If they didn't do that people would probably be commenting that its fake or AI.

A Baofeng UV-5R cannot receive shortwave, it's in the VHF/UHF range for receive/transmit and can receive commercial FM broadcast.

A good analogy for equal temperament might be the Gregorian calendar, as a year does not evenly divide perfectly into 365 days. So in order to compensate for that we adjust the calendar by a leap year every so often to make the calendar more accurate in the longer term. That's kinda similar to how every note is a little off in equal temperament so that at the larger scale of being able to play all intervals works out.

No, they mean we actually clear US customs in Canada as non-US citizens.

Same, I haven't been able to get gemini or claude to tell me to walk a single time and I've even tried changing the distance in the prompt, etc.

It's a within-subject design and they literally did a power analysis in the paper. This is not absurdly low n.

lukeinator42 — Sat, 14 Feb 2026 17:24:19 +0000

I have a couple slings my cousin brought back from Tibet, and a few years ago when I was in Peru I brought some back from there as well (they're called 'huaraca' in Quechua I think). I find it interesting that many cultures used them historically but it never became a sport like archery, javelin, etc., did.

They're very lightweight and are definitely an underrated backpacking tool for keeping marmots at bay when they're attacking your tents and gear, haha.

I was also wondering this, and in one of the footnotes they say "Given that our experiment was conducted in 2025, one might wonder whether Kansas’ updated law is reflected in GPT’s training data and thus skews its decisions. We find no evidence of such contamination." when talking about a specific updated law. But how does one have 'no evidence of such contamination' without seeing the training data?

This is an interesting article from a couple of days ago about tracking diy balloons long distance: https://spectrum.ieee.org/explore-stratosphere-diy-pico-ball.... Given the tracker can be built for $14 it might be worth it to test a version with just the custom hydrogen enclosure and tracker and see how far it gets.

I think it's worth looking at this commentary on the study: https://arxiv.org/pdf/2601.00856. It aligns with a lot of our intuitions, but the study should definitely be taken with a grain of salt.

Light mode constricts your pupil more, which means less eye strain for the eye when focusing because of the better depth of field. Also, black pixels != no light except in technologies such as oled, but most laptops are backlit lcds.

It's only line-of-sight, but isn't the range 10s-100s of kilometres in open areas? Some repeaters on hills/mountains etc. could connect large areas potentially.
