ramidarigaz··on Does that use a lot of energy?
> 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

ramidarigaz··on Ian's Shoelace Site
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

ramidarigaz··on Cold restart whole system after total outage
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

ramidarigaz··on NASA returns Hubble to full science operations
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' :)
ramidarigaz··on Hallucinations re: the rendering of Cyberpunk 2077
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.
ramidarigaz··on Experimental blood test detects cancer up to four years before symptoms appear
Azra Raza was also on the Mindscape podcast, really realy good interview.

ramidarigaz··on Tesla Model 3 represented over 15% of September new car sales in The Netherlands
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).

ramidarigaz··on Astronauts escape malfunctioning Soyuz rocket
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.
ramidarigaz··on Introducing Remembear, new password manager
If any of the Remembear developers read this, I'd love to put in a request for a Linux client!
ramidarigaz··on Cooling the Earth with a cloud of small spacecraft near the inner Lagrange point
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.
ramidarigaz··on Four Earth-sized planets detected orbiting the nearest sun-like star
Kepler has only focused on two tiny patches of the sky in its lifetime IIRC.
ramidarigaz··on SpaceX plans worldwide satellite Internet with low latency, gigabit speed
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.

ramidarigaz··on The problem with p-values
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.
ramidarigaz··on Blockchain Healthcare 2016 Report – Promise and Pitfalls
And that seems like a totally rational fear too.
ramidarigaz··on Announcing 10x donation matching on Watsi
Watsi? It's a pretty well-known charity around here at least. I believe it's a YC-backed nonprofit.
ramidarigaz··on Google’s become an obsessive stalker
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?
ramidarigaz··on Robocalls have triumphed over the Do Not Call list
The companies that run them do.
ramidarigaz··on John Carmack's BAFTA Introduction, Speech and Interview [video]
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.
ramidarigaz··on AlphaGo beats Lee Sedol again in match 2 of 5
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.
ramidarigaz··on Alphabet Becomes the Most Valuable Public Company in the World
That might not include after-hours trading prices. Not sure about that though.
ramidarigaz··on SpaceX Falcon rocket explodes on landing after delivering satellite to space
Estimates I've heard say 15% loss of payload mass for a barge landing, 30% for land.
ramidarigaz··on Concepts for Your Cognitive Toolkit
I believe the title is actually "Rationality: From Ai to Zombies", unless you're referring to something else.
ramidarigaz··on CVE-2015-8126: Multiple buffer overflows in libpng
I wouldn't be surprised if this is from AFL.
ramidarigaz··on Beware of ads that use inaudible sound to link your phone, TV, tablet, and PC
Chromecast can do ultrasonic pairing.
ramidarigaz··on FastMail under DDoS Attack
Bummer to hear that :( Keep up the good work! I'm a very satisfied customer, and I wish you all the best.
ramidarigaz··on Helping my students overcome command-line bullshittery (2014)
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.
ramidarigaz··on Show HN: Cancel your Comcast in 5 minutes
When I called to cancel my account I told them I was moving out of the country. Total lie, but it made the cancelation process really easy.
ramidarigaz··on Electrifying flight: very different aircraft may end up taking to the sky
Like electric cars, they have that nice abstraction layer where you don't _have_ to depend on fossil fuels. Just provide solar charging!
