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>>

Rebuilding a Laptop Battery

When your laptop battery is about to give up the ghost, you are probably thinking of the typical three alternatives. The most obvious, of course, is "wow, what a great justification for buying a new laptop". With laptop prices falling and no such luck with battery prices, this almost makes sense. But, most of us will probably just bite the bullet and buy a new battery. more>>

A Disturbing Trend

"Lawyers in the Windows Vista Capable lawsuit against Microsoft want a federal judge to force the company to use Windows Update to notify potential class members of the suit, according to court documents." This is the opening paragraph in an article in ComputerWorld. A number of people, including myself think this is a bad idea. more>>

GIMPs Are Popping Out All Over the Place

It was just days ago that we learned that a UCLA sysadmin has discovered the largest known prime number — we'll spare a visual, as it's 13 million digits long — and possibly won $100,000 being offered by the Electronic Frontier Foundation as part of the Great Internet Mersenne Prime Search (GIMPS). Now today comes the release of version 2.6 of the GNU Image Manipulation Program (GIMP) — the follow-up to the 2.4 series, first released last October. more>>

Bash Parameter Expansion

If you use bash you already know what Parameter Expansion is, although you may have used it without knowing its name. Anytime you use a dollar sign followed by a variable name you're doing what bash calls Parameter expansion, eg echo $a or a=$b. But parameter expansion has numerous other forms which allow you to expand a parameter and modify the value or substitute other values in the expansion process. more>>

Linux Foundation Offers Up a Conference For Us All

There are plenty of Linux & Open Source conferences each year for the enthused enthusiast to choose from — LinuxWorld, OSCON, Linux.conf.au to name just a few — but curiously, nothing open to the average user from the bastion of Linux advocacy, the Linux Foundation. That is until now, as the LF has recently announced it will be sponsoring an open-attendance conference of it's own starting next year. more>>
