Run with MeeGo
Any device that will run MeeGo needs two things: the MeeGo core software stack and the MeeGo User eXperience (UX) for that specific device, although you are not limited to using the MeeGo UX, and you can create and deploy your own branded UX. Currently, MeeGo is available for Netbooks, IVI and handsets.
The MeeGo Core 1.1 release provides a common base operating system for the user experiences of all supported device categories. It provides a complete set of enabling technologies for mobile computing. The MeeGo stack contains Linux kernel 2.6.35, X.org server 1.9.0, Web Runtime, Qt 4.7 and Qt Mobility 1.0.2, supporting the contacts, location, messaging, multimedia, and sensor and service frameworks. It also includes a number of leading-edge components, such as the oFono telephony stack, the ConnMan connection manager, the Tracker data indexer, the Telepathy real-time communications framework, the Buteo sync framework and many more.
These technologies are brought to application developers through the MeeGo API, which is based on Qt and other technologies, such as the MeeGo Touch Framework. With the latest Qt version 4.7, the MeeGo developer experience is now enhanced with the introduction of QML, the easy-to-use scripting technology for animated touch-enabled GUI apps.

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
