""" Module to compute projections on the positive simplex or the L1-ball

A positive simplex is a set X = { \mathbf{x} | \sum_i x_i = s, x_i \geq 0 }

The (unit) L1-ball is the set X = { \mathbf{x} | || x ||_1 \leq 1 }

How to tunnel SSH over SSL/TLS

laptop ssh -> laptop stunnel -> evil network -> internet -> your server -> your server ssh

Server (your shell server/home box/work box/whatever)

Sets up a stunnel process listening externally on port 2443/tcp, forwards to localhost 22/tcp

• Install stunnel, e.g. yum install stunnel
• Install server config snippet to /etc/stunnel/stunnel.conf
