CherryPal PC: Linux and Green Go Together
I am so proud of the Linux Community for many reasons, but I’m amazed at how well it continues to impress the ‘greenie’ in me.
Until this week, we had three stand-outs in the ultra-environmentally-friendly department - the cool Zonbu desktop and laptop, and the fit-PC (for the record, yes, you can get Windows XP on the fit-PC, too). Just this week, a svelte and diminutive yet powerful new entrant arrived on the scene, i.e. the CherryPal PC. The CherryPal’s green cred is strong. While a typical desktop PC uses around 114 Watts, the CherryPal uses only 2 Watts. It has no moving parts and uses 80% fewer parts than a standard desktop PC. However, it does not appear that the CherryPal supports the RoHS standards for eco-friendly construction.
Beyond its green characteristics, the CherryPal has other interesting qualities. As with the Zonbu PC, CherryPal leaves application and storage management to the manufacturer. It uses a customized Debian OS with the OS and browser collapsed into a single layer for improved speed and security. Local storage occurs on a 4 GB flash drive. The CherryPal also sports the Freescale’s MPC5121e mobileGT processor and 256 MB of DDR2 DRAM.
Even if you aren’t a greenie, you may want to check out the CherryPal or one of the other green PCs to save yourself some green. The company claims that if you run your standard desktop PC 8 hours a day, you will spend an average of $37 per year on electricity and emit about 300 pounds of CO-2 into the atmosphere. If you use a CherryPal, they say, you’ll spend only 65 cents per year and emit only 5 pounds of CO-2.
If I add up all of the PCs in my household, that is a good chunk of change. Maybe it is easy being green after all!

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
