It still works for killing E Coli (and viruses based on using it on hands).

And you still have at least half of the filtration efficiency. Unsure if that means 90% instead of 95%, or 47.5% instead of 95%, but that's still a gain.

The pressure drop was comparable to the other methods, so you're not going to asphyxiate yourself according to the publication.

Bill gates benefits more from the economy starting that not. As you say he is not poor and hence he doesn’t need to take any stance. He can be quiet and feed his kids. He is saying what he is saying to bring some sense to this society as a person who has seen the devastating effects of not taking measures to containing an epidemic. We have leaders that absolutely should be removed from office as if we don’t do that This can disintegrate into anarchy.

Also, What’s your plan ? open the economy, earn money to feed your child who might get sick or worse you may get sick and die and then they are whose responsibility? And as for the old people let them die? Who needs them?? I would suggest you Channel your frustration to making your govt act on helping the poor people and stop worrying about the incumbents relection.
A busybox-like set of tools would not be very useful without a package manager and the ability to install arbitrary software like compilers, editors, and the like. Just out of curiosity, I counted how many formulae I have installed with homebrew on my Mac:

$ brew list | wc -w
244

That's probably not that many compared to some people out there.
What's confusing about this to you? Would you prefer OP to default on their mortgage, in which case the tenants would likely get tossed out anyway?

Most of that is good. One factor is if you are writing code for yourself to maintain or a team.

If it is for a team, you need to take into account if other people can understand your code. Practices like SOLID and just using the type system well don't make it slower to write code but will help maintenance down the road.
Thanks, was having a very hard time reading it with all the broken images.

I have the entire Asterix collection in Spanish (perhaps the most prized inheritance my mother left me), and I don't think the translations are as bad as you say they are.

If you don't derive satisfaction from your productivity and instead are optimizing you're output:effort ratio, remote really pays off. On-site only is skewed towards increasing output since effort is largely fixed, but remote allows you to begin trimming effort quite a bit.

But a lot of people treat work as more than a transaction. That's fair but not for everyone.

I think we already have tons of brilliant people developing video codec. I'm sure they are all well aware there isn't a way to define part(s) of a video a slide show. What is missing is people pointing out how silly this is. The keyframes also define the seek points. Its a mess.
Yup, it's continuous, not discrete.

My running joke with the "up to 3 days" figures people keep sharing is that you could get infected "up to 3 miles away" by someone sneezing if the winds/temperatures are just right and you're EXTREMELY unlucky.
So we're accepting E.coli as a benchmark here, because we're pretty sure it destroys the viral envelope?

I'm curious why UV light couldn't be used, or even X-ray machines, or one of those "gamma knife" machines.
There was another study from 2011 showing the use of steam bags in microwaves, but localized extreme temperatures might destroy microfiber structures like putting microfiber cloths in a clothes dryer.

In a conventional oven, 75 ℃ / 167 ℉ for 30 minutes is sufficient to inactivate SARS-CoV-2. If someone were worried about packages, mail or objects being contaminated, placing them into the oven like this would probably work if allowed to reach that temp internally for that time.

Why would it be easier/faster for a company to make their own design than for existing manufacturers to scale up production? Wouldn't it make more sense to throw resources at scaling existing production than new designs which would, themselves, then need to have production scaled up anyway?
Says 56.33% efficiency after OH bath...too much for me. I too have a Breville Air Oven, and will simply collect a few masks and bake. A few percent efficiency drop is more palatable.
Food dehydrators may also work well for this. They usually range around 90-140f.

Many of them have stackable horizontal racks which may make it possible to 6-12 at a time.

Microwaves work by heating the water in food. They don't work properly on paper.

The dryer is a much better alternative.
It's interesting that they tried UV light and as far as they know it works for sterilization but they're not sure if it would cause the mask to fall apart eventually. Maybe there's an optimal UV frequency/intensity that kills the virus but doesn't hurt the mask.

> In summary bleach and microwaves were failures at point of care because the bleach
gases (skin and respiratory irritants) remained after multiple strategies were used to remove them, the microwave melted the masks and soaking them first led to reduced filtration. EtO, UVGI, and hydrogen peroxide decontamination were safe and effective in the models tested but it is not known if they would retain filtration, material strength,and airflow integrity with repeated use. EtO, UVGI, and hydrogen peroxide limitations include time from decontamination to reuse and available space and materials to decontaminate in an OR setting. 70C /158F heating in a kitchen-type of oven for 30 min,or hot water vapor from boiling water for 10 min, are additional effective

This coronavirus event will certainly inspire evil middle-eastern terrorist groups to begin researching on bio-weapons. When they discover how easy it is to synthesize base pairs, we are utterly fucked.

I feel the same way about debt. Financial advisers, business and personal, often push you to take on higher levels of debt. It looks great on a spreadsheet, showing how you can make free money with clever financial instruments, but it washes the risk under the carpet.

I've been under pressure at various times in the past year or two to take on debt and increase burn rate in order to 'grow the company', and I'm overwhelmingly glad now that I did not. My empire is tiny but it's solvent and can stay so.
Why would you ever bail out an industry that is not essential to society?

I've mentioned it before, but there is already an American company that makes a simplified and hardened version of a ventilator that is aimed at meeting surge demand during a pandemic.

They have already gone through the regulatory approval process and the cheapest model was retailing at about $3,000 and not the $50,000 number Ive seen tossed about for models with all the modern bells and whistles.

When you need to ramp up production quickly, simpler is better.
I wonder if there was a lie of omission by the health professionals: "N95 Masks won't help the spread [because the general public will touch their face without washing their hands after removing the mask, thus masking the mask a moot point]" ~ the brackets representing the "lie of omission" part. I honestly don't know, just wondering out loud...
Are they ever activated at times you aren’t expecting them to be? I assume I would have a noticed the little green light on my mbp if the camera was being activated against my wishes.
It's not censorship we should be worried about. It is the misinformation campaign that left-wing liberals are are pushing to destroy the economy.

Media and the politicians exploiting it are way more dangerous than whatever this stupid virus can do.
I'm right there with you, probably has to do with many of them having never seen a manufacturing facility. But they do know how to write "Those jobs are never coming back!"
There's also a distinct probability that your pencil will suddenly levitate an inch then drop back. I'm not kidding.

Simply put first comes health then comes wealth. The other way around dosnt work. The problem is your leaders are putting wealth first and health may be second at best. At worse it’s wealth first , re-election second everything else will take care of itself -with “love and protection”. If you don’t want to be the lost generation change your leaders before its to late.
Make sure you are using a medical grade (oil and particulate free) compressor, because aerosolized machine oil and micro metals are super bad for people to breathe in.
They included UV Light in the study. It is comparable to the hot oven.
Could put a filter on the exhalation port, I believe some of them have one.
Although buying existing ones is zero-sum: assuming the worldwide demand exceeds supply and, as such, those ventilators would have been sold anyway, his buying of those ventilators just swapped the shortage problem to a different group of patients.
And shockingly, only one comment on HN, plus this one.

It is a call to action. Will we act?
How can you prove you personally didnt benefit from the situation due to suppression of African Americans and Indians in this country? May be they could have gotten your job or your seat in an ivy league school.

At least no libertarian that I know support reparations. They believe their position of weakness led them to be taken advantage of so they kind of "deserved" it. Or their labor were put to better use.
> Note that when using static linking, you don't get a copy of everything, just everything you actually use.

Which is a significant fraction of everything even if you call simple like printf.

> It doesn't alter the fundamental point: shared libraries save both persistent storage and runtime memory.

I fail to see the argument for this. Dynamic linking deduplicates dependencies and allows code to be mapped into multiple processes "for free".
That video gives half lives of 5.6 hours for stainless steel and 6.8 hours for plastic, not 72 hours.

72 hours is the time it gives for the virus still being detectable/viable on those surfaces, which is different than the half life.
However any cookies set via HTTP, like http secureonly cookies that tend to be used for logging in, are exempt from that seven day limit.
I think some saunas can get to that temperature.
Glibc does not really support static linking.
Are you sure? I've been running Linux for a long time with no page file. From 4gb to 32gb (The amount of RAM I have now) and have literally only ran out of RAM once (and that was because of a bug in a ML program I was developing). I find it very hard to believe that you experience any swapping at all with 32gb, much less "lots".
Suspend those too.

It's turtles all the way down.
The free piston compressors don't use oil as far as I have been able to tell. I believe they are diaphragm pumps.
It was probably a little more involved than that, but not by much. The real story is that asinine regulations and bureaucracy aren't letting hospital administrators do the same!
The problem isn't that there is a lack of ventilator designs it's that there's a lack of physical ventilators which means it's a manufacturing/supply chain/logistics problem not an R&D problem. That won't be solved with yet another design.
Yeah I'm willing to accept they improved over the years, I'm just reticent on getting another based on experience.

We use our Miele cat&dog model less than we should, but when we do it's noticeably stronger. Cord & bag is just inconvenient after you get used to the Dyson for daily touch ups (I swear my dog puts 90% of his calories into hair production).

Not to be rude or anything but if you continue down this road productivity might be the only thing going for you and you'll soon realise you are the only one who can work with your code.

Substitute software engineering with any other engineering descipline with "I stopped worrying about best practices" and you will be able to see what's wrong with your approach. But then again, if it's php, your domain doesn't require too much care.
There is still taxes, mortgage, upkeep, and many other daily expenditures of life to pay.
So does a sick person not on a ventilator though, and there are many more of them.
> 1st party httponly secure cookies will be erased in seven days.

httponly cookies can't be set from JS, and the seven day erasure only applies to cookies set from JS. That's why they're the recommended method for keeping a user logged in.
I wonder if we could vacuum pack the masks and put them in a sous vide, it would be a lot easier to implement than finding enough ovens for all of the masks.

As for the bleach leaving skin and respiratory irritants, maybe hypochlorous acid (HOCl) might be a good alternative?
Clojure doesn't have much over JS except for macros, but today you can achieve the same with Babel. If you stick to writing JS in a functional programming way like Clojure encourages to do so, you are pretty much just writing Clojure but with a little bit more verbosity for keeping things immutable and to compensate for JS's lack of standard library (fixable with libs like lodash and immerjs).

When devs talk about data in Python their are referring to data science, it has a big ecosystem to support that, Clojure doesn't. Data-oriented in Clojure means using generic data structures like maps/vectors/sets to represent information, instead of creating classes for everything.
Finite descriptions are countable. Axiom of Countable Choice is not counterintuitive like Axiom of (Uncountable) Choice.

You can order the set of all definitions, by prepending each definition with its length and then using the ordering (numerical order, alphabetical order).

How is using E. Coli for testing sterilization an accepted protocol? Viruses, even big ones like corona viruses, are much smaller than bacteria. Viruses are very very different than bacteria.They should have tested the sterilization procedure on a virus. Yes, it is harder but lives are at stake.

Escherichia coli is a rod-shaped bacterium. Each bacterium measures approximately 0.5 μm in width by 2 μm in length.

Everything your doing is perfectly ok as long as the productivity gains are there.
The lack of a generic function where something occurs 5 times has potential future risk only because it makes refactoring harder. But if you don't deliver a product because your lost building generic things then you don't get to have legacy and support problems.

In fact I'd say that until someone is able to quantify the revenue lost and be able to directly tie it against the choices you are making then stay the course.

You're right, I misremembered the video. Still, 72 hours as the time when the last virus particle probably dies still seems a bit risky.

You’re presenting it as if it’s a binary choice. It’s not strictly binary, and creating a “one or the other“ straw man to pretend it is binary so that you can grandstand is counterproductive.
