sounds interesting, i'll have a look at the code when i have time. i've mostly done compiler stuff like this with the "one function with a huge switch on the expression type" approach, curious to see what the more OOP-ish way looks like.

btw: wow, that cheatsheet is exactly what i had in mind on my first comment, that's the kind of stuff i'd like in a readme! maybe a few excerpts with a link to the whole thing.

some more remarks if you're interested:

---

in that cheatsheet it'd be cool to also show the generated code for each example, maybe in a collapsible box or sth – in that context the actual semantics of a convtools expression are useful to know.

---

have you thought about some magic syntactic sugar? the current approach is kind of visually heavy, since you're basically writing an AST by hand. with some __dunder__ hacking you could easily (?) add a "magic" api like

from convtools.magic import magic as m

c.item('key') ->
m['key']

c.call_method('foo', ...) ->
m.meth.foo(...)

c.call_function('bar', ...) ->
m.func.bar(...)

or something similar. it might be a bit too magical for some tastes, but if you're constructing a python expression, it kind of makes sense to use python syntax for that
What if we already have a partial COVID-19 vaccine?
This was posted here a while back: https://neherlab.org/covid19/

They have number of deaths displayed, so if you try to match the observed rate and keep total deaths below 200k... well, it's doable, but with pretty strong assumptions.
I don't see how your contention really fits - physics Olympiad types are by definition not general.

For what it's worth, when I was in that position I found some of the Landau and Lifshitz stuff at least as insightful. I'm all for Feynman as a supplement, by the way.
Something not commonly talked about is knowing how to respect the IC's that a lead/manager will manage. All the bad leads/managers i've had, had always been people who would jump to please their bosses and take on horrible deadlines or scopes that put huge amounts of stress on the people they managed. This lack of awareness to a balance in productivity for personal gain is very apparent to your employees and they will lash out by slacking, leaving the company, or sabotaging the project just to get one over the lead/manager. The best managers i've had will push back against their bosses and tell them what's realistically possible to do because they're aware of their employees stengths and weaknesses, knows that en employee just had a personal tragedy and won't be able to be working at 100% for the forceeable future, etc etc. lastly i've seen companies try measuring things like lines of code committed per day, and that never ever works out the way upper management thinks.
But they aren't going to achieve that on low prices alone. That's just reality. Coronavirus has placed Russia squarely in the driver's seat here. Saudi production surplus or no surplus is meaningless as Covid is depressing prices in any case. (And will continue to do so for the foreseeable future.)

So what is the Saudi endgame? Keep prices low for an additional year after the global economy recovers from covid-19? (Which covid-19 recovery, in and of itself, could take a year?)

It just doesn't make sense unless they have some other weapon in their arsenal here. Which they might? I just don't know what it is. (But if anyone does they could make a billion right now trading.)

Totally true. Obviously nobody knows right now if that will happen or not, but that question was posed on a recent episode of This Week in Virology (great podcast, btw) and they seemed to be saying that the mutated seasonal variant is a fairly unique characteristic of the flu virus, and it would not be _likely_ to happen with COVID-19.

We read horror stories in the media because they make good stories, but in fact, people fuck up all the time in business and then it's just reversed because in most cases, nobody is irrationally out for their pound of flesh. People fat finger multimillion dollar trades on Wall Street and while I don't know that it's guaranteed to work out, I definitely have read about instances of that being reversed.

If cryptocurrency and smart contracts make sense to you, you might not be aware that forgiveness for human error really does happen in normal business.

Exactly. Fatality rates are mostly just a function of a country's testing (how much testing they're doing, and how biased the sample is).

If you're only testing a small # of people with severe symptoms, obviously the fatality rate will look really high. If you're testing a much wider section of the population, and testing people who aren't severely sick, the number will look lower.

Some examples:
- Iceland randomly tested people in the general population (no symptoms), they found ~1% of people tested positive, and half of those had no symptoms (and so probably wouldn't be tested). [1]
- Italy tested an entire village (the village had a cluster of cases), 3% tested positive, of which half had no symptoms.
- One professor used the Diamond Princess cruise ship as a baseline, and estimated anywhere from 0.025%-0.625% [2]
- China had a fatality rate of 17% initially, which went down to 0.7% if you only consider symptom onset _after_ Feb 1st. [3]

Of course, there are a lot of other factors, and it's possible that the rates end up in fact being really high, but there's an argument that we just don't know how many people are infected and fatality ends up being a lot lower then just dividing # of deaths by # of confirmed cases would have you believe.

Just to be clear: even the lower case scenarios are really serious and worrying, and I'm definitely not in the "this is just another flu" camp. But there's a huge range of uncertainty here.

You are assuming dead or perfect health is the only outcome. Besides, since it takes on average about 2 weeks to die of this disease after being admitted to hospital, you should compare today's dead rate with the number of admitted cases 2 weeks ago.
Sam seems preoccupied with a weaponized virus rather than a natural mutation.

Gates had a 2015 TED talk about “the next epidemic”

Hopefully we will be more prepared for the next one. Covid-19’s mortality is much lower than 50%, so in some sense this is a warm up for the big one that Sam fears.

It might be as simple as there as tens of thousands of 18 year olds ready to fill existing Bachelor’s programs straight out of High School. The financing for that is low hanging fruit, they can use their federal aid or loans to pay for several semesters (whether they pass or fail). This stream of cash is easy money, new adults and their parents are expected to spend their time and money on this from a cultural standpoint. There’s nothing to switch up in this business model.

Now take a Master’s program. Most people are done with college and are working full time. If you seriously want their business, you better offer them every flexibility in the world. It’s a whole different game.

One group is literally groomed to hand you money, often not even their own. The latter is a group that is no longer part of that setup and will make an independent decision based on a variety of factors.
Look how radiologists work nowadays. They don't see their patients face to face. Everything except the decision making has been handed to someone else so they can be most efficient. That's the model a huge COVID19 ICU could work like.

True, but that seem to be a reasonable assumption according to at least some virologists looking at it.

There are so many unknowns right now that any modeling is going to have issues, best you can do is state your assumptions clearly, and explore the ones that seem most likely in some depth. Otherwise you just end up with an ensemble of models that could result if nearly anything.
Now we are comparing who is worse, I claim both are bad actors and currently would pick a different one than you. We can each cherry pick specific cases/aspects and ignore/marginalize those we don't.

OK, so just one random point, China is bullying around. What about citizens of: Vietnam, Iraq, Afghanistan, Syria, Yemen, Iran, etc. China is bullying Taiwan. Compared to US killing millions of civilians and ruined future for hundreds of millions by its actions. Many wars started without any real cause. How can you even compare this...

But I guess you completely ignore these matters. You ignore NSA spying on every citizen of this planet as long as they do anything, ever online. As an European, you don't really mind being treated as sub-human being by US government on US soil (way less human and civil rights compared to US citizen, if you are suspect of terrorism than this is valid globally). I guess you don't care about Guantanamo. I guess as an European, you don't mind that US is exempt from International tribunal for war crimes in Haague, so companies like Blackwater can basically kill whoever they want.

I have no doubt China might do the same under some theoretical circumstances. But saying who is better and worse is very relative in this topic.

I've come across a fair share of zero-alloc implementations of various things, like u/poitrus' zerolog [0] and u/jorangreef's cuckoo-hashtable [1], for instance.

Given that JavaScript runs on restrictive clients, it must have libraries in spades for this kind of a thing, but I couldn't find many. I'm really interested in techniques that are generally employed in languages like Java, Golang, Rust, C/++ that are worth translating over to JavaScript, especially now that TypedArrays are a reality. I'm pretty sure there's more to zero-alloc than just Buffers, Object pools, and Recyclables, but I can't seem to find good resources to get started with this.

As you point out, the body can tolerate significant variation in absolute pressure, corresponding to the temperature, composition, and density of the gas you breathe.

The pressure that must be narrowly controlled in a ventilator application is the relative pressure: the difference between the absolute pressure outside the lung (in the room) and the absolute pressure inside the lung. This relative pressure is what does all the work --- mechanically opening airways and alveoli --- and could cause all the injury.

Are there any major cloud hosting/computing providers which do provide a hard spend limit?

We've heard the horror stories from the Google data egress pricing "surprises" (like that GPT adventure game guy incurred a few month ago https://news.ycombinator.com/item?id=21739879).

We've heard the AWS and Azure horror stories.

It seems crazy that the only hope of correcting a mistaken overspend is a helpful support desk. The first one is free, right?

At least AWS does have such a support desk, Azure may have and with GCP you are better off just shuting down the company.

How about lesser providers such as Digital Ocean.

Let's say your code mistakenly provisions 1000 droplets instead of 100. Is this a scenario you can prevent at an admin level?
> We worry about terrorist attacks and necrotizing fasciitis, but not much about heart disease or car crashes. But in 2011, 17 US citizens worldwide died as a result of terrorism and approximately 150 from necrotizing fasciitis. There were nearly 600,000 deaths resulting from heart disease and over 32,000 from car crashes.

> Based on current data, you are about 35,000 times more likely to die from heart disease than from a terrorist attack. So everyone smart says that we worry about terrorism way too much, and so far, they’ve been right.

Yes, thanks to our natural preference of exceptions, rarities, and oddities which the media fuels us with.

However this ignores any mitigation (and their costs) being done on these dangers. A proper risk analysis includes these.

> But another possibility is that we engineer the perfect happiness drug, with no bad side effects, and no one wants to do anything but lay in bed and take this drug all day, sapping all ambition from the human race. There are a lot of other possibilities too, and it’s very hard to think of them because we don’t have much experience with what's about to happen.

I'm not at all frightened by that because all drugs in past failed on that one. There is no up without a down.

On top of that, human beings want to be useful, they want to give their life purpose. Even if that involves pain. Laying all day in bed (or in quarantine) feels awful.
It's the same argument as - if a company can run a multi-billion dollar operation, can they not afford their own datacenters? They can, but AWS just makes things easier and often cheaper.

The core competency of a business you describe is building, launching and maintaining satellites. On-ground network infrastructure, computing hardware, data processing, machine learning etc. is something AWS is a lot more familiar with.
Atm it only takes a straight line through a couple of points to predict things for most countries, so I'd say yes.

The interesting question is whether they could help to implement useful political interventions based on which parameters matter.
The answer seems to be yes in many cases.
> For this particular crisis, yes.

Really not even for this particular crisis. We can build more of something on a short timescale, it just costs more then. You have to build facilities you know are only going to run for six months and then be decommissioned, so you have to amortize their construction cost over half a year instead of 30 years. You have to build them on the double, which means paying a lot of overtime and buying land and raw materials without taking a lot of time to negotiate on price or worry about efficiency. But we could do it.

And then the ventilators would cost ten times more than they ordinarily do and idiots would accuse anybody trying to do this of price gouging. But it could be done. (Unless the idiots pass a law against charging more than the regular price during an emergency.)
But deaths is influenced by health care capacity.

What about looking at number of people in need of emergency care?

In France, we have a stricter lockdown (e.g. we're not allowed to wander to more than 1km from our home - which is BS in my opinion). I'm wondering if the bulk of the measures is enough: closing school, restaurants, preventing gathering and so on... If this is the case, I don't expect different outcome in Sweden compared to other western countries.

Hey everyone,

I recently created fdir mostly out of curiosity about how fast a program written in Node.js could be. It so happened that I (accidentally) created the fastest directory crawler in the NodeJS environment. fdir can easily crawl around 1 million files in under 1 second. 1 million files distributed in about 100k directories. (your mileage may vary depending on hardware).

It's also < 1kb in size (gzipped). Supports all node versions (> 6).

Feel free to give it a run and ask me any questions (if any) :D

If it was easy, someone would have figured it by now, after hundreds of years of shareholder capitalism. At the end of the day, real world business is risky, and someone must be taking that risk. If lending companies are asked to both front the money and take the risk, there will be no lending companies and no financing.

dunno, I kinda think that the right actions at the right time can [could have] make a huge difference. I think that if the rest of the country shut down the way CA and NY did... we'd have a real chance at this thing being a month-long crisis. (Of course, the real test here is how bad it ends up getting in CA; California shut down earlier in it's spread than NY. If I'm right, that means the peak won't be as bad here... but that is yet to be seen.)

I also think the cuts to the county health department are... normally mitigated by an ample federal response.
I'm not saying "zero training". I'm suggesting the minimum training necessary to run a ventilator. That way doctors or nurses could simply hand off care to ventilator-operators who could contact the doctor or nurses if things got out of control. This wouldn't be as high quality care as people would usually get, but hopefully it would be better than nothing.

Regarding whether doctors would want undertrained help - that's immaterial. If current healthcare workers have the capacity to handle the pending wave of sick people, then that's great and we shouldn't get in their way. If they have another, better solution, then let's do that. If the alternative to having minimally trained people operate ventilators is letting people die without any intervention - I'd want to see some explanation or evidence as to why letting people die is better.
