JSON is not a YAML subset (2022)

JSON is not a YAML subset People on the internet believe that JSON is a subset of YAML, and that it's safe to parse JSON using a YAML parser: Following this advice will end badly because JSON is not a subset of YAML. It is easy to construct JSON documents that (1) fail to parse as YAML, or (2) parse to valid but semantically different YAML. The second case is more dangerous because it's difficult to detect. False has over "1.7e3" named fjords YAML (infamously) allows string scalars to be unqu

Does the Bitter Lesson Have Limits?

Recently, “the bitter lesson” is having a moment. Coined in an essay by Rich Sutton, the bitter lesson is that, “general methods that leverage computation are ultimately the most effective, and by a large margin.” Why is the lesson bitter? Sutton writes: The bitter lesson is based on the historical observations that 1) AI researchers have often tried to build knowledge into their agents, 2) this always helps in the short term, and is personally satisfying to the researcher, but 3) in the long r

‘Foundation’ Just Dropped a Huge, Terrifying Twist

Foundation is currently rolling out a third season stuffed full of dramatic resonance. We’ve always been fans of Demerzel, the ancient android played by the excellent Laura Birn, but season three has really elevated the character—even beyond that big season-two reveal that she’s been moving the chess pieces on behalf of the galaxy-ruling Empire for generations. That was a monumental bit of information. But this week’s episode, “The Stress of Her Regard,” dropped a bombshell that’s even more sta

This Detroit startup is turning to utilities to make home efficiency upgrades cheaper

Ask any homeowner: renovation projects are no fun at all. From finding a contractor to determining a fair price, the process is rife with uncertainty. Plenty of startups have popped up to help homeowners tackle electrification projects, including installing solar panels and replacing gas furnaces with heat pumps.

Persona 3 Reload arrives on Switch 2 in October

The Nintendo Switch was a great place to play Persona games, and it looks like the outgoing console has passed on the torch to its successor, with last year's Persona 3 Reload kicking things off when it comes to Switch 2 on October 23. Reload is a full remake of 2006's Persona 3 (later ported to the PSP as Persona 3 Portable), which Engadget's Mat Smith called "a gorgeous version of itself" in his review. It's both one of the most confusing and influential entries in the long-running series, an

150 years of Hans Christian Andersen

There once was an ugly duckling, so despised by the other birds that he fled the farm to explore the wider world. But because of his very great ugliness he was taunted there too, until one day he caught his image reflected in a pond and he had turned into a beautiful swan. The Ugly Duckling, first published in 1843, was one of Hans Christian Andersen’s many autobiographical fairy tales: “It matters nothing if one is born in a duck-yard,” he wrote, “if one has lain in a swan’s egg.” Andersen’s s

The fight for the Iron Throne will continue in season three of House of the Dragon—just don’t ask George R.R. Martin for his thoughts about it—and the HBO series is adding another key cast member to reflect that. So far we’ve learned about new knights joining various sides of the war, including fan-favorite Northman “Roddy the Ruin.” And now we’ve got a new woman entering the male-dominated fray to throw her support behind Rhaenyra Targaryen: Alysanne Blackwood, to be played by Annie Shapero.

Next-Gen Xbox and PlayStation Might Not Bore Us In the Switch 2 Era

Let’s forget about the mudslinging that occurs when anyone brings up the two big console makers who don’t have a big “N” in their name. Instead, let’s ask a simple question: what do we actually want from a next-gen Xbox or PlayStation? The latest rumors suggest 2026 could be a big year for Microsoft and Sony, as both may pump out new consoles with PC-level graphics capabilities and handheld gaming platforms to compete with the Steam Deck and Switch 2. The only caveat that’s going to deflate our
