After rocketing its Mathematica application from version 6 to 7 in just 18 months, Wolfram Research's developers may need testing for blood-caffeine content. Mathematica is a powerful general computation environment for calculations, large-scale computations, complex programming, and visualizing and modeling data. After dubbing Mathematica 6 the “most important advance in its 20-year history”, Wolfram says that version 7 is a major release that adds 500 new functions and 12 new application areas. Added functionality includes image processing, built-in parallel HPC, new on-demand curated data and other new computational innovations. The firm further claims that this release has made parallel computing mainstream. Mathematica 7 has 32- and 64-bit editions for Linux x86, Solaris UltraSPARC/x86, Windows and Mac OS X.
The Neuros folks definitely think like we do. Their new Neuros LINK is a hackable, nonproprietary set-top box that connects the television to the Internet via existing open Internet standards. Neuros positions the device “squarely between the dedicated, proprietary electronics devices and the powerful but clunky and expensive personal computer”. One can play downloaded content in virtually any format from any source. Neuros also claims to have created a navigation structure that makes the LINK experience “feel like TV browsing rather than Web browsing”. Currently, the LINK is a Gamma Product—that is, the post-beta, white box preproduction stage especially geared for hackers and hard-core early adopters. Meanwhile, the accompanying Neuros.TV is a free service that enables Neuros LINK users to find, organize and share Web-based video content.
Same dog, new tricks, different owner. In other words, the popular Yellow Dog Linux (YDL) for the Cell Processor has been upgraded to version 6.1 and is now under the tutelage of the company Fixstars. The Tokyo-based Fixstars recently acquired Terra Soft Solutions, the company long associated with YDL. Fixstars states that YDL 6.1 is unique in that it drives both the desktop and development environments forward simultaneously. For end users, YDL v6.1 offers an improved graphical wireless configuration tool and the ability to use PS3 video RAM for temporary storage or swap. For developers, it offers advancements such as the new Cell Superscalar and support for the Cell's programming model. Supported platforms include Apple G4/G5, Sony PS3, YDL PowerStation and IBM Power Systems.
Though still in the prototype stage, a wireless mesh network for ships has been announced by two research institutions: Australia's NICTA and Singapore's Institute for Infocomm Research. Under normal conditions, the maritime system provides data and voice communications between port authorities, container terminals and ships via shore-based WiMax inter-ship connectivity. In poor weather conditions, the system utilizes a backup satellite system. Because, says NICTA, standard VoIP and other data-transport techniques don't work well with satellite systems, the system utilizes onboard mesh nodes and NICTA's mobile routers to handle the satellite connectivity. The shore-based system aims to deliver a 6Mbps long-range (20km) ship-to-ship and ship-to-shore mesh communication system capable of ad hoc multi-hop communication with other vessels and shore command stations.
If we open-source enthusiasts have anything to brag about, it is a great selection of robust databases. A fine case in point is Ingres Corporation's Ingres Database, which was just upgraded to version 9.2. The company bills Ingres as “flexible, simple, secure, reliable and scalable [and able to] cope with even the most complex, multilanguage requirements including business intelligence, content management, data warehousing, enterprise resource planning (ERP) and logistics management”. Core advancements in version 9.2 relate to improved application development, enhanced availability and supportability, as well as the simplification and automation of many tasks traditionally associated with maintaining a business-class database.

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
