This made me laugh out loud. Keep the link for the next time you need an analogy for an app idea.

A Taxonomy of Access Control (Schneier on Security). In an elegant nutshell, this feller has defined the four states that a key or account or whatever can be in as “safe, loss, leak, and theft.” It’s a very elegant and simple set. Linked to Schneier because the source is a paper on cryto wallets, and no-one has time for that shit, and also because the discussion on Schneier’s post is mostly interesting.

I have started listening to John Finnemore’s Souvenir Programme, which is a comedy series from BBC Radio 4 and so far, I like it.
