If you like reading your feeds on Google Reader however dont use the social features (eg sharing items and following other people), there is a way to turn off this feature.

1) Go to Google Reader.

2) Type this in the address bar and let the page reload:

javascript:antisocial('true')

3) The reader will now remove the “People you follow” section and any shared items from your friends.

4) This setting is saved on your Reader account, so to enable it back, just undo it:

javascript:antisocial('false')

There is a nice little trick (or hidden feature) on Google Image Search that allows you to search images of specific resolution size and filetype.  Using this technique, we can search for the right image our desktop wallpaper.  This can be achieved by using the imagesize and filetype search parameter.

For example:

[imagesize:1900x1200 filetype:jpg design] finds 1900px by 1200px images related to design.

[imagesize:256x256 filetype:png icon] finds 256px by 256px icons.
