> Whenever you do the real world calculation for what an electric cars CO2 profile looks like it turns out to be the same as a gasoline car unless your country is majority nuclear.

Not at all true: https://www.carboncounter.com/

US-specific but you can even pick a state and it will use the generation mix of that state

I switched to the secure knot after finding this site a few years ago https://www.fieggen.com/shoelace/secureknot.htm

It's really excellent, my shoes never come untied and I don't have to double-knot

Interestingly this paragraph isn't quite true:

> So much of the modern world depends on our mastery over materials (to make a precision screw, you need a precision-machined harder material—diamond / titanium—to work on a softer material—steel), and our ability to turn rotary motion to linear motion (it's stupidly difficult to reliably precision-machine a harder material without even more precise linear + rotary motion—lathe/CNC machine). Hence, a bootstrap problem.

Steel is hardenable (or rather, some steels are hardenable), you can change its hardness through the specific application of heating and cooling. So you can make a crude tool with relatively soft steel, harden it, and use it to make a more precise steel tool (again machine soft, then harden). This does make the bootstrapping problem a bit easier, I think. Although not easy in the absolute.

See https://www.youtube.com/watch?v=V_Mp1fNzIT8 for a great dive into primitive steel hardening techniques.

For anyone that hasn't encountered Technoblade so far, the Great Potato War is an excellent place to start: https://www.youtube.com/watch?v=5qjnDd1rsII

Fuck cancer

Sure lots of organizations have unique capabilities, and SpaceX is one of those! Better to bring home Hubble than let it burn up once it's no longer operational. I definitely rate inspiration much higher than 'dubious' :)

Disagree about DLSS being cheap marketing trash. Especially on the quality or balanced settings, it produces a significant framerate improvement in Cyberpunk without any noticeable quality loss.

Azra Raza was also on the Mindscape podcast, really realy good interview.

I had no idea electricity was so expensive in NYC. Also, I think 3 miles per kWh is a bit pessimistic. Lifetime average for my Model 3 is 260 Wh/mi, which works out to 3.8 mi/kWh. Given Colorado's ~$0.11/kWh, it all works out to just under $0.03/mi which looks a lot more favorable against the other options. It's still a heckin' expensive car though.

The NASA TV feed seems to be higher quality than youtube (and has identical content).

There are only three right now. The usual procedure is to have enough Soyuz capacity for everyone on the station, so when the station has 6 people, there are two Soyuz.

If any of the Remembear developers read this, I'd love to put in a request for a Linux client!

The inner Lagrange point is always between the sun and the earth (by definition), so the "shadow" would always be centered on local "noon" and would pass the each longitude at the same time every day.

Kepler has only focused on two tiny patches of the sky in its lifetime IIRC.

This[1] article does a nice job of covering the subject, but in essence, laser-based communication between satellites has been done and it works pretty well.

I think there is a good option for choosing your priors in the Earth/Sun problem you mentioned. Just put them at 50/50. That's basically stating that you have no preference for one theory over the other, and it allows for any evidence you gather to be maximally effective in computing the posterior.

And that seems like a totally rational fear too.

Watsi? It's a pretty well-known charity around here at least. I believe it's a YC-backed nonprofit.

What? Existential in that it could literally end our species? Nuclear war and climate change sure, but info collection? How is this not totally hyperbolic?

The companies that run them do.

Honestly all of his talks are this good. He's really an incredible speaker, and it seems like he mostly speaks from an outline, not a script.

Michael Redmond. I thought he was excellent too, and I really liked his willingness to jump into hypothetical situations and play it out. Really, really good commentator.

That might not include after-hours trading prices. Not sure about that though.

Estimates I've heard say 15% loss of payload mass for a barge landing, 30% for land.

I believe the title is actually "Rationality: From Ai to Zombies", unless you're referring to something else.

I wouldn't be surprised if this is from AFL.

Chromecast can do ultrasonic pairing.

Bummer to hear that :( Keep up the good work! I'm a very satisfied customer, and I wish you all the best.

Oh god I can't stand ROS. I had to use it for a school project and it drove me insane. The project requirements had us using it on a Raspberry Pi, and the startup times were intolerable, for no apparent reason.
