Ideas Wanted: Creative Heat Recycling from Servers
The University of Notre Dame heats a botanical garden with waste server heat. We're looking for more creative ideas from you on recycling waste server heat.
The botanical garden that is heated by Notre Dame's servers specializes in desert plants and is located in Indiana, well know for its brutal winters. The concept is simple. The waste server heat is pumped into the interior space of the garden to keep the desert-loving plants toasty warm all year long. This simple, creative step is saving the university $100,000 on cooling costs and the owner of the botanical garden, the City of South Bend, Indiana, another $70,000 on heating costs. Not only that, but the atmosphere is spared many thousands of tons of pollution from carbon emissions. That is quite a triple win-win-win arrangement.
This leads me to my challenge to you. Have you ever worked on or heard about creative solutions like this, where waste heat from servers or data centers is recycled (or managed) in a non-traditional way that conserves energy? If so, we'd love to hear about it. We'll discuss your responses in a future edition of my new blog on environmentally friendly computing, The Green Penguin.
To make this more interesting, there are free t-shirts for the most interesting submissions! Send your stories to me, James Gray, Linux Journal Products Editor, at firstname.lastname@example.org. I look forward to reading them.

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
