How fast Ubuntu 10.04 will booting in 10 seconds !!

Ubuntu Linux distro developers have created a new blow with the performance booting Ubuntu. Ambition of Ubuntu Linux developers will be applied in 2010 to reduce the time booting up to only 10 seconds. The increasing adoption of Linux operating system device netbook has given spirit to the Linux developers to focus on the startup performance system in the netbook. Ubuntu 9.04 with the last month, also is one of the Linux distro that has this improvisation.

In the presentation in Barcelona, developer of Linux, Scott James Remnant revealed that the time booting Linux is reduced from 65 seconds at the 8.10 version of Linux, to just 25 seconds in Ubuntu 9.04. Canonical, vendor behind Ubuntu, will continue to add improvised time booting in Ubuntu 9:10 with the code name Karmic Koala. According to the claim Remnant, time booting Ubuntu 10.04 will changed to 10 seconds only, immediately following the release of Karmic.

Remnant information to give at the time which podići akan reduced. An important strategy to make Xorg display server running as soon as possible, so that will give you a short time for the components that must be placed before the start Xorg, including components udev device manager and initramfs, a temporary system files that are loaded to memory to facilitate syetm pross startup. Initramfs while acting as responsible for mounting the root file system and load the kernel module. In addition, the initramfs also play a role for software RAID, encryption disk, booting from the network file system, and perform other similar tasks. Remnant will reduce the time to reveal the performance of the two components above and eliminate some activities that can slow the startup.

Remnant says that the kernel and initramfs akan take 2 seconds, loading the drivers, mounting filesystems, and other load will took 2 seconds, launching Xorg display about 2 seconds and 4 seconds for the desktop environment and launching other services that are part of the user session . Computers will full load and is ready for use within 10 seconds, add Remnant.

  2. Then you must mount it in cdrom with this command :
  3. sudo mount -o loop ~/Desktop/ubuntu-9.04-alternate-i386.iso /media/cdrom0

Do you know Flex? Flex is one platform language to build web or desktop application from Adobe.

Flex is a highly productive, free open source framework for building and maintaining expressive web applications that deploy consistently on all major browsers, desktops, and operating systems. While Flex applications can be built using only the free Flex SDK, developers can use Adobe® Flex® Builder™ 3 software to dramatically accelerate development

~ Adobe

Flex builder was build to run in Windows and Macintosh only. But Adobe also hear some advice to make it on Linux. This tutorial show you how to install Flex Builder in your Ubuntu.
Flex Builder Linux is a plugin-only version of the Flex Builder that you can use to build Flex applications on Linux.

  1. Make sure Java common libraries in your PC was install the latest. To check this you can go to Synaptic Manager and find "java-common" then apply it. Thanks for insideria to remember me this.
  2. Go to Adobe web and download Flex Builder Linux Alpha and save in your home. You can download it here.
  3. Flex builder is a plugin in Eclipse, so you must have Eclipse first. You can search in Add/Remove Program and find Eclipse version 3.3.x or above.
  4. Run the installer either marking it as executable (chmod +x) or by using a shell to execute it (sh flexbuilder_linux_install_a4_081408.bin).
  5. Then you can start Eclise. You must create a new workspace before beginning. Select File > Switch Workspace from the menu bar and enter a new folder name. If the folder doesn't exist, Eclipse creates it.
