  • Security researcher Troy Hunt developed a tool to troll spammers wherein the spammers are invited to sign up to a website. The website’s rules for an acceptable password start out easy (must contain a digit), but end up ridiculous (must contain the name of a chess piece). The idea is that spammers spend time trying to create an acceptable password rather than spamming other people. He writes a fun blog post about it. The API is deployed on edge nodes in a simple JavaScript script, demonstrating that not only can edge nodes cache images and static sites, but they can cache the backend code for simple APIs too.

  • In Java, a byte array is mutable. This can lead to surprising behaviour. Here’s an engineer advocating for an immutable byte array to be added to the language.


  • NASA says that its DART spacecraft has successfully altered the orbit of the 160 metre asteroid Dimorphos by around 32 minutes in a demonstration of asteroid impact avoidance.


  • Deepmind announces AlphaTensor, a deep learning system which found new efficient ways to multiply matrices with as few calculations as possible.


  • Slack is an acronym, standing for Searchable Log of All Conversation and Knowledge. It was developed for internal use by a video game company, but became the company’s main product after their games were unsuccessful.

  • Noah A. Haber wins a prize for his critique of Givewell’s strategy to prioritise charitable causes. He says they don’t model uncertainty, which produces a bias in favour of causes with a more uncertain impact.


  • The TV show House is heavily inspired by Sherlock Holmes. Thematically, the parallel is clear: the protagonist uses inductive reasoning to solve cases, rejects cases he finds uninteresting and has a drug addiction. There are also numerous references, the main one being the surnames of Gregory House and James Wilson (compare Holmes and Watson).
