The Coraid folks have released a free-standing tower version of their EtherDrive Storage Appliance, christened the SR1521T. The SR1521T, with internal RAID, provides true networked storage over standard Ethernet and is based on the open ATA over Ethernet (AoE) protocol. Coraid says that “AoE is a block level storage protocol that is simpler to implement than other SAN technologies and at considerably less cost than iSCSI and Fibre Channel solutions.” Further, because AoE is non-routed, “the need for TCP/IP processing overhead or expensive network adapters” is eliminated. The target customers are those that do not seek a rackmounted solution and “that need powerful and scalable network storage readily available at the departmental level”. The AoE protocol is native in the Linux 2.6 kernel, and software drivers are available for Mac OS X, Windows, Solaris and FreeBSD.
Arcosoft joins the growing list of companies that have come to their senses: it just released a Linux version of its VONaLink TeamRecord VoIP-based call-recording application. TeamRecord works with any VoIP phone system based on the SIP standard (think Asterisk), centrally recording all phone calls for a company's workgroup. VONaLink says that TeamRecord, for instance, allows “business transactions over the phone to be verified and disputes resolved” or comply with Sarbanes-Oxley or other disclosure provisions. Furthermore, TeamRecord replaces both expensive analog recording equipment and proprietary products from the dreaded phone company. The recording process involves unobtrusive monitoring of network packets via the port mirroring capability of a network switch and results in an inaudibly watermarked MP3 or WAV file. Users can listen to recordings of their own calls from a Web browser. TeamRecord is available for x86 Linux and Windows platforms.
When not spending time in Amsterdam's offbeat cafï¿½, the members of Dyne.org are busy developing dyne:bolic, upgraded to version 2.4, a live-or-installed Linux distribution focused on the needs of media-production fanatics. The main advantages of dyne:bolic include recognition of a wide variety of devices and peripherals, numerous tools for recording, editing, encoding and streaming audio and video, and the ability to run on lower-powered hardware. New in version 2.4 are improved user-friendliness via the Xfce-4.4 desktop, encrypted nests for preventing access to personal data stored in home directories, new (QParted) and updated (Cinelerra) software and a modularization of the inclusion of different kernels. You also can run (the previous edition of) dyne:bolic on “modded Xbox game consoles” and even cluster them! Raw ISO CD images can be downloaded for free or purchased for a minimal cost.

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
