Free to a Good Home: Junk
I was pricing a low-end desktop computer the other day. When configuring it, I noticed that if I added a four-year warranty, it would cost more than the entire system! We've really come to the point where computer hardware is like a plastic fork. If a tine breaks off, it gets thrown away. Sadly, although throwing away plastic forks is rough on the environment, used computers are so much more so.
Thankfully, green is the new pink, and everyone seems to be interested in conservation and recycling. The problem is it's easier to talk about recycling computer hardware than to do it. I work at a school district, and we have a closet full of old CRT monitors just waiting for an opportunity to be recycled. There aren't any recycling places in our area, and thanks to the lead and glass, CRT monitors are very expensive to ship. So, they sit in a closet collecting dust.
Some amazing organizations out there are working hard to focus on another R, and rather than recycling old equipment, they reuse it. Places like Free Geek in Portland, which I had the pleasure of touring last summer, take donated computer parts to create usable systems that are sold or donated back to the community. Thanks to Linux, those systems aren't encumbered with licensing issues. It's really a great way to get working, viable, stable computer systems in the hands of people who would likely never be able to afford one.
Although I'm not suggesting everyone should start a local Free Geek (although how cool would that be!), it's possible someone in your area already is doing something similar. Before you put that 17" CRT monitor and Pentium II computer on the curb, try giving it away in the local newspaper. If you like the idea of building computers for those in need, consider doing a small-scale version of Free Geek in your garage. Don't worry about running out of hardware, the local school district likely has computer parts piled in closets it would love for you to “recycle”. With the power and flexibility of Linux, and the steady supply of aging computers, perhaps the path to world domination is by repurposing last year's Windows computers!
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
