Greening your gadgets and lifestyle can be not only fun but money-saving as well. Such is the motto of Joe Hutsko's new book Green Gadgets for Dummies from Wiley, a title billed as a friendly reference for exploring the environmental and financial benefits of green gadgets. Green gadgets encompass everything from iPods to energy-efficient home entertainment devices to solar laptop chargers and crank-powered gizmos. The book explains how to research green gadgets, calculate energy consumption, make a smart purchasing decision, use products you already own in a more environmentally friendly way, and bid farewell to electronics that zap both energy and money. Finally, the book covers product labels and how to avoid “greenwashing”—that is the overselling of environmental benefits.
CoroWare Technologies announced the Explorer, an all-terrain robot designed and optimized for conducting R&D into new robotic applications that operate in unstructured, outdoor environments. Built on a ruggedized chassis, the Explorer functions well outside the lab, navigating rough terrain and resisting environmental elements. The Explorer's camera, wheel encoders and GPS enable the robot to examine the environment while the fully articulated four-wheel drive ensures the Explorer can navigate curbs, steps and inclines. By including a 2.0GHz PC-class processor, 80GB disk storage space and Ubuntu Linux with support for Player Project pre-installed, Explorer is ready to support any software the developer desires. Explorer comes standard with four-wheel drive, 802.11n Wi-Fi, GPS and 1600x1200 color camera. Expansion capabilities exist via extra USB, RS-232, digital I/O and analog inputs. Options include wheel encoders, a pan/tilt/zoom camera and a 64-bit dual-core motherboard.

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
