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.

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.
