etskinner··on The Sound Proof Booths of Silence
Read the article; The last couple paragraphs talk about how they tried that and it didn't live up to their standards
etskinner··on Bacteria generate electricity from wastewater
How exactly do you 'wire up' E. coli bacteria? Is the idea here that we could somehow string a bunch of them together into a tiny battery? Or is it more like using them as the electrolyte in a battery?

etskinner··on ToDesktop – Web app to desktop app in minutes
This is true. One thing people have trouble with, though, is committing time to develop a desktop version of their app. So the shortcut is tempting, but you're right that it's not ideal. Often, a poor desktop app is better than nothing.

This is very close-minded thinking, it's very possible life doesn't require cells

etskinner··on NASA, DARPA enlist Lockheed to build nuclear-powered spacecraft
"Using an onboard nuclear reactor fueled with high-assay low-enriched uranium (HALEU), nuclear thermal propulsion systems heat hydrogen propellant and funnel released gasses through a nozzle."

What could go wrong?!

If you have an explosion mid-flight, wouldn't this turn into a dirty bomb?

etskinner··on Wavy walls use fewer bricks than a straight wall (2020)
There's actually a similar concept in 3D printing called gyroid infill, it's essentially a 3D version of the wavy wall:

etskinner··on S&P500 Normalized with M2
They should really be comparing to the total stock market, of course. Using something like DWCF or VTSAX
etskinner··on S&P500 Normalized with M2
It would be more helpful to compare S&P 500 vs CPI rather than M2. It's purchasing power that matters to most investors, not the comparison to how much money exists.

S&P 500 gained ~40% since January 2020, and CPI gained ~18%.

Even better would be comparing to the total stock market rather than S&P 500. Using something like DWCF or VTSAX

etskinner··on DJI Drone Rescue Map
I absolutely love this idea, I'm surprised it hasn't become popular in the amateur radio / Lorawan communities
etskinner··on AGI Simulator
It's the total accumulated knowledge, I think.
etskinner··on To save money on insurance, drivers agree to intrusive monitoring technology
The article you linked is specifically talking about particle emissions, not anything gaseous. If it included the negative externalities of all emissions (CO2, NOx's too), it might paint a different picture.

etskinner··on Reddit permanently bans account of user advocating Lemmy migration
People might want to avoid having the same thing happen with a reddit clone 10-20 years in the future. Federation allows communities to decide their own fate instead of having decisions handed out from on high
etskinner··on Ask HN: Are there any 5G feature phone out there?
Probably because the only things you can do on that phone are things for which there is a feature. That's what distinguishes it from a general purpose (smart) phone. Similar to the distinction between general purpose computer vs an embedded system.

Slightly more like the Jeep Problem: https://en.m.wikipedia.org/wiki/Jeep_problem
etskinner··on Minnesota Passes Right to Repair
This might be a "don't let perfect be the enemy of good" situation. It might be that it was too politically risky to include those categories, so they did the next best thing.
etskinner··on Ask HN: Where have you found community outside of work?
For those who aren't religious, there's also Sunday Assembly: https://www.sundayassembly.org/

For those who are spiritual but not Christian, there's also the Unitarian Universalist Association: https://www.uua.org/

etskinner··on Tesla rethinks the assembly line
The article alluded to the idea that reducing floor area and would reduce the cost of getting parts to the right place. If your process is 500 feet long instead of 1000 feet long, you just made your material handling workers up to twice as productive.

etskinner··on Tape Storage Trundles On, Increases Yearly Volume to 128 Exabytes
It does, actually. Most encryption schemes have the property of ciphertext indistinguishability: https://en.wikipedia.org/wiki/Ciphertext_indistinguishabilit...

If they didn't, they'd be vulnerable: https://en.wikipedia.org/wiki/Distinguishing_attack

However, something close to your point is true. If they compress the data and then encrypt, the ciphertext will indeed be smaller than the original data.
