IIRC real-engineering on youtube did a detailed analysis of the current operating limitations with electric planes:
https://www.youtube.com/watch?v=VNvzZfsC13o

He also identified a couple of sweet spots where electric flight would make sense factoring in engine efficiency & cost of fuel etc. bottom line is that the picture is more complex than just comparing energy density of jet-fuel & batteries. with batteries becoming much lighter IMO it should open up many more use cases for short haul frequent flights without the need of big central hub airports. which is good. an more importantly give the trajectory of battery energy density it should provide enough justification for heavy investment into research into electric planes so i wouldn't dismiss it out of hand.
This works, but I feel like I get "staff picks" on Netflix or Amazon right away too...

Everyone has an opinion about what I should watch, and it's usually a horrible shallow opinion.
Is there some way to embrace this in the design of the plane? Could the wing structure be built in such a way that an expanding battery actually adds strength?

Ok, but then we have people doing solo activities, all by themselves, minding their own business -- getting arrested by lunatics[1] because we said no beach allowed during Covid[2]!

How do we reconcile that?

Roku TVs are a one remote solution with a minimally invasive OS. They have an interest in not killing their user base with dark patterns. It also won't be treated as abandonware two years later.
I don’t think people really shake their heads at kids disrupting meals (unless it’s really egregious). If a kid screams or something, people naturally look, but you don’t know what they’re thinking. They could just be wondering what’s going on, or remembering their life when they had kids that age. You have no idea. Mostly I would think that the parents are doing their best and they have enough to deal with without me also passing judgment.
You know, I could see—if this isn't out there already—a browser based on eliminating visual annoyances; essentially, something that operates a lot like iOS reader view, maybe like Brave but for popups and similar interruptions.

My current anti-crap shield is a patchwork of various plugins/utilities, most of which only work on my desktop: a plugin to turn JavaScript off (this alone eliminates about 90% of the nonsense, while preserving most of the valuable content); a bookmarklet that hides fixed-position elements (wipes out a lot of the popups/reminders); and a plugin that lets me edit a site's CSS so I can manually remove the junk that the first two methods don't. (Using adblockers and readability plugins goes without saying.) A browser with all of those baked into it—especially, say, something like smart popup removal—would be something I'd be willing to pay for.

I don't believe the web is headed for death; not yet, anyway. There are certainly trends that are deeply troubling, but for most of us, building a website is still far more feasible than building an app.
I mean, I guess you’re right. I’m the counterexample (grew up poor, have more than the zero of my one parent and my outlook looks good) but it took some time to get here. My college friends (all from wealthy families) are all well-off, but my friends from home are still poor and have poor economic prospects. But some of that is self-imposed because they haven’t put serious effort into economic pursuits.

I am quite tired of economic crashes, but I’ve failed to convince enough others to vote and advocate for changes. Those who do care about change are focused on matters other than economics, which I believe to be a mistake.
Ask HN: 8 Days Left on SlateJS Android KickStarter. 50% Raised. How to Complete?
The Slate rich text editor for React is, IMO, the best designed rich text editor with the exception of one major failing, it doesn't support Android.

My company spent CAD $50K developing Android support for the previous version of Slate with the hope that the community would take it up which I completed and which we contributed for free. This was after it was one of the most popular outstanding GitHub issues for 2 years.

Unfortunately, several months later the creator of Slate did a major (and really great and probably necessary) rewrite but it removed Android support and it's non-trivial to put Android support back in and that's a big cost for my company (which didn't even get a chance to use that version of Slate yet) to burden alone.

I proposed a paid plugin which many were in support of, but after receiving many requests for a sponsored model and a user committing to help raise the funds, I started a Kickstarter. Unfortunately the user that was originally going to help raise funds got a new job and was unable to commit to helping with the fundraising.

So far, there is CAD $10,500 raised out of $30K but I know that there is another $6500 committed coming in so we are at CAD $17K out of CAD $30K.

There's only 9 days left in the campaign. Any ideas on what to do, who to reach out to and how to reach out to them to complete this fundraising?

That is a comparison.

~50 deaths due to lightening strikes across all age groups. We were already close to 1000 confirmed COVID deaths for folks under 34 in mid-June.
This might sound crazy but is it possible to do that in some way such that the clamping plates etc. are only there during the charging process? Prevent the delamination during charging and then remove the prevention mechanism?

Or just charge really really slowly? Airports etc. could just have terminals full of trickle-charged batteries to swap in and out.
Maybe not but 'karma' in its original meaning of cause and effect is: if you hurt somebody, they will be hurt.
Interesting that you compare Stacker to compoxure. Will need to look deeper into it, but I see a few things Stacker does in a very different way, plus it contains a lot of things compoxure seems to not touch (which, by all means, can be a good thing, please don't misunderstand me).

I only speak for us at betterdoc -- we created Stacker in order to be able to create tools that can be stacked together like containers (the real ones used for shipping things) to form various workplaces. It enables us to mix and match tools without changing code - just by configuration - and we discovered that this is not just a theoretical option, but happens regularly.

The basic idea predates 2014 by far - one of the first things I have worked on back in 2006 was a portlet server (anybody remembering this?), and now we solve many of the problems we tried to solve back then, again, with a different approach and spin.

All I can say is that working on Stacker in the last years was fun, and developing services that serve micro front ends for it gets more fun and efficient with every small step we take.

Cannot wait to share more about the ideas behind it :)
No, Apple wants you to think they're the best when it comes to protecting user's privacy.

+1 to this. I saw a fellow parent dump their kid on an iPad whenever he fussed, regularly, for months. Seemed like he learned that he could whine to get what he wanted (the iPad) rather than learning how to play/interact elsewhere. All parents are guilty of something like this, but I remain firmly in the camp of not handing over the device just because my kid wants or whines for it.
Why is UBI the thing that plunges us into full blown socialism, and not the myraid of other social safety nets?
“In its majestic equality, the law forbids rich and poor alike to sleep under bridges, beg in the streets and steal loaves of bread.”

Most apparently-equal rules aren’t actually equal in their effects. Charging everyone the same amount usually hurts poor people more. UBI is one of the few apparently-equal policies that would likely help the poor more than the rich.
It's not the correct answer for division of the reals. For division of IEEE 754 floats, it is the correct answer, because division in that context is defined that way.
Distressed assets they think they can pickup cheap.
I think that explanation is more of a political talking point than reality.
I guess if you make people desperate enough, then they will start looking for new jobs. But I think he's grossly underestimating what's going on with society.

Most people on unemployment are laid off. They are not applying for new jobs because they assume that they will have a job to go back to shortly.

These people are also dealing with the clusterfuck surrounding schooling & childcare. From what I've seen, it's close to impossible to get your younger child back into childcare. The older ones taking remote classes in school require a good deal of adult attention.

I don't think a lot of people would change jobs even for a big raise because things are so hectic right now. Even people here on HN are struggling to balance their lives, and these are people who earn good wages and have a lot of flexibility with their schedule.
Back when I was an intern at Mozilla it was a real pain (in my opinion) to call between C++ and Rust. This was before bindgen and cbindgen, and certainly CXX.

Eg if you have a heap allocated thing that is passed between Rust and C++, who frees it? I ended up hacking something together, but it didn't feel right.
Long-term, what you might expect to see are structuraal changes rather than prohibitions.

Disease transmission is a communications and network problem -- there are the unobserved opportunities for infection, the known observed cases, the transmission rates, incubation and course-of-illness periods, acquired immunity, mortality, morbidity.

In periods of outbreak you need hightened disease surveillance, increased blocking of transmission, and reduced opportunities for infection. Barriers, reduced crowds, improved sterilisation and surface cleaning, fewer shared-touch interfaces (from touchscreens to bannisters), and the like.

These will likely be instituted through building and health codes, not so much activity restrictions. Some high-contact activities (bars, nightclubs, theatres, amusement parks) may well be subject to temporary closures. But expect these to be contingent on infection levels.

Do expect to see massive changes in office/work, retail, and transport designs, hoever. Possibly travel and quarantine restrictions.
>> Still orders of magnitude less energy-dense than jet fuel.

Does that matter, if other aspects of the system compensate with lighter weight? For example, lighter weight electric engines versus heavier fuel-burning engines along with exhaust and cooling systems.
UBI isn't socialism. The incentive for productivity under UBI is called capitalism, and it means that the people who want to live more than slightly above the poverty level will continue to work, and the people who want to get rich will continue to innovate and start companies. There are plausible (though obviously untested) arguments that UBI will increase innovation by getting people out of bullshit jobs and enabling entrepreneurs to pay their bills until their companies are profitable.
Simplest possible explanation: by writing this post, you've put more thought into it than they have.

Perhaps someone wanted to increase app install numbers (and/or user engagement), this sounded like it would work, and they did it. Simple as that. They did not ponder whether it might have negative effects. They just did it and moved on to something else.

Of course I have no concrete evidence of this, but with the state of product management in our industry, I can't dismiss the possibility.
That makes me think of the flippant quip: "Whoever dies with the most toys wins."
Actually this highlights a different issue--for photo editing, there isn't one "right" way to do things, like for instance text editing in like Microsoft Word or some shit. darktable has a very different approach compared to Lightroom for instance.
> Also, banning sales to children doesn't solve the real culprit - parents buying the junk food for their own children. At least in America, watch any parent fill up their carts and pay attention to what they buy.

I grew up in Mexico. There's definitely a culture of drinking soda with meals for example. Parent's are definitely responsible for that.

There's also definitely a lot of children buying junk food with their allowances. The individual bag of chips is very popular, and it's sold in every "corner store" on every neighborhood (I've seen less of these in the USA, but they're everywhere in Mexico).
> But do you believe there is a hard problem of the experience of three?

I think there seems to be a hard problem of any experience, be it red, three, pain, etc, because nobody has come up with a convincing way of how to reduce that to the physical.

> Do you ask whether the exact symphony that plays in your brain plays in mine when we look at the same three objects?

I doubt it does as individual brains differ, although there are likely similar patterns of neurons firing. This is why it's hard to reduce experience to brain activity.

> Maybe yes, and I'm misunderstanding what you think the hard problem is?

Making consciousness compatible with physicalism.
If people listened.

There's a genuine culture difference in America, call it American Exceptionalism if you want, that's caused all sorts of normal preventative measures to be ignored or actively rejected. Many businesses actively rejected the idea of requiring masks, today some businesses still refuse service if you're wearing a mask. That's pretty ridiculous if you ask me.

Moreso in this thread you have hundreds of comments hemming and hawing, nitting and picking at every detail of proposed lockdowns and mask requirements. People hate this stuff and they call it an imposition on their freedom.

In other countries people just put on masks and stayed home. They didn't make nearly as much of a fuss about it all.

Explicitly being turned away? I have not seen those. The New York Times did an analysis of the overall death rate, however, and setting aside COVID deaths, it is up. It's not an unreasonable assumption to assume at least some of those are lack of medical care for whatever reason.

You'll find California (and everywhere else) has loosened up substantially on outdoor activities, as we have substantially more information in recent months on outdoor versus indoor transmission. We've learned a lot since April about COVID-19.
It's established fact, albeit not very well known. It's not all births, as implied. Only hospital births.

The worst part isn't that they take it, it's that it's not disclosed to you, nor can you opt out[]. You can have the sample destroyed after-the-fact by writing a letter to the correct authority. We did so and a few months later got supposed confirmation of destruction and supposed confirmation that the sample was not used in any way for any purpose. Of course it's far better to be able to refuse collection than to trust that your destruction request was properly followed.

It would be acceptable (welcome, even) if the samples were properly anonymized. Clearly they are not, since you can request destruction of yours.

I mean, you can probably absolutely refuse while you are at the hospital. What are they gonna do, call in the sheriff?
Can you share the block rule?

> Ideally, you build an abstraction around the unsafe interop layer that rigorously enforces every requirement

I think that’s the reason that doc discusses using cxx, right?

> The Chromium document is right to call their idea controversial. Hiding the unsafety of the C++ code without actually doing anything to protect against malformed calls to that C++ code is a loaded footgun.

I agree with you, but at the same time, I think in this context, single codebase, abstractions built by the teams making the guarantees at the FFI boundaries... it feels like they would meet the requirements here? It definitely is less strict than Rust, but the way I interpret it is that they are saying they will guarantee the C++ is safe behind the abstractions (maybe they can mark the C++ In some way to state this), and that’s not all that different than what we say in general in Rust when we claim an unsafe call is in fact safe when we wrap it in unsafe.

What I mean by mark, is potentially use some annotation in C++ that cxx would only call into when that annotation is present.
My interpretation of the summary was that the researchers will follow the same kids later in life and see the impact. They are just reporting the current results. Per the article

"What we need to know next is whether this attention difference is advantageous or detrimental to their everyday life."

A lot of the comments on HN imply that the researches found a negative effect, when they did not conclude that.

I've been a software developer for years, and even prior, as a kid spent many many man-hours in front of a monitor.

I'm wondering from the HN crowd if others experience this self-dubbed "pixel vision", where when you look at a distance or don't focus your eyes on anything particular it seems like there are still RGB pixels twinkling at you. It's hard to describe sometimes because it's not an in-your-face, immediately-obvious-all-the-time thing. It's like a "soft filter" put over the world.

Ignoring someone is not depriving them of anything.

Human sacrifice is utterly barbaric and would be outlawed in a truly civilized society.
You're falling for the right wing deception here. This is a lot more deadly than the flu and the flu usually only kills those who would have died soon anyway.

What I find important to remember about minimum wage is that it constitutes a restriction on the freedom of workers to negotiate for their labor. The existence of a meaningful minimum wage implies that there are people in the society who desire to negotiate for lower compensation (because they are more motivated to get the job for whatever reason), but they are disallowed from doing so. It might be our opinion that it is undignified or exploitative to work for a certain wage, but we should not have the right to bar others from doing so if they wish.

As individuals, we should demand the freedom to negotiate the terms of our employment without government influence, including wages, benefits, and even working conditions. Using the government to coerce employers into giving greater compensation is appealing in the short term, but ultimately it disenfranchises others by blocking them out of jobs and results in long term economic stagnation.

Mandatory minimum wage significantly above the "natural" level dictated by prevailing economic conditions unquestionably causes harm, mostly to workers who, if they choose to continue to work for less money, are now doing so illegally. Mostly they just don't get work. This is why politicians tend to let minimum wages lapse behind the market rate - economies work better without this restriction. And when a significant minimum wage hike is imposed, like $15/hour in some places today, the economic harm to workers quickly becomes apparent.
To "live" at what standard of living? A smartphone? A recent one? What standard of medical care? What about entertainment? What if someone wants only to eat organic, fair trade food?

When you pay for yourself, you're price sensitive and try to choose what makes sense for you. When you're not price sensitive, you run into a major incentive problem. If your life is funded by taxpayers, you have no reason not to argue that basic subsistence requires a lifestyle as expensive as you can get away with.
