Note: I am using this and definately this is a big improvement over the previous versions. Here is the blog from gnome blog:

After more than a year of heavy development, <a class="zem_slink freebase/en/networkmanager" title="NetworkManager" rel="homepage" href="http://www.gnome.org/projects/NetworkManager">NetworkManager 0.8 was unleashed on the world a few weeks ago.  While we obviously couldn’t make everyone happy just yet, this release includes a ton of great stuff.  Much of it is under the hood, so while it won’t dazzle you in a blinding flash of light, it should still make your head explode.

Linux is just too open

The Problem with Linux is that it is forthright, open and honest. Now I know how much the editors here hate when I anthropomorphize an operating system, but it is fundamentally true.

Linux, in my view, remains almost too honest and too open.

Check file usage using fuser

There is a package called psmisc that provides a useful application fuser. The package provides the below (on fedora):

/sbin/fuser
/usr/bin/killall
/usr/bin/peekfd
/usr/bin/pstree
/usr/bin/pstree.x11

There are couple of options you can provide on the terminal to fuser. The main purpose of the binary is to check the process id of the process using the file. This can be useful if some file operation on a file is blocking something for you 🙂

Linux:Please Don\’t Show the Command Line to the Uninitiated (via postie)

Not long ago I had the opportunity to show off GNU/Linux to a friend. She&#8217;s been a lifelong Windows users and is just your average, non-technical computer user. She&#8217;d heard of this thing called “Linux,” but had never seen a Linux distro in use. So, I gladly booted up my laptop and also the desktop (we were at my house, my wife and I having one of our many cookouts) and showed her Linux Mint 7 via a live CD and also Ubuntu 8.10, which is installed on my family&#8217;s desktop.

Oracle GUI client on Linux with mysql support

I was looking for some nice client for Oracle and mysql. I did find mysql-administrator and navicat to be useful but this is much better. <a href="http://sourceforge.net/projects/tora/" target="_blank">Tora is the client that I am talking about. Installation did not take much time for me..

downloaded the instant client from oracle.com and then the tora rpm from sourceforge.net. Also downloaded the tora-mysql from http://rpm.pbone.net/index.php3/stat/21/year/2002/month/01/day/28

Then tried to install all the rpms found the rpms that were missing and installed them using yum. Once this is done install the downloaded rpms with &#8221;–nodeps&#8221; option of rpm.Put the entries in bashrc
