4tH is a Forth compiler with a little difference. Instead of the standard Forth engine it features a conventional compiler. 4tH is a very small compiler that can create bytecode, C-embeddable bytecode, standalone executables, but also works fine as a scripting language. It supports about 95% of the ANS Forth CORE wordset and features conditional compilation, pipes, files, assertions, forward declarations, enumerations, structures, suspended execution, recursion, include files, etc. It comes with an RPN calculator, line editor, preprocessor, compiler, decompiler, C-source generator, a virtual machine, and a multitasking environment.
soft66 is a library and related command line tools for controlling the Soft66AD series of SDR receivers from Kazunori Miura JA7TDO. This enables users of these software-defined radio receivers to tune and use them under Linux. There is also a patch to enable support for this in Linrad.
