PIC Programming with Linux
Make sure the programmer is connected and the processor is plugged in correctly. Press the R key from the main menu and the data from the processor will be read into the internal buffer; its clock type and fuse states will be displayed on the second line of the display. As it is reading, picprg will display every 16th address, just to let you know it is working correctly.
With the programmer connected and the processor plugged in the right direction, press P to start the programming process. The data in RAM will be written to the PIC and the third line will display “Programming PIC”. If any errors are found, they will be displayed with the address, the value read from the PIC during the failed verify and the value expected. Every 16th address it programs will be displayed, assuring you that it is still working.
From this point, it's up to you to learn how to write programs for the PIC. Many useful sites which can help you on your way are on the Internet; David Tait's list of PIC resources is the best starting point.

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
