If you find that shocking you would probably drop dead at seeing what Lisp programmers get up to with macros :)

Language flexibility doesn't obscure the readability of code. It enhances it. In a flexible language, unclear code is always programmer error, and programmer error is fixable. In an inflexible language, a lack of clarity can sometimes be unavoidable (e.g. java programmers forced to shoehorn everything into classes)
Harry Reid asks for more UFO transparency after Pentagon video relase
A license is different from a contract because there is a separate body of law for licenses and another for contracts, with different requirements.

A contract can involve a license, and a license can involve a contract, explicitly. But they are different things. You need a lawyer to explain precisely how they are different, and how they interact. (Many judges and many lawyers are not very clear on license law.)

But one important difference is that there is no need for mutual agreement or exchange of value, in license law. If you don't agree, you don't have the license. You start out bound by its restrictions, under the Law of the Land, and they are only relaxed by its owner choosing to relax them.
The problem is that is been a month now: not having an answer is flatly unacceptable governance.

>> If we want to get back to normal getting community spread to 0 should be the goal and we need to keep everything locked down to achieve that.

Do you know what that will cost both in an acute USD fashion as well as the geopolitical and economic chronic fashion? I'm legitimately interested if you've thought through the externalities of this plan.
I don't understand how people claim this is hiding huge levels of complexity. It's trivial syntactic sugar. If stylistically, you don't like it, oppose it on those grounds. But complexity? It is syntactic sugar for a function call.
> The only people buying this are those "grand designs" type people who are architecting their own house with say $1m build budget and want to be "eco".

Sad but mostly true in the US.

High efficiency appliances are market segmented as luxury goods, therefore mostly purchased by the well off, limiting the energy used reduction impact of the technology.

This is less the case in societies with high energy costs, like Japan or parts of Europe.

Heat pumps are not a new technology - they are air conditioners that can be run in reverse, and in a broader range of conditions.

As low as you wanna go baby.

For a practical/realistic example, a Vector Network Analyzer might consider anything from 15MHz to 50kHz as DC.
>> Air travel is down 97% even though they are no laws against flying places

Sure there is. It's called mass unemployment and closure of non-essential businesses. Why would people fly to branch offices if they're closed?

>> Conversely, you could argue that if you want to take actions that risk killing hundreds of thousands of people

You don't know this to be true. There is plenty of evidence showing lockdowns have limited impact, no impact, or even worse, exacerbate the problem.

I wish they'd drawn an outline around the "fuzzy star" for scale.
Yes, just in case the state curbs their's abruptly.
It might be unexpected because if you’re like me, you feel super dehydrated after a cup of coffee. It might not actually dehydrate me but I feel like it does. And water makes it feel better.
That has nothing to do with 2FA, has it? Having a recovery procedure that escalates up tp direct phone contact is the norm with or without 2FA. This system is probably older than the Internet, with banks operating on similar principles (of course, it escalates up to physical presence there).
If you can point to something about the situation that has changed since the shelter-in-place was initiated that would indicate it's not needed anymore, I'd love to hear it. The virus hasn't gone away, we don't have any medications to make it reliably recoverable, we don't have test + trace ability in place (anecdotally, even if you're symptomatic but not in seriously bad condition it's still very difficult to get tested, let alone if you're not), we don't have herd immunity, there is no approved vaccine, etc. If the Bay Area opens up completely, exponential spread kicks in instantly with a high replication factor and in a month it'll look just like New York.

We are not through this in any way, shape, or form, even if it sucks. We've bought some time. If we did reopen now we'd probably be better off than if we hadn't shut down at all, but it'll still rip through the whole population, and unless we're ready to accept that, we've got to keep measures in place.
Facebook investors launch third attempt to remove Mark Zuckerberg as chairman
"How can I learn an instrument without listening to music"
"How can I learn to write stories without reading books?"

Have you considered just reading the code? It's all available. Best way to learn is to look what the masters are doing.

And even complex software is typically just a collection of simple things together.

IMHO one of the biggest failing of many CS courses is that they never get above toy software. Would be much better to at least once dive into some production software and try to figure something out in a real code base.
You're wrong. Of course, anyone is entitled to think it's crazy to spend a lot of money on coffee at Starbucks.

But it's also perfectly valid to respond that it's easy to enjoy a delicious cup of hot coffee for not a lot of money.
But if the rates stay the same, then all we're accomplishing is slowing the rate at which we reach herd immunity. If herd immunity is the strategy we're pursuing, then we should lift restrictions enough to meet hospital capacity, so we can get to herd immunity as quickly as possible and get the economy back to something approaching normal levels of activity.

If the strategy is actually suppression and elimination, then the lockdowns are not working (at least not here in Oregon, where daily number of new cases have been flat for about 2 weeks; I'm not sure what things look like in California).
The mobile website's been broken for me for something like a year. It just shows "Something went wrong" with a Try again button that doesn't do anything. This happens for me on two different iPhones (a 6S and a XS).
It's an incredible class divide:

* Essential workers (who make less) required to work and get infected at higher rates, both at work and from their essential worker housemates.

* We permit anyone (even non-essential workers) to hire a nanny, but let no one drop their kid off at a friend's house.

* Deep pocketed businesses like Broadcom can just declare themselves an essential business and mandate employees perfectly capable of working from home come into the office.
Off the top of my head I can only think of the one where you need to merge two linked lists in sorted order. It seems like most fall into being iterative or recursive. The iterative solutions tend to involve mutations. Doing them functionally seems like a bit of extra overhead. I'd love to be wrong about that because FP seems to be mathematically superior

The author has no vision whatsoever. His solutions are just take the money from the rich and give it to people.

- How about building an extensive and complete rail system that covers the entire country? This would help people get to jobs.

- Building out high speed internet throughout the country. Just do that in one swoop everywhere (including rural areas).

- Revamp the education system from the ground up. It's all outdated.

I could keep going. This kind of stuff could be solved with the budget we already have as a nation, however.
It's a bit more complicated than that. What's being suggested here is that it would be possible for a bad actor to observe all Bluetooth activity over a large area. They could then use a diagnosis key to reconstruct someone's path through this monitored area, and then deanonymize that person by combining their path with other data sources. Later, an uneducated and hostile individual might somehow gain access to this deanonymized data and abuse it.
How do you find the prices? I’ve only ever looked on Amazon but even for new releases they seem to be considerably discounted from the publisher’s list price.
Another related issue is the copyright of technical standards incorporated into law. A selection of technical standards, especially in the domain of civil engineering, the standards on fire, electrical safety, energy efficiency, and test design standards, are effectively laws. The implementation of standards is explicitly required by the laws and there's no alternative. Yet, these standards are often sold for-profit with copyright restriction.

The implicit belief in the comment you respond to, is that the mitigation cost will "kill" more than a million people.

I suspect it goes to non-lethal costs more, and then its the usual problem of milli-morts against economic cost/benefit.
Trigonometric functions have existed for a long time. And in the past, more trigonometric functions were used:

- versed sine (versin) and versed cosine (vercos)

- coversed sine (coversin) and coversed cosine (covercos)

- haversed sine (haversin) and haversed cosine (havercos)

- hacoversed sine (hacoversin) and hacoversed cosine (hacovercos)

- exsecant and excosecant

Perhaps I am forgetting some. Many alternative mnemonics exist for these too.

This formula was very important: https://en.wikipedia.org/wiki/Haversine_formula
Yes, they're temporary. The concern is that if the shut down ends soon (seems unlikely but who knows) then it will delay an economic recovery until the temporary benefits expire. For a faster economic recovery we would want as many people getting back to work as possible. If you make more money not working, the rational choice is to wait for the temporary benefits to expire and then go back to work.
If you oppose JSX, then you should doubly oppose Angular Templating language, since that's an entire language construct that gets compiled to JS function calls. Broader point: We need some syntactic sugar on top of JavaScript for writing UIs. JSX is about as simplistic of an abstraction you can get it. It's incredibly easy to reason about its pre and post-compiled syntax. Not the case with other paradigms.
If we did not have patents, we wouldn't have to build in the current cities, would we? I mean to earn our living. But since we do have patents, we cannot escape the extractive system that corrupts public sector in order to secure rent and we have to build on our land lords land. Funny.
Economies are wrecked worldwide. Trump shouldn't be elected because he thinks injecting disinfectant into your lungs to do a cleasing 'should be looked into' while maintaining that 'I am a person with a good you know what'.
Lot's of small reasons.

You don't want to transport heat a far distance (thermal loss becomes too high), so keeping the vent for the refrigerator integrated into the unit is generally better than shipping it off outside.

CoP is the lift you get from a heat pump given a specific delta-T. The smaller the delta-T (like an air conditioning unit's 90F->70F), the more efficient you can make it. If you group a bunch of components together with different target temperatures, you'd either effectively have 2 lines (so 2 systems), or run the system at the lowest temperature you care about. 2 systems is what you have today, and 1 system with high delta-T would have a much worse CoP.

And other reasons...
>although many of those selling on that platform still use Amazon for fulfillment.

That’s what makes me weary that there’s any way you can truly avoid Amazon. For many sellers it’s just easier to outsource their warehousing and fulfillment operations to FBA and use Amazon’s warehouse as a 3PL (third party logistics), and I wouldn’t be surprised if <random eBay/Shopify seller> used Amazon for fulfillment purposes.
I've been trying to justify this (along with finally buying an ipad), and my main problems with it are:

- It feels like a missed opportunity to solve an ergonomics problem where the ipad could be raised higher to eye level. I realize this would require more keyboard weight though. It feels a bit odd to see photos like this: https://www.reddit.com/r/ipad/comments/g61v3c/twelvesouth_cu...

- The usb-c port on the hinge is strictly for charging only since ultimately it connects via the smart connector.

- It's a stretch but it would've been nice if the keyboard was wireless (like the brydge) so one could connect it to other devices.

I get that I'm likely not an ideal ipad user here though, but it seems like microsoft was stepping towards with their whole surface neo concept.
I'm surprised to see Fermi National Accelerator Laboratory listed still. When I last visited Wilson Hall which must have been nearly a decade ago now, the pendulum had been removed. If memory serves it happened after the cable snapped from wear and they decided to just get rid of it.

This [0] post claims they removed it in 2010.

It was kind of mesmerizing to watch back in the day, Wilson Hall is a tall building with an open center, it made for a great Foucault Pendulum.

GP specified in scientific discourse. It's fine to discuss non-scientific ideas -- just don't call it out as science.
And measures were not limited to Wuhan. By the time restrictions were lifted in Wuhan, the Chinese government had implemented quarantines, surveillance, contact tracing and testing procedures throughout the entire country. While here in the US we have a hodge-podge of approaches from each state with varying success, and no restriction of movement. Not saying we should adopt authoritarian policies, but we'll only have the virus under control when every US state has it under control.

If you really like cooking on gas (I happen to) the expense of running a propane range is insignificant compared to the amount of propane you'd burn to heat water or a home.
You get natural gas delivered? What’s so special about propane anyway that it’s the defacto portable gas?
It’s a nice touch by The Guardian to write this article but given how much Amazon has benefited from this epidemic, I do not think any kind of individual vigilantism will really work here. You’re not even a drop in the bucket for them and most people do not care.

If anything, thanks to them being a go-to platform, they’ve single handedly allowed a lot of third party shops to sell their inventory, and have come out net positive as a result. I don’t mean to sound as an apologist saying this - just stating the bloody obvious.

The “vote with your wallet” rhetoric doesn’t work. It’s half past feel good bullshit. If you want these companies to change it must be codified into the law and backed up by hard time.

But good luck with that, since China is a massive trade partner and every country is turning a blind eye to them imprisoning people in concentration camps and harvesting organs. It’s unlikely The States are going to have a change of heart anytime soon.

The cookie thing is a myth most likely perpetuated by the cancerous advertising/marketing industry in an attempt to make the regulation look more annoying than it is.

Cookies for strictly necessary technical reasons (like a session cookie set when you log in) or those that contain non-identifying information like language or font size do not require disclosure or consent.

Oh the other hand, any tracking technology that collects personal information (whether cookies, local storage, server logs or browser fingerprinting) for non strictly necessary purposes (like analytics, A/B testing or conversion tracking) needs explicit, opt-in consent, and as far as I know personal information includes IP addresses or anything that can be used to identify someone uniquely with reasonable accuracy (so browser fingerprints fall in this category too).

When consent is requested, it should freely given, so if saying yes is easier than saying no (which often requires unticking hundreds of checkboxes one by one or waiting 30 seconds for a fake "we are applying your ad preferences") then that consent is considered invalid and you may as well just not ask for it in the first place because you're in breach of the regulation anyway, but at least you wouldn't be annoying your users.
The problem with 'this' (well, one concern): sometimes you don't have a choice. Suppose you consume a library, where you call a function, passing a function as an argument. Your function's this context can be overwritten, even if you don't desire it to be. I recently ran into this issue when consuming a third party library.
I manually exclude every single area around the world that I don't want to advertise in. This is the only real way to get rid of bad clicks from out of the area. Especially since the ads I run cost around $25 a click...
Thanks for sharing this. I've heard many stories like that of your uncle from professional researchers in science, economics, and other fields. This is something that people who have no experience in professional academia and science often do not understand.

In my experience a lot of people assume that because science and related disciplines are rational endeavors that the institutions and culture compassing them must also be rational, empirical, purely evidence-based, etc. Reality can be almost comically, and sometimes tragically, the opposite.
Lysol can destroy delicate coatings, so your screen won't be as anti-reflective, or your device's innards might be less waterproof, etc

That would work if there's just 1 person who is crossing the path, and you're able to physically identify them. If it's a crowd of people, you won't know who was what device unless their device is immediately next to the evil antenna. This isn't very realistic in practice, and is very unlikely to become common place world-wide. However, the virus IS already world-wide, and is a giant threat to many.

IMO 30 years or the death of the author, whichever occurs sooner, is long enough for the author to benefit from their work.

There really isn't any difference in terms of incentive for the author between 30 years and the current life of the author + 70 years (or whatever the current term is).
Why not build apps to build institutions?

Politics is quite complex and full of its own jargon. It is not simple to understand.

Why not to develop apps, which will streamline a complex political process? Take zoning for example. There are new construction hearings, which only few NIMBYists attend, while pro-builders do not even know where to search for those. Say I'm a pro-builder busy with my own career. I have many questions. Where are those hearings held? Can I attend them, or there are some requirements? How do I meet those requirements? Is there any voting taking place? Where is it actually decided whether to build or not? What is the next action I can take given I am an average city dweller able to dedicate few hours per month for politics? If there is an app that would bring the tasks down to small actionable points with descriptions, and offer simplest step by step instructions, I may find it actually fun to do.
I think that's because nothings different then when it all started. If we open everything up we'll just see new cases again

Love Pittsburgh, so true. Mattress factory / Warhol museum is also amazing.
This is the most legitimate criticism I've seen in the discussion. Hooks give you more control. 'useEffect' will only re-run when any value in the dependency array is updated. In class syntax, you have 'componentDidUpdate', but that function gets called after any prop or state change. With hooks, there is more granularity. Personally, I've found reasoning about hooks to be a learning curve that was conquerable in about a week. But there is no arguing, it requires you to mentally reason a little bit further than the blunt 'componentDidUpdate'.
