How to configure Eclipse Mylyn with Google Code project

First you need to install/upgrade the latest Mylyn snapshot version which is 3.11 from this update site
http://download.eclipse.org/mylyn/releases/latest

Then you need to install the Mylyn Web Template connector from the Mylyn Incubator which is at
http://download.eclipse.org/mylyn/incubator/3.11

After following the above steps you will have a Mylyn installation with Web Template connector in your Eclipse IDE.

The next part is configuring the web template connector to read issues from google code issues. There are lot of articles and posts on how to do this. But the following article was the one which worked for me with the above Mylyn version.

After configuring it you will be able to read the Google Code issues from Mylyn Task list :)

Enabling Bluetooth file receiving on Gnome 3.8

Well this applies to Fedora 19. With the default installation you will not be able to receive file from your Bluetooth device such as your smart phone. First of all you need to install the following libraries using your package manager.

gnome-user-share obexfs

Once the above libraries are installed, go into Settings -> Share and enable Bluetooth sharing and make sure you "Save Received Files to Download Folder". After this restart your PC.

Now you can pair your phone with the PC and send files to your PC.

Git branch in bash prompt in bold

If you are using git in your linux box, i'm sure that you wanted the current branch your working to be displayed some where in the bash shell so that you don't need to do a git branch. Well i learnt recently its possible to show the current working branch in your bash prompt. And i wanted it to be highlited in bold which was not the way it was by default. After doing some reading how to customize the bash prompt i was able to get it done.

First you need to have the bash auto completion package installed.

Then you need to add the following line to you .bachrc file to import the git prompt function.

source /usr/share/git-core/contrib/completion/git-prompt.sh

Then you need to customize the default prompt by adding the following line

export PS1='[\u@\h \W\[\e[1m\]$(declare -F __git_ps1 &>/dev/null && __git_ps1 " (%s)")\[\e[0m\]]\$ '

Now open a new terminal and navigate to a git repo. Your prompt will look like below.

How to disable screen blanking on gnome-shell

When watching movies on gnome shell with VLC, the screen blanks out time to time. First it was from the timeout defined in brightness setting panel. But when i disable the screen off setting some how it started to happen with a 10 min timeout again. So when i googled i found out about the below shell extension.
https://extensions.gnome.org/extension/241/yet-another-inhibit-suspend-extension-user-menu/

But this didn't solved the problem as well. But this extension will stop gnome shell from being idle, which will avoid locking your screen. So now it was time to dig more into this problem. After going through various forums i found out that the xserver has a power management mode and a screensaver which will actually turn off the display to save power. And for my surprise this had a default timeout of 10 mints :).

So i did a small modification to the above extension (which i will submit as a patch to the original developer later after some testing), which will execute the javascript statement on disabling screen locking :

Util.spawn(['xset', 's', 'off']);

And on enabling screen locking :

Util.spawn(['xset', 's', 'on']);

What the above "xset s" does is enabling and disabling the screensaver of xserver.

So at least now i have a solution for VLC when watching movies. Hope that this support will added into VLC core soon so that we don't need to have a extra extension installed.

Gnome shell popup menu problem [Solved]

Well if you are a gnome shell user and using eclipse for development you may have come across this bug https://bugs.eclipse.org/bugs/show_bug.cgi?id=343278. Well some thinks its related to java and some thinks its related to SWT. But my friends its a gnome shell bug or i would say a feature that's not yet implemented :).

My Story:
I was sick of unity because of the slowness and high memory usage which is believe its really unnecessary. Yes Yes i know the memory are cheap these days, but still i don't like to wast my memory unnecessarily.

So i went on searching for a DE that fits my needs, i tried gnome shell but gave up because of this problem.
Then KDE ................ Hmmmmm nop not my choice feels bit odd, may be due to the fact that i was a gnome user for very long time now.
Then i tried Cinnamon, well it was not the one i was looking for either. But for for my surprise it didn't had the right click problem. I knew that cinnamon was a fork of gnome shell and if cinnamon can fix this why not gnome :).

Well i did some search on the cinnamon issue list and came across the following issue https://github.com/linuxmint/Cinnamon/issues/482

Great now its time to find the change that they have done. So i went through the cinnamon commit history to find the changes and end up with the following commits.

https://github.com/linuxmint/Cinnamon/commit/f8c7922777b102dc574bb3695fc649b89879ebab

https://github.com/linuxmint/muffin/commit/9e45c4c8f1cc2f92f266a5f8e1c4e83d4ce70ef1

https://github.com/linuxmint/muffin/commit/0e575275078d4b8b518978448bba60f404b3746d

Now you need to clone mutter and gnome shell code from the gnome git repository. Then you need to create new branches based on the 3.6.1 tag for both the projects.

When appling changes you will need to map some files from cinnamon to gnome shell, muffin to mutter as follows since there are some file name differences.

Cinnamon     : src/cinnamon-global.c
Gnome Shell : src/shell-global.c

Muffin     : src/meta/compositor-muffin.h

Mutter    : src/meta/compositor-mutter.h


Now compile and install the changes. The problem will be solved :). I wonder why gnome shell developers are not considering taking this fix in from cinnamon :(.

Make firefox blends into gnome 3 shell

Recently i decided to move the gnome shell due the unity being more memory hungry (still not greedy as windows) and slow. Gnome shell was fast for me and responsive that unity. So when i moved to Ubuntu Gnome Remix the default browser was Epiphany. I love the look and feel of it and the maximize mode which removes the titlebars to get more space. But still i miss firefox due to the add-ons I'm used to. So here comes the search for firefox add-on to make it look like Epiphany. i found the following add-ons which did the trick.

https://addons.mozilla.org/en-US/firefox/addon/adwaita/?src=userprofile
Above Gnome 3 add-on will make your firefox looks more like a gnome 3 application with Adwaita theme.

https://addons.mozilla.org/en-US/firefox/addon/htitle/?src=userprofile
Above will hide titlebars when you maximize firefox.

Thanks for generous people who contribute on making those two plugins.

Changing font size of view titles in Juno

If you are running the new eclipse platform which is 4.2 on linux you have already seen that the fonts sizes of view titles are pretty big. To adjust the font size for your prefference you need to edit the following file e4_default_gtk.css which is inside org.eclipse.platform_4.2.1.v201209141800/css. The version number might differ based on the updates you have installed in your sdk. The following entry in the above file needs to be change by providing the font size you would like to have

In above as you can see i have changed the default size to 8. Now save the file and start eclipse. You will have nice view titles which will match to you preference :).
