tmux cheat sheet

tmux -CC attach iTerm to tmux
tmux new -A -s <session-name> creates a new named session or attaches to that session if already exists
control + b - commands
- “ creates a horizontal pane
- % creates a vertical pane
- q shows pane numbers, if you hit the number on the keyboard you will change to that pane
- o moves between panes
x kills the current pane, exit command also works

Google Chrome: Source maps not updating after live reload.

After a css live reload we noticed that source maps did update and line numbers shown in the style inspector where correct but the source files did not change. A quick close and open of the inspector seems to fix the issue.

Tested on Chrome:

47.0.2526.73 (64-bit): Has the problem
47.0.2526.73 beta (64-bit): Has the problem
49.0.2579.0 canary (64-bit): Works sometimes

Using ember-cli on Beta:

	* Lightweight, dependency-tracking reactive state management system

	*
	* Key components:
	* - Subscribable: Interface for reactive values that can be observed
	* - Signal: Core primitive for wrapping a value in a reactive container
