1KB JS Numbers Station

1KB JS Numbers Station

Terence Eden built a neat and weird 1023 byte JavaScript demo that simulates a numbers station using the browser SpeechSynthesisUtterance, which I hadn't realized is supported by every modern browser now.

This inspired me to vibe code up this playground interface for that API using Claude:

Quoting Dave White

like, one day you discover you can talk to dogs. it's fun and interesting so you do it more, learning the intricacies of their language and their deepest customs. you learn other people are surprised by what you can do. you have never quite fit in, but you learn people appreciate your ability and want you around to help them. the dogs appreciate you too, the only biped who really gets it. you assemble for yourself a kind of belonging. then one day you wake up and the universal dog translator is for sale at walmart for $4.99

I Watched It Happen in Hungary. Now It’s Happening Here. “I came to understand that the real danger of a strongman isn’t his tactics; it’s how others, especially those with power, justify their acquiescence.”

Quoting ICML 2025

Submitting a paper with a "hidden" prompt is scientific misconduct if that prompt is intended to obtain a favorable review from an LLM. The inclusion of such a prompt is an attempt to subvert the peer-review process. Although ICML 2025 reviewers are forbidden from using LLMs to produce their reviews of paper submissions, this fact does not excuse the attempted subversion. (For an analogous example, consider that an author who tries to bribe a reviewer for a favorable review is engaging in misconduct even though the reviewer is not supposed to accept bribes.) Note that this use of hidden prompts is distinct from those intended to detect if LLMs are being used by reviewers; the latter is an acceptable use of hidden prompts.

A Behind the Scenes Look at NPR’s Tiny Desk Concerts

Follow Architectural Digest as they head behind the scenes at the offices of NPR Music to see how the now-iconic Tiny Desk Concerts come together. My favorite bits are the callouts of all the stuff on the shelves behind the artists: Adele’s water bottle, Sabrina Carpenter’s bedazzled martini glass, a Green Bay Packers helmet signed by Harry Styles. And: “Chappell Roan’s wig is actually sitting on Cypress Hill’s skull.”
