Barnes and Noble's Nook
Overall, I like the Nook. Since I got my Nook, I've found myself “unplugging” from the computer and reading more. I like my Nook so much that the day after I got mine, I ran back to Barnes & Noble and bought my wife a Wi-Fi Nook. If I had to make the purchase again, I'd have gotten a Wi-Fi-only Nook myself, as I've used the 3G to purchase a book exactly once. The Nook's shortcomings aren't showstoppers to owning one, unless you need to rely on its Web browsing ability or need the fastest in screen refresh—in which case you probably shouldn't get any E Ink e-reader. It's hard to go wrong with the Wi-Fi Nook at the current $149 price point, and although the extra $50 for the 3G probably won't bankrupt anyone, it's more gimmicky than functional, as it's not very hard to find Wi-Fi around for downloading books. At any rate, if you're in the market for a dedicated e-reader, check out the Nook.
Managing Your Content with Calibre
Calibre is a cross-platform open-source program that's designed to manage electronic books and other texts. It'll convert between e-reader formats as well as PC formats, like PDF and HTML, and it will download cover art and other e-book attributes automatically from the Internet. It's really easy to use, and it syncs with the Nook flawlessly. If you have a lot of pre-existing content in other formats you want to put on your Nook, Calibre's the only way to go.
Softrooting the Nook
The Nook is an Android device, and as such, is capable of being “rooted”, giving you full access to the hardware via the removal of software constraints. The softroot for the Nook is fairly easy to do, and you can do simply by downloading and installing a couple firmware bundles. After your Nook's been softrooted, you'll have the ability to change the launcher's main menu icons, as well as install other Android apps like Pandora. There are a couple Nook-specific applications as well: Trook (a way to download books you already own via Wi-Fi outside of the Barnes & Noble store) and Twook (a Twitter client with many of the same faults as the Web browser app). Note that at the time of this writing, new Nooks with serial numbers starting in the 1003 series are not compatible with the current softroot. Take care and check with the NookDevs site (see Resources) before attempting a softroot. If in doubt, don't do it!

Practical Task Scheduling Deployment
July 20, 2016 12:00 pm CDT
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
