V1 is a simple functional interpreter language with syntax from C, PHP and JavaScript. It was developed from the scratch. The focus is on simple administrative and experimental programming, but it has enhanced benefits like Multithreading, CGI, Web functions and Native function calling. The most buildin functions are compatible with PHP, for example fopen(). The current Version 0.96 is available for Windows (32 Bit, WinXP, Win7, Win10+), Linux (x86, 64 Bit, libc 2.2) and Linux (ARM, 32 Bit, libc 2.28). Tested ARM systems: Raspberry Pi Zero, Banana Pi Zero.

VDMPad is a simple Web IDE server for VDM-SL based upon VDMJ and Squeak Smalltalk. You can launch a VDMPad Server on your Mac or Linux PC and open "http://localhost:8085" with your browser. Although VDM does NOT run on Windows platforms, you can use Windows/iOS/Android devices to open VDMPad running on Mac or Linux server.

Waxeye is a parser generator based on parsing expression grammars (PEGs). It supports C, Java, Javascript, Python, Ruby and Scheme.

As you may recall, a Turing-machine is an all-purpose computer. A Turing-machine has a memory that consists of a track or line of data. On the track, a read-/write-head is moving. The read-write head itself is a state engine, which is affected by the input from the track, and which decides what to write on the track, and where to read the next input, by "moving" the head back or forth. In 5050, the part of the track left of the head is represented not by a line or stack of information, but by a binary tree. The part right of the head is represented by a binary tree, too. The head itself sort of sits between the two trees, but will often change its state according to information from the right side of the left side. In 5050, the state of the head itself is again represented as a tree of commands, although for simple programs, a linear representation can be sufficient.

nScriptHost is a .NET library that supports VBScript and JScript. It allows developers to integrate scripting into their applications and expose objects from the application to the scripting engine so that scripts can interact with the application.
