Whirlwind Wheelchair empowers the disabled with open source
by Sandra Wills
Getting from point A to point B is a need that we all have, but what if you're in a third-world country and require a wheelchair?
Painless dual-booting with Red Hat® Enterprise Linux® 5 and a MacBookPro
by Noah Gift
I know there are many OS X users curious about running Linux on their Mac hardware, but are overwhelmed with the configuration options. There are also many Linux users who want to work on one machine and would like to dual-boot OS X and Red Hat Enterprise Linux 5.
What's new in SELinux for Red Hat Enterprise Linux 5?
by Dan Walsh
For many people, security is a subject that they only think about after something bad happens. Like buying a home alarm system after your home has been burgled. Why? One reason is denial--after all, bad things always happen to someone else. Additional reasons may be the perception that security, especially in software, is too hard. People either don't use it, or use it incorrectly.
Risk Report: Two years of Red Hat Enterprise Linux 4
by Mark Cox
Red Hat Enterprise Linux 4 was released on February 15, 2005. This report takes a look at the state of security for the first two years from release. We look at key metrics, specific vulnerabilities, and the most common ways users were affected by security issues. We will show some best practices that could have been used to minimize the impact of the issues, and also take a look at how the included security innovations helped.
When you gotta go, you gotta go
by Mike McGrath
Normally when Linux types talk about patents, we tend to talk about software patents. This story, however, is about more traditional patents. It's a dark tale involving a man, a portable waste disposal device, and murder. It just so happens, I was there.
Squid in five minutes
by Noah Gift
Why Squid? Why only five minutes? There are many great tools that Squid has to offer, but when I need to redirect http traffic to a caching server for performance increases or security, Squid's my pick. Squid has built in proxy and caching tools that are simple, yet effective.
Summit 2007
The calm before the storm
by an editor
Everyone's assembled in San Diego, CA for the third-annual Red Hat Summit, which begins today. Though the guests arrived just last night, our staff and speakers have been preparing for the event for months. Now that it's begun, it doesn't get any less exciting. Partners to meet. Users to greet. Speakers to speak. Great food and drink. Late nights. Good times.
Day zero, blog one
by Jeff Mackanic
Arrived in sunny San Diego earlier today and wow it is certainly beautiful. The hotel is right on the bay and there are sailboats docked behind it.
Day zero, blog two
by Kris Bowen
Summit staff log--Summit date 5/9, 1:00 a.m.
This is my take on a Star Trek captain's log. I know, not very funny. But give me a break?it's one in the morning, and I've been up for a long time. (The ironic part is I'm not even a
Trekkie.)
Day one, link wrap
by an editor
Lots of news coming out of the first day of the Summit. We've been keeping track, and here's the day one round-up.
Good for the body and mind
by Tim Hyer
Day one at the Summit started bright and early for me. The sun rises early in San Diego, and brings the kind of weather that makes you want to get out of bed and start the day. So I headed to the gym. Strolling into the workout facility just after 6 a.m., I figured I'd have first dibs on my choice of machines. Much to my surprise, the place was already humming with activity...
Introducing RHX: An open source marketplace
by Julie Bryce
Red Hat released Red Hat® Exchange at the 2007 Red Hat Summit. RHX takes another step toward providing users the value of open source across their entire business. With RHX, you can shop a marketplace of open source applications?all are guaranteed to run on Red Hat Enterprise Linux, delivered through Red Hat® Network, and supported by Red Hat.
Liberation Fonts
by an editor
One of the exciting announcements out of yesterday's Summit coverage was a gift given by Red Hat to the community. A new set of fonts, free to use and free to distribute. The Liberation fonts.
Day two, link wrap
by an editor
Whew. Two days down, one to go. Here's a list of all the cool stuff being written about the Summit today (and a few items that we missed yesterday).
Alan Dechert of the Open Voting Consortium
by Julie Bryce
We got the chance to chat a bit with Alan Dechert during the 2007 Red Hat Summit. We asked him some questions; he gave us some answers.
Why our voting system is corrupt and what we can do to fix it
(Hint: Think open.)
by Julie Bryce
I like new words. Today's new word is "Systers". Here, I'll use it in a sentence: There are plenty of Systers at the Red Hat Summit this year. If you haven't caught on by now, systers are female system administrators. And though I thought them a rarity, the diversity in both gender and ethnicity at the Summit this year has been the best in three years.
Day three, link wrap
by an editor
Link wrap--think shrink wrap--is a packaged-up mix of articles, pictures, and general stuff from this year's Red Hat Summit. Here's the last daily group (though we may post a follow-up early next week if we see more info out there). Thanks for reading along, and we hope everyone at the San Diego event had a lovely time. Hope to see you all next year!
That's a wrap
by an editor
Just a few more things that have crossed our radar in the few days post-Summit...
- Watch the Summit highlight videos and see keynotes by Matthew Szulik, Brian Stevens, Matt Mattox, and David Pakman.
- Read Chris Blizzard's Summit summary .
- Awards and Moglen mark Red Hat Summit finale by Joe Barr (Linux.com)
- Red Hat still has sway by Phil Hochmuth (Network World)
- EMC Delivers World Class Support for Red Hat Enterprise Linux
The Summit ends. And not with a whimper.
by Jonathan Opp
Friday, final day of the Summit. My morning starts in Eben Moglen's session on GPLv3. You'll remember Moglen gave an unforgettable keynote address last year. This year his individual sessions give attendees the chance to ask questions directly. It's no surprise that Moglen is as articulate and passionate responding to questions as he is with his prepared comments. His wit is sharp. And when he turns a phrase just right, he pauses and lets it hang in the air for a moment. The audience laughs. He deadpans. It's brilliant.

The lowdown on GPL 3 (with Eben Moglen)
by Julie Bryce
With the help of Red Hat deputy counsel Mark Webbink, we tracked down Eben Moglen at the Red Hat Summit earlier this month. We asked him about GPL 3, why he's leaving the Free Software Foundation (FSF), and learned what's next for the pioneering legal scholar.

Open source in education? Now that's using your Moodle.
by Julie Bryce
The line between learning in the classroom and learning independently has been forever blurred. Thanks to the resources of the web, kids as young as nine can learn the way college students do. Learn more about the open source content management system, Moodle.

Inside One Laptop per Child, Episode 02
by Julie Bryce
Episode 02 of this series documenting the One Laptop per Child project focuses on the activities built for the laptop. Activities, not applications, since the machine is designed for children and applications is a decidedly adult word.

Eben Moglen on Microsoft's 'be very afraid tour'
by an editor
Perhaps you've seen the recent headlines . Or perhaps you saw them last summer...or the summer before that. Free and open source software infringes our patents, they say. Open source users may have to pay royalties, they say. Is it true? Is open source really under that kind of threat?

Nokia Internet Tablet: Sysadmin's friend?
by Matthew Schick
A bane of the system administrator's (SA) job is on-call work. You either end up lugging a laptop or making a dash for the nearest machine when things go wrong. It would be nice to have something that was a bit more portable but had enough tools to fix most issues. The Nokia Internet Tablets ( N770 and N800) offer a mostly complete Linux environment and are quite portable, but can they really offer SA's more freedom?
The Linux Programmer's Toolbox
by Christopher Smith
The Linux Programmers Toolbox provides a thorough introduction on the essential C and C++ development tools packaged with common modern Linux distributions. It is predominantly geared towards programmers who are new to the Linux platform, but power users and systems engineers perk up?there is enough cross-discipline information to absolutely warrant a closer look.
Red Hat Enterprise Linux 5 Administration Unleashed
by Neil Horman
I'm a 32-year-old software engineer working for Red Hat. The last time I did a book review, I was reading The Great Gatsby when I really wanted to focus on the upcoming seventh grade spring dance. Fortunately I can now read (and review) books that I find interesting. Red Hat Enterprise Linux 5 Administration Unleashed by Tammy Fox fits the bill. It is, as its name implies, an admin guide and reference guide.
Book review: Wikinomics
by Jeff Mackanic
I feel like I should have enjoyed this book more. After all, it has gotten lots of press and is very popular...

The open palette: Creating grungy Gimp brushes using Inkscape
by Mairin Duffy
Welcome to the second installation of The open palette. Last time, we focused on creating orbs and 3D text using Inkscape's new blur filter. This month, we'll be focusing on creating brushes for the Gimp using Inkscape.
Thinking Design: A pencil, a ruler, and a cup of coffee (Part 2)
by David Burney
In a previous article I explained why the title above has meaning for me. I'd like to dig a bit deeper, so you may want to read that article first if you missed it. If you take the client's perspective in the above quote to its logical ending, I think you can make the argument that everyone is a designer. Most of us don't think that way. But, after 30+ years in the industry, I do.
Building the XO: Porting a PyGTK game to Sugar (part I)
by John (J5) Palmieri
Welcome to this tutorial series on porting a PyGTK game to the OLPC's Sugar environment. While we will be concentrating on a game called Block Party, the lessons taught here can be used as a guide to create or port any number of applications. Games are just more fun to learn with.
Building the XO: Porting a PyGTK game to Sugar (Part II)
by John (J5) Palmieri
In the last lesson we learned about what made Block Party tick. In this lesson, we will turn the same PyGtk codebase into a Sugar activity with only minimal modification of the core code. As always, the code for this lesson can be found
here.
For this lesson you will need a computer with the latest version of the Sugar environment running on it. This can either be from
sugar-jhbuild or any build after or including
build 303 running in an emulated environment like qemu, from the LiveCD or on the laptop itself.
How to write really good documentation: Donald Knuth was wrong
by Brian Forte
While it's true we still need 'better documentation of programs' it isn't true, or it is no longer true, 'that we can best achieve this by considering programs to be works of literature.' Huh?
