Missing from the list of videoconferencing tools: Google Meet. Hands-down the best and most reliable tool we've used because it "just works", and is already included in GSuite so there's no extra subscription to deal with. Probably spend at least one hour per day using it and can't remember having any trouble with it, ever.

The app works even in unrealiable network conditions and somehow doesn't skip a beat when switching between wifi and mobile network.

What's the story here? Banks are buying 30-day bonds so they can borrow overnight with the Fed? They can only borrow up to the amount of the bond, so why don't they just... use the money directly rather than in this roundabout fashion.

If the Fed wants to keep the 30-day interest rate down, they can just buy the bonds directly themselves. They don't need to wait for the banks to buy the bonds and then repo them.

This is simply not true. The response of the Merkel administration is one of the slowest and inconsequential in whole Europe.

Yes, you quite often see facepalm solutions.
For example,
In the java world, they cooked up something called 'ant' which was a description in xml that would be parsed and interpreted by a java program to do all kinds of shell stuff (like creating directories, moving files, compiling files, ....).
Obviously, this is a poor man's interpreter, and python would have been a better choice, or probably something like make, or scons, or whatever. I'm not doing java anymore, but I'm pretty sure some people still use it.

Anyway, I've seen people opening sockets in Prolog, and I've seen people doing artificial intelligence in C.

It's not about optimization, but it's surely possible to pick the wrong language for a task.
To add to this, Understanding Money Mechanics (https://mises.org/library/understanding-money-mechanics-0) is a fantastic “comprehensive overview of the theory, history, and practice of money and banking, with a focus on the United States.”

I highly recommend it, especially because it was written recently so it provides understanding behind contemporary banking procedures, practices, and econometrics.
I am from Brazil and while I never heard of Coco with that meaning, "Cuca" is a very known evil character from a very popular series of children's books called "Sítio do Picapau Amarelo"[1], and I would assume that its heavily influenced by the same legend, while in case of the books she is a witch and based more based on a dragon or an alligator than a bugbear. You can see it here from one of the several TV adaptation. [2]

Also, based on the series there is this popular music "A Cuca te pega", or in a free English translation: "The Cuca catch you". [3]

Now we spend a couple of weekends a year in the bush, bringing a plethora of space-age technology just to try and survive: carbon fibre, nylon, and titanium gas cookers that boil water in 30 seconds.

In developed countries, I see no reason why there would be any need for "massive transportation" of either goods or specialists at a scale that would make a significant difference to viral spread.

Even if it were necessary, mitigation measures are neither difficult nor expensive.

Funny, to me the physics of that floating backpack immediately check out on an intuitive level: the less energy I put into making the backpack move, the less energy I'll expend.
In terms of data structures, absolutely. Thing is, for a lot of applications you don't need all those extra features. Lots of apps are boiled down to "The user inputs this, I do some crunching, they get this output." Whether your ints are signed or not doesn't matter because you're only counting from 1 to 100 anyway. One thing it did do very well was to make string manipulation and conversion simple.

Apparently VB does support unsigned data types in some version: https://docs.microsoft.com/en-us/dotnet/visual-basic/program...
Yes, CDC flubbed the test, probably because theirs was a 3 part test. They also ordered that other labs wait for the CDC test instead of making their own. However, any test used had to pass FDA muster at that time, and a test with a 48% false negative rate likely would not.

The CDC is probably not the most agile organization, but I'm hoping that they will scale.

I think you did not understand the point and responded from reflex. Let me simplify it down;

Consumers try to explain that throwing away good devices because the battery is old is bad for the world is not effective enough because it is fighting billions spent in PR that shows you that you need the new device because is slimmer,smarter,cooler and the big companies is doing the best to recycle this products(we send them in China where the smartest of our employees(that are definitely not children) are recycling every atom. So continue buying new things, you don't want your friends thinking you are poor and have the old models don't you?

>, raises a lot of questions about what it means to be human. The relationship between AI and humans is developing and a topic of intense interest, especially among the HN crowd.

We're talking about 2 different things: the importance of the topic vs the the method of exposition.

You're emphasizing the topic's importance. I'm not disagreeing with that. Instead, I'm explaining that the documentary's style of exposition would be a turnoff to a subset of the HN demographic.

As example showing differences in how Battle of Midway can be explained...

Here's the "personality-driven" type of history documentary. Scrub the video and you'll see there's a lot of video showing the narrators walking around the beach and flying in helicopters:

https://www.youtube.com/watch?v=wo9wrUcb8jI

To be fair, some viewers need attractive people talking to the camera to make history "interesting". What does an attractive man walking along the beach have to do with explaining strategy and tactics at Midway?!? Nothing. Maybe some viewers need "eye candy" to go along with their medicine of history. Basically, all of The History Channel is structured as personality-driven type of documentaries with a human-interest angle.

Compare that to another style of delivery with no video of talking heads but has a voice-over with maps and higher information content:

https://www.youtube.com/watch?v=Bd8_vO5zrjo

If HN viewers want the 2nd style of documentary for AlphaGo, this thread's url is not it. The importance of "what it means to be human" is orthogonal to the method of explanation.

For learning I strongly recommend against almost all books mentioned in this thread. They don't really teach how financial systems work in the society or the underlying principles. They give you just a viewpoint. Some of them are good read after you know the basics.

You need to pick up real college textbook (or online course) and read the parts that interest you and skim other parts. Example: Introduction to Finance: Markets, Investments, and Financial Management by Melicher and Norton

You can also pick up introductory undergraduate college textbook in economics and read the parts that interest you. Greg Mankiw's books are good but the price is off the charts, so maybe don't buy them. (Macroeconomics & Financial Systems could be cheap if bought used)

After that some light reading for general audience with interesting viewpoints and lessons:

- A Random Walk Down Wall Street by Malkiel

- Common Sense on Mutual Funds by John Bogle

- The Alchemy of Finance by George Soros (Sorosls theory

China did it to themselves in the first place. They silenced the early warnings about the epidemic, and did not acknowledge anything until it was already too late in Wuhan. It could have ended right there had they been more serious to begin with.

C++: Interviews vs. Fieldwork
This is probably going to get deleted since it's more of a rant than a question, which I formulate here (and remember, cultural thing learned in EE, I never question something without having an answer to it even though possibly just as wrong as the status quo).

Question: what alternatives do we have to the current disfunctional state of both interviews and fieldwork that follows it?
Hint: if I could answer (like actually solve it), that would be worth $B++.

So what interviews ask for:
- Automated tests that ask you to implement a random algorithm with optimum execution and all corner cases handled, within a limit of 30 minutes.
- If you pass the machine gun barrage automated tests, you get an in person interview where they ask you to be an expert in this sort of code: http://aras-p.info/blog/2018/12/28/Modern-C-Lamentations/

Here's a chart made from a study in China. It's actually a bit unclear, but I'm assuming it's 18.5% of confirmed cases that require hospitalization. Now, the question is how many of those that got sick at all got confirmed in China, and how many people presented symptoms (those are unknown).

So it seems like it's less than 18.5%. On top of this, Chinese men are heavy smokers and the air quality in China is pretty terrible, so that may play a part as well.
This behavior? https://devblogs.microsoft.com/powershell/suppressing-return...

It seems like it might make some kind of sense, since it doesn't output directly to the console but rather to a pipe. Bash functions sort of work the same way since they don't have complex return values (aside from exit codes) other than the function's output stream.
What fieldwork consists of:

1) No abominations like above, which by the way does this:

void printNTriples(int n)
{
int i = 0;
for (int z = 1; ; ++z)
for (int x = 1; x <= z; ++x)
for (int y = x; y <= z; ++y)
if (xx + yy == zz) {
printf("%d, %d, %d\n", x, y, z);
if (++i == n)
return;
}
}

To my experience, any team and project manager that's incompetent enough to allow for such "genius" to unfold themselves in a production and comercially bound project, well they get slaughtered. I haven't yet seen companies incompetent enough to do that but I've seen projects spanning over the course of 3-5 years with dozens of people involved being tossed away and the geniuses (and company) be supported by the humble C level of "mediocrity" of the printNTriples.

2) There are hard algorithms to be implemented and they usually involve hard and horrible domain knowledge that takes a heck lot of effort to aquire, effort of which as wishful you may be you'll never be able to factor out time and lots of it, is plain nasty and entirely non-portable outside of the environment that never pays you enough for dealing with it. Ex: for those who complain on "no documentation", the domain knowledge of the domain last amateur level project yet $500M worth commercially project that I worked on could be described in maybe 5 pages of documentation, the contract we work on that's worth some $5B has 1111 pages of documentation in some 20 chapters and my assigned one leads to some 20 other documents amounting to more complexity.

All the while the greatest challange, in C++21 still remains to compile the damn thing. Not that it takes 2 hours to compile what in Java essentially it's Borland's Pascal 5.0 responsiveness (latency and throughput). We've learned to be so traumatized by C++ that as long as it compiles*, we're happy.

Not to mention BUILDING the damn system, like setting it up for first time use, with dependencies and all. Everytime I change projects, I cringe and pray from a miracle from God if the process takes less than one week. Not that I complain about that week - see above.
