sVimPy is a very small Python virtual machine intended for use in microcontroller projects. At the moment, it supports about 3/4 of all opcodes used in python3k. Most data types are supported. The intended goal is to use this VM in environments like Atmel's ATmega chips (2-8kb RAM). The microcontroller bootloader is still missing (no arduinos left for experimentation). Classes are not supported. Features include: function calling, a stack based VM, garbage collection, very low memory usage, an interactive debugging console, dictionaries and tuples, iterations, VM single stepping (game loop usage is possible), C function calling, a small memory footprint, fast performance, the ability to be used as a library in other projects, a simple API + code, possible usage as a small deployment executable for Python projects.
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.
teeterl is a lean, portable implementation of Erlang. teeterl starts from a single executable file without any additional harness. teeterl is built using Apache Portable Runtime, a library tested on dozens of OSes and their flavors. teeterl borrows from industry-standard Erlang/OTP, especially when it comes to compiler front-end. teeterl provides the concurrency power of Erlang without any telecom cruft.
