As others have commented above, reducing the rate of spread (social distancing and hygiene, and convincing others to do likewise) so that this is a more smeared out event with a lower peak need for equipment and staff is the most important intervention. It's also very hard to do; not sure if there is a technological lever that will move the needle on this (advertising?)
I'm remote and definitely don't. I sort of understand the idea of being responsive others have articulated but IMO it's never that important. It's also trivial to add when the need (business trips and on call) arises.
Just flew over the article, but it made me wonder: When I'm developing scripts for our workflow systems I'm often also "logging" successful events. It helps with looking how a process works but in the end I never remove that logging output.

I wonder how you people handle that. Do you also log "good events", for example when nothing happened just to be able to see everything went well?
Attempting to turn this more constructive: How would you define "actual" progress?

None of the results linked above are immediate disease cures, but that's normal. Most research is an unsexy sequence of small increments of progress.
How Netflix uses Druid for realtime insights
Having walked over 4000 miles in a Deuter backpack that weighted on average about 33lbs/15kg, I would just add that while optimizing backpack fit is absolutely important, it is more important to constantly optimize how much weight you are carrying. The latter is way more an art than the former.
Most of the modern backpacks portrayed are heavy and designed for 45+lb loads (of which some of these packs will comprise 3+lbs).

Would have liked to see more ultralight representation because it serves as a good counterpoint to all the tech that though effective, adds weight.

Reducing weight has been the biggest advancement in ergonomics for me. A pack is an important part of that total and many of his examples - ladder back adjustment systems, contouring supported by robust plastic and foam, articulating ball joints - add to it.

You Ain’t Gonna Need It - unless you don’t apply that attitude and end up with a 75lb(!) bag.
Sure, but you wouldn't have any new viruses if you weren't a bioweapons lab.

Show HN: Simple Testing Framework for C/C++ on Unix
I get bored by more esoteric statistics terms in epidemiology, but accuracy has a simple enough mathematical formula: https://www.lexjansen.com/nesug/nesug10/hl/hl07.pdf

(True positives + True Negatives) / number of all tested

Similar concept comes up in measuring accuracy of computerized image segmentation, where you ignore the true negatives

true positive / (true positive + false positive + false negative)

where it is called intersection over Union (IOU).

I can’t ever remember the names, and just rebuild whatever metric I care about in terms of true vs false and positive vs negative.

Applying all this to the real world is tough because of the over fitting problem. Even if you got the test to be 100% accurate in your tested population, it doesn’t mean it won’t be wrong on the next person it tests. Generalization is hard. So doctors have to guess based on their understanding of the tested and untested population and the sensitivity and specificity of the test. You can go meta and give the doctor a sensitivity and specificity also.

The BS was for you to claim the each mask has to be inspected. I am pretty sure that if the US will have agreed to accept the gift (fat chance I think) they would have some of those checked.

... which is why no system ever implements things this way. There are many portions of the C spec that can be ignored.

Large swaths of the C standard were built during the heyday of computer design, when you had all sorts of wacky sizes, behaviors and abstractions. Lots of "undefined behavior" is effectively deterministic, because all modern computers have converged to do so many things the same way.

Here's how I see the current market correction and virus situation as compared to the dot com crash of 2002.

Markets were over priced in both cases. During the dot com it was much crazier and prices crashed a lot. This time its not so crazy, so stock prices may come down less.

During the dot com burst, the 911 disaster weighed heavily on psychology. Now it is the virus.

In both situations real estate prices in tech areas were crazy. This time the prices are even higher. So more of a price drop in real estate?

A lot of tech people lost their jobs in the dot com burst. This time somewhat less?

So, the way I see it, we have a lot more down side for a lot longer to go - basically agreeing with the article.

You can write that in C++17 with only slightly different syntax (and it is actually really nice for being C++):

#include <stdio.h>
#include <tuple>

std::tuple<int, char> myfunc() {
return { 0, 'a' };
}

int main(int argc, const char *argv[]) {
auto [ err, c ] = myfunc();
if (err) {
// handle
return err;
}
printf("Hello %c\n", c);

return 0;
}

In Polish language we use herbata word. It is a herb tea. Its unique for whole Europe. I think mostly because it was not popular in Poland for ages. People drinked here honey, milk, mead, beer. Compared to it tea was lame. People added wine, ice cream and other stuff to make it taste better.

Also, there were other brews, for example from mint before here. So herbata was not exciting in any way. But eventually it made it through and is now main beverage here with a distinct name across whole Europe.
If you are not using something to aggregate statistics using something like prometheus or graphite then logging good events can be really useful in order to produce statistics by doing text processing on the logs. It can also be a good first step towards introducing something like prometheus or graphite. Once people can see the kind of insights into an app you can get from dumb logging and manual text processing it becomes easy to sell some kind of metrics recorder to the team.
Hospital support staff, like cooks and janitors.

I'm not knowledgeable enough to properly recommend a book on the subject so take this with a grain of salt, but I thought the historical (and opinionated) overview of the evolution of English money in Christine Desan's "Making Money: Coin, Currency, and the Coming of Capitalism" was interesting https://www.goodreads.com/book/show/21492062-making-money

I like this quote about how financial institutions evolved:

"It happened improvisationally, indeed probably unintentionally. Participants solved one problem and created others; they reacted as often as they acted affirmatively; they moved by experience and intuition, without an overarching theory; and the whole affair took decades, involved many different actors, and coheres largely in retrospect."
Crisis Leadership
Speaking from experience, large US defense contractors are incapable of producing a single sheet of paper with the proper signoffs to make a plan to schedule a meeting about the need for ventilators in under two weeks.
Ask HN: Can we hack together a ventilator?
There are already some good open source projects hacking together ventilators. It occurred to me that we might be able to combine a computer fan (or two) together with a fan controller chip and an arduino to make a ventilator.

I don't know enough about the fan controller chips, though, to do this. Does anyone have an opinion?

Finally here's the best open source project I've seen as a starting point:

Sir Patrick Vallance: 60% corona infaction rate necessary for “herd immunity”

Don't assume. You can calculate it in spreadsheet.

In the long run we are all dead. We don't need to believe they hold true. Certainty is not part of this world. Because you never know is just rhetorical argument. Quantifying risk and going on that is good enough.

Move 97 of game 4 didn't seem to help AlphaGo and a human certainly would have vetoed it.
Do flocks of birds or schools of fish fly or swim in random directions? Or do they swarm together in discernible patterns? At core we share similar brain structures with them.
It's essentially a somewhat more intense flu with no herd immunity, which means instead of spreading itself nicely throughout the year it comes in at once in a massive exponential spike that blows out the medical system

I'm kinda curious though if this quarantining is also gonna significantly help with any other diseases already out in the wild. Would be nice if we ended up also clearing out some of the regular flu stains too

Small correction: I forgot to sort the indicies by first appearance to guarantee by-order-of-appearance, so this should be {x@{x@<x}*:'.=x} where I've added "{x@<x}" - sort ("x at grade x"). Inner x and outer x are not the same one, this is an implicit argument; you can extract it out to a named function or name the argument e.g. {[v]v@<v} -- and I encourage you to do both when you start. But over time, "{x@<x}" becomes its own object, in the way that the word "while" is its own word and not the 5 letters that make it.
This is the last thing humankind needs: nuclear powered battlefields.
Maybe not for DOS, but for CP/M it most certainly is true, since the length of a file in bytes is not stored anywhere. Only the number of (typically 128 byte) sectors.

For binary files, you just assume there is padding at the end of the file to the end of the sector. For text files, the SUB code was used to indicate where the file ended.

That definitely shouldn't be the case. Epidemics/pandemics are a situation of "we either make it together or we don't make it at all".

Since you are a professional in the field, I am asking your help for brainstorming useful, contributory things for people like me (and others) who are feeling the need to DO something.

If hacking up ventilators (like in the OP) is not a great idea from your perspective, can you suggest anything else?

And, THANK YOU for doing the job you do, from someone whose life was affected by people like you!
This is encouraging, but the key would be pushing this to clinical trials ASAP.

Efforts need to be made to drastically trim the time-span it takes for a successfully trialed COVID-19 vaccine to get from laboratories to hospitals and into patient's veins.

I'm sure many countries and billion-dollar companies are at it, but making it affordable to people who need it the most is a challenge in itself.

>This article is pretty confused.

Articles like this are often written by someone that manages a trivial or non-critical path system. They have strong feelings about logging because they lack other things to have strong feelings about.

This person seems confused in general. They say "don't log, send it to sentry". Sentry is logging. Sentry is usually configured as a logging destination. It just does some preprocessing on those logs to aggregate and enrich them.

I don't know anyone that fishes through text logs over ssh anymore. We use simple automations to roll everything up for convenient access.

Furthermore he overlooks other use cases for logging. Including analytics, fixing concurrency/heisenbugs, and a myriad of other problems that logging addresses.
>Quantifying risk and going on that is good enough.

Because most people who are blindly buying indexes around the world thinking they are diversified and DCA are certainly doing that…
Of course it isn't, you couldn't have arbitrary binary files if one of the 256 possible bytes was reserved.
That's why getchar returns int and not char; one char wouldn't be enough for 257 possible values (256 possible char values + eof).
The title is silly.

Of course antibodies exist against the virus - otherwise the fatality rate would be 100%. You don't just survive an infection, your body creates antibodies, and they stay in your body for a very very long time. That's the whole point of vaccination.

Once this blows over I'll go get my blood tested for antibodies for the virus - will be interesting to know if I had it.
The Snopes article is perfectly clear; the answer to the question "Did Trump call the coronavirus a hoax?" is no and atoav was precisely wrong on that point. There is a Hoax hoax afoot here.

Trump banned travel from China in early February, and the hoax comment is late February. It is pretty obvious from his actions that he takes Coronavirus much more seriously than the flu whatever his public message.

> He's made a mess of this primarily. The buck stops with him.

Yeah, but we don't know how this plays out. There are a bunch of drugs against Coronavirus starting to complete clinical trials, so this may actually get nipped in the bud as far as the US is concerned. It is a real test of the Trump administration though, no argument there.
Well, they faced something comparable 102 years ago ... The world didn't end, though it did suffer greatly.

Seconding this. It's a fantastic book, a little outdated but easy to fill in the gaps.

I think the best route is to read this, skip all of the books marketed to retail traders. Read the things the professionals read like the CFA study materials.

I have almost 10 years in the finance industry, both buyside and sellside and my take is that, while there are some fundamental principles at play, the world of finance is too messy and complicated for any one book to describe it. An even stronger statement I am willing to make is that no one person correctly and fully understands the financial system.

So, once you accept that there is no "correct" answer to how the financial system and how markets work, what's left to do is to follow what's happening in the world and try to build your own mental model.

One source I'm a big fan of (and has a bit of a cult following in the financial world) is Matt Levine's "Money Stuff" blog:
https://www.bloomberg.com/opinion/authors/ARbTQlRLRjE/matthe...

He's engaging, funny, talks about interesting topics and, most importantly, he's _rarely_ wrong. It's a rare thing seeing a journalist talk about your specialty subject and actually being correct.

Similar source is Felix Salmon: https://www.felixsalmon.com/

Similar league as Levine, but I find him slightly less engaging, for whatever reason.
Some updates on Computer/Human interaction from a Go AI author. Opinions are my own.

In the Go world, the relationship between computer and human has turned into one of analysis. Every pro in Asia has a powerful GPU-equipped system with LeelaZero or KataGo or Minigo installed, and they use it to study openings and analyze their matches. LZ/MG are similar in that they're from the AlphaGoZero generation of bots, and thus are hardcoded to 7.5 komi and don't play well with handicap stones. KataGo is the open-source project with the newest ideas, using (among other things) territory ownership prediction, allowing it to handle arbitrary komi and handicap. Many pros are switching to it for this reason. All TV broadcast channels use AI for both winrate prediction and variation analysis. They'll report the predicted winrates by all major bots.

There are definitely AI-inspired opening sequences, but I would say that by and large, pro play has stabilized to just be better. A few years ago, pros would just mimic AlphaGo just to see what would happen, but there's becoming a better appreciation for the many different opening styles that are becoming possible, now that we have AI to analyze them. The strongest pros are the ones who spend the most time on their computers.

Despite a few extra years of research, all available AI systems still fail at ladders regularly. Some may have had ladder routines hardcoded in, but these routines still fail at loose ladders and the many wonderful ladder variants out there.

In the online Go world, cheating has become rampant. Top echelon of games/accounts are essentially just people competing on how beefy their GPUs are, and human professionals complain that they can't actually get a game against another person nowadays.

Professional tournaments / pro qualifying exams have had isolated incidents of cheating which are usually fairly obvious, as human playstyle is still recognizably different from computer playstyle.
Note that this is a Dutch news channel, and the article is in Dutch.

Usually, when they report on a discovery done by Dutch researchers, it is considered newsworthy because the researchers are Dutch, not because the research itself is particularly noteworthy. So in addition to the usual reservations that one should have when noteworthy discoveries make the news, there's an extra reason not to hold your breath until you see this appear in international publications as well.

Company wide meetings are a great way to keep everyone on the same page and aligned to the same goals - but they start losing effectiveness as your company does more stuff. I think trying to keep things two-way is incredibly challenging as your company scales, if you don't do that, then it's just a presentation and not worth attending.
