interp is a powerful programming language, a testing platform, and a development framework. It is targeted for Linux/Unix-based systems, yet remains adaptable to less powerful embedded systems that were never intended to host an interactive programming language, because all you need is a serial port. I2 is a compiler for interp.
OpenICT HF Teletype Firmware is the software that drives the digital shortwave radio teletype device developed by the OpenICT Foundation. This software can encode and decode messages in the Hellschreiber format, allowing for ease of use and minimum complexity of the radio hardware.
checkcopy is a GUI tool to copy the files and directories to some destination while creating checksums and/or verifying them. It reads all the checksum files, then reads in each file to copy it to the destination. If a checksum is present for the file, it will be verified, otherwise the checksum is written out to disk.
