n40487171··on Microsoft's CFO FIRE journey to retire at 44
An ER could easily triage people into an urgent care wing of the hospital, but hospitals don't have those. Because they don't have any incentive to provide anything resembling cost effective care.
n40487171··on Webb discovers new feature in Jupiter's atmosphere
Spectrometers don't always make "images", it's possible they didn't take a picture?

Also, that deep field has some amazing gravitational lenses!

Don't doubt that Walmart tracks users/shoppers in depth: https://www.bloomberg.com/news/articles/2023-10-04/walmart-s...
n40487171··on Using Goatse to Stop App Theft
Did you read the xkcd? It's not about goatse
n40487171··on Histotripsy – a technique that harnesses soundwaves to attack cancer
The wave would be focused by the transducer (analog of a lens) so that the energy flux is highest at the focal point and presumably low enough not to cavitate outside the focal area. I.e. magnifying glass and the sun kinda thing.
n40487171··on Histotripsy – a technique that harnesses soundwaves to attack cancer
It's not that kind of sound healing.
n40487171··on OpenAI is exploring making its own AI chips
It sounded like they weren't training but they were trying to figure out what gpt-5 structure, tooling, and training data will look like
n40487171··on OpenAI is exploring making its own AI chips
I was just thinking the inference cost could be reduced by making hardware with less error correction in specific areas to get higher density, and let the NN work around the limitations.
n40487171··on Rivers are rapidly warming, losing oxygen; aquatic life at risk, study finds
Blue-green algae will fill that void, and those living in affected areas will need to use activated carbon water filters.
n40487171··on The washing machine in my ear, and an empty boat
Happened to me before, I thought it was a generator running at a construction site down the street. It wasn't that long ago but I don't recall exactly when it stopped or if anything correlated.
n40487171··on The Antagonists: The rise and fall of type-in text games
It's bear upside down!
n40487171··on Human-powered air-compressor and energy storage system
I would guess that it would be a metal spring of some sort that doesn't lose energy to thermal side effects of compressing and decompressing gas, for a higher round trip power efficiency. Or else it could be a relatively large gas reservoir so that it doesn't heat or cool the gas too much.
n40487171··on 40 years ago yesterday Air Canada Flight 143 ran out of fuel mid-flight
Roll inertia estimation from aileron performance, to gauge wing tank levels? Have to assume ailerons are performing 'nominal'.
n40487171··on Electric bike, stupid love of my life
I feel like a paintball gun on a shoulder strap might help to discourage that behavior from motorists
n40487171··on Human-powered air-compressor and energy storage system
I believe those use a hydraulic accumulator system rather than compressed air.
n40487171··on Everything that uses configuration files should report where they're located
Yes but wouldn't the logging take up quite a bit of memory? Something like O(compute cycles* (log(lines of code)+log(memory allocated))) before compression.
n40487171··on China solar module prices keep diving
Regulatory capture by electricians
n40487171··on Full ignition for ESA’s reusable rocket engine
The cern tour is really cool. They actually take you to see the instruments where possible. Got to see some huuuge copper busbars that they use to dump current from the electromagnets. And got to see some sections of the main tube that were in the repair area (maybe they were display units).
n40487171··on Humans have pumped enough groundwater to change the tilt of the Earth
I think you may be looking for some sort of Nihilism
