Deja Vu

If you are reading this, there is a pretty good chance that you are either using ST (Sublime Text) or are about to start using it. Whatever the case, I can assure you that its effing awesome !

So the first three shortcuts that anyone starting out with it should start using are :

Ctrl + G - Goto line number

Ctrl + P - Open file by name (uses fuzzy search)

pprint is a very handy module for printing out objects in a humane form.

Unfortunately it doesnt prettyprint OrderedDict objects properly.

The following is a workaround for printing a OrderedDict object in a manner close to what pprint does for a regular dict

Use json module's dumps method to print the OrderedDict

To stop tracking a file that was previously being tracked by git, do the following:

Sublime Text is an amazing text editor. To make it even more awesome, it has extensive support for all actions using keyboard only. This is the first post in my Keyboard Fu Series wherein I shall post random tips and tricks and shortcuts for using keyboard to do all sorts of action in Sublime Text.

So here is the first one.

To shift focus to the sidebar, use the keyboard shortcut Ctrl+0

To enable autologin in Xubuntu

Open the file /etc/lightdm/lightdm.conf

Note:

Make sure the user is created before modifying the file.

There are many instances when you wish that the current command being exexuted in the terminal goes to the background or that you get a second terminal to execute another command. This use case is pretty common when accessing server without a Graphical User Interface (GUI).

An extremely useful and powerful tool called Byobyu is the answer to this problem. In layman terms you can say that it is a "multi-window" terminal. While that definition is wrong on so many counts, it somehow would help the layman understand byobu.

To install byobu on debian based distributions (Ubuntu / Linux Mint etc.) use the following command:

sudo apt-get install byobu

Following are some of the useful commands for byobu
