I remembered I had some backlog on older cool stuff from between January and…. some time later, so here, have a few cool links.
The best of 2019 wildlife photography awards – in pictures [photos] – the time for pretty wildlife pictures is now.
Eric Wastl – Advent of Code: Behind The Scenes – Leetspeak 2019 [long video] – Eric Wastl, who runs Advent of Code, talks about the experience, the puzzle writing, and why he does all that.
How to exit vim [mostly text] – literally what the title says, in a very… technically correct way.
Unit Conversion & Significant Figures: Crash Course Chemistry #2 [medium-length video] – Hank Green is a cool guy, Crash Course is great, and I really liked that video because it explains things I remember grumbling about during my studies in a very clear way.
An 18-carat gold nugget made of plastic [mostly text] – people playing with materials and doing fun stuff, like making 18-carat gold that’s far less dense than traditional mixture with silver.
This Astrophotographer Makes the World Turn and the Sky Stand Still [images, some text]- some fun animation of a long timelapse where the stars are stabilized but in the image (but the foreground… not). Pretty trippy.
The donut packing problem [text with images] – someone did math about donut shapes and their ability to fit into boxes.
Turing Trains – computational train track layouts – because making Turing machines out of model train tracks is one of the nerdiest things I can think of.
Background Matting: The World is Your Green Screen – video of a person + picture of the background = green screen. That’s quite cool – and they seem to have beautiful results.
The Computer Scientist Who Can’t Stop Telling Stories – a Q&A with Donald Knuth. Funnily enough, I reached to TAoCP book 2 this week-end 😉
