I don't think most people blame USA, it's just "progress". Yesterday at the supermarket I noticed the disproportionate ratio between healthy food (and I count there red meat) and junk food (snacks, sweets,...)
Subsidies are the reason HFCS is used in everything in the US, but sucrose is also cheap and isn't healthier than HFCS. I'm not convinced that the price difference between the two would significantly affect manufacturers' decisions of whether or not to include a sweetener.
Video Conferencing Is Broken for Many Physical Scenarios
You're not missing much. The story is about a house that got blurred out of Street View because a horrible crime was going on there at the time the image was acquired.
That’s literally a different argument though.

“After X days responsibility should transfer from the executive branch to the legislative” is completely different from “the governments ability to take X measures to stop a pandemic should be limited to Y days”. I am only responding to the latter.

My fear about the former is the implicit assumption that the legislature won’t also close gyms, bars, and other businesses that a vocal minority want re opened immediately.
If having a problem with callousness and bigotry is in itself bigoted, then yes sure, whatever.
How does that differ from choice #1, 'The reasons a policy was put in place. ("Why did we do this?")'?

A policy's expected outcome is correlated with why a policy was put in place.
> This seems to present some C++/Rust interoperability challenges which nobody else has faced.

Is this different from the Firefox integration with Rust in some meaningful way?

It looks like the cxx library is going to be critical for this. I’m curious how helpful others have found cxx for interop with C++?

> For a Rustacean, this is controversial - all C++ is unsafe! But “unsafe” should be a really bad code smell. If “unsafe” is needed for all C++ calls, there will be thousands of them, and the “unsafe” keyword will lose its meaning.

I don’t think the attitude about unsafe usage differs from the general Rust community. If there’s a lot of it, then it definitely is a code smell.
You can't blame this on Americans. Walk into any tiendita in rural Mexico and you will find isles of candy and sugary beverages, much of which Americans wouldn't recognize. Mexico loves sweets.

I'm glad they're recognizing that dietary health is a serious issue and trying to make changes. But I wonder what effect this will have on paleterias? They're one of the many things I miss from Mexico.
Whenever any website says "works better in the app" I always roll my eyes and consider it to be really saying "we really just want to spy on your data (apps installed, wifi networks, geolocation, accelerometer to determine your life habits, ...)"

For a site like reddit there is literally nothing they can't do with pure HTML/CSS/JavaScript.

Also, I like Firefox on mobile because you can block ads and install other extensions.

Well, if it's an illegal place what are the odds they follow CDC protocol?

Just open things up with strict masks / disinfectant / distancing rules and heavy fines for violators.

I'm okay with this answer as long as the people who go to the gym aren't allowed in the grocery store, bank, on public transport.... Because I do have to go there whether I want to or not. Give any gym-goer a 2 week temporary tattoo on their forehead so I know to avoid them. Then we're cool.
The PR strategy works because people believe in personal agency.
I mean, the real question would be - what would be the differences you'd want to see between unnamed new app and the existing ones?

That would dictate how hard it is. Anyone can make an app, Market penetration/usage is where the real questions await.

Put another way, what compelling reason could be offered that a.) entices drivers b.) entices endusers c.) technically feasible d.) sustainable
Exactly. The counterpart to this is walking up to a touchscreen credit card reader ten years ago and going "uhh..." while looking for physical buttons to push.
I think the person you are responding to is calling prohibitionism dangerous, not this consequences of this particular proposal.
Are we talking about China or United States?
I think they did it wrong by trying to maintain too much control over the drivers. Either that or people and/or their political representatives just aren't that interested in ride-sharing. But I doubt that, because as someone who is currently unable to drive, I know what a valuable lifeline these services can be. Fortunately I don't live in California.

EDIT: Also there's a problem with the way resources get allocated. I think that platforms of this type provide a valuable service, but not necessarily one that should be considered the basis for a billion dollar business. The majority of the revenue should be going to the drivers. But it's hard to get capital for something that has no chance of creating a few more billionaires.
When I was consulting I helped a lot of small companies deal with this type of situation. We loved Stripe when it fit the clients need, but it doesn't always work out. First, you should reach out to Stripe support to see if you can fit into their micropayments model which means you wouldn't be paying .30 + 2.9%. You can also look at some of the other platforms that support micropayments, like paypal (although I hate paypal).

Outside of that, many times what we wound up doing was integrating to First Data or another local bank clearing house that would provide more proper low transaction fees. It takes more work and effort, but clients saved huge percentages of their small payments many times by doing this, so if you can't fit into one of the existing solutions you may have to do it the "hard" way. Nice thing about this is we usually could accept e-checks (ACH transfers) when doing this which also lowered the fees drastically and made things more profitable. There are rules of course on industries, types of payments etc, but mainly if you aren't doing anything "illegal", porn or financial services you can generally find a good clearing house through a local bank. First Data's api used to suck, no clue what it looks like today but it used to be a royal pain.
Sure, but if the alternative is banning which is never a good approach, taxing it makes a lot more sense IMHO.

I'm no agriculture nerd but isn't much of the US particularly well suited to growing corn, regardless of subsidies?
News doesn't just mean new stuff. It is new information to people. If people don't know about it, it is news. Maybe not new to you, but congrats? I'm not sure what that solves.
Who should pay for the big shift to online grocery shopping?
I love that site. I'm currently working on the earth one. The spherical nature of the content means you have to wrangle with map projection stuff--which I thought I understood, but dealing with it in a puzzling setting is a whole new animal.

Highly recommended.
I wouldn't be sure of this. Google at one time was a darling of the tech world. Sure, the data collection issue has been there from the start because of the business model. But their products, engineering, openness was looked upon. Add to this their principled approach to things like when they decided to pull out of China because of their values.

The biggest qualm with Google was their incoherent product strategy like what happened with Gtalk, Reader etc.

If anyone had the brand value to push a smartphone OS, it was Google. Once Android started going mainstream, they could have chosen a different strategy for the high end models.
And people died because of them lack of them.

It's a pretty twisted definition of "essential" to include only the things that are definitely going to kill you if you go without and not to include the things that just might kill you.
Yes, the network works back from the signed key, which is published last. The TESLA scheme uses a one-way pseudo-random hash function to generate keys, see this paper https://www.esat.kuleuven.be/cosic/publications/article-2749... so if you know the signed key you can generate the others.

That means you can't easily fork a new chain with a K_6' as the receiver can easily check f(K_6') = K_5 where f is a hash function that is hard to reverse.

Once the key has been published, an adversary can use it to generate messages. A requirement in TESLA is that there is close time-synchronisation between the sender and receiver. This is enforced by the safe-packet test as defined in https://tools.ietf.org/html/rfc4082 which checks that the message packet was received within the time window expected from key signing.

As the satellite positioning systems depend heavily on highly synchronised clocks this is pretty reasonable.
Screwing people is inevitable. The only consolidation you can really take is knowing that the people you screwed at some point probably screwed someone else, and you're just continuing a cycle of karmic justice.
I wonder this myself. If I can ever be bothered to read a review of a mobile phone these days [which is rarely] it seems to be accepted as self-evident that ultra-thinness, huge screens and non-existent bezels are what everyone wants.

Not me. I want a phone that has a bit of ruggedness to it, will fit in my pocket and leaves some room round the edge of the screen for me to hold the damned thing, without triggering some unwanted app or function.
You say that like, if governments didn't impose restrictions, a new and highly contagious virus that can send you or loved ones to the ICU would not make people avoid crowds, spend less, and overall feel miserable.
I see no actual argument that her immunity is occurring, just a declaration and pointing to cases waning.

Couldn't there be other explanations for waning cases?
Feels like fanboy of Amazon wrote " yeah " this service + this service will be something sooo great, in practice ... Any satellite service solving last mile access and maybe potentially a bit low delay DC exchange when traffic is not very high. Means some exclusive, expensive service. That can be offered by any other provdier by purchasing similar package from Starlink or any other competitor.

In real life, lets be realistic Starlink is something will solve suburb access, also gives them an ability to exercise before Mars/Moon/something_else deployment. The impact on DC will be tiny.
I think few are willing to sustain a COVID-free lifestyle indefinitely. Using induction some people probably conclude that they might as well not bother.

I see the reasoning and don’t think the ethics of our pandemic behaviors have been fully discussed.
I worked briefly in the ISO 26262 space. While I don't have a copy of it in front of me, my understanding was not so much that you must prevent division by zero, as much as it is that you handle division by zero appropriately. Appropriately means that you can show that if you get a divide by zero, safety is not compromised. If I get an Inf or a NaN in a calculation involving cruise control, and I do nothing to handle it, do you think it will be OK?

More formally, if you have a potential division by zero and get an Inf (or NaN in case it's 0/0), you have to show what impact this will have. Can it result in a safety violation? If yes, what ASIL level would this result in? Based on this, you define your mitigation. It seems the safety folks have defined the mitigation to be "shut down the device". If you can show that there is a simpler mitigation, or that a mitigation is not needed (i.e. has no safety impact), then they should back off. This mitigation does need to be noted and documented, though.

Of course, this could be an organizational issue: Perhaps the safety folks are being the safety gatekeepers as a small portion of their job, so they are not willing to spend time to deal with nuances. I was the guy responsible for safety for my team, and it sucked - but I was doing it full time so I could analyze scenarios. The challenge was that the developers were not well versed with the ISO standard (had never read it), and it was a small portion of their job, and so they kept arguing.

> This is stupid because a division by a very small number has the same effect as division by zero.

As others have pointed out, this is not true. There is a big difference between a very large result and Inf. And of course, if a very large result could lead to a safety violation, then you need to handle it.

> For floating point, division-by-zero is perfectly fine and well defined by IEEE 754.

Keep in mind that conformance to the IEEE 754 standard is often not complete. Don't assume your language (or your libraries) are fully conformant, unless they are advertised as such.

Even if the ISO 26262 standard seems to have definitive language, I seem to recall there is a portion of the standard that allows you to waive requirements if the requirement makes no sense in your use case. There is a procedure to do it (documenting, etc).

FWIW, we did not handle Inf or NaN or divide by zero anywhere. We were writing a general purpose library for auto manufacturers, and it was up to them to decide where/how it would be used (called "Safety Element Out of Context" in the standard). Since we did not know the context, we argued that we can't assess if a division by zero would be hazardous, and merely noted in the documentation where it could occur. It's up to the folks who buy our libraries to then do that analysis. We only took care of things like showing there were no known crashes or hangs.

the patrons apparently don't believe that their behavior is unethical, and in fact, think that the dictates of their rules are unethical, and potentially illegal too.
Maybe they consider all carbs sugar? ~shrug~
There is a book called Sweetness and Power by the anthropologist and historian Sidney Mintz with a thesis that the way we consume sugar is not actually so arbitrary.

According to Mintz, the production of sugar was at the heart of the transition from pre-modernity to industrial modernity. Pre-modern human diets all over the world varied widely but consisted of very little or no sugar. The production process required a ton of technological sophistication and intensive labor. Colonial era economic slavery regimes developed mostly in service of the production of sugar.

Sugar is now a huge part of diets in just about every modern culture. It really is addictive in a sense, both for individuals and in a collective economic sense (like oil, sugar consumption and production processes are dialetically self-reproducing, the argument goes).

Myself, I don't really know if we should try to constrain sugar consumption via law for moral reasons. Those efforts sometimes reek of a moralizing paternalism that I don't much care for. But the way we consume sugar, like everything else, has a history. We didn't always do it this way. We need not do it this way forever. And there's more to it than just disparate isolated individual consumption choices.

EDIT - To summarize, the way we consume sugar today is not arbitrary or "natural," but an outcome of the particular way that industrial modernity has developed.
A lot of these seem tied to narcissism in some way. Not that it’s a bad thing but there are a lot of secondary effects of prioritizing ones “success” over all other things like relationships, friendships, mental health, etc.
I can think of a few systems in place that mitigate cases like the one you mention.

First, I can think of very few things that could happen to someone's car that would disadvantage you without disadvantaging them. In the case you mention, the missing tire would render the jalopy inoperable, and so the buyer suffers for their poor choice of vehicle. Any buyer thus factors reliability and safety into their decision, whether or not they are particularly concerned about the safety of others. Plus, now they have to walk, and you probably won't be giving them a ride. A counter-argument to this would be effect on climate, an externality that's maybe best left out for now :-)

Second, individuals may sue other individuals for personal or property damage. So, at least one factor preventing everyone from terrorizing you with their jalopies is that they are liable for damage their jalopy causes to others. The decision to purchase a jalopy includes this risk, disincentivizing the purchase of dangerous (to others) vehicles.

Third, it's already a requirement in most jurisdictions that drivers are insured because of the above liability, and insurance companies could easily deny coverage to unsafe vehicles, as determined by any (private) mutually agreed 3rd NHTSA/DOT-like party.

Finally, because there is no competition in the area of safety certification, it seems highly unlikely that the government's assessments of risk correspond to the risk assessed by the average consumer. The fact that most people choose to drive used vehicles that don't meet the government's latest safety standards feels like implicit proof of this.
I think the focus on nuclear power in the article is naive at best. Bechtel helps run the national labs, which work on (among other things) nuclear weapons and anti-proliferation. I would think it's more likely this would be for anti-proliferation work. Have a CIA asset walk near a suspected nuclear facility with this in their pocket while looking like a civilian. Collect radiation data, and if they get arrested or something, it's just an ipod.

It's a deeply unpopular opinion.

Healthy and unhealthy people alike like sweets. Just because some abuse it doesn't mean an outright ban is in order. And why stop at sugar?
It's certainly a lot more affordable.
The 'common defence and welfare' provide the reasons for taxation, and are enumerated in the following items. Note that James Madison — who wrote much of the Constitution — vetoed a federal works bill because he found it unconstitutional. The Wikipedia article at https://en.wikipedia.org/wiki/Taxing_and_Spending_Clause#Gen... is pretty good.

I think it's pretty obvious that the narrow view is the only defensible one.
No, it is actually both things. The sugar causes people to eat the stuff and does contribute to obesity, but sugar is only a contributer. The additives and ingredients like vegetable oils (which cause health problems of their own due to their chemical structure) also contain a lot of calories (fat contains more calories per gram than sugar).

In Australia obesity increased while sugar consumption decreased. The additives really matter and have a huge impact on human health--they are not a rounding error, but it was a great marketing tactic on behalf of various food industry groups to vilify sugar while deflecting from the other ingredients that are similarly problematic.

Coca Cola is very aware of the health issues and has been diversifying for a long time.

Around 2015 IIRC they got into the diary game with Fairlife milk, they own core power. They do lots of business in tea (gold peak and others) as well as coffee.

You can recognize the bottles for a lot of the products because they use the same one with a different wrapper - core power, illy, fairlife and others share. (Note: illy is a partnership)

I’ll also point out their zero sugar line, out since 2017, is fantastic - much better than the older diet technology in terms of taste.

> "...the existence of gray market gyms and parties is at least understandable..."

much of what you say is reasonable, but those two examples are actually quite different, and it's important to be careful with generalized pronouncements because of those important differences.

folks going to a gym can still distance properly, and so can still reasonably curtail transmission. the primary purpose of the gym is a personal workout, not sharing indoor airspace with others for prolonged amounts of time with abandon.

most (large) parties on the other hand are willfully defiant and reckless, with no intention of containing transmission.

gyms are fine, small get-togethers are likely fine, all-night ragers are overwhelmingly unlikely to be fine.

> I wish there were dynamic SRS decks for language learning (or other disciplines). Such decks would count the number of times you have reviewed an instance of an underlying grammatical rule or an instance of a particular piece of vocabulary, for example its singular/plural/third person conjugation/dative form. These sophisticated decks would present users with fresh example sentences on every review, thereby preventing users from remembering specific answers and compelling them to learn the process of applying the grammatical rule afresh. Moreover, these decks would keep users entertained through novelty and would present users with tacit learning opportunities through rotating vocabulary used in non-essential parts of the example sentence. Such a system, with multiple-level review rotation, would not only prevent against overfitted learning, but also increase the total amount of knowledge learned per minute, an efficiency I’d gladly invest in.

Exactly this is my side-project at the moment. Hopefully it will show up on "Show HN" in a year or two.
technically you patent the molecular structure too, and then take out a cloud of dozens of patents around it, while getting as broad language as possible (used for any disease where the pathology is influenced by this molecule, or whatever uspto will let you get away with) But generics companies are heavily incentivized to try and overturn those patents by law, and drugs are repurposed all the time through off label use without a phase III for the indication.
