Various tips
############
Read vk.com without javascript on Firefox
-----------------------------------------
When javascript is disabled, vk.com automagcally redirects you to a page saying
"Your browser is out of date" instead of rendering the actual content, which it
able to do even without javascript.
To prevent the redirect, go to ``about:config`` and set the
``accessibility.blockautorefresh`` setting to ``true``.

Attach to tmux session without changing DISPLAY env var
---------------------------------------------------------
Sometimes I ssh into my PC from another one and attach to running tmux session,
do the work, disconnect and forget about it. Tut then after a while I notice
that I can't start graphical programs from the terminal, or to be precise, from
the shell sessions running in the tmux panes that have been created after I did
attach to tmux from under the SSH session.
I found the solution in the man page of ``tmux(1)``::
If -E is used, the update-environment option will not be applied.
So just use this command to attach and the ``DISPLAY`` environment variable will
be untouched in tmux session::
tmux a -E
