There is a calculator called bc that works in the command line. So if you need a quick calculator function in the command line then you could write some functions that will do the trcik for you. Here is an example:

Upgrade to Fedora 13 from your existing version using yum.

2010-04-21 1 min read Fedora Uncategorized

Well. this time it seems to be very simple :

yum –releasever=13 upgrade

update 22/April/2010:
The key file will not be there so there are two options for you in this case:

Install the following rpms from the downloaded rpms with ”yum –nogpg localinstall”
a) fedora-release
b) fedora-release-notes
Run the whole upgrade with –nogpg option.

Issue observed after the upgrade:
The new kernel was not added in the grub menu and I had to manually add the below entry in the <a class="zem_slink freebase/en/gnu_grub" title="GNU GRUB" rel="homepage" href="http://www.gnu.org/software/grub/">menu.lst file:

Liquid rescale and remove objects from the images.

2010-04-12 1 min read Fedora Photo

Ever wanted to remove some unwanted object from an image. Wonder how many thinkgs you have to do, clone and delete and what not:)

There is a simpler way, just paint it in foreground color. Does that sound ridiculous, not any more with Liquid Rescale. First install the plugin for liquid rescale for gimp.

yum install gimp-lqr-plugin

Now, just follow simple instructions below:

in the menu, choose Layer and then Liquid Rescale

click on the New button in the Discard features section on the right: a new layer will be created

put the plugin window on one side of the screen without closing it, and go back to work on the gimp main windows

choose the paint tool and paint over the area you wish to remove

go back to the plugin window

click the Refresh button at the bottom: you should see your discard mask appear in the preview

optionally, in the Mode box on the left choose Lqr + scale back or Lqr + Lqr back

click the Auto size button at the bottom of the Discard features section (optionally choose the scaling direction in the box at the side of the button before clicking it).

click OK

Could it get any simpler.

Linux Advocacy and cool things to do with Linux.

2010-04-12 2 min read Linux

I have heard a lot of Linux advocacy and read probably a couple of artilcles also on them but they lack one thing : the end user perspective. Linux is great no doubt, but there are far too many things to confuse people at all levels. For example, if you do a google search for which distro is good for me, you will find different sites giving you different results. So, whats my point?

recursively add directory and files to cvs from Linux.

Go to the directory which you want to add to cvs and execute the following:

cvs login

find . -type d -exec cvs add {} \;

find . -type f -exec cvs add {} \;

cvs commit

That was simple 🙂
