Current_Issue.tar.gz - Not Even the Droid X is Big Enough for My Desk
Some of you may argue that all desktops eventually will be on tiny screens in your pockets. To be honest, however, I like my 26" screen, and my pockets aren't nearly big enough to hold it. So, although the embedded market certainly is important, this month we're focusing on the desktop—or laptop, if that's how you roll.
Charles Olsen gives a glimpse at GNOME 3, which isn't quite ready yet, but it offers some significant changes you might want to read about. Following his article, Shawn Powers (hey, that's me!) gives an overview of the other desktop environments—possibly some you've never heard of, but many you might want to try. Sometimes you want a faster desktop, and sometimes you just want to be different from the crowd. Both are reasons to check out the available options.
Having a desktop is only the start, of course. The real work is what you do while using that desktop. Stuart Jarvis helps keep things organized with Nepomuk. Most operating systems index files for quicker searching, but Nepomuk goes one step further and integrates the process into KDE. Although I still don't suggest saving everything to your desktop folder, if that's how you do things, Nepomuk might keep you organized despite yourself. If organization is something you prefer to do manually, that's fine as well. One frustration with that scenario, however, is when you move from computer to computer. Rather than organize each computer you use, why not just take your desktop with you? Rick Rogers shows how to create your own portable Linux desktop you can take with you wherever you go.
This month, we've included plenty of useful productivity information as well. Adam Pigg shows how to use the KOffice database tool, Kexi. Databases may not be the most exciting thing you'll deal with in a day, but they often pay the bills. Rather than using a separate proprietary database format, Kexi relies on SQLite for its underlying database program. That means any program able to deal with SQLite can deal with Kexi databases. It's great to see a program support standards, and Adam explains the ins and outs of using Kexi.
Bill Childers has his head in the clouds again this month and shows off the free 55-minute trial of Amazon's EC2 available for Ubuntu 10.10 users. Granted, 55 minutes isn't very long, but it's enough to give you a taste of the cloud with no commitment. If you discover you like EC2, but don't want to pay the monthly bill, be sure to read Bill's article. He has a solution for that as well. What he doesn't have a solution for, however, is the argument he and Kyle Rankin have about tablet computing. Whether you think tablets are the next logical step to a Star Trek world, or just laptops that really could use keyboards, Bill and Kyle both have good points. Perhaps I'll have to get a tablet myself—you know, for research.
We also have our regular lineup of columns, like Reuven Lerner's HTML5 discussion and Dave Taylor's help in dealing with spaces in filenames. Kyle Rankin shows how to get pop-up notifications in your terminal windows, and John Knight explores cool new programs that are fresh from the labs.
Additionally, we have a review by yours truly of the Giada N20, a sleek little ION2-based Nettop, and Mike Diehl shows off Jolicloud. We've also got info on Opengear's new cellular router and a book on making LEGO guns. It's truly a fun issue. So, whether you think desktop computing is on its way out, or if you have a wall of 30" monitors you refuse to give up, this issue has something for you. As for me, I'm going to keep my phone in my pocket and my 26" monitor on my desk. Even with my SCOTTEVEST jacket, toting around a giant monitor doesn't sound like fun. I'll leave that chore for Bill and his tablet computer.
Shawn Powers is the Associate Editor for Linux Journal. He's also the Gadget Guy for LinuxJournal.com, and he has an interesting collection of vintage Garfield coffee mugs. Don't let his silly hairdo fool you, he's a pretty ordinary guy and can be reached via e-mail at email@example.com. Or, swing by the #linuxjournal IRC channel on Freenode.net.
Practical Task Scheduling Deployment

One of the best things about the UNIX environment (aside from being stable and efficient) is the vast array of software tools available to help you do your job. Traditionally, a UNIX tool does only one thing, but does that one thing very well. For example, grep is very easy to use and can search vast amounts of data quickly. The find tool can find a particular file or files based on all kinds of criteria. It's pretty easy to string these tools together to build even more powerful tools, such as a tool that finds all of the .log files in the /home directory and searches each one for a particular entry. This erector-set mentality allows UNIX system administrators to seem to always have the right tool for the job.
Cron traditionally has been considered another such a tool for job scheduling, but is it enough? This webinar considers that very question. The first part builds on a previous Geek Guide, Beyond Cron, and briefly describes how to know when it might be time to consider upgrading your job scheduling infrastructure. The second part presents an actual planning and implementation framework.

With all the industry talk about the benefits of Linux on Power and all the performance advantages offered by its open architecture, you may be considering a move in that direction. If you are thinking about analytics, big data and cloud computing, you would be right to evaluate Power. The idea of using commodity x86 hardware and replacing it every three years is an outdated cost model. It doesn’t consider the total cost of ownership, and it doesn’t consider the advantage of real processing power, high-availability and multithreading like a demon.
This ebook takes a look at some of the practical applications of the Linux on Power platform and ways you might bring all the performance power of this open architecture to bear for your organization. There are no smoke and mirrors here—just hard, cold, empirical evidence provided by independent sources. I also consider some innovative ways Linux on Power will be used in the future.Get the Guide
