This is the extension of my previous article on facebook share. But, no need of prior knowledge. Proceed from here. After registering a developer account @ https://developers.facebook.com/ , create an app. Note the App-Id and don't forget to add the redirect url under the app settings section. Also add all the access permissions you would like to get from the user under Auth Dalog section. All these permissions are to be used later to retrieve corresponding data. URL pattern to implement the authentication is as follows: http://m.facebook.com/dialog/oauth?client_id=<APP-ID> &redirect_uri=<PATH- TO-TARGETTED-LOCATION> &scope=<ALL-THE-PERMISSIONS-LIKE-email,offline_access> &response_type=token Just modify the CAPITAL lettered data, and for the redirect-url no need of using quotation marks ("")

We can add the tweet button directly from the twitter website. But if you want a image of you wish, then it's easy to get it. <a href="http://m.twitter.com/home?status=WHATEVER-YOU-WOULD-LIKE"> <img src="SOME IMAGE, BUT KEEP IT RELEVANT" /></a> And if you are developing any application and want to implement authentication, use OAuth provided in twitter API: https://dev.twitter.com/docs/auth/oauth Note: You have to register a developer account and create a app there. For authentication use the access token generated on the app settings page.

This is the most simplest way to add a facebook share button. Use the following code as the reference(href) attribute of your anchor tag(<a>) "http://www.facebook.com/sharer.php?u=<text or url to post on wall>" You can use any image to show the share button, but be precise in selecting it, as the user should get on it easily. Consider the following sample code: <a href="http://www.facebook.com/sharer.php?u=https://thechaithanya.wordpress.com"><img src="http://www.acrnet.org/uploadedImages/Get_Involved/facebook-logo.png" alt="share on facebook"></a> If you are developing any applicetion or website and want the post to be displayed as it was posted from your app, like " via theChaithanya ", use the following code:          "http://m.facebook.com/dialog/feed?app_id=YOUR-APP-ID&link=LINK-TO-BE-POSTED&redirect_uri=PATH-TO-LOCATION-AFTER-SHARE" On successful sharing it w

You can easily reset Unity or Compizusing the following commands (be careful when using these commands and only use them if you really have to!): - to reset the Unity launcher icons: unity --reset-icons - to reset Unity: unity --reset - to reset Compiz: gconftool-2 --recursive-unset /apps/compiz-1 unity --reset

The user switcher indicator (or Me-User-Indicator or whatever is called) can be useful if multiple users log in on your computer but if it's just one user, you can get more space by disabling it. Presuming you've already installed the "dconf-tools" package: press ALT + F2 or open a terminal and enter: dconf-editor Then navigate to  apps > indicator-session  and uncheck the box next to "user-show-menu", then restat Unity (ALT + F2 and enter "unity --replace") or log out and log back in.

You no longer need to whitelist Qt applications but you may still need the systray for other applications such as Shutter, Jupiter, etc. You can whitelist the systray using the following command: gsettings set com.canonical.Unity.Panel systray-whitelist "['all']" Then log out and log back in.

If you don't like the overlay scrollbars, you can remove them using the following command: sudo apt-get remove overlay-scrollbar liboverlay-scrollbar3-0.2-0 liboverlay-scrollbar-0.2-0 Then, restart your computer (performing a logout only may not be enough). To revert this change, install the packages back: sudo apt-get install overlay-scrollbar liboverlay-scrollbar3-0.2-0 liboverlay-scrollbar-0.2-0 And restart your computer.

Install Syanptic (Ubuntu has omitted it, but I like it) Synaptic package manager is not installed by default in Ubuntu 11.10 and while Ubuntu Software Center got many new features, it still can't do everything Synaptic can. Install Synaptic back using the following command: sudo apt-get install synaptic

Cairo dock is a Mac OSX dock-like application that you can install in your Linux machine. One of the advantage that it has over other docks is that it does not require any compositing window manager to work. Even on a low-end PC, it will still work fine. This is not possible for docks like Avant Window Navigator which depends on compositing manager (such as Compiz) to function. If you are using a PC that does not support any compositing manager, or you wanted to try out alternative dock for your Ubuntu machine, follow this tutorial to install and configure Cairo Dock on your Ubuntu Intrepid. *It can also be installed directly from the Ubuntu Software Center * Installing Cairo dock Adding the repository In your terminal, gksu gedit /etc/apt/sources.list Add the following line to the end of the file. Save and close. deb http://repository.cairo-dock.org/ubuntu intrepid cairo-dock Add the signed GPG key: wget -q http://repository.cairo-dock.org/ubuntu/cairo-dock.gpg

lxSplit is a simple tool for splitting files and joining the splitted files on unix-like platforms, such as Linux, FreeBSD, OpenBSD, etc. lxSplit splits and merges files with the -s and -j flags respectively. Starting with version 0.2.1, lxSplit can handle large files (>= 4 GB) both when splitting and joining. It can be installed from the ubuntu software centre. Usage: To split a big file into smaller pieces of 15 MB each, run the following command: lxsplit -s hugefile.bin 15M Output size can be given in (M)egabytes, (k)ilobytes and (b)ytes. To merge (join) the already split pieces into the original big file, run this command:  lxsplit -j smallfiles.bin.001 All resulting files (from either splitting or joining) will be placed in the current directory.

Install Compiz Config Settings Manager Compiz desktop effects are available in your Ubuntu by default and if you have any kind of 3D acceleration available(graphics driver ie), you are good to go with Compiz.

Simply copy paste the following command into Terminal to install "compizconfig-settings-manager". sudo apt-get install compizconfig-settings-manager Then change the size and transparency levels as per your wish
