Conventional ways to do this include casting or, as is done on the RL-10 and SSME, building the nozzle out of thin-walled tubes (very labor-intensive and expensive). 3D printing is the future here, but there's still lots of improvement required in terms of wall thickness and roughness control, not to mention build volume.

> Are you really saying that making non-consensual porn just such a deep biological need that nothing can be done?

I think what he is saying is that if you ban pornography, the only people who can make it will be criminals---and criminals will commit further crimes as (a) there is no psychological barrier to them doing so and (b) their 'consumers'/'customers' are already consuming illegal material, so can unsurprisingly further fetishize criminal behavior.

It would be better/easier to allow for pornography but strictly regulate it to a degree that incentivizes the moral production of it.
I'm Japanese-American.

I suspect that’s the key right there. From friends who are the same, I get the impression that in Japan if you’re of Japanese descent the expectations had of you are very different than the typical gaikokujin.

I would say the blade analogy is fairly correct.

OSS isn't polished many times. The installer might be missing. Documentation is out of date or incomplete. The plug-in manager requires using the file system explorer directly.

Oh boy have I tried just about everything. I've settled on a pretty nice solution: markdown files in my Dropbox directory. To edit them I use iA Writer (paid but worth it) for a very nice markdown exciting experience without any special serialization format like all the others (just plain markdown files). I also use their Android app but for both platforms I could switch to any other app that edits markdown files. Total portability. Syncing is Dropbox's job.

Seems I must have messed something up in the initial testing. Now it outputs rol with uint8_t too. Well, that's good to know.

For the record, here was what I was testing:

#include <iostream>

uint8_t rol(uint8_t x, uint8_t c) {
return (x << c | x >> (sizeof(x) * 8 - c));
}

int main()
{
volatile uint8_t a = 0b01010000;
volatile uint8_t b = 3;

uint8_t c = rol(a, b);

std::cout << static_cast<unsigned int>(0b10000010) << std::endl;
std::cout << static_cast<unsigned int>(c) << std::endl;

return 0;
}
I think you mean MAD - Mutually Assured Destruction. Although a patent-war MUD (multi-user dungeon/domain) might be an interesting premise.
It's not as if it created an illegal market for it either. Unless everything in the world is permitted, there will aways be an illegal market for something even if only because people want to dodge regulations.

The total ban does mean that only criminals can produce pornography, and criminals by their nature don't have the moral qualms with committing further crimes.

According to accepted psychological research ... it does. Well, not murderous, as that sort of research would never get approved.

But aggressive ? Certainly.

Why can't people accept this ? It's the very idiotically basis of how the human mind works: it learns. 99.99% of the time it learns by imitating something else. Give it something violent to imitate (no matter how artificial, fake, drawn, ...), and ... surprise ! It will come up with more violent answers in the future. How is this strange or unexpected in the least ?

And yes, I get it, you feel like you are in control of your own mind. By the way, how do you explain how advertising works if that were true ? Or the obvious influence mass media have ? Or why absurdly large groups of people keep coming to the same conclusion (from culture, to political "winds", to google searches ... all shows strong correlations between huge groups of people).

Now granted, this is results like 10% more likely to use minor violence in a "get something taken from me" situation among children (the other alternative generally being getting adult help, which may or may not cooperate depending on the study). None of those studies are saying Rambo turns toddlers into terminators. But objectively, measurably more violent ? Yes, yes it does. It does so heavily in the short term (hours), then the effect slowly dies down (but it's still significant 20 years after the exposure).

This has been incredibly thoroughly tested and yes, we are VERY sure this does in fact happen.

I naively thought modern systems used a battery of lidar (with different wavelengths to provide redundancy, like visible+ir+uv) to create a precise 3d map of the objects around the car. Coupled with cameras for visual awareness this seems like the only sane system.
There is a weak correlation at best.

One of my open source projects has almost 5K stars on Github so I should be preaching with the choir here but that would be disingenuous.

I think that a lot of it comes down to having perfect timing... The kind of timing that only dumb luck can deliver.

Building a decent quality project is just the baseline requirement...

Saying that project quality or usefulness is the determining factor to achieving popularity in open source is like saying that having a pair of legs is the determining factor to being qualified for the 100m sprint in the olympics.
Linux Apps (Crostini) Headed to a Lot More Chromebooks
In the traditional medicine system of India (Ayurveda), there is an anecdote passed around that goes something like this: for each hour of sleep before midnight, count it as two hours. For each hour of sleep between midnight and sunrise, count it as one hour. Sleeping after sunrise counts for zero - it is useless.

And I've observed this to be true in my life. The most peaceful, restful sleep I experience is consistently between 10pm and 1am.

I fully agree with your dismissal of hours slept being the quantitative unit of sleep, and I'm similarly curious about what constitutes a healthy, effective sleep habit...

You know my performance might change imperceptibly with sleep, but the area where I know it makes a difference -- probably the most important area -- is how nice I am to fellow human beings.

I am a better co-worker, family member, client etc with sleep.

As noted by @georgecmu, drones for mapping underwater caves have been used for many years--evolving to autonomy from hand-held & scooter-mounted LIDAR mapping arrays. Barbara am Ende wrote a 2001 article in Computer Graphics on such efforts (paywalled: https://www.computer.org/csdl/mags/cg/2001/02/mcg2001020014.... ). I am aware of a variety of drones that have been deployed in air-filled caves too--from cameras on balloons (tall chambers with high leads) and standard copter drones to rubble-searching robots. Tethered cameras are occasionally used to evaluate obstructions (e.g. narrow cracks and breakdown). Overall, though, in-person exploration is satisfying and compelling. Robotic tech in air-filled caves mostly is used either for demonstration purposes or, in rarer cases, to determine the best locations to exert more human effort.

Another branch of study is the discovery of subsurface voids from the surface using ground-penetrating radar, microgravity,
electrical resistivity, or other geophysical methods. A robot could be equipped with the sensors in dangerous or inaccessible locations, such as off-planet or war zones. DARPA had an interest in this in the early 2000s to locate hostiles in caves, though I do not know its current priority.
not completely true that they could just print the money and demand no tax. Without demanding tax payable in the government's currency then nobody would have any reason to use that currency and the currency would have no value.

>But this is of course the "very persistent illusion." The reality is humans are group think machines, carefully evolved to carry out distributed cognition (language, consciousness -- which is always of others).

First, this presupposes ("of course") what it should prove.

Second, even if humans are indeed "group think machines, carefully evolved to carry out distributed cognition" that doesn't mean they arrive at a more accurate description of reality via that method -- just that this way of "group thinking" is evolutionary more advantageous.

A view that is accurate and one that has evolutionary fitness are not necessarily the same thing.

In fact, they can be the very opposite. E.g. an animal that inaccurately considers all instances of another group as one and the same based on limited prior experience (e.g. as enemies) will be more likely to survive that one that tries to accurately gauge what the intentions of each new member of the other group it meets actually are.

To quote Nietchze:

"Where has logic originated in men’s heads? Undoubtedly out of the illogical, the domain of which must originally have been immense. But numberless beings who reasoned otherwise than we do at present, perished; albeit that they may have come nearer to truth than we! Whoever, for example, could not discern the "like" often enough with regard to food, and with regard to animals dangerous to him, whoever, therefore, deduced too slowly, or was too circumspect in his deductions, had smaller probability of survival than he who in all similar cases immediately divined the equality. The dominant tendency however, to treat as equal that which is merely similar - an illogical tendency for there is nothing equal - is what first created the whole basis for logic. It was just so (in order that the conception of substance should originate, this being indispensable to logic, although in the strictest sense nothing actual corresponds to it) that for a long period the changing process in things had to be overlooked, and remain unperceived; the beings not seeing correctly had an advantage over those who saw everything "in flux" In itself every high degree of circumspection in conclusions, every sceptical inclination, is a great danger to life. No living being might have been preserved unless the contrary inclination to affirm rather than suspend judgment, to mistake and fabricate rather than wait, to assent rather than deny, to decide rather than be in the right had been cultivated with extra ordinary assiduity. The course of logical thought and reasoning in our modern brain corresponds to a process and struggle of impulses, which singly and in themselves are all very illogical and un just; we experience usually only the result of the struggle, so rapidly and secretly does this primitive mechanism now operate in us."
Driving AI at Higher Speed into the Enterprise
I've driven a rental with those features as well, and in my experience at least the Prius version is almost a little oversensitive to brake lights. In adaptive cruise mode, I've had it kind of slam the car's brakes pretty hard just because another car not even in my lane tapped their brakes to make an exit.

Of course, I'm not going to test it against stationary objects at high speeds, but at low speeds it definitely gives escalating warnings before you hit the door or wall of a garage. As someone who dented a garage door once, I value this feature.

An initial downvote -- fair enough. For there are political and other tones to my comment. But, since the OP introduces the topic of sport, in the first place, some of the things I see in American football that lead to my comment -- and that cause my concern for the U.S.:

- Players destroying their bodies (and, we increasingly know, minds) for the sake of the sport.

- A willful blindness to the above, served at top levels by rampant commercialism and profit, for decades. Even the cognitive effects, probably for a couple of decades if not longer.

- A fan base that spends an inordinate amount of time in such allegiance and paying fealty. Granted, there's a lot of socialization around this. But there's also a lot of... well, several words come to mind, but I'll sum it up with "aggression", often I find of a rather mindless and inconsiderate sort, at least from a minority but a minority having an outsized impact.

- Most recently, when the "show" is co-opted to express another viewpoint: The protests. So much allegiance to the show and disinterest in paying attention to what the players, the participants who actually make the show possible, are rightly trying to point out -- something that belongs to many of their own backgrounds and experiences.

Blind allegiance. Stop and think about the context.

P.S. I know European football has a lot of violence -- those stories about fan violence and absurdity. But I don't feel qualified to speak to it, really. I also don't perceive the players as being quite so chewed up by the game, although I vaguely recall some stories of arthritis and significantly limited mobility. And headers are becoming increasingly suspect in brain trauma.
If we're doing radical changes to the tax structure, land-value taxes have far better side-effects than consumption taxes.
I sympathize with you a lot (owning a number of vintage lenses for several systems myself, though I have to admit I rather heretically mostly prefer the new-ish stuff!)

I guess, however, the collectors can just as validly suggest that they hate photographers who USE (and, hence, run the risk of scratching, chipping, breaking, whatever a classic lens which really, really belonged in a collection!) the lenses they'd rather collect...

Besides, if it wasn't for those pesky photographers ooohing and aaahing about how lens such-and-such was fantastic, prices would be oh-so-much-lower for those true lovers of vintage optics, the collectors... :)
After giving up an enforced routine schedule and allowing my sleep to settle where it will, I have found my sleeping "schedule" to be largely irregular.

Sometimes I want to stay up all night and keep going the next day. Other times, I go to bed at 9 and get up early the next morning. Sometimes I only need a couple of naps. Other times, I want to keep on sleeping, which I allow myself to do.

I have slept for 20 hours straight before, with only short breaks to pee and drink water. I think this typically happens when I contract a cold or flu, and helps my body focus on fighting it off.

I feel much, much better than when I used to have to be at the office every weekday, even if I could come in at noon.

I still have diffuse thinning hair in the area, so it feels like real stubble. Just feels less dense than on the sides, if you really measure your touch.

My wife knows from when we discussed it prior, but that's literally it. No one else has asked. It looks very natural as long as you buzz every couple days.

Be sure to get a natural hairline. Mine is receded in the temples rather than a straight line. Underneath my real buzzed hairline only; just filling in density.

In Sweden, I'd say it's mostly due to the immigration. The prevalence is much higher, unfortunately also strands that are harder to treat. It's not only stds, also other diseases such as hepatitis and tuberculosis etc, but it's not really addressed. No mandatory health checks, etc, that could help. Not totally sure why, it's a known fact and shouldn't be a touchy subject.
