This company was writing a email client for Linux, and Solaris that would communicate 100% to exchange (yes before evolution did it, and before exchange 2000). Every desktop in the building was running some distro of Linux. So basically I never had to argue about Linux/Unix stability, ease of use, etc.

Guide for the Linksys WRT54GL
Very nice guide on doing cool things using a Linksys WRT54GL wireless broadband router.
"I recently acquired a Linksys WRT54GL wireless broadband router. The nice thing about this piece of networking gear is that it runs Linux. There is an abundance of information on the prior model (WRT54G) of this series on the Internet. In fact, there is so much information that I had over twenty tabs open in Firefox of various web sites to sort through just to get the information that I needed to hack on my new router. So I decided to write this guide to save others from information overload."

The Linux HTPC Howto
How to build a media computer using Linux.
"The purpose of the Linux HTPC Howto is to help educate people who are interested in learning about or building their own media computer (aka HTPC). The perfect HTPC solution doesn't exist and because of this there are many ways to build a HTPC and there are even more pitfalls that can make a HTPC more troublesome than helpful. This guide is designed to help both Windows and Linux users see what is involved in building a HTPC and what technologies need to be considered to make your goal a reality. The guide also takes many of the complicated details that are typically overlooked by people new to HTPC's and helps make things easier to understand."
