The makers of high power battery stoves maybe?

For those who don't know these are stoves that have on board batteries allowing them to generate, for a period of time, far more heat than an ordinary house circuit would be able to power. This replicates some of the advantages of gas.

But honestly I think the ban gas stoves thing is brought to you by the same people who gave us bans on plastic straws. "Let's maximally inconvenience people for extremely tiny environmental gains while ignoring huge contributors to pollution and climate change. That way we alienate as many people as possible and drive them into the arms of the far right."

See the problem is that the far right is so ridiculous and repellent that the left is having to work really hard these days to lose. They're having to push for things like banning gas stoves or the word "field" to have any chance at losing to the people who brought you Qanon and January 6th.
Could residential hydrogen generation, storage, and use be viable? Say you have solar, a water supply, and a big hydrogen tank. Any excess electricity can make hydrogen by electrolysis and store it to be used for heating and cooking. No expensive transport or exotic fuel cells. In arid climates the water vapor from burning it could even be captured.

The two big problems I see are that hydrogen is trickier to pipe than natural gas, and if there is no hydrogen economy to make backup deliveries, how do you keep up with essential heating when there isn't much excess electricity?

Unblissful Ignorance
Studying is not solely about acquiring new knowledge - but about reducing our ignorance.
Surprised about the FB thing, it has been as good as dead in the Eastern European country where I live when it comes to interactions with friends and family. No-one posts personal stuff on it anymore (and that's a good thing). I personally still do use it as a reddit-replacement, i.e. commenting on news items and the like.
I’ve done this recently. Essentially created a browser extension that combines Mastodon and Twitter on twitter.com. It works surprisingly well, but I’m guessing catching up with Twitter.com changes is bound to be painful.

(author). I agree with your sentiment , and try to make this point in the article. This is why I suggest using out of the box admin frameworks and other ways to provide quick admin features. Only spend time adding custom functionality once a need arises. With this approach you already have the frameworks setup, tested, and you have been writing your code with support in mind.

This is why I love the simplicity of C (C99 in particular). I remember back when I started learning C++, after years of experience writing C, I was admittedly turned on by the cool features like smart pointers, standard data structures, etc., but once I read/wrote any significant amount of C++ code, the “deceptively simple” code quickly turned me off and had me running back to C. Suddenly, nothing was what it seemed. With C, I could jump into a codebase, and within a few hours/days, I’d have decent enough understanding of what’s going on, whereas C++ had me constantly wondering . . .

- If certain operators were being overloaded

- How memory was being allocated in different sections, libraries, etc.

- The different semantics of the various ways you can do the same thing (e.g., constructors)

. . . the list goes on and on and on.

I’m not trying to crap on C++, but for a low-level language, the simplicity of C is simply unmatched!
> There is nothing "psychotic" about signing up again and adding some old friends again

Maybe not so extreme but if an old friend added me on Facebook I would immediately assume they want something…

But I have to say, I still have Facebook on my phone, and open it from time to time, and it’s pretty barren. I think the consensus among my peers is that sharing something on Facebook is signaling that you’re socially undesirable… so if he signs up again, I think he will find it doesn’t help at all.

(Though I still like Facebook as a contact list of last resort)
when i was a kid trying to dial bbs numbers by tapping them out with the hook switch was like its own form of entertainment.

there were other variables to contend with on those old at&t phones everyone had, as the pegs you release to off-hook the phone moved faster than the switch under them. this means you had to tap fast enough for the CO to see them as dial pulses, but also slow enough that the peg and switch mechanism doesn't separate and cause inconsistently timed or missed pulses.

My dude, if you think I'm signing up for the thing which made you estimate the probability of something you know nothing about (while also warming up to antivax conspiracy theories) you have seriously misunderstood this exchange.
Interesting. But I'd question the link between the anatomical change and the better memory for places. Navigation is not just a memory task.

The idea that size matters in terms of neuroanatomy is problematical. I distinctly recall that there are people missing entire regions of the brain who have no impairment whatsoever.
i left stackoverflow years ago. at the time i was one of the highest rated C++ answerers, but got fed up with the new company direction and insane moderation, but i haven't really missed it. i have recently rejoined just to add the odd comment on the C++ tag. several people have welcomed me back, so i don't really thing there would be a problem with this guy re-engaging.

An advantage of alternatives to rockets would be that they do not contribute to destroying the ozone layer.

Restoring the ozone layer by dispersing ozone could be a useful idea, but all it requires of material is oxygen, which we have plenty of right here. Neptune has nothing extra we need. The sun turns oxygen into ozone by the gigaton, today. To really address the problem, you would need to remove the fluorine compounds that consume the ozone. Nobody seems to have a better idea than not to vent more.

The space elevator notion relies on discovering a material strong enough to build it of. Other schemes seem possible with existing materials.

Neptune has helium-3 that might someday be useful as fuel for aneutronic fusion, if we can get that to work. Hardly anybody is trying. Getting to Neptune and collecting it seems even harder than getting aneutronic fusion working.
I think “most” is a bit of a stretch. Even in countries where education is free, or close to free, students still need some means to support their daily living costs. So that means loans or part time work. Having all of that handed to you doesn’t feel like it promotes the idea that university is an investment you’re making in your future. And otherwise I’m not that supportive of “free” higher education. I certainly agree it shouldn’t be cripplingly expensive, but the last few decades have demonstrated that shifting more and more young people onto the higher ed track just devalues a degree for everyone, stigmatises those who choose a different path, and raises costs for everyone. I also strongly disagree with the idea that having some/many diplomas automatically makes one “smarter”. That’s just a normalisation of credentialism, in my opinion

Having now read through some of this persons comments on the thread it seems a huge area of regret for them is that they didn't export the content before they closed their accounts.

That I can understand is upsetting much like not having backups of family photos and the drive dying. Why they did not export their content I do not know. Facebook, etc. have all had "check out" functionality for many years now, all before the pandemic hit.

Seems they rushed into closing their accounts rather than exporting and backing all those memories up and without any kind of plan on what to do to fill the social void it would great. As a commenter wrote in reply to them "I gave up eating McDonald's everyday but now I have no food."
> technology is ultimately evil

If we stop pursuing technological progress, we'll never be able to reach humanity's true potential. If we keep pursuing technological progress, those futures are still possible. We need to be wiser and mature about the way we pursue it but we still need to pursue it.

It was not that. It was because the round shape discouraged weathering, and the silicate composition resisted any kind of chemical attrition.

A lot changes, in millions of years. A lot of what we think of as "the surface" was once underground. Entire mountain ranges rise up, sublimate, and weather, in millions of years. Continents drift around, etc. The Appalachian Range was once taller than the Himalayas. Mile-high glaciers once shaped the land (not that long ago, too). I live on glacier poop.

It's pretty hard to actually grok epoch time. My mother was a geologist, so I was raised with it, but it still boggles me, when I think of it.

It's entirely possible that we have seen "fossils" of artifacts, but don't recognize them, as such, because they have turned into rocks. We ignored fossils for most of human history.
What innocent looking change are you thinking of that becomes an issue as a result of this?

If your function is currently taking a parameter by-value, and you replace it with std::optional<T>, you're still taking it by value and doing the exact same amount of copies. No (new) issues from optional.

You only run into trouble if you do something like change `void foo(const T&)` to 'void foo(std::optional<T>)`. But in such a change, it's "clear" (insofar as C++ is ever clear about anything) you're replacing a reference parameter with a value parameter.

I don't think this is surprising std::optional behavior?

> The (typical C++ stdlib) problem here is that things that look deceptively simple on the surface may result in a surprising amount of activity under the hood

It's literally exactly what it looks like. The C++ stdlib didn't complicate or obfuscate anything.

I open the window and turn on the extractor fan when I use my gas hob.

It uses a fraction of the fuel that my car does. Easily less than 10%.

On the wooden characters. I subscribe to this point of view. Initially, I thought it was just the inability of the writer to write convincing motivations but the more I read it dawned on me that there is a serious socialist propaganda undertone in his brush when it comes to the Chinese characters and plots. Motivations are off and the discourse is as unbelievable as to make the characters seem like pure fantasy and not of the good kind. My opinion is that either he is hopelessly unable to escape the propaganda tone (with a serious reek of Young Guards) or he deliberately wrote (or rewrote) the offending parts to make the material more palatable to the censorship apparatus. The western characters in the novel are even worse. High notes on the scifi, abysmal on the human milieu.
The simplicity is part of the aesthetic. IMO the trilogy is more philosophical exercise than narrative, so if you weren't looking for that then it makes sense you wouldn't be too hype about it.

At risk of spoiling things, I do recommend you go til the end, it's quite a journey
I’m not sure if fear is the driver here, or something else. I think it might depend on how they went about leaving.

I’ve had friends leave social media in a very holier-than-thou manner.

Coming back for them wouldn’t just involve re-adding friends, but eating a lot of crow in the process.

But setting that aside, I do find the post a bit sad. I think it points to the fact that even while social media is making us depressed, the world changed so much with its introduction that it can be difficult to operate without it depending on your personality type, the nature of your current support system, and friend group.

And if you suffer from social anxiety on top of that, things are only worse.

I don’t actively use social media, don’t have the apps installed, don’t have active browser sessions, and use Firefox Facebook container, but I didn’t delete my accounts either.
I am very curious what the damages awarded to Facebook will be.

On one hand, none of the surveillance were possible without Facebook.

On the other hand, a lot of the people have public profiles, which is expressing interest in being discovered, and Facebook is acting against that. And the cost to Facebook for serving the scraping requests is very small.

He probably is, but it always surprises me that billionaires think they know when they will die.
[Spoiler alert I guess]

Having only read the wiki page for The Light of Other Days (now very interested in reading the book, thanks!), it seems you’re mostly right, with the difference in Liu’s work being that total surveillance of earth is achieved by an alien species from another galaxy.
It’s politicized too which is ridiculous. I’ve seen takes that being pro gas cookery is right-wing.

Yes, it’s obvious that gas heat and cooking could cause respiratory issues due to combustion.

As a gourmand though, cooking on a gas range is the best experience wrt temp control and convenience. I prefer an electric oven, and the heating system I’m impartial to, though radiant hot water is what I fondly remember from youth.
In case anyone is interested I made a browser extension which helps you transition to Mastodon. What it does is it injects Mastodon posts into your Twitter.com timeline so you can slowly but surely get exposure to more and more of the Fediverse while keeping the familiar Twitter UI.

> You don't have to go to absolute zero for social media to cut out the majority of the toxic stuff but still get some of the benefits from it.

Just turning notifications off for all of them is a pretty good balance for me. That way I'm only opening them when I think to do it.

I'd highly recommend that as a first step if anyone's feeling overwhelmed and considering what OP did.

> Why was Exxon able to create equal or better projections than the NASA?

Focus?

Climate change, and the elimination of the use of carbon fuels (oil), would potentially existential threat to Exxon, so they better know everything about it. NASA has a whole bunch of things to focus on in addition to climate.
This is not a benchmark of some model on cifar-10, it's a benchmark of the training algorithm.

But, model size and complexity also matters. MLP with backprop gets about 63% on cifar-10, for various reasons. So achieving 59% accuracy means this algorithm is about 93% as good as backprop in this case.

However, 63% accuracy on cifar-10 can be achieved with two (maybe three) layers IIRC. The output is a 10-way classifier, which is handled in one layer. If the output requires multi-layer transformations, then gradients need to be back-propagated.

As long as the batch activation vectors are trained to max separation (or orthogonality or whatever) at each layer, one output layer can match them to labels. But this is unlikely in problems where the output is more "transformed or complicated".
When you play with con artists in an unregulated marketplace, getting conned should not come as any real surprise.
But why focus on optional then instead of just passing anything by-value? And why not actually dive into when/where this could be of a concern and how to recognize it?

It seems like an article aimed neither at beginners nor experts.
I think the Australians might have a few objections to that proposal... As one of them, I know I do at least!

It is interesting how much more archipelago-like Antarctica is. I wonder if that would mean fewer interior deserts than a large continent like Australia has
>What is a "meaningful explanation" of technologies we have not yet created and science we have not yet discovered

The question is already not the right one to ask. Many technologies he thinks up flat out oppose our current understanding of physics, therefor there is no adequate explanation for them in any case.

Just to drill this point in a bit more because people often don't understand this: It's not just a case of "maybe we will discover new physics in the future that make this possible and the author writes in a sort of gap of our understanding", like good hard scifi authors, but more along the lines of "the author doesn't understand physics and this fantasy technology they dream up relies on apples falling up instead of down when you throw them".

99.9% of the time when any author writes something that is FTL-related for example, this is the case. It's really just a few authors who bend the rules in reasonable ways enough and then introduce good enough restrictions so it can be believably handwaved away.

A lot of physics related descriptions in the Trisolarian books are also wildly innacurate and based on an extremely superficial laymans understanding of physics. That section where they house a black hole in that one custom facility for example, ugh.

They are so very "not embarrassed" that they are embarking on a massive change in how they operate. Or, claim to be; we will need to wait and see if it really happens, and then, if it does happen, if it has any desirable outcome.

We can anyway be certain Google does not need unpaid help defending them.
Even if a company exits very successfully, ordinary employees may get almost nothing because of ordinary agreements and conditions for other investors. Dilutions, ratchets, drag, tag, earn-out, black-out, convertibles, preferences, preemptive rights, etc. etc. You may not understand these (I only understand a few); if you do, you don't necessarily know every condition that each other investor is getting; and if you know that, you have no control over future changes.

To be clear, each of these is a quite ordinary business condition with justified business reasons. There would be no intention to harm you, as your employee share is too tiny for anyone to bother over.

But such complications can result in you getting little, even in a big successful exit.
i have been using std::string for many, many years and have never needed to know how my specific standard libraries implement it. if i want to worry about performance, i do it by timing and profiling, not reading standard library code.
I never 'delete' them. I just add them to my ublock and then do not use them anymore. I also am very careful about which site I join. Social media sites come and go quickly and am I missing out a ton of stuff? sure thing. I realized it was consuming my time for other things I care more about. When many of these sites turned from trying to connect me to people and more to trying to outrage me with dumb things as that feeds 'engagement'. I got out.

I also add their sites to ublock as they are many times disguised advertising networks. "why yes I love seeing the last thing I looked at on amazon all over the web" /s.
Ask HN: Muslim Programmers, thoughts on Noor or other Quran software?
Ask HN: How can I stop pulling my hair?
On and off for the last decade or so, I've had a somewhat destructive habit of pulling at my hair. I am a man with naturally curly hair, and as a result I usually have a bunch of hair on the top of my head that stands up like a crazy scientist. Sometimes it stands up in a way that only wetting it and drying it downwards with a towel gets it to go down.

I spend a lot of time pulling my hair sideways and downwards, in what my mind thinks is an attempt to flatten it down in a neater way. But sometimes I keep pulling even when it's all looking okay, so clearly there is something else to it..

I'm conscious whenever I pull at my hair, as one or two do come out each time I do so. Thankfully I have quite good genetics and the hair outgrows my pulling, so no patches, but I realise that won't last forever.

I've struggled for years to work out what the underlying cause of this is. I'm not particularly stressed, although it seems to be triggered whenever I do something that gets my brain working, or in times of stress (which is quite obvious). I've always been pointed to "trichotillomania", but it can't be this, as I don't pull hairs out on purpose. It's not on that level of severity.

Anybody else had something like this?
And overcome it?

In the past I've overcome it, but it always comes back. It's like it's an inherent way of me dealing with something, but I can't work out what that is.

Lately I've also taken to biting my lips a lot, which could cause issues with my teeth and lips long term.

Could it just be a unique way of fidgeting? Am I in a constant state of boredom even if I don't feel I am?

I don't think it's particularly surprising or nefarious for WhatsApp to be paying carriers to become the default messaging client. That's just good business (unless you want to bring things like net neutrality into it).

The reason some exchange / sponsorship seems likely is that there's no option without WhatsApp. If you're a carrier, a GB WhatsApp data is the same load on your system as a GB of Telegram data. What's the incentive to make the most popular part of your product free?
