Yes, that matches the WHO stuff I linked and contradicts Chuck's opinion about asymptomatic infections.

For instance, it says:

Estimates are ~80% of infections non-severe, including asymptomatic infection likely.

The language there doesn't separate the asymptomatic infections from the disease.
Thank you! I cannot count the number of times I have had a CMake problem and had the usual inclination to try to understand the framework behind it, only to be stonewalled by the seemlingly complete lack of context in the documentation. I have given up on it time and time again. Somehow my project manages to barely get over every CMake hurdle but I still dream about the day when I would actually understand it, and have the same feeling of control that I usually strive for.
For the part I have used, it is a common API over various solvers (free and commercial), plus some google own solvers. It is pretty neat, but because of licensing reasons requires you to recompile it yourself to access all the free solvers.
Here's something I haven't seen mentioned and long term it makes a huge difference:

If so far you used public transportation to get to work or just walked and otherwise didn't do any exercise - start. 30 minutes of mild yoga is enough.

Remote work often comes with a double whammy of less exercise and increased snacking - both will make you put on weight.

I've put on 15kg over the four years I've worked remotely and now after two months of office work already lost 4kg, because there's this hill(20m height) I have to descend every day to get to work.

You keeping your balance in the bus every day really adds up over time.
The issue is that the solution to errors like these is often not adding a semicolon, but something else like “the compiler has no idea what is going on in this line” and the actual problem can range from something like an unbalanced delimiter, a misspelled keyword, or even a “syntactically valid-looking” (that a stupid parser, like a code highlighter or formatter, would approve of) but ultimately subtly illegal construct. With practice is usually becomes fairly easy to figure out where the actual error is, but it’s certainly not a very good experience for beginners. (And they’ll “come to hate it” because they’ll see it more than a few times before understanding how to deal with them.)
The reason it is not used in fintech is that it is extremely complex.

The greatest failing of wireshark et al today is not understanding lz4 and zstd compression.
It costs like $3k to save a human life and we still go on vacations to exotic locations and drive $50k cars. It's not that dairy milk is so very good, it's that we care about suffering so very little. You're the minority with a disproportionately sized well of empathy is what's going on. Any attempt to understand it beyond realising that when you go out and about every day you're largely surrounded by monsters is just going to lead to confusion.
Thanks for the explanation. Makes sense; I've actually posted the idea a few times (including as an Ask HN) and I was getting fatigued. I absolutely have no interest in making money out of this - just potentially saving lives.

Reposted:

Could a voluntary user-tracking app help reduce the R0 level of the COVID-19 virus?

One of the main challenges with this virus is that carriers of the virus become infectious well before they show symptoms. Consequently, they pass on the infection before they can be isolated.

Apps such as Google Maps already track users' movements to a high level of precision. A similar app could be created that tracked users' movements and notified people they had interacted with if they got infected.

It would work like this:

- Users' movements are tracked
- Upon developing a fever (etc.) the user notifies the app
- The app checks their movements during the estimated period they could have been infectious
- Every other user who was in their presence for X minutes gets notified and requested to isolate themselves
- Recursively check those users' movements to see if they may have passed on the virus

Disadvantages I can think of off the top of my head:

- Requires simultaneous voluntary use by a large proportion of a regional population
- Possibility of false positives by bad actors (would an occasional false positive be so bad)?

I've had this idea checked with a leading epidemiologist, and he was enthusiastic.

I see this same or similar idea has been written up as a paper (which I've just submitted as a separate story): https://www.medrxiv.org/content/10.1101/2020.03.08.20032946v...
And that there isn't 1700 people working on it.
The problem with their thinking is that isolation shouldn't mean you can't go outdoors. The virus is very unlikely to spread outdoors except with very close personal contact. What it does mean is that food should be delivered wherever possible and people should not use public transport. So their thesis that people will get tired of it is built on a faulty assumption.
Kind of expected if you consider https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5684962/

Which is a good plan and similar to what Denmark is doing, ie. stay at home as much as possible, everyone who can work from home does so, closing the borders for all non-essential traffic, and so on. There is a whole system being set up for compensation to concert venues and other businesses who are severely hit by the lockdown and blanket ban on gatherings of more than 100 people.

Open air walks are ok, as long as you keep a reasonable distance to other people. Only go shopping if it's absolutely necessary.

And yet some people are still going to crowded bars, like nothing's going on. It's amazing how stubborn some people are.
Ok I'm probably showing my age here then :) Back in the 1980 and 1990s, the roff suite, and most definitely egrep and classic Thompson DFA construction and DFA->NFA conversion was definitely Unix folklore/taught in Uni. Manpages are still rendered using roff/groff today, so probably many of us are using it regularly. Whereas GNU's texinfo has matured less well I'd say, or wasn't even very useful in practice to begin with due to lack of content.

I'm also using TeX/LaTex, but it's still a programming language whereas roff/eqn etc are non-Turing DSLs and renderers for particular narrow purposes. I get your point, but saying these are "antiquated" is like saying HTML is obsoleted by JavaScript.
Vit D deficiency is omnipresent in today's society. Literally almost everyone I know has it. Supplementing Vit D drastically changed my mood. Too bad public healthcare in Europe, especially the NHS in the UK, doesnt recognize Vit D deficiency as a problem.
While one supplement is in trend, as now with vitamin D, when you search and try to make a decision if you should supplement it, you always end up deciding it is beneficial, or at least doesn't hurt to. But as the trend fades, you may find that it is not that important or even harmful to overdose in specific situations.

So I am skeptical of supplements as a rule. Of course there are a couple of odds, like iodine, which is so beneficial to supplement in general community, that it is added to table salt as default, you only skip if you have specific conditions like thyroid problems.

I wish there were more research or comments on possible harms and disadvantages of excessive use of vitamin D, than I think I could more easily decide to use.
Exactly my thinking.

<disclaimer>I work in a company that deals exclusively with OR. This means that we might be overly specialized for this product.</disclaimer>

I see OR-Tools as an educational product. The tool is easy to start tinkering with and it has superb documentation - even for people not specialized in combinatorial optimization.
I fear that the second this hits major mainstream media, all vitamin D capsules still left in stores will immediately be hoarded by the same people who hoard toilet paper...
I'm not either completely sure about what "OR-Tools" really is, I've considered it an API and packaging to different solvers.

I've used the LP solver [0] for real problems (not on a massive scale), but it worked very nice. Basically a scheduling problem where we very quickly could give the user a pretty decent solution as a starting point that they then could customise. Dramatically shortened the time for the user for that process, compared to the previous random/heuristic "solution" we give.

> Evolution of the local patch is predictable from the patch alone.

Only if you take the experimenter and his decision as part of the local patch, and take the decision to be determined by the same state which also determines the experiment's outcome, which is essentially what superdeterminism is, no?
Most people aren't susceptible to dying from this. They are likely to spread it. Those who are susceptible to dying from this number in the millions. You can worry about your civil liberties and freedom after you worry about infecting someone who might die because you decided that the personal risk to you wasn't worth a few weeks of inconvenience.
Health Secretary Matt Hancock reiterated this morning in his BBC interview that this is not the government's main aim.

It is is a fun buzzword that officials have mentioned and some people have since obsessed about. Which is unfortunate as it really distracts from the real issues so it would be great if we could move on.
I see their documentation also covers routing vehicles across multiple deliveries, with time windows.

Can someone who's tested this stuff out advise on how many deliveries it can handle at a time? The examples only list trivial problems, but that might just be to keep the examples short.

> Thompson DFA construction and DFA->NFA conversion

My (very recent) university education was unfortunately quite light on UNIX folklore, but this was converted in our formal automata course as we traversed the Chomsky hierarchy.
Lost liberty is never temporary, once lost it is lost forever.

Government never roll back control they have ceased. Look at the after effects of 9/11, those provisions where to be "temporary" yet have been renewed endlessly and will always be renewed
It's typically used in reference to a well-known criticism or controversy. If you're the first one to flag the problem, then you would be more precise.
So where does all this dirty water go?
I know from marketing that people should be considered different people in person at home, in person at work, in person at their client's, on the phone, on the web cam 1 on 1, on the cam with multiple people, in text messages. Further modification happens depending on who participate in the conversation.

The funniest example I know is a guy who will first call people then when they say NO in no uncertain terms and hang up on him he drives there and asks exactly the same thing. He frequently describes how both him and the prospect pretend the rude phone call never happened.

He one time needed 100 plants for a stage of a theater performance. On the phone the grower refused to rent them to him, he didn't want to name a price, just NO. In person he immediately agreed to do it for free.
From the first sentence in the abstract:

"however, findings are inconsistent"
Absolutely not, there is still strong advice in terms of regular handwashing etc. Rather the government is saying that you have to time strong lock down procedures correctly. They are saying that outdoor gatherings such as you get at football matches don;t present a high risk (as long as you are washing your hands) compared to the risk of catching the disease from family members in doors.

Moreover they argue that demanding a long-term lock (14 weeks for schools, according to their modelling) is problematic if you go too early - they want to time it to be just before the peak. Basically is playing chicken with an unrushing truck, but a game of chicken with a purpose behind it.

The Chief Medical Officer Chris Whittey is an epidemiologist and I've only heard good things about him. I'm willing to take his advice. They government says it will be publishing the models.
There's a distribution of who gets it when. The bans will be for those last 20% who just refuse to care about anybody else.
Really? I think it's the opposite. It's golden era for celebrities. You have fb, igram, yt and other platforms. You no longer need to be invited to TV or star in a movie. You can trivially publish a blog. Charisma never had as many opportunities as today. Trump, Boris Johnson - many people know they're compulsive liars and still don't care. Respect for academics is probably at its lowest. Science fiction was transformed from a popular science gateway drug to a source of colorful explosions and action movies.
Thanks, this was very clearly written, though I'm already familiar with it. If I got it right, you're saying that the levels of determinism refer to the difference between physical determinism and metaphysical ideas (of which the idea that a conscious being's will influences both the past and the future is an example)?

> But this has nothing to do with the determinism of physical models.

It seems rather confusing to state it has nothing to do with determinism of physical models. More accurately, it does have to do with determinism of physical models if you assume a physicalist perspective, but it might not, though then you have to resort to much more involved and comprehensive models of what consciousness and will are (like changing both the future and past).
Is there a way to force foldit@home to work specifically on coronavirus related jobs?

I installed it few days ago but got so far random assortment of other tasks and nothing about coronavirus so far.
To be fair, if all the "take it seriously people" stay at home as much as possible, you'll be far less likely to encounter them and 90% of the people you'll encounter in public are the people who don't change their behaviour.
Now, more than ever. Talk to the people around you
Why? There is a fusion between the off-line world and the on-line world in some products most of us use, and some of them are good the first time just like Uber.

A lot of things on the internet are broken. Social media is one of them, not only because of the business model they choose but because big tech companies won’t tell us everything.

So we saw this new ecosystem. So necessary at some points, even though unexplored.

From the idea and the decision to make it: one day. To the design: two days. To the whole structure and functionality: three more days. To the AppStore: less than 30 days.

Now it was supposed to be four weeks of testing that way we can start spreading the word. 1st weekend a bar, did an update, 2nd, and 3rd weekend two parties. People loved it, people used it, It was pretty cool cause it worked.

So the noise began. Flights and really really crazy things made us spend more time than we want, and the deadline, that was only 2 months away from the most important project in our lives, it was gonna start to become more.

Then, the Coronavirus came. So this is proximity based total privacy and social platform. People are gonna be alone, in their buildings and homes so we think this could be useful. Nobody knows how or when this will end but it could help someone while they are isolated talking people near them.

Besides the potential help, it will always be a totally free platform and we will be developing new features by request if requested. That way we can focus on what we want and leave this a hobby and as an open platform in case it could be helpful for someone.

This is the code to get access: HUNT2020 It will last 24hs.

After that, each user will have 10 unique codes so we can control the growth and not spend too much money.

If you wanna try it, do it with people around so you can feel the magic and feel a unique experience between the online world and the offline world.

There are things that technology can't replace

Like talking to a room where people are actually present and to 20 people each from their laptop, with the mic muted and the video turned off

It's much harder to 'read the room' and much is lost

And I certainly love working from home and don't fancy socializing much when at work

But technology made a lot of work-related things harder or worse
I'm highly sceptical of it being anything but a placebo for most people. I live in the UK so I'm a good candidate for deficiency but I don't actually feel anything is wrong with me. Everyone thinks they are tired all the time and their sex drive isn't as high as it could be. If I supplement vitamin D the only thing it does is give me constipation. I'm sure there are some people with actual deficiency, but if you're white and go outside sometimes you're probably fine.

> There are almost no drawback to the health system by introducing strict measures sooner rather than later

Yes there are, as set out in the chief medical officer and chief scientific offer's press conference.

> The overwhelming consideration is the blow to the economy. The government should at least have the balls to admit it and not hide behind 'science'.

So, to be clear do you think the Chief Medical Officer and Chief Scientific advisor were simply lying about the science?

Happy user here! I've used it for a couple of projects.

Here's an open source solver for a fun presumably-NP casual video game:

As with other solvers, it can be a little difficult to debug, so I recommend starting small and adding constraints and known test examples.
All previous deterministic password managers could also be used with a counter: instead of inputting site "hackernews" you would input site "hackernews2" etc...

It might not be super long-term but it could be. It seems reasonable that immunity would last long enough until a vaccine was produced.

There's no guarantees. You have to balance the risks up, and not taking this approach is risky in itself.
Right, I have a lot of stances that a lot of people don't hold & I manage to "live and let live".

Ultimately I think we're all responsible for our own morals & I generally don't get worked up about people having different ideas (notwithstanding such that deny my right to exist, such as antisemites).

Absolutely, not only respiratory but all the illnesses. It affects your immune system. But with cavaets:

- It won't make any effect for around month once you start taking it

- it only has effect if you have serious deficiency.

I used to be sick really easily for years, always tired. Finally got doctor to make blood tests and if normal level 100, min is 60, then my vitamin D levels were 12. Ofcourse my body immune system struggled. After started with suppliments got more energy, got less often sick. Felt like a normal person.

There is also other extreme, taking too many will have negative effect. I've experienced them myself.

I do live in a northern climate (imagine Finland) with long dark winters and only sun time is spend in the office.
My attempts at code generation with Go
Packet captures are helpful even if you’re not personally involved in the networking layer, but still talk to the internet and would like to keep logs of it. My university organizes capture-the-flag competitions and everything that goes through the game network is captured, both by us and by many of the teams. The captures let us monitor the state of the game, quickly detect and respond to denial of service attacks, and serve as a sanity check of the event in case some critical infrastructure goes down and we lose game data. Good teams log all their traffic so they can reverse-engineer and replay exploits that people shoot at them, of course ;)
I agree with everything, including not normally being a fan of the government. But this is the most scientific and realistic approach. it's all been done quite sensibly, except maybe communication could have been better.

There have been some bold, counter-intuitive and unpopular decisions, which I really hope pay off. My prediction is that at the end of all this the UK will end up with significantly fewer deaths proportionally than most or even all other countries.
While we're at it, we might as well let LastPass have all the words that end in "Pass".
In general, these types of utilities don't treat the state (counters, password rules, etc.) as a secret, so I wouldn't count on the hash type being secret either. The security of this type of scheme depends almost entirely on not being able to reverse a presumably known key derivation function such as scrypt.
