Tricks for GPU-composited CSS – Some nifty hacks to keep your browser animations on the fast path.

How to commit fraud and get away with it – An offbeat but compelling argument that data systems in large corporations often exist to allow management to commit fraud with perfect deniability.

Once we have those, all sorts of projects will be verifiable.
