Getting cutting-edge IT information from an author's brain to yours more quickly is the mission of Short Cuts, a new line of digital documents from Pearson Technology Group (PTG). Short Cuts are “concise PDF documents about a cutting-edge technology that shows great promise, or an existing technology that has reached the 'tipping point' and is about to take off”, says PTG. The rationale is that when a hot topic comes along, many readers don't want to wait the extra weeks or months needed for the information finally to reach the printed page. Despite the rapid availability, PTG claims that Short Cuts retain the “same level of quality, accuracy, knowledge, and insight” as printed books. The titles span a wide range of IT topics from Pearson's various imprints, including Addison-Wesley Professional, Cisco Press, Exam Cram and Prentice Hall Professional, among others.
ITTIA just released version 1.1 of ITTIA DB, the firm's self-titled, flagship database for deployment in mobile and embedded platforms. ITTIA says that its fully cross-platform database offers developers “fine-grain control over how system resources are used in order to produce efficient mobile and embedded applications...where the limited memory, storage and processing power requirements make software development challenging.” This upgraded version boasts an enhanced C API, increased control over storage size for each file type, an improved interface for accessing BLOB data, modified transaction handling for improved tracking of resource-acquisition bugs and other performance and configuration enhancements. ITTIA notes that many customers utilize its product on embedded Linux platforms, for instance, “HVAC controller systems, physical access control devices and consumer electronics”. You can get an evaluation copy of ITTIA DB from the company's Web site.
The MultiCore Plus SDK from Mercury Computer Systems, now free from the bonds of beta at version 1.0, is a seamless package of software development tools and libraries that enables its users to exploit the Cell Broadband Engine (BE) and other multicore processors fully. According to Mercury, the SDK “includes a comprehensive programming framework, highly optimized math libraries and a graphical IDE with powerful debug and analysis tools”. Furthermore, supported on the open-source Linux distro for the Cell BE processor, the SDK complements components of the IBM SDK. The beta version of the product has been present in applications, such as aerospace and defense, seismic/geologic, semiconductor, life sciences, digital media and national labs. Both Mercury and IBM also offer a range of Cell BE processor-based products.
Yes, folks, RaveHD is a bit esoteric...but that's what makes it so cool! RaveHD's producer, SpectSoft, recently released a major new upgrade to its non-version-numbered product, which is a combination video transport recorder (VTR) and file server for film production. Utilizing Linux and its own in-house software app, RaveHD stores industry-standard DPX frames and makes them accessible via the network, or it can feed those frames to an onboard I/O board as a video stream. DPX frames allow timecode, audio and other material to be packed into each individual frame. The RaveHD hardware must sustain 300Mbps for a video stream for both ingest and playout. However, the hardware exceeds this by far, making RaveHD an ideal file server to feed these frames into other apps. Other tools support particular work flows in the film industry, “such as VFX for dailies and feature film for ingest on-set”, says SpectSoft. RaveHD's latest major features include an auto-router, which “allows the easy routing of any of the SD, HD or Dual Link formats to the various features within the I/O board”, as well as a JPEG push that converts any frame to a JPEG and pushes it either to the RaveHD GUI or any browser. Hey Mom, I know what I want for Christmas!

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
