Open Source Ham – Is that like free range chicken?
If you have not stopped by the #linuxjournal IRC channel yet, I would encourage you to do so. You never know who you will meet or what sort of new ideas will germinate.
For example: the other day, while having !coffee and a danish, I was chatting with our fearless Editor-in-Geek, Carlie, and she was commenting that someone had left the radio on. No, not that radio, the Amateur Radio. This got my attention as I was not aware Carlie had her ticket (she does not - I am working on her - browbeating is the term my XYL uses, but I digress). As many of you know, I too am an Amateur Radio operator - a ham. [I should note that personally, I don't like the term...it does not mean anything, but it is what most folks know us as so...]. And we started chatting.
The history of Open Source software, especially Linux and Amateur Radio, is well integrated. There are as many hackers in the Amateur Radio hobby as there are in Open Source. In fact you could call Amateur Radio the original Open Source project. A number of modern developments in Information Technology, from the radio (d'uh) to the network card can trace their way back to some home brew radio operators working in their basement. The Linux kernel has long supported the AX.25 protocol (a bastard version of X.25 used in early packet transfers via radio) and several popular programs have Open Source analogs. One of the most recent developments in Amateur Radio, the D-Star digital protocol, is a fully Open Source project and is the first in recent memory where a corporation has developed a radio system utilizing the Open Source model.
As Carlie and I were talking, we wondered if there were enough interest in the communities for articles in the Linux Journal about the projects being done in Amateur Radio. Now before you get all spun up, we are not talking about killing off the Paranoid Penguin or converting the wine cellar into a ham shack, but as Dave Phillips has tapped the world of Linux and musicians and music engineers with the occasional article, we think there is interest in the readership for the occasional Amateur article.
Now is your chance. What sort of cool project are you using in your ham shack? Based on an email I sent to the ARRL PIO reflector, there are a lot of projects out there that we could highlight, everything from making it easier for Section Managers to update their web sites to unique ways to inject messages to the radio network via web interfaces to simple radio control software and logging software.
So are you an Open Source Ham? Because, When all else fails…
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
