Manufactoria is an online puzzle game, which is deceptively simple and surprisingly deep. Your task is to build a factory machine from simple components which takes an object, inspects it and moves it around the factory floor accordingly. In later stages, you get to modify the object as well.
At first you think you’re just moving objects around and printing patterns of coloured dots on them, but later, when you’re thinking of blue dots as 1s and red dots as 0s, and the patterns as binary numbers, you realise that the system is Turing complete and the game’s progressively harder puzzles are teaching you how to build a binary adding machine. It’s a beautiful, powerful way to demonstrate the principles behind mechanical/electronic computation.
While some games, like Angry Birds and Candy Crush, are meant to numb your brain with repetitive tasks, the best ones expand your brain with new skills and knowledge: Manufactoria is in the latter class.
As soon as the Coalition Government started cutting the flood defence budget in 2010, it was as predictable as the water cycle what would happen next: within no more than a few years and probably within the lifetime of the government which made the cuts, there would be heavy rainfall, resulting in massive floods, and a backtrack on the cuts – emergency spending if not a change to the planned budget – either way, a tacit admission of failure.
This sort of thing seems crashingly inevitable to me. There’s an obvious trajectory, of reduced budgets, reduced regulation or reduced oversight, followed by conspicuous calamity, followed by attempts to mop up the mess which generally involve reimplementing whatever system had originally been in place to prevent the calamity.
I’m not here to congratulate myself on uselessly predicting the flooding crisis (also, because I never went on record predicting it, so there’s no proof I ever did). I want to teach you how to predict similar balls-ups in the future, because the depressing thing is, it’s not that difficult.
The theory of evolution is a theory; evolution is a process, a thing which definitely exists and happens. The fact there’s a theory about it is not to say the whole thing is just a wild idea someone pulled out of their arse; it’s scientists’ way of saying “this stuff’s complicated, so we’re going to write it down properly.”
