Donald E. Knuth's monumental book series The Art of Computer Programming has deep roots. When the distinguished Stanford Professor Emeritus Knuth began putting his ideas to paper, John F. Kennedy was president, Don Draper was Madison Avenue's hottest ad man, and most of us were merely potential zygotes. Publisher Addison-Wesley says that the first three volumes of Art of Computer Programming are “widely recognized as the definitive description of classical computer science”. Practicing programmers have long applied his “cookbook” solutions to their day-to-day problems. Now comes the long-awaited fourth volume to compose a new four-volume set. The new volume 4 brings together definitive new coverage of broadword computation, combinatorial generation, fundamental combinatorial objects and other topics. Bill Gates has said that people who read the entire set should send him their résumé. If you get that far, we imagine Linus would love to see it too!
The OpenERP open-source suite of comprehensive business applications recently bounded up to version 6.0. OpenERP's eponymous developer noted that a number of factors warranted the release's designation, including advancement in simplicity and ease of deployment, the ability to build an ERP system at one's own pace, greatly improved affordability and accessibility for companies of all sizes, and more than 800 contributions from its global community of open-source developers. Further, OpenERP v6 now is available not only as an on-site version, but also as an SaaS platform, which the firm says “radically reduces the cost and complexity of an ERP deployment”. Some of the hundreds of additional new features include extended multicompany functionality marketing campaign management, simplified accounting interface, tracking of tickets for support and after-sales services, push and pulled logistics flows, talent acquisition and manufacturing scrap management.
The developers at GrammaTech have released a fresh new version 3.6 of CodeSonar, a source code analysis tool that performs a whole-program, interprocedural analysis on code and identifies complex programming bugs. Version 3.6 adds two significant improvements, namely a significantly improved GUI, which streamlines developer interaction and boosts productivity, as well as a more efficient analysis engine, which can reduce analysis time on large code bases, says GrammaTech, by up to a third. GrammaTech also says that CodeSonar's unique strength is “its ability to identify far more program-crashing defects and security vulnerabilities than competing static-analysis tools”. Another advantage is CodeSonar's new GUI that “enables developers to quickly digest key information, understand and identify the most important issues and prioritize fixes”. CodeSonar runs on Linux, Solaris, Windows and Mac OS X operating systems and supports most compilers.
The developers over at The Document Foundation are giddy about their new LibreOffice 3.3, the first stable release of this free, power-packed and open-source personal productivity suite for Linux, Windows and Macintosh. Based on and containing all features of OpenOffice.org, LibreOffice contains the Writer, Calc, Impress, Draw, Math and Base applications. Some of the many new features include compatibility with SVG files, improved ergonomics in Calc, and Microsoft Works and Lotus Word Pro document import filters. The Document Foundation says it now has more than 100 developers working on LibreOffice.
Bibble Labs' bills its new Bibble Pro and Bibble Lite, both nudging up to version 5.2, as “an ambitious project to revolutionize digital photographic workflow”, streamlining it to run “at the speed of light”. The applications, according to Bibble Labs, offer tools for photographic editing and organizing capabilities all at “blazing speed in a sleek, modern interface”. Version 5.2 adds, among other things, support for 14 new RAW formats, including Nikon D3100, D7000, P7000 and Panasonic LX5, GF2 and GH2, and includes significant improvements to the application's selective editing capability. Both Bibble 5.2 Pro and Bibble 5.2 Lite are available for Linux, Windows and Mac OS.

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
