Why? AI beat rainbolt 1.5 years ago: https://www.npr.org/2023/12/19/1219984002/artificial-intelli...

AI tends to have superhuman pattern matching abilities with enough data

karlding · 4 months ago

If you watch the video, (one of) the reasons why the AI was winning was because it was using “meta” information from the Street View camera images, and not necessarily because it’s successfully identifying locations purely based on the landmarks in the image.

> I realized that the AI was using the smudges on the camera to help make an educated guess here.

This is a coordination failure. We have ways to distribute the source, but not the reviews. Every time someone does any level of reviewing that should be publishable too.

Things like cargo-crev [0] or cargo vet [1] aim to tackle a subset of that problem.

There’s also alternate implementations of crev [2] for other languages, but I’m not sure about the maturity of those integrations and their ecosystems.

My university had a model train set, hooked up to some ancient 386 machines (and we're talking late 2010s here) and it was used for a real time programming course which was taught in Ada.

Unfortunately the lecturer that ran the unit retired the year I started my degree and by the time I had the prereqs required to do the course the faculty had run the course once without the original lecturer and it was apparently a disaster so they canned the unit until it could be rewritten from scratch, sans train set ... and in Java.

I still think about missing out on programming a train set. Years later

The University of Waterloo has a similar course, CS452: Real-time Programming.

It’s not quite the same as having physical access to the train set, but a student eventually wrote a simulator for the Märklin train set [0]. Another student wrote an emulator for the TS-7200 used for the class [1] if you don’t want to test your kernel in QEMU.

I don't own AirPods, but one of the things that I've struggled with after the proliferation of headphone jack removal is that on all the Bluetooth headphones/earbuds I've tried the lowest volume setting is still too loud. I normally use Shure SE215s wired, but I've tried the Sennheiser PXC550, Sony WH-1000XM3, Jabra Elite 7 Sport with similar impressions, and tried using my work 2021 MacBook Pro as the audio source instead of my phone. Surely I'm not the only one who feels this way?

On my Samsung phone, I've had to manually set individual app volumes to 80% via Sound Assistant, have additional volume steps enabled, and have the system sound set to the lowest setting when using Bluetooth.

Are they even accurate enough to be useful? Today my Garmin watch told me I was at 85% in the middle of the afternoon when I was feeling pretty good and 100% towards the end of the day when I was feeling a bit tired.

The way I understand it, and I could be totally wrong, that’s somewhere between dead and impossible within the span of 2 hours.

Rob ter Horst's (The Quantified Scientist) test results compared against a fingertip pulse oximeter—which include at ground level and on flights—seem to indicate that they're okay for detecting whether your SpO2 readings are normal/abnormal. Basically it seems that if you get a one-off abnormal reading then it's possible for it to be a false positive, while you're unlikely to consistently get false positive results.

See the video for the Apple Watch Series 6 [0], and Series 7 [1].

There's also tests for the Series 8 [2], although it doesn't include data collected in a low oxygen environment.
