AVIF has landed. AVIF support landed in Chrome 85 a few weeks ago. It’s a new lossy royalty-free image format derived from AV1 video and it’s really impressive—it can achieve similar results to JPEG using a quarter of the file size! Jake digs into AVIF in detail, providing lots of illustrative examples created using the Squoosh online compressor, which now supports AVIF encoding. Jake used the same WebAssembly encoder from Squoosh to decode AVIF images in a web worker so that the demos in his article would work even for browsers that don’t yet support AVIF natively.

15 rules for blogging, and my current streak (via) Matt Webb is on a 24 week streak of blogging multiple posts a week and shares his rules on how he’s doing this. These are really good rules.

“I Have Blood on My Hands”: A Whistleblower Says Facebook Ignored Global Political Manipulation (via) Sophie Zhang worked as the data scientist for the Facebook Site Integrity fake engagement team. She gave up her severance package in order to speak out internally about what she saw there, and someone leaked her memo to BuzzFeed News. It’s a hell of a story: she saw bots and coordinated manual accounts used to influence politics in countries all around the world, and found herself constantly making moderation decisions that had lasting political impact. “With no oversight whatsoever, I was left in a situation where I was trusted with immense influence in my spare time". This sounds like a nightmare—imagine taking on responsibility for protecting democracy in so many different places.
A manager on Strategic Response mused to myself that most of the world outside the West was effectively the Wild West with myself as the part-time dictator – he meant the statement as a compliment, but it illustrated the immense pressures upon me.

Array programming with NumPy—the NumPy paper (via) The NumPy paper is out, published in Nature. I found this enlightening: for an academic paper it’s very understandable, and it filled in quite a few gaps in my mental model of what NumPy is and which problems it addresses, as well as its relationship to the many other tools in the scientific Python stack.
