A few months back we had looked at the Abit AW9D i975X motherboard, which was one of the first motherboards to come out of the Universal Abit camp. What we have on the table to look at today is the Abit NF-M2 nView. The NF-M2 nView is an AM2 motherboard that is powered by the NVIDIA GeForce 6150 with nForce 430 that offers both onboard DVI and VGA support along with 7.1 channel HD audio, Abit Silent OTES, and IEEE-1394a Firewire.

Improving KVM Performance With A Tickless Kernel

Filed under
Linux

Avi Kivity suggested that combining KVM, the Kernel-based Virtual Machine, with the dyntick patch could improve overall KVM performance. He noted that it would likely improve performance of both the host by "avoiding expensive vmexits due to useless timer interrupts," as well as on the guest by "reducing the load on the host when the guest is idling (currently an idle guest consumes a few percent cpu)".

Will 2007 be the Year for Linux?

Filed under
Linux

Come February 18th we will usher in the year of the Pig. Looking at Linux in the perspective of the Pig we know that Richard Stallman begun his path down the Open Source road at MIT and Unix version 1 was written in 1971. In 1983 Stallman announced the GNU project and SCO Xenix was released. Outside of these events, there were no other major Open Source events in the Year of the Pig. However, Apple released its first GUI in 1983 and Windows ’95, well I think that speaks for itself. Maybe 2007 will prove to be Linux’s year.

My first impression of the book was that the authors have accumulated much detailed experience. Under the unusual situation that the Linux environment is badly misbehaving, then Linux problem determination requires much learning of the sprawling underlying details.

This is a strange song. It was sung first by fans of Linspire. Now it's Ubuntu. The idea is that bundling all manner of proprietry binary drivers and multimedia codecs, and having 3D special-effects-desktops is necessary to further the cause of Free Software.

Ubuntu

What’s Ubuntu Lite? It’s a new Linux distribution. Its goal is to make a usable Linux-based system that works on 128 MB of RAM. How they plan to achieve this goal seems straightforward: around “lightweight” applications. And it is exactly the wrong way to build a low-footprint distribution. Why?

Drs. Phil Carinas and Dominique Heger are rank-and-file members of the Linux community who have made important contributions to the growth and popularity of Linux -- Carinas through his contributions to the education of Linux users, and Heger through his work on the kernel at IBM's Linux Technology Center. While neither is a superstar whose name is immediately recognizable, they are both important in that they are typical of the thousands of individuals whose contributions, large and small, have turned the world of computing on its ear.

  • Open Source NFV Part Four: Open Source MANO
    Defined in ETSI ISG NFV architecture, MANO (Management and Network Orchestration) is a layer — a combination of multiple functional entities — that manages and orchestrates the cloud infrastructure, resources and services. It is comprised of, mainly, three different entities — NFV Orchestrator, VNF Manager and Virtual Infrastructure Manager (VIM). The figure below highlights the MANO part of the ETSI NFV architecture.
  • After the hype: Where containers make sense for IT organizations
    Container software and its related technologies are on fire, winning the hearts and minds of thousands of developers and catching the attention of hundreds of enterprises, as evidenced by the huge number of attendees at this week’s DockerCon 2016 event. The big tech companies are going all in. Google, IBM, Microsoft and many others were out in full force at DockerCon, scrambling to demonstrate how they’re investing in and supporting containers. Recent surveys indicate that container adoption is surging, with legions of users reporting they’re ready to take the next step and move from testing to production. Such is the popularity of containers that SiliconANGLE founder and theCUBE host John Furrier was prompted to proclaim that, thanks to containers, “DevOps is now mainstream.” That will change the game for those who invest in containers while causing “a world of hurt” for those who have yet to adapt, Furrier said.
  • Is Apstra SDN? Same idea, different angle
    The company’s product, called Apstra Operating System (AOS), takes policies based on the enterprise’s intent and automatically translates them into settings on network devices from multiple vendors. When the IT department wants to add a new component to the data center, AOS is designed to figure out what needed changes would flow from that addition and carry them out. The distributed OS is vendor-agnostic. It will work with devices from Cisco Systems, Hewlett Packard Enterprise, Juniper Networks, Cumulus Networks, the Open Compute Project and others.

Industrial SBC builds on Raspberry Pi Compute Module

On Kickstarter, a “MyPi” industrial SBC using the RPi Compute Module offers a mini-PCIe slot, serial port, wide-range power, and modular expansion. You might wonder why in 2016 someone would introduce a sandwich-style single board computer built around the aging, ARM11 based COM version of the original Raspberry Pi, the Raspberry Pi Compute Module. First off, there are still plenty of industrial applications that don’t need much CPU horsepower, and second, the Compute Module is still the only COM based on Raspberry Pi hardware, although the cheaper, somewhat COM-like Raspberry Pi Zero, which has the same 700MHz processor, comes close.
