There is already studies on that coming out of Wuhan and it's not looking good. Here are some highlights from my own research. Note that RT-PCR is what the CDC recommends and what most nations are using for testing COVID-19:

> the total positive rate of RT-PCR for throat swab samples was reported to be about 30% to 60% at initial presentation [1]

> In patients with negative RT-PCR results, 75% (308/413) had positive chest CT findings; of 308, 48% were considered as highly likely cases, with 33% as probable cases [2]

> For patients with negative RT-PCR tests, more than 70% had typical CT manifestations. On the one hand, due to the overlap of CT imaging features between COVID-19 and other viral pneumonia, false-positive cases of COVID-19 can be identified on chest CT. Nevertheless, considering the rapidly spreading epidemic of COVID-19, the priority was to identify any suspicious CT case in order to isolate the patients and administer appropriate treatment [3]

> Conclusions: In the close contacts of COVID-19 patients, nearly half or even more of the 'asymptomatic infected individuals' reported in the active nucleic acid test screening might be false positives [4]

Right, that's illegal. Management is under no obligation to accept any particular set of terms, but they're also not allowed to just say "nope"; they're required to continue negotiating with the union until an agreement is reached.
These Are Great Lessons for Life That Anyone Can Learn in Seconds
`using static` goes some way toward simulating free functions in C#.
Fun fact for folks in Seattle, San Diego, Tampa, Washington, D.C., Spokane, etc: Professor Kari Watkins, mentioned in the article, is the co-creator of OneBusAway.

OneBusAway, or OBA, in case you aren't familiar with it, is an open source real time transit information system, and includes a full backend, plus iOS and Android client apps. OBA had belonged to the University of Washington until recently, when it was spun out into a new 501(c)(3) non-profit, called the Open Transit Software Foundation: https://opentransitsoftwarefoundation.org

(n.b. I'm the maintainer of OneBusAway for iOS, and a member of the OTSF board.)
I've written about this previously [0]. There is no shortage of companies with sound products, good teams, and bad management that prioritizes short-sighted thinking in their business strategy. I've definitely seen organizations with senior and staff engineers much more respected than me call out leadership for ignoring critical technical limitations, or failing to prioritize important things, only to lead to bad business decisions that ultimately doomed their companies. Sometimes those at the top don't see big enough of pictures.

I do believe that there's multiple problems that unions can address, and one of which is giving workers more say in how their companies are run and in what they're building.

Obviously, not all management is made up of pointy-headed bosses, and Dilbert shouldn't necessarily lead the company. There are definitely places where engineering-first cultures fail. But the status quo is made up of organizations where employee disagreement is reduced to a few pointed questions and awkward moments at all-hands, and if management fails then those employees are cut and execs get to leave with plushier severance packages. And while unions' primary purpose should be to protect the lower levels of Maslow's hierarchy, they can potentially be a tool to empower employee decision making. Or at least, to provide a check against management unilaterally making decisions even when the rank-and-file disagree.

Sure, you can just say people can leave, or companies with bad management cultures should deserve to fail. But that just seems like defeatism. It seems like a form of capitalism that promotes throwaway, wasteful behavior. If the employees had valid concerns, but management ignored them, doesn't it seem like a shame for an organization to decline and the product to die because of their mistakes. What about the customers?

Even if unions aren't the best tool for this, an industry that's so obsessed with innovation and disruption and experimentation- coming up with schemes like holacracy for instance- should at least try to address this problem. Bring back board-level ombudsmen, at least. [1]

Show HN: DID.app Retire the password, public key authentication for the web
This would still require having the original documentation on how the computer operated. Not to mention, some software (notably some retro console games) rely on quirks or flaws in the silicon itself, and don't actually run on a "perfect" emulator.

If time travel is common and either of these issues is raised then sending someone back to bring the real computer might be the easiest option.
If you ban private companies from making tests, then people like that CEO are blocked from trying.

I just saw that interview with Andy Gavin last week, and I highly recommend it. The title is "How Crash Bandicoot Hacked The Original Playstation" and it truly fits. So much of what they did seems to have been crazy and beautiful performance hacks. Anyone that's had to work with severe limitations to achieve their goal and found crazy ways to make it work will see a kindred spirit.
> Saying that they can become managers is like saying they can become the president of the U.S.

I don't think that analogy is proportional, since that'd make a manager at a furniture store on par with a head of state. But I get it, there isn't unlimited management roles. Because if there were, everyone would be on their own.

If you want to influence and shape business decisions - you want to be a manager.

How do you become one? By showing competence as an employee and joining a lower management position. Successes are how they climb the ladder. Yes, they definitely can innovate, and they can also play it safe.

People in upper management also hop between companies and have similar positions.
I have been using Janus[1] signaling server to broadcast live drone video on my website and it has worked flawlessly with multiple expectators. The drone video is captured through a Janus webrtc library in the Android phone connected to the drone.[3]

With a TURN server from Xirsys[2], I have had live drone video recording as well as barely a second of latency. I disabled peer2peer video because I do not want a 4G connection to broadcast to multiple viewers.

The reason I have not used twilio(even though I evaluated its offerings) is that they do not provide on premises hosting and my potential customers are not normally interested in not having on premises hosting.

I think the question for me (in this thought experiment) will be "what will the code look like if I try to avoid this?". And what are the repercussions? From a performance and/or readability / comprehension standpoint (or any other perspective).
This is the end of an era. I can only imagine what those board meetings are like. If anything like his product reviews, he asked incisive, aggressive questions.

I hope he left because he is satisfied with the job the rest of the board is doing. Yes, Microsoft caused a lot of damage during the monopoly days. The tech industry needs a healthy, competitive Microsoft - at the very least to keep a check on other companies.

> For example, the universality argument also works for the infimum and gcd operations.

I've been thinking about this and I don't see how the argument can possibly work for the infimum operation. The problem is that infimum is necessarily a unary operation -- it doesn't make any sense to consider it to have multiple arguments.

Consider the open interval (1,2). The infimum is 1. But 1 is not contained in the interval. And because 1 is not contained within the interval, _if_ infimum were a binary operation, we could not apply it to the interval and get 1. Binary infimum is the same operation as binary min, and while the infimum of (1,2) is 1, the minimum value of (1,2) does not exist.

We can actually use this to do a much more direct proof of the associativity of binary min: binary min is the same thing as unary min (min as applied to a single set of arguments rather than two scalar arguments), and unary min cannot fail to be associative because it has only one argument. Repeated binary mins do nothing more than apply unary min to the set of individual arguments.
Amazing concept. As an engineering manager, the main cause of my drinking is juniors NOT asking questions either for an immediate blocking issue or for a very clear learning opportunity.

I imagine for many questions are not asked in order to reduce or delay doing actual work. It'll be interesting to see what excuses remain after implementing a solution like this.
I had 7 years of C# experience in 2015 when I had to make an unanticipated job change. With some trepidation, I took a position with another company in the same industry whose codebase was all vb.net. I used Telerik's code converter a lot to bootstrap my proficiency with vb syntax. The boss said I could just write in C# if I wanted to, but I saw no need to make more mental work for the rest of the team.

Absolute value abs(x) using bitwise operators and Boolean logic
Our company, Daily.co (YC W16), makes APIs that compete with these new Twilio offerings. A couple of lines of js code embeds a video call in a web page:

https://docs.daily.co/docs

Our focus has been on doing as much as possible to make video calls reliable, and helping developers get started with video as quickly as possible.

Twilio is a great company. Jitsi is a great open source project. As always, there's room for different approaches to solving hard problems, for different customers. We've found that the biggest pain point for lots of developers are that 1) building out a full video call UI is non-trivial, and 2) handling all the failure cases possible in real-world calls is non-trivial. So we try to solve those two problems.

I love this stuff (this is the third time I've built a video tech stack, in my career), and I'm happy to answer any questions about WebRTC, building live video into applications, and give you (relatively) non-biased advice about tools/approaches for your particular goals.
Here in Denmark we have just shut our borders. You can no longer enter as Swede.

We as nation put on extreme measures but there is no visibility.

What is the true number of infected in Denmark? There is no sampling or systematic measurement going on.

We probably know less than you guys in Sweden yet we choose the most extreme actions.

We just had our PM go on national TV and call on all Danes to return to Denmark as she shut down the border.
I can't edit anymore, but I've thought about this all day, and I think it comes back to trust. It is easy to configure weak keys or keys without passphrases or all sorts of things that you don't want exposed to the internet. Or your server may have poor config so you don't even want people to know that your server exists.

I do wonder, though if it is possible to do use whitelisted features of ssh, like strong keys with strong passphrases, good crypto libraries, etc.

I mean people already type their passwords into a browser.

"The result is, in effect, a map of the magnetization dynamics for seven different time steps evenly spaced over 2 ns, with a temporal resolution of 70 picoseconds and a spatial resolution of 50 nanometres."
But that's the point I'm trying to make - Over my career, I have inherited bad code in both styles - "prefer objects" and "prefer functions". In my experience, bad objects tend to be a nightmare. Bad free functions tend to just be a bit annoying.

There are only two ways in which code review can keep your codebase clean in this situation: Stop doing any other development until it's all nice, or invent time travel.
Show HN: Lighthearted Programming Challenge to Save Tom Hanks from Coronavirus
Oof, where to begin. There are regulations around what states we're allowed to operate in, what kinds of clinicians are able to see patients, how we have to treat patient data, and what the clinical protocols have to look like.

In terms of regulations restricting what we can say publicly, besides FDA regulations around medical claims we're allowed to make, our biggest obstacle is that many of the common channels available to startups for building awareness are restricted or blocked entirely. Facebook and Google, for example, both require LegitScript (https://legitscript.com/) certification. We're in the process of going through that and it may take several months. That's also a requirement for us to be able to do payment processing through services like Stripe, since we qualify as a "high-risk business" since we do both telemedicine and addiction-recovery services.

But even when we do have those certifications, Google, Facebook, Reddit, and many other sites have a blanket ban against targeting users who are part of addiction and addiction-recovery groups.

It's not that we can't comply with any of these regulations (and in fact, we're working on many of them as we speak), but many of them are really onerous and time consuming for a startup given the stage that we're at.
We're a startup that makes a video API that competes with Twilio. I can tell you that we're seeing a big increase in interest this week from both big companies and startups, across a big range of use cases. (Lots of telehealth and online education. Also lots of cool "distributed teams" experiments.)

I want to repeat what I've said in other comments, because what I initially said was inaccurate. These researchers didn't actually create a new coronavirus, but rather a much simpler and safer virus purpose-built to test some receptor-binding structures. This is a well-established way to study viruses safely.

This kind of work is critical if we're to learn how to develop vaccines faster in response to epidemics.

Joel talking about the great care they took to build their offices (in a way that I felt was a huge mistake) was sort of the beginning of me realizing that he doesn't get everything right.

There's also an uncanny valley effect, where ignoring a problem entirely means that your employees may have needs they aren't aware of, and as soon as you shine a light on it, their job satisfaction is actually lower until you get it right.

I think a couple of my bosses understood this intuitively and would invite us to participate in developing solutions. We are much more patient with ourselves than with others.
There are test kits in the UK, but the same policy applies.

Why?

Because it no longer matters, the containment effort for individual cases is now over. Now we move on to more mass actions to delay and slow the peak of the epidemic - anyone with symptoms to self isolate for a week, regardless of positive test.
The only problem is that Powershell as language is pretty bad. I wouldn’t want to write my vB6 projects in Powershell.
What do I need to know about the coronavirus?
> There's a problem, though: we're restricted by regulations from letting people know that this treatment is available. Both Facebook and Google require a third-party certification before allowing us to use their platforms, and many sites like Reddit don't allow any advertising for addiction treatment at all.

When you say "regulations" here, do you mean government law, or just the rules of online services as in your examples?

To advertise to addicts, go where the addicts are; bulletin boards in halfway houses, homeless shelters, probation/parole offices, and clinics that offer court-mandated treatment programs. Granted, these are the places where the most down-on-their-luck addicts will be, but perhaps they will be more open to change than the "successful" ones. That said, you might have some luck targeting those types on web forums for drug addicts and experimenters - some of these use their own in-house ad systems rather than something like AdSense for obvious reasons.

(If it sounds like I might know some things about where you can find drug addicts… well…)

I wish you nothing but the best of luck with your project.

I'm sure in general Microsoft would love to scrap VB in Excel but there's too many companies that run entire areas of business on it, or the whole business itself.
