etskinner··on Electricity from Space: The 1970s DOE/NASA Solar Power Satellite Studies
They address this in the article: Only twice per year are the panels in shadow, at the equinoxes. Presumably all the rest of the time they're slightly above/below the earth with respect to its orbit. It's the same reason the moon is lit nearly all the time.
etskinner··on “Off switch” makes explosives safer
Presumably there would be more safeguards in place than just the water. All the safeguards that currently exist could still be used.
etskinner··on Lo-Fi ATC
The human ear doesn't really have the ability to determine the height of a source reliably, only left/right. A better effect might be putting the audio out of phase on left/right, which usually has the effect of making it difficult to hear where the sound is coming from (it kind of makes it sound like it's omnidirectional like you mentioned)
etskinner··on America Is Trying to Electrify. There Aren’t Enough Electricians
Asking for a friend: Would it be a good idea for the average jaded tech worker to learn to be an electrician? Why or why not?

Pretend we're talking about someone on the low end of programming knowledge, the kind of tech worker who might be made obsolete by AI.

etskinner··on How seawater might soak up more carbon
Acidification is due to the water holding more carbon dioxide (carbonic acid) than baseline, right? This proposal is to turn carbonic acid into calcium carbonate, which 'removes' the carbonic acid from the water. So this would reduce acidification (at least until the water absorbs more carbon from the atmosphere). Am I missing something?
etskinner··on EVs Are Essential Grid-Scale Storage
What's hard about being both a house backup and a grid feeder? Seems like all that's needed is a smart transfer switch
etskinner··on Mazda has tested a synthetic fuel in an unmodified MX5 on a 1000-mile road trip
I too was frustrated that they didn't say what the fuel was. It led me to believe that it's ethanol too. They just didn't want people to see the article as the nothing burger that it is.

I looked at several other sources covering this and they're all similarly quiet about what the fuel actually is. Looking at they supplier's (Coryton's) website, they boast about 'bespoke' synthetic fuels. So I'm guessing it's Mazda that's being shy about the details.

etskinner··on .bestbuy
I don't understand, what do you mean by your link?
etskinner··on Relaying Yubikeys
Presumably you would trick the person into touching the key. Similar to getting someone to put their password in with a phishing attack.
etskinner··on The coming tsunami of fakery
There's plenty of influence plays there. If I worked for Cloud Provider X, I might nudge people toward using that cloud instead of a competitor. If I'm a developer of Software Y, I might say "Software Y makes this much easier" and boost sales.
etskinner··on The West's historic drought is threatening hydropower at Hoover Dam
More cooling towers would mean more water needed, since they rely on evaporating water. With river levels already low, I bet they're cautious about using more water.

I wonder if they're considering refrigeration, or if that's even feasible. Conceivably, you could use the power from the nuclear plant to cool itself, since refrigeration has a higher-than-1 coefficient of performance.

etskinner··on The West's historic drought is threatening hydropower at Hoover Dam
It seems likely that they simply designed it for a max expected water temp and they're exceeding that max. If you need more water to cool the same amount, you're gonna need some bigger pipes.
etskinner··on [dead]
I can only imagine that the way the scientific community is reacting to this is similar to back when Copernicus concluded that the solar system is centered about the Sun, not the Earth. It's really really hard to shake your preconceived notions in the face of contradictory evidence.

Red/green colorblind people will have trouble reading this version
etskinner··on The World Excel Championship is being broadcast on ESPN
Just learned about pyspread[0] from your comment, it's surprisingly powerful. I'm well-versed in Python and in Excel, and I'm already more comfortable in pyspread than in Excel after 10 minutes.

etskinner··on Ask HN: Google Search down?
They kind of do store the internet though, don't they? They store a cached version of most pages.
etskinner··on How the US Postal Service reads terrible handwriting
It would likely fall back to the individual mail sorting centers to manually sort them, just like they said happens if the people keying don't respond fast enough (I think they said within 60s or so).
etskinner··on Tricks to start working despite not feeling like it
You could conceivably still make yourself an out for that. You could have an excuse for hanging up ready to go. Or, if you're talking in person, there are probably several apps that allow you to receive a fake phone call, and step away.
etskinner··on I used DALL·E 2 to generate a logo
It's a loan word, there isn't any 'correct' or 'incorrect' answer. Language is always evolving, which is why dictionaries are often descriptive instead of prescriptive.

etskinner··on How far can you go by train in 5h?
Zillow doesn't have isochrones, for one.

I long for a map experience that's more like a SQL query than a catalog, and Zillow's filtering leaves a lot to be desired.

etskinner··on That time when I accidentally social engineered myself to a film set
How does that fix the issue where someone is on a week-long vacation? Seems like a letter a few weeks in advance is they least they could do.
etskinner··on RustDesk – Open-source TeamViewer alternative
What would stop someone from setting up a server that listens for connections? Kind of like a reverse VNC (or, by extension, reverse ssh tunneling). It may not be a feature of the program yet, but that doesn't mean it isn't possible. I could compile and distribute my own binary that automatically connects to me.example.com:1234, make sure that server is accessible from the internet, tell the user to bypass non-signed executable restrictions, and we're good to go.

etskinner··on SIM Cards Are Going Away. Why That’s a Good Thing
There seems to be a lot of FUD here, but I'll just chime in with my personal anecdote: I've been using eSIM functionality for a couple years with 0 issues whatsoever. The Google Fi workflow is basically just to log in and it's automatically set up. The Mint Mobile workflow is just 'get a barcode in your email and scan it from your phone'. I assume others are similar.

The only use case I can think of where any of that breaks down is where you're in a situation where you broke your phone AND you don't have internet access. But as far as I'm concerned, a visit to your neighbor or local library is enough to fix that.

etskinner··on Investigating the effects of bike lanes in Minneapolis
Anecdotal, but: Yesterday I rode on the Midtown Greenway, chain of lakes paths, Mississippi River Trail, and Minnehaha Creek trail in Minneapolis. They each serve as a big artery to access various semi-urban parts of the city. You'd be surprised how many people are out biking. Each of those trails have a road that runs parallel to them, and there are consistently more people on the trail than on the road. Meanwhile, the trails take up half the space of the road, and spacing between bikes can be much tighter. Each of those bike trails also has a nice pedestrian path running parallel. I'd estimate the portion of the nearby population utilizing either the bike or pedestrian trails is more like 20-30%

I agree that improving bus infrastructure would be a huge help, but that's not mutually exclusive to improving bike infrastructure. If you haven't experienced biking in Minneapolis, please visit some time! Try our bike share bikes, and the trails above, and see for yourself.
