Open SourceThe administration of Extremadura, an autonomous region of Spain, starts the process of transfer to the Linux and free software jobs in government, which is currently used Windows.

It is planned to move to Linux about 40,000 computers, and for most of the systems migration plan to complete before the end of the year. According to the administration of Extremadura, the transition to Linux will save 30 million euros per year.

Last year was a complete inventory of all software used on workstations state institutions, and developed a detailed plan for migration. To implement the project prepared by the distribution Sysgobex, based on packet-based Debian GNU / Linux and adapted for use in state institutions. Continue reading

Ubuntu 13.04A new version of one of the most popular distributions of Linux today released. A few hours ago the images of Ubuntu 13.04 32/64-bit for desktops and servers, as well as for servers ARM / OMAP posted on the official FTP.

It should be noted that Ubuntu 13.04 is not a long-term release, his life support only up to January 2014, while the previous version of Ubuntu 12.10 – this is a long-term release (LTS), which will be supported until April 2014. So that business users are unlikely to be recommended to do an upgrade from 12.10 to 13.04. Continue reading

Linux FreedomAccording to the latest annual report, prepared jointly by the Linux Foundation and the research company Yeoman Technology Group, for 2011-2012, interest of large enterprises to deploy corporate Linux-based systems, as well as investments in the infrastructure of their work increased significantly.

The survey polled 1,300 largest companies in the world and organizations, including 355 enterprises whose annual income is at least $ 500 million, or whose regular number of employees exceeds 500.

Reportedly, only 2012 business increased its investment in Linux by 12.7%, while investment in Windows have increased by 3.2%, while in Unix decreased by 24.1%. Purchase new servers running Windows are planning in the next five years, only 20% of the companies surveyed, while the number of people willing to invest in the system based on Linux is estimated at 80%.

Open SourceExtension developers MultiPath TCP in the Linux kernel broke the speed record for the biggest bandwidth, which was able to demonstrate in a single TCP-connection.

As part of the experiment was achieved capacity 51.8 Gbit / s data transmission over a single TCP-connection. At that speed to transfer content to DVD quite 1 second, the disc Blu-Ray (25GB) – 5 seconds.

Technology Multipath TCP (RFC 6824) will organize the TCP-connection with delivery packages simultaneously on several different routes through the network interfaces that are bound to different IP-addresses. By applications such aggregated connection looks like a normal TCP-connection. Multipath TCP can be used to increase reliability, and to expand the capacity. As one of the practical applications of Multipath TCP for normal users mentioned the possibility of organizing the data on your phone, using both links WiFi and 3G. For server systems Multipath TCP can provide cost savings through the use of multiple low-cost links instead of one more expensive. Continue reading

Steam LogoValve Company has released an update to the Steam client for Linux. The update was released simultaneously with the version for Windows and contains 15 patches are independent of the underlying platform and 4 changes specific to Linux.

Among the general changes improve navigation, add a new page for the assessment of the most popular content, improved support for extended character sets, advanced logic detection work through a proxy, the ability to automatically recover critical files from the Steam without having access to the network.

Of Linux-specific changes in the support for SDL 2.0 ABI, the problem with the loss of focus and window display without the need for dialogue, setting a new mode driver Big Picture Mode, eliminating hang when sending an error report. Continue reading

LinuxTwo weeks later, with the release of kernel 3.8, Linus Torvalds has closed the window receiving changes to the kernel Linux 3.9 and released the first release candidate (3.9-rc1).

The announcement marked separately integration into the core support two new architectures – metag and arc, and a large number of improvements related to architecture ARM. About 60% of all changes made to the core concern of device drivers (drivers for the GPU, the networking subsystem, staging, pinctrl, sound system, etc.).

The most notable changes in the kernel 3.9:

– Experimental support for RAID5 / 6 in the file system Btrfs, the improvement of the snapshot and the acceleration of the system call fsync ();

– In EXT4 enabled realization of the possibility “punch hole” for the inode, which allows to use the files without the map extents. “Punch hole” allows you to mark the area of ​​the file as a non-binding, which can be clean if necessary. Included developments to improve the efficiency of caching extent and speed up the system call fsync ();

– A number of fixes, optimizations and improvements to F2FS, quite fast file system, focused on Flash-drives; Continue reading

Oracle Linux 6Oracle has introduced the release of industrial distribution in Oracle Linux 6.4, created on the basis of packet-base Red Hat Enterprise Linux 6.4.

Distribution will be available for free download in the assemblies for x86 and x86_64 (iso-size image of 3 GB). In addition, since March 2012, for Oracle Linux open unlimited and free access to the yum-repository with binary package updates with error recovery (errata) and security issues.

Distribution of the differences between Oracle Linux 6.4 on RHEL 6.4 is celebrated bug fixes, updated drivers for network devices and storage systems. As part of Oracle Linux 6.4 comes with two options packages Linux-kernel: a classic version of the company Red Hat (kernel-2.6.32-358.el6) and created by the Oracle kernel package is Linux, based on the branch 3.0 bekportirovaniem some more new features series kernels 3.x (kernel-uek-2.6.39-400.17.1.el6uek). By default, the basic package includes two cores, but prepared in the Oracle kernel package is loaded by default. Ready-core binaries from the Oracle-compatible c RHEL distributions and src.rpm-packets presented on the site public-yum.oracle.com, where you can also download and others present in the distribution packages. Oracle does not impose any restrictions on the supply of trained in the Oracle kernel to third-party products. Continue reading
