I recently got a Venova and have been enjoying learning how to play it: It combines a saxophone mouthpiece with recorder fingering and a little nose to overblow an octave instead of a twelfth. It's somewhere between a real instrument and a toy, and one of its bigger problems is...

This afternoon Cecilia and I played for Somerville Porchfest, with Harris calling and Danner running sound. There was rain, but not enough keep us from playing, or to keep folks from dancing: We were originally planning to be on Morrison Ave, where we've been for years. Two weeks out, though,...

A week ago the Copy Fail vulnerability came out, and Hyunwoo Kim immediately realized that the fixes were insufficient, sharing a patch the same day.

Damon Binder recently wrote up an argument for prioritizing air filtration over far-UVC for pathogen control: > UVC and filtration are close substitutes—both deliver effective air changes per hour, both reduce airborne pathogen concentrations by the same amount per eACH—and on current pricing, filtration is cheaper. There's a lot of...
