Here I am posting my multi platform multi call stub.

This is useful if you want to cross compile small tools from same code but also want to make sure that certain functions will work reliably across all platforms. This uses the multicall concept. Once crosscompiled rename binary with target prefix and the right code will run on the right platform.

Editing spreadsheets, making chartwork, talking to people and going in rounds is exactly the opposite of being what a hacker would do. Living in a counter culture and able to make up the world with symbols written on the lattice gives a zen like fulfillment…  (Not in a creative mood, but the following links do partially tell my feelings:)
