Nifty Things to Do with GIMP

Nifty Things to Do with GIMP Some of us are probably addicted to capturing moments in pictures. I can understand why. It’s one of those things that help us go back to the good old days, so to speak. It’s also something that creates a ‘time machine’ for us because those pictures show us what things looked like, not just remind us of the feeling but give us the atmosphere all over again.

query and downgrade selected packages based on version or repository

If you have worked on rpm based distro then you know how difficult it is to downgrade packages. And unluckily I upgraded some packages to fc12 and was still on FC11. Completely my mistake while doing some R&D. Anyway to downgrade I had to device some mechanism and here it is:

rpm -qa –qf ”%-30{NAME}%-20{RELEASE}\n” |grep fc12 |awk '{print $1}’|tr ’\n’ ’ ’ >downgrade

yum downgrade `cat downgrade`

EncFS – Simple article to use Encrypted filesystem in Linux

A nice article here

EncFS is an easy-to-use, command-line tool for storing information in encrypted form. It’s not really a file-system, but it pretends to be one at the CLI. If you’ve been searching for a means of encrypting and decrypting your sensitive data easily, here it is.
User Level: Intermediate
EncFS is included with the distribution I’m using on the desktop, Ubuntu Dapper, so all I needed to do to install it was a few clicks in Synaptic. Look for the encfs package, and select if for installation. It should pull down all of the dependencies for the system. If you’re not so lucky, and your distro doesn’t include EncFS packages, you can download the latest tarball from a here and build it from the source. See the EncFS site for a dependencies.

Initialization or clearing of log files

Like all Unix file systems, open log files can cause a real problem when they get too large and need to be deleted. The problem is, if you delete an open file, the link is removed, but all of the inodes are lost. Even worse, if the program continues to log to the file, the link never re-appears, and additional inodes are lost and are unrecoverable. I suggest two solutions to the above problems.

Change information for the user on Linux machine.

Today I have couple of hours to spare and thus thought might as well spend it on my blog. The finger command in *nix systems is used to display the information on the users. This information is taken from the /etc/passwd file. You can use the chfn command to change the information.

Fedora people put up a repo for the chrome web browser and it is quite frequently updated. All you need to do to install the browser is following:
