Fun with E-Ink, X and Gumstix
A lot of work has been going on to enrich the Gumstix toolset and provide better integration with the AM200 kit. Projects like OpenEmbedded are simplifying embedded Linux work. I see a bright future for these displays (no pun intended). I don't think it will be much longer before we have displays that we can roll up just like paper and stuff in our back pockets. The costs will come down, and we'll be able to scatter them on a desk just like regular paper and treat them as extensions of our normal desktop display. Linux will continue to be at the forefront of this with its unique capabilities.
The author is grateful to E-Ink engineers for their extensive support and hardware help, and to Andrew Morton, Peter Zijlstra, Antonino Daplas, Paul Mundt, Geert Uytterhoeven, Hugh Dickins, James Simmons and others for code review, mm, fbdev and general help.

Jaya Kumar has been enjoying Linux since 1995 and is the author and maintainer of deferred IO, the fbdev drivers for E-Ink controllers. He is on a constant lookout for chocolate kulfi as well as cool new technologies to hack on and welcomes any and all feedback at firstname.lastname@example.org.
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
