a silly script to write in your github timeline

writeInGithub.js

/**
 * so here the thing ... you go in your github page
 * as example I go here: https://github.com/WebReflection
 * you open your console
 * you copy and paste this shit
 * then you write and execute in the console
 * write("Hi There!");
 * NOTE: Pixel Font from a 2006 project of mine :-) http://devpro.it/pixelfont/
