mấy tháng gần đây là thời điểm ra mắt các phiên bản mới của các hệ điều hành nguồn mở như Ubuntu, LinuxMint, CentOS, và giờ là Fedora.(còn nhiều cái khác nữa) Fedora 13 Codename: Goddard ra mắt ngày 25/5 vừa rồi Upgrade trực tiếp bằng hướng dẫn sau: http://fedoraproject.org/wiki/Upgrading_Fedora_using_yum hoặc download tại đây: http://fedoraproject.org/get-fedora có gì mới??? 3D Support for Nvidia Systems In addition to the experimental 3D support for certain ATI chipsets introduced in Fedora 12 the mesa-dri-drivers-experimental package now includes 3D support for Nvidia systems via the free and open source Nouveau driver and your early testing and feedback is appreciated. Improved Software management Performance of RPM has improved considerably with the integration of RPM 4.8 Beta 1 which is included in this release. A number of other enhancements included ordered erasures, smarter dependency loop handling, revamped Python bindings including compatibility with Python 3.x and a large number of bug fixes. For more details refer to the official announcement by Panu Matilainen from Red Hat. Topology Awareness Both the kernel space file system code and the IO stack now have the ability to use information from certain types of storage about how best to layout data. Specifically, the kernel exports information about the optimal byte alignment for a partition, the optimal and minimum IO sizes and whether or not the device is rotational. This work is done in the kernel, users can query /sys/block/sda/queue for example to see these and other parameters. Note that not all storage devices export this information and that work is ongoing to take advantage of this information in the various file system tools like mkfs. Enhanced Init System Upstart has been updated to 0.6 which provides an incremental step towards moving to native Upstart scripts in a subsequent release of Fedora. Installer Changes The Anaconda installation program's user interface has been upgraded, with a simpler workflow for desktop and laptop users, enhanced options for advanced storage usage, and more understandable dialogs. Of course it still retains the powerful kickstart capability for automating the installation process. The /boot partition now defaults to a size of 500 MB during a fresh installation, to aid in later use of PreUpgrade and the dracut utility. On systems with more than 50 GB of free space, the /home partition is now created separately during a fresh installation. A separate /home partition makes it easier to perform some backup, upgrade, encryption, and re-installation procedures. Firefox 3.6 Web Browser Firefox 3.6.1 is included in this release. In Firefox 3.6 Personas are built in. HTML 5 video can now be displayed in full screen, support for the WOFF dont format is added, and better Javascript support which includes better speed and improved overall browser responsiveness. Firefox 3.6 uses the Gecko 1.9.2 web rendering platform which renders web pages faster and provides support for the new CSS, DOM and HTML 5 web technologies. Webcam Support Fedora 13 now includes out-of-the-box webcam support for many so called dual-mode cameras. These are cheap still cameras (which usually hold only on board storage, no memory card slot), which can can also function as a webcam. For a list of all webcams and applications with which Fedora 13's improved webcam support has been tested, refer to the BetterWebcamSupport feature page. NetworkManager A command line interface (CLI) for NetworkManager is included in Fedora 13. The NetworkManager applet contains support for current signal strength, cellular technology (GPRS/EDGE/UMTS/HSPA or 1x/EVDO etc), and roaming status for Mobile Broadband connections. NetworkManager now has support for connecting to the internet using a cell-phone paired via Bluetooth using Bluetooth Dial-up Networking (DUN). User level MPI A rethink of MPI software management has been made in Fedora and relevant packaging guidelines have been adopted for Fedora 13. Instead of the system-wide alternatives system, support for MPI compilers and runtimes is now managed at userlevel in Fedora with environment modules. The compilers, runtimes and any software compiled against them are installed in separate directories outside the $PATH. Now, for example, it is possible to run program A in one terminal session with Open MPI and program B with MPICH2 in another session. For this reason no default MPI runtime is set by default. To load support for Open MPI on Fedora 13 x86_64 run $ module load openmpi-x86_64 and for MPICH2 $ module load mpich2-x86_64. If you want e.g. Open MPI support to be automatically available in your sessions, add the command above to your shell config. [These changes may have already happened on Fedora 11 and/or Fedora 12, depending on the MPI runtime one has been using.] Linux Kernel 2.6.32 A number of features including memory de-deduplication and ATI R600/700 3D and KMS support in this kernel release was driven by Fedora and already part of Fedora 12 but this kernel includes several other significant features including a rewrite of the writeback code which provides noticeable performance speedups, many important Btrfs improvements and speedups, other graphic improvements, a CFQ low latency mode, tracing improvements including a "perf timechart" tool that tries to be a better bootchart, soft limits in the memory controller, support for Intel Moorestown and its new firmware interface, run time power management support, and many other improvements and new drivers. More details at http://kernelnewbies.org/Linux_2_6_32 KDE 4.4 This release uses KDE 4.4 by default as the KDE Desktop environment. KDE 4.4 offers new features such as PolicyKit 1, KAuth backend, and improved PulseAudio integration. In this release KNetworkManager is used instead of nm-applet. The KDE Desktop Live image is a downloadable CD you can use to test the new KDE environment with or without installing it. The image can be written to a CD, or to a USB flash disk using these instructions :cutesmile::cutesmile::cutesmile:
