Libbraille makes it easy to access Braille displays and terminals. It can write text on a Braille display, directly draw Braille dots, or get the value of pressed keys. It is compatible with a wide range of Braille displays, and can autodetect some of them. A virtual GTK+ display is provided so that developers can test how their application would be rendered in Braille.
Sval is a Web service which charts the closing price of a stock listed on the American Bourses versus the closing values of the DJIA, NASDAQ, and S&P500 over a given period of time. The chart is returned to the user as a SOAP message attachment in PNG, JPEG, or SVG format. This project is a testbed for investigating a wide variety of Web service technologies by implementing the same Sval Web service using different architectures.
