Fresh from the Labs
This clever little script runs on anything that has a Net connection and Perl. It grabs MP3s from a MySpace page and saves them locally. Like youtube-dl, this is not new, but it automates a number of things and does it locally from your hard drive without weird requirements. The best part is that it grabs all the songs and saves them in the format of [band] - [song title].mp3 automatically. Like youtube-dl, simply save the project file to your hard drive and flag it as executable, like so:
$ chmod u+x getmsp3
Now, simply run the script and enter the URL of the band you want after the command:
$ ./getmsmp3 http://www.myspace.com/soundskp
Of course, we can't encourage you to download illegally, so I've provided you with the URL of our own band, which you're welcome to download (slightly redundant though, as we've provided the option to download our files anyway).
Here's a project I'm dying to see the outcome of—a free (as in beer) speed camera warning system designed to run across a large range of mobile phones and GPS devices. FoxyTag is a collaborative system designed to encourage users to share speed camera data—the more users and feedback, the more reliable the system becomes. The system doesn't merely assume a speed camera is in one place either. Users have the options to report a permanent camera or the installation or removal of a mobile camera.
However, Michel Deriaz, the project's leader at Geneva University, isn't trying to promote speeding or unsafe driving. According to FoxyTag's Web site:
FoxyTag motivates neither speeding nor any other risky behavior, but allows drivers to concentrate on the road instead of having their eyes fixed on the speedometer, by fear of being flashed. We observe that drivers tend to brake suddenly when they see a speed camera (even if they are not speeding), which can provoke traffic jams or even accidents (chain collisions or slidings, like in this video [see the Web site for the link]). FoxyTag signals in advance the presence of speed cameras, so that drivers have enough time to check their speed and adapt it if necessary.
As for mobile phones, any Java mobile phone with MIDP 2.0, CLDC 1.1 and Bluetooth should be compatible. For GPS systems, any Bluetooth GPS should be compatible (including GPS modules of some navigation systems), and Michel recommends a Sirf III GPS. Unfortunately, I have neither. Hopefully, we can rustle up the needed hardware and cover this project further. I'd love to see the results of this one.

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
