The general pattern with these sorts of things is that it's a combination of temperature and time. For any given microorganism there's some temperature it thrives at, some temperature at which it will start dying and if left for l

This is an entirely predictable consequence of Goodhart's Law [0] and Google ought to have known better. I can believe that Google was genuinely trying to help their users by providing more useful search results, yet, due to Goodhart&#

There's nothing wrong with refining models, but it's a bit besides the point. At a 1995 Planetary Defense workshop Edward Teller proposed the development of a 1Gt device for that purpose. Fusion bombs are actually quite straightfo

Tesla already tried that, years and years ago. They built a fully automated battery swapping station for the Model S, as a test of concept, and nobody used it. So the program was abandoned as a complete failure, and now Tesla's newer m

As a regular reader of Matt Levine this sounds like an opportunity for a securities fraud suit. Surely Amazon has said that its factories follow local labor laws, that whistleblowers are protected etc. That seems like a fairly standard thin

It's curious that you say RTT is mostly random noise yet BBR gives you only 45 Mbps. The whole idea of BBR is that it probes bandwidth vs RTT and finds the point at which RTT starts to increase. Maybe BBR is just misbehaving due to too

I think it's worth taking a look back at X10 [0], the OG home automation. Yes, it was primitive by today's standards with a very limited command set, but that command set was good enough for 90% of purposes and its simplicity mean

Leaving aside whether the number of deaths claimed by the article is correct, it is incorrect to directly compare deaths of infants with those of the elderly. It should be done using Life-years lost [0] or Quality-adjusted life years [1]. [

If that's the point you're at just learn the sheet bend. It'll suffice for 90% of purposes. There's a reason it, alongside the bowline, are considered probably the two most important knots to learn. To answer your questi

It's also worth mentioning the Ian knot [0]. It's just a way of tying the standard square knot, however in the convention established by Clifford Ashley [1] a knot consists not only of the topological configuration, but also the m
