There's still some interesting stuff showing up on Show HN threads though.
It seems to me that it’s a question of long term energy needs, i.e. when civilization goes to the next level and wants to send laser-propelled light-sail equipped probes to other planets with 10% speed of light.
As I understand it renewables and batteries have their own environmental impacts that can't be ignored. When comparing nuclear with renewables the impacts start to show nuclear as at least a good contender as the future power source. But large scale fusion might drastically lower energy costs. That could enable things like carbon capture.
It's the corporations, and big Pharma, and the Pentaverate.
Methanization is currently expected to be the critical storage component for CO2 neutral energy systems. A major driver of storage need in many places is not renewable fluctuations but seasonal fluctuations: You need more heating in winter/AC in summer. So make Methane and store the gas. Technologically this is all solved.
Thanks for your response! Last question...

Will the clustering target just replication (HA) or will it also target sharding for scaling out storage capacity?
When ATT was a monopoly, your choice for a phone provider, across the U.S, was ATT. There was no way to switch, and they used this power to raise prices (hurting the consumer is generally a requirement for anti-trust cases in the US).

It'll be very challenging to win a serious court case where the Google search monopoly could be conquered by a user typing bing.com at the top of the screen. Never before has a 'monopoly' been so easy to stop using.

>people need food and shelter, some electricity for electronics and some transportation

Modern shelter, food and transportation means a lot of energy.

Modern shelter means operating energy for heating or air conditioning, plus embedded energy used to create its components. If the shelter is green, or "energy efficient", it means it is operating energy efficient, but it contains a huge amount of embedded energy in the insulation and heat exchange components.

Air conditioning doesn't necessarily have a worse bottom line, energy wise, than just heating. It's all about the time * temperature difference envelope. Air conditioning usually has a much lower temperature difference between the outside and the inside. If it's 40 C (as hot as it gets in places where masses of people live) outside, air conditioning has to drop by 15 C to get the inside to 25. If it's freezing (0 C) outside, heating has to heat by 25 C.

Double that for a modern workplace - office, warehouse or manufacturing, they all consume a lot of energy to keep the workers comfortable.

Modern high-speed transportation means a lot of energy too. We move crash-resistant 1500 kg structures at highway speeds around daily.
This is an odd jump you are making. Most energy isn't used just for food, shelter and some transportation, and certainly not for "bitcoin and simulations".

By far most energy is used to produce things (including the transportation requirements to do so). And as it turns out, the hunger for producing and buying new things is very hard to temper. This hunger is evident from the fact that the ways we are measuring "economic success" strongly correlates with the amount of things we produce, or even with the speed at which we are increasing the amount of things we produce.
Congratulations on your journey.

Sure, just sharing observations.

The schools for example had officers with submachine guns when it was time to let out, and giant vehicle barricades. I suppose this could be to scare people. But that's what's there.
I don't buy this.

We are wasting massive amounts of energy.

20 lanes of stop-and-go SUV's all single driver traveling over an hour to jobs that they hate. Terrajules of energy to create a single piece of electronics designed to break in less than 2 years. Massive manufacturing of throw away disposable items. The list goes on.

Ah, but the simple matter of fiddling with the sign has ramifications. You end up with people having to cram mnemonics into their heads like DEAD CLIC, and PEARL. On top of that, there are awkward limitations like a transaction having to work with exactly two accounts, one of which is debited and one of which is credited. The actual numeric deltas applied to the two accounts by the debit/credit can be any of the four combinations: UP/UP, DOWN/DOWN, UP/DOWN, DOWN/UP.

Under the sum-to-zero system, it's very simple. Negative-running accounts is what the system owes to the outside, including to its owners. Positive accounts are what it holds. It doesn't own anything: all of what it holds is either owed to its owners, or else to other creditors, so the sum is zero.

A transaction can update two or more accounts. The only rule is that all the deltas in the transaction add to zero.

That's as far as keeping balance is concerned: of course, the transaction has to reflect reality and accounting principles. For instance, if $1000 is injected into the business somehow (the company wins a lottery draw), that could be mistakenly applied as "+1000 cash, -1000 bank loan" which validates, due to summing to zero. But it looks like the company made a $1000 draft against the bank loan, which doesn't reflect what happened. The correct transaction is "+1000 cash, -1000 equity": the company is $1000 richer and so the owners have a greater interest: it "owes" more to the owners. (It's sort of as if the owners actually got the money, and loaned it to the business).

The debit/credit system's rule that a transaction must have a credit and debit of equal size also do not prevent bad transaction semantics: transaction from using the wrong asset or liability/equity account. It's just a gratuitous complication which provides exactly the same sanity check as summing to zero.

In my accounting system for self-employment, I have transactions that update four or five accounts. In double-entry, that would have to be done via an awkward series of binary debit/credit pairs. Moreover, I also have some "virtual" accounts: pairs of accounts that maintain precisely opposite balances that sum to zero. These accounts provide figures useful for reporting. For instance, suppose that transactions for receiving income are broken down: income doesn't go into a single lumped account, but some of it into "cash", some of it into "income tax withholding", and some into a third account like "health fund". But, for the sake of periodic income reporting, we need the whole lump together. For that, we can instantiate a virtual account pair "income" and "income-neg". In the same transaction, "income" receives the total, and "income-neg" the additive inverse of that to keep the ledger balanced. We can query the "income" account to see the lumped income, and not have to ferret that out of the income transactions.
I would argue that we are already seriously building more and more solar and wind power, along with research into better battery storage. Even if we solve the current climate crisis with solar and wind, we may still be able to do even better with fusion in 50 years. Fusion would be very energy dense, requiring a lot less resources and land than solar or wind, and has the potential for even cheaper and less environmentally-destructive energy than current renewable resources.
Yes that has a big impact. The quality of a tokamak (as meassured by the triple product density, temperature, and confinement time) goes up like B^3 (IF I remember correctly, I do plasma physics but not fusion stuff) and the fussion power goes up like B^4 or something like that. So larger magnetic fields help a lot. But back when ITER was designed we did not have such strong superconductors yet.

The article mentions the first class the author took taught them Sudarshan Kriya, which is a particular kriya that the Art of Living Foundation teaches. From what I understand a large part of the kriya involves bhastrika pranayama, which is pretty much what the beginning Wim Hof method is, except he adds a kumbhaka (breath retention/hold) at the end of the 30 breath cycle. I appreciate what Wim Hof is doing, but a lot of these techniques have quite a long history in yoga.

BEGIN ME FUCK AGAIN
Yeah, I'm mildly confused by what the sell point here is. I sort of assume that any loading of remote resources automatically represents tracking information for this use-case, every email can be trivially individualized to the receiver and in turn I don't see how it's feasible to prevent resource tracking. You either load remote resources, or you don't. I guess if techniques remain relatively unsophisticated for email and few people bother then individuals might slip under the radar, though partial blocking itself represents a signal. But unlike the web individual messaging remote resources seems like an arms race users would be destined to lose.

The only thing I could see really working would depending on a really big service that processed every received email immediately and proxied all remote resources without any user interaction. Plenty of challenges there too though, and harder to make it work with regular clients. Maybe dynamically rewriting the email to point to the proxied resources? Or automatically rendering/inlining them?

Which fossil fuels are "less bad" for the climate? They're all very bad.

Obviously old coal powerplants are the worst, but there's more evidence every year that the allegedly "clean" natural gas is nowhere as clean as advertised once you account for fugitive methane emissions that in practice are largely untracked. And flooding the market with cheap fossil fuel like methane as a "transition fuel" – another marketing gimmick – will only delay the transition to renewables for obvious economic reasons.

I'm not optimistic about big shots like fusion, but small modular nuclear reactors for example could be operating relatively soon if only we had the desire to go in that direction.
Mario Paint [video]
The fundamental difference between nuclear and any other source is energy density. It boggles ones mind that your can replace burning 14 thousand tonns of coal _every day_ with something that needs to be refueled once a year.

Do you have a source for this? I was also under the impression that fusion has never yet produced a net of energy.

However, I did sometimes generate the response multiple times, especially if the first response didn’t make sense, or if I just didn’t like it. In some cases I used its first response, but often I had it generate its response 2 or 3 times before I was satisfied, and on rare occasions I had it generate a response 6 or 7 times before I got one I was satisfied with.

I would be really interested in a version of this with just the first answer the model gave.
A two beam setup would allow differentiation between entering and exiting of single clients. Then the question comes down to how often do 2+ people cross the beams at once, and does that have enough of an effect on the aggregate statistics, if it was taken into account (e.g. count each crossing as 1.1 people, if 10% of beam crossings are 2 people)?
> Believed to have medicinal properties, garum was used as a disinfectant, eye and ear cleanser, to treat burns and dog bites, and to fight high cholesterol.

Wait, the ancient Romans somehow knew about cholesterol? Um.
>This is just not true, there's no way you can say this. Solar costs are going down massively. Hydro is dirt cheap already. So renewables can absolutely be part of an energetic transition in the near future, while fusion is at best many decades away. So while I think fusion energy has the potential to transform energy generation, and by extent everything about our life, it's wrong to assume renewables aren't probably our safest bet in the near future.

We need nuclear to meet baseload because the storage requirements (for PV particularly, by far the largest renewable) would be absurd without it. But since peak load can be several times average and nuclear plants can't be spun up in a day, we also need storage, and with storage around renewables can be cheaper than nuclear. It's not an either-or question; both should be used.

Climate agreements have largely avoided the thorny question of providing nuclear power to the developing world, but if they're to achieve a prosperous standard of living in a sustainable future based on foreseeable technology, this has to be addressed.

Yes, I've seen this as well and from my observation, it seems to boil down to company culture and a lack of product direction. A company that refuses to accept that errors and faults happen tends to permeate into the code. A lot of people that work on the product side will say "I want us to have no failures" without understanding that things simply WILL fail at times and we need to understand what the user experience should be if this were to happen. This is especially true of external services that you have no control over (i.e. the usage of a push notification system).
They don't seem any different from other industries in this respect. A lot of banks still run on systems originally designed in the 60s. So they are conservative from an operations perspective. But most of the big ones have no issues pumping money into the latest financial fad, so they are pretty flexible from a product perspective.

Their content is relatively cheap to produce and it tends to be churned out at a high frequency. There's almost no industry out there that matches the frequency of content they produce, except maybe radio (and now YouTube). And with new technology, the limiting factor is almost always content creation.

So it makes sense that they'd put aside a few dollars buy some new equipment for some trend. Doing a VR shoot probably involves a new camera and a plugin for Premiere.
I do sometimes get anxious. Quitting caffeine and doing 10-20 minutes meditation everyday has helped my anxiety. Meditation has had a cumulative effect on my mental well-being. That is, the more time I spent meditating, the better I became at it and feel more at peace when compared to when I just started. Meditation also helped my sleep schedule which I believe helped with anxiety in turn. N=1 but may be it helps you too.

People on feminizing HRT.
Thanks for pointing out, because now that I think of it, my view does come off as odd. What I think it reflects is that despite nuclear fusion being a technical, engineering problem, I believe getting companies/governments to abandon carbon for wind/solar to the point of carbon-neutral is even more insurmountable. Does that viewpoint make sense? For them to get off fossil fuels, it's going to need a ball-out-of-the-park solution. It's too hard to compete with the fracking revolution.

It's not really even that much of a problem, long term, and it might help out certain sectors of the U.S. economy, given that we produce a fair amount of our own raw materials so that we don't suffer as much from a weaker currency in buying raw inputs. It would make our exports more price competitive.

HOWEVER, the effects of a rapid, uncontrolled fall would be quite disruptive, and a lot of people who had their savings in $$ would now have no savings, and that could be very bad, especially since most of those with their savings in currency would be small time investors, retirees, etc. who cannot afford an advisor to help them diversify.

It should be mentioned that many nations have, at various times in the past, intentionally devalued their own currencies. We have at various times in the past accused Japan, China, Germany, etc. of intentionally preventing their currency from appreciating. But, major swings in short periods of time can be painful.

Because of the things cited in the article I spend less time in the Google search results page. I typically find the answer I'm looking for and get on with my day. Because I'm spending less time I actually use it more now.

Sometimes when I'm looking up stuff on how to do things physically like how to install a part in a car or fix something in my house I'll get a YouTube widget at the top which will take me to the exact moment in a video where what I'm looking for is being performed. This is magic to me. However Google is definitely promoting themselves in this case and I might not go anywhere past the very top of the search results page. Is this a bad thing?
