The Tao of Linux

I recently read this: The time of beginning is one of the most precious times of all. It can be very exciting and full of wonderful growth. The first thing to do is to make up your mind that you are going to go the distance.

But commitment needs something else in order to be perpetuated. It needs discipline. more>>

Bash: Redirecting Input from Multiple Files

Recently I needed to create a script that processed two input files. By processed I mean that the script needed to get a line from one file, then get a line from the second file, and then do something with them. Sounds easy enough, but it's not that easy unless you know about some of bash's extended redirection capabilities. more>>

Keeping the Kernel Klean

Operating systems drive devices. Linux is driven by open-source imperatives. So, naturally, Linux's kernel developers have a problem with closed-source kernel modules. And, just as naturally, they've hacked up a statement they hope will discourage the closed and encourage the open. more>>

Discovery - VSTi Analog Synthesis For Linux

Years ago one of Linux's finest audio software developers suggested that I should keep a watchful eye on the Windows/Mac music software scene. I took that suggestion to heart and joined a variety of Windows/Mac-centric lists and forums. I've been able to run many Windows music programs under the Wine emulator, so my participation has gone beyond mere lurking. more>>

Why eBay Should Open-Source Skype

eBay is not going through the happiest of times. Not only has it found it necessary to make 1000 people – 10% of its workforce – redundant, it has had to own up to a serious breach of trust with its Internet telephony program, Skype. more>>

MySQL Founding Father Sails Into the Sunset

It's commonplace, perhaps even de rigueur, for company executives to say their goodbyes when someone snatches up their firm mdash indeed, if we sold our share for eleventy-billion dollars, we'd probably be inclined to take a long vacation too. This wasn't so, however, for MySQL, where the company execs kept right on going post-sale — at least until recently. more>>

Bash Extended Globbing

Wildcards in bash are referred to as pathname expansion. Pathname expansion is also sometimes referred to as globbing. Pathname expansion "expands" the "*", "?", and "[...]" syntaxes when you type them as part of a command, for example: $ ls *.jpg # List all JPEG files $ ls ?.jpg # List J more>>

Clickjacking! Noooooooooo!

As if you didn't have enough to worry about, with the stock market crashing and all your savings going south . . . U.S. CERT issued a warning about a new browser exploit called "clickjacking". Worst of all, it even affects Linux browsers. Yikes! Jeremiah Grossman, founder and CTO of WhiteHat Security, U.S. CERT said, "Clickjacking gives an attacker the ability to trick a user into clicking on something only barely or momentarily noticeable. Therefore, if a user clicks on a Web page, they may actually be clicking on content from another page." more>>

LinuxWorld Sheds Its Conference Cocoon

The annual LinuxWorld conference is always a blast and a half for those who attend, especially the crew here at Linux Journal. Sadly, those halcyon days are over, as the LinuxWorld Conference and Expo is no more. Weep not, however, as in its place has appeared a new event, the freshly-christened OpenSource World. more>>

Compiz Killed My Video Card

Having recently installed a new version of Linux I thought I'd see how progress on Compiz, the compositing window manager, was going. I tried it first on a system with an ATI video card and was met with a wonderful blank screen. Since I really didn't want to spend a bunch of time trying to figure out what was going on I just put things back to normal and got X working again. more>>

Beware What is Hiding in Your Laptop – And Who Wants to Look at It

As many readers will likely know, the U.S. Department of Homeland Security — for whom we're sure we could find many a fitting and unflattering nickname, if it wouldn't land us a all-expenses-paid visit to Gitmo — recently released guidelines for the U.S. Customs Service giving agents carte blanche to search and seize travelers' laptops without probable cause, including U.S. citizens, who once upon a time were protected from such things by the Fourth Amendment. After much — well-deserved — outrage, someone is finally doing something about it, in the persons of Senators Russ Feingold & Maria Cantwell, who introduced legislation last week to put the brakes on DHS's searchmobile. more>>

Stallman vs. Clouds

I respect Richard Stallman for the same reason I respect gravity. The man is a force of nature. He is like the iron core of the Earth: fixed, central, essential. So, when I read a story like "Cloud computing is a trap, warns GNU founder Richard Stallman", which ran in the Guardian last week, I take notice. And I'm not alone. A search on Google for stallman "cloud computing" brings up 142,000 results. more>>

Examining the Compilation Process. Part 1.

This article, and the one to follow, are based on a Software Development class I taught a few years ago. The students in this class were non-programmers who had been hired to receive bug reports for a compiler product. As Analysts, they had to understand the software compilation process in some detail, even though some of them had never written a single line of code. more>>
