In our enlightened community, PHP and MySQL are becoming the typical tag team for developing database-driven Web development. If this is your calling, pick up the new 2nd edition of Davis and Phillips' book Learning PHP and MySQL, published by O'Reilly. Intended for newcomers to the technologies, the book teaches both the PHP language and the MySQL database separately and then shows how to merge the two to generate dynamic content. It also contains content on XHTML, error handling, security, HTTP authentication and more.
If your forklift needs a Linux-driven data-capture device, AML hopes you'll use its new MT7570 vehicle mount terminal. The MT7570 is designed for “real-time receiving, put-away, picking and shipping applications in harsh industrial environments”, and it integrates securely into existing wireless networks. Full USB and RS-232 serial connections, as well as optional Bluetooth WPAN communications, provide connectivity to peripheral devices, such as bar-code scanners and printers. Construction is rugged. The MT7570 has a bright display for dimly lit environments and can withstand dust and water deluges. The device is available with either embedded Linux or Windows XPe, and both systems include terminal emulators (VT100/220, TN5250, TN3270), Web browsers and a Skype client.
Silicon Mechanics recently rolled out its new Bladeform 8100 Series of blade servers. The firm describes the line as “a family of modular computing products designed to address a wide range of high-density computing challenges by allowing multiple servers to be contained within one easy-to-manage system.” Series components include the blade server enclosure, the 8110 server blade (dual Intel Xeon), modular networking and interconnect components. Some of the key features include a modular enclosure with support for up to ten server blades, up to four redundant load-balancing power modules, 90%+ efficient power supplies, up to 2GB Ethernet switches with ten external ports each, InfiniBand expansion adapters and switch support, and remote management capabilities.
We've been informed of HPC Systems' HiPerStor, a new line of network-attached storage products. The line is targeted at three different product segments, namely SOHO/home, SMB and SMB with advanced needs. The line also features iSCSI technology, upgrade to InfiniBand, TOE NICs or 10GbE NIC, integrated volume replication and snapshot, support for disk encryption, secure Web-based management, a range of user-authentication options and more.
We bid a warm Linux-community welcome to Integrated Computer Solutions, which recently released version 3.1.1 of UIM/X, a client/server application-development tool that now also runs on Linux. UIM/X enables developers to build Motif GUIs “in a fraction of the time it takes by hand”, say the folks at Integrated. They also claim that UIM enhances programmer productivity by enabling the creation, modification, testing and code generation for the user interface portion of an application with a single tool. UIM/X supports the most current version of Motif (2.x) and runs on Solaris, HP-UX and Red Hat Linux.
At LinuxWorld San Francisco, Black Duck Software announced version 4.4 of the firm's protexIP/development, “a platform that helps companies govern how their software assets are created, managed and licensed.” ProtexIP helps developers and legal counsel in managing the use of code from open-source projects that have both decided to switch to GPLv3 explicitly and those that have decided not to switch. It also includes an enhanced KnowledgeBase, a library of open-source and vendor-added code software components that includes detailed licensing information for more than 140,000 components.

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
