Open sourced my Markov chains toy. I've used it to generate fake Finnish click-bait headlines

Any idea how this kind of a high-resolution bit pattern could be physically printed? (It's a Gray code rotary encoder)

+Oona Räisänen it's hard to tell scale. A laser printer gets up to 1200 dpi, I think. It's a cheap experiment to try to see what you can get away with. Also, I wonder if the optical sensor samples at a single square point or if it samples a rectangular area -- assuming it's optical. It might be picky about having a white background versus a foil background.

Interesting story about a cheating scheme in the Millionaire game, involving secret signals hidden in plain sight. From 2001, but I hadn't heard of this.

I'm going to leave this here, just to convince you that you need a tripod :)

Barcode recovery using a priori constraints
Barcodes can be quite resilient to redaction. Not only is the pattern a strong visual signal, but also the encoded string that often has a rigidly defined structure. Here I present a method for recovering the data from a blurred, pixelated, or even partiall...

As animals grow their winter fur, plants also grow winter leaves.

It has been so warm and wet in Indy that this hasn't happened here. (Yet.) Usually get a deep freeze in January, though.
