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.
OpenSCB is a hardware and software solution for controlling servos over USB. The hardware is designed to interface with classic RC servos, AX-12/AX-18 servos, OpenServo, and more using a powerful 32-bit microcontroller with a USB port for programming and control with a PC. The schematic and layout will be available and can be customized. A graphical interface is also provided for your computer to configure, calibrate, and control the board.
ERDvideo is an application to display video in an HTML5 capable Web browser. As part of the ERDialog Web Framework, this application is an applet that can be installed and used through a Web browser. This application requires Erlang and Yaws and should run on all platforms. Ogg videos can be viewed without Flash or any other programs.
Shannon is a general purpose stream-oriented programming language; it is concise and yet feature rich. Streams, FIFOs, and Unix shell-style pipes are first-class concepts in the language. You can connect functions and FIFOs within your program similar to the way you connect processes with pipes in the Unix shell. These constructs in Shannon, however, are highly efficient as no true multitasking is involved, and at the same time they allow you to write more concise and readable code for chained data processing. State is a special type of function that returns a reference to its own local data and any nested functions it may have. In effect, states implement classes in terms of OOP, and yet classes per se aren't part of the language. A special type of modules marked as "persistent" is an effective replacement for databases and SQL. This allows you to access persistent shared data using native Shannon constructs, eliminating the need for an extra query language. Intuitive and minimalist syntax and semantics are used. Particularly, "minimalist semantics" means less things to remember and more possibilities. Shannon is statically-typed, although it provides dynamic typing facilities as well.
"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.
