Smarter Than Phones
The phone business is changing at a rate so fast, and on such a curved path, that Heisenberg's Uncertainty Principle comes to mind. Where it is and where it's going may be conjugate variables, but trying to reconcile the two is kind of futile.
In November 2008, the research firm Canalys released its Q3 2008 report on “smartphones”. Worldwide sales were up 28%. Nokia still held the lead with a 38.9% share of shipments, but that was down 3.5% from a year earlier, and the number of phones shipped was down too. Apple meanwhile moved into second place with a 17.3% share, with unit numbers up 523% over the year before. And, that's with just two generations of a single phone—not a fleet of phones such as Nokia's...and everybody else's.
Among operating systems, Symbian was first and Apple second. Following were RIM, Microsoft and Linux, which had a 5.1% share and 49% growth. But that was before Android.
T-Mobile's Android phone hit only last October 17, 2008, early in Q4. Here's a telling quote from the report: “Motorola, currently holding onto fourth place in smartphones thanks largely to its Linux-based models, recently announced it would move away from using the Symbian OS and focus more on Android.” Which is also Linux.
Both the iPhone and the Androids are platforms for running countless applications, only one of which is voice telephony. I know lots of people whose day-to-day digital lives are moving from their laptops to their iPhones, BlackBerries and, yes, Androids. Although the “war” between iPhones, BlackBerries and Androids will attract the most attention, all three will win the battle of computing over telephony in the mobile world.
Still, it's hard to do serious computing apps on networks built for routing calls and charging out minutes. It'll take longer for that battle to be won, but it'll happen too. The phone system will become a data system. It will be borged by the Net.
What happens next is up to developers. For more about that, see this month's EOF column in Linux Journal, “Net Development”, on page 80.

Practical Task Scheduling Deployment
July 20, 2016 12:00 pm CDT
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
