TypeScript and currying

In functional programming you often want to apply a function partly. A simple example is a function add. It would be nice if we could use add like:

var res2 = add(1, 3); // => 4

var add10To = add(10);
var res = add10To(5); // => 15

Rails startup with bundler, rvm and specific user

e.g. for user stefan, starting two different applications, located under /apps/APPLICATION/prod/current.

This script is very useful, because it is run at startup of server, so no 503 anymore.

Put this script under /etc/init.d/ and make it executable chmod +x /etc/init.d/rails_apps

#
# can now be written like this (note those parentheses required by the operators precedences):
