Across the pond at Germany's big LinuxTag event, Ksplice unveiled Ksplice Uptrack, a new service that installs security and bug fixes on a running kernel without rebooting. Ksplice, whose technology was developed at MIT, claims to be the only solution that allows this application of updates without rebooting. Currently available for Ubuntu 9.04, Uptrack supports generic, virtual and server kernels. It also works in VMware, Xen, Virtuozzo or other virtualized environments. Although the initial release is a consumer-oriented solution, an enterprise solution is expected in Q3 2009. [See the August 2009 issue for a feature article on Ksplice.]
The company Fixstars (formerly Terra Soft of Yellow Dog Linux fame) keeps cranking out juicy goodies for the PS3 and other Cell-based platforms. The latest solution is the CodecSys CE-10 product, a faster-than-real-time H.264 video encoder that runs off a live USB stick or CD on the Sony PS3 using a microversion of Yellow Dog Linux as its live OS. In the solution, the PS3 acts as an external accelerator, encoding video files sent from the host PC, replacing expensive encoder cards and workstations. The PS3 is connected via Gigabit cable. The H.264 format allows for compression to half the size of MPEG2 for DVD and TV broadcasting while retaining equivalent quality.
Entuity's new network management solution, Eye of the Storm Network Professional Edition (or EYE NPE for short) is now available. The company says that EYE NPE offers “enterprise functionality at a price point previously reserved for workgroup-class tools” and adds “revolutionary technology for the mid-market” regarding automation, accuracy and deep functionality. Other product advantages include automatic surveying of networks in real time, an intelligent view of object connectivity, root-cause analysis and a broad range of configurable thresholds. Furthermore, rather than a device-centric approach, EYE NPE includes user-configurable views that represent any logical collection of devices or segmentation of the network. The solution runs on RHEL Server, VMware ESX Server and Microsoft Windows Server.
Just in at the education desk is mimio Studio 6, the latest release of mimio's interactive teaching software. The application is one element—together with the mimio Interactive System, a projector and mimio Ink Capture Kit—in a system of presenting interactive lessons to students in schools. One can interact directly with the system, as well as import a wide variety of external media. New features in version 6 include support for multimedia files, a gallery for fast lesson creation and a slimmer toolbar. Interesting for us Linux geeks is that the system now works with Linux and Mac OS in addition to Windows, enabling a lesson created on one platform to run on all three.
Building on numerous improvements in the Wine Project, CodeWeavers has released version 8.0 of its popular CrossOver Linux and CrossOver Mac products. These products respectively transform Linux and Mac OS X into Windows-compatible operating systems for selected applications. Both products, says CodeWeavers, include support for Internet Explorer 7, Quicken 2009 and performance upgrades for Microsoft Office 2007, particularly Outlook. In addition, users will find that many other previously supported applications will run much faster and more stably. The company further offers that all of its products are significantly less expensive than the cost of a Windows license, allowing users economically and legally to eliminate the need for Microsoft Windows. (And there was much rejoicing.)
The company Opera (of browser fame) says that its new Opera Unite is a new technology that will shake up the old client-server computing model of the Web and “decentralize and democratize the cloud”. Essentially, Opera Unite is a Web server on the Web browser. It turns any computer into both a client and a server, allowing it to interact with and serve content to other computers directly across the Web, without the need for third-party servers. For consumers, Opera Unite offers greater control of private data and makes it easy to share data with any device equipped with a Web browser. For Web developers, Opera Unite services are based on open Web standards, and creating a full Web service is as easy as coding a Web page. Currently, Opera Unite offers six services: file sharing, Web server, media player, photo sharing, “The Lounge” chat service and “The Fridge” message exchange.

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
