Now that's an interesting question - does Google combine data from GA into their other tracking, or does that data stay separate?

I think what parent means is that Intel can do it to AMD over x86 chips and nVidia can do it over GPUs, where they have a lead in several market segments.
> Many observers, and many investors, believe that young people are especially likely to produce the most successful new firms. We use administrative data at the U.S. Census Bureau to study the ages of founders of growth-oriented start-ups in the past decade. Our primary finding is that successful entrepreneurs are middle-aged, not young. The mean founder age for the 1 in 1,000 fastest growing new ventures is 45.0. The findings are broadly similar when considering high-technology sectors, entrepreneurial hubs, and successful firm exits. Prior experience in the specific industry predicts much greater rates of entrepreneurial success. These findings strongly reject common hypotheses that emphasize youth as a key trait of successful entrepreneurs.
ssshhhhh. Don't give people ideas
Use it quite often and enjoy it. Biggest reason is because I love C#/.net. Only recently been using Xamarin.Forms, which seems to finally be getting to a pretty mature state. They’ve made it a lot easier to jump in/out of Xamarin.Forms and Xamarin native within the same app. Also recently added Hot-reload features to compete with flutter.
However, Flutter feels like it’s ultimately going to take over this space for “native” cross platform development. More momentum and less baggage. I have noticed Xamarin seems to be better about incorporating community feedback since flutter became its primary competition. Flex layout, Shell/route based navigation, etc. seem like responses to flutter features. Xamarin is great for C# fans but probably won’t win over many others outside of that with flutter as the alternative.
In fact the first symptomatic case in Wuhan was identified on Dec 1, and by Jan 16 there were 41 cases of pneumonia identified. That is about the same span of time as between the end of winter break and today. And Wuhan is a dense city of 11 million while I live in a relatively sprawling American city of < 2 million with essentially nonexistent public transit, so transmission could be slower.

Alos, I don't know what typical air quality is like in Wuhan in the winter, but given what I've heard about Chinese cities, more severe impact of respiratory symptoms in China seems plausible too.

In any case, I agree that there's a fair amount of uncertainty, but a verdict of "certainly not" seems unwarranted.
It would be better if they communicated that people shouldn't worry about getting or wearing masks because most people don't need them, and they are needed by people who do need them.

Also, it is helpful to keep in mind the distinction between surgical masks and N95 respirators. The latter are effective at preventing transmission if worn properly. They should be saved for use by health care workers and those caring for sick people. Which means shouldn't worry about buying them at the exorbitant prices, and should probably save for (or give away) when needed.

Surgical masks are helpful for sick people to wear. For prevention, they help a little so worth wearing if have them but not worth panic buying them. And keep in mind that hand washing and other things are more effective and important prevention.
Confluence, or a similar private wiki is a good idea. As you work, write down steps to do things that were essential to doing part of your work, or things that you will need to repeat often.

E.g. Create tutorials on setting up a development environment, installing dependencies, compiling modules, running tests, creating new components. Write descriptions at a high level of the system, make diagrams of complex message exchanges. Write down best practices, or paste boiler plate code for doing specific useful things.
I'm talking about public companies that are listed on the exchange, private companies don't have a federal mandate to follow when it comes to governance.
Don't assume that the architecture is even there for the institution to have control over everything. Small, young organizations are often relying on things they aren't fully aware of, like so-and-so has an uncle or a trust fund or a fast car or something.

When you talk to the outgoing employees, ask yourself if the processes they are describing are even processes that are replicable or controllable by the organization.

So, for example, are people putting things on their own credit card and getting reimbursed? Is this potentially a problem? Do you need to arrange a company credit card so the organization has real control here?

Then you need to document things. But don't just assume that the architecture is even there for the institution to be in control. You may need to create that piece as people leave.
Sure, but I trust GPG. Has age been audited? Has it been attacked in the wild and held?
But China shows us you can't just extrapolate the exponential curve. As cases grow there will be a response and China shows us (if you trust the numbers) the response makes a big difference. There may be a short term exponential growth but with contact tracing and various quarantine measures that curve may decay (e.g. many of the contacts may catch the virus, their families might, but the following transmission could be reduced).

I actually stocked up (we always have lots of bulk dry foods anyways) so I can stay home if needed but there's really no clear picture of what's going on.

If there is widespread transmission coming from asymptomatic people that would mean this is a lot less dangerous than people think, maybe all these people coughing in the office actually have covid19... If there isn't than why worry yet. There is some evidence that suggests this doesn't transmit very well (e.g. many people quarantined through close contact tracing did not catch the virus) yet there is some contradictory evidence (e.g. the cruise ship or larger clusters.). The truth is probably somewhere in the middle.

If you live in an urban area with millions of people what would be a reasonable threshold of cases to isolate yourself completely?

My feel is that it's worthwhile being cautions and also assuming the actual numbers are ahead of the curve we see. As long as the projected numbers are still small relative to the overall population then washing your hands, being careful what you touch (your face and shared surfaces), and reducing unnecessary close contacts with random people are likely good enough safety measures.

As the numbers grow you can consider completely eliminating contact with others though that can be pretty difficult.
A few key technicians catching it (or refusing to show up to work) could easily disrupt a city's (or at least part of a city's) water system.

Of course, that's the case with seasonal flu as well, which is why it's a good idea to keep water on-hand to start with.
Perhaps it would help to give a longer example for the parent. For many complex systems and differential equations, modern solution techniques such as finite element, finite difference, and finite volume methods provide superior performance and model fidelity. Many equations such as those for fluid dynamics can not be solved analytically and must be solved using a numerical method.

Now, if a differential equation is linear, after discretization, it can essentially be boiled down to a linear system such as Ax=b. The dynamics can be found in the linear operator A and the forcing term is b. We're interested in x. As such, we seek something akin to x = inv(A)b. If A is a matrix, we may invert it. If we have a time dependent problem, we essentially find this using a time integrator such as a Runge-Kutta method.

If the differential equation is non-linear, we have a nonlinear system of the form F(x) = b where F is a nonlinear operator. In order to solve this, we typically apply some kind of Newton type method, which is really just truncating a Taylor series and solving for x repeatedly. Namely, F(x+dx) ~= F(x) + F'(x)dx. If we want F(x+dx) to be 0, we then have an iteration F'(x)dx = -F(x) where we solve for dx. The term F'(x) is the total or Frechet derivative and is a linear operator, so we're back to what we did before on a linear system above. However, the question is how do we find F'(x)? We can do this by hand, but it can be laborious and error prone to do so. Alternatively, we can use automatic differentiation to find this operator. One algorithm in the collection of automatic differentiation methods is the complex-step differentiation. Other methods include things such as forward and reverse mode.

Outside of differential equations, optimization algorithms require the gradient and Hessian-vector product to compute effectively. Automatic differentiation can find these quantities as well. In fact, back propogation in machine learning is the combination of steepest descent with the reverse mode automatic differentiation algorithm.

Anyway, there a lot of different applications. These are just a few. Personally, I think there are better algorithms that the one presented in the paper, but it is important for historical purposes.

And, to be sure, perhaps you already know this and if so, I do apologize. Mostly, I think there's some confusion as to how and why we use these methods, so it helps to give some background to others who use this board as well.
Influenza and COVID-19 aren't related, but the overall infection math works similarly. They are most closely modeled by a differential equation that has a carrying capacity that moves based on many factors. Their main commonality is they are both highly infectious.

Different parts of the world are at different phases of the situation. The US is currently at the recognition phase, and it's difficult to tell, without additional cases, the estimated time until acceleration. [0]

Sarcasm is writing the opposite of what you mean. It doesn't work in short form text (similar to Poe's Law) but people do it anyway because it works in their internal monologue that has vocal intonation. Even when it works, it's an obnoxious outburst and intellectually devoid of value.

I thought electricity was something I could rely on having in my house unless a major catastrophic event happened, in which case I'd have more to worry about than just electricity.

For the past year or so, my electricity goes out at least half a day every 2-3 weeks. Once, it was out from the moment I woke on a Saturday at 7am until 3-4pm or so. I live in the Mission, San Francisco. Sometimes I get a heads up by text from PG&E a few hours before, sometimes not.

My gut wants to agree with what you wrote, but I feel like re-evaluating my priors is appropriate here.
Do you know how to make a mask? Perhaps then those who can make the mask by themself can have a mask even if the store doesn't sell it.

YAML, hjson and jsonnet do not validate existing json blobs. You can "use" ROT13 for the same purpose, but it's incidental in what you are trying to do.

I would plead that everyone stop using YAML. It's terrible at everything.

jsonnet is a template language for a serialization format. Who would choose that nightmare?

Ecmascript isn't big on extending the language orthogonally, so hjson is eventually going to be superceded by a ES*.

This is a niche concern that has an optimal path. Go with a validation schema designed for applying to a serialization format, which has widespread library support.

Sure, but the whole point of this article was that the telemetry data is also biased.

There is no magic bullet. Your options are to get biased data the cheap way or the ethical way. Either way, the data is biased and you have to consider that when making decisions.
You believe the US won?

1. Working in pairs or teams. Avoid solo people working on projects.

2. Common, easily searchable place to put all documentation at. Good search capability is critical. Wiki is ok.

3. A good code & commit search engine. Ability to search code reliably obviates the need for a lot of documentation.

4. Weekly knowledge sharing sessions with the whole team. Both presenters and question askers need to be rewarded to keep engagement.

It is like replication in distributed systems. There are varying levels of redundancy you can get, and each higher levels involves higher overhead than the previous, so there is no golden rule - it needs to evolve as the organization evolves. A startup might have many people who are the only people who know certain things, but a 10000-person company surely should not have any institutional knowledge bound to one person.

I'm not seeing smoke.

I see a low mortality rate for healthy people.

https://www.worldometers.info/coronavirus/coronavirus-age-se...

I see stories about how the virus is circulating because most people have no symptoms, and don't even go to the hospital.

https://www.thelocal.it/20200228/coronavirus-may-have-circul...

The only firsthand account I've read makes it sound like a cold. "If I were at home with similar symptoms, I probably would have gone to work as usual."

https://www.nzherald.co.nz/opinion/news/article.cfm?c_id=466...

Yes, wash your hands. Yes, don't go to work with a cold. Yes, older and sick people may want to self-quarantine. Sure, buy some extra food. No, don't spread panic.
It just means people leaving are not that critical. If they were, you would have that documentation or you would be SOL pretty often.
Can't they just skin the app and license it to these companies?

They just need an enterprise account for each company (or police force or whatever) to distribute the app internally. If anything this just enables them to charge more assuming they've proven out the capabilities and the ROI.

Then each company can distribute it as their own app internally - all within the guidelines of the enterprise TOS.

If just skinning it isn't enough then they can create an SDK and have then consult each company to develop its own app that uses this SDK as part of it. It isn't like Apple restricts enterprise app from using other services and APIs within their own apps.

I don't think the TOS are particularly unfair or hard to work within in this case.
It runs in my family, I don't have it. Gluten free food was pretty rare even ten years ago but it's pretty good now where I am (in the UK). It costs more but not a huge amount more.

Some things that come to mind:

* Ring up restaurants ahead of time and ask if they can cater for you - they often can (Where I am at least).

* Gluten free cakes can be quite bad - they usually taste fine but the lack of gluten makes them fall apart: if you like baking it's worth experimenting with alternatives to gluten.

* Some people assume that it just means you can't have gluten (a la a mild allergy), so emphasis that it is a serious disease ("No more Gran " was what I was told when she was diagnosed (at 70something!))

>>If it were truly an existential threat the US would remove the Taliban very quickly (that doesn't imply a safe orderly society would result).

With what, nukes? Or by sending 5 million soldiers using $400/gallon gasoline https://www.cbsnews.com/news/real-cost-of-gas-at-afghan-base... ? Like them or not, the Taliban are in their country and quite a few Afghani think like them. Let them be, with a major caveat--do not let anyone there attack us or our partners. I think they are rational enough to do that since USA did cause them a lot of problems.

They are so many problems in the world, USA cannot fix them. Not even make a dent.
You seem to be assuming that the differences don't have a rational basis. Cars are generally homologated for a large geographic area, which might include Arizona even if the car is sold in Canada. Towing limit standards may also be defined differently in law.

Hypothetically the regulations might specify that the vehicle must be capable of safely towing the stated load without overheating at X incline at Y speed for Z time at A altitude, be able to stop in B meters, plus C overall safety margin. It's entirely reasonable and rational that the values of X, Y, Z, A, B and C might be different in Europe and North America.

I was rather more negative about libertarianism than I was about liberalism, if you read carefully. I'm not a libertarian, but I do see the movement as a more meaningful criticism of modern politics than whatever the "right" is up to.

I have a book covering, among other things, Indiana time zones for a few years during IIRC the 1960s.

It’s frankly amazing how much they changed every year. Different counties, and sometimes towns/cities within counties, would jump back and forth year to year. It would have been awful to manage if computers had been more important at that time.
I don't think this is as useful as it might seem. Significant respiratory impairment may occur before a drop in oxygen saturation, expecially in the young and healthy. I would not be reassured by an oxygen saturation reading if there are other signs of illness. Adequate clinical assessment of a suspected severe respiratory illness comprises multiple factors of which oxygen saturation is only one.
+1. Atlassian tools catch some flack (for good reason), but I worked at a company where anytime someone had a question that their immediate neighbor couldn’t answer, the response was “try checking Confluence, I usually find stuff there”.

Yep. They're only breaking into the main page a couple times a month. Still surprises me.

we've come a long way from "failure is not an option".

this is typical musk spin. of course we can't be afraid to fail, but that isn't what happened here. catastrophic failures should not be considered "oh well" situations. move fast and break things isn't a design and engineering approach worth subscribing to. i'd appreciate a more measured response from spaceX. the quote "Not much to worry about here" from spaceX is pretty annoying. a less dismissive tone would be better, because from my point of view, they just had a pretty large and expensive failure. that's bothersome from someone getting a ton of public funding.

a response of "we take failures very seriously" rather than basically "yea, that'll happen" would be more professional.
I do wonder whether the fact that some systems aren’t really 4-digit-year compliant is making this uglier this year. I know Splunk got hit with a 2020 bug.

That article doesn't seem to support "because they were malnourished" at all... it correctly points out that the 1918 pandemic was unique in having high mortality among the young (under 30) due to "Lack of pre-existing virus-specific and/or cross-reactive antibodies and cellular immunity in children and young adults" which doesn't seem to be the case with the current virus which seems to affect mainly the elderly.
