Hello World in as many languages as possible.
The primary goal is to create a full functional Hello World program in many languages. Functional means the build scripts, code, config, and tests to allow others to reproduce the behavior. The secondary goal is to create documentation for all languages and tools used.
A minimal bio of contributors.
First real programming was using Fortran in 1984.
Started using C in 1987. First book was K&R and I still quite clearly remember the expression: x & (x-1). So simple yet magical!
Wrote nmake in 1988. Worked on the C++ Compiler till 1999.
Professionally used C, C++, VB, Pascal, Java, JavaScript, perl, C#, Scala, node.js and a few others.
