I think the major physics problem that is very hard to fiddle, if you want to achieve the popular sci-fi version of VTOL flying cars aerodynamically, is the requirement that the cross sectional area of downthrust air fits roughly inside something approaching a car's plan view while still having room for occupants and luggage. Purely to hover such a thing, never mind ascend at a reasonable rate, requires airjets that will blow pedestrians cheerfully across a street.
This doesn’t apply to the dictators of North Korea or Turkmenistan, who are still doing their dictatoring the old fashioned way. Heck, the authoritarians of China are still stuck using methods from the 1960s and aren’t expected to modernize until after Xi.

Running a PSU at ~50% of its rated max is generally recommendable. At 115W * 2, plus other draws (disk, mobos, blinkenlights), that's around 300W.

Again: peak draw, when on.

I'm not arguing that this system is particularly efficient, only that you don't want to add 750W for the PSU to the draw.

I've not specced out low-power systems myself. I doubt you could get 40 hyperthreads running way below this, though there are definitely some low-power systems which might have a total budget below 50W. Reddit's HomeLabPorn may have some more useful guidance: https://old.reddit.com/r/HomeLabPorn/

(Not my area of expertise, I've never really stayed current in HW. Though I'm aware power/thermal budget has been a major focus, both mobile and server, for the past decade or so.)

My field is control systems. Every academic I know, and every paper I’ve read which mentions a software stack, uses matlab/simulink.
Simulink appears to me to have no good alternative (maybe jmodelica or something?) There are some python/Julia alternatives to matlab, but the existing control libraries are really pretty limited in comparison.

I’m not sure exactly how dependent particle physics is on ROOT, so direct comparison is difficult.
> You don't need a barrel shifter. You can shift one bit at a time. It's slower, but takes far fewer components.

I think I've finally found someone to ask this question.

How many transistors and space did it take to implement a 8-bit barrel shifter in the 1980s? I found the computing capabilities of 8-bit CPUs in retrocomputers, like the Z80 or 6809, were actually not too bad. With shift-and-add, a lot of computation can be done effectively, but their biggest limitation is the lack of a barrel shifter. Without one, no constant-time bitshift is possible with variable step, you have to shift 1-bit at a time. Performance could be boosted dramatically if a single 8-bit barrel shifter is included, and would open the avenue of a lot of optimization techniques for graphics as well.

Why didn't they include one? Especially when you consider that the Z80 was an "ultimate upgrade" of the Intel 8080, and the 6809 was the "ultimate upgrade" of the 6800.

Was it technical limitations, i.e. even a 8-bit barrel shifter is still too expensive for a 8-bit chip? Or was it that the cost of additional shift instructions decoding/processing is much higher than the barrel shifter itself? Or was it the lack of demand, i.e. it could be done reasonably well with acceptable cost, but simply no commercial reason in the 8-bit era to add one?
> All of the flying car concepts, which are like drones big enough to hold humans, promise to be better than helicopters. Helicopters are expensive to maintain, noisy to fly and require trained pilots.

They forgot to add helicopters can also auto-gyrate in the event of engine failure.

Quad-copter drones probably just crash.
It severely restricts the potential market if you do this (only travels from one skyscraper to another are supported). For instance you can just completely forget about Washington DC, London and Paris, and many more cities.

And even in cities with skyscrapers, they tend to be clustered in one or two districts, so you can only travel within a very small part of the city.

My feeling about the current push for flying cars and autonomous transport, is that when our grandchildren ask us about it, it will be in the same way as children today ask why they were still playing violins when the Titanic went down.
I'm lost as to how this will be effectively enforced. I've got a 2015 15" MBP that I use as a daily driver and after submitting the serial to apple shows

I don't understand why people are just shrugging off the adjective 'naturally'. Interest rates in the present system aren't natural, they are set by the central banks.

A system where a small number of central bankers choose a number might be a good system, but to call it natural is an abuse of language. If the 'natural' rate for lending money was 10%, we'd never be able to find it because the US, European and whichever other central banks would intervene.

They have a tendency to down-level a lot, which won't show up on levels.fyi (though if you look at the leveling by years of experience it might be extractable).

Also, from what I understand they tend to lowball much more aggressively than other top companies if you don't have any strong competing offers. Levels.fyi submitters will of course be the kinds of people who tend to shop around and get competing offers.
Laptop repair companies are disappearing for another reason, too... Brand new laptops are cheap. If your product is cheap to buy, it's harder to make money repairing the product.

Yes and no. The laws of physics do not pick out a preferred frame of reference, and they should be symmetrical under lorentz transformation, but the fact that we live in a cosmological universe starting with a big bang breaks that symmetry in practice.

It's similar to how the laws of physics are symmetrical under translation and rotation, but the presence of matter around us means the surface of the earth is not the same as the surface of the sun.

So, while we might use the CMB as a standard reference frame, the laws of physics should not.

Speed of light is not really just speed of light, but universal speed limit of causality. Light (electromagnetic waves just happens to be one of the few things capable of hitting that limit. Even the effect of gravity is limited to speed of light. PBS Space time has a good video on this - https://www.youtube.com/watch?v=msVuCEs8Ydo&t=5s.

So to answer your question, no it is not possible for anything to affect us any faster than the universal speed limit of causality (that light happens to be able to hit).
Uber's concept showed car ports up on buildings, so flying cars wouldn't be on the ground I guess. In that sense not very different to helicopters and dedicated heliports.
> It really feels like the modern world should be able to expose dictatorships and their propaganda machines much easier than in the past.

It is easier, but you might not have realised just how bad the situation was in the past. In the grand old days, propaganda machines were orders of magnitude harder to detect and challenge.

Consider how much we know about what is going on inside China in Xinjiang, Hong Kong, Tibet, etc, etc. Compare that to the old Soviet sytem where an academic could stand up on stage, say "This communism seems like a good idea" and be taken seriously.

I mean, even today, the American press on the left and right are both clearly running what are basically propaganda operations for the major parties. The easy availability of transcripts, raw recordings, etc, allow an interested denizen in a foreign country to peer behind the veil in a way that they couldn't 50 years ago.

>The unprecedented market rally highlights how volatile the Texas power market has become as coal-fired power plants, which have seen their profits squeezed by cheap natural gas and renewable energy resources, continue to close. Texas’s grid operator has been warning for months that plant retirements and increasing electricity demand has left it with slim supply margins.

>This week’s price spikes also underscore how dependent the region’s power grid has become on wind farms, which now make up about a quarter of the generation capacity in Texas. Lackluster breezes have contributed to the higher prices, Hehir said.

This is one of the downsides of the push to "green" energy. While wind and solar are great, there can be significant variability. Unfortunately, battery tech is not there yet to help with the supply-demand mismatches.

When I see people defend negative interest rates, I am reminded of this saying by Orwell: "One has to belong to the intelligentsia to believe things like that: no ordinary man could be such a fool."

>>One likely factor behind the savings glut and negative interest rates is negative “time preference.” Once upon a time, economic theory maintained that people always value today’s consumption more than tomorrow’s consumption – and thus display positive time preference.

An alternative theory: people's time preference is still very much positive, but becomes negative when presented with a set of equally bad options - negative interest rates plus high risk speculative investments plus a history of governments around the world unexpectedly seizing or devaluing wealth building assets. To me, these bad options seem to be the making of the governments and not naturally occurring scenarios.

You need much larger variable latency range to be truly annoying.

I'm talking high enough that someone backspacing over a mistake will think that the interface didn't receive the input. So they do another backspace.

To get it just right you'd probably trigger the initial backspace callback immediately after the user types a 2nd backspace. Then wait a long time before triggering the 2nd backspace callback. Since the original problem character has been removed the user will most likely try to continue typing. Finally, update the queue of characters all at once-- starting with the 2nd backspace. Now the latency has caused a character right before the queue to get eaten.

This is how you cause people to throw their device against a wall.

Why cant I comment on the other thread abt construction workers' suicides.. this is what I attempted to post:

---

>Why do so many construction workers kill themselves?

They got tired of building the future.

---

On . serious note, construction is a thankless, shitty job.

My dad was a general contractor, and he had an employee, who just had a baby... He took the baby to the neighbors house and asked them to "watch her for an hour" -- he then went back to his house and shot his wife, then killed himself.

murder/suicide....

I think that baby was like 3-months old.

---

Construction workers earn shit, are treated like shit and have REALLY physically demanding jobs. so their stress levels are HIGH.

I think that the idea of Universal Basic Income shouls aplly TO ONLY CERTAIN INDUSTRIES.

If you work in a certain field, which is a service field (basically) -- then yes you should get UBI - but if youre not contributing to society in any form - then no UBI for you.

Most of the 8-bit microprocessors I'm aware of -- including the Z80 and 6800 -- only had single-bit shift/rotate instructions, which didn't require a barrel shifter. Variable shift instructions were comparatively rare.

Besides, a 32-bit barrel shifter is considerably more complex than an 8-bit one. It's not just four times larger to deal with the wider operands; it also needs another two levels of muxes, making it closer to 6x as complex.

> The debtor is also "free" to default and not give you back anything. The interest rate is supposed to reflect that risk.

That is not the only thing interest rate is supposed to reflect. Interest rate is supposed to also reflect the price of transferring your consumption over time (if you borrow , you want to consume earlier, if you lend, you want to consume later). And there is no real [1] reason why this price would have to clear only at positive values. So you have also possibly negative components on affecting the interest rate, thus it is completely feasible that the total interest rate is negative.

[1] outside the flawed assumptions of economics textbooks, that is.
