Happy Hacking Keyboard
As a part-time game player (Linux Quake), I'm accustomed to using the keyboard for all player movements, such as turns and running. With this keyboard, I'd have to hold the function key down constantly (to select the arrow keys) or figure out how to use the mouse. Otherwise, keeping the function key depressed (two keys away from the arrow keys) and trying to fumble around with the arrows might increase the probability of developing carpal tunnel syndrome.
After a few games of Quake, I think I'll be comfortable with the bizarre fingering required. Also, using the keyboard to program in XEmacs helped in the adjustment needed to get into the gaming world.
Documentation is also available on-line. While I haven't had to use their tech support e-mail, it is readily available—my contact at PFU America was quick to reply to any e-mail I sent. Furthermore, all of the information needed to install and hook up the keyboard can be found on-line. All of the information in the manual is included in their on-line documentation.
Overall, I would be hard-pressed to sum up this review with anything but a positive remark. With the price tag recently dropping by $40, the keyboard is more affordable. I'm sure other hackers will be quite happy to own it.
For someone who hasn't experienced the keyboard, it's hard to believe everything reported about the Happy Hacking Keyboard by PFU America. In fact, I was skeptical about the remarks I had heard before I became a Happy Hacking Keyboard user. Now, one month after laying my fingers on it, I can't imagine using any other keyboard. I wonder if PFU America makes a Happy Hacking tote bag.
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
