Check These Out
swap out "80" for your port of interest. Can use port number or named ports e.g. "http"
$ wget -qO - "http://www.google.com/dictionary/json?callback=dict_api.callbacks.id100&q=steering+wheel&sl=en&tl=en&restrict=pr,de&client=te"
this does the actual google dictionary query, returns a JSON string encapsulated in some fancy tag
$ sed 's/dict_api\.callbacks.id100.//'
here we remove the tag beginning
$ sed 's/,200,null)//'
and here the tag end
There are also some special characters which could cause problems with some JSON parsers, so if you get some errors, this is probably the case (sed is your friend).
I laso like to trim the "webDefinitions" part, because it (sometimes) contains misleading information.
$ sed 's/\,\"webDefinitions.*//'
(but remember to append a "}" at the end, because the JSON string will be invalid)
The output also contains links to mp3 files with pronounciation.
As of now, this is only usable in the English language. If you choose other than English, you will only get webDefinitions (which are crap).
Extract a color palette from a image useful for designers.
Example usage:
$extract-palette myawesomeimage.jpg 4
Where the first argument is the image you want to extract a palette from. The second argument is the number of colors you want.
It may be the case where you want to change the search space. In that case, change the -resize argument to a bigger or smaller result. See the ImageMagick documentation for the -resize argument.

Need package: gksu
Note:
Launching gui app in background that needs sudo, won't work great with our old
friendly style of launching:
$ sudo gedit /etc/passwd &
because this would put sudo in background !
Using gksudo as demonstrated, would popup a gui sudo window.
May be this is a common knowledge, but not knowing this
frustrated me during my newbie year.
