Having visited the Amazon Go stores in Seattle at-least 30 times over the last couple of years, including the newly opened Amazon Go Grocery store, I can confidently say that the technology works quite well for the typical shopper.

I agree, the question of, can this technology be integrated into existing retail spaces and still work well enough to be economically viable is important. But considering that there hasn't been any other retailer who's come up with a competing product over the last two years, tells me that Amazon could be way ahead of the competition on "Just Walk Out", and possibly dominate this space of retail automation for a while.

That article is an absolutely fantastic example of how the press treated BlackBerry (average consumers might come away thinking that BlackBerry devices are insecure).

It is after BlackBerry was dead from a market share perspective, so this isn't really applicable to the period I am referring to, which was from iPhone launch to maybe as late as 2012, when BlackBerry went from hero to zero.
fair enough, but why would that be worth a million? Even using the phrase in a jocular fashion - it's not that interesting of a photo.

Being pedantic if I look at his photos on Getty Images and choose something about the same quality (I didn't find the exact image) and selecting for both web and print newspaper editorial front page I'm thinking about $4000

Is it actually a million on Getty Images? Or is it worth a million as in the common vernacular usage because it is amusing or has some worthwhile quality I cannot discern?

I do not understand what Russia has to do with this?
If you claim that there are more people traveling between China and Italy because some commercial interests why not say that? I have no idea about such people traveling but from what I see as an outsider a lot of US business people are traveling to China and Taiwan too.
The doubling rate is 3 days. Either we will be in a 3 month long quarantine, or in three months the infection rate will be slowing because there's no one left to infect.
Also, what would the mechanism be? Coughing is the ‘normal’ mechanism to move viruses out of your lungs.

If it spreads before the coughing starts, i.e. during normal breathing, doesn’t it get out of your body too easily?
> markets are about price discovery

Exactly, and when you have an unorderly market, price discovery becomes problematic.

It’s the same reason the single stock LULD bands exist (which put the brakes on both rapid downward and rapid upward movement). Stopping for 15 minutes (or 5 in the case of a LULD pause) is not detrimental to the process of establishing orderly price discovery.

In the event a stock is going to keep rising or falling due to legitimate changes in valuation it will continue to do so (look at NASDAQ’s halts page today to see stocks that have hit their bands multiple times).
Per the article:

He saw his PCP same day, they examined him, but said he should go to the ER.

He called the CoronaVirus hotline, which also said he should go to the ER.
$2.99 at 6.5% tax is $3.18 (after rounding). Buy two and your total cost is $3.37. The government don't not want to be cheated out of that penny. (it adds up over all the people buying stuff)
Yep, that is due to order flow from retail investors. They always put their orders in at the open (that is why Mondays can be risky) or at the close.

You can see this by looking at the difference between the return on stocks in the first/last hour against the return over the rest of the day. I have no idea if this effect still exists today but you used to be able to print money from this (and I am sure it still works in places like China with lots of retail investors).

Does Savvy provide plans with Health Savings Accounts?
This is a lot different though. Banks were the actual dealers of the securities in the big short- you were actually buying and selling to the bank itself. Robinhood and stock brokers, you aren't buying and selling to them- their primary function is to just give you access to the markets where market makers are participating on the other side of the deal. Robinhood does not participate in market making, they purely give you access to them.

In the Big Short case, the banks were acting as market makers, or more technically in this case dealers- this was more akin to going to a used car lot. You read a lot of reports saying that the new Fords were flying off the lots for outrageous prices, and to people with dubious ability to pay for the sticker prices they did because they got loans they shouldn't have. You go to the dealer and say I want to sell these cars short and buy them back later. The dealer presumably thinks you are an idiot, or wants to hedge some risk (the analogy is breaking down here), but says ok sure, thinking he is going to sell them for even more in 6 months. 6 months later comes- you were right- there is a flood of Fords on the market at half the price because so many people had them repossessed or are desperately trying to get out of these loans that are killing them. You go to the dealer and say "Ok bud, I'd like to buy these cars back at half price..." and they say "Nah, these are still worth 98% of what you sold for... how about that price?" and you are kind of stuck. You bought specific used cars that are kind of but not really entirely fungible. You can't just go down the street and buy those cars and replace them. You have to hope that they feel the pressure to lower those prices because they start feeling the squeeze for cash, or a regulatory agency comes in and puts the pressure on. They can kind of live in la-la land and avoid the reality of the situation as long as they have no requirement to sell.

Eventually though, they blinked and once one bank started taking write downs, all banks did, and once that became acceptable, they all followed suit- and they also needed the cash at that point.

Anyway- now back to stocks/options- these have well known discoverable prices and you can sell them on open markets where the brokers you connect to might be on the other end of the deal but its really unlikely. A broker/dealer like Robinhood or Schwab or Interactive Brokers should theoretically have an entirely flat position at the end of the day.

TL,DR: Robinhood didn't go down because it doesn't want you to sell your stocks.

A recession isn't probable, it's inevitable. It's just a matter of how much sludge builds up in the economy before the over-leveraged have to unwind. That's the business cycle.

Covid19 and the ensuing fall in global demand is simply another blob on the pile.

Games are quite small -- under 50 turns, each under 2 bytes in binary, but more if you start with simple text languge before compression. You need to compress each game individually. Would database-wide compression work?
The "Testability" example also seems to have a typo in the definition of describe. Specifically the first error case, it uses the constructor Odd, when Even is the one defined (and the error case itself).

> "harmonises" in the sense that it takes one of the most common programming symbols and changes it? I don't know of anyone that sees "2 & 3 = 2" and thinks "yeah this makes sense".

There are a few of us in this thread, trying to explain why.

You find outrageous that 2&3=2, almost everyone (all the non-programmers of the world) will find more outrageous that i=i+1. You get used to it quite fast. It's obvious as soon as you realize that, with booleans, min is and, and max is or.
Recessions happen every 4 to 7 years. We haven't had one for 11 years.

"The Lombardy outbreak came to light when a 38-year-old Italian tested positive in Codogno, a comune in the province of Lodi. According to his wife, he had met an Italian friend who had returned from China on 21 January, who subsequently tested negative.[20] On 14 February, he felt unwell and went to a doctor in Castiglione d'Adda. He was prescribed treatments for influenza.[20]

On 16 February, as the 38-year-old man's condition worsened, he went to Codogno Hospital, reporting respiratory problems.[20] Initially, there was no suspicion of COVID-19, so no additional precautionary measures were taken, and the virus was able to infect other patients and health workers.[21] Later, the patient, his pregnant wife, and a friend tested positive.[20] Three more cases were confirmed on the same day, after the patients reported symptoms of pneumonia.[22] Thereafter, extensive screenings and checks were performed on everyone that had possibly been in contact or near the infected subjects.[23]

The 38-year-old man was asymptomatic for weeks, reportedly led an active social life, and potentially interacted with dozens of people before spreading the virus at Codogno Hospital.[20][21] Afterwards, he was transferred to Policlinico San Matteo in Pavia,[24] and his wife to Sacco Hospital in Milan.[25][26] " [1]

This is hands-down the most cringeworthy comment I've ever seen on HN.
According to Wikipedia[0], which in turn sources material from January (mostly China), each infected person infected 2.2-3.9 others on average. So in three generations you go from 1 to 27. Three generations more, from 27 to 729 (if my math is correct).

Oh bullshit, come on! How can a couple photo-ops and the promise to work out some favorable trade deal in the future got to do with a disease spreading today?!

What happened is that someone in Germany got infected and spread it to Italy via open Schengen borders (ironically, everyone was looking at the leaky direct flight bans with China)

Poor protocol in a couple ER waiting rooms caused superclusters and now it’s spreading endemically.

Stop that factious blabber, please
The ease of updating Ember apps is really great. I've helped take apps through the early 2.x to latest 3.x. There has been some tedious work involved, but on the whole, I usually know exactly what to do to get the new features. Not breaking existing features is a godsend, because the rest of the team can keep developing features and we can introduce new features via lint rules at a reasonable pace.

It appears that it may be coming under control in South Korea actually. We need a few more days to be sure. It also appears to be under control in China as well, with less than 100 new cases reported there yesterday.

Containment in an absolute sense is not possible, but the data does not support a conclusion that pervasive infection (e.g. 10% of world population, as what happens every year with the flu) is inevitable.

Arguably the only two data points we have at this point seem to point to containment actually being possible.

Only once the daily testing rate has stabilized can you directly observe the new case growth rate without a bias.

My theory on the severe case load in China is that the total infection rate is under-reported by at least an order of magnitude. We’ll only ever know if we have reliable serological testing (for antibodies) which is not yet being done.
There are, of course, tradeoffs to using defunctionalization (I've also heard this called a "data DSL"). I have seen these tradeoffs often ignored or argued past when discussing various solutions that take advantage of it.

The cons to defunctionalization that I have experienced are things like:

You now not only need to test your application, but also the runtime that turns this data representation into actual work. Bugs can now occur in the runtime, in the reification of the app logic, or in the integration between the two.

If your application is particularly concurrent or lazy, then ensuring that your DSL works well with your main language's concurrency and laziness machinery can get pretty hairy when you start executing your side effects.

It becomes harder to leverage your languages developer tools; breakpoints and debugging often end up in your DSL runtime's code, not your application code, often requiring special-purpose tools to be built to debug your defunctionalized DSL.

Performance can also be a double-edged sword. On the one hand, you can do some very clever things; use tricks like memoization, all the way up to writing a JIT compiler for your defunctionalized DSL to improve performance. However, you're taking on that work due to the fact that your main language's runtime can no longer do that work for you. Often these data DSLs end up allocating a lot of data structures that end up being parsed and thrown away later, and those allocations increase work in cleanup and the parsing itself.

I also heavily question the efficacy of testing these data DSLs. It is objectively easier to test pure functions, but on the other hand, how do you validate that they are correct? Often we don't care about the actual data representation, we care that it does the work it describes; properly testing then essentially becomes a re-implementation of the DSL runtime with mocks / etc.

For a concrete example of all of these tradeoffs, take a look at React in the webdev world. React is unequivocally a good idea, but it has required a massive investment from the React team and the ecosystem to make it correct, make it fast enough, to create developer tools for it, and to figure out how to effectively test applications that use it.
No Dumb Interviews – Rank Tech Companies by Their Interview Process
If anything that'll prop up stock prices further. We were about to hit a demographic time bomb in the mid-2020s as the baby boomers started to retire and need to sell their 401(k)s to live on and afford medical treatment. If they all die suddenly, then their assets get passed on to their prime-working-age children, who have no need to cash them out. More savings finding their way into a dwindling supply of available stock = higher stock prices.

That's a few years off, though. During the crisis itself, when nobody knows whether they'll live or die or what sort of interventions they need stay alive, I expect to see massive panic selling.
I don't know if there is such confidence among specialists, but among non specialists the arguments I have heard are based on assumed similarities with the common flu. These arguments may or may not apply , and there is still disagreement and unanswered questions on why the flu is seasonal:

I wonder if there's a good way to distinguish different B2B businesses that are more or less effected.

For instance, my dad used to be a mechanical engineer designing large construction equipment. Maybe 10% of equipment was replaced a year, so if there was a demand for 10% more equipment one year then they'd have 2x sales. But if there was a 10% decline in demand, then they'd have 0 sales, the broken equipment was acceptable attrition.

So... that industry really sucked. But if the businesses have to pay for your services just to keep running, then it won't be too bad. So server sales might go up and down a lot, but AWS demand will be much smoother.
The core belief of Americans and the defining belief in my opinion is you can rise to any level of success or failure based off your own efforts alone. I’m not arguing the validity of belief but I am arguing against whatever idea you have of gods will and America’s founding.

Americans will have less sympathy for the victims of the virus but not because of gods will blaming but because they’ll blame that person for touching their face or not taking precautions. We blame people for failing not god.
For me it's the following:

I want to improve my APL(Dyalog/co-dfns), Rust, and Coq skills to passible levels, i.e. being able to comfortably use them and writing code in an idiomatic style.

I also want to improve my skill with SystemVerilog and VHDL. I'm decent with HDLs but I need a lot of work with regard to my testbench writing, translating specs to a TB, and using the random constraints based testing(similar to property based testing in the SW world).

I'm trying to properly pick up C++ template meta-programming and improve my familiarity with minimal to zero cost abstractions w.r.t FP and HOF.

Outside of programming skills, I want to start learning some project management skills, i.e. feature breakdowns, timeline estimation, and the basics of when/how to pivot.

Finally, I'm trying to learn how to tell when I start falling into one of my biggest issue as a developer and how to curb it: getting stuck on an idea and overlooking better alternatives.

It's a bit to take on but I'm young and don't have too many commitments so I figured it shouldn't be too unachievable.
Not a major role in Wild Strawberries, though? Agree with you nonetheless!
Please don't descend into name-calling.

What PeCaN said there is no different from what masters like Chuck Moore and Arthur Whitney say.

No, the author is suggesting that you work on projects that are intrinsically motivating, i.e. things that you would want as opposed to problems other people want you to solve.
Of course, but those predictions are only based on available information. We probably won’t know which companies will be worst affected, or where. There’s no way anyone could have predicted Lombardy would be the first part of Europe to be hit so hard. When particular companies, regions and industries turn out to be more severely affected, they will take the hit asymmetrically, but that will hurt the overall market. The current impact us being gauged fairly tentatively IMHO.

For example it’s likely several more airlines will go to the wall, but we don’t know which ones yet.

I really want to like you for taking a stab at solving this problem because it's a serious one for startups and small businesses, but I can't as long as you keep this approach. Shopping for insurance (even through a broker) is an extra layer of friction to the hiring/onboarding process and this needs to be removed.

In my experience, startups are bottlenecked by hiring more than anything today, and part of that is compensation/benefits. If you make it more difficult or more complex for startups to get people compensated and set up with benefits, they will decide to work somewhere else.

Snapping up gold in what I see as the inevitable return of inflation.

The US is aggressively deficit spending in the boom times and in order to keep up this unsustainable spending in the bust times, the gov't will have no choice but to juice inflation.
The Japanese stock market is so completely different from the West - you can draw no applicable conclusions.
According to the data, it's closer to 1 week in the US. The pandemic curve latency is roughly 45 days between China and the first cases in the US. Also, the US is large and the pandemic will take more time to accelerate (or not at all) in far-off places than urban areas... it won't spread uniformly or coherently.

>because many designers -- often instructed by their customers -- continued to think in terms of layout inseparable from their visual design.

Because layout (space between elements) is inseparable from visual design, it's what has the biggest impact on visual perception right after contrast (visibility). Doesn't matter if web or analog design, it's a law of nature.

Because those are the standard terms of intellectual discussion. People going into such a conversation without an open mind are called idiots, and they're not worth taking too seriously.

Isn't it weird that people don't value that?

I mean, look at how many python programmers are out there! I have programs written just five years old that don't work in a new python interpreter and that's terrible for "longevity and sustainability". Good thing there are so many cheap Python programmers so we can keep the costs down: We're going to be rewriting this thing until we're old and gray!

I personally find this line of thinking quite unproductive though.

There are plans that are exempt from ACA's "requirements" because of course there are, and the current administration has used its rules-making powers to expand such exemptions. These are not limited to backwater states with evil administrations. At this very moment there are plans on California's ACA market that are exempt and do not cover maternity.
