Ask HN: Recommendations for free, easy in browser video meeting rooms?
I'm in France in quarantine, as are a lot of friends. I'd love to have a space where we can pop in and out of a video meeting – ideally a URL that's always available, where we can drop in and see who's online. It'd have to be free and ideally in browser so it's easy for everyone to use.

Does anyone know if this exists?

I'm sure I've seen a bunch but can't remember any names.

Thanks!

This isn't very weird, is it? Most people didn't start to hear about COVID-19 until January this year and many others didn't start hearing about it until people got infected in their countries.

As with everything with clinical trials, even if it seems to be helping, it'll take many months before it'll be prescribed to people for treating COVID-19
If the SAT were a joke, you wouldn't expect scores to follow a bell curve with only ~0.3% of people getting a perfect score, but they do.
Not a false dichotomy at all.

People have about 18 hours in a day to do stuff. Basically all of it has a carbon footprint.

Which do you think is higher: commuting to and from school/work and using electricity for eight hours, or just the using electricity part? Flying to a business meeting, or conducting it with videoconferencing?

The answer is obvious. Also, this is exactly what responsible climate activists advocate for: shift activity to lower total emissions, and electrify everything which can be, while titrating off fossil fuels and ramping up renewable electricity.

I’m an economist, I get your Cost Benefit Analysis. But I think you’re missing two factors: firstly the psychological cost a community where senicide occurs (https://en.m.wikipedia.org/wiki/Senicide).

Secondly, the fact that governments are not rational. This UK government is beginning to wake up to the fact that it will lose all public support in coming months and is making belated attempts to shore up some public support.
The recovering youth are getting breathing problems that aren't going away as well. It would be in their interest not to get it.

Humans are irrational creatures. They're not robots. This is a feature not a bug.
IMO it's a security problem in practice - it means that you have a lot of organizational resistance to doing things like regular software updates, because you end up with this one server that's been hand-crafted that people are too scared to touch. Or, analogously, if you want to introduce some new sort of authentication/auditing/etc. protocol to the system, people will worry that they won't be able to find every use of the old thing and won't make the new thing mandatory. It also means that it's a lot harder to test changes, because you don't know what you need to set up to get a full test/QA environment going.

It's not a vulnerability in itself, but the fear/stop energy created by artisanal small-batch infrastructure is a good way to set yourself up for vulnerabilities being exploitable. (See, for instance, Equifax being hacked by a two-month-old Struts vulnerability - you can theoretically argue that Equifax is a big company and should carefully audit their dependencies, but a much more practical argument is that Equifax should have been ready to patch within days, at most, of the vulnerability being announced.)

The actual ToB report identifies another reason which I didn't think of:

> Ensure that all backend infrastructure is re-provisioned between elections and not shared between elections/clients. Each server should also receive its own unique SSL certificate and credentials. Use infrastructure-as-code tools like Ansible and Terraform to automate and manage provisioning.

Apparently there are two concrete problems:

1. All Voatz backend servers share a single wildcard certificate, and they think that automated provisioning would reduce the incentive to do things like this.

2. Every Voatz election uses a custom iOS/Android app delivered via TestFlight / Google Play Beta, because of some design choices in the protocol related to having a single shared backend (S3, MongoDB, etc.). They think that if there were infrastructure-as-code for the shared backends, it'd be easier to provision one instance per election and easier to make the client change to use a single client for each election, blocking potential attacks on the page that links you to the sideloaded app.

Youth also doesn't want to deal with this disease. I'm 23 y.o., healthy as far as I know, but I still don't want to catch this disease. Why spend 2 weeks on the bed dealing with the worst flu, risk getting hospitalized? After all, even young patients can be hospitalized, even though fatality rate is lower. I vote everyone stay home for the time being.
Indeed -- as far as I can tell the changes are not behavioral, only aesthetic.

That said, they do look really nice, and are (IMO) some of the best-looking hover effects I've seen in years, so kudos to Apple on that! Microsoft can't even seem to get its hover-effect strategy aligned within built-in Windows 10 apps...
GP comment seems completely relevant to SAT subject tests to me. The point is that removing a test from consideration, even if it's not the only test considered, makes it easier for rich people to game the application process.
The page isn’t loading so I’m not sure what they’ve got, but I’m still trying to get answers to a question I have. I did research Tuesday and it seems like ventilators are positive pressure only, and they cycle between a low pressure and a high pressure. If this is the case, could an air compressor with a regulator be used as the pressure source? If so, a small device with just two pressure regulators and an electronic valve could be used to cycle between high and low pressures for each patient. I keep seeing open source ventilators that use a fan and a motor, but those seem likely to fail. Air compressors are abundant and could literally be taken from construction sites to be used. You put a pressure regulator to go down to the (very low) pressures one might want as a maximum for any patient, then you can gang that up to a whole bunch of hoses. Finally a little box with a couple of regulators can adjust the per patient high and low levels.

This to me seems much simpler and more reliable than ventilators with their own fan. But I don’t have a good way of reaching anyone. I’ve created a thread on my website with my sources, thinking, and some questions. If anyone knows about this please reply here or there and let me know. Thanks.

Because it became, as a descendent of Postscript, a pretty dominant standard for situations where you wanted to specify the layout.

There's certainly a lot of legacy embedded in PDF which doesn't help.

>Is the explanation really as lame as "They were there first and it stuck"?

I'm not sure they were first but they became dominant because... Adobe. And Adobe made it an open standard which pretty sealed the deal.
This also assumes an invariant capacity. Extended period gives us the opportunity increase that capacity through means including getting folks trained as hospital techs (4 week training) and having local teams sew & build our filters and masks.

This is pretty interesting. I've been taking Plaquenil (hydroxochloroquine) regularly for 6 months now to control an auto-immune disease, and I came down with potential symptoms of covid-19 2 weeks ago, but it was very mild - just a sore throat and cough that lasted 4 days, and I had a slight fever the first night. I self quarantined just in case, but after recovering thought I must have just caught a cold, since my symptoms were so mild. But I wonder now if I got it and if taking Plaquenil helped me recover quickly.

Too bad I can't get tested to know for sure :-(

When I started Plaquenil, the doctor told me it takes about a month or two to really build up in the blood stream to help control my condition. I wonder if the need to take it for a while also applies for Covid-19.
The problem is not the CDC developing their own test.

The problem is their banning the use of other tests for months!

The article mentions:

> The clients do not interact with the blockchain directly, so there is no blockchain verification code in the client.

So if all client requests are routed through the same centralized API endpoint before hitting the blockchain, nor validated after the fact, whats the point of the blockchain? Just some public "ledger" of what the server ultimately sends out?

Ideally, at a minimum, you would be given a token for your vote which you can then follow up and see it on the ledger. Even if you don't get to wait for 'confirmation', it's still a public signal that something is not right.
One example that's fun is being able to bring in the data to e.g. Excel - here's an example of a proof of concept we did to give an idea of what's possible with GraphQL https://youtu.be/IHPaDvXQWyA

Building that kind of tooling ad-hoc is going to be so difficult. I suspect that GraphQL is just in the early days of building this tooling, and everyone will be able to re-use it without additional work on their own part.

I think this is true about the SAT but the subject tests are kind of niche and I assume a lot of poor people actually don't know about them. If you're not in an environment where a lot of people are applying to top schools, it's unlikely to be something you are familiar with
I had a bad reaction to Ciprofloxacin. These drugs are poison - they should be an absolute last resort.
I think that it's in the category of soft technical or pop-technical. Similar to something like "Thinking Fast, Thinking Slow," or "How not to be wrong," or even "Mythical Man Month." They're great books to read if you already have some level of technical background to understand the limitations of how they're translating to a more digestible format, but fall into the category of "be afraid of an idiot with a little knowledge" if you don't. Essentially they're wonderful books but can amplify the dunning-kreuger effect.
I'm sure the writers of the SAT are well aware of this, but full IQ tests just don't scale. How are you going to provide the same test ten million times a year, when the test has to be administered one-on-one by a trained professional over the course of hours? You're going to have to hire tens of thousands of administrators, so how are you going to keep bias from creeping in? How are you going to prevent the questions from leaking, or keep people from rehearsing scripts on the subjective parts? IQ tests have never dealt with these problems only because they haven't had to scale, not because they're immune to them.

Chloroquine (not AFAIK hydroxychloroquine) has been made available to doctors (and therefore patients) through "Compassionate Use."

This means that doctors can prescribe chloroquine to patients before and outside of a clinical trial. I suspect many will take the chance.

In effect, the US will be conducting a large-scale, semi-controlled clinical study on a drug with a significant side effect profile in the midst of the worst pandemic in 100 years.

Peter (segment's CEO) had a great answer to this in the thread
https://www.quora.com/What-is-the-advantage-of-using-Segment...

TO summarize and highlight the main reasons

1) With GTM you still have to write code. Specifically, you need to figure out how to send events to a destination following their API and JS library. With Segment and Rudder, you just call a couple of generic functions identify, track, page etc.

2) You often want a copy of the events in your own S3 Or Redshift or Snowflake. GTM doesn't help you there but Rudder/Segment can.

3) We have some features like Replay etc which lets you send historic events to a new destination. Say you signed up for a new Analytics tool and want to send all your historic events - Replay helps there

4) Finally, Segment has this product called personas which lets you create audiences (e.g give me all people who have done X but not Y and then send that to MailChimp for emailing). We too are working on it.

Anyone pitching in seems like they're doing a good thing, but isn't the problem one more of political organization and scaling production?

In other words, the US president (he is the only one authorized to do it) needs to activate the Defense Production Act, and get existing companies to mass produce existing designs. Something similar needs to happen elsewhere. This is a matter of days or weeks, not months.

Exactly. If you look at the comments on the linked article, or the ones that were on top here when I wrote mine, people are making comments that aren't specific to the SAT subject test at all -- "this is great, because I bombed that test", "this lowers stress", "that test was too easy anyway".
