There are several comments here pointing out that RGB devices such as phones and monitors usually cannot make a narrow band of light around 670 nm.

But the article ties this to light absorption by mitochondria, which it says absorb [1] 650-1000 mm light.

Two questions:

1. If you use a narrow band source of light, does it really need to be around 670 nm, or will anything in that 650-1000 range likely do?

2. Would it actually matter if there is also light outside this band?

If it doesn't actually have to be narrow and only contain 650-1000 nm, then it might actually work with some RGB devices. There seems to be significant variation among RGB devices, though.

jlokier linked to spectra for iPhone X [2] and iPad Pro 9.7/iPad Air 2 [3]. The iPhone X with Night Shift at maximum has a significant output about 650 nm. The iPads have very little above 650 nm.

This suggests that RGB devices might work for this, but there is no easy way of knowing for a given RGB device unless you can get its spectrogram.

From what I've been able to find, it looks like Philips Hue bulbs just miss, with their red falling off rapidly near 650 nm.

Candles look really good for this [4], and I'd guess similar for fires. I wonder if this means that ancient people tended to keep better eyesight in old age then us, because every significant light source they had (sunlight, moonlight, firelight) had a lot of its energy above 650 nm?

[1] OT, but why the heck does the "b" in "absorb" become a "p" in "absorption"?

> Charging them results in incidents like the entire police force rallying behind the one and just not doing their job anymore

... which could be considered a win for the section of America that the police oppress.
Isn't that exactly what USA are doing for USA companies, eg trying to force UK to buy USA comms equipment (giving USA backdoors too presumably).
What support that Taiwan is part of China outside China? Everyone I’ve ever talked to about it considers Taiwan independence and under threat from China.
> Maybe one person (the author of the style tool) is completely happy with the chosen style

I remember there being quite a lot of community outreach to discuss pros and cons of all sorts of different rustfmt style options.

All of them were very thoughtful, and made what I think has ended up with a set of decent compromises.

> the social justice conversation in America

On Twitter...

There have been efforts, advocacy, and 'conversation' about lots of such topics beyond just what folks yell about on twitter.

Twitter is a weird little world, and it is not 'in America'.... and arguably there is very little 'conversation' on their either.
I'm on Mojave, where it also exists. I'm pretty sure that I remember it being around since at least the days of Tiger (10.4), and that the only reason that I can't vouch for it earlier is that Tiger is when I entered the OS X ecosystem.
Job Search Strategies (With Q&A
This is incredible stretching + straw man to frame this as a political boogey-man (socialism).

Do you consider EMT's socialist? They are non-police first responders. Why not make more departments like this to address the massive over-jurisdiction of police responsibility?
They haven’t directly done that, but what they have done is force American companies to form joint ventures with a Chinese company in order to operate in China.

This requires the American company to hand over intellectual property and trade secrets. And then, amazingly, some state funded competitor comes along doing the same thing the American company wants to do.

Would a Chinese company have this same problem entering America??? No.

We need to treat China the exact way they treat us. The entire western world.

Why is there usually an “IPO pop” when a company goes public?
I learned this in the early 90s on BBSes, MUDs, Usenet, and forums, before I even discovered the Web.

Everything old is new again. Twitter is fine. It’s people who suck. Exercise your own restraint and freedom to associate. Externalizing blame is to throw up your hands and to join all the other naysayers in yelling at clouds.
Hypothetically yes, but I'm not sure any common fuzzing strategy would catch that. Pure random mutations would never get this far, and code-coverage based mutation won't either. How to create a strategy that would catch this but not be rife with false positives and wasted fuzzing time is not immediately obvious.

I always point out the price difference for the two models of the Purism Librem 5 phone. One model is manufactured traditionally and costs $749. The other model is manufactured in the USA and costs $1999.

Americans talk about bringing manufacturing back to the country, but I'm not sure anyone is ready to pay 2-3x for their goods.
The issue is that millions are out of work, meaning they have no income and therefore no way to pay rent. Landlords depend on rental income to meet their expenses running the property, so they’re faced with either letting people stay rent-free and losing income, or kicking people out so those who still have jobs are able to come in.

Rents are coming down, but markets aren’t good at handling major financial crises like this, and lower rents mean nothing to those who are unemployed and can’t find work.

> One "pneumonic" that helps for the option key is that it looks a bit like a "fork in the road" (i.e. "an option").

Although I think that there's no official answer, there are other people who agree with your explanation: https://twitter.com/marcedwards/status/225601862756352001 .

(Also, I don't know if this was just an intentional joke, but you probably mean 'mnemonic', not 'pneumonic'.)
Like the article states, I think Tweetdeck is more powerful and more useful than normal Twitter. You can see a much broader and deeper view of the topics you are interested in, and see it both at a glance and deeply if you decide to dig in. It's also excellent for watching trends in real time (such as many people tweeting about a conference).

Your normal feed forces you into a much more "all or nothing" approach. Someone who often tweets useful stuff but also lots of noise, you either have to put up with the noise or miss their good stuff. In Tweetdeck, just their good stuff shows up.
Sure but optimizations are not fundamental. It is not even clear to me if phonics instruction (invented by some teachers?) was based on linguistics (a scientific theory).
It would be a painful transition but we must do it to avoid the extremely painful long term costs of continuing this horribly lopsided arrangement with China.
I don't like either of these. Keep it all on one line.
That's a partisan take and even Democrats have supported moves against China (though they have mixed support of this strong of an action). While China moves Uigher Muslims onto trains and forces sterilizations on them, we should probably be doing something more than just making them ad revenue.

I just looked into the economics of rotor sails.

On average, they save $400/day ($146,000/year) in fuel costs (2017) or about ~10% of fuel consumption. In real terms, it's not much.

They cost about €1-2 mil ($1.1-2.3). Under the most ideal circumstances, that is a ~8 year payback, which is fairly long.

In order for the economics to work out, oil prices need to be higher and externalities (CO2 emissions) need to be included in the price.
this is false, numerous EU countries have a similar rights, de juro or de facto. Exceptions and laws against hate speech do tend to be stronger.

The fact that you're making such a statement about "the EU" shows how misleading or ignorant you're being, since this is not governed by EU law for the most part.

I'd argue that most EU countries have stronger de facto rights, since peaceful protests in the capital don't tend to get beaten into submission like what happened in the Washington last june.

Yes. I would imagine prices would fall rather steeply as the amount of available housing shot through the roof.

I bet good money that the decrease in rental prices after a eviction-pocalypse would be significantly more than a stimulus check.
Not true. You heard of Tesla? Its doing quite well and has majority stake. Things have gotten lot better but it been buried under the propaganda
For very technical things, having the information is not the same as having the ability to manufacture. Some industries don't lend themselves to catching up rapidly, you have to go through all the mistakes yourself. I think semiconductors is one of those industries.

An example (unrelated to semiconductors) is China's failure to manufacture a decent jet engine even though they've been trying for 30 years. It turns out that the metallurgy required for a jet engine is more complicated than what is needed for household appliances. They aren't even dealing with incomplete stolen information, they have a license from Russia and the full technical information and still can't do it (although Russia isn't sharing their most modern designs, but China still struggles to make an engine with 1980's tech).
"Unopinionated"? This is nothing but the expression of an opinion.
... either that, or they dive the Dow by banning Apple products in retaliation, or they invade Taiwan.
Clearly, a company looking to evade responsibility of long-term effects is an admission there is a non-negligible risk. And weighed against personal risk, at least in the US, it makes sense for a lot of people to not even take the long-term gamble to potentially save an 85-year-old.

Maybe tons of people if not the majority don’t care or would happily take the vaccine - let them!

But it seems far too short-sighted to discount all the people that wouldn’t want to take an incredibly quickly developed vaccine (with debated and unproven benefit - does it provide immunity? how long?) for a disease that seems mild for most people.

This is much less clear cut than you’re letting on, while being obstinate about data which we don’t have.
>Cultivate a good set of accounts to follow

Man I'm so done with that. Even cultivating a group of accounts on say a topic ... they're still people so I get their angry rants about whatever issue. And I respect their right to be a person and tweet about what they want, but that's a double edged sword as far as my interest goes.

I really don't want to see a twitter spat, ever. Even if I AGREE with someone I'm following I don't want to see them act like a child or sort of yell at me / the world whatever concerns them at the moment ... I just don't, it's not helpful, I'm not learning anything, it's just yelling much of the time.

>Who has time for this?

Amen.
Could anyone in the 90s and early 00s have imagined that the internet would end up being one big competition for who can monitor and track their users best, just to run the most efficient ads, and that this value would be in the hundreds of dollars per user?
Maybe, maybe not. Is the potential benefit even worth fighting over? Style is just full of so many subjective details that every discussion ends in. And everybody has their favorite it's un-fucking-readable. My oppinion converged on "Fight it out and tell me what options in $formatter I need to set. Don't even tell me reasonings, just the options. leaves room". I'd rather drink coffee than have the next horizontal real estate vs. parameter alignment debate.

The argument to match clauses/scoping for example is weird in a world where a formatter automatically applies indentation. It might make sense when you have to manually check them on print-outs without an Editor. I'd argue GNU style fulfills that role even better or Horstmann if you care about vertical real estate (or be daring and combine the two). And now everyone hates me.
Right, it'd probably be more convenient to have ctl on the right side of the keyboard. I could see how using caps-a (b, f, e, r, s) to navigate the terminal could be easier.

Good, the US should reciprocate the treatment it receives from China.
What gets me is surely, surely there is some better solution here than handing out money to everyone who has a problem.

How many assumptions can be clumped into one headline. Can't let rents drop under market forces, can't let banks go bankrupt, landlords can't take a hit. Only the taxpayer can bear these burdens.

This is the part that should really upset the free marketeers. The market wants to change and CNN wants government to step in and promote stasis. Some might call it stability.

I don't think people should be out on the street, but someone responsible has to feel the pain for the mistakes here otherwise the root cause, whatever it is, will not be fixed.

General aviation (small planes) still use 100LL (low-lead) fuel.

Of course there are some newer GA planes that use JetA (kerosene) instead, but due to heavy regulations, it's really hard to make/certify new planes, so most people still fly 40+ year old carburetor planes.
Where have bail laws caused any issue in NY? As a resident I haven't encountered any such issues.

I wouldn't call "abandoning a neighborhood" a minor change either. It seems clear to me it's very much a calculated political move to do that so people can do exactly what you did - point and say "well we need police, look what happened without them". This should have no bearing on reform laws and abolition steps.
I don't propose propping up failing companies. I agree with others who have suggested that ensuring that individuals (i.e. employees/workers) are adequately protected so that the immediate aftermath of corporate failure doesn't fall on them. Remember: the usual reason why employees are not entitled to the same share of profits as investors is that "employees are not taking a risk". If we're going to start arguing that deciding to take a job at a company is just as much of a risk as investing capital, then the relationship with profit will need to change too.

But the implications go beyond the people who work for corporations that fail, into communities (possibly far and wide). I don't think there are policies that can mitigage this without damaging the entrepeneurial climate, which I'd rather not do. At the same time, the incredible ease with which one can start new businesses in the US, and the trivial availability of credit, almost guarantees that we have huge numbers of businesses that play valuable roles in their communities but have absolutely no resilience to negative economic shifts. I don't know how we fix that.
I'd argue Microsoft does not need a shakeup right now. Much like with Tim Cook & Apple, keeping things humming along nicely is all they need to print lots of cash for the foreseeable future.

I suspect, what will happen with TikTok is they will migrate the company over completely to Windows/Azure products internally, so that it's funneling a good deal of money back to the mothership, then spin it off into a stand-alone company. They'll make a decent profit off this.

This isn't MS's typical strategy, but it's not unheard of either. Since TT doesn't really compete with any of MS's core segments, but it also doesn't compliment any of them, I think this is the most likely scenario.
"China does not have the capacity to build a jet engine yet alone a commercial plane in service."

My point was that they are building a commercial plane (not with Chinese fans yet), as your usage of "yet alone" expressed some kind of dependency or sequence, at least to my non native speaking ears.
All this is leading me to have a stronger belief in Nassim Taleb's "The Most Intolerant Wins" theory[1]. Though, in this case there is no minority as such. China was intolerant to the US's ideology and exploited its openness for its own benefit. Now, unfortunately, it has come to a point where even US has to be intolerant like China to be able to get back at it. Thoughts?

The chinese govt is indeed throwing their weight behind developing a local semiconductor industry capable of rivaling TSMC. They are making heavy investment in SMIC for example.

However, at the same time, unfortunately the Chinese government doesn't play fair, and they are ramping up state sponsored industry espionage and hacking of American and Taiwanese semi-conductor firms to speed up the process.

This best describes China's perspective towards "technology acquisition"

“They want technology by hook or by crook. They want it now. The spy game has always been a gentleman’s game, but China has taken the gloves off,” said John Bennett, the special agent in charge of the FBI’s San Francisco office, which battles economic spies targeting Silicon Valley. “They don’t care if they get caught or if people go to jail. As long as it justifies their ends, they are not going to stop.”

More importantly, it's not even possible. In any war over Taiwan TSMC's fabs will be rigged with explosives and destroyed. Not to mention key personnel needed to run the fabs getting caught up in the crossfire.
Technically, making those things easier also makes SSTOs work since optimized multi stage orbits let us get to the moon where SSTOs are the default option to get off of the lunar surface. In a sense SSTOs are part of the current earth to moonbase to Mars strategy.
