> Even on Diamond Princess, you have 10/712 infections resulting in death which is worse than flu (for this population)

You still have to compare that to the baseline of the demographic. I.e. once you’re over eighty, you have almost a 1% probability to die within the next month.
>What it could not survive was the cutting of its grain supply, and the end of the administrative apparatus that ensured its regular delivery.

one of the most recent examples - USSR - the low oil prices of the 198x coupled with the peak cold in the 80 years cycle meant that the resulting low agricultural yield couldn't be supplanted by the required massive import of food, so that time the Russian Empire (USSR) cracked. 80 years before that the Russian Empire had revolution of 1905-06, and while that revolution failed it resulted in a lot of deep changes to the country, in particular agrarian reforms (including introducing peasants' private property on agrarian lands) and huge expansion of Russian agriculture into Siberian regions.

So, i think that one can estimate the probability of "How do you know if you’re living through the death of a specific government instance/structure/order." by looking at the basic Maslow layers - food and security. This is for example why China Communist Party is hell bent on delivering growth and prosperity and stomping out hard measure style any threats to stability, be it coronavirus or dissidents.

+1 to both Middlemarch and Bleak House - I generally go for the Russians over the Brits when it comes to 19th century fiction, but those two are the exception. And both Eliot and Dickens certainly influenced Tolstoy, at least according to this list of books he himself compiled: http://www.openculture.com/2014/07/leo-tolstoy-creates-a-lis...
If anyone remembers who wrote it plz say:

First people work hard and barely survive

Second people work hard and have enough

3rd people just work and have enough

4th people barely work and have more than enough

5th Earning things is replaced with entitlements and some have to work hard to make it so.

6th the entitled class grows beyond support then everything caves in.

And everything starts over again.

In short: To find the end, look for the entitlements.

I'm not at all defending the absurd US system.

My point is more that there is no single other well thought out system that works in every other country.

Those 30+ systems are very different from each other. Most of them are also in some kind of crisis, if you ask local public opinion.

I'm arguing against the simplistic "let's just convert to the other system" idea. This isn't like going metric.

Sorry, yes. Thanks for the correction!
I'd sort the input as it arrives, using heap sort.

The thing is, you could just not worry about the stream, as it is TCP/IP based. The core idea is to read a number from the stream, append to the array that makes up the heap, and run heap sort.

The only important thing is to keep the tcp/ip connection alive. If sorting takes too much, tcp will take care of sending the last sent number again.

This might not be super efficient though.

This could also be done in batches (4kb? 8kb?) -- we don't know about network speed or latencies, so we might work on that.

We had an understanding of the virus and the dangers. Not only that we had real examples of it spreading outside of China. We chose to do nothing.
What about a virus that spreads to everyone before it triggered by some secondary catalyst virus?
That's a weak argument, in my opinion. I've commented on this in the past, but there's nothing physically stopping hospitals and other institutions with their own funding from opening of more spots. You can definitely get ACGME accreditation without CMS funding for your program, institutions just need to be willing to find other funding.
I've been a fan of Khan Academy since they were just some Youtube videos.

You can find Khan Academy's past Form 990 online and I've been archiving them.

Sal Khan made:

2008: ? ($0 revenue)

2009: ?

2010: $70,833

2011: $348,879

2012: $348,529

2013: $348,292

2014: $548,116

2015: $800,000

2016: $815,000

2017: $785,000

2018: $824,000

You can see that, just like a startup, the sacrifice in the beginning as a founder is real. Before 2010 his salary from KA was probably 0 or significantly less. $70K in 2010 was less than my new grad salary. The jump in 2011 to $350K is around how much a senior makes in HCOL areas now. There has been basically no adjustment in his earning for 4 years from 2015 to 2018.

From the 990 forms, you can also get a sense of how much other people in the organization are being paid. I think all of them can command higher compensation elsewhere, but choose to work at KA because leveling the playing field for education is such a great mission.

Sal Khan's compensation as a CEO is only ~3.x times of many senior positions in the organization. Not outrageous at all.

In 2008's Form 990, Sal Khan wrote that KA is being used by 10,000 students daily. I don't know how many accounts, but growing from that to 71 million in 2018 is incredible. The impact to the world is undeniable.
I also didn't love Fall Or: Dodge in Hell as a book, but found the concepts within it interesting (especially around the media curation each person has as I'm advising a startup that monitors disinformation campaigns)
Yes, and what does that buy you? Instead of a single deployable unit that owns the database, there are many deployable units, none of which can own the database. That doesn't seem like an improvement.
A more practical version of that same solution would be to use some serverless endpoint to do the sorting (or even just the storing).
Speaker for the Dead (sequel to Ender's Game) was magnificent
No, they did not. The Swedish government stopped testing to conserve resources due to a severe lack of test kits.

I have some criticism of the lack of transparency from the Swedish government, but they did not stop testing to hide anything. The lack of testing resources was very real.

No, we're causing strong selection bias towards something like the common cold.
I'd agree with you for this post, minus the weird re/usability semantics, but that interpretation goes against the previous parts of this series.

If you read Part 1, the argument is largely against even well-architectured versions of re-usability. The author takes issue with all components designed for drop-in future use, believing that each problem requires a tailor-made solution.

The re/usability debate seems weirdly entangled with the coupling debate for no good reason. The author believes re-usability means tight coupling, and "usability" means good APIs with loose coupling (which can be re-used...).
The circuitbreaker everyone would want is probably: "Drop all compute with its ephemeral storage, when the cost of every resource already used and the projected cost of my stable storage (EBS+S3+Glacier+Aurora+Whatnot) is greater than my preset $MONTHLY_MAXIMUM.

That means any data getting lost as a result of that limit is data that they weren't guaranteeing in the first place. You might not be able to actually read your EBS volumes, S3 buckets or Aurora tables without increasing the spending limit or otherwise committing more funds, but it won't go away that second, and you would have enough time to fix it (worst case - wait until next month; you did budget that already).

Alternatively: assign each resource to a pool, and monthly spending limits to each pool. Give your EBS/S3 $1000/month, and your R&D-pet-project-that-may-accidentally-spawn-a-billion-machines $50/month.
But if a test fails does it now mean you're bankrupt?
> It could be that Swedes are following the norms established everywhere else, even if 'lockdown' orders are not that hard.

Well, it could be but it's not that there is any numbers to back up anything yet. I do think that the difference in reality is smaller than the percieved difference in policy. Some headlines would have you believe that we are ignoring the pandemic and everyone just goes to work normally.
That is true, I don't have any evidence to say that x86 isn't faster or equal against Apple's ARM CPUs or vis versa. They're hard to come by since they're both completely different arch.

For JS: https://twitter.com/codinghorror/status/1049082262854094848

It looks like it's not exclusive to Apple's CPU, it's the specific instruction features in ARM 8.3 ISA that makes JS faster.

> Any modern x86 CPU can do accelerated AES just as fast as any ARM with hardware crypto support.

Right but back then, Intel mobile chips weren't that fast. I had MBP with Filevault that took a massive hit and I had to turn it off to get back disk performance. I can't prove that T2 is the reason the encryption doesn't take any hit on T2 Macs, all I can see from my trial of rMBP 16, there was zero performance hit with it on or off.
Wow, all I did was use a phrase from popular culture, and now I feel I'm being speech shamed.
I'm glad to know I'm not alone. I genuinely can't figure out the enthusiasm for TBP.

Elizabeth Warren for President open-sources its 2020 campaign tech
I live in northern Sweden. This is some of my anecdotal sense. My children's school is still, technically, open. However, according to my neighbor who is a teacher there, there are only a small handful of children actually present any given day. On Friday, I think she said there were 2 children present.

Edit: This is not to say that I have any idea about elsewhere. And, again, just one fairly not useful data point. Just an observation.
Not really, the data they communicate that they are basing their decisions on are the number being admitted to ICU per day. Which actually has been decreasing in Sweden and is a hard fact you can't deny. Since everyone really sick will end up there. Not the unknown number, which you might catch a percentage of the general population by testing.

Sweden has now started anti-body tests on general populations to try to get more correct statistics across the whole population.

So yes, testing is amazing and super important in the early phase, i.e. Korea when it was fairly localized and contact tracing worked well enough. When community spread is there in several places all you can do is limit the it according to the models.

Show HN: Recipe Costing application
Hello everyone!

I recently graduated from Udacity's Intro to programming program.

I am excited to share my first made-from-scratch project (i.e with Flask/Bootstrap): a Recipe Costing application using Google Sheets as a database.

Here is the link to the repo https://github.com/skarmen/recipe-costing-app. I have also deployed the app successfully on Heroku (auth access is required).

I have been working part-time on this project for 3 months now, learning as I go. I'm eager to learn more so any feedback would be greatly appreciated!

Please feel free to connect with me with any junior web dev opportunities in Toronto or remote!
We should take up our burdens, since we can only blame ourselves for not preparing. I don’t think the issue was believing in China (as you stated China is known for suppressing information), the issue was hubris. There were plenty of signals that the virus was spreading and still we did not do anything effective while some other countries did. We have our own leaders to blame and it would be more effective to select better leaders than to blame external sources.

Not that I know of. I just keep an eye out for nearby theaters performing it.
I can't stress enough how important this factor is... without widespread randomized testing of the population, we have no idea what the true infection rate is or how widespread the virus really is. Our current stats have a huge selection bias problem.

This is why it is so important that we take social distancing, self hygiene, and shelter-in-place measures really seriously in order to protect those among us who may be more susceptible to severe infection.

The silver lining: the more widespread the virus, and hence the number of asymptomatic cases... lower the actual the severity statistics are.

i.e. we know "number of deaths", "number of hospitalizations", and "number of positive cases". Right now, when we calculate our various severity rates, we are putting "number of positive cases" in the denominator because we don't know the number of actual infections. There is an unknown multiplier (>= 1) relating positive cases to infections. All our severity statistics need to be divided by this unknown multiplier. But right now, since we don't know what it is... the responsible thing to do for reporting and policy decisions is assume it is 1 (worst case). It is not 1... it is greater than 1... we all know that. But how much is a tough question to answer properly without proper statistical sampling of the population.

There are modelling studies and estimates that suggest value ranges for the multiplier, but I don't want to spread potentially false information on a public forum.
Is there a reason MKL isn't shipped by default? I can't believe there is so much 'free' performance available that so many people are missing out on.
Nearly every time the USMC list goes up on HN, the reaction is the same: Why the heck is Ready Player One on the list?

Thanks for diving a bit deeper into the selection.

To add a bit more context, the USMCRL has this in addition to the categorization:

"2044. Like most of humanity, Wade Watts escapes this depressing reality by spending his waking hours jacked into the OASIS, a sprawling virtual utopia where you can be anything you want to be, where you can live and play and fall in love on any of ten thousand planets..."

As the selection is in the 'Primary Level - Enlisted' alongside Ender's Game and Rifleman Dodd, I think it is there to showcase initiative and intelligence for young enlisted marines.

Still, I'll admit, it is a strange choice.
In my late teenage years, I was fond of Hesse's novels. Demian was interesting enough to get me started. Narziss und Goldmund was by far my favorite. Siddhartha was also a good read, but at this point it was getting repetitive with its other works, and I didn't share the author's fascination for Indian religion and philosophy. Der Steppenwolf was a disappointment.

A few years later, a friend lent me Das Glasperlenspiel (The Glass Bead Game). I was deeply surprised, because it was so different from his previous works. It's a dystopia, but the focus is elsewhere. The book is much less romantic than usual, more subtle and intriguing. Twenty years later , I remember it fondly, and I can't think of any similar book. If you like Hesse, you really should try his last novel.
Also keep in mind China is a massive country with over 2 billion people. Just by having a denser population they are more likely to catch a mutation.
I finally read Frank Herbert's "Dune" this year and I'm so happy about the decision to finish the book. In the book are several references to what is known as the "Litany Against Fear". You may have come across references to it in pop culture, where the beginning is often cited. For instance, Elon Musk references it often.

The Litany in its entirety:

> "I must not fear. Fear is the mind-killer. Fear is the little-death that brings total obliteration. I will face my fear. I will permit it to pass over me and through me. And when it has gone past I will turn the inner eye to see its path. Where the fear has gone there will be nothing. Only I will remain."

Learning how to manage fear is something I think we can all benefit by.
Even in C and C++ you still need to optimize to get rid of allocations.

Maybe the allocations are more obvious, because you usually have to write them out yourself (heap-allocating RAII containers excepted), but the problem is the same.
I believe the point is that the minimum amount of training required to be of greater help than hindrance (i.e., net benefit) in an ICU and running ventilators is sufficiently high that it's not a small thing to spin up a cohort.

To my exceptionally limited understanding - and I would love to be corrected if I'm wrong - operating a ventilator correctly is not a matter of standing in front of a machine and watching a few numbers for problematic readings. That can be done by machines and computers. What requires training is everything else around it, which requires an understanding of medical protocols, anatomy, the ability to respond usefully to emergencies without being in the way, and so on.

Which is to say that this is not something that highly specialized and narrow technicians can be usefully trained for in a very short time at this particular moment.

That's not to say your idea is bad! It's definitely good and worth exploring in the future. There will be time to explore how to have smarter tools that can be used with a less general skillset can be developed. There will also be time to explore how to develop specialized and narrow curricula for such things - itself not a trivial task.
I think creating that virus is probably very challenging.
You may be a good CEO but is there any clause that prevents employers from firing everyone and taking the loan for themselves?
In my understanding, community colleges are usually public and nonprofit. Tuition tends to be much cheaper than at four-year public universities (which are in turn much cheaper than privates). They tend to run shoestring budgets -- certainly this contributes to the professor pay and work load issues you also mentioned, and probably also the parking fees.

As for the textbooks, I'm curious what you observed? I'm unaware of any university profiting in this manner. I am extremely aware of textbook publishers profiteering, as well as the occasional individual professor-author who shamelessly convinces the rest of their department to adopt whatever book they wrote.

But the most likely reason that the book changed, in my estimation, is that individual faculty members are often given leeway to choose their own textbooks. This has some negative consequences, but in my opinion it's a good system overall.

And, incidentally, if you want the best deals -- then I'd recommend that you neither buy your books from the school, nor sell them back to the school.

I only know about the transition to x86 and from what I remember the benefit was the same architecture as Windows. Since them OSX has gained a lot of market share. Moving to ARM is definitely a step backwards in that regard. I don't know anything about the previous transitions.

I don't think transitioning to ARM is a bad choice given the benefits, but a lot of serious (and casual) users are going to be very unhappy their programs aren't going to work after dropping $1k+ on a new computer.
