Isn't It Time for AVIF Everywhere?
Hosting providers, platforms, and phone makers should adopt AVIF and AV2 more widely, the author argues. Hetzner raised prices multiple times in 2026 citing rising hardware costs, partly driven by AI demand. AVIF generally compresses better than WebP at comparable quality, and the author has switched to AVIF everywhere it's supported, falling back to WebP otherwise. YouTube is preparing to move from AV1 to AV2 as early as 2027. The author also wants better native support for Apple's HEIC format alongside AVIF, and suggests users encode AVIF locally before uploading to ease server load.

Locating the source of a mysterious beep with Claude
Simon Willison used Claude Code to build Beep Locator, a system that triangulates the source of an intermittent beeping sound using multiple devices as listeners. The Python web server coordinates phones, iPads and laptops over WebSockets, using Fast Fourier Transform beep detection and a chirp to align recorded clips, and Willison names the 2007 BeepBeep acoustic ranging paper as the research Claude found. The tool located the beep to within about 40cm, which turned out to be an ancient carbon monoxide detector that wanted its batteries replaced. He started with Claude Code Cloud running Opus 5.5 on his iPhone, then continued on his laptop after Fable 5.2 was released, iterating live by pushing new JavaScript to listening devices so they did not need to be manually restarted.
