BEHOLD, terrifying 40 amp showers: https://www.screwfix.ie/c/bathrooms-kitchens/showers/cat8202...

Getting less popular now that tankless gas and electric heating is a thing, but they're historically pretty common in some countries. They're more efficient than electric tank water heating approaches, and arguably more efficient than gas tanked systems, sometimes (usual caveats for comparing gas and electric heating apply).

A major downside is that you typically can't have more than one, or at _most_ two, in one home. Some installations have a scary setup where there are two or more of them, but only one will operate at a time.
Ok, my definition of "weird" is: something that will get you marginalized under the prevailing norms of the society you live in. Something that is unusual, but doesn't get you marginalized, might be cool, but not weird.

Something that doesn't get you marginalized simply isn't weird.

In my experience, people who adopt a subculture do so partly to cope with being excluded from the mainstream. This is not always the case, of course, but I do think it's common.

The members of the subculture may be weird in my sense of the word (i.e. for the general population), but they won't be weird within their respective subculture. Within the subculture they will probably just be cool.
> solving the Schrodinger equation for anything more complex than hydrogen is more or less impossible.

Solving in the sense of an analytic, closed form solution to the non-relativistic Schrodinger equation (itself an approximation to QFT) using commonly accepted elementary functions. Even this requires actually evaluating the elementary functions to some degree of numerical accuracy if you want digits.

I often see this claim that only hydrogen is solvable, but I find it misleading. We have algorithms that will give solutions to the non-relativistic Schrodinger equation for helium to whatever degree of decimal precision you like (see FCI QMC methods) — how long these algorithms take to run is a different matter (see the fermion sign problem), but for helium it’s not too bad. The algorithms are unbiased, which I consider to be an exact solution.

You can think of it in the same way that we have Monte Carlo solutions to the rendering equation for global illumination. They are not closed form in terms of arbitrary elementary functions, but they converge to the exact solution over time.
Thanks for your thoughts.

Totally. Diversity and inclusion can end up feeling like and being a box to check versus a genuine effort to create change.

Process changes take time and can get easily derailed. I think about the small changes that can make a difference. Sharing resources written by black people, looking at your website to see if people of color are represented and giving solution oriented feedback if it isn't, asking for/demanding unconscious bias training for all team members...no act of inclusivity is too small. They all plant seeds of change.

Re: furthering the divide, it's interesting to look beyond the gestures of Fortune 500 companies esp to think about how their mission and model hurts or helps people of color broadly.
Only one side has pursued widespread restrictions on voting. We literally have a Republican president lying everyday to the American public about voting by mail and doing everything he can to prevent it. This both-sides-ism may have once been true but Trump and the party that decided to follow him have killed it.
Vehicles are weird. I feel like we try to jam all use cases into one, when I really need three different things:

1/ To go to work and back. Same route everyday. Not very long. Currently use a bicycle, but I’ve used mass transit for these very common in-out routes in the past.

2/ Small local journeys. I can’t collect 6kg of wheat from the local farm with a bike or a bus. Taxi is viable if I could get them to wait 20 minutes while I hang around the farm, or perhaps I could use two taxis to get out and back, which seems wasteful and the market for getting a cab from the country back to the city is challenging vs the city to countryside version.

3/ Long distance journeys. City to city is easy and pleasant with mass transit. Harder with a family and luggage, especially if the destination is not in a town or city. Personal vehicle works well here, and it’s getting more common to be doing long distance journeys from suburbia to non-city destinations, for me.

It felt like I could do without a personal vehicle for a long time. I bought a petrol car five years ago and finally live somewhere where I need it as of two years ago.

Now that we’re all potentially migrating away from big cities (a real trend I see, albeit anecdotally) I feel like my ideal fleet of personal vehicles would be:

a/ big lovely slow commute bicycle

b/ local BEV for cargo

c/ something else for long range

What would be fantastic would be to combine b and c. Something where I could carry a few kg of 18650s for a 10 mile errand range, and load it up with 1000kg of cells for a 400 mile round trip (or 500kg if my parents would foot the bill to recharge the long-range incarnation of my mythical modular BEV, something which feels socially unviable with anything other than trips to see close family.)
The windows model is that you get a binary-only driver that works with the current (certified for that component, etc) version of windows. You maybe get one or two updates over the next half a year. Then nothing.

If there is a bug, exploit, whatever, good luck. If there is a newer version of the component with a minor difference (e.g. different range of serial numbers, different device id, etc) usually the newer driver won't work, so no bugfixes for you. However, you can keep on upgrading your windows version, at least within the same Service Pack and major version, sometimes longer, because the age-old driver will continue to work.

The way to emulate it would be "have a binary compatibility layer for kernel modules". However, this gets you old, broken, weird and incompatible drivers that just happen to run with the new version if you are lucky. Also, because every vendor will reinvent the wheel while doing the minimum amount possible, drivers will be less capable, come with weird special tools, crapware and a generally bad compatibility to devices from other vendors.

Believe me, the grass isn't greener on the other side, just different.
Also, better keybindings and a table editor to die for.
These guys can be goofballs and only appear competent on the surface. Referrals can be job security as well, and you won't get referrals if you intentionally write bad code.

In other cases, it's skilled people that just don't want to apply 100% effort and are just coasting, maybe for external reasons (some folks can write decent code without 100% effort in the moment due to practice beforehand).
It's difficult to summarise but the last 30 minutes is where they have a really good argument, starting about here: https://youtu.be/Boj9eD0Wug8?t=3981

It gets quite philosophical, and hinges on whether people basically come to lose their own free will if embedded in a powerful algorithmic communication engine. They disagree with each other and there are definitely weak points in Zuckerberg's argument, but it is an earnest and principled-sounding defence. I think he loses the debate overall, but it's easier to attack his position than propose a coherent alternative.

There is also a part somewhere where Zuckerberg claims that when the platform takes actions such as marking a claim as untrue and linking to a source, that conspiracy theorists just use that to double-down and claim that the platform is trying to suppress their truth.

Youtube generates several minutes of video per wall clock second. Now many of those videos are innocuous, but one must assume that occasionally someone uploads a video of a street fight or something more grotesque that is of interest to law enforcement or intelligence apparatuses.

That's public. You can analyze all of those. The NSA is free to pull them just as much as you and I.

And they don't as far as we can tell. Is it the cost of analyzing that much content? Is it that the NSA doesn't care? Is there something difficult about stripping audio off a video for keyword spotting?

Well I have a theory, and the theory is based off what little comes out of that side of the community. The theory is that the NSA can't meaningfully process the data it ingests. There's too much, it's too hard to query and they hit the same roadblocks of telling the difference between an actual crime and a videogame or fiction story.

So then we must ask, why do they want more? They have more data than they can analyze, why even bother ingesting more? It's not because it helps their mission, it's not because there's some value to it.

Well, why do we see, regular businesses fall into this trap? A billion points of analytics data that they can't make sense of. When I see it, it's because it's easier to blame a lack of data than to explain the difficulty of the problem. You can always say "Well I just don't have enough data" but it's much harder to explain that a bunch of crappy error-filled data isn't good for anything except wild goose chases. Adding more bad data doesn't improve the quality of your data, it just adds more of it.

I am Brazilian, I tried to get jobs in other countries multiple times and many times it failed due to reasons not related to my competency:

1. Rejected from working in a gamedev in Europe because I am not EU Citizen.

2. Lots of companies on USA have to follow some crazy tax rules or general regulations that make them not allowed to hire foreigners, don't even need to be military stuff. Noticed some companies won't even hire out of state.

3. Military, healthcare and many other industries for obvious reasons don't accept foreigners.

4. Several companies have some for reason or another have all employees working on the same time, meaning they refrain from hiring outside their timezones (thus no California companies for me, and no Europeans either)

5. A bunch of times had problems because mismatch of required education and how education work in different countries.

By defenders, I mean those not associated with law enforcement, who defended people or property from harm or damage during protests. You seem to really believe in capital T truth as something that can be known by you and by others including police in a large protest, or riot, or looting, or all of the above. I don’t share this belief in Truth being knowable in the field. That’s why police don’t have unlimited latitude to identify criminals and respond to suspected criminal acts in the field. They must act within policing standards set by the community in stated and unstated ways. Otherwise, they may not have a job if the service they provide is made redundant through community involvement in legislatively changing police mandates, authority, and priorities.

But more to my point, police are not judges, lawyers, or most important, juries. They don’t decide what is just. They just deliver those suspected of lawbreaking to the judicial system, which determines guilt or innocence under the law. As far as the legal system is concerned, everyone has presumption of innocence. The way you are characterizing people as looters or rioters is to say that what they are doing is unlawful, but that’s just like your opinion, man. One person’s rioter is another person’s edgy protesting neighbor. It’s for the courts to decide which behavior is law-abiding. If they aren’t convicted, they were not found to be in violation of the law, yet. It’s strange for you to presume they would found guilty just because you disagree with their actions. Sounds authoritarian to me and not in step with our justice system or the times.

> Most still do not have an independent online ordering function. They want me to call.

There's the significant chance that most of the restaurants you have to call are running at such thin profit margins that they don't have the money to spare to hire web devs or pay hosting providers, and even if they did, do you want to hand over your credit card details to some budget build order page?

It's also likely that the profit margins are low enough that the fees for something like Grubhub cut deep.

On the flip side, having to call somewhere really isn't that hard, and to describe it as "a terrible experience" is a bit mystifying.

> needing to give my credit card over the phone

I don't think this is about camera phones, but digital cameras.

> I'm fascinated how people don't seem to be receptive to your promotion of positivity (by how you've been downvoted)

I think some of it is down to how as a species we are tribal by nature, and we have to work hard to get past that and start seeing one another as companions by default, rather than adversaries. There's a time and place for healthy competition and sportsmanship, but issues like politics, religion, and race should not be competitive at all (edit to say I get that politics is a competition/popularity contest, rather I mean that one should be able to support an ideal or a specific candidate without being seen as "the enemy").
> You don't want to be held hostage by your own code.

If your code is unmaintainable you become hostage to your own code because making changes breaks things, causes frustration, etc

I totally get the idea of job security if you’re maintaining a codebase that only you understand but that is very likely to bite you back quite badly, especially if you’re a contractor: you may not get any new work, the code you write is very visible and can be judged quite quickly by a qualified person

Yeah. Being weird isn't any easier, it's just that what is considered weird has changed. Being into computers used to be considered weird when I was a child (I was a "computer geek"). Now it's accepted and even considered cool. It's not that it's easier for me to be weird now, it's that those aspects aren't considered weird.

Things about me that are considered weird get buried on platforms like this. I've had many accounts here banned for it. I don't use foul language or attack people directly. It's just considered weird so it gets banned. I don't think it's easier to be weird. If anything it's much easier to have your life ruined by being considered weird. Take Richard Stallman, for example.

No, I mean the thing where it captures a short video (usually lower-res, I think, at least on the phone I have) at the same time as taking a full-res photo. The result is like something out of Harry Potter—you're looking at a photo, you hold your finger on it (at least on a touchscreen interface) and now you're seeing video giving a couple seconds of context, with sound, on either side of the photo. It's downright magical. I've got no use for a camera without that feature as long as my kids live at home, at least (a while yet).

"Live Photo" is what Apple calls it. I don't know if anything like that's available on other phone platforms, let alone stand-alone cameras, but last time I checked I couldn't find any.
