Focus: Science and Engineering
I must say this issue ended up being more science than engineering, but perhaps that is not surprising considering my scientific leanings. I thought about dropping the word “engineering”, but since the S&E focus has become traditional, I decided to keep the word and wave my hands a bit. Our main feature article is from Dr. Steve Mann of wearable computer fame, and he has certainly pulled off a slick piece of engineering in his videophone watch shown on our cover. Dr. Mann is an accomplished photographer as well as inventor, and he gets credit for the picture of the watch on the cover and the one with his article. Dr. Mann certainly lives on the leading edge of this technology, and we are happy to have another article from him to keep us abreast of developments in wearable computers.
For those readers who like to watch the skies, we have a little of everything: satellite tracking, astronomy (even our French chef, Marcel, has something to say on this one), storms and lightning. Science articles can be found everywhere: in Features, Forum and Strictly On-Line—enjoy!
Linley Gwennap becomes a regular columnist for us this month with his column “Linley on Linux”, where he will keep us up to date on some of the latest happenings in the electronics market for Linux. This month, he tells us what's happening in the field of voice recognition.
Speaking of columnists, Moshe Bar will also be joining us on a regular basis to teach us about kernel issues in Kernel Korner, and next month, we'll have an all-new column on cross-platform programming written by Michael D. Crawford. Both should keep our inner penguin quite happy.

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
