Toutiao, May 14: Top 10 new features of Leonora 11 Leonidas

Last year, we evaluated almost all operating systems in the industry, including fedora 10, Windows 7, UBUNTU 8.10, and open SUSE 11.1. The previous day we studied Windows 8 (Microsoft's next-generation operating system, or Windows 8) and Ubuntu 9.10, and this Round reached fedora 11. Its current code is Leonidas, it is expected to be officially released on March 13, May 26. The following are the top ten features of Leonidas. Let's start to discuss them.

 

Quick Start in 20 seconds

After Ubuntu 9.04 (codenamed jaunty jackalope) starts for 19.5 seconds, fedora 11 will achieve the same performance in any case. They claimed that the startup process could be completed within 20 seconds. The goal of fedora is to display the login screen within 20 seconds and complete the login as soon as possible. Speeding up task start and reducing disk I/O operations will be the key to Quick Start. for Readers interested in ubuntu9.04, refer to other articles on 51cto.com, for example, "come with me to try out Ubuntu 9.04 trial", "compare new experiences Ubuntu 9.04 desktop edition full contact", and "start my Ubuntu 9.04 only takes 14 seconds!.

To reduce the startup time, fedora 11 will remove setroubleshoot and several other bottlenecks. In addition, you can modify and edit the readahead behavior that affects the startup speed through editing/etc/sysconfig/readahead.

EXT 4 will become the default file system

In fedora 11, ext 4 becomes the default file system, which is different from Ubuntu 9.04. Is it necessary to migrate data from ext 3 to ext 4? I think so. Let's take a look at the benchmark test. For the processing capacity of large files (4 GB single file, write mode), you will see that ext 4 is far better than competitors, of course, ext4 is not only advantageous. If you are interested, refer to the article "Beware: ext4 may cause data loss" in 51cto.com.

 

EXT 3 has gradually become more popular in the Linux World. Ext 4 has more features, and its performance is generally better than ext 3. It has the following features:

◆ Better disk latency allocation and Memory Allocation

◆ Sub-second timestamps)

◆ Space preallocation)

◆ Journal checksumming)

◆ Large file support (> 2 TB) (this is essential ),

◆ Large file support (> 16 TB)

◆ Disk fragmentation support

Gnome 2.26

Gnome 2.26 brings some cool features that you will like.

◆ Comprehensive New Light Disk Burning: GNOME 2.26 introduces brasero, which can burn all kinds of CDs. Brasero brings many new features that were not previously available, such as audio track preview, audio track segmentation, integrity check, and cover editing.

◆ Simpler file sharing: GNOME 2.26 provides a plug-in for the file manager to conveniently share personal files through WebDAV, HTTP, and Bluetooth.

◆ Evolution has evolved and can be transplanted from Windows:

The most successful part of gnome 2.26 is here:

◆ First, evolution can now directly import the personal folder of Microsoft Outlook. The second is to support Microsoft Exchange's mapi protocol.

◆ Improved media players

◆ Pulseaudio with integrated volume control

◆ Supports multiple monitors and projectors. This is another wonderful feature of gnome.

 

◆ ECG-based communication: the Telepathy communication framework used by gnome has taken another step forward, and many features have been enhanced, such as file transmission, chat room invitations, voice themes and notifications, and enhanced VoIP experience.

◆ The gnome Web browser epiphany brings exciting new features and enhances the ability of the address bar. The fingerprint reader is integrated to improve keyboard operations.

Perhaps such a big fanfare still cannot express everyone's love for gnome, so please take a look at 51cto.com's "10 reasons for GNOME better than KDE.

KDE 4.2

KDE is also widely used by fedora users. KDE 4.2 provides many new features that have not been released before.

◆ Brand new and improved applets, including quicklauncher, weather information, news feeds, cartoons and quick file sharing. Plasma applet has been recognized by people.

◆ Kwin provides smooth and effective window management.

◆ Brand new and improved workspace tools increase productivity. Powerdedevil provides full support for Mobile Life and provides new power management for laptops and mobile devices.

◆ File management becomes faster and more effective. The doldolphin file manager now has a slider to easily resize the icon.

◆ Support for IMAP and other protocols has also been improved, and kmail is much faster.

◆ The Konqueror Web browser improves vector graphics support and improves many performance. Although fedora 11 has built-in Firefox 3.1.

◆ Many KDE applications can provide technical previews for Windows and Mac OS X. If you are interested, refer to 51cto.com's article on the Linux desktop software usage skills in KDE and learn about the differences between KDE and gnome.

Netbeans 6.5

Netbeans 6.5 is one of the most important updates of Fedora 11. Its main functions are improved as follows:

◆ Supports PHP Code Completion, xdebug, and network service functions.

◆ Javafx 1.0 supports animation, graphics, and Media Encoding and provides rich content application development.

◆ Added support for groovy and grails.

◆ Enhanced support for Javascript, Ajax, and Ruby.

◆ Provides automatic compilation and storage deployment for Java and Java EE applications.

◆ Enhanced database support: SQL history, SQL completion, result view, and editing improvements.

◆ Enhanced data binding support for Java me, SVG and creation of custom components.

◆ GUI builder: supports nimbus and simple class names.

◆ JUnit: supports a single test method.

◆ Debugger: re-designed the step into function.

◆ Netbeans IDE is intended for developers. From beginners to experts, everyone can find their own development tools, and we may also look at how the eight technical experts of 51cto.com commented on netbeans 6.5.

Thunderbird 3

Thunderbird 3 is now integrated in fedora 11.

◆ Archive: You can transfer emails from the inbox or other folders to the new archive folder system.

◆ Activity management: Activity Manager records all interactions between Thunderbird and your email provider in one place.

◆ Faster loading of IMAP information: thunderbird now downloads IMAP information in the background by default, so as to load information more quickly and better offline jobs.

Openchange

◆ Fedora 11 will contain the openchange library and use the mapi protocol to access the Microsoft Exchange server from the Linux client. To use this support in evolution, you must first install the evolution-mapi package.

UEFI/xfce 4.6

◆ The UEFI Specification defines a new model for the interface between the PC operating system and the platform firmware, providing a standard environment for starting the operating system and running the pre-start application.

◆ Xfce 4.6 provides a new configuration backend, a new configuration manager, and a brand new mix. Other core components of xfce have also been greatly improved.

Eclipse analysis tools

◆ Developers will be very happy. This is a very useful tool integrated by fedora 11. The target audience is various Linux developers. The first step is to use C and C ++ application developers.

GCC 4.4, RPM 4.7

◆ GCC 4.4 adds a new rewritten register distributor and a large number of other improvements, adding more command line switches.

◆ The new RPM remains unchanged, but there are still some noteworthy points.

◆ Faster upgrade.

◆ Some annoying bugs have been fixed.

◆ The handling of upgrade failures has been greatly improved.

Virtual identity authentication and console

The purpose of this feature is to improve the user experience of the virtual guest graphics console, providing accurate mouse pointer and higher screen resolution without manual configuration. Fedora 11 provides the ability to use the SASL protocol to authenticate VNC connections between KVM and qemu virtual machines. This new authentication method abandons the traditional VNC Password Authentication and fully ensures security.

Summary

It is too early to give a conclusion on fedora 11. However, with these important new features, we can foresee that fedora 11 will be a major release. Ubuntu 9.04 has achieved great success, and 9.10 will be released in October this year. In fedora 11, there was a lot of pressure. I personally don't have high expectations for it, because although it has made enough improvements, it still lacks enough motivation to drive people to turn to it. What do you think?
