Finnix a live distro for sysadmins is available in version 105th For the first time the developers have used their own build tool, which replaces the previous manual work.

NEALE (Normalized Extraction and Assembly of LiveCD Environments) builds Finnix CDs from a minimal Debian bootstrap. The configuration of the system via packages “Finnix-base” and “Finnix-standard” to get the desired function via software on board. Of these, the developers promise a consistent build process, the error is minimized, and even across hardware architectures. The Finnix Build-stage scripts are also supported.

DirectFB – a lightweight library that provides hardware acceleration, access to input devices, which contains built-in windowing system with support for translucent windows and multiple layers. It can operate as a standard framebuffer (/ dev / fb), and through other output device.

DirectFB is aimed at embedded systems and sets a new standard for graphics under Linux.

Mozilla has lost on its own judgment for the fight against WebM and H.264 as the primary video format on the web. As the mobile versions of the browser can not rely on Flash, Mozilla will support the H.264 hardware decoding.

After Google bought the company and the On2 video codec as WebM was released , Mozilla supported efforts to make WebM also the preferred format for HTML5 video. But with the HTML5 standardization in this respect there was no agreement . How, then, Brendan Eich of Mozilla notes , H.264 has won the Web and in the mobile space combat. In the latter, H.264 is a standard format, and the Web are still a lot more videos in the H.264 format to find than others. Even Google has not even half of the YouTube videos to WebM changed, and calibration doubts that it will be even more. For all the videos, was built in the advertising, H.264. Whether this is due to technical reasons, is not apparent from the blog.

Red Hat is the eighth update of Red Hat Enterprise Linux 5 released, which brings better hardware support, minor software updates and corrections. In addition, the new version includes all previously released security updates to.

The latest update to the company’s distribution from Red Hat is on an extended kernel 2.6.18 on. Some of the new features in Red Hat Enterprise Linux was (RHEL) 5.8 in RHEL 6 introduced and integrated into the older version. Thus, the support of virtualized environments on RHEL 5 has been expanded. Virtualized guest under KVM can use immediately from now instead of 128 to 256 cores. In addition, the Spice client only supports the recently released Red Hat Enterprise Virtualization 3.0, Red Hat Enterprise Linux 6.2 systems. The company also has improved support for virtualization in hardware timer, which according to statement from Red Hat to lead to, among other things one at a quicker start and accelerated environments. Xen environments, however, the log information and the system can donated to change the size of virtual hard disks also switched hosts.

Since 2001 I’ve had a VDR in use, after a few years, the hardware was over and I’m miserable if the television program waives a VDR.

It has happened in the meantime a lot, now is the HD support with VDR as a stable view, the issue is no longer on the DVB card, but an Nvidia card that VPAU governed under Linux so that the decompression of the DVB- Streams in the graphics engine made. After 5 years of abstinence, I am now so come back to the VDR. In this article I have written as a reminder of my configuration.

The tool collection hardware Locality (Hwloc), system components such as processor cores and cache is mapped in version 1.4 available with new features.

The new version under the heading of “ multi-node topologies , “with an interface and tools to investigate not only individual computers, but entire cluster and map. There are Linux and Solaris, the new attributes “CPUModel” and “CPUTYPE” for socket objects. Advanced features help computing on NVIDIA GPUs with CUDA.

In the new kernel release puts 3.1, provides support for new hardware. He also reduced latencies in the operation of SSDs with LVM2/Mdadm. Other enhancements include Xen with dom0 and PCI passthrough and nested virtualization with KVM. The software inventory comes from Debian unstable (Sid) and dated 31 December 2011.

The well-known manufacturer of programmable logic chips, the company Altera , presented to the public project to create a tool to execute on FPGA code written for OpenCL. OpenCL is based on C open standard for parallel programming. He is currently actively used for transfer to the graphics card computations requiring high performance. Interest in the graphics card was called primarily to the fact that they are used in processors can simultaneously execute a large number of operations that can achieve tremendous performance on a well-parallelizable tasks. These considerations prompted the developers to pay attention to the FPGA. Altera has become a member of the OpenCL working group in January last year.

Project developers OpenRISC announced the establishment of fees for development , created specifically to build a SoC based OpenRISC. The board supports the most common interface is small (80 x 40 mm), easy to use and debug. The developers have positioned it as a budget solution for working with FPGA , aimed, first and foremost on the community.The main objective of this step – bringing to the project of new users and developers.

The Khronos Group has published the OpenCL open standard in version 1.2. The downward-compatible new specification brings more speed and some new features.

The Khronos Group is an industry consortium of vendors and users of graphics hardware and software. In December 2008, it turned OpenCL 1.0 before, “the first open and platform-independent standard for” heterogeneous parallel programming.

This version was OpenCL 1.1 in June 2010. OpenCL specified interfaces that allow time-intensive computations can be distributed across multiple CPUs and GPUs. Many drivers and libraries now implement the specification.

OpenCL is an open standard that can be used by anyone free of charge. The new version 1.2 includes enhanced features compared to version 1.1 and will allow more flexibility and higher speed. About thirty companies were involved in the new version.
