I don't see how Levels 4 and 5 can happen without a massive civil engineering effort on the road design and construction side of the equation. Everyone talks about the work being done on the cars. What about an effort to better standardize the roads, markings, maintenance, etc.? Until that happens, we will never get there IMO.
If this was a new strand of the flu then I could understand what you are saying, but now we will have the flu which as you said many people die from, and we will have a new virus (nobody has immunity to) which many people will die as well, especially once this virus fully spreads across the globe.

Now I don't think extreme panic is a good, but fear on a certain level could help. I am in a major city and I have seen a lot better hygiene practices from civilians and businesses in the last couple of weeks.
Malnutrition was a major factor yes, but not to an overwhelming degree. For example dental issues were also a major problem, and of course nutrition itself is a health issue in which a well functioning health care system plays an important role.

The same way you ask me to do a "minimal amount of research", you should do the same to answer the question about what is a systems programming language.

Claiming "within ~3x of C++" answers your question. For the problems I work in (some of which you mention) even a 5% is a major deal. 300%? That’s just crazy talk and a non-starter.

That’s what performance means and why most language benchmarks are usually useless: people writing them have no clue of what are the requirements of many fields.
And for me what I really appreciate is that he accomplished it in a way that is humane and self-sustaining. I've had young friends work for TJs, and it seems like it's a much better employee experience than equivalent places. It's certainly a better customer experience.

Somehow this culture has survived for decades, despite short-term thinking and too-narrow optimization destroying the staff and retail experience at other grocery stores. I'd be enormously proud to have achieved something that lasted like that. I wish I knew how they did it!

I get similar satisfaction from a "putting things together from the basics" perspective. And now that I'm no longer in the industry, I put most of my limited "crafting" time into using and exploring old things like awk, make, C and bash, the things I started with decades ago.

I do regret deleting my github account, but I just don't have time to respond to much-appreciated PRs.

Pangolin – An Enhanced Horizontal Pod Autoscaler for Kubernetes
Well, the reason I say this is I caught seasonal flu in the fall, a few months before the coronavirus was discovered in China. It was one of the worst flus I have faced. It was a very body-achy kind of flu, which afaik is not a covid symptom.
For #1, it really depends on what you mean by "array" and what you need to use it for. Sounds like an XY problem.

If you take it to mean a more abstract concept of a list of things that can be iterated and accessed by index, then the fastest implementation is O(1): build no data structure at all - just implement the iterator and index functions.

If you take it to mean physically manipulating atoms on a chip to be in a certain state, then you'll actually have to do something :)

Weathervane 2.0: An Application-Level Performance Benchmark for Kubernetes
Number of cases reported is partly function of tests performed.

US has tested something like 500 people and CDC can test only 400-500 samples per day, UK has tested over 7000 people already, Italy almost 10k, South Korea tests 10k per day and plans to increase it to 20k per day.

Nonsymptomatic people or people just mild flu symptoms will go on in the US infecting others.

Masks are considered useless unless you are infected.

This is a bizarre claim that can be countered against the reality that every front-line worker is equipped with a mask.

EDIT: Almost immediately I dropped to -2. Bizarre. Again, every health agency the world over equips health workers who deal with potential COVID-19 with N95+ masks. For some reason people desperately want to clutch onto the notion that it's useless because otherwise..uncomfortable and uncool mask, right? Another poster mentioned that the source didn't even state that about masks, but instead about surgical masks which is a tiny subset.

-Masks prevent aerosolized matter (e.g. a sneeze) from getting at mucous membranes (where it needs to get to yield an infection).

-Masks prevent you from touching your hands to the vulnerable areas of your face. It is effectively a check. So when you touch that door handle leaving the subway station it's far less likely you'll transfer to your mouth or nose, and we naturally touch our face thousands of times a day. Ideally one would have a mental process they follow where you clean thoroughly before taking it off.

Those alone seem like an absolutely enormous win for masks.

https://time.com/5785223/medical-masks-coronavirus-covid-19/

https://www.livescience.com/respirators-prevent-coronavirus-...

I'm certainly not at the point where I'm going to wear a mask in public, but the whole "Hurrr masks don't work at all" seems like either disinformation (e.g. stop buying all the masks because we want them), or people trying to comfort themselves in some bizarre way. Every bit of evidence says otherwise.

The moderation through this is absolutely cartoonish and ignorant.
Exactly, an apology!
It almost sounds like the goal was to find something that a candidate doesn't know. How about finding the things the candidate knows and basing the further discussion on top of that.

All this obsession with coding tricks in the interviews is just awful.
Sure, every set of vectors will span the space they span. But the requirement that a basis span the space refers to the space it’s in, not the space it spans (otherwise every linearly independent set of vectors were a basis, spanning the space it spans.) I could go on :-)
Unfortunately you have failed this regular programming challenge.

How to Optimize I/O Intensive Containers on Kubernetes
Governments have other concerns besides your individual health. They need to prevent panic as much as possible, prevent economic collapse, etc. The response to events like this can be worse than the initial problem.

What do you think happens if the CDC says everyone needs to wear masks, you go to your local store, and there are no masks? There would be violence in the streets.
Here's a summary about this technological renaissance of knowledge sharing:

- Roam Research: note taking using bidirectional links: https://www.youtube.com/watch?v=v9s3pusI1JQ

- Substack: monetizing email newsletters

- Static websites: high-performance, low-cost blogs when compared to WordPress

- Threaded Twitter: aggregating and collecting long threaded tweets as writers are using Twitter as a micro-blogging platform

- Ebooks: better than printed books

- "Blogging is Dead, Long Live Blogging"
These sorts of books have existed since the dawn of notebooks. While I think them useful for demonstrations, I don’t think there is much pedantic value (beyond a more static medium) in all honesty. Well-worked examples a student can consult while attempting to solve problems on their own is still of paramount importance.
This doesn't look like an improvement - I'd feel even more closed in with this configuration.

If you're in a bottom seat, you've got someone's, well, bottom, right in your face - not a very appealing prospect.

They also don't recline, which will make sleeping impossible or very difficult on long haul flights.

I also wonder about this from a safety perspective in the even of an evacuation - I imagine you'd have panicked passengers in the top seats jumping down onto those below.

And finally, even if these seats have a bigger pitch (more leg room) as a concept, airlines will simply cram more in, while keeping the same, horrible pitch of 30-32". That's not a problem with any particular design, of course, but it's what any airline is unfortunately going to do.

Why East Germans are not taking advantage of the large wage gap
If I lend you my megaphone, should I be held responsible if you use it to say something illegal?
You may be correct, but I'm just throwing out the idea that perhaps, the needs of these two different kinds of companies are so different that it is a good idea to specialize in one or the other, else you become mediocre at serving either one?

But the flaw in my logic is that the one, sometimes evolves into the other.
I wasn’t condescending until you were. I initially questioned your claims, and you responded by asserting that you were correct and I was not because you are a medical student and I am not. It had nothing to do with the validity of what I was saying, it was an appeal to your own authority. If you do not wish to make an argument personal, then you should refrain from using your person as an argument.

Secondly, it isn’t the only data we have. The data in the sources you linked are dated. There has been weeks worth of data and tens of thousands of cases since January 2nd, so to rely on papers focusing on 40 cases from 2 months ago is inexplicable. And even our current estimates of the death rate are still very likely over estimated for the same reason: sampling bias. It appears that it takes longer to recover than it does to die from this disease, and so deaths / (deaths+resolved) will be biased high. It also fails to consider that mild cases are less likely to be detected and therefore won’t be included in the calculation, further skewing the death rate higher. And lastly, the overwhelming number of cases so far have been from a single province in China, overwhelming their capacity. Outside of that province, the death rate is far less. That isn’t to say that other provinces/nations can’t also become overwhelmed, but there is something to be said for the fact that having several months of preparation and notice will improve readiness remarkably compared to Hubei province, which only was able to react to the outbreak after it had been occurring for several weeks.

This is all to say that, yes the virus is concerning, and yes people should prepare themselves, but it is also incredibly irresponsible and dangerous to spread immaculate and misleading information based on long outdated studies and statistical malpractice, and then do further damage by stamping it with unearned medical expertise.
Lamenting tent cities is "old man yelling at cloud" to you? I agree with his points. The Life of an average person is objectively much worse than it was 20-30 years ago. A person with great discipline can have a better life than ever, but it is hard not to feel empathy for the masses, so addicted to fake internet shit that they cannot even distinguish reality.
Is this even a bad thing?

The users of this software are "professional" - they interact with it anywhere from dozens of times a day to literally their entire shift. As such, the primary UX concerns are going to be speed and accuracy. Though having lots of buttons doesn't fit the slick/minimalist styling a lot of current apps go for, it's undoubtedly faster to use and easier to learn.

I'd expect the most common operations to take 1 or 2 interactions (presses), and the least common shouldn't take more than 3 or 4. It should also be easily discoverable, From just looking at the screenshot, and having almost no experience with PoS, I'm pretty confident I could use it immediately with no training and actually place an order for someone.

That said, Aloha in particular could probably benefit from some tweaking by a graphic designer - even just some minor changes to the color palette, spacing and border styles could make it much more visually appealing, without losing the current UX.
I would like to agree with you. However, your vision hinges on this massive invisible infrastructure which is the cloud.

Your phone didn't recognize the object, you relied on a cloud service to do that for you.

When you use such services for free, you'll end up with all kinds of legal compromises that don't necessarily benefit you as an individual in the long run. Your personal convenience is subservient to other goals that don't necessarily align with public interests at large.

You could argue that the infrastructure will keep miniaturizing and one day you might not need those services. But that's not how things are currently evolving. Moreover, it will always take massive amounts of data to re-create the same models that are able to recognize patterns that are relevant to your specific context when you have a query.

At the end of the day, it's about what trade offs you are willing to accept. Cloud services based on machine learning do give you a good amount of convenience, but then you have to be willing to accept the hidden costs as well.
Yeah, ok, though I'm not sure what that will prove. As I said, it's really just a case of writing a backtracking recursive thing. Here it is in prolog:

letter(a, X) :- string_to_list("._", X).
letter(b, X) :- string_to_list("_...", X).
/* rest ommitted for brevity */
letter(z, X) :- string_to_list("__..", X).

morse([], []).
morse(Morse, [Letter|Rest]) :-
letter(Letter, Head),
append(Head, Tail, Morse),
morse(Tail, Rest).

Prolog is obviously excellent for this kind of thing since the backtracking comes built in, but it's not massively more complicated in other languages.

For "_.._", it gives you the following answers (I added some line-breaks):

?- string_to_list("_.._", L),
findall(English, morse(L, English), Answers).
L = [95, 46, 46, 95],
Answers = [[d, t],
[n, a],
[n, e, t],
[t, e, a],
[t, e, e, t],
[t, i, t],
[t, u],
[x]].

I wasn't saying that it's not a good little problem. It's a lovely little problem, which you solve with recursive back-tracking! I wouldn't say it's a "trick question" though, it's just a regular programming challenge.

EDIT: Oh, I see what you're saying, do you mean "It's a trick question because there isn't necessarily just one answer"?

If so, then I misunderstood, I figured the challenge was "find all valid interpretations" of a certain morse code string. The fact that there could be more than one seemed fairly obvious to me.

You can look at such imperfections from another angle.

Think about it, you don't like the product because of issues you've described. You're still using it. Maybe, M$ got the product right on the parts you're really care about? Like office integration, price and so on.

Messengers is a very competitive space: slack, m$ teams, zulip, mattermost, skype, telegram and so on and so on.

My point here is issues you described just minor inconvenience and they wouldn't bring much value.
The sheer contagiousness of COVID19 means that any quarantine measures would only slow down, but not stop the spread. If they stamped it out in SK this month, in a few months it would be back. Most health experts believe it's inevitable it spreads around the globe.
It’s similar, but in this case the decision is removed as it is given that a solution exists.

I asked for your help. Why did you see fit to get rude? What the hell is wrong with society that people like you think this is okay? Toxic responses like this ruin tech because instead of teaching you attack.

Loads of research suggests 7 year olds are about 70% accurate at predicting gender based off of pictures. It takes a couple of decades to get that into ranges you’ve cited. That doesn’t sound easy. If it is, I’d love to read about it.

Overall though violent crime is down nationally. That said my partner was robbed, pistol whipped, wrongly accused by the cops of being the robber, and then spent months recovering from a pistol-whip induced concussion. So yeah, sometimes a simple street robbery can take some time to resolve.
Yes, but I don't see this as a good reason to drop all fast but not cryptogaphycally secure prng from which simulations can gain an advantage. Every exising tool can be misused, not providing the tool at all is an extreme measure that in this specific case I think wouldn't even solve the problem: if a programmer does the mistake to use a non crypto secure prng for cryptography is very likely that he will also do other mistakes like reusing nonces or leaking memory or other less trivial errors.
What I think is important is whenever somebody proposes a new prng to clearly state if it's cryptograpycally secure or not.
Right. But I often see people ask "how can I learn to X" and get advice like "Go do Y. It will force you to X". But jumping into to the situation unprepared is not how pilots learn skill X. They learn it through particular methods of study and practice.
Alas, iOS only!
I use it for a fairly simple task and I often run in to compiler bugs. Const buffers over 64k get truncated on NVidia gpus, using half4 broke the optimizer on some iMac gpus, and sometimes I have to split up functions until the optimizer on some gpu I don’t own stops doing crazy things.

I wonder if the $$ emphasis is the wrong way to look at this list. I'm wondering about:
- time to train on how to use it * every employee you ever get (some of them it's trivial, others not so much)
- time to do security reviews of any of them where sensitive information might ever pass through it (which is most of them)
- the risk of lock-in to something that gets bought by a competitor, turned into adware, or acquihired and shut down (in some cases switching is trivial, in others not so much without losing a lot of valuable history)
I've never really been worried about disease outbreaks in the past but this is different.

> she's got 25+ years of experience working on the front lines specializing in responding to disease outbreaks like this. She literally writes the policies and training material for professionals in this area.

This isn't the right set of qualifications when it comes to understanding the total impact. Aside from the front line staff often not having a high-level understanding of epidemiology, I also don't think she understands the economic costs of containment.

Early on, there was a huge amount of complacency because we've been successful in the past and nothing like this ever came to pass. Expertise in some narrow field can only go so far - unless they are familiar with this particular case, how different it is from other pathogens they have experience and sufficiently mathematically inclined to be able to extrapolate beyond the existing data. We have a once-in-a-life type of pathogen IMO and 25-years of experience may not matter much if they are merely looking back in their experience to find similar situations.

> She's absolutely livid at the way the media and politicians are dealing with this. The CDC and WHO are being forced to respond the way they are because of the political and social pressure. They're trying to keep people from panicking but they just get accused of trying to cover up 'the truth' if they try to downplay the media driven frenzy.

How people tend to respond to events like this is part of the reality of the situation. You can't simply hand-wave away the social, political and economic consequences of the expected responses and how that affects the disease-fighting efforts.

This reminds me of the financial crisis - if you did a top-down analysis, it pointed to an unprecedented situation and it was easy to see how the market actors would response in a way that would compound the crisis but but most experts had never seen something like this, didn't have a comprehensive understanding of how things work, had never seen true panic and had some flawed models telling them that in some perfect world, things are fine and some of the earlier market movements were irrational overreactions.

It depends on the kind of care you can get. With early detection and ample care it is likely 1% or lower. Chance for serious pneumonia (meaning having oxygen issues) is around 14% for the current mix of patients. In an overwhelmed medical system mortality rate will be higher than even what Wuhan experienced.

You don’t need sfinae to get Turing completeness of templates. Template specialization (a crude form of pattern matching) is the main driver for Turing completeness.
