Bash: Redirecting Input from Multiple Files
October 14th, 2008 by Mitch Frazier in
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.

Bash Extended Globbing
October 8th, 2008 by Mitch Frazier in
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

Research Report: "Open Source in the Enterprise", a Review
October 2nd, 2008 by James Gray in
This is a review of a relatively new resource, called Open Source in the Enterprise (OSIE) by Bernard Golden. The report's raison d'être is to help companies to decide if open source applications are right for their enterprise, and if so, how to implement it intelligently.

Keeping the Kernel Klean
October 13th, 2008 by Doc Searls in
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.

Adios Windows 9x
September 25th, 2008 by LJ Staff in
The upcoming release of Cygwin version 1.7 will be dropping support for Windows 9x (Windows 95, Windows 98 and Windows Me). If you're lucky enough never to have to use Windows, Cygwin probably seems like a waste of effort. But, if you're not so lucky, Cygwin is what keeps you sane.

The Tao of Linux
October 15th, 2008 by Phil Hughes
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.

Clickjacking! Noooooooooo!
October 8th, 2008 by marcel
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."
Compiz Killed My Video Card
October 7th, 2008 by Mitch Frazier
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.
Stallman vs. Clouds
October 6th, 2008 by Doc Searls
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.
Rebuilding a Laptop Battery
October 5th, 2008 by Phil Hughes
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.

A Disturbing Trend
October 4th, 2008 by David Lane
"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.

There aren't many numbers that put the US national debt to shame, but here's one: 1,100,000,000,000,000. What's that? That's how many floating-point operations per second the Roadrunner supercomputer at Las Alamos can perform. That's about 100 FLOPS per dollar of US debt (unfortunately, the debt is winning the second derivative race). Read the article about Roadrunner in this month's High Performance Computing issue of LJ.
Along with that, find out how to program the Cell processor and how to use CUDA with your NVIDIA GPU. Also in this issue: Mr HandS (aka Kyle Rankin) gives us a few tips on using Compiz, Chef Marcel shows you how to get blogging off your plate quicker, Mick Bauer talks about Samba security, Dan Sawyer interviews Cory Doctrow and Doc talks about how information technology can affect democracy and fix the national debt (just kidding about that last part). That and more for your reading pleasure in this month's Linux Journal.
