Motorola started tinkering with Linux on mobile phones as an experiment in China, which was supported, interestingly, by the Chinese government. Because the company was so impressed with Linux, our beloved OS is becoming ever-more common on its mobile devices. One of the latest Linux-powered options is the RAZR2 V8, a next-generation edition of this popular handset line. The RAZR2 V8 features up to 500 minutes of talk time, quad-band connectivity, up to 2GB of memory, a two-megapixel camera, Opera Web browser, independent speech recognition and music management based on Windows Media Player 11. Motorola was coy about the latter feature, divulging only that it has licensed audio codecs, DRM and transfer protocols from Microsoft and integrated them into its Linux-Java platform. Still, it calms the Linux-questing soul to know that one can intentionally go out and get a butt-kicking Linux-based phone!
If qmail's home page is too unwieldy for you, pick up Kyle Wheeler's Qmail Quickstarter, a new book for folks familiar with Linux/UNIX and DNS servers who desire to set up a qmail mail server. Starting with the basics, Qmail Quickstarter moves on to getting e-mail messages in and out of the queue, along with storing, retrieving and authenticating them. The book also covers virtualisation of domains and user management, filtering spam, SSL encryption and mailing lists. Packt says that the book's style focuses on practical examples that system administrators can use right away, but that it also explains the rationale behind every example.
Axigen continues to add to the feature set of its Mail Server messaging solution, with version 4.0 now shipping. The key new feature in version 4.0 is a Personal Organizer module offering features such as calendaring, tasks, journal, notes and collaborative support. The feature is available via Axigen's WebMail interface and Outlook clients. In addition, the product now contains the Axigen Outlook Connector, which implements most Exchange-like features, such as server-side search folders. Axigen Mail Server comes in three additions: ISP/HSP, Business and a free Office edition.
As the Detroit automakers obsessively perfect the cupholder, Drew Technologies seeks to sneak a slick Linux-based device, the DashDAQ, on board your new ride. The DashDAQ, says DrewTech, is “a cross between an automotive gauge, dashboard, navigation system, data acquisition system, trip recorder, diagnostic tool and a handheld computer.” The device was designed for use as an automotive display, includes OBD2 communications protocols and runs on Linux (yesss!). The software that is included with DashDAQ allows users to create their own themes and automotive gauge skins. Other features include dual-ARM architecture, 4" (QWVGA) 24-bit TFT color display, a touchscreen and 64MB of RAM. The product is available through resellers, distributors and directly from DrewTech.
Book publishers seem to release their books in waves, and presently we find ourselves in the midst of a geek-book tsunami. The ever-eclectic No Starch Press continues to pack its LEGO Mindstorms series with fun titles, the latest being Forbidden LEGO by Ulrik Pilegaard and Mike Dooley, subtitled cheekily as “Build the Models Your Parents Warned You Against”. Presto, rebellion accomplished! Forbidden LEGO focuses on “free-style building” and shows you how to make zany models, such as “a toy gun that shoots LEGO plates, a candy catapult, a high-voltage LEGO vehicle, a continuous-fire ping-pong ball launcher and other useless but incredibly fun inventions.” A word to the wise: stock up on LEGOs in advance!

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
