Otoh, the epidemic in the US is likely growing exponentially, and that encourages the current CFR to underestimate the actual CFR as new cases haven't had time to die.

In terms of estimating the IFR, it's hard; estimates are about 0.7, much higher than flu.

Your link says 'mean R0 1.3: range 0.9 to 2.1'.

Compared to the mean R0 of flu, this disease spreads substantially more and is more lethal, hence is a good counterpoint to the flawed argument of the post that I was replying to.
I think it's more complicated than that and the people decrying "wasted" negative tests are [redacted] idiots.

If you're at home with what appears to be a relatively mild case of COVID, testing you doesn't tell us much right now[0]. Isolate yourself, even from your cohabitants, and scrub everything like the dickens when you feel better. You should be doing this anyway, even if it's "just" the flu.

Testing people that were around you, however, is critical for preventing the virus from spreading. This is especially true for people are asymptomatic or presymptomatic but nevertheless shed the virus.

[0] This might change in the future as we learn more about if and how long the immunity lasts; perhaps you could go back to work. Hopefully sereological testing will fill that gap soon.
The fatality rate and the total number of cases reported by Italy don't really mean much if anything at this point. Because their health system is overwhelmed they are mainly only testing people who already have severe symptoms which inflates the fatality rate as most mild cases are never identified. While it's reasonable to assume that's it's higher there than in places like South Korea or Germany it's very likely that it's still considerable less than anything close to 9%.
Well some of those are of course found among primarily old people, but as I understand it there are plenty of young people who are in critical condition in Italy as well.
> Il numero medio di patologie osservate in questa popolazione è di 2.7 (mediana 2, Deviazione Standard 1.6)

It seems the above poses another question; is diabetes just confounding other underlying condition(s)?

Further, if most of the patients suffered from type 2 diabetes, it would likely correlate with older age in which case higher fatality rates are to be expected.

I was unable to find this info publicly available, but diabetes being one of the "2+ underlying conditions" seems probable.
Funny Resident Evil 3 Reaction
I live in the UK and panic-buying is not anecdotal. Just today, the government pleaded with shoppers to show responsibility and think of emergency personnel, such as NHS staff, who can't go shopping early in the day and are left with nothing in the evening:

https://www.theguardian.com/world/2020/mar/21/coronavirus-uk...

Also, supermarkets are imposing limits on goods to stop hoarding:

https://www.theguardian.com/business/2020/mar/18/asda-puts-r...

And the governemtn is relaxing trade rules so that supermarkets can work together to face the unfolding crisis:

https://www.theguardian.com/business/2020/mar/19/food-retail...

So in the UK at least, panic-buying is a thing.

Edit: and, btw, it's a thing that's hitting me hard because I refuse to go mad along with everyone else and hoard. Unfortunately for me, the government and supermarkets have plans in place to ensure vunlerable people have access to goods, but there's no such provisions for people who have just not gone mad yet. So I fear I might want for basic stuff as time goes by.

People are such shits when they're running scared.
Ask HN: How can a intermediate-beginner learn Unix/Linux and programming?
For a long time, I’ve been in an awkward position with my knowledge of computers. I know basic JavaScript (syntax and booleans and nothing more). I’ve learned the bare basics of Linux from setting up a Pi-hole. I understand the concept of secure hashes. I even know some regex.

The problem is, I know so little that I can’t actually do anything with this knowledge. I suppose I’m looking for a tutorial that will teach me to be comfortable with the command line and a Unix environment, while also teaching me to code a language. Where should I start?
Corona virus (Covid 19) Bash tracking CLI tool – New version pushed
Yes you should. I learned development on my own and, yes, I landed lots of jobs. However there are barriers:

- without a cs degree several avenues of kernel development

- ditto distributed systems

- anything with a strong quantitative basis

- formal tools/tooling

- specialty data structures and algorithms

Will be beyond reach. You simply won't be able to cope.
I went on to get a mathematics degree and that saved my bacon when older and had needs beyond a paying gig (read family and house).

Do not under estimate the need to write clearly. On above topics bubbles and arrows don't cut it. You need to write papers, and/or formally model if you want to communicate and prove non trivial results.

Learning languages is one thing. Having a deep understanding of the libraries that come with the language (simple example: STL) is also quite important.

Finally given a choice between a guy with a degree and a guy without ... The guy with shows he/she can finish something of difficulty in four years. This is not to say MIT grads are always better. But a degree is better than none.
Extraordinary claims require extraordinary evidence or in your case, any. It's on you to prove it not vise versa.
It's implemented as a buffer and some associated state. A process that writes to the buffer can do so until it is full, at which point the thread is suspended (blocked on the write() call) until it is not full. The read() side is similar --- reads return successive data in the buffer unless it is empty, at which point the read() call will block.
Yeah, I haven’t played it myself but it’s unquestionably a significant entry in the genre.
I mean newly started projects. Of course there's a ton of existing code to maintain, but — at least in my team — Rust is the default for new services.

How would you know they haven’t? If you don’t test a death for the virus, the death doesn’t show up in virus death counts. And if you aren’t in a hospitals, the deaths wouldn’t show yet.

At some point it would become too big to ignore. But is Japan there yet? This is definitely a space to watch over the next 2-3 weeks.
the number of cases presenting themselves for testing follows the exponential curve. people are displaying symptoms in numbers following an exponential curve.

when the number of symtomatics become very large and saturate the testing process, the reporting will no longer follow the real curve of cases over time, only the number of test that can be performed over time.

You don't need a "goddamn" degree to learn any single thing you can learn on a degree, and this applies to pretty much any degree you can think of, the books are available, as is online research.

The point is during a degree you are lead to some topics and guided through them.

Better performance in the same way a laptop performs better than a microwave, or a mechanical device.

People were fine with mechanical speedometers, but manufactures moved to microprocessors because of cost/features, and seem to be moving towards mainstream computers for the same reason.

People don't need these features. A mechanical speedo would suffice, but they seem to want them.

Along the same lines, people would be fine if the only car available were some kind of utilitarian hatch or station wagon, but people want cars with different attributes and manufactures offer and optimize for those attributes.

Having in car entertainment can help to make longer refueling stops more pleasant, which arguably helps with adoption. But it's not a requirement. Tesla could have skipped it and lived with however many different sales, in the same way including it led to different sales.

It could be a multitude of reasons. Try not to think of it as a robotic pipeline even though it appears that way. The interviewer could have been sincere but there are a lot of hard decisions / politics / etc. behind the scenes:

• The hiring manager for the team(s) could have been mandated to put in a hiring freeze

• You may have provided an optimal solution but the interviewer couldn’t see himself working with you everyday — at the end of the day this is what it’s all about you want to hire someone you are able to work well with everyday. Not likely the case here though something to consider

• Budget could have gone down

• Headcount reductions

• They night have found a better fit candidate

• Things might be chaotic as even if you do hired your can’t come into HQ until the virus passes

• [Insert any other reason here]

I remember getting that a few years ago with some bad infection.

It is awful - nothing has any "taste" (using quotes as we often confuse taste and smell. I could taste sweet/salty etc but this is a very small part of the overall sensory experience compared to smells)

I would eat blue cheese and raw garlic to try to get some kind of taste, because everything was insipid. So I would barely eat anything, unless I felt hungry. Then, I would mostly eat pasta, because at least the texture was nice. Only texture mattered.

Spices helped. Lots of them, put directly over the pasta. Meat felt like old bubblegum, something hard to chew and without any flavoring.

In my case, it took more than a month to heal. I believe my sense of smell was permanently altered because since then, I don't like anymore many things with a faint taste that I loved before.

Raw mozarella for example still tastes like chewing boiled spaghettis. Only the texture is different. I loved the aftertaste of mozarella before, but I can't find any taste to it anymore.

> What about this work made you happy? What was the reward?

It's like a really complicated puzzle. I have this game that's not working, and I have this 2 GiB trace log of millions of lines of CPU instructions and registers. I have to sort through it to understand where things went wrong. Sometimes it's obvious and takes five minutes, sometimes it takes two weeks and is mind-bending (like a loop reading from a non-existent I/O register that only breaks because eventually a DMA transfer occurs in between cycle instructions that fetches the correct value onto the data bus, which stays persistent through to the next cycle that compares the value read to finally break said loop.)

I really enjoyed over-architecting the code, and I would build these massively elaborate (read: slow) designs to handle the most ridiculous edge cases (like stacking Game Genie cartridges one after another recursively. It's an incredibly inefficient way of getting more cheat code slots, but you can do it on real hardware, and so I wanted to preserve that experience.)

I'm under no delusions of granduer, these were "just video games", but I definitely had the sense that if I didn't do this, no one else would. The SNES was a large part of my childhood, and I had the skill and time to do this, so I went for it.

Java is a bit different though. Whatever we think of 'enterprisey', it does mean that a lot of systems were built with it with the expectation it would be around a long time.

As far as 'bets' go, it's also a bet on oneself. The skills of an 'average' developer between two languages can have notable differences in concepts and requirements. i.e. I'd be a bit curious about an 'Average' C/C++ Developer who couldn't write a linked list (or at least groks them), versus an 'Average' C# or Java developer who may never have to write one in their career.

I'll say that unless you intend to be a hardcore Systems developer or Finance Sector, Javascript is never a bad thing to at least learn enough of to at least pass equality questions on interviews.

The nice thing about learning other languages however is that it may help expose you to patterns you don't normally see in your main language, or may expose you to things that make it easier to understand certain concepts (i.e. doing Javascript sites with KnockoutJS helped me learn better MVVM practices, as well as concepts like observables which I could then use back in C#)

I’ve been diving deeper into Crystal (which I think is amazing and elegant and really fun to code in) and learning Svelte, which is also awesome and powerful.

I released a super early alpha preview do-not-use-this-in-production version of a mini-framework to builds web apps with Svelte as a drop-in for the view layer and Crystal on the back end:

https://github.com/noahlh/celestite

It’s nothing fancy - but it works with existing Crystal web frameworks and, I hope, could be pretty cool eventually.

Would love feedback and extra pairs of eyes on it!
It’s not that bad. Look at the bottom of this page: https://www.odysseymanufacturing.com/ultrachlor-bleach

A few things here are worth noting. Highly pure bleach is more stable. And chlorate is undesirable and mildly toxic. You don’t want too much in your drinking water.

From experience, one should only buy bleach from stores with decent turnover. Bleach from the corner store may well be dead.

It's probably temporary as it is basically being listed as a symptom.

The significance here is that it may be a symptom of infection in those who are otherwise asymptomatic. Thus it potentially serves as a quick and dirty test for who should err on the side of self isolating even if they don't feel sick to try to stop the spread.
This exactly. Medicine is all about the dosage. If we are overreacting than we're not helping people extra - we're actively hurting people.

The U.S. response is absurd.

I’ve been wondering the same thing about Massachusetts where I live.

We have 416 confirmed cases, 58 requiring hospitalization - it’s unclear how many of those require the ICU. I know of several people who are suspected of having it but have been told to just self quarantine but haven’t been tested, so obviously the infected numbers are much higher.

Still we only had our first death yesterday. He was an 87 year old already in poor health. By this point in Italy, things were already much worse.

Is this the beginning of the tsunami, or is it possible that it won’t get as virulent here?
