There’s one aspect about the energy use of warm water that this article glosses over: warm water is particularly easy to store. Heat is also a byproduct of many industrial processes- reusing and storing that heat or warming up your boiler at peak energy production time is an efficient way to make use of “waste” energy. This significantly reduces the effective energy usage of any warm water usage.

There’s also ways to efficiently turn electricity into heat - heat pumps for example. These “produce” around 3-4 joule of usable heat per joule of electric energy. Just using a heat pump instead of an electric heater cuts the mentioned energy costs to a quarter.
And most fresh engineering graduates know nothing about real engineering.

You don't intentionally half bake the design, but you do intentionally try to exceed whatever your maximum design specification is.

The wing flex test, for example. 150% of the expected maximum flex the structure will experience during real operation.[1]

Even with software, you can't stop at "well I think this is the maximum load this service will handle in production." You need to know what will happen if that expectation is exceeded. Maybe nothing, or maybe your initial estimate was too high to begin with.

That blows my mind. I have no idea how the USA would react to something like that.

The link contains what seems to be a screenshot of the report. That screenshot says the report is preliminary, so I assume they do not want to state the cause in the preliminary findings.
This doesn’t work for political tweets. Look at replies to even Trumps benign tweets and you will see 50% of the population would hate other guy no matter what they tweet. Every single tweet of Joe Biden and Trump will get flagged no matter what they were tweeting.
it’s curious to me that you consider portland to be normally quiet - in the era of W and occupy it was 2nd only to Oakland on the west coast as being somewhat notorious for protest intensity, which was also worn as a badge of pride, and recently there have been several intense clashes between pro- and counter-fascist demonstrations.
> On top of that, the spec was massive, included a lot of kitchen sink style accumulation of language features - I can’t recall which feature it was, but I do remember when some language showed a new feature it was almost immediately shoehorned into ES4.

And in very many cases, too much was added too fast: the spec was _miles_ ahead of any implementation. You really don't want the spec getting too far ahead, as so many issues only become obvious during implementation, and you don't want to be building indefinitely on top of that potentially unsound base.
Not going to downvote, but I am going to disagree. For starters, most rankings have Oxford and Cambridge in the UK quite high up, and they run on a different model.

Next up, "liberal arts" today is not the same thing as it was a generation ago, and it's debatable whether it's still doing that much except credentialism (Bryan Caplan certainly thinks it isn't). This is not, by the way, a dog-whistle at social justice: I think that college SJ is a symptom of a deeper structural problem with the current university system.

The 25% who are going to fail (if the poster two levels above is right) are probably also not the Ivy League. In the UK at least, there are lots of places lower down the league tables who in my opinion could contribute a lot more to the nation if they were good trade schools rather than bad universities. Less sure about the US situation, but I think it was the case until not that long ago that there were ways to power and influence that didn't go through a university - including many examples of past presidents.
Please don't let these rather aggressive comments from Ruminator and others stop you commenting.

You put forward perfectly reasonable observations and it is frustrating when someone tries to silence others using the appalling Credentials Fallacy.

It is perfectly logical to say at the macro level our "take risks, move fast" strategy will produce more failures, whilst at the micro level being very disappointed at each failure.

Now, if this was a manned mission with life at stake I would expect the risk approach to be modulated accordingly. But even so, astronauts are not civilian passages and even they knowingly embrace flying at high risk. It would be interesting to know how (and if) SpaceX has approached derisking manned flight. Because the PR from blowing up humans is not good whether you're NASA or a private company.
The US have a long track record of using soft power and extraterritorial law to punish foreign states and companies, including supposed allies. The two most interesting cases where high profile European companies were targeted had something to do with US sanctions against Cuba and Iran.

Examples abound. Look at what happened to BNP Paribas. This is how it looks in a press release:

I think the is one of the easiest personal ways to reduce consumption. I challenged myself and have recently completed 2 years of no "continuous" showers.

Instead, I sit in my empty bathtub and use the spray only for getting wet enough to soap up and rinsing off. In between, all my lathering and scrubbing is done with the spray off.

As a person who loves long hot showers, this initially took some getting used to, but now it is my daily routine.
Of course the correct approach is the NixOS one. What docker really did is solve the packaging, distribution, and updating problem.

The dependency thing is just the fallout of the (bad) default provided by distributions.

How are people talking about a second wave? You have over a thousand people still dying daily and over 20,000 cases/day.

Protests like this one happened before covid for similar reasons. While those might be factors, I don't think they're very important ones. I think the fact that there have been several such murders in the past few months is the main reason this is happening.
Hi, I'm one of the founders of the movement. We talked about that a lot but it's not easy to define a framework in a specific way. For example, React is a library. But I think that most of the time people use it as a Framework. If you have some ideas on how to express this thing in the manifesto PR are welcome!
To be realistic about it I stopped calling things I don't understand "bullshit" and "terrible". What I use instead is "I don't know why it is that way", "I don't understand" and finally realization "OK, I don't want to spend my time on understanding this because I have better things to do".

I would love to spread this approach in developer community. Be honest that you don't understand stuff and you don't have time to learn it because you have better things to do.

Though if someone is paying me to do something in a language I will put my time into learning it. If it is just a hobby who cares that it is not easily grasped, I don't have to spend time on it.
The police brutality is relatively insignificant (though not acceptable). Every single time it comes up in these cases, the victim was either a stain on ordered society, or an honest mistake (see: Brenna Taylor) which are addressed fairly quickly. These riots are not due to "centuries of oppression" they are just bored and ignorant people lashing out because they have no focus in life other than victimhood and generations of indoctrination that they can't change things otherwise. No amount of justification exists for the behaviors exhibited by these rioters.

> The daily shower would be hard to sustain in a world without fossil fuels.

If this is really true, then I see no hope for us. Humans will not make sacrifices to their way of life voluntarily, and will politically punish anyone who makes them do so. When this comes before the voters, “I am the person taking away your hot showers” is going to be a losing stance.

We can’t “conserve” our way out of this. We will need a breakthrough in clean energy tech. We need a world where the energy for hot showers is plentiful and clean.
They're being down voted for the last point about Trump. He has nothing to do with this and is only doing a shitty job at [insert issue here] when you swallow the load of his opponents instead of apply critical thought.

With naturally skinny people having less flexible adipocytes does that not put them at higher risk of diabetes? Since they have less area to store the fat they will more quickly reach their threshold and start developing insulin resistance. Why then is there a classical association between obesity and diabetes? Or perhaps the definition of obesity is flexible depending on genetics?

On the topic of refined sugar my understanding was that because it is processed by the body more quickly it spikes blood sugar levels short and sharp rather than more spread out in the case of protein and fat which take longer to digest. Because of the limited rate of creating adipocytes this means that the same concentration of blood sugar delivered over a shorter time period would stimulate insulin resistance where if it were delivered over a longer period of time blood sugar levels would not cross that threshold. I'm sure that if you eat a caloric surplus that you will trip the threshold but could it not also be tripped by eating lots of high sugar foods to the same amount of calories of fat and protein which would not cross the threshold?

You'd think a bunch of educated folk would realize that if you can say anything at all, then you absolutely can breathe. Stop spreading this falsehood.
Is just an example. But could be an accurate comparison, yes

Repeatedly calling all the people in a country as lazy and unproductive is not an innocent move. Is parroting the racist slogans what other people said since decades whereas choosing to be blind to the easily verifiable facts. Therefore can be traced easily to drink from the same racist fountains, even if is of a soft, non-conscious type.

Dehumanization is a necessary previous step for racism.

From there is easily escalated to "they don't deserve it" and "they must be punished for it" and to "he tried to resist and I don't care if this hispanic scum can breathe (because in my mind is just a parasite)". Can you see the pattern?

Lots of people in Spain are as white as the whitest people that you can find in USA. I guarantee that you couldn't guess in photos by their look, who will be classified as "hispanic" and who will be classified as "white/caucasian" in the frontier.

US cops work in a dangerous environment; it's actually rather rare to get killed by a cop - much more often suspects (i.e. those who get in altercations with the police) are killed by criminals. So you can't expect police to be gentle in that environment; mistakes / bad apples will happen.

Besides that the framing is all wrong. It's not a racist issue - in any altercation the police are more likely to shoot white criminals than blacks. The problem is blacks have many more encounters with cops. And strong policing is most beneficial to black communities, where there is the most crime.

So the only way to solve the issue is reducing crime, which won't happen quickly.
My impression as well. I was thinking getting a career shift into pentesting (rumor has it that it's remote-friendly as well) but after a few job searches I came to see that the job market is tiny.

You cannot not have bias when you are talking politics. For Tweeter’s case, one would need to look at statistics for how many tweets from each sides are getting flagged. If one side is getting all the flake then it means that side is evil and other side is holy. In politics, this is not possible over long term if democracy is in full effect.
Out of curiosity, how does on forget to pay several parking tickets?

Normally, I'm a very forgetful person, but letting debt pile up is something I never allow myself to forget.

When I lived in Germany everyone paid their parking tickets religiously. In the UK you'd also have your car towed away until you paid your tickets with interest plus the storage and towing fee.

Laravel isn't an MVC framework. I often see people make this point and it puzzles me because even the creator of Laravel argues that it's not MVC.

Laravel has a "Model" abstraction, but its models are Active Record objects, i.e. database row proxies. The M in MVC is not supposed to be in 1:1 correspondence with your database tables. Laravel's Model class is poorly named.

The closest Laravel would come to being MVC would be by adding your business logic to service classes and adding them to Laravel's service container - an approach that the Laravel documentation mentions as a possibility but doesn't make a big deal of. Indeed, the documentation largely encourages the use of controllers to contain business logic.

Because in crypto, the math usually isn't mod 2^256. For instance in curve25519 you do do math mod 2^255-19, so they actually all fit in 51 bit.
I guess it depends on your frame of reference, but it doesn't seem like that much to be honest. It's arguably a really groundbreaking new thing that has been brought into existence in the world, and it took as much energy as a jet doing a transatlantic crossing? Or powering the LHC for a few hours. Fair price to pay if you ask me.
Zoom I've always thought must have pretty strong security if configured correctly (obviously that's a big if) It is currentLy in use by the Chinese Academy of Sciences (CAS). CAS is sort of like a mix of NSF, NIH, and DARPA all rolled into one. About 20% of their research supports the People's Liberation Army (PLA) for things like encryption research, so I assume they know what they're doing.

This is technically a white label I guess you would say, but if you download the code, a majority of the files begin with the prefix Zoom and what not: https://cc.cstcloud.cn

This is correct. Actual peaceful protests might have had some results, but this intolerable behavior by rioters is only turning many, many people against black people and "anarchists" in general. Could have had a consensus against police violence, but instead the reaction was and is far more harmful. More people's lives have been affected (or lost; see Louisville) as a result of the riots than the initial death.
This is a fantastic metaphor! I will use it in some talk!

Actually according to the autopsy, his knee on Floyd's neck did not cause his death.

That isn't what the autopsy report said.

The ME also claimed that the initial autopsy found no evidence that Floyd died of strangulation and traumatic asphyxia after Officer Derek Chauvin kneeled on his neck for more than eight minutes.

Correct, he didn't die of strangulation or asphyxia. Someone who can't breathe can't say things like, "I can't breathe." Instead, Floyd died of circulatory insufficiency, subsequent to having a knee pressed on his neck for almost nine minutes.

The medical details are completely irrelevant when it comes to determining responsibility for the outcome. [1] The officer is equally responsible regardless.

Tangent: I appreciate what they are doing with their solar-powered server, but they could make the site so much easier to read by removing the whole-page overlay to be something less obnoxious and irritating to read when half the page is yellow and half is not.

Perhaps a thing to let you "minimise" it so it only takes up a 1cm bar on the side, or a thing to just let you dismiss/hide it entirely?

Also for the image dithering, it kinda feels like they've gone too far with that - I guess it is a stylistic thing to have huge huge huge dithered images that at best don't fit on a single screen at once or at worst require you to scroll past 2 or 3 screen heights worth (e.g. "A 6-nozzle mist shower" one), yet with a resolution so low you can't actually read the text (NASA image)?

In my opinion it would be better to have higher resolution dithered images, that are just physically smaller and fit on one screen (I am using a 1920x1080 1x1-DPI so not exactly huge by modern standards but not tiny) so that the file-size balances out.

I found the article really hard to read due to the 50/50 yellow-not yellow and the absurdly large low-res pictures that I needed to scroll to see the entire thing but actually cant see because the resolution is so poor. Sorry. :(
I think it’s funny that people have an issue with this considering the site makes an incredible amount of money stoking fear and hate into people while purposefully looking for controversy anywhere it can be found.

Of the 100 articles on the homepage of The Guardian, try to find 5 that are not fear, hate, or controversy. Good luck..

Hiding = processing, so Twitter generates new content by filtering parts of the original content. Therefore, Twitter is a publisher and should be held responsible for all of its content. This should have been a no-brainer.

Don't be naïve.

(Which is orthogonal to the legitimacy of the protest itself).
The Tunisian revolution worked because the system was overloaded with protests in almost every single region of the country. Contrary to previous localized protests in 2008, that were more contained and effectively suppressed by the regime.

But it is also worth to remember that unarmed protestors rarely "just" overrun the barricades and enter the palace (figuratively). Someone with power (police or military) has to decide that they're OK with letting the protests go through, that is the signal of the end.

Perhaps. I don't think it's possible to be too certain about it - 'law and order' may not imply support for Trump, especially if you see him as inflaming tensions. Or it may result in larger voting turnouts in certain areas which may not help Trump at all. Who knows? It seems unpredictable to me, unless there's good precedent for similar events & election results?
