HOW-TOs

Start and Control konsole with DBUS

February 2nd, 2010 by Mitch Frazier in

Some time back I wrote about creating a number of konsoles automatically using dcop. Although we were at the time well into the KDE4 era I had not yet upgraded since there were still things that weren't quite working with KDE4, most of these have now been fixed so I've upgraded some of my systems to KDE4, which means it's time to update the original code to now use dbus.

Tech Tip: Use gxmessage for Displaying GUI Messages from Scripts

January 28th, 2010 by Kris Occhipinti in

There are many dialog programs out there, Zenity, Kdialog, xdialog, etc. I love programs like these. They make it so easy to spice up a shell script with a little GUI action. Today I'm going to go look at a dialog program called gxmessage.

Tech Tip: Keep Your Monitor Awake with Caffeine

January 21st, 2010 by Kyle Flanagan in

One of my favorite new apps is a little system tray app called caffeine (and here). It's simple, yet very practical, its purpose is to inhibit a screen saver or sleep mode, which is great while watching flash videos on sites like hulu.

Tech Tip: Dereference Variable Names Inside Bash Functions

January 15th, 2010 by Mahaveer Darade in

We often read (including in the book Advanced Bash-Scripting Guide by Mendel Cooper) that if we pass variable names as parameters to functions, they will be treated as string literals and cannot be dereferenced (ie the value is not available). But this is not so, variable names can be passed as parameters to functions and they can be dereferenced to obtain the value of the variable with the given name.

Crafting Digital Media: A Book Review

February 1st, 2010 by Dave Phillips in

I don't usually write book reviews, but this one is special. My friend and colleague Daniel James has written an introduction to the world of media production with Linux, or as the subtitle describes it, "A manual for creative media on a modest budget". I'll put the spoiler right up front: This book is wonderful and is an essential read for all artistically-inclined Linux users. Read on to find out why I think so.

When Cacti Are Too Prickly

January 20th, 2010 by LJ Staff in

I'm a clock watcher. I'm a tachometer hound. I'm a speedometer freak. And, as cool as that might seem, more than anything, I love graphs. One of the problems with setting up good SNMP graphs is that not only do they require a server on which to run, but also those servers often are difficult to configure.

The Gifting Season: Linux Audio For The Holidays

January 11th, 2010 by Dave Phillips in

During the final months of 2009 Linux audio developers and users were working overtime. If you feel that you didn't get enough goodies in your holiday stocking perhaps you'll find a few more stuffers listed here as another year closes in the world of Linux sound and music software.

OpenMovieEditor And Blender: More NLE Delights

January 6th, 2010 by Dave Phillips in

We're getting close to the last stops on our tour of non-linear video editors (a.k.a. NLEs) for Linux. This week I've focused my attention on two editors, both of which surprised me in many ways.

Amateur Radio Articles and Newsletter

January 31st, 2010 by David Lane

For those that have been waiting patiently for the Amateur Radio articles from the January 2010 edition to be available on line, your wait is over! You will find a permanent link to them in the Linux Journal Virtual Ham Shack, but for your convenience, I will put them here too:

Wither the web (site)

January 26th, 2010 by David Lane

Are web sites today so complicated because they have to be or because they can be?

I am sure if you are a web site designer, you believe the former, but as an end user and part time designer, I am really beginning to wonder.

Linux.conf.au - Day One

January 18th, 2010 by Jes Fraser

LCA 2010 - Day 1

January brings with it the southern-hemisphere's summer and Linux.conf.au. This year, the conference is being held in Wellington, New Zealand thanks to the hard work and dedication of the Capital Cabal, a team of volunteer organisers lead by Susanne and Andrew Ruthven.

Ereaders...not quite the death of paper

January 4th, 2010 by David Lane

I am the proud owner of an ereader. I have had a Sony PRS-600 (Touch) for less than 24 hours. But unless something changes dramatically, I am unlikely to be an ereader user 24 hours from now. To say I am disappointed would be an understatement. For what I have paid for the unit, I almost feel taken. Before I delineate the short comings, let me tell you how I got here.

2010 - A Linux Odyssey.

December 31st, 2009 by David Lane

Here at Linux Journal, 2010 has been designated a Linux Odyssey. I was fortunate enough to be asked to lead the charge as the Guest Editor for the January issue where we took a small departure from our normal January focus and instead looked at Amateur Radio and Linux.

Happy Birthday, Linus

December 28th, 2009 by Glyn Moody

Today is the birthday of Linus. Although that's essentially a private event for him, there's an interesting historical link to the creation of the Linux kernel, too.

Does the distro matter?

December 22nd, 2009 by David Lane

I got a phone call yesterday from a recruiter wondering if I would be interested in a Linux administrator position. The first question she asked was did I have any experience with Oracle RAC and I could hear her eyes glaze over as I answered her with a brief description of what I have done with RAC. After shaking herself back to life, she asked if I had any experience with Unbreakable Linux.
