gigacount is a smartphone app that simulates radiation measurement. The camera takes pictures of objects. It stores the pictures as files or transmits them to a service on the network. A user sees the preview of the camera and a number that represents the (estimated) value of radiation. She can set up the application to display random numbers and which format/unit. It also includes options to alter preview color or display a static meter background.
EARL is an HTTP tunneling proxy. It uses the POST method to transfer data. Since its datagrams are serialized objects, the traffic overhead is rather large. The datagrams are encrypted using AES to provide privacy and obfuscation to proxy maintainers. Inbound and outbound connections are possible. It is recommended to combine it with SOCKS proxies for a comfortable setup.
ajax-cross-browser-using-iframes uses Iframes, an empty div, and innerHTML, allowing you to create AJAX calls. It is a little bit confusing at first, but once you understand it and place the necessary nested PHP files, it will allow you to create unimaginable things. It is cross-browser.
Octave daemon is a network daemon for GNU Octave, implemented in PHP. The package also contains a PHP client for connecting to the daemon. Native PHP applications can also use the connector class to run ad hoc Octave instances, circumventing the daemon altogether (which can be useful for development or small projects).
