Peter "Bobricius" Misenko has released what he claims could be the "ultimate useless gadget" — a self-charging LED necklace.

Posted preprint on acoustics of coral reefs!We deployed underwater acoustic recorders at 10 Singapore reef sites over 2 years.To mitigate ship noise masking low-frequencies,we trained a CNN denoiser.Denoised acoustic data correlated well with diver-based reef health (live coral richness/cover, etc)
Underwater acoustic recorders deployed at coral reef sites, plus a CNN denoiser, reveal distinct morning and evening choruses; denoised data correlates with reef health assessments.

Obsidian on mobile is getting so fast and smooth.
Obsidian 1.11.0 (early access) introduces widgets and a new mobile design.

You can now instantly access Obsidian from your lock screen, home screen, control center, Shortcuts, and Siri.

The new design gives more space to your notes, and helps you quickly navigate your vault.

hot take: every async fn in Rust should have a `# Cancellation` doc comment, saying exactly what it CAN and CAN'T do when cancelled early, and clippy should have a lint for that like it does for `unsafe` functions that are missing `# Safety` section.

New post: a defense of lock poisoning in Rust.

Followup to recent discussion: decided to write about lock poisoning, looking at the arguments on each side, and informed by our experience at @oxide.computer dealing with the parallel problem of unexpected async cancellations

Please give it a read!
In defense of lock poisoning in Rust · sunshowers
It's worth retaining one of multithreaded Rust's most valuable features.

My baby #JuliaLang package got an award!
DifferentiationInterface.jl just received a national prize for open-source research software and I couldn't be prouder. We started this from a vague dream with @adrianhill.de, and reached 1000 dependents and 100k downloads last month.
Research != just papers.

Modern LLMs (GPT-5.1, Claude 4.5, Gemini 3) produce excellent code and can be a significant productivity boost to software engineers who take the time to learn how to effectively apply them - especially if used with coding agent tools

People always want to use ADCs for things you don't need ADCs for. Instead you can just use time constants. The CH572 has no ADCs but that doesn't stop me from measuring battery voltage and the pressure on some silicone buttons.

"octa-SPI", "hexa(-deca)-SPI"

BRO. Those are parallel ports. You have a high speed clocked parallel port. It's not serial if you have 16 lanes.
