Let’s say we’ve got a bunch of functions accessed through a dictionary, like this: def f0(): return 0 def f1(a0): return 0 def f2(a0, a1): return 0 funcs = { 'f0': f0, 'f1': f1, 'f2': f2 } We call these functions like this: funcs['f0']() Now assume we want to call these functions with user-provided arguments. Say, for example, that the user wants to call f1 with argument a. They pass the string 'f1 a'. (read more)

If there was an easy bridge between a Sandstorm instance and Android, I think I’d have an ideal personal server. (read more)
