20% is the guaranteed max price he would pay on capital gains tax assuming he's held the property for more than a year, and then he'd have the money in the clear. His "even if..." scenario is not the worst case scenario for not selling.

You can tradeoff talk latency vs cost yourself easily.

For example, you could have two copies of your data in the block store, and issue reads to both simultaneously, and use whichever returns first. Suddenly, your 99% latency becomes your 99.99% latency...

You can do the same for writes (albeit a bit more complex).
But why not just close the old account? You'll get that short term return for all your checking float in that case.

It depends on the content and the type of updates you make.

As long as I do a significant update to an article, and make sure it's generally up to date and still entirely relevant, then I'll update the date to match.

When people look at the dates (in SERP) they generally want to know if the article is still relevant or if they are likely to find outdated information there. At least that's how I think.

Automatically updating dates without actually revising the content on the other hand... That's not something I'd want to endorse.
Another story about inappropriate emails, luckily I wasn't the perpetrator here.

It was the late 90's. Email systems were generally wide open for exploitation. (It was the golden age of Spam)

I myself had figured out that it was trivial to send a message and make it look like it came from anyone. Simple:

telnet <server> 25
HELO
MAIL FROM: <whatever you want>
RCPT TO: <recipient>
DATA <body contents>
QUIT

I used this a few times to mess with friends, send them messages from God, etc. Good times.

Thing is, I wasn't the only one who'd figured this out, and the university had an "All Users" list with only 3 or 4 people whitelisted to send it messages.

Someone else knew about the forged FROM scheme, and speculated that the "All Users" list didn't do any fancy verification of the "From" address.

This speculation was correct. And the University President was one of those 3 or 4 people whose email address was whitelisted.

The problem for this student was that they thought to themselves, "No, it couldn't be that easy..." And proceeded to send a test message.

It was that easy, and their test message sent successfully. The contents were... explosive. First, it cancelled all classes for the day (of course). Had it stopped there, this story might have ended as just an ultimately harmless prank. But it went further.

The message went on to describe how the president, with this free time from classes, would make herself available to provide, um, carnal knowledge of a very uncomfortable place at a particular time & location.

It didn't take long. IP addresses were statically assigned. It was easy to locate the offending computer, which in this case was in a computer lab.

So, cross reference login times against that IP address, right? Nope, not necessary: The computer was the one reserved only for the lab assistant on duty. Expulsion was rapid. In an interview with the student newspaper, the student decried, "I didn't think it would work!"

I love how this is breaking the mold, paying 3% on checking.

But when you look at it, it's actually not particularly useful. You want to put money in, and take money out right? In this account, you basically can only withdraw money in 3 ways:
1) use their debit card (inc ATM)
2) transfer money out to a bank via their brokerage account
3) have them mail a check (up to $2500 per day)

This excludes all sorts of common use cases:
1) auto pay credit cards
2) link to venmo / other app
3) use other debt cards (e.g., Target)
4) give a check to someone in person
5) make larger payments (e.g., mortgage)
...etc...

My guess is these restrictions are there to protect themselves financially. As they reach a certain mass of users, they may relax and be able to take on more risk.
I wish they weren't black and white, but otherwise they are very interesting to look at.

I sometimes wonder if it is the ubiquity of the phone that allows us to use it as a framework (or that it reveals in some egregious way we cannot ignore) a fundamental social state of modernism that has, in one form or another, been there since its inception. And that we an ignore this because, prior to the contemporary age, there remains so little detailed record if the lives of the, for lack of a better term, masses. Now everyone can comment on youtube videos no matter where they're at in the world or what else they may be doing at the moment. So that we are overwhelmed with our own banality, subsumed beneath a flood of images and messages that we are beginning to feel in some instinctual sense, can never approach in even the most rudimentary of ways, that which we have called communication.

Not quite newly discovered. The plant, camellia ptilophylla, has been studied for at least a couple of decades, e.g. see [1] [2]:

Cocoa tea (Camellia ptilophylla), which belongs to the genus Camellia,
is a naturally decaffeinated tea plant. For many years, it has been
widely consumed by local inhabitants in the Longmen area of Guangdong
Province of China but has only started attracting scientific interest
since 1988.

The tea is also called cocoa tea for the presence of theobromine, the same stuff you find in chocolate, about 10% by weight compared to about 0.35% in green tea.

I love coffee, but have almost completely stopped drinking it. At one point in college, I was drinking around 3 12-cup pots of coffee per day & around 120 oz of coke (I only slept 10 hours total Monday thru Friday). About 2 years ago, I went cold turkey with caffeine. Coffee was exacerbating persistent heartburn. Also, the effect from caffeine was gone, was effectively immune. 20 years of heavy caffeine use...after 2 years mostly clean, I get jitters from a single cup of coffee.
I think it is done for the first time in human history, unless you are thinking about Nazi's children camps in Belarus where they were drawing blood from children to be used for their soldiers (Krasny Bereg- http://mynativebelarus.blogspot.com/2012/04/krasny-bereg-chi...). I'm afraid the dystopian future is here, not in a sense of using certain groups of people for organ harvesting but as in growing humans in labs for that purpose. The Chinese government will most likely prefer the "cleaner" option.
Good point. It does seem like these people just want their "toxic" videos visible and the other side's "toxic" videos censored. At the end of the day, it's all about control and propaganda.

How about hmmdaily and the people who are against "toxic" video just put out interesting videos? Why not compete instead of trying to censor everything?

Also, I've never heard of hmmdaily. If anyone knows what it is and what their agenda is, I'd love to learn more about it.

There is absolutely nothing in the article suggesting that Instacart is developing their own supply chain. They are focused on partnering with retailers to provide this soon-to-be-standard delivery amenity.

They are differentiating themselves from Postmates in this respect. Instacart's positioning is as a trusted partner who won't try to compete with a grocer and eat away at their most profitable categories.

The paper is pointing at one aspect of the modeling (estimating the covariances of the copula), versus another aspect (the copula concept itself). That’s a detail that was very important to the author of the paper, but not to my point.

My point is that mathematical models were indeed being used and followed in this case, and that the issue really was with overextension of the model, and not just generic volatility of any market, as claimed by the GP comment.
How to detect mobile devices in JavaScript
Re: 'Flaw #6: We Still Need a Linter' (first example):

Could the 'primitive' hooks (useState, useEffect, etc) walk up `arguments.callee.caller.arguments.callee.caller...` grabbing function names until you hit a React function? Then use the names to create a 'composed' key automatically? It still doesn't solve the problem of a function using the same hook twice in one function, but it might solve the problem of collision across custom hooks.

Example:

function useCount() {
const [count, setState] = useState(0)
return { count, increment: () => setState(count + 1)};
}

function useCountPlusOne() {
const {count: baseCount, increment} = useCount()
return {count: baseCount + 1, increment}
}

function MyHookComponent() {
const { count, increment } = useCountPlusOne()
return ...
}

Would give you a key of
`useState(useCount(useCountPlusOne(MyHookComponent)))` without the end user having to futz around composing the key manually. At this point you could probably even forego the 'use*' convention

It's still pretty magical, but the magic seems more abstracted. In general I've really liked hooks, and I'm willing to put up with the wackiness (although testing them with enzyme is a big PITA right now).

Thanks for the article :)

Would Google search make more money if they charged 1 cent per search?
I'm finding Prime less and less competitive price-wise than places like Target. When items are directly comparable, the cost of "free" shipping appears to have been figured into the Amazon price.

They're also devaluing it with "this item is Prime, but may take 3-5 days to arrive" and their new in-house delivery, which has resulted in late packages (previously a very rare experience) for me three times in the last month.

I've been an Amazon customer since 1999, Prime since its debut, and this is the first year I've been questioning whether to renew or not.
At work one time, there was a box of quite tasty Lapsang Souchong tea, which had a slight smoky flavor; I drank a few cups of this tea and didn't think too much about it.

Then, on my drive home, it took me a little while to figure out why my mouth tasted like I had been smoking cigars. Something about the smoky-leafy aftertaste confused my brain.
> What you're saying is that cheating is ok, and laws can be ignored.

Huh? All I'm saying is FCC comments don't matter. And therefore neither do fake ones. Not sure what you're referring to...

If the comments matter only because the law requires them, that's a very weak argument.
Most people won't think like that though, especially the millennial target customer who has the time to gamble money, rather than necessarily needing to save for retirement. Currently Robinhood takes three days to transfer funds, so reducing that friction, when customers make impulse decisions when they see that the stock is going up, is paramount. Why wait a few days when the money is already there? This is the benefit of vertical integration.

Qt as an ecosystem is fairly complete for general application development. It includes, among other things, concurrency primitives (QtConcurrent) that are trivial to use*, sockets, database support, serial port drivers and charting (qwt for example). Plus lots of useful tidbits I keep finding like accessing standard system temp directories, making temporary files and adding registry keys (or equivalent).

I've never used GTK in anger, but presumably there's some feature overlap. At times I've used Qt without any GUI components because it's so convenient (nicer than Boost for sure).

It also leverages native GUI frameworks so most applications will blend in with the platform you're writing for (last time I tried GTK this wasn't the default). It's easy to style with CSS if you need it.
Buenos Aires is packed with these protests. I had the same skepticism you had, but my main obstacle is that its such a distant reality that is hardly meaningful to act on.

Somewhat off-topic, but what is the lay definition of "algorithm" these days? From the articles I'm reading I think it's something different to (or at least much more specific than) the technical/CS definition.

People talking about algorithms in newspapers in the abstract are never worried about the class of things that includes ways to tell if a number is even, or which poker hand wins at the showdown. The term as they use it obviously includes recommender systems (maybe only in concrete implementation, though?), but I suspect it might also include navigation in Google Maps. It probably includes chess-playing "AI", but I don't think it includes methods to check that a chess move is legal.

What is required to meet your definition of expert?
You've already collected a nice set of replies, but here's another way of looking at it: Imagine the Earth is a single point mass at its center of mass. Now consider the collection of orbits around it. You still have (to a first approximation) all current orbital possibilities as you know and love them. But now you also have a lot of new orbits. There's orbits just a few inches above the point mass that require nearly the speed of light. There's orbits at what is now ground level. And there are all kinds of elliptical orbits that go through what is now the ground.

All of those orbits represents trajectories in which you are in free fall.

The primary reason these orbits don't "exist" is that they impact the surface of the Earth [1]. However, if you "ride" one of these orbits briefly, you still get the free fall effect, just as if you were in orbit! It's just that you can't stay on the orbit freely because of the minor issue of surface impact.

When you juggle or something, the balls are actually, very briefly, in orbit. Minus air resistance, which is a big deal for a ball. (I initially wrote "throw a baseball", but air resistance becomes a factor very quickly even then.) With a powered projectile, like, say, an airplane, you can deliberately overcome the air resistance for a while and stay in the orbit for longer, even through the atmosphere.

It may seem like a bizarre idea of "powering" through an orbit, but it's perfectly reasonable. It's still a gravitational orbit, it's just that electromagnetic forces (contact forces) are getting involved and mucking up the purity of the orbit, so we cancel them out briefly with other ones via the jet engines. If you had a device that could continue powering through the Earth, you could stay at free-fall even through the rock.

[1]: The secondary reason is that the Earth isn't the aforementioned point mass. A neutrino could hypothetically "orbit" through the Earth for a while before being captured, but its orbit will be complicated by the fact that as it goes below the surface, the "mass" of the Earth starts dropping. Which makes me wonder if there ever are any such neutrinos. The only thing stopping such a thing from existing is the need for a process to create neutrinos that have less than escape velocity for the Earth, and I'm not sure if there is such a process.
I think basically all the sites that facilitated bulk comments are pointless. Can't think of any cases where bulk comments made a difference (outside petitions are a different story, although they're more useful to make obscure issues get noticed by politicians than for changing positions).

But I think portraying this as part of some broad conspiracy is a stretch. In theory the fraudulent ones (as opposed to the merely manipulated ones facilitated by websites giving one side of the issue) could have been placed by one bored teen script kiddy. I agree it should be investigated, but I don't think there's reason to demonize Pai for that.
So it's worth noting that allegations about organ harvesting have been circulating since at least the 2000s. There is likely (almost certainly) credibility in the claims that political prisoners (mostly Falun Gong practitioners) were harvested for organs in the early 2000s. From what I can tell, the tribunal is validating that these abuses occurred.

However, there is not any hard evidence (that I know of - I'd be happy to be corrected) of recent harvesting or coerced organ donation from recent years - in particular, in 2015 China agreed to stop using prisoners as organ sources (https://www.theguardian.com/world/2014/dec/04/china-stop-usi...).

So I'll be curious to hear the final report - whether it mentions recent abuses or not.
That would not have happened because many people who voted for Johnson would have, if he had not been around, voted Republican.
