I wish antivirals are trialed with a different end point: reduction in viral load. This can likely be done definitively and a lot faster as well. Deaths caused by ARDS may be triggered by a virus but it doesn't follow that clearing the virus would cure one of ARDS. We really need a pill form of the antiviral and give that to people much earlier in the disease course. A pill is possible in this case as a Remdesivir analog https://www.statnews.com/pharmalot/2020/08/24/nih-gilead-rem...
thanks for the details!
"Can be" and therefore "must be because I say so" are two entirely different things.

It's still an option to just leave it alone. What is this obsession our culture recently has that says "Just because I CAN do something, I MUST do something"?
I would disagree in the specific case of AWS.

We have not seen such an egregious abuse of open source software with any other company. Most companies that make use of a large amount of opensource actually contribute a fair amount back.

Like hiring on the core developers or making a large amount of code fixes and feature development contributions.

Amazon does neither of these things.

I think that's nothing new and happens since humans started civilization. It's just now you can realize this within a lifetime.
Try it on a Linux system sometime then. The only saving grace is that the crap sputters "Skype" everywhere, so you get to imagine what a sad miserable existence it must be for the people maintaining that obviously inherited, hastily cloned monstrosity.

>> There is absolutely nothing wrong with knowing about, and discussing who it is

You should keep in mind that the investor may actually be innocent here. Imagine if the CEO was a sociopath who is both adept at manipulating public opinion and out to destroy the investor's reputation.

I'm not saying this is fact. I'm saying it's possible.

Outing the investor here will cause significant, irreparable reputational damage to the investor.

Given that the accusations are based on unsubstantiated claims, outing the investor is wrong.

Please don't underestimate the consequences of your actions. You may see it as just 'discussing some random topic on a forum'. But, doing so could be ruining an innocent person's life.
This is good news. But I think society is in a bad place already. This incident showed how vulnerable we are to the arbitrary whims of big tech (not just social media), who increasingly are becoming gatekeepers/editors/censors rather than providing neutral platforms. In this case, Twitter was caught red handed because of a long history of other 'hacked material' that has been allowed on their platform (https://thefederalist.com/2020/10/15/11-hacks-leaks-and-hoax...), but bias/deplatforming/censoring has become so bad that I would have not been surprised at all if they made no change to the policy and just continued operating with open political bias.

Generally the rule is that if it's hard, you can cut it off, because the mold will have only spread on the surface (think moldy cheddar cheese rind), but if it's soft, throw it out (think blue cheese).
They are global collectives of individual country-level partnerships (though in some countries they are allowed to be corporate entities rather than partnership entities).

Each country-level partnership is its own independent firm, and can generally choose to re-affiliate with another multinational "firm" as it desires. This actually happens quite frequently.

Generally, the member firms cross-bill each other at discounted rates. They make up for it through increased volume of work and/or more lucrative work.
I have often wondered if this can relate to whether someone is ‘good at math’

What if how it works is: we each see some math problems and symbols and make a guess as to how it works. If we are right, we decide we are good at math. If we are wrong we decide we are bad at math. Identity forms, then it is hard to revise your self assessment.
What makes me despondent is back in the 1970's 1980's much of the commercial work in the valley was about creating new technologies to empower people. Since 2010 it seems it's now mostly about exploiting people.

2010: Ubber, our app that ratfucks the taxi industry.
I think there might be a misunderstanding. I'm just talking about the multiplayer service infrastructure, not the whole game.

Despite doing a lot and having a lot of smaller moving parts, the mp infra is of moderate code size and build complexity is not a concern. The whole thing compiles in less than 5 minutes, and can be done with nimble (the package manager). We have a docker builder image that spits out the final production image containing the apps, and a docker-compose setup then runs those as needed.

Any kind of per-platform specifics are handled in nim itself (when defined(Linux): etc) and via nim.config/nims.nim, to link in platform libraries.
Then you probably want to know that your public servants are doing that, don't you? Rather than not know at all? Authoritarian would be you're not allowed to know at all. I'm pretty sure we tried that sometime in history, oh that just rings a bell... and it didn't work out so well then.

Or didn't you realize that this insanity cuts both ways?
It really doesn’t. Poor quality masks are questionable at an individual level but even if everybody just wore knickers on their head, that would have a gigantic effect on the spread on the virus overall.

From the email to Trusted Contacts users:

> Since then, we’ve built this functionality directly into Google Maps with Location Sharing

That's simply not true. You can share your location with someone else, but you can't request it from someone else _and_ automatically receive it after a timeout, in case they are incapacitated. This was probably 90% of the reason to use Trusted Contacts.

I understand that companies need to kill some products so others can thrive, but don't gaslight me into thinking that functionality exists where it does not.
1) When adding the 2^n'th element. Linked List would just append to the tail O(1) time where as ArrayList would double the size copy half the array and then add it doing O(N) amount of work. Still though amortized analysis of insertions in array list is O(1) because rarely do we double the size of array.

(30 times required to double the array for insertion of a billion elements).
There are lots of successful rationalists.

As an example, Objectivists generally accept the label of being rationalists. And the people at https://en.wikipedia.org/wiki/List_of_people_influenced_by_A... came under the influence of Objectivism before they were successful.

Some of the more prominent names on that list include Mark Cuban (Sharktank), Alan Greenspan (economist), Penn Gillette (magician), John Mackey (Whole Foods), Gene Roddenberry (Star Trek), Peter Thiel (Paypal), and Jimmy Wales (Wikipedia). And those are just ones who publicly talked about it. How many more achieved success but didn't choose to talk about it?
Yes, the value can either be copied or a reference to it can be passed and this determines whether it is pass by value or by reference.

It is clear that Java is pass by value but a little bit confusing since everybody is used to thinking about objects as references and this people confuse that these are different references than the ones in "pass by reference".

As to breakpoints this is more complicated and will depend on whether the code is interpreted or it has already been compiled.

In an interpreted bytecode (before JIT comes and compiles it) the buck stops at JVM as it is the one responsible for actually executing the bytecode.

Once JIT comes and compiles the code, the JVM looses ability to stop at a given physical instruction. In this case I think one of two things happen:

1. The function reverts to interpreted (bytecode) version.

or, 2. The JVM inserts instruction into the generated bytecode.

But I don't know JVM that well to tell which one is used, actually.

You'll see similar models in law firms. IMHO it's driven by two key elements in the business: An apprenticeship-like, up-or-out model for developing talent and a vested owner-operator class at the "partner" level.

These firms effectively operate as a collective for the benefit of the partner class. New partners must invest capital, ongoing partners get returns, and older partners retire with a terminal payout. Some partners may take on expanded leadership roles and get higher annual payouts.

The overarching legal structure is a sort of "modularization" to limit the liability of lawsuits and enable flexible operation. There is a usually a global partnership council that dictates universal operating norms and practices.

Again, fundamentally, it operates as a collective and international units support each other for collective benefit.

I don't have the actual study at hand, but it's cited in the book "The Righteous Mind".[1] They looked at independent communes[2] in the US in the 1800's, and 20 years after the founding of a commune, 6% of the secular ones were still around, as opposed to 39% of the religious ones. The latter had more things binding them. One insight: In religious communes, sacrifices (no alcohol, etc) correlated with longevity. In secular communities, there was no correlation. Over there, every sacrifice had to be argued about and justified. There was less thrash in religious communes.

(Just found the author of the study/studies: Sosis[3]

The sadness of my piano life is not my fingers but my dumb brain. No matter how intensely I practice and memorize a piece, if I step away from it for a week I'll forget 30% of it.

Curiously, my audio memory is very strong. I can hear music in my head clearly and in detail, even songs and pieces I haven't heard in years. This does not translate to "finger-memory".
Not entirely the same use case, but I've had some success displaying charts of time series data using Postgres's width_bucket function to group values into a histogram. width_bucket computes a histogram bucket for a value, which then can be used in a "group by" clause to group and calculate aggregate statistics for each bucket. This is pretty similar to the approach detailed in the post, but it's providing averaged values instead of a randomly sampled distribution.

If you want to display a line chart that is 500px wide, for example, you know you really only need 500 data points. You can treat this chart as a histogram, and compute a min/max/avg for each value. The chart could display the min & max as a high-low band, and if you zoom in further, adjust the histogram interval and requery.

This is what a query would look like with this strategy:

start_timestamp: The start of the histogram range
end_timestamp: The end of the histogram range
num_divisions: The number of histogram divisions

select
start_timestamp + ((bin_id - 1) * ((end_timestamp - start_timestamp) / num_divisions)) as bin_start_at,
start_timestamp + ((bin_id) * ((end_timestamp - start_timestamp) / num_divisions)) as bin_end_at,
average_value,
min_value,
max_value,
num_values
from (
select
avg(value) as average_value,
min(value) as min_value,
max(value) as max_value,
count(*) as num_values,
width_bucket(data_points.timestamp, start_timestamp, end_timestamp, num_divisions) as bin_id
from data_points
where
timestamp > start_timestamp and timestamp < end_timestamp
group by bin_id
order by bin_id asc
) t;

I'm interested to see if anyone else has taken this approach, and if there are any performance considerations I haven't considered!

That doesn’t follow. There have been many projects that I’ve seen forked internally because the original author didn’t know how to write tests, maintain performance, etc.

It is intended to do so.

It is not designed to do so.

Some politicians have become fixated on Section 230 as a remedy to what they feel is an injustice centered around these massive platforms, when what 230 mostly does is allow hundreds of thousands of small websites to operate without fear of legal liability for every single user comment, whether or not they do basic spam-filtering.

A solution exactly designed to make Facebook and Twitter less profitable would not touch the hundreds of thousands of other websites that gutting 230 would suddenly expose to liability. It would be much more tailored and specific to its purpose.

>1. Don’t wear masks

False. They said - "There is no specific evidence to suggest that the wearing of masks by the mass population has any potential benefit"

"In the community, we do not recommend the use of wearing masks unless you yourself are sick and as a measure to prevent onward spread from you if you are ill"

"The masks that we recommend are for people who are at home and who are sick and for those individuals who are caring for those people who are home that are sick,"

These are completely normal statements.

>2. Don’t close borders

False. The said "There is a “huge reason to keep official border crossings open” to avoid people entering irregularly and going unchecked for symptoms, "

"Certain containment measures will be appropriate, but widely banning travel, closing down cities, and hoarding resources are not realistic solutions for an outbreak that lasts years."

>3. COVID is not airborne

Please understand that airborne has a scientific meaning, and that is the terminology that scientists use. There is no actual clinical evidence of the airborne transmission of COVID.It is spread through large droplets. If it was airborne, those cloth and surgical masks that people wear would be useless, so you might as well not wear them.

Yeah, I definitely disagree that it is "virtually everywhere" or "cheap", but I definitely agree with the parent's overall point that it is way more ubiquitous these days by orders of magnitude. To the point where it enables a lot of things that were pretty much impossible back then, both in technical aspects and societal/job market aspects.

I think you're dismissing a lot of externalities here - IMO most egregious of which is ag-IP owners trying to claim ownership/control over other people's plants that have been pollinated by their GMO plants due to pollen drift.

I think a better analogy would be: you invent a new mousetrap, you offer it for $5 for only catching mice, but if it catches a rat they owe you $100. The user has to artificially restrict the fundamental utility of the product or else be subject to legal penalties.

"Life, uh, finds a way" and it's morally hazardous to restrict a customer's control of their physical property for IP reasons.
To clarify - that's why I specifically mentioned a modification, the CC-Attribution-Non-commerical license accomplished this in a non-software setting so I assume a sufficiently practiced lawyer could make the modifications to the GPL3 to specifically disallow usage in commercial settings - this would, after the modification, not be GPL3 anymore of course.

This does go against some philosophical decisions underlying the GPL license but IMO GPL itself is less free than BSD/MIT licensing and to each their own.
