No, pumped storage is not feasible. It's both geographically limited, and it's not available at the appropriate scale. Estimates for how much storage would be necessary for renewables to work range from 12 hours to weeks of storage depending on the solar and wind mix. The US has ~25GWh of hydroelectric storage. There are no active hydroelectric storage projects at the moment, only proposals [1]. This is why proposals to decarbonize through intermittent sources always assume a nearly-free mechanism of energy storage.

It's easy to make renewables look cheap if you assume some wundertech makes storage free. Will thermal storage, synthetic methane, or who knows what else fulfill this need? Who knows, but they don't yet. Thus renewables only present a solution coupled with an engineering breakthrough. It's like assuming moore's law held true and developed an app that assumed it'd run on a 1THz single-core processor presumably developed a decade in the future. Seems reasonable in 1995, but that's have been a very bad bet.

I've often wondered if the speed of light was somehow related to the computation cycles per second of our universe.

For example, imagine if the universe was made of a three dimensional fabric of tiny pixels, and the only way information could move to another adjacent pixel was one universe calculation at a time.

So when something without mass is moving across a field of pixels, its speed is capped by the number of universe calculations happening per second.

The temperature of the material is the same on the top and bottom (less than 0.1K difference they say). The mechanism is rather that the air molecules are entrapped in the nanotube coated under surface and heat up more, so depart with a higher velocity than the upper surface. This creates lift.

Quite a cool effect, reminiscent of an army of Laplace's demons kicking air molecules off the bottom of the surface to make it fly.

something interesting from biology that no one is aware of...

plants that do photosynthesis can be stacked if they are different enough to grab different parts of the visual spectrum...it happens in oceans and tropics etc.

metal only get's electron excited in the uv light range and thus cannot be stacked.

Vertical farms do not stack those plants that grab different areas of visible spectrum as plants generally are dominant in one visible spectrum area more than the other one..red vs blue vs green

whereas algae specialize by the visible spectrum they grab for photosynthesis ie red, blue, and green algae...color reflected form them is not the color they use to photosynthesis ie red algae do not use red but a different color to photosynthesis

We are doing it wrong

we should build a bio-battery film of different algae and stack them to generate electricity from the sun instead of metal solar panels. Even transparency and other improvements only gets solar to 45% effectiveness...with algae we could get much higher
If you can't see the practical utility of cryptocurrency in 2021, you're being willfully ignorant.

If you actually believe what you're saying, then short it[1]. If you really think that the practical value is non-existent, then put your money where your mouth is, and take out a short.

This isn't some academic theory where the best you can do is throw tomatoes at it, and ridicule it from a distance. This is an economic theory, where if you are correct, and everyone else is wrong, you can profit significantly from it.

Maybe once you're faced with actually taking a stand on a belief like this, you'll come to understand why cryptocurrencies are beginning to dominate the global economy. It's also totally possible that you're right, but I think it's far more likely that you just like to ridicule things you don't understand because you get some sense of power from shitting on people who you consider to be beneath you.

How exactly do you "censor" something information that is part of the public record? It's part of the public record.

Nobody is saying they aren't allowed to publish the information. Tabloids exist and can say whatever they want, but a serious outlet like Ars is held to higher standards by their customers. I assume Ars removed the names because they agreed those details were unnecessary and only served as a potential liability for those named.

Free speech means the freedom to say or not say what you want. Ars chose to not say something of their own volition.
Mining operations are obviously quite secretive about any edge they have againstb their competitors but its not much of a stretch when there are stories like this one:

The trouble with your reasoning here is the idea you can protect people from themselves. The second problem is that heart disease is the biggest killer, and there's no rational way to use the law to stop that.

Extreme sports, fast cars, alcohol, boxing, hell, even gymnastics, unprotected sex.. you see where I'm going with this.

What's moral is a separate question of, what's the best policy for society to keep people as safe as possible. Bootleg cigarettes and fines (prison?) are probably not those things.

Besides, some people can smoke moderately or rarely and not get addicted or die.

Finally, you're too soft on your alcohol prohibition stance, where you're saying you can see the benefits. Empirically, do you see the benefits in the creation of a criminal syndicate that still exists, a century later? History has spoken, prohibition causes harm.

> These companies are profitable, but only because the process relies on a supply of cheap fossil fuels. If solar panels supplied the energy, the extra costs and space for the energy supply would again cancel out the savings in terms of space and costs.

Given that solar has become so cheap that new solar is able to compete with existing fossil fuel power this conclusion seems outdated. Solar can be placed in many places where it's not possible to plant in to the ground and it also doesn't account for power from other renewable energy sources that aren't available to plants in a field ie. Wind and Hydro
I agree, but it should be noted that this isn't unusual for Nvidia: See Quadro Vs. Geforce. If you trick a system into thinking the Geforce GPU is a Quadro suddenly additional functionality/performance improvements unlock in the software/driver layer.

One of the biggest challenges with online drug discourse is that discussing negative side effects is not welcomed. The discussion is too entangled with legalization, leading to a lot of defensive responses trying to dismiss or downplay risks.

Discussions of legalization aside, I agree that psychedelics aren't as as harmless as internet discourse suggests. There is a massive difference between someone being given psychedelics in the presence of a trained therapist once or twice in their life and someone taking LSD hundreds of times alone in a recreational manner. We have to be honest that excessive psychedelic use comes with significant risks that aren't always apparent to the users.

My uncle just finished serving his jail time and has entered a world of shorter working hours due to regulations. Hard to solve for unintended consequences. Will likely be homeless soon.
You’re confused.

They claim they are going to fork ETH to make a POS fork of it. Now the people claiming this are going to want you to believe that’s the “real” eth- but the miners may not agree. They have no incentive to do so.

And yes, they can absolutely keep running the real chain and let the chips fall where they may. Given that course of action benefits them, and the other benefits Vitalik and his whale friends...
you should try to avoid zero sum thinking, it only leads bad things and is almost always incorrect.
I think a better way to do it would be to basically cut the crap and target companies based on what they're obviously up to.

If a company has more than say X% of their workforce part-time (say between 10-30 hours/week, with <10 hour employees ignored in the denominator) for a period of Y years, every part-time worker gets full benefits, unless they are working another part-time job in a similar company, in which case they get benefits from one and the other will add their average employer contribution to their salary (this reduces uncertainty). Or, if they are working a full-time job (this is unlikely, except for a few businesses e.g. bars) or attending a university that offers healthcare, the requirement can be waived or some appropriate counterbalance can be devised.

The relaxation of labor laws for part-time work is intended to allow employers to efficiently deal with acute labor shortages, not maintain a firm of intentionally precarious and uninsured employees. An exception can be made for businesses which operate less than 30 hours per week, since they have no choice.

Granted, more systemic reforms would be nice, but this problem can be dealt with directly and harshly because it simply shouldn't happen.

Why do you care so much about predictable supply if the price is anything but predictable? How is such high volatility commodity a good storage of value? It might be a good speculation vehicle, but people looking to store value typically look for something more stable.

> All this criticism also applies to vertical farms where lettuce and tomatoes are grown. In this case, there is a significant reduction in water use. These companies are profitable, but only because the process relies on a supply of cheap fossil fuels. If solar panels supplied the energy, the extra costs and space for the energy supply would again cancel out the savings in terms of space and costs. The only advantage of a vertical farm would then be the shorter transport distances. Still, we could just as well make transport between town and countryside more sustainable.

This may be true, but I'm having trouble reconciling it with the notion I've read elsewhere that solar farms are producing some of the cheapest energy prices per KW/h. (Though maybe once you factor in energy storage it comes out more expensive than natural gas or coal?) Anyways, if these companies are currently profitable at current energy prices, that seems to imply that being profitable on 100% renewable energy isn't that much of a stretch.

(Though the criticism that lettuce and tomatoes aren't a good source of calories/fat/protein and aren't enough to feed a population, if that was your goal, remains valid.)
Oh wow, that actually sounds much nicer! I wonder if it's worth switching to this or if I may as well stay with ohmyzsh for now and switch to zsh4humans in future installs.
A lot of people here are criticizing the methodology. That's fair, I don't know enough to weigh in.

But what I can say for sure is that in real-world use, on Mac, Safari absolutely feels lighter weight than other browsers. The fans spin up less, the battery lasts 30% longer, and other apps seem to be more responsive. I don't know if that's memory or cpu or what have you, but it's real.

You do pay a price in actual page-load times. Chrome absolutely has a small but noticeable edge in raw browsing speed.

I suspect this comes largely from Safari's tight integration with the rest of macOS. I recently had occasion to read a bit of Chromium's Cocoa UI code (to help the developer of https://github.com/blueboxd/chromium-legacy track down some bugs), and my very surface-level interpretation of what I saw could be summed up as "how can we get rid of macOS's native functionality and use our cross-platform stuff instead?"
This is also the reason that having the latest drivers are important for the best performance and stability in new games.
Both my wife and I graduated GT ChE 35 years ago and really liked living in downtown Atlanta. Not many traffic problems downtown, midtown, out east except Ponce at 5PM. Afterwards PHX, Mountain View, Santa Clara, and a delicious stint in '90s SOMA. Now 25 years in the mountains of AZ, lots of experience with PHX traffic. I just got back from 2 days crisscrossing PHX at 80mph, 9AM-3PM.

I've driven in many US cities, and had to suffer the DC traffic horror show for work trips.

My wife's current company HQ is across the mighty traffic river of the 285 from the Brave's fancy new ballpark.

I used to tag along on the twice yearly trips because in theory, downtown and midtown Atlanta are pretty good looking and have a lot of cool urban things; then there are the Buford HW culinary expeditions.

I stopped because even though I had complete freedom to travel in the middle of the day, using Google Maps for advice, I could not get even a single day when one direction did not fail into stupid dumb no way to route around time destruction gridlock.

I watched the Guadalara MX evening commute for 5 days from something like 25th floor of the hotel, and it made me think. A couple of trips to the 'De Efe' MX and stupidly riding a tourist bus at 5pm (no time to spare!) made me think some more. Yesterday I was looking and thinking about Tempe, and its absolutely magnificent building boom. It's a spectacular transformation, for an American City. La Defense, without decent art. I wouldn't want to spend much time in either... Tempe because of the soon to be 130F summer days. LD, because if you're in Paris, why??.

Both Tempe and Atlanta have built a beautiful urban infrastructure with tall business and residential buildings that are generally structured as 3-7 stories of vehicle storage, possibly underground, and a bunch of greatness stacked above.

Tempe is headed toward the worst commutes south of the border, and Atlanta is already there.

Yeah, I haven't mentioned something here. Deh Efe has it and it doesn't matter. Tempe at least has that freight track it will eventually commandeer. Because of city fragmentation, and some uh residual social issues, Atlanta is a lost cause. The future is very, very stupid.

I'm not a transit expert, but I do love to ride the trains.
Since we're firmly in the ridiculous arguments camp already, it may as well be pointed out that all of that energy leaving the planet is a good thing. It's why the earth isn't a barren hellscape like venus, whose atmosphere captures energy much more efficiently. Most people would actually prefer that we capture just a bit less than we currently do.
> Many commenters are missing that the issue is not that an Open Source project was repackaged as a commercial project, but that the open source origin has been hidden.

That is not what Joost VandeVondele, current maintainer of the Stockfish project, posts:

> Recently, ChessBase has started distribution and sales of the Fat Fritz 2 chess engine. This chess engine is a Stockfish derivative, with a few lines of code modification (engine name, authors list and a few parameters), and a new set of NNUE net weights considered proprietary

> Selling Stockfish derivatives is possible with the GPLv3 license we grant, but not without requirements. In particular, the license states that if one redistributes a program derived from our work, the corresponding modifications of our sources and all information needed to build that program must be made available. Only after explicitly informing Albert Silver (the author of the net in Fat Fritz 2) of a license violation have matching C++ sources, but not the net weights, been made available. Obviously, we condemn the approach taken.

There are two incentives for miners: the block reward and the transaction fees. After the max number of Bitcoins is reached there will be no more block rewards but fees will continue.
OK, but the situation still looks shameful. What exactly prohibits a web site from consuming all my RAM? I have never once seen a browser make a misbehaving site wait (frozen with no CPU) for me to confirm that sucking up more RAM is acceptable to me.

What happens instead is that I hit a wall of slowness, forcing me to press the power button and lose all my other work. It's not very gradual, I think due to the nature of the problem, so the browser needs to avoid getting into the situation. It's like UI latency follows a hyperbolic curve, running right up to infinity all of a sudden as the RAM runs out.
Fantastic, downloading the latest version now!
I'm sure that (read: I'm very hopeful that) that will change once pandemic restrictions lift because there will be a surge of demand for live music, public entertainment, and so on -- a pretty extreme sort of rubber band effect.
It’s baffling. Almost like people do like both to complain and to not have nice things. I bet that a huge part of them don’t do neither of ML, mining, nor free software at all. The naked fact that a mid-tier card already costs half a decent car escapes their reasoning somehow.
Yeah and it’s actually decent.

That being said I don’t mind committing often. If I have a slew of small commits I squash them.

Since I will need to commit at some point, I rather do it incrementally.
the vast majority of mining happens off renewable energy, because it doesn't make economic sense to mine on non-renewables. its why 'mines' cluster near hydro plants and places that have good solar.
This inspired me to grep the cpython code for sprintf.

I found one used with the return value from alloca (inside FindAddress in _ctypes.c). It checks alloca for NULL (does alloca ever return NULL?), but I could imagine it might expoitable. FindAddress is a static function that can be called during DLL loading. I imagine that there is very little code that accepts untrusted arguments to DLL loading though (if so, there are bigger problems...).

There is also a lot of use of fixed 32-byte buffers, for up-to-64 bit numbers, which is fine, but hopefully if in the future they can be 128-bit, people remember to fix it!

In other cases, like getnameinfo, the stack-allocated buffer is way too large! %d can never be 512 bytes, so it's just thrashing your cache for no reason.

Anyway surely this has been carefully audited, since grepping for sprintf is so simple!
You are correct that he held that position under Trump and bears responsibility for problems with federal regulations.

However, his strict anti-federal stance goes back many years. He did not adopt it or even emphasize it to make excuses for this situation. He's just like that.
States like Minnesota and other northern states have had much more extreme cold temperatures than any of these Southern states--yet they haven't had this blackout problem. Why not? Because they seriously winterize their systems.
If you're defining a couple houses as having power, sure. If you're talking about recovering the entire customer base? Not a chance. Power Distribution grids have been running on margin for years, if not lowering capacity. Clearly you have no idea what you're talking about but you still need to post. I don't understand why. Care to share why?
Maybe I'm just a blind leftie, but I think one side got called out for attacking the capital because that's what they did. And the other side had thousands of protests, 90+% of which were completely peaceful. Granted, it's a small sample size of on the insurrection side, but 100% violent, versus < 10% violent.
Yes this could save a lot of arable or environmentally significant land, even if it didn't save a net m^2

It's not pure profit because, a) you can only oversubscribe 20GB/s so much without data caps and speed limits b) a small fraction of the constellation will be over inhabited land and wealthy enough countries at any moment c) I am assuming they lose money the first ~1.5 years to recoup the dish cost and R&D, d) ground link opex e) sats fall out of the sky and need replacing f) subsidized launches via rideshare only work if there is enough demand into inclined LEO, otherwise its $30M per launch at per sat costs go way up g) Customers are not uniformly distributed over earth's landmasses
comparable seems like an implicit part of the question? Cold weather caused problems in all states; Somebody surely slipped and fell down somewhere. That doesn't give information on whether their grids are better at handling weather changes though
