Http://www.aliyun.com/zixun/aggregation/13835.html ">ubuntu is a free, open source operating system based on Debian, but has its own distribution (every six months release), user-focused, Easy to use ("usable" on the line) and promises 18 months of security upgrade support for each release. Ubuntu has the latest version of the GNOME desktop, with a large number of services and desktop applications, allowing you to experience a very comfortable operating environment with only one installation CD.
Ubuntu is a free software that gets it completely free. It also gives you the right to software freedom, which you should have heard about. But unlike other commercial distributions (such as Libranet, Lindows, Xandros, Red hat, etc.), the Ubuntu team believes that free software royalties should be free of charge.
Ubuntu does not have a very nice graphical installation interface, but it has a quick, easy interface. Well, although you need to understand the various settings for installation, the default settings fit most people. We compress the Ubuntu release into a single CD, but all the other software is available online. On a typical computer, the installation of Ubuntu should be done in 25 minutes.
The installation interface may not have a GUI, but you only need to use it once, because we will upgrade your systems and applications over the network. You do not need to reinstall your system at all, and you can upgrade it to each new release as you wish.
Ubuntu contains more than tens of thousands of software, but the core desktop installation system is merged into one CD, Ubuntu covers all the desktop applications, including word processing, spreadsheet programs to Web server software and development design tools. The above text comes from the Ubuntu official site.
The main changes in Alpha 1 are:
1, applications and software upgrades, many of which are automatically synchronized in the Debian unstable.
2, including the latest system core, based on 2.6.30-RC5 2.6.30-5.6 Kernel.
3, integration of the latest version of the desktop environment gnome 2.27.1.
4, the corresponding power management and notebook FN key to the bottom of the technology from the HAL to Devicekit-power and Udev-extras.
5, the new Intel Video drive architecture, accelerated from the existing Exa to the new Uxa, can solve the key performance problems in Ubuntu 9.04, but not as stable as exa, it has not been enabled by default.
6, the new default compiler GCC-4.4, in some places more stringent than GCC-4.3.
