Hacking

Updated on

In hacking, a computer pretends to be made out of things like ‘buffers’ and ‘lists’ and ‘objects’ with rich meaningful semantics, but really, it’s just made out of bits which mean nothing and only accidentally can be interpreted as things like ‘web browsers’ or ‘passwords’, and if you move some bits around and rewrite these other bits in a particular order and read one string of bits in a different way, now you have bypassed the password.
