Linux – Speed up your filesystem by upto 50 %

Nov 9

Gepostet von admin in Linux | 2 Kommentare

Every time a file is read from your Linux ext3 partition it writes back a attribute to the file detailing the last access time. There are very few programs that actually use this to operate and it slows everything down.

Disabling atime and diratime on your Linux ext3 file systems can improve disk performance up to 40%!

WARNING: If you are using programs such as tmpwatch, mutt, or mail-notify this configuration change could cause those programs that make specific use of atime not to work.

  1. Start a terminal.
  2. Switch to root using the “su -” command.
  3. Backup your fstab – “cp /etc/fstab /etc/fstab.old”.
  4. Open your /etc/fstab in the editor of your choice (nano, kate or gedit recommended). This can be done by issuing the command “nano /etc/fstab”, “kate /etc/fstab”, or “gedit /etc/fstab”.
  5. Locate the partitions that contain your / and /home file systems, as well as any other file system you want to optimize. Examples include /dev/hda2 and /dev/hda3, or /dev/sda2 and /dev/sda3.
  6. In the fourth section (just before the two numbers at the end of the line) you will see the options section of the fstab.
  7. Enter “,noatime,nodiratime” after the existing options for each partition you wish to optimize.
  8. Save the fstab file.
  9. Reboot.

Enjoy your newly optimized Linux ext3 file system.

Sep 19

Gepostet von admin in Linux | Keine Kommentare

Ideally installation of Windows should be done first.This gives you an advantage of not having to format your NTFS later when you install ubuntu as you can leave that space the first time when you install Windows.

1) Back up your system.

  • If you are installing windows the first time you can skip this step.
  • If you have windows installed make sure you backup every folder and data that is important and burn them to disks or even move them to external drives.
  • If you do not have a windows recovery tool now is the best time to acquire it before you proceed further.It is important that you have a recovery tool.Not that it is necessary but it never hurts.Clean out all the partitions on your computer by backing up the important data on external disks/ hard drives and then delete everything from your computer.
  • Make your hard drive as clean as you can. Uninstall all the unnecessary programs from the computer.( This step is not required but it is advisable.)

2) Resize using windows Vista ( You can either do this or skip to step 3)

This steps is advisable for people who have a fair understanding of running boot disks or who have done OS installations before.if you do not have a fair knowledge and only a general understanding then you can skip this step. Details here

3) Install Ubuntu.

There are many ways to install ubuntu.

  • you can use a Live cd . Request a CD here — ( If you can wait upto 3-7 days)
  • You can download a ISO and burn it on a cd. ( You had rather get ISO for future use and distro)
  • You can also use Wubi . ( You want the easiest and fastest way out)

Once you have the Cd follow the steps below.

  1. Defragment your hard drive in windows first. (My Computer, Right click on drive, Properties, Tools, Defragment Now)
  2. Insert Cd into the drive and reboot. When the PC reboots press F8 or F10 depending on the make of you computer and boot via CD. this can also be done by changing BIOS (On restart – DEL button or F12) settings.
  3. Once you boot through the CD it will load the kernel and you will have a few options or either just test driving ubuntu or installing it completely.
  4. You will be taken through a series of settings like layout,place and a few others till you get to the partition hard drive prompts.

4) Partition using UBUNTU CD

It is better to read some guides on how to have your linux partitions.How much space to leave for you swap and other general information.

If you have come so far then you are nearly there. Now all you need to do is partition your hard drive and restart.

Auto partition.

  1. Choose the very First Option ("Resize IDEmaster, partition #1 (hda1) and use freed space").
  2. Specify the size of the new partition .
  3. Click on "Forward".
  4. If it continues then you can simply finish the installation.You can also choose to do manual partition if you know exactly how you want to split the whole disk.

manual partition

You can use this option if you have a clear idea of what has to be done.

  1. Choose "Manually edit partition table"
  2. Select the partition you want to resize and press Enter.
  3. Select "Size:" –>
  4. Select Yes –>
  5. Type in a new size for your partition, it’s recommended you free up AT LEAST 10 GB of free space for your Ubuntu install. –>
  6. Create a swap partition of at least double your amount of RAM . ( This info is available from windows -My computer-properties)
  7. Create a partition for your Ubuntu installation, at least 10 GB.
  8. Select "Finish partitioning and write changes to disk".

Once you have done this just finish the installation and reboot.It will ask you to remove the cd and once you do that there will be two options the next time you boot your computer.ubuntu would detect your windows installation as well and will be added to your choice of OS.

This should do it.Once you boot into the Ubuntu there are many other things that need to be done.Just like the way when you first installed windows you started installing a lot of programs so you can do the same with ubuntu.

Make sure you update via package manager and keep your system up to date.You can also use synaptic manager to install new programs you like.

Any questions just comment or ask !

Google Gadgets For Linux

Sep 7

Gepostet von admin in Google, Linux | Keine Kommentare

Google Gadgets for Linux provides a platform for running desktop gadgets under Linux, catering to the unique needs of Linux users. We are compatible with the gadgets written for Google Desktop for Windows as well as the Universal Gadgets on iGoogle. Following Linux norms, this project is open-sourced under the Apache License.

An important area where Google Desktop for Linux is different from its siblings on other operating systems is support for gadgets. Now, the Linux version of Google Gadgets will extend the gadgets platform to Linux users. By enabling cross-platform gadgets, a large library of existing gadgets are immediately available to Linux users. In addition, gadget developers will benefit from a much larger potential user base without having to learn a new API.

There’s two main components to the application: one is a common gadget library responsible for running and presenting a gadget, and the other is a host program that allows the user to choose gadgets and run them on the desktop. Currently we have hosts written for GTK+ and QT, with the GTK+ host offering a sidebar similar to that of Google Desktop for Windows.

Accessing Linux Files from Windows – Using Ext FS for windows.

Sep 7

Gepostet von admin in Linux | Keine Kommentare

If you have a desktop with Windows and Linux as dual boot environment and you want to access a few files saved in Linux / Ubuntu file system from the Windows login. For example, you may need to share files such as Docs, PDF, audio, video, etc. from both Linux and Windows. The Ext2 Installable File System for Windows helps you to access Linux drive from Windows.

It provides Windows NT4.0/2000/XP/2003/Vista with full access to Linux Ext2 volumes (read access and write access). This may be useful if you have installed both Windows and Linux as a dual boot environment on your computer.

The “Ext2 Installable File System for Windows” software is freeware.

For the technically minded

“It installs a pure kernel mode file system driver Ext2fs.sys, which actually extends the Windows NT/2000/XP/2003/Vista operating system to include the Ext2 file system. Since it is executed on the same software layer at the Windows NT operating system core like all of the native file system drivers of Windows (for instance NTFS, FASTFAT, or CDFS for Joliet/ISO CD-ROMs), all applications can access directly to Ext2 volumes. Ext2 volumes get drive letters (for instance O:). Files, and directories of an Ext2 volume appear in file dialogs of all applications. There is no need to copy files from or to Ext2 volumes in order to work with them.”
