Recycle's Friend, Reuse
Recycling is something we all deal with, or at least should deal with, when it comes to technology. Old computers, monitors, motherboards and their ilk are full of toxic chemicals that must be disposed of properly. Thankfully, “Being Green” is a trend that hasn't really lost any steam. As technologists, we understand the need to use less power, recycle old technology and make wise purchasing decisions when it comes to hardware. And, we shouldn't forget recycle's buddies reduce and reuse either.
With modern virtualization, it's possible to reduce the number of servers we need to buy. Add to that the reduction in power usage with low-power CPUs, and it's relatively easy to reduce the amount of waste in our server rooms. Unfortunately, it doesn't eliminate the problem completely. That's where reuse comes into play. In the photo, you'll see a clock I received as a Christmas gift. It's simply the circuit board from some sort of router that has “clock guts” added to it. Geeky yes, but if it's stuck on my wall, it's one fewer piece of computer scrap in a landfill.
No, reusing old technology like this won't solve our technology waste problem, but every little bit helps. Plus, items like my picture frame made from old 30-pin SIMM memory chips make for great conversation pieces. How have you reused technology in nontraditional ways? Send a photo to firstname.lastname@example.org, and I'll post some of them online. Perhaps we'll all get some gift ideas for the next holiday season!
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
