Not sure where being a "customer" or not comes into it. You sign quite a bit of contractual agreement when entering a university, that takes precedence over whether or not you give them money. Either it's enforceable according to that or it's not but you don't get to retroactively red-line things just because you were the one paying for the service.

Of course "refusal" could simply mean you will go elsewhere, whether you get your money back is up to the agreements you signed when you gave the money though (you won't, at least not all of it).

are you referring to specific groups involved with the Tesla gigafactory?
What evidence is there that it is a serious problem?
Environmental activists and other groups opposed to major construction projects in Germany have a tendency to latch on to even the most minor potential issue and complain and sue. The strategy, as far as I can infer it, is to delay the project and drive costs in the hope that it will have to be abandoned. It rarely works, but in combination with long and arduous processes for building permits, major construction projects can be held up in the planning phase for 10 to 20 years these days.

The Tesla factory is a huge exception, mostly because Tesla went ahead using temporary permits and took the risk that the final permits may be denied. The project has a lot of political support, which also helped the process along.
you also have a single point of failure, which is a double-edged sword.

Interestingly enough I was given this problem (well, numerically stable online variance, but close enough) a while ago as a take-home job interview and I ended up researching this quite a bit.

It has been a while, but if I remember correctly pairwise sum was in practice as good or better as Kahan summation (and both more stable than Walford's) but faster.

But by far the fastest and still very stable solution was to use the legacy 80 bit x87 fpu as accumulator. Which is not surprising as Kahan explicitly added 80 bit precision to x87 for intermediate computations.

That would actually create an equal playing field, given how easy German companies get finned in the USA.

This just shows how big protectionisms is that domestic companies enjoys in every country. We all talk about free competition, but somehow Monsanto needs to pay huge fines in the USA as soon as it became a German company, while VW enjoys full protection in Germany and Europe, while being heavily punished in the USA.
The average C++ codebase isn't from the 90s. On all the recent c++ polls the average language revision used is between c++14 and 17.

Besides I'm pretty confident that there are more new c++ projects created daily in 2021 than monthly at the peak of the 90s c++ craze - just on GitHub, 6/7% of C++ repos means a few million recent C++ repos.

It becomes unbearable not because of heat capacity but because of inability of the body to expel heat.

When outside temperature is equal or higher than body temperature the only way to expel heat is through sweating. For this the air must by dry enough (wet bulb temperature less than body temperature). https://en.wikipedia.org/wiki/Wet-bulb_temperature

If body can't expel enough heat it results in eventual death.

We are not the ones reading these petitions, so it’s arguably irrelevant what we think about them. I suspect many environmental groups do limit themselves to reasonable exceptions, but when any group can do something some will object to everything.

As such it’s not about environmental groups doing this but rather specific groups.
This is absolutely spot on, great interpretation.
Please remember to assume good faith by taking a charitable interpretation of people's words.

For example, we can see reference to the broader issue of gender bias rather than so narrowly focus on a specific claim about elementary teachers. To that point, there is substantive and substantial evidence of gender bias in STEM:

Yes, for the record, I believed then (and still believe today) that the virus has zoonotic origins. The primary point of evidence that the lab-leak advocates point to, the fact that the animal reservoir hasn't yet been identified, isn't convincing to me. It took more than a decade to find the animal reservoir for SARS. We still don't know where the animal reservoir is for Ebola.

Similarly, the presence of the "furin cleavage site", which supposedly makes the virus ideal for spreading in humans is less significant than it appears. There are numerous other coronaviruses which have the same feature, and it's plausible that SARS-COV-2 picked up the feature via recombination somewhere on its way to becoming a virus that spread primarily among humans.

But all that is beside the point. The point is that many voices that took on the air of authority during the pandemic changed their view for no reason other than shifts in the broader political climate. It has made people suspicious and frustrated with the experts, which then leads them to embrace crackpot theories peddled by those who (correctly) point out that the authoritative sources in the media have been lying to them.

The solution, as I see it, isn't that the media should get its facts and story right the first time. That's impossible, especially in a fast-changing situation like the early stages of a global pandemic. What the media (and by "the media", I mean major newspapers like the New York Times, and major news outlets, like CNN) ought to be doing is stating clearly when one of their stories contradicts a story that they've published in the past, and stating clearly the reason for the contradiction. "We were wrong about masks, because we misinterpreted a directive to preserve masks for emergency workers as meaning that masks were ineffective," would have gone a long way towards helping convince mask skeptics about the need for masks when the media suddenly reversed its advice.

That bit at the end about Gresham's law made me cringe. This guy doesn't have any business talking about money publicly unless it's asking questions and taking notes.
Also, Hyrums law are about unforeseen breakage because people did not relay only on the documented API specification. This is undesirable, and in fact hard to avoid completely.

But most breaking changes such as in semantic versioning major number changes do intentionally break client code, which is an entirely different thing. There are a few rules one can follow which make it pretty improbable that such foreseeable breakage will happen. And this will constitute more than 99.9% of API breakage - even more if you stipulate that undocumented features must not be relied upon, and client developers follow that rule. Developers relying on undocumented behavior is usually due to a lack of clear documentation, so it is largely avoidable, too.

I’m surprised no one has mentioned sleep restriction.

About six months ago I herniated a disc pretty severely in my lower back. Initially totally messed up my sleep with real pain…then the pain turned to annoyance and just caused me to wake up frequently and have a tough time ignoring and going to bed. And eventually the pain went away all together…but what was left was a major sleep problem. Couldn’t go to sleep, couldn’t stay asleep. And I have been a perfect sleep through the night sleeper my whole life. Was super rough.

Benzos didn’t really help. But what did was sleep restriction. I must have totally obliterated my circadian rather over months of dealing with the back pain.

So I set hard 6 hour sleep time every night. In bed at 1:30am. Out of bed 7am. Even if you don’t sleep a wink. Up same time. Then immediately go outside and stand in the bright sun. Spend zero time in the bedroom other than to go to bed. Rinse repeat. First couple days were brutal…but then it started to come back. I was tired again at night. My body was begging to sleep. And getting up in the morning got hard. And after two weeks…added 15 min. Earlier bed time. Two more weeks…15 more minutes. Two months later and im totally back to normal.
The article explicitly says while you might get away with it with some luck due to characteristics of the real world data, you do have to be careful.

From TFA:

"Now, in the real world, you have programs that ingest untold amounts of data. They sum numbers, divide them, multiply them, do unspeakable things to them in the name of “big data”. Very few of the people who consider themselves C++ wizards, or F# philosophers, or C# ninjas actually know that one needs to pay attention to how you torture the data. Otherwise, by the time you add, divide, multiply, subtract, and raise to the nth power you might be reporting mush and not data.

One saving grace of the real world is the fact that a given variable is unlikely to contain values with such an extreme range. On the other hand, in the real world, one hardly ever works with just a single variable, and one can hardly every verify the results of individual summations independently.

Anyway, the point of this post was not to make a grand statement, but to illustrate with a simple example that when using floating point, the way numbers are added up, and divided, matters."

you're gonna need a reference for that statement champ, cause that frankly doesn't pass the smell test.
I've spent 10 years writing security critical C code. There's no problem writing secure code in C. You just have to stop being clever and prioritize security above "speed". Your code will probably be fast enough anyway.

If it's too slow, then you probably have an issue with which algorithm/data structure you chose and would have had the same issue in another language.

The biggest issue I have with C today is that you can't trust that your compiler actually generates code that is 1:1 with what you wrote. I'm not talking about UB here, your compiler can actually remove code/checks even though you don't invoke UB.

Then we have UB, I think UB should be removed from the spec completely. There probably was a point in time when leaving stuff as UB was the best option, but today speed is seldom the problem, correctness is.

I no longer work as a C programmer, but I still love the language and I really enjoy writing C code, but I really would like to get rid of UB and have a compiler I can trust to generate code even when I turn on optimizations, and having optimizations off is not an option either, since it can generate broken code as well, so...

Is that illegal?

Yes. The 2012 STOCK Act prohibits it.
Multiparty system has failure mode, when one party balloons in size, either by aggressive use of populist rhetoric (NSDAP) or by merging several smaller parties (United Russia). At this point rest either have to unite (producing two party system), or become irrelevant (producing single party system, opening way to totalitarian or authoritarian regime).
Tell them you're home and you're using one of those custom backgrounds.
Here's what's going on here: banks use debt to increase their returns. A bank might have $100M in capital, $1B in assets, and $900M in debt. Now, to keep things from getting too crazy, there are national and international regulations limiting how much they can borrow. Those limits depend on how risky the assets are that they're buying. US government bonds? You might need to have 3 cents in capital for every dollar of T Bonds. For high quality commercial bonds, maybe 5 or 10 cents.

Cryptocurrency is a new asset class, so they have to decide how much capital a bank needs to hold. Quite sensibly, given its volatility, you need $1 in capital to hold $1 in crypto. I.e. a bank cannot borrow against its crypto holdings.

You can make a rough estimate of e.g. the CO2 emissions due to youtube and bitcoin, and thus get an idea of how the two relate.

E.g. a quick google finds this: https://www.nature.com/articles/s41467-021-22256-3 or this https://www.bbc.com/news/technology-56012952 - so let's say bitcoin uses 150 TWh in 2021. Here's another one: https://digiconomist.net/bitcoin-energy-consumption/

By contrast, various sources list global datacenter power usage as "just" ~200TWh (e.g. https://www.iea.org/commentaries/the-carbon-footprint-of-str... or https://energyinnovation.org/2020/03/17/how-much-energy-do-d...) and it's likely the average datacenter isn't as reliant on coal power plants in china as bitcoin is, so I'd say it's at least plausible that bitcoin by itself emits as much if not more CO2 than all the worlds datacenters combined. Let alone just teeny singular sites like youtube.

Of course, if you're going to include client power consumption, that's a different story... Then again, a youtube video is an actual desirable product in and of itself, whereas a bitcoin transaction is not; it's just a way to (perhaps in the future) acquire something desirable.

Ideally we'd price carbon conservatively (i.e. higher than necessary), and then this would all be a moot point. However, by the time we get all the relevant countries on board with that, and get democrats and republicans to sufficiently cooperate (even harder), the universe's heat death is likely nigh, so perhaps in the interim it's reasonable to just outright ban exceptionally pointless wasteful activities such as bitcoin mining.
if the research is done with public information, of course there is no issue. If you go, for example, dumpster diving on shredded company documents then it might be an issue.

Note also that there are difference between US and EU. I think US might require a breach of duty of care somwhere in the chain of responsibilities for insider trading, while EU doesn't.
It’s immediately relevant to the very beginning of the article.
Lol.

On one end of the spectrum we have environmental groups making objections against every tiny detail.

On the other end we have - “Highly poisonous gas escaping the factory into the environment? What evidence is there that it is a serious problem?”. A very Nestle approach
What community ?

You can also think about the larger scale. We could open coal mines and gas/oil pipelines to create jobs, it would help your "community" in the near future but if we all continue to do that there won't be any community to care about in the distant future.

Also, with 5% of unemployment Germany is hardly in need of God Emperor Musk and his humanitarian help

'Arbitrary' code in this case is your 'any code on a clients machine'.

A vulnerability that lets someone run arbitrary code means they can run whatever code they want; that's what makes it such a problem.
Well in my country we don’t care because we’ll just borrow or print more and tax while we’re at it. I can’t count how many times Biden said “not spending enough”. So I guess I misspoke, we do care about how much we spend, but mostly that it’s as large as possible so we can use it as an excuse to increase taxes further.
Free as in "free speech", yes.
That's actually pretty funny. The same people who want "green energy" end up opposing wind turbines, nuclear, solar and hydro energy.

And what is left? Of course dirty coal and gas?

And which gas? Of course fracked gas imported from the friends from the other side of the planet instead of natural gas imported from the enemy nearby.

I think the best representation of the argument is that if governments couldn’t print fiat they wouldn’t be able to fund huge militaries and we’d have less destructive wars.

It seems fairly utopian to me, given that wars existed on the gold standard too, and if they were less destructive it was for want of technology. But maybe if I held Bitcoin I’d be more inclined to believe it was the solution to world peace.
