Born in 1994, was wildly popular Red Hat Linux release in March 2003 released the 9th edition has been updated after they stopped. The end of 2003 came from the Evolution of Red Hat Linux Fedora Project, and now has grown nearly seven years. Fedora is Red Hat Linux to do seven years in mice, only mice has now grown into a tiger in the upcoming Fedora 14 release on the occasion, IT168 correspondents take you look for Fedora seven technology development process?

Red Hat Fedora Core is positioned as a testing ground for new technology, and Red Hat Enterprise Linux is defined as the stability of different priorities, many new technologies will be tested in Fedora Core, if stable, then it will consider joining the Red Hat Red Hat Enterprise Linux in. Fedora is expected to release 2 to 3 times per year of release.

Fedora up to now gone a full seven years, counting the upcoming November release of Fedora 14, Fedora has issued a total of 14 versions, each new release, developers will always bring a lot of surprises, Even Linux creator Linus also use and maintain Fedora operating system, ranked third in 2010 the global supercomputer Roadrunner (Recommended article: vs. peak: the world's most cattle 3 Linux supercomputer) is also using Fedora operating system.

IT168 editors collected these seven years to publish the Fedora 14 release some of its technical features, although for now, a lot of versions of the so-called out of the new features is long overdue, but he was a worthy of applause is in terms of progress, Reviewing the Old is an eternal learning experience, I believe that the technology review process under Fedora is a good choice.

Fedora Core 1

Red Hat user for Red Hat Linux 9.0 will not be unfamiliar, it can be said that it released the final version of a desktop. In fact, Red Hat Linux desktop system is far from over, it is in fact another way in the development.

Red Hat released a new open source community project called Fedora. The Fedora Project and Red Hat similar to the Sun StarSuite and OpenOffice.org, Netscape and Mozilla relationship. Products introduced by the Fedora Project is no longer based on Red Hat Linux 10 or other similar name, it will not make commercial retail version sold in the market. In other words, Red Hat no longer supports the product with any commercial support.

The Fedora Project released the first product is Fedora Core 1 (2003 Years 11 officially launched), we can be "as" is the Red Hat Linux 10 (though Red Hat does not think so). Although Fedora Core 1 is the first version, but one has also been introduced a lot of sought after, regardless of function or from the installation have made a good reputation. Following the review the next version of the installation process it.

Installation process easier

Linux gives the impression that installation has been difficult, but the Fedora Core 1 installation process is very "approachable", as opposed to Red Hat Linux 9.0, even more humane.

Tips are ready to install CD-ROM

Fedora installer started copying files, will be based on the selected installation mode, which will be ready to prompt the installation CD. This is a very thoughtful design, shown in Figure 1.

▲ Figure: What prompted the installation CD ready

Have a stronger graphical installation support

In addition to supporting Fedora installer CD mode, NFS graphical installation mode, it now supports HTTP, FTP graphical installation mode. HTTP, FTP mode using the default text mode installation, you need to add graphical boot time parameters to open the graphical installation. But note that, HTTP, FTP graphical installation mode need to consume about 64MB of memory resources, if the machine is "old car" configuration, then he uses the text mode installation as well.

Simpler firewall settings

During installation, Fedora Core 1 firewall settings screen easier than previous versions, simply select "Enable firewall" or "no firewall" option, shown in Figure 2. It is very easy for beginners to master.

Chinese complete installation tips

Throughout the installation process, Fedora Core 1 for Chinese support is even better, not only in the graphical installation mode, you can use the Chinese, in text mode can also be a good indication of Chinese instructions. Although Red Hat Linux 9.0 can also display Chinese text-mode instructions, but there are a lot of screen or "residual" English instructions, such as the package group selection. The Fedora Core 1 installation program, you can say that it is the Chinese show, shown in Figure 3.

Abolished the LILO boot manager

We all know, Linux has two well-known boot loader manager: LILO and GRUB. However, due to backward technology LILO, modify LILO configuration file each time, you must re-install LILO. So, Fedora Core 1 officially canceled LILO. During the installation process, we simply choose to use or not use the GRUB boot loader, shown in Figure 4.

▲ Figure 4: No LILO boot manager options

More beautiful desktop environment

Linux in addition to free, stable, high-efficiency advantages, they have a dazzling graphical interface is also one of its strong selling points. To run on Fedora Core 1 on the graphical interface there are several, such as GNOME, KDE and TWM, etc., but the most common, best thing is to calculate the GNOME and KDE, its powerful features, flexible configuration, the interface for ultra-mysterious Windows XP also eclipsed.

Fedora Core 1 desktop background looks elegant, the use of a relatively new version of GNOME 2.4 and KDE3.1.4, relative to the style of the entire desktop Red Hat Linux 9.0 some more beautiful, as shown in Figure 5.

Fedora seven storm Road: look for the footprints of 14 versions

Figure 5: Fedora Core 1 desktop

Graphical boot process

Fedora Core 1 of the more fancy splash screen, and Red Hat Linux 9.0 and other older versions, Fedora Core 1 is no longer displayed when starting a detailed startup information, instead of using the graphical boot mode, shown in Figure 6. This is somewhat similar to the Windows startup mode to start the information hidden. For some beginners, see the full screen flying letters, to a certain extent, reduce the fear of Linux.

Figure: graphical boot mode

But for the "old bird" who is still hoping to return to their original state. It's very simple, you can modify the system's / etc / sysconfig / init file:

(1) First switch to another virtual console (if the current in the X-Window environment, you can press "Ctrl + alt + F1", "Ctrl + alt + F2" and other key combination to switch).

(2) and then use the root account, password system, use vi editor to open / etc / sysconfig / init file. Find one of the "GRAPHICAL = yes" line, shown in Figure 7, the yes to no to.

Figure 7 modified / etc / sysconfig / init file

(3) Finally, wq! Command to exit vi editor and save. On the next start, on the back to the original state it!

Wealth of Linux applications

Linux distributions and Windows versions differ from commercial, not by all publishers to develop their own components, each component is independent of the open source project for the development, testing, and Red Hat and other Linux distributors are responsible for testing , integration, including kernel and application components, to form Linux distribution.

Launched last November as the new Linux distribution, Fedora Core 1 integrated more, newer and more stable applications, including office, multimedia, graphics, entertainment and services suite.

The only regret is that, Fedora Core 1 kernel does not use the latest 2.6 kernel version, but added a lot of very useful tools: such as gpdf (GNOME PDF document viewer under), rhgb (mentioned earlier Fedora Core 1 graphical boot package), yum (and dependence testing tools maintenance package) and other important tools.

The Red Hat Linux is famous as an integrated configuration tool redhat-config- ××× ( ××× that specific configuration item name), where in Fedora Core 1 has also been strengthened, a new addition such as redhat-config-boot (graphical boot manager configuration tool), redhat-config-netboot (start the graphical network configuration tool) and other configuration tool, shown in Figure 8.

Figure 8: New integrated configuration tool

Red Hat Fedora has inherited the mantle, but compared to the original Red Hat Linux, Fedora Linux is more able to reflect the spirit, after all, it is a completely open source community sponsored by the Linux distribution project. In fact, Fedora Core 1 in terms of speed, interface, or integration software performance, as opposed to Red Hat Linux 9.0 has a lot of progress. It can be said, Red Hat has not abandoned the desktop operating system, but stripped of their products and services, in fact, the development of the Linux world this is a major trend.

Third Edition: Fedora Core 3

Code: Heidelberg (Germany, a city name. Is also a beer brand)

Release Date :2004 -11-08

Fedora Core 3 began at the popular ext3 file system provides a kernel and e2fsprogs support. Core 3 for the desktop users to do some care, to provide a remote VNC desktop, printing enhancements. Fedora update for each version will fix this bug and generally upgrade their packages. Fedora Core 3 version of the desktop environment to upgrade to GNOME 2.8, KDE3.3.0 and OpenOffice.org 1.1.2. In addition, the version using the 2.6.9 kernel.

Fedor from the first version allows the user to use the RPM package manager to automatically update the Linux system. From Fedora Core1 and 2 version, there is a lot of user requirements to improve system speed and resource utilization, user requirements development team should be upgrading the system, Fedora Core 3 version will be faster than 40%.

Here are some of Fedora Core 3 new features:

File selector

In Fedora Core 3, further complete the GTK + file selector. For example, improved type-ahead search function, so you can just type a few characters, the system will automatically search for the file containing the input character. Results as shown below. When you need to find a path of the file, you can also use the keyboard "/" to separate the lower-level directory. Although this path to the file that way for now very common, but at the time was a breakthrough.

The most popular feature is achieved through the SpamAssassin spam filter, simply click on the button will start the garbage scanner.

Compilation tools: GCC4.0

Fedora Core 3 is a major breakthrough in the first Linux distribution to add GCC4.0 (GNU C Compiler) development platform. At that time GCC3.4.2 is still the mainstream version, Fedora Core 3 version of the first to upgrade to GCC 4.0. GCC4.0 improve the static single assignment (SSA) executive function, SSA simplify and optimize the compiler for the handling of variable properties.

Fourth Edition: Fedora Core 4

Code: Stentz (a French wine brands)

Release Time :2005 -06-13

Fedora Core 4 on the desktop using the then-new Gnome 2.10/KDE 3.4. Fedora Core 4 offers a called Global File System (GFS) of the open source cluster file system, and begin using the built-in Xen virtualization. GFS file system on a RHEL 5 which is officially referred to as Red Hat Enterprise cluster to achieve, but also the Xen virtualization system after RHEL 4 update to get some support, and officially became a RHEL 5 virtualization technology is an important part. In addition, Fedora Core 4 PowerPC architecture processors began to provide support.

▲ Figure: Fedora Core 4 Screenshots

Fedora Core 4 operating system is based on 2.6.11 Linux kernel, it did specifically optimized for the Pentium 4 processor. However, it can also 400MHz Pentium II, even if the user happy, only the text interface in low-configuration running on the machine. Fedora Core 4 the recommended memory, 32-bit x86 systems, preferably with 256MB of memory, 64-bit x86 systems should have 512mb memory.

Important function of Fedora Core 4 Updates

Boot time was significantly shorter

Fedora Core 4 is the most significant improvements in boot time, just 55 seconds, users can boot from the GRUB menu to the graphical login screen. Fedora Core 3 with 1 minute 40 seconds compared to significantly reduce the waiting time, and GNOME's startup time is only 16 seconds, lower than the version of Fedora Core 3 for 27 seconds. In addition, like OpenOffice.org, Firefox and Thunderbird and other software start-up time are significantly reduced.

Desktop GNOME2.10

Fedora Core 4 uses Gnome2.10 graphical desktop software version and KDE3.4. It is a PDF file reader installed Evince and OpenOffice.org2.0 software. In addition, it contains the GFS software. Thanks to the help of Fedora Extras project, Fedora is becoming increasingly sophisticated, Fedora absorbed from external software includes: Abiword word processor, XMMS media player, Gnumeric spreadsheet and the Freeciv game.

Using Fedora Core 3 users will notice GNOME2.10 new menu bar at the top. Previous version of GNOME applications and operating menus using two separate menus, and use the system GNOME2.10 three top-level menu: application, location, and the desktop. Application menu is mainly run the program, allows users to enter the exact command to start the appropriate application. Location menu allows users to connect directly to the home directory or desktop file, install the removable devices, network servers, etc., can also search for recent documents. Desktop can be connected to sub-menu (configure desktop settings), for the system settings submenu (configure system resources), can also be locked off the screen and access the help documentation.

GNOME default ClearLooks new theme, this theme is very pleasing, functional subject classification clear. However, some new windows and tabs icon is not particularly clear, especially without text labels. However, users can download from the site FireFox theme "Qute" to resolve the issue.

On Fedora Core 4 in multimedia applications (video transmitters) and Juicer Sound (CD extractor) officially became part of the GNOME desktop system. However, due to copyright issues, Fedora Core 4 can not support the MP3 format music.

OpenOffice.org 2.0

Fedora Core 4 uses the OpenOffice.org 2.0 version. The new version of Openoffice to use the default standard OASIS OpenDocument XML. This version has better flexibility, the use of vendor support for the OpenDocument format, while still compatible with KOffice.



OpenOffice.org 2.0 also improved with the Microsoft Office interoperability. Many of Microsoft Office documents can be directly converted to OpenOffice.org format. Use OpenOffice.org 2.0 can open Word and Excel documents, and in order to enhance compatibility with Excel spreadsheets, OpenOffice.org 2.0 can support up to 65536 lines.

In addition, OpenOffice.org 2.0 also adds a new database set up, basically OpenOffice.org 2.0 users can call the built-in system in Java-based HSQL database or other external databases (such as ADO, Microsoft Access, MySQL) in data to create, modify and query form. Some of the wizard can also perform complex SQL constructs statements interleaved data in the database.

Although the package management has been a Fedora Core operating system weaknesses, and in Fedora Core 4 version is also still not well improved. However, the continued efforts of the team under Fedora, Fedora Core 4, or upgrade a lot of packages, which have GNU GCC 4.0 editor, Eclipse IDE (GCJ compiler), PHP 5.0.4, Perl 5.8.6, mod_perl 2.0, and many other Java project components.

Fedora Core 5

Code: Bordeaux (France a rich wine area and has a cartoon character.)

Release Date :2006 -03-20

Fedora Core 5 development cycle, with nine months of time, and the Fedora Core 5 Logo from officially opened.

Figure: Fedora Core 5 beautiful interface

Desktop improvements

Fedora Core 5 for the desktop to join the new Rendering Project (Graphics Rendering), the new package management tool Pirut, multi-language features such as SCIM support frames. SCIM language input framework provides easy to use interface, you can enter a variety of non-English languages. SCIM replaces IIIMF system used in the past. SCIM in the later period of time as the various Linux distributions default Chinese input methods, including Ubuntu and RHEL.

Fedora Core 5 using the default web browser Firefox 1.5, it has a lot of new features, faster, safer and more effective. At the same time using the OpenOffice.org 2.0 version, a lot of the upgrade package, making the performance and efficiency can be improved. Fedora Core 5 using the gnome-mount replaced the fstab-sync, for more effective mechanisms to deal with HAL to mount and use.

Management and development improvements

In Fedora Core 5 system configuration tool for Xen virtual machines now use a standard graphical installation process, running on the desktop as a window procedure. Fedora developers also created a gnome-applet-vm, which is a simple virtual host monitor applet, and libvirt software library providing an API to use the Xen virtualization capabilities. In addition, it also provides a new system monitoring tool SystemTap (a debugging and analysis tools for system bottlenecks) and Frysk (an implementation of analytical techniques that can monitor the running processes or threads).

The anaconda is the industry leader in the further development of the system. New features include remote login, as well as enhanced support for backtracking. Install the system by the yum package manager to achieve. This enhancement is the Fedora Extras into the first step in the installation process.

Use at industry-leading Apache HTTP Server version 2.2, this version provides authentication, database support, proxy and content filtering enhancements.

System Level Changes

Fedora Core 5 uses is based on the Linux 2.6.16 kernel, and includes X.org X11R7.0, R7.0 new modular structure so that the drive to upgrade and develop more simple, graphical interface to Linux quickly onto the road improvements. Compiler is used on gcc 4.1, which makes the system all of the packages use the new compiler construction, safety and performance have improved. Also, for laptops and mobile devices PCMCIA framework has changed, the old version of pcmcia-cs package using the cardmgr / pcmcia services in Fedora Core 5 version, they are replaced with new pcmciautils package, PCMCIA device directly handled by the hotplug system, and uses dynamic udev subsystem. Thus, system efficiency and performance have improved.

The SELinux implementation has undergone tremendous changes, switch to the light (reference) strategy. Reference to policy support binary policy modules. SELinux policy will move to separate package as possible, the user can more easily customize the specific strategy. This version also supports SELinux framework of MCS (Multi Category Security, multi-class security, enabled by default) and MLS (Multi Level Security, a multi-level security) subsystem. SELinux continues to support the TE (Type Enforcement, the type of force, enabled by default) and RBAC (Role-Based Access Control, Role-based access control).

Fedora Core 6

Code: Zod (DC Comics universe of a cartoon character. Is a record company name)

Release time :2006 -10-24

Fedora Core 6 desktop and major improvements in performance, rebuild the application software through DT_GNU_HASH known to enhance the performance of 50%. Fedora Core has been using the Anaconda installation tool support system began to upgrade the repository, and supports IPv6. Fedora Core 6 in the application (such as: OpenOffice.org) started to achieve significant performance improvements. In addition to the previously supported x86, x86-64 and Power PC chip architecture, the new version also supports Intel-based Mac systems. In addition, Fedora Core 6 also introduces a new GUI virtualization manager.

Figure: Fedora Core Interface

In the installation program (installer), the new version of one of the major improvements is to allow the user to install a network access functions, such as some third-party RPM repositories (eg: Fedora Extras), or local resources. This change is quite simple - you can have more choices. Compared with the previous version, the new Fedora installation is now more customizable.

Desktop area

Fedora Core 6 continues on the desktop font and attractive interface to make progress at the same time, in terms of functionality, integrates the latest releases of GNOME and KDE features. Specifically, Fedora Core 6 desktop improvements include: a new set of standard desktop platform to enable GL-accelerated effects, better and faster software updating tools and the latest version of the popular open-source application.

Fedora's internationalization enhancements include: multi-language support and input switching tool. Overall, Fedora's major primary components are now translated into 50 languages, mainly by volunteer contributors.

Performance

Fedora Core 6 in terms of performance enhancement is built on the original underlying systems. Applications (such as: OpenOffice.org) re-start acceleration is achieved with DT_GNU_HASH. This function is optimized for speed and data cache access is optimized. Another major performance optimization is the Network File System (NFS) aspects.

System Management

Fedora Core 6 in both underlying and interactive parts of the administrator's experience has been optimized and enhanced. A major improvement is the installation allows administrators to specify external resources. Although it has long been available from a local or specific network location to install, but Fedora Core 6 to allow a third party during the installation process, select the installation package resources. Because it contains the Fedora Extras repository, so installation of Fedora Core and Fedora Extras package division becomes less strict. These installation improvements, coupled with package dependency and updating tools to improve, make it easier to manage systems.

In addition, the GUI management tools, new content includes: a virtualization manager, an SELinux troubleshooting tool and an improved LVM cluster management tool. Smart card services by the new CoolKey technology. In addition, the system in other improvements include: support for IPv6, and a 2.6.18-based Linux kernel that automatically detects and configures the number of processors on a machine.

Fedora 7

Code: Moonshine (a record company's name. Is the name of a movie)

Release Time :2007 -05-31

Fedora 7 started, Red Hat is the "Core" and Community "Extra" repository integration. Version 7 also the first time, the Gnome desktop, KDE desktop, point system different Live CD, and desktop, workstation and server versions separately produced a different spin. It has also become a Fedora release after the convention.

▲ Figure: Fedora 7 boot screen

This release includes many key components and technologies of the new version:

Spins (Spins)

First time, Fedora includes several different sets (spins), which is the set of software packages based on variations of Fedora. Each spin has a combination of software to adapt to different user needs. In addition to the network installation using a small boot.iso image, users have the following choices:

* Based on GNOME and KDE desktop environment, bootable Live images that can be installed to the hard disk. These spins are installed for the media want to use a single desktop users, can also be used with friends, relatives, sharing and use in the assembly.

* A regular image for desktops, workstations and server users. The release set for the last version of Fedora users with a good upgrade path and similar environment.

* Consisting of images from the DVD release set that contains all of the Fedora repository software. This major release set for users without broadband internet access, you need to install all the software on CD-ROM.

Desktop

This release includes GNOME · 2.18 and KDE · 3.5.6. Integrated Fast User Switching. Developer releases by ConsoleKit and full integration to provide this functionality. By using Xorg 1.3 version, the display can be hot-swappable and auto-identification and application.

In wireless network applications, Fedora 7 release also provides a number of firmware packages (firmware), for wireless networks. NetworkManager presents a graphical interface that allows users to wireless / wired network to quickly switch between, for increased mobility. NetworkManager in GNOME and KDE Live environment is installed by default.

In the window interface, Fedora 7 includes a new "Flying High" theme, which is the Fedora art (Artwork Project) project and the wider community of the tireless efforts of some of the results.

In the browser, Fedora 7 using the Firefox 2 version, this version offers a host of new features, including online spell checker, built-in phishing protection, and the ability to resume browsing sessions.

The input law, Fedora using I18n support is much improved, SCIM installed without any configuration. SCIM can handle nearly every alphabet / set of characters. Environment through the GNOME Live language packages and input methods, Fedora can be applied to a wider audience.

For the new SELinux graphical management tool system-config-selinux is installed by default. system-config-securitylevel SELinux in switch setting is removed and moved to this tool. And diagnostic tools setroubleshoot the default SELinux Open. This tool for desktop users access denials by SELinux notification and detailed information, and how to deal with their recommendations.

In addition, Fedora 7 kernel contains new FireWire (FireWire) protocol stack, device management is more stable. And also improved power management, the kernel contains a dynamic ticks to achieve.

In short, this release will be dictionaries used by desktop applications for a part of the integration, which provides a consistent desktop experience while saving resources.

System Management

Virtual machine with Fedora's graphical virt-manager management tools integrated core virtual machine technology (KVM). KVM provides a full virtualization solution. In this release users can KVM, Xen and Qemu, freedom of choice.

Fedora 7 includes Xorg 7.3, KDE 3.5.6, GNOME 2.18 and Linux kernel 2.6.21, which is the latest open-source desktop software system, abandoned the traditional nomenclature of the core, and by default contains the core and external components, Fedora This is a new milestone in the evolution, but also shows the number of desktop software is inextricably linked with the Fedora now has released the official website of the relevant page, ISO file available for download, and BT has become the official distribution methods.

Xen virtualization technology in addition to outside, Fedora 7 also includes important features Kernel-based Virtual Machine (KVM) and Qemu virtualization technologies. All of these are available through the Fedora graphical virtualization manager for implementation.

Fedora 7 release also marks an important milestone, Fedora's emergence as a leading community-driven project. Previously maintained only through the Fedora kernel Red Hat engineers, the maintenance of the corresponding Fedora Extras is the community members. Fedora 7 abolished this distinction, the new single Fedora repository for Red Hat's engineers and community members is as accessible, to give communities more of the right to modify Fedora.

Fedora 8

Began to support the full Fedora 9 Live USB technology, and Ext4 file system for the first time as an option. Ext4 was not stable, but has also been shown to replace vague Ext3 trend. Ext4 in RHEL 5.3 as a technology preview option appears in RHEL 6 will also be a default file system option. Fedora 9 also introduces support for encrypted file systems eCryptfs.

In addition, because the performance of IcedTea in Fedora 8 was unstable, Fedora 9 and replaced with OpenJDK 6.

Fedora 9 also has other performance improvements, such as:

1 support EXT4 and Encrypting File System.

2 can now use Jigdo download and install media.

3 support Gnome 2.22, KDE 4.0.3 and Xfce 4.4.2.

4. Readjusted during installation to support ext2, ext3 and NTFS partitions.

5 The default installation of open source Java development environment OpenJDK 6.

6 support Openoffice.org 2.4 and Firefox 3 beta 5.

Fedora 10

Code: Cambridge (the United States a city name is the name of a battleship U.S. Navy)

Release time :2008 -11-25

Fedora 10 Connection Sharing enabled, wireless, and further enhance the support of the printer. And more flexible software management libraries RPM, and better audio, camera and infrared remote control support to the desktop more user friendly.

▲ Figure: Fedora 10 installation interface

Some critics said the performance of Fedora in 2007 fell into the lowest point in history, in particular, this version of Fedora 9 Sulphur is an unprecedented failure, resulting in a large number of users have switched to Ubuntu and OpenSUSE release of these two. But after the release of Fedora 10, this bad situation has improved gradually.

Key features of Fedora 10

1. RPM Fusion

Fedora has long been criticized because they do not provide patent codec (codec), for familiar reasons. In the past, through various third-party repositories to get these extra software is prohibited, but basically they are often associated with Fedora software repository software conflict, or is not compatible with each other. In the Fedora 10 release, several of the most commonly used software will be integrated with the warehouse, creating a new super-repositories - RPM Fusion, but this super-user access to the software repository is multimedia codecs and hardware drivers are only required Software warehouse

RPM Fusion is the most remarkable features of Fedora open, they use the same tools (such as packaged software) and the same packaging process, each package their software, so the quality is guaranteed.

2. Better printing support

In Fedora 8 the printer automatically configured as possible. Into almost any printer, all missing drivers will be automatically installed, users do not need the whole process yourself. In Fedora 10, the printer control applications, system configuration print driver, have been completely rewritten and simplified writing. Of course, some changes are very small, it is these small changes the whole printing system is a face-lift, some significant improvements include:

* No longer need the root password when prompted for the root password

• There is no paper, printing tasks, and so rejected icon

* Print task fails to notify the user, and provide diagnostic tools to identify the reasons for failure

* Dialog has been simplified, no longer feel confused

3 Better remote control support

Like to use your computer to watch movies or listen to music? Want to use your remote to control these applications do? Fedora10 contains gnome-lirc-properties package, which allows remote configuration and add a new easier, it also allows users configure their custom remote control key events. Based on this characteristic of the development work was reintroduced, not just gnome-lirc-properties, but also includes other popular applications to ensure that they work under the letter of the normal configuration tool.

4 better and faster start-up

Fedora 10 includes a number of significant improvements in its startup process. Started from the system just started, users will notice no longer Grub splash screen, the system starts the whole process of saving time, while removing some of the screen flashing images, so start the process even more refined. For those who want to enter the boot menu of the user, as long as the system boots do not hold any key release, the boot menu will appear.

Grub loaded, users will notice RHGB disappeared. It has been a new program replaced Plymouth, Plymouth advantage of kernel-based mode setting, so start the process is no longer flashing, a smooth transition to the GDM, and provides a better graphical interface. This is not only beautify, Plymouth does not require a separate X server to run, so this allows the system to improve the startup speed greatly improved.

In addition to the features, look at other work being developed to reduce the boot time, including pre-read function is enabled by default, it starts to use a parallel system, not only these. In short, many users of the system should be able to see them start faster.

5 Connection Sharing

This feature will be a hacker conference in the world is very popular, Connection Sharing allows users to more easily set up a wireless ad hoc network, all traffic will be via an additional connection - the preferred connection, such as the second WI-FI card , 3G data connection, or pure Ethernet connection.

This feature has been in Fedora 9 has been developed out of the 3G network card out of the box functionality, including under the Network Manager allows multiple network devices.

Network Manager of the improvements and more than that, many users complained when the wireless network connection, there are more significant speed increase. It looks and Mac OS X is almost under the Airport connection.

6 first aid kit

"First aid kit is an automated recovery tool, which is normal recovery process and achieve the combination, and apply them to the system. First aid kit deal with the recovery process with plug-in A plug-in system responsible for a specific part of the , like Grub, init code and the X server. first aid kit is designed to automatically fix the focus on maintaining user data integrity problems. In other words, first aid kit will try to fix the system errors, and you have ability to recover these errors change. "

7. Defect Audio

"PulseAudio sound server has been rewritten, replacing the traditional interrupt-driven approach, replaced by a timer-based audio scheduling, which is another system, such as Apple's CoreAudio and Windows Vista sound subsystem using the approach, There are many advantages, not only to a minimum to reduce power consumption, to minimize the disruption, flexible adjustment potential application needs. "

8. Sugar Desktop

Throughout, Red Hat and Fedora and OLPC project has been close co-operation. Currently, to help gain wider attention and use of innovative effort, focused on children's Sugar desktop environment (the kids prefer, we all say), Fedora Project members hard work and some practical activities package , so you can more easily on your Fedora system to use them.

This is a very good way to participate in the development of this project, more activities have been in the package came. If you want to try, you need to do is install the Sugar desktop group. If you want to help develop, please click to see this wiki page.

9. Improved codec support

This feature and the advent of convergence RPM Fusion well, increasing dependence GStreamer additional time will be limited directly to the decoder, as long as the player needs. If the user opens the PackageKit RPM Fusion, it will automatically find and install your currently playing media files the appropriate decoder.

10 Better webcam support

Hans De Goede has been very hard to ensure the development of a camera if there is a Linux version of the driver (for most cameras, the driver does exist), for Fedora out of the box. Previously, the camera can not get good support, not only because the driver is not included in the kernel, but also because they use V4L2, and many applications only and V4L1 compatible. Now, more camera driver is included in newer kernel, and a lot of random and confidential application and driver compatibility.
