Tribler: BitTorrent and Beyond
P2P (peer-to-peer) is the nature of the Net. You can fight that, or you can embrace it. Here in the US, the mainstream entertainment business has mostly been fighting it. Hollywood and its phone and cable company allies have long regarded P2P, and BitTorrent in particular, as a copyright piracy system and a bandwidth hog. In the European Union, however, P2P is more than accepted: it's supported by the Union itself.
Early last year, the EU granted 14 million euros to P2P-Next, a consortium of 21 media companies and universities, including the BBC, Delft University of Technology, the European Broadcasting Union, Lancaster University, Markenfilm, Pioneer Digital Design Centre Limited and VTT Technical Research Centre of Finland. The purpose of the grant is “to develop a Europe-wide 'next-generation' Internet television distribution system, based on P2P and social interaction”. (An additional 5 million euros is also being donated by some of the P2P-Next partners, for a total of 19 million euros.) The project has a four-year span and will include technical trials of new media applications on many devices.
“Everything we're doing is based on open source”, says Johan Pouwelse, PhD, scientific director of P2P-Next and Assistant Professor of Computer Science at Delft. The good doctor also runs P2P-Next's first trial application: Tribler (pronounced “tribe-ler”), a BitTorrent-based client with no servers and a “zero-cost” business model. Tribler provides an all-in-one way to find, consume and share media.
But Tribler goes beyond BitTorrent to support live streaming and other enhancements. The project's Research page lists 26 allied development projects, including six that are already completed and operational. If you're looking to help media evolve past the TV model, there's a rich pile of possibilities on the Tribler project list.
The Tribler download page lists two Linux sources: Ubuntu Linux and “GNU+Linux/Source”.
Check it out, and let us know how it works for you (or, you for it).

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
