The core of our machine learning is Ax=b :grins:

More seriously, the main reason why traditional sanger sequencing can't be used for COVID-19 testing is because it would be unclear whether a lack of signal is truly due to lack of virus, or if it is just because the assay failed (happens all the time!)

What we've done is introduce a reference sequencing signal that is biochemically very similar to viral RNA, but produces a distinct vector of electrical signals that is different from the signals emitted by viral RNA. Since we know what both the reference and viral signals look like, we can perform linear regression analysis to fit the linear combination of viral and reference signals that best match our data.
Gosh OData is so poorly designed that the only way something like that can even think that it is relevant is if one or two paper pushers inside a big corporate company will force its devs to use it. And so they did.
A free Covid-19 Symptoms tracker
When I first heard of microservices, it confused the hell out of me when I tried to define my company's code base. In some ways we had microservices, for other applications or features we were working on a monolithic service. I used to think it was my lack of understanding, but I eventually realized our code didn't have a binary definition that all the blog posts I was reading seemed to apply to.

I feel like we should have been using verbs this whole time. At least when applying it to legacy systems. Similar to say for databases we can normalize data, or denormalize data. Is there a verb for this already?
Develop a Passion for Tech
This is awesome. Thank you for all your work.

One million a day seems like a lot until you realize it would take about a year to test everyone in the US... How can we increase this to 10m per day? Is that possible?
Hey Guys.

I work as a developer for this company. We are based in Australia. It is a free to use Covid Symptoms tracker that you can use to daily track your symptoms.

Even if you are healthy, would be useful to track your progress throughout this quarantine period.

It also has a delete my profile option so you can leave the platform anytime you want and all the data will be wiped off.

Just need your email to sign up and I promise we are not spammers :) .. This is just a way for us to open up our platform to the public to use.

Would love to hear your feedback on the same too.

Stay safe everyone!
You know something about this specific case. I do not. I hope you land the kind of role you want, if you dont already have it yet.
Yes, which is why a better serological test would be extremely useful, the sooner the better. In no way does this undermine the value of BillionToOne’s test, but it is irresponsible for their CEO to be saying that serological tests are not useful yet when they are.
Hi sneak,

The address bar looks horrible when selected [0], it outgrows its container and invades the space of tabs. I thought it was a bug at first, but it's probably intentional. is there a way to go back to the normal address bar?

Ok, this IS stepping up. 1B will make a difference.

The big problem is that if distribution is not properly managed it will go to waste via people taking advantage of the situation. Giving away money responsibly is hard. We see it all the time.
Because scaling medical testing is the same as scaling web services...
They were privatized (formerly funded with toll bridge dollars), had service cut, and roundly failed to make a profit and are probably being transferred to another company. My point was that privatization is not some golden age all these services started out with like in WA.
I don't think we are in any way undervaluing the serological tests. A great serological test would be very useful. However, because of the indirect measurement, they tend not to be very sensitive or specific, so it is fair to say that they become more important not at the peak of the pandemic but at the post-pandemic period.

By the way, as a company, we really don't have much to gain from this test. If it does not get adopted, we'll go back to building our core business which has been growing 100% quarter over quarter. We have poured resources into the current development, because it is the right thing to do. No investor in our Series B round will take into account any non-recurring sell-almost-at-cost revenues that we get from a once-in-a-century pandemic.
Almost all workers in America have rarely if ever seen a “bonus”. They airline execs will get over it.
It's true that there are some loopholes [1]. It's also true that as a permanent resident, you come under the category "US person", which some/most of the ITER law refers to, which restricts non US-persons from working with "Spacecraft Systems and Associated Equipment" [2].

But I think it's fair summary to say that if you are neither a citizen or a permanent resident, you have a damn tough hill to climb [3].

Product Roadmap Detours
Let different people deal with the situation in their ways without playing the mighty judge who owns the "one right answer".
This would be HUGE. Not only has the testing capacity in America been maxed out, but the % of positive results has been more than 20% and trending upward. In order to quarantine effectively (read: end the shut down) we need to test the family, coworkers, and contacts of every positive result.
I hear that. I worked at a place in the early 90s that had a product to port System/36 based RPG II code onto newer platforms. It kept 4 of us pretty busy, and RPG is just a small language doing flat files on a mini with a simple scripting language (OCL = operation control language) and job queue system.

Later we took on the AS/400 version, but I left before that product went live.

A Landscape for Learning Japanese
A lot of books mentioned in the comments are great. But reading them just to read them isn't going to bring that much value. I get the most value out of programming books when I've been coding and I see place in my project and I think, "there has got to be a better way to do that." I then will search for specific chapters in books that help me improve what I think can be done better. To me it's better to use them as a reference while you are building something than just reading them cover to cover.
I know a company that did. Amazon was 30% cheaper than heavily discount UPS rates. Sometimes, they were even cheaper than the USPS!
That's the difference between "the business" being tech, vs everything else.

Kind of hard to lock down everything to personal environments, when the majority of the company are developers!
It looks like David answered that here: https://news.ycombinator.com/item?id=22808525. I agree that it's better not to use buzzwords, and have edited the top text to say "linear regression" instead of "machine learning".

(This is actually part of the standard advice we give to YC startups who are launching on HN: don't talk like you would to investors—talk as you do to fellow implementors.)
I'd say it only requires you to keep in mind "crap, that's right, I installed another `sc`, the one I want is `,sc` now", and only for the few name collisions you have to deal with.

>Rather than requesting bailouts and rule changes, imo they should be selling that stock to raise capital.

This strategy has already been kneecapped by plummeting share prices, and trying to sell massive amounts of shares right now would only lead to even further diminishing marginal returns.

Airlines are a crucial national infrastructure, and they know this, which is why they've been incentivized not to give a shit about recession resistance. Bailouts are fine, as long as they are coupled with corrective action. Those who accept them should be unable to buy back stock in the future, and required to build up the capital reserves necessary to weather another pandemic.
Clickstream Analysis – An Open Source Architecture
They get basically two superimposed chromatograms from Sanger sequencing, one from the control and one from the patient sample. They need to sort out which chromatogram peak belongs to which and calculate the relative abundance of the sequences in the sample from the relative peak intensities.

The machine learning angle isn't the exciting part here, it's all the rest. Great idea!
> Models in general haven't overpredicted warming

Yes, they have. We're obviously not going to agree on this point.

> It looks like you're arguing that because something is changing over the course of several decades it's not as much as a problem.

No, I'm arguing that the problem is not new, and it's not a climate problem. It's a problem of misgovernment and has been around for quite a while. But that doesn't stop cities and countries to try to get the rest of us to pay for fixing it by trying to claim that it's a cimate problem.

> The climate is changing faster by far than it has in all human history, and probably in the history of our planet.

This is ludicrous. Nobody has the data to back this up, and there is plenty of data contradicting it.

> When you have 7 or 8 billion people living on the planet, largely in huge cities, it's far more challenging.

When the "problem" you're talking about is a degree of so of temperature rise and a foot or two of sea level rise over the course of a century, to call dealing with it "challenging" is an egregious misuse of language. This is simply not that big a deal compared to all the other things we humans have to deal with. And the things we will need to do anyway to deal with those far more challenging problems--like how to bring billions of people out of poverty and how to make our infrastructure more robust--will end up adapting us to the change anyway. If we're going to spend trillions of dollars on something, let's at least spend it on something that benefits everybody regardless of what happens with the climate, instead of on a huge CO2 mitigation boondoggle that will transfer a lot of money from your and my pockets to the pockets of politicians and "green" business executives, but won't actually help much of anything.

Scaling a static website involves far less technical knowledge than scaling a high politics / moderate complexity scientific process.

The website looks terribly designed from a scaling standpoint. Have you run even a basic google pagespeed on it? Why no cache TTL on the custom TrueType font? Why no CDN backing?

This is a bit random, but if you have a "proud" web developer who "knows best" find someone with no pride who can get this sort of thing done.

We believe google can scale in part because they seem to be able return web search / autocomplate / google assistant responses pretty quickly.
And it's not like this is totally unprecedented. That's exactly what we did with banks in 2008.
Take a look at the size of the losses the ferries run at.

The government forced the private ones out of business by setting fares, rates, schedules, routes and pay. It didn't add up.

I imagine Church never dreamed that his approach of unitary type assignment would lead people to believe that types actually exist, and that programs should do different things when meeting such 'types'.

Yes let's get back to Curry, and build a better world.
Your memory is highly selective and simply wrong.

On Dec 31, China informed WHO about a mysterious cluster of respiratory ailments clustered around a seafood market in Wuhan. China didn't even close the seafood restaurant until 2020. The first confirmed death wasn't reported until January 11. China didn't begin a lockdown of Wuhan until January 23.

Yes, the CDC dropped the ball, but evidence coming out in March indicates that China knew about COVID19 in early December and didn't bother to tell the rest of the world about it for another month, and even then downplayed the seriousness of the virus until the end of January.

To this day China is still blocking the release of information about the severity of COVID19. WaPo reported last week that there may have been more than 40,000 COVID19 fatalities in Wuhan alone (based on manually counting the number of urns distributed by morticians) which is at more than 13x the official number of deaths reported for the entire country.

Things I've seen that seemed to contribute to team happiness and productivity:

1) Process-focus. It's not "stop doing that, Bob", it's "let's make sure that can't happen unless we really, really want it to". And not just for technical stuff.

2) But also a willingness to kill processes if they weren't useful. Always OK to ask "who needs this meeting?" or, understanding its purpose, "can this be a few 10-second Slacks with follow-up when necessary, instead of a 15-minute team meeting every day?"

3) Project managers who were "on the team's side", at least so far as the team could tell. You come in taking the whip to people, you end up with bullshit information. You can't manage a project effectively with bad info. You want your team to tell you when shit's going sideways, or just that it might, early. They won't do that if they think they're taking on personal risk by raising issues. And they'll be stressed out and their work will be worse.

4) Semi-relatedly, estimation based on past (team) performance, on the same project. No guess-timates becoming commitments. No "so, can you have that tomorrow? Two days?" This is one part of the "agile" thing that, when done right, I've not seen anything surpass in accuracy or in keeping panic and confusion away. It does mean your estimates at the start of a project can't usefully go very far into the future and will best be expressed as large ranges until at least a few weeks in, and that you can't swap people around all the time and keep estimating accurately—but that's true anyway, even if you pretend it's not. I have seen people care a lot that their estimates often suck but not be willing to give up the "so, one day? Two days?" ambushes or accept that there will be times in a project when responsible estimation is very imprecise. These folks tend to get bad info on top of the inherent flaws in their approaches, because they have trouble with #3.

5) No "I have five bosses" crap.

That all may be more "in the weeds" and/or obvious than what you wanted, though.
How surgical masks are made and how to test their quality [video]
The GP wasn't necessarily a helpful comment, but please don't respond by being snarky. It just makes the thread worse for everyone, and you can make your substantive point (the distinction between those kinds of scaling) without it.
I would like to echo the concerns about academic integrity. For example, at Cornell, it is not permitted to get help from anyone but course staff on assignments in the intro CS class (and many others): https://www.cs.cornell.edu/courses/cs1110/2020sp/policies/cs...

I guess this could still be useful for help with concepts/exam prep, but not sure how much traction that would gain as people tend to be busy with the projects.
Because "screw sick boys!"

This normalized and applauded sexism in "aid" is disgusting.
Seems exploitative - Angelinos aren't hurting for work right now, they're hurting for a paycheck. I'd like to see some kind of compensation model.
Yup. A lot of Youtube abuse starts with hijacking.

Lots of popular Youtube channels are by people who aren't very technically savvy. You can easily have 10 000 subscribers while only barely following how to make a video and upload it if there are 10 000 people out there who want that particular niche content. 100 000 is less common but not rare.

That's a juicy target for a hijacker. The hijacker tricks the channel owner into giving them control. "Hi, YouTube Services here, great to see you're so successful. Can you go fill out this form and we'll upgrade you to Elite status". A day later, locked out of their account and unsure what's happening, the channel owner is frantic. If they're lucky they know other Youtubers and can get control back. Otherwise... they may just walk away.

Meanwhile their subscribers are surprised to find that they're now subscribed to "Crypto investor update" or "Apple Genuis Bar" or whatever and it's bombarding them with videos they don't want.

Every feature you give the channel is a feature hijackers will try to use to maximise their profitability. If they can replace old videos, they will, if they can edit them, they will. They can change titles and hide stuff so they do that immediately.

If you're a channel owner: Buy two FIDO Security Keys. Use them to secure any accounts related to the channel then put one somewhere safe (maybe literally a safe if you have one) and keep the other like your house keys. Unlike other 2FA technologies, FIDO keys can't be phished. So short of you being dumb enough to literally Fedex your key to a bad guy (Do I need to say not to do that? Do not do that) there's no way to get tricked into letting them control your channel.

But until we get to a world where this sort of defence is ubiquitous, every Youtube API feature has to be considered as to how you'll unwind it if the channel was hijacked.

Even a 'month before' some unforeseen event, it's not a 'special win'. It's barely a special win in any event.
>The worst cases I have seen is when executives take a problem and ask data scientists to "do some of that data science" on the problem...high-level pie in the sky stuff that works well in pitch meetings and client meetings...

I'm been in various external and internal facing Data Science roles for 8+ years and this is spot on. IME it's the #1 reason Data Science projects "fail." If you can replace "do some of that data science" with "do some of that black magic" that probably means nobody actually checked to make sure the data and problem made sense in the first place. But somebody somewhere already committed to it, so the Data Science team has to deliver it.

>So by that logic a data scientist should be a person who uses the scientific method to do research on data. Does that make any sense? And let's be serious, is that what most data scientists are being hired to do?

I certainly do, but I've been doing data science for the better half of a decade. It seems starting around 2015 when Data Science became a sexy title, a lot of fresh blood has been overgrown software engineers wanting the title, not knowing what they're getting into, or having faulty expectations. I don't consider this class of "data scientist" a data scientist, which is why the community has started shifting its job title away from Data Science to Research Scientist to better differentiate.

The good side of this is I'll come into a company with them expecting me to be like an over blown software engineer, and it gives me the opportunity to show off and go above and beyond what companies expect, allowing me to come off like a super hero. Though, it's definitely an uphill battle, and knowing how to work with upper management is an absolute necessity.

actually, scaling a website is much easier than scaling a medical service.

If you can't be bothered to take some basic steps for web site scaling (google page speed + a CDN) then the idea that you will carefully and successfully navigate to a 1 million tests per day moderate to high complexity medical test seems like it will be a stretch no?

That said, a 100% support MUCh higher test capacity, both this and IGg IGm (which should allow for home testing). So good luck!
Might this explain the poor survival rate?
I doubt anyone is using Edge enough to find out. Generally now people are trained to Chrome regardless (most people home and work), and w/the IE Tab extension there is no motivation to investigate.

As a side note, I would guess most non-GSuite users are logging into their Google account on Chrome and getting a unifed bookmark, whereas if they sign into a MS account at work/Edge, it will have to be their work Office365 account, breaking their unified browsing experience.
My hesitation is how do you know where the money is really going? For example the $100k he gave to America's Food Fund, how do they prove only going to people affected by Covid19? Call me cynical and a skeptic, but I've personally witnessed people trying to benefit from programs and non-profits that don't need the assistance. There are shady and scammy individuals out there.
I wouldn't say it's the opposite. It sounds the opposite from the title, but this actually returns Wikipedia content. The other one fetches a link to a site.
You can't refactor any implementation (i.e. shuffle code) into components and magically make verification tractable. But there's more than one possible implementation to any particular functional problem, and some of those implementations might be tractable.

AFAIU Component-Based Software Engineering has been a bedrock principle of applied formal verification for decades. It's a process approach. If a functional problem is sufficiently complex it's necessary, if not always sufficient, as a practical matter to use a component architecture. And even if it's not sufficient, a solution where some components are formally verified is better than where none are. Circumscribing soundness isn't an alternative, it's complementary.

You're right, it's not by itself a "solution" in the sense of completely resolving the problem; it's a "solution" in the other meaning of that word--a means of dealing with a problem.
I've never seen a userdir URL being used with anything but raw static HTML with no or little JS. Generally the type of people who use these hosts don't use cookies or local storage at all. They just want to post a few web pages, photos, or documents. Can someone find an example?
Close enough. I work for a 'body shop' and I'm currently working for a european government client.
A patently bad argument. No company was forecasting a pandemic in their 5-year plan. Doesn’t mean American or any other firm should receive special treatment.

American Airlines alone has a market cap today of $4.7B.
