Microsoft really scared about Ubuntu 9.0.4 - Ten reasons

The following ten reasons are made to get scared Microsoft about Ubuntu 9.0.4

1. It is launched three different colors (Desktop, Server and Netbook)

2. It supports ext4. Even Redhat people are doing research in ext4 to implement in that. But Ubuntu 9.0.4 did it

3. It supports ntfs file system in a fastest manner.

4. It is user friendly like Microsoft Windows.

5. It boots 21.3 seconds in normal systems.

6. 4 GB Disk space and 256 MB Ram is sufficient to run this effectively.

7. Online updation and upgradations are available.

8. VLC Player support which is used to play almost anyfile format can be updated easily through internet with this.

9. Wine can be installed for accessing MS-Office and other exe formats.

10. It can be installed by using 1GB USB stick memory with 384 RAM in atom processors which netbooks won't have DVD drives usually.

Ubuntu 9.0.4 64 bit edition works good

Recently I downloaded Ubuntu 9.04-64 bit edition from the torrent site. It really works good. I want to share the torrent link with you. If you install this in ext4 format, It will be faster than the operating system that is installed by ext3 format file system. It boots in 21.3 seconds approaxmately as per the latest Ubuntu forum which sounds great now. It will be able to handle fastly files which is upto 16 terabytes.

Converting ext3 to ext4

It is possible to mount both ext3 (and ext2, in kernels 2.6.28 and later) filesystems directly using the ext4 filesystem driver. This will allow you to use many of the in-core performance enhancements such as delayed allocation (delalloc) and multi-block allocation (mballoc), and large inodes if your ext3 filesystem have been formatted with large inodes as is the default with newer versions of e2fsprogs. Simply mounting an ext3 (or ext2) filesystem with a modern (2.6.27+) version of ext4 will not change the on-disk structures, and it is possible to revert to the ext3 (or ext2) driver should there be any problem with ext4. If you plan to use the ext4 driver to boot from an ext2/3 partition, and you compile your kernel without the ext2/3 drivers, you may need to add rootfstype=ext4 to the kernel command line.

In addition to the in-core performance enhancements, there are additional features which modify the on-disk format from what ext3 understands, such as extents, which can significantly improve the ext4 filesystem performance, but mean the filesystem cannot be mounted by kernels that do not support ext4. There are additional ext4 features, such as flex_bg and > 16TB filesystem support that can only be enabled at format time via mke2fs.

To change an ext2 filesystem (should you still have one) to ext3 (enabling the journal feature), use the command:

# tune2fs -j /dev/DEV

To enable the ext4 features on an existing ext3 filesystem, use the command:

# tune2fs -O extents,uninit_bg,dir_index /dev/DEV

WARNING: Once you run this command, the filesystem will no longer be mountable using the ext3 filesystem!

After running this command, you MUST run fsck to fix up some on-disk structures that tune2fs has modified:

# e2fsck -fpDC0 /dev/DEV

Notes:

• by enabling the extents feature new files will be created in extents format, but this will not convert existing files to use extents. Non-extent files can be transparently read and written by Ext4.
• If you convert your root filesystem ("/") to ext4, and you use the GRUB boot loader, you will need to install a version of GRUB which understands ext4. Your system may boot OK the first time, but when your kernel is upgraded, it will become unbootable.
• WARNING: It is NOT recommended to resize the inodes using resize2fs with e2fsprogs 1.41.0 or later, as this is known to corrupt some filesystems.

Ubuntu 9.0.4 Supports Ext4 file system

Ubuntu is really doing good in the matter of launching new ideas very soon in implementation. They implemented ext4 file system in the latest operating system Ubuntu 9.0.4. Recently the Fedora live CD is launched for its latest edition. But it really has Ubuntu in the backend. So the system engineers are really thought that there will be only three operating systems which will be expecting to occupying the desktops and netbooks (laptops) in the future. Those will be as follows:

1. Windows

2. Ubuntu

3. Chorme (the upcoming Operating System which is going to be launched by Google)

Ubuntu 9.04 is launched

This time three different versions has been launched by Ubuntu. (i.e., Ubuntu 9.0.4)

1. Desktop Edition

2. Netbook Remix Edition - for small screen netbooks

3. Server Edition

Requirements for Desktop Edition:

• A blank CD and the ability to “burn” blank CDs
• A modern Intel or AMD compatible computer
• At least 256MB of RAM

Bare Minimum requirements

It should be possible to get Ubuntu running on a system with the following minimum hardware specification, although it is unlikely that the system would run well. You should use the Alternate install CD to attempt such an installation.

• 300 MHz x86 processor
• 64 MB of system memory (RAM)
• At least 4 GB of disk space (for full installation and swap space)
• VGA graphics card capable of 640x480 resolution
• CD-ROM drive or network card

Recommended minimum requirements

Ubuntu should run reasonably well on a computer with the following minimum hardware specification. However, features such as visual effects may not run smoothly.

• 700 MHz x86 processor
• 384 MB of system memory (RAM)
• 8 GB of disk space
• Graphics card capable of 1024x768 resolution

• Sound card

• A network or Internet connection

Note: All 64-bit (x86-64) PCs should be able to run Ubuntu. Use the 64-bit installation CD for a 64-bit-optimised installation.

Recommended for visual effects

Visual effects provide various special graphical effects for your desktop to make it look and feel more fun and easier to use. If your computer is not powerful enough to run visual effects, you can turn them off and will still have a usable Ubuntu desktop.

Visual effects are turned on by default if you have a graphics card which is supported. For information on supported graphics cards.

• 1.2 GHz x86 processor
• 384 MB of system memory (RAM)

• Supported graphics card

Netbook remix Edition Requirements:

Before writing your flash, it is highly recommended that you verify the md5 sum (hash) of the .img file. For instructions, please seeHowToMD5SUM. For the current list of Official Ubuntu MD5 hashes, see the MD5SUMS file for the release you're using underhttp://releases.ubuntu.com (and optionally the PGP signatures in the MD5SUMS.gpg file), or see UbuntuHashes. This ensures that the file was not damaged during the download process and is 100% intact.

Bug in RHEL5

Consider the scenario:

1. You configure the PXE installation server in Redhat Enterprise Linux 5, which includes DHCP server, DNS server (Purely optional), TFTP server, NFS server and other package dependancy services (like xinetd) in one machine. Remember that you have to copy the entire DVD to the NFS location which is usually /var/ftp/pub.

2. Disable the IPtables (for newbies) or Post some specified IP Table rules which provides access for the port number 69 (tftp) (for advanced users), check in the client machine for installation.

3. Then Configure YUM server with the same /var/ftp/pub path, which has to use the same set of rpms.

4. You will get the bug, when you again use the installation server. It means that you can not use the same installation server path for YUM server. 

It is the bug in RHEL5.
