"If they do not, cryptographers have shown, then secure cryptography is impossible." It seems like they're using "secure cryptography" kind of narrowly, as AFAIK a one-time pad could still be secure without any kind

Maybe "turned inside out" isn't getting the right idea across, since the "inside" of an orifice is still a continuation of the outside surface of the organism. Instead picture one of those cabinets with the built-in

Could the opposite spiral directions be just roughly the same structure but one is turned inside out? I’m not up to speed on topology but generally turning things inside out changes the “handedness” (cf. a glove).

I end up using the built-in emacs key bindings a lot (they also work in many shells). Ctrl-k (cut to the end of the current line and save it in a special secret extra clipboard) and ctrl-y to paste Ctrl-e to go to the end of a line, ctrl-a

(My academic background is engineering, not computer science, so I'm quite possibly wrong about all of this) I think what OP is assuming is a multi-threaded or multi-process environment, where the calling function can just block whatev

I see three problems with that explanation. First, I'm not sure there's a strong case that our lifestyles today are any more sedentary than in, say, the 1970s (when obesity rates were around 12% rather than 30%). We had cars, tran

There are some interesting coincidences that make me think that the torpor hypothesis might be worth exploring: - Basal metabolic rates in present-day Americans are substantially lower than they were in the past ( http://webcache.

I'm USian by birth, my parents were both born and raised in Germany, and my partner is Canadian. I've spent most of my life in NW (lower-48) USA and far-western Canada. As a median middle-class person, Canada is pretty clearly the

I can definitely relate to the "I wish we could just cancel the trip and take two weeks to relax at home" sentiment, pre-departure. At the same time I'm almost always retrospectively glad that I went on any given trip. I ofte

My read is that the author is using "experience" to mean "something produced in a low-productivity sector" and "thing" to mean "something produced in a high-productivity sector", which is definitely a

At this point they're talking about an e-motorcycle that sort of incidentally has an emergency backup pedal drivetrain. Which is fine—most of the energy efficiency advantages of a bike come from being light and (relatively) slow, not f

There's a similar phenomenon in cordless power tools. Each one comes with its own proprietary connection and hence tools and charging system. There does seem to be a variation on the "give away the razors to sell the blades"

Water is a pretty amazing heat carrier. I did a bit of poking around for a project idea and couldn't really find anything with a higher heat capacity, at least for things that don't undergo a phase change. I wonder if there's

I live around 49°N and get an average of ~3 hours of rated output per day over the course of the year. OP's is closer to 1 hour per day. My array does have a clear view of the southern sky, and the angle is supposedly ideal for a fixed

You're both overgeneralizing and overstating the case here. PV is superior to solar thermal in a number of important ways, and grid-tie systems can be extremely cost-effective relative to storage. The article here https://ww

I've heard (but not verified) that ibuprofen is a vasoconstrictor like caffeine, and can be more helpful in easing withdrawal symptoms than other OTC pain meds. That said, it's likely also tolerance-inducing ( https://ww

Forgot to add that it steers a lot of investment into a zero-sum speculation game that could be going into investments that create (rather than transfer) value.

I think this is one of the biggest drags on the economy of the anglosphere, along with healthcare costs (which on some level could be connected). The cost to construct brand new housing is considerably under US$100k per person where I live

I don't really know if there's a firm consensus as to the official nominal voltage of a lithium ion cell, but I was going off of 10 cells (in series, aka "10S") being considered a 36V system (that gets up to ~42V when fu

If you're remotely interested in this sort of thing, definitely check out the VESC project ( https://vesc-project.com ), which is kind of the secret sauce that makes this sort of thing accessible to mere mortals. There are a

There are a lot of practical problems trying to build a balancing vehicle around an internal combustion engine. They can't produce any torque at zero speed, they can't smoothly reverse direction, they likely can't produce eno

Even when they have a dedicated signal and plenty of time, I'm surprised at how terrible most drivers are at turning left (US/Canada perspective here). The standard approach seems to be, as soon as they enter the intersection, to

by frankus 5y ago
The tradeoff with that is that you end up with more than one lane per direction, which works fine with signalized intersections, but is unsafe at non-signal-controlled crosswalks. Without a traffic light, a car in one lane will stop for a s

> "what kind of diet will allow me to eat less calories in the easiest way" I think this is still kind of missing the point about why people think that the EBM is unhelpful. Intentionally eating fewer calories to lose weight is

I'm a bit more skeptical of the CIM than I was in the past, but the EBM to me just seems hilariously inadequate to explain the obesity crisis. It's like if a patient came to their doctor complaining of water retention, and the doc

I totally agree, but as someone who has a lot of flexibility to set my own schedule I probably don't have as much awareness of the pain points of the current system. The reality is that days get too damn short in the winter and any sys

The whole point of time zones is to make it somewhat close to noon when the sun is at its peak, and do make midnight somewhat close to the middle of the night. Otherwise we should all just use UTC. That's my main objection to permanent

It’s worth remembering that for a lot of “A to B” trips the change in location is kind of incidental to the actual goal of shopping, socializing, dining out, etc. In other words you if locate a lot of “B”s close to your “A” (or vice versa)
