tmux cheat sheet

(C-x means ctrl+x, M-x means alt+x)

The default prefix is C-b. If you (or your muscle memory) prefer C-a, you need to add this to ~/.tmux.conf:

Test mbostock's awesome bl.ocks.org

Somehow the author keeps on reiterating this point the reason for which essentially boils down as below

The client need not know the internal implementation/representation of the class/object
If exposed, it would become cumbersome in the event of changing the implementation/representation of the class, which may cause several breakages in client code. On the other hand if the field was exposed through getter methods, the change in the implementation would have gone unnoticed by the client.
Allow public access, if neccessary only in case of static final and primitive fields.(even in this case, when the field or object itself is passed from one thread to another, one needs to exercise caution - why?)
But a final array field may not become immutable after all. In that case make it private and expose an unmodifiable public list field. Or make it private and provide a getter method which returns a copy of the array.

As configured in my dotfiles.
