Is it really necessary to use a sterile valve for a new patient affected by the same strain of virus. I would expect the hospital to reuse a valve, instead of letting a patient die without the ventilator.
They say “his address was posted online” like it wasn’t displayed on his own website. Pointing that out hardly counts as doxxing.

I don't understand the emphasis on homebrew ventilators. Why start at the drawing board, when existing manufacturers have the designs, manufacturing equipment, usage, testing procedures, etc. figured out?

The engineering effort that would go in to a successful maker-ish ventilator would surely be better utilized in other areas.
Given the choice between contracting the disease or taking the vaccine you would take the vaccine. But, as the spread had stopped, it was a choice between taking the vaccine or having a 0% chance of catching the disease which had already died out.

It's comforting in a way, to see that Italy even now isn't so overburdened by the pandemic that it can't engage in its time-honored habit of striking at the drop of a hat.
I’ve referenced Geerling’s ansible code on GitHub dozens of times over the years, it’s been an invaluable learning resource.

Curious about his take on ansible+k8s, my impression was largely that k8s+dockerfiles have taken over most of the corners where I would have previously used ansible
Note that in both cases there is a selection bias, due poor testing, and having the majority of initial reported cases being severe enough to reach hospitals. In my opinion, South Korea has better data, due to massive testing, and not having a completely overwhelmed health system. The rate there is 0.6%, which is still significant.
Really bad example... Memset to zero members of a structure this way is actually something that should trigger a compiler error, because it makes no sense. I have limited understanding of C these days, but I consider that a good thing, because it allows me to look with fresh eyes on the crap I wrote back in the days. And this is one of them. It's nonsensical and similar to the general linux sentiment of naming your variable like random garbage. It's brainfuck. The only thing I can say with some distance is that exploiting undefined behavior in pretty much all cases should yield a compiler error.
There's a bunch of different studies, mostly focused on the results from China, but there's also a few things trickling out from other seriously affected areas.

Basically 15% of people (of ANY age) who present symptoms get so sick as to require hospitalization. Younger people have strong bodies and with an ICU bed, drugs, and proper medical care they are able to recover over the course of a few weeks. But without that intervention, they have a good chance of dying.

That is what happened in the last days of the Wuhan crisis (peak fatality rate: 5%). It is what is happening now in Italy (fatality rate: 8% and climbing) and Iran. That could be the rest of the EU in a week, and the USA a week after.

When the healthcare system is over capacity, the "needs hospitalization" number becomes the fatality rate.
Hopefully they won't get sued for using uncertified parts. Especially if somebody dies.
I'm not saying that people don't need material wealth to survive in our society. I think that wealth can come from somewhere other than packing a petri dish bar with patrons who want to drink. For example, we're realistically looking at govt intervention at some point.

It starts with a concerted decision that lives are more important than money. If we can't get onboard with that, then there will always be people that put their well-being over others.
The worst is behind China because they've instituted heavy lockdown measures beyond what would be acceptable in the US, and enacted emergency measures like constructing temporary hospitals and isolation centres. They're still under lockdown - Beijing for instance is mulling a mandatory 14-day quarantine for anyone entering the city. So far, only a handful of other countries, mostly Asian ones, have had success slowing down this virus.

Most of Europe and North America is on a steady exponential curve upwards with no sign of slowing down yet. Germany has already clearly said that they expect 70-80% of the population to be infected eventually - 60M people, of whom ~2% or 1.2M will likely die. Scale that up to the USA.

Without a vaccine, the only way this virus peters out is through eventual herd immunity, which will require a sizeable fraction of the population to catch it.

Yes, it’s an emergency, but many parts of the process just take as long as they take. Throwing more people and money at the problem can ensure that we have many parallel solutions in the pipeline, but won’t get us there faster.

How would you implement this? For example, use-after-free is undefined, and difficult to detect.
If tens or hundreds of thousands of people were dying every day from the virus, might we find many volunteers willing to be intentionally exposed to the virus in order to rapidly test the efficacy of a vaccine? I imagine so.

I believe the magnitude of this pandemic will in time push us (rather violently) to think outside the box.

Most relevant to the thread, if someone wants to do easy analytics on pcap, enabling regular dataframe / sql / dashboarding code to work on that. Not interesting to traders, but of it/sec/ops, seems so! Both for forensic, monitoring, & controls.

For financial use cases, the most sensitive autotrading, yeah, I'd expect ASICS for serving simple models to win for stable algs, and I'm sure all sorts of other interesting things. At the same time, I'd expect others would enjoy something more manageable when less sensitive. Improving the whole Excel / Bloomberg / Factset etc. experience is probably a saner starting point though. I'd turn it around - where would you expect the most useful starting points to be?

This is either a straw man argument, or I disagree that there should be long term unemployment here. Govt programs and laws will probably be needed to provide that safety net.

I'm not saying that death rate and unemployment are unrelated (equating lives and money together). I am saying that we should prioritize lives first, and figure out the money once we stop the damage.
Your comment is ironic on so many levels. Cheers to the OP. I think everyone needs a positive message right now. Thanks for delivering one.
The number coming out of China do not seem... completely above board and have been questioned by many people. Also as other have said, China, being an authoritarian country, had the power to lock down in ways that the US simply is not ready for or willing to put up with. Already in KY we've had a man who refused to self isolate after testing positive so now we have to station someone outside his house. We have 21 cases total.
You just started your comment by listing details of your living situation, however.

This is false. The peak of the Spanish Flu was during the fall of 1918. The midterms that year went forward as scheduled.
The actuarial value of a human life is difficult to calculate, but it is definitely above the economic output. There are large 2nd order effects- the pain of those left behind. I picked $100k because it made the math easy, but it's also between the $50k and $129k numbers i grabbed off Wikipedia.

Also, this is one of the rare times it does makes sense to go with mean as the measure of center.
The neuroinvasive potential of SARS‐CoV2 and Covid-19 symptoms
I wish I could remember the source, but degree of exposure matters. I suppose you could explain this as "flattening the curve" writ small, as the bodies defenses don't have time to build up. This is why healthcare workers can get sicker than ordinary folks, because they are swimming in virus.
Apparently Austria just banned any gatherings of 5+ people. Are we in the US behind?
For places that don't want to close restaurants. Would it be legal in America for the restaurants to check everyone's temperature before they enter the premise (guests+ cooks+ waiters).

Wouldn't be perfect but could slow transmission down while giving them a way to earn money.
That's no what my comment said. The people who will be hit the hardest are those with little money and little employment protections. People working casual in these restaurants will be left with no job and no support.
Lawyers like the second scenario because then the doctor isn't liable in the 2% case. Most people, especially in emergency situations prefer it when their doctor does what they think is best, I believe.
It has always been the case that 1% of humanity pulls the other 99% forward. We do not need everyone to be a genius. We just need one.

We do not need everyone to be Martin Luther King Jr. or Gandhi, or Michelangelo, or Bach or Einstein, or Shakespeare, or Newton or Galileo we just need to be smart enough to recognize when one of them is born amongst us. We've not always been good at that.. but we've been getting better at it.
>> I am saying that we should prioritize lives first, and figure out the money once we stop the damage.

False dichotomy. There are plenty of economists and accountants and others who can work on the economic relief package and do so in a meaningful way while scientists and medical teams (plus politicians) handle the lifesaving operations. There is no reason they cannot run in parallel.
I don't have any objection to developing and distributing a vaccine, but it's deployment without sufficient testing. Had the disease become widespread, as you note it would have been worth the additional risk, but in the event, it made the occurrence of any serious side effects seem more egregious. These kinds of things just feed into the anti-vaccination movement and if that overall hurts vaccination rates long term, rushing a vaccine that ends up having side effects could negatively affect public health.

Well, the announcement hasn't been as clear as "By definition." They only said that "some or all of the batch may take place remotely over video."

If the coronavirus pandemic is under control in the U.S. by June, and YC decides to run some of the later parts of the batch (such as Demo Day) offline in SF, that could be a problem for foreign founders who might still be stuck in their own countries or can't get a visa on time. The deadline is drawing near. Without a firm assurance that there will be no location requirement whatsoever at any time, a lot of foreign founders might decide not to take the risk. But YC is not making themselves clear. As I said, there's a huge difference between 99.9% remote and 100% remote.

Anyway, I just saw your more recent comment about over-interpreting the word "may" and I fully agree with what you said there.
And they have roughly 5 times the beds per 1000 people too.

I won't be touching delivery food or fast food (or going to any restaurants) until this is over. I feel terrible for the workers in these industries and I hope we pass some kind of mortgage/rent pause and relief to people laid off or not scheduled but stopping the spread of the virus has to be our number one priority.

Conspiracy theory : maybe the government wants to have nhs to collapse as a way to turn the public against it, then when the crisis is over nobody will object to its privatization?

You should note that:

* quarantine laws and powers have existed for thousands of years in all forms of governments, and much more draconian steps have been taken in this country in the past -- which were obviously reversed after the crisis.

* speaking of, these laws & powers have been on the books for quite some time -- not exactly in a sub-basement with a burnt-out lightbulb and a sign reading "Beware the Leopard" :-)

* the majority of people are OK with lawful extreme public health measures in the face of an extreme pandemic; that number increases as more people get sick and die from the disease.

* most people also uniformly agree that we don't have time right now to re-litigate the hundred years of legal analysis, court decisions, and public health science that led to modern public health law just for the benefit of the latest generation of libertarians.

* most importantly -- flippantly shrugging off the death of a million (or THREE million) of your countrymen as an argument against closing restaurants is going to make most people think you're a sociopath. Unless you're in an impermeable bunker with a literal lifetime supply of every need and no human relationships, the rapid death of millions of Americans and the attendant culture and economic shocks should upset you, or at least make you anxious about the future.

Stay healthy, and good luck with those back-of-the-napkin epidemiology and civil rights analyses!
Some activities lend themselves well to amateurization. It's hard to imagine a world where people need a professional license to write computer programs or publish articles. Not all professions are this accessible though. Perhaps amateurization is correlated with benign consequences for being wrong. We don't see amateur engineers, doctors, lawyers...

WalkMe Uses Druid and Imply Cloud to Analyze Clickstreams and User Behavior
Cultishness is a spectrum, not a binary. C has always had a certain proportion of adherents who believed that "performance" (of code that implements microbenchmarks with unlimited hours of manual tuning) is the most important aspect of a general-purpose programming language, and that the problems of undefined behaviour are insignificant. I would say that both those viewpoints are crazy, but they are increasingly becoming the mainstream in the C community, via the mechanism described in the link: more moderate people are driven out, rendering the community more extreme, which then drives more of the moderate folk out, and so on.
> During software updates, we enable the new version for a subset of users and ... compare how the new version is performing vs the previous version. Any regression in the metrics gives us a signal to abort the update and revert

How do you account for the possibility that the update only performs badly because it’s different than what users are used to, but would actually be an improvement in the long run?

I wrote about that particular topic a couple months ago: https://www.ansible.com/blog/how-useful-is-ansible-in-a-clou...

The answer is: "it's complicated" — there are still many scenarios (even in a more 'cloud-native-oriented' shop) where you need automation to fill the gaps between more provisioning-focused tools (like Terraform) and more scheduling-focused tools (like Kubernetes).

Sometimes it's in application build or deployment scenarios, sometimes it's in stringing together different platforms, and in some cases you could even argue for skipping Dockerfiles entirely and using a tool like Ansible to build containers.

A lot of it is highly dependent on your team, your resources, and the amount of application tooling you have that's not 100% cloud-native, serverless, [insert other buzzword-worthy tech here].
No one is using the Lua reference implementation when performance is required. I haven't used Lua(JIT) for years, but when I did, its performance was approaching C-compiler in some cases. Although a tracing JIT does have its weaknesses as well.
Uhhhhh ok. I'm not really sure why you think I said they can't run in parallel? What I am saying is that you can't prioritize money over lives and actively do things to harm the life of others.

This whole comment is about the approach to covid-19 where life goes on as normal and you don't practice social distancing at all. One argument for people that do that is that they can't take off work because their businesses are open and will fire them. I believe the businesses should be forced into social distancing and provided financial help if unable to do that. We're actively going to see this happen in the next week—it started tonight—will it be late?
Most companies are not Netflix but all cloud customers can learn from their public design discussions. The only reason I mentioned AWS is that they are Netflix a high profile AWS customer, and their lessons in cloud architecture apply pretty cleanly to GCP. You cannot assume an SLA of 100 percent, even if it works out that way on shorter time scales. It's really no different than running your own datacenter, so I don't know where this 'monitoring will prevent catastrophy' fight is coming from.

> You cannot assume end customers are running thing at the scale or with the fault tolerance of google, or Netflix.

Correct, but there's a gradient between 'we have 10 copies of the service in 10 different countries and use Akamai GTM in case of outage' and Dave's one-off-VM. One-off VMs are fine if you know what you're getting into, and I use that setup for my personal, lowstakes & zero revenue website. But if you are a paying cloud customer, it makes sense to pay attention to availability zones regardless of scale.

And sure, there might be a market somewhere for a more durable VM setup. At a past non-profit job we provided customers the illusion of a single HA VM using Ganeti (http://www.ganeti.org/). But it's not clear to me that the segment is viable -- customers at the low and top end don't need the HA.

Warning when optimization passes take advantage of UB is a reasonable desire. The compilers are getting increasingly good at this, but I believe it would be far too noisy to blanket enable all of that.

Yep. The author's mis-statement:

> In C89, undefined behavior is interpreted as, “The C standard doesn’t have requirements for the behavior, so you must define what the behavior is in your implementation, and there are a few permissible options”.

Wrong. The entire point of "undefined" was to mean "the standard imposes literally no requirement."

"Implementation-defined" and "unspecified" are essentially what the author is thinking "undefined" means. To quote the standard:

> 3.4.1 implementation-defined behavior unspecified behavior where each implementation documents how the choice is made

> EXAMPLE: propagation of the high-order bit when a signed integer is shifted right.

> 3.4.3 undefined behavior behavior, upon use of a nonportable or erroneous program construct or of erroneous data, for which this International Standard imposes no requirements

> EXAMPLE: the behavior on integer overflow.

> 3.4.4 unspecified behavior use of an unspecified value, or other behavior where this International Standard provides two or more possibilities and imposes no further requirements on which is chosen in any instance

> EXAMPLE: the order in which the arguments to a function are evaluated.
