Oh cool, thanks for letting me know! Yeah I vibe coded all the Mac / Swift stuff and have no idea what's going on in there. I considered rewriting in Rust so I can implement other features (streaming; turning the music down when I'm speaking), but good to know clj is an option too.

GitHub - lynaghk/whispertron Contribute to lynaghk/whispertron development by creating an account on GitHub.

My free, minimalist Mac speech-to-text app now transcribes even faster.

Ever since I started talking to my computer, my typing (~130 WPM) feels slow.

Talking also feels more relaxed and exploratory, which is useful when designing new stuff.

A technical drawing of an AirTag with many, many callouts describing the curvature of an AirTag.

Find someone who cares about you as much as Apple cares that AirTag holders fit perfectly.

Here it is — very happy to officially release the book that @marianoguerra.org and I have been working on for the past 2½ years.

If you bought it in early access, thanks for your support! 🙏

If you haven't bought it yet, please check it out!!

The Stingray system The Stingray system combines salmon lice treatment, lice counting, and monitors biomass and fish health in one fully automated system.

> The laser unit is autonomous and will continue shooting salmon lice as long as it receives electricity, even if Internet access is broken.

Reading about superellipses and ran into an offhand reference to "squigonometry". I assumed it was a joke, then I found the Wikipedia page and a Springer textbook. I still can't tell.

Me: I wonder how DIY keyboards are going since I goofed with them during the pandemic? (kevinlynagh.com/keyboards/)

Them: We compiled a BRep CAD kernel to WASM so you can generate complex keyboard geometry in your browser. Also you can scan your hands using computer vision. (ryanis.cool/cosmos/)

Reversibly Sticking Metals and Graphite to Hydrogels and Tissues We have discovered that hard, electrical conductors (e.g., metals or graphite) can be adhered to soft, aqueous materials (e.g., hydrogels, fruit, or animal tissue) without the use of an adhesive. The adhesion is induced by a low DC electric field. As an example, when 5 V DC is applied to graphite slabs spanning a tall cylindrical gel of acrylamide (AAm), a strong adhesion develops between the anode (+) and the gel in about 3 min. This adhesion endures after the field is removed, and we term it as hard–soft electroadhesion or EA[HS]. Depending on the material, adhesion occurs at the anode (+), cathode (−), or both electrodes. In many cases, EA[HS] can be reversed by reapplying the field with reversed polarity. Adhesion via EA[HS] to AAm gels follows the electrochemical series: e.g., it occurs with copper, lead, and tin but not nickel, iron, or zinc. We show that EA[HS] arises via electrochemical reactions that generate chemical bonds between the electrode and the polymers in the gel. EA[HS] can create new hybrid materials, thus enabling applications in robotics, energy storage, and biomedical implants. Interestingly, EA[HS] can even be achieved underwater, where typical adhesives cannot be used.
