While the Opera Web browser has yet to conquer our readers' PCs, the browser maker appears to have had more success on mobile devices. Case in point is Opera Mobile, now in version 10, the cross-platform UI framework for Android, BREW, Windows Mobile and Symbian/S60 smartphones. Opera says that Mobile 10's raison d'être is to open up the Opera browser experience to more people, on more devices, allowing “operators and OEMs to implement the same user experience quickly and cost effectively across their entire range of handsets”. Other features include a rich Web 2.0 experience optimized for mobile phones, Opera Turbo data compression technology and the Opera Widgets standalone mini-Web apps.
Following on the success of DeviceVM's Splashtop application, Mandriva has introduced InstantOn, a Linux-based application that brings up a usable interface on virtually any PC in a matter of seconds. Designed to complement a base operating system (Linux or Windows), InstantOn offers a choice of applications for near instant display—that is, less than ten seconds and even less than that for hard drives with Flash memory. Applications include Firefox, Rhythmbox, Pidgin, Skype and Thunderbird. An OEM version will offer a customizable interface and 20,000 applications from which to choose.
Although we failed miserably on getting you this info by Christmas, let us hook you up for Valentine's Day gift-giving (and receiving!). The chicboom Keychain Speaker is designed for the stylish woman who wants a big, mobile sound in a small package. The amplified speaker, which one can attach to any device with a standard 3.5mm stereo jack (MP3s, iPods, laptops and so on), needs only 2 Watts and runs a full four hours on a single charge.
Editor Kevlin Henney has distilled essential wisdom from the programming craft into one concise O'Reilly volume, titled 97 Things Every Programmer Should Know: Collective Wisdom from the Experts. The book contains 97 “short and extremely useful programming tips” from some of the most experienced and respected practitioners in the industry, including Uncle Bob Martin, Scott Meyers, Dan North, Linda Rising, Udi Dahan, Neal Ford and many others. These veterans encourage programmers to push their craft forward by learning new languages, looking at problems in new ways, following specific practices, taking responsibility for their work and becoming as good as possible at the entire art and science of programming. The focus is on practical principles that apply to projects of all types. One can read the book end to end or browse it to find topics of particular interest.
Now in its second edition, Randall Hyde's The Art of Assembly Language from No Starch Press has been updated thoroughly to reflect recent changes to the High Level Assembler (HLA) language, the book's primary teaching tool. The comprehensive, 800-page guide teaches programmers how to understand assembly language and how to use it to write powerful, efficient code. It further demonstrates how to leverage one's knowledge of high-level programming languages to make it easier to grasp basic assembly concepts quickly. All code from the book is portable to the Linux, Mac OS X, FreeBSD and Windows operating systems.

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
