Amateur Radio Articles and Newsletter
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:
An Amateur Radio Survival Guide for Linux Users, written by Dan Smith.
Rolling Your Own with Digital Amateur Radio, written by Gary L. Robinson, focusing on FLDigi.
Xastir, written by Curtis E. Mills, Steve Stroh and Laura Shaffer Mills. Xastir is the Open Source APRS client software.
My personal thanks to each of these authors, as well as those who submitted articles for consideration. We had a very small window of opportunity and I am just thrilled with the participation. I hope to give you a little more lead time next time.
And speaking of next time, if you are a Linux Journal subscriber, you might have noticed a new link in the enewsletters. Specifically: Linux Journal Hamshack -- When all else fails — amateur radio, the original Open-Source project. Sent monthly. If you are as excited by this as I am, great, because there is one small, logistical issue that needs to be overcome...I have not got the first clue as to what our content will be, what we will highlight or when the first one will go out (I would like think I can do it for the end of February).
So, here is your chance! Get in on the ground floor. Put forward your comments! Please! Otherwise I might have to give up radio for...um...working on a newsletter!
But seriously. This is a great opportunity to share the wealth and promote the hobby and what we are doing with Open Source. So speak up, send me your ideas and let's see if we can make this the best darned source of information for both the communities! So tell your friends! Tell your clubs! And I will see what I can do about getting the first issue into your hands soonest!
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
