GNU parallel is a shell tool for executing jobs in parallel locally or using remote computers. A job is typically a single command or a small script that has to be run for each of the lines in the input. The typical input is a list of files, a list of hosts, a list of users, a list of URLs, or a list of tables. If you use xargs today you will find GNU parallel very easy to use, as GNU parallel is written to have the same options as xargs. If you write loops in shell, you will find GNU parallel may be able to replace most of the loops and make them run faster by running several jobs in parallel. GNU parallel makes sure output from the commands is the same output as you would get had you run the commands sequentially. This makes it possible to use output from GNU parallel as input for other programs.
The Barefoot server is a scalable user-space port bouncer that can be used to forward, or bounce, TCP connections and UDP packets destined for an address on the host on which the Barefoot server runs to any other host or address. To these other hosts, it will appear as if the connection and packets are coming from the machine on which the Barefoot server runs, rather than from the original host. The Barefoot server has support for using proxy protocols on the outgoing side, and can relay incoming traffic out via a SOCKS server or an HTTP proxy supporting the CONNECT command. At the moment, using a proxy for outgoing traffic is only supported for the TCP protocol. The Barefoot server is targeted towards larger sites that need to bounce traffic from many simultaneous clients, while at the same time offering detailed access control, logging, and other features related to controlling the behavior of the traffic and the Barefoot server.

"Stupid Simple VPN" is a virtual private networking program contained as source in a 7.0KB tarball. It does not daemonize, and is intended to create a temporary VPN for emergency circumstances when you "just need a pipe" without the hassle of authentication, keys, encryption, and compression. It runs on OS X using the tuntaposx driver and Linux 2.6 using the native tuntap driver.
