Running Complex Commands with sudo

If you use sudo to run commands as root, you've probably run into “permission denied” problems when only part of a pipeline or part of a command is running with root permissions.

Building on Richard Stallman's Greatest Achievement

What was Richard Stallman's greatest achievement? Some might say it's Emacs, one of the most powerful and adaptable pieces of software ever written. Others might plump for gcc, an indispensable tool used by probably millions of hackers to write yet more free software. And then there is the entire GNU project, astonishing in its ambition to create a Unix-like operating system from scratch. But for me, his single most important hack was the creation of the GNU General Public Licence. more>>

Troubleshooting Network Problems

Back when I worked in the Network Operations department at one of my previous jobs, we used to chuckle when a customer would call us reporting that “the Internet is down.” Now, I realize that there are otherwise intelligent computer users out there who don't understand why that might cause a technician to chuckle, and I'm not trying to make fun of them. more>>

KDE Hopes for a Flood of Ideas

A project that has no goals — no bugs to fix, no features to implement — has only stagnation to look forward to. The best prevention for this kind of stagnation is an active community of users who are quick to share what they want with the developers — even if there is the occasional users vs. devs feature stalemate. The KDE Project has no shortage of community-contributed ideas, and to keep the concepts flowing freely, the powers-that-be have implemented a new feature of their own: A designated section of the KDE Community Forums christened The "Brainstorm" Forum. more>>

Slice and Dice PDF

Firefox Tops 46%?

In the seemingly never-ending browser wars, monthly usage statistics are an important metric of just what is really going on on the "battlefield." For Open Source advocates, these statistics are equally if not more important, as they give a reasonably reliable overview of Open Source adoption.

Shopping on Penguins

I was pointed recently to Zappos as a near-perfect example of a company that brings the principles of open source to business. Its site is inventive and fancy (as you'd expect a clothing retailer to be), but not a triumph of design over utility. What's more, it's fast. more>>

Tux Takes A (Tasmanian) Vacation

One would be hard pressed to find a Linux user who hasn't at one point or another become acquainted with Tux, the fine-flippered fellow who serves as mascot for all things Linux. Everybody needs a break now and again, though, and so Tux has gone on sabbatical — reportedly to work as a barber — leaving the face of a very worthy cause to hold down the fort. more>>
