I also did quite a bit of benchmarking, and never saw any quadratic behaviour [0]. However, there is a floor for RSS and and elapsed time, but you would need to test assets less than ~1MB to see it. For assets over a limited range, the graph might look quadratic, but if you cover a large enough range you will see there are two regimes of behaviour.

> I think one could study at much lower cost in China, Russia, Eastern and Central Europe. They have now courses in English, and have become the new hub for medical education.

Cost is cheaper, yes. Quality varies a lot across the country. Some countries are doing better than others. But medical degree is still not easily convertible, so if you study outside the US, but practice here, it's not simple. Language is not the main issue, different approaches, different standards, etc.
It's not a fantasy land. It's called Sweden. Estimates are placing the actual IFR at about 0.5 to 0.3%. For comparison, the seasonal flu averages 0.1%. A country in the middle of a coronavirus epidemic looks mostly like a country that's not in the middle of a coronavirus epidemic, save for 3-5x as many people dying of coronavirus as the flu. Saying that it's not wise to devastate one's economy over such an illness is a perfectly reasonable position.
This information has been known for THREE WEEKS or more.

It is criminal how overly conservative the FDA is being with potential COVID treatments, especially ones that have fewer side effects than Chloroquine.

Ivermectin + Doxycycline was suggested as an alternative to Chloroquine + Z-pack because it does not cause cardiac issues and can be given for home use more easily. Meaning people could start treatment before going into the hospital.

The risk management at the FDA is criminal. When a pandemic is raging and you have drugs that have been studied for 30-50 years the risk of allowing doctors to use their own judgement is so low, when the benefit could be very high.

What if it prevented even just 10% of hospitalizations? How many millions of dollars could be saved with a $3 drug?

Instead the FDA sends out a letter last week telling doctors not to treat Covid with Ivermectin. Insanity.

Individual doctors should be allowed and encouraged to try any well known, throughly studied drug when we are bleeding trillions of dollars, millions of jobs, and thousands of lives.

We have reached a point where overly conservative risk management is literally killing people.

> death numbers and hospitalization numbers don't lie.

Death numbers are close but still have some uncertainty. New York for example is reporting much higher than usual numbers of people found dead at home. Not clear if they have been tested, if they are victims, or if maybe they had unrelated medical problems but couldn't/wouldn't go to a hospital under these circumstances.
Many such trials are research and require extra planning, staff, researchers and equipment. Tests need to be rigorous, documented and are coordinated and shared via WHO among all countries.
We can't tell anything from the article.
* We don't know how many people were tested.
* We don't know how many people tested positive.
* We don't know the false positive rate for the test.
Agreed, SQL has really nice clauses. from, select (sub selects), expressions, joins, aggregation, sorting, limit/offset.

I tried going through graphql but found it quite hard to grok. Plus that graphql is different language, that needs more plugins to then go into sql. It's really hard to beat the expressivity of SQL.

I do hate writing SQL though, you miss a comma and it barfs at you. The error messages aren't very helpful either.

I'm working on a web mysql admin called BoomAdmin (like phpMyAdmin but invented for 21st century). https://github.com/nojvek/boomadmin (open source)

The core difference is there is a SQL block builder UI. It's 10X faster than writing a SQL by hand since you're mostly just clicking buttons and selecting fields. The front-end sends a json AST to /api/select which then compiles it to raw SQL. It's a really nice experience.

The vision is to build really nice editing, query & visualizing experience for SQL-ish backends. There are now nosql databases like couchbase that support SQL via https://www.couchbase.com/products/n1ql

It's called GraphQL not JSONQL ;)

I do see your point that for many applications you want the result in a tree, not in a list of rows. I think there should be a relational query language that lets you map from one schema to another schema (or potentially a subset of an existing schema), allowing the result to be another graph (or database in the parlance of RMDBs)

For the most part, there's nothing surprising here. Because we know so little, and searches for evidence have been driven by preconceptions, and outright superstition.

This jumps out as the key observation :

> By contrast, Mina Weinstein-Evron, an archaeologist at Haifa University who co-discovered the Misliya Cave jawbone suspects that the recent findings are H. sapiens but agrees that the story of anatomically modern human dispersal is still far from clear. “We know nothing. We have a dot of evidence here and a dot of evidence there,” she says. “And then we use these big words like ‘migration’ and ‘dispersal.’ We talk as if they bought a ticket. But they didn’t know where they were going. For them it was probably not even a movement, maybe it was 10 kilometers per generation.”
(I work at YC)

There are a couple of things in this comment that aren't true, and I want to respond to make sure that people reading it don't come away misinformed.

YC does not distribute lists of "top companies" to investors, around demo day or at any other time. Quite the opposite - we take great pains to ensure that investors at demo day see all companies as equally as possible.

About other venture firms being investors in YC, it is true that Sequoia was once an investor in YC's funds, but that was a decade ago. We haven't had a venture firm as an investor in YC in many years to ensure there is an even playing field.
COVID-19 isn't caused by this virus (Influenza A), it's caused by SARS-CoV-2.
I remember an interview with an archeologist that studied the Nazca Lines. She said one year she had a grad student who was a farm boy. He showed her how to draw a long straight line by setting up a stick a 1000 feet away and then just walking towards it while dragging a another stick behind him. It was perfectly straight.

It's basically the same as the old draftsman's trick for drawing a straight line.
Is this maybe then analogous to the essential and accidental complexity premise that Fred Brooks put forwards?

It may be that in painting the cost of accidental complexity can be reduced greatly but in photography due to necessary post-processing there is less on an opportunity.

That doesn't mean there isn't an opportunity here. Being neither a photographer or painter I am most likely not the best person to comment however!
Somewhat infamously, Intel once sold some low-end CPU models primarily to PC OEMs and then turned around and offered end-users a $50 software patch to unlock the other half of their L2 cache. Meaning that the whole cache passed QA even for the low end parts and half of it was disabled purely to prop up the price of mid-range parts.
Command+F 'Trump' -> 0 results

They seem to be ignoring the massive elephant in the room, where there was political intrigue and a personal vendetta interfering in what's supposed to be an apolitical process[1].

> "I'm getting tremendous complaints about the contract with the Pentagon and with Amazon; they're saying it wasn't competitively bid," Trump told reporters on July 18. "I will be asking them to take a look at it very closely to see what's going on because I have had very few things where there's been such complaining."

The fact that DoD officials were gagged from providing truthful testimony should automatically result in the results being thrown out. They wouldn't be gagged if they were going to say something helpful to Microsoft.

More information about S2[1]:

[1]: http://www.solstation.com/x-objects/s2.htm

It's really quite a spectacular object: a star in a highly eccentric object, whipping past at the black hole at over 1% the speed of light, in a gravity field so intense time dilation from curvature alone is 3%. It's a bit of mystery why it doesn't get torn apart by tidal forces, actually, and it's probably just barely small enough to stay together. (Because any excess mass would have been ripped off long ago.)

They've been tracking S2 for decades (it has a 15 year orbit) but they only now have enough data to confirm the precession.

On a historical note, the precession of mercury[2] was one of the early puzzles/confirmations that led to widespread acceptance of general relativity. Gravitational lensing and red-shift can be explained equally well by quasi-Newtonian field theories, but precession is extremely difficult to explain in flat space.

Should I continue reading a book that I don't understand?
Hi. I'm a spanish guy that don't speak a full dotted English. I'm interesting for learning C lenguaje. I have done some online courses but before I start in the C++ camp, I'm trying to read some books about C. I have started with Modern C, a free book that i found in the GitHub book's list. Although I have learnt the basics of C (I know basics about I/O libraries and things like FILE * in haha) I don't understand much about the book. I had seen that it is a book for begginers, but for me is very hard to read a single page. First because of the English (that is not a big problem because I only don't understand a few words that I can quickly search on Google) and second because of the difficulty for me. Should I forgett the Modern C book and try to read another book? I mean, another book might be more easy and after have read that book I will might read Modern C. I'm 17 years old and obviusly, I'm not in the university. I know PHP, SQL, JS, (html and css) but I want to learn C and C++. I would preffer to learn from books in English because most of the deep things on this world are wrotten in English. Thanks for the readding and sorry for my bad English. :)
What separates drivers from phone/laptop users? Certainly not techies vs normals. It would seem to me that both cohorts are capable of, and potentially interested in, deciding between "shorter days but more years" and "longer days but fewer years."

May I ask what's wrong with using xxd? I don't have an opinion about C, but C++ is already pretty complicated, and adding features to the language when there are already well-known solutions doesn't seem wise.

(For the record, I'm aware that there are size limitation when using xxd, but there are also other solutions).

Wife tested positive and was in the hospital for 4 nights. My symptoms were mild so I was never tested. We presume that our baby had it too. His symptoms were the mildest but he also took the longest to recover. All of us recovered and feel fine now.

I had a fever for 3-4 days, body ache for about a week, and a cough for a couple of weeks. Didn't take any medication. For me, it was not even as bad as the flu.
The point was more that the "typical incubation period" you are citing seems to be wrong, and not the presentation of the disease. Obviously yes, we'll know more with more data, but that's not an independent variable you're introducing.
Generally, SCADA, AGC, and any EMS software updates should go through multiple lower environments before getting into a production environment. Even critical patches would spend a little bit if time in a lower environment prior to production.

Ask HN: How to create systems and not goals?

DoD officials are barred from answering questions about White House influence on the decision owing to its assertion of "presidential communications privilege"[1]. This is, quite simply, a confession.

Nothing is solved by believing that the administration is somehow different than the dozen or so near identical leaders in other countries: that somehow this one uniquely is not pressuring companies hostile to it (in spite of the fact it has already publicly done so[2][3]).

And while a deferential Amazon might be bad, it's really something you'd want to nip in the bud before Google or Facebook become too terrified of the white house.

FUD. There are several critical flaws in your analysis (disclaimer: I'm an enthusiast, not a cryptographer).

> The ratchet protocol that that approach relies on requires both ends to be online at the same time.

This is simply untrue, and in fact the very point of the ratchet is to support asynchronous messaging. The next ratchet's key material is sent alongside a message encrypted with the previous ratchet-derived shared key.

> since the server has to be involved in allowing offline messages to work

Sure, for some definition of "involved". But the relay server in the Signal protocol absolutely does not need to be trusted for offline messages to work, they are end-to-end encrypted.

If you don't bother to verify the security number, then you need to trust the identity server, but that's out of scope for the protocol. Verify your security numbers!

Strongly disagree. The slots will immediately book out to the last available date. So if slots are available in 10 days that just means that everybody has to wait 10 days for their delivery. Increasing latency doesn't increase throughput.

The UIs are terrible.

Indexing encrypted email -> difficult. Do it on the server-side and you're essentially storing the email in plaintext on a server -- you might as well have settled for hop-by-hop encryption, which is what MTAs basically try to do anyways.

Multiple devices -> yeah, that's tough too. They need the private keys. They need to keep their own indices.

End-to-end encrypted email is likely not workable. I'd settle for having hop-by-hop secure email, with a "make it secure" button on send so I can have MTAs bounce when they can't forward securely, and a "secure"/"insecure" label on inbound email that captures whether the whole path inbound was secure or not.

Another thing is that end-to-end security in general depends on introducers. CAs, etc. Meaning that the security that users who don't understand these things (99% of users) have in mind is just not what they're ever gonna get in most or all cases.

It works a little better - it tells me when "the security code" changes. Thus an unnoticed mitm attack has to begin at the beginning of the conversation or at a plausible change of the device. The attacker must be ready to intercept the "you got a new phone? Which one did you get? How broke the previous one?" and keep the conversation plausible.

There are certainly targets where such attacks are relevant, but for many it's quite good.

Thanks for your response. We are more just concerned about being dropped over the large number of charge backs in a small period.

So much so that we are actively implementing a new provider as backup so we aren’t stranded if we get cut off.
Thanks for the pointers - I'd looked at that, I think, but missed the add-rule bit.

But to be clear, it's easy to set up the validating service so that it accepts a token with expired timestamp as valid - it's the default to not check the timestamp if present?

A token without timestamp will never be valid if a rule for checking timestamp is added in the parser?
