Observations from overseas (Sweden): possibly because college/university is typically (almost) free of cost and because of Sweden's culture of continuous education, there is an increase in university enrollment applications: https://sverigesradio.se/sida/artikel.aspx. I must say that I like that in times of high unemployment, the "free education" feature allows people to further educate themselves when there are little employment opportunities. IMO, this feature takes the risk burden (that the article is mentioning) off the individual.
But if you want to know "what percentage of my population have had coronavirus in each town and age group", then these tests, combined with research to find out the sensitivity and selectivity, will answer that question.

Quite the contrary. The road to the Second World War, at least in Europe, was paved with the good intentions of pacifism and appeasement, and the naïveté of assuming that someone like Hitler could be negotiated with. Britain and France could have chosen not to involve themselves in Hitler’s war (France even tried to make that choice once it started going poorly for them) but that would have done nothing to stop the war from happening. There was a fundamentally irreconcilable difference between Poland and Russia, who wanted to exist, and Germany, who wanted to forcibly depopulate Poland and western Russia and resettle that land with Germans.

I've always thought there should be an "other help" movement alongside "self help."

Some of the content could include guidelines for being available while setting firm boundaries, dealing with caregiver fatigue, setting up healthy habits that loop another person without annoying them.

I would love to offer a couch to a friend in need, if I knew I could count on them not to abuse it, that they'd make steady progress, and that there's a deadline for when we get our lives back to normal. Unfortunately whenever I do try to help out it usually ends up enabling continuing the problematic behavior.
Anybody can make a startup, but it’s incredibly tough to make a successful one, and YC and what PG has built has arguably earned him authority to influence others in this space. And it’s usually pretty objective what constitutes a successful startup.

On the other hand, almost anyone can be a parent, there are many more parents on the planet, and what constitutes an “expert in this space” is incredibly more subjective.

I agree, though, it seems dumb to have governments anywhere near this.
Western countries most likely still aren't testing mild patients.

SK and China went for full containment: every single positive case is hospitalized and close contacts are quarantined in hotels so few cases are missed.

While in New York, hospitals are focused on saving critical patients. If you test positive but have mild symptoms, you are usually let home anyway so it doesn't really make sense to test most people who would be taken very seriously in Asia.
The industry response to GDPR is continually fascinating.

The idea of the GDPR was, presumably, to suggest that publishers and other industry actors might like to change their ways. If they were to keep doing what they had been doing, in terms of personal data collection and sharing, it would require such specific and explicit opt-ins for every single reader that no publisher would think it was a worthwhile tradeoff any more.

But the choice of the publishers has been to do that - to place those specific and explicit opt-ins in front of their readers, to offload to their readers the hard work of changing their ways instead of changing them themselves.
IME, XMPP just works. I recently setup ejabberd+Conversations.im+gajim. There's definitely baggage (the basic idea of routing messages to specific prioritized endpoints, rather than a foundational shared history), but extensions have patched that up to satisfaction. And OMEMO seems to just work.

This doesn't answer your direct question, but does speak to the general "health" of the project. If a project doesn't have much activity, it can be because it simply works to satisfaction rather than being abandoned.

There is a lot of excitement around Matrix, but having evaluated it at the same time as XMPP, I just don't get it. I wanted to like it based on the community excitement, but ended up not. Riot.im on Android is laggy and unresponsive. No feedback when trying to start a chat, then when the server finally caught up hours later, multiple rooms popped up at once. Messages are "sent" with no indication whether that actually happened, and "synchronizing" notifications randomly pop up as if I care. The eventually consistent synchronization layer seems interesting, but without being fleshed out, creates more problems than it solves.

I didn't bother trying a desktop client because the poor flagship phone client was a blocker. Basically the project felt right in line with the poor quality of web apps in general. Perhaps like physical goods, we've collectively forgotten how to build decent software as well, and XMPP is the best we'll have for a long while.

Yeah. Stuff that is written in an affective style drives me crazy. I want to scream "Stop trying to make me feel the emotions, and get to the point already!" I find it rather hard to read.

What's the downside to going to a community college? Where I grew up the credits were transferable.

They did say, "Most people spend the first two years figuring stuff out". I went to college knowing I wanted to study computers, but didn't know what specifically. If I changed fields I'd still have the first 2 years to pay back.

I wish I had gone to a community college first. I overpaid for a worse educational experience. There was too much competition for core classes. So you had to wait semesters to get in. When you did get in the class sizes were much larger. Equivalent, transferrable classes were available, cheaper, and had smaller class sizes at nearby community colleges.

Interview with both! This is a big red flag for both, but issues with the interviewing process don't always mean there are issues within the work place at the company. At worst, you just use the offers from these companies as negotiating tools (as another commenter suggested)--they certainly deserve it.

I would suggest sending an email to company A, worded something like: "I am scheduling on-sites between April xx and yy. Is there a day that would be good for you, or should I remove you from the list of companies I'm considering?"

Fast builds for C++ require unending diligence from day 1. Part of my team’s CI is a build time check. Our code base runs to 10mm lines of code; clean uncached builds are 3m; cached builds are 30s; incremental builds are in the 100s of ms range. The entire system is a single, short Makefile combined with ccache. There’s no fine-grain dependency tracking, so our builds never go wrong.

Until a vaccine is found, 60-70% of the population will need to get infected for "herd immunity". While at the same time making sure infection doesn't grow exponentially, and overwhelms the health system.

Loosening the lockdown, and being prepared to row back, will achieve that if done carefully, while at the same time getting the economy slowly back to normal.

And that probably are a lot more people are already infected without symptoms will help with that.

Trying to somehow contain the infection won't work, because it will just get carried in from the outside again, eventually.

I suppose that the s-curve with 3 parameters that the author is talking about is the logistic function. In general, if you consider a differentiable function of three parameters and try to determine and interval for the values of the parameters of that model then the length of that interval is bound by the ratio of the error in the data over the derivative with respect the parameter. For example estimating the parameter k (wikipedia logistic growth rate) with points such that x near x0 = (wikipedia midpoint of the sigmoid) is hard, since the derivative of the function with respect to k at x=x0 is zero. So mathematically this seems to be a well known fact when one try to estimate parameters from datapoints.

The filters meant for chemical contaminants usually have some kind of active absorber ingredient that get used up which is why the replacement intervals are more defined. With particulate (which includes viruses) the only thing you have to worry about is the filter getting clogged or the filter breaking down due to old age but that isn't going to happen with indoor use unless you are talking years. That's why the filter replacement guidelines seems less specific.

Ask HN: How is your home network configured?

I have tried and sometimes succeeded but often failed to set up a consistent and easy to use home network for all of these devices. Commonly I run into file permission issues when trying to, for instance, create an app in docker on a pi that stores data on a network location (NAS).

What methods do you use in your home network to accomplish file sharing and communication across your devices? What protocols do you prefer and what have you found to provide the best/easiest/most powerful cross-platform network communication and file sharing set up?

(1) Top-Level-Comment-Format:

- IDEA: (One sentence)

- VALUE: (who needs what and why)

- ESTIMATES: Time & Resources

- VALIDATION: How will you know success happened? How would you compare it’s success with prior efforts? How would you know to when to failure happens or related efforts should end? (EDIT: Clarification of meaning “validation” — that being the topic of validation is limited to validation of the “value” not validation of anything else, including but not limited to validation of a given implementation technically, roadmap, etc.)

In my experience Universities seem to actively filter students. Perhaps I didn't reach out (or the University I attended was particularly bad), but I don't remember much support services when I attended.
I imagine reducing the weight of the vehicle would effect it's stopping distance, traction, turning radius, a bunch of other car physics that would in turn produce unreliable data to train on.

I assume much of the training is done in simulation or within a controlled environment but unfortunately the only way to train for city driving is to gather as much real world data as possible and that means "testing in production" with a hopefully alert humans (one for backup) behind the wheel.
Consider applying to a different school, perhaps a state school. A common strategy is to go to a community college for 2 years and then transfer.

Don't most successful people have kids (just like anybody else)?

A large country has a lot of people to test, but also a lot of people to manufacture and perform the tests. So that argument doesn't work for me. Especially when we're talking about the richest country in the world.

Now, if the test making and executing is done by a single centralized organization, it does make some sense. Which is why that way of doing things is an anti-pattern.

> Empirically, people with kids almost never achieve outlier levels of success

I really don't think this is true statistically. Plenty of outliers with kids, as far as kids go.

Moreover, argument is not true, especially for men. Many men leave most of care and career sacrifice on their wifes. They may be slightly inconvenienced by kids here and there, but actually spend equal or even more time in work then before. (Cause home isore boring and wife less friendly now)
The US was disastrous at testing initially, but now they are doing a lot of tests (several million). Unfortunately given the stage they are at (infections widespread, still no national lockdown, some states opening up again because they think it's all over), it's too late for test and trace.

So that is what dart=0 does!

I have Googled this, many times, as with several other weird kernel flags. Not even because I want to fix something, but because I'm curious about what's happening!

Every time, without fail, all I ever find are random forum threads of people saying "this flag fixed my computer", or maybe "You need to enable this flag because it makes your PC act more like a Mac" or some such. It's so frustrating!
The same thing applies to lots of fields of computation. In fluid dynamics, for instance, a direct simulation of the Navier-stokes equations is quite straightforward and will produce the most accurate solution. All the complicated parts are layers and layers of tricks to save large amounts of compute time with (hopefully) negligable effects on the ultimate accuracy.
I got what I still think is the sweetest deal: I was able to take all but one of my classes at community college for my freshman year, while living in the dorms at the state university. It was cheaper to do it that way and the experience was practically the same. In fact, I'm not sure most of my friends even remembered that's what I was doing, since we all had different majors and classes anyway.
Armazi – Wireless Battery Pack, charges faster than regular iPhone charger
This is accounted for in more professional methods which estimate error. During a period of exponential growth, the error 6 weeks out is very sensitive to tiny errors occurring in immediate measurement.

It's not so much that fitting exponential or S-curves is hard as much as even a very good fit is likely to have very significant error bars.

The hard parts about modeling the current situation involve the poor and limited data. The dynamics of the system are highly variable and unobserved and thus require clever tricks to reduce uncertainty by expert knowledge, clever alternative signals, and leveraging other models.

So ultimately, it's just not the forecasting but the response. People rarely handle uncertainty very well and a situation with uncertain exponential growth ends up with exponential uncertainty. Making policy decisions where the predicted outcome spans orders of magnitude is tremendously challenging.

The downside is that you basically won't get into Stanford, MIT, Harvard, Yale... or most any other "top" college after going to community college. I know of one counter example, and I know of many very smart capable people who would have been capable and profited from such a degree, but missed their chance... which in turn made it VERY difficult to get any advanced degree.

Maybe that doesn't matter in CS/programming, but it does in lots of other (e.g. Engineering/Science) disciplines.
