Zanzibar is a global highly available distributed permissions system used within Google to power application permissions for things like Maps, YouTube, Calendar, Doc/Drive, etc. They wrote about it in a paper[0] that was widely discussed on HN at the time[1].

The service stores relationships between people, other people, and data, in a giant directed graph. There are primitives for querying and processing that graph to make permissions decisions. The majority of the rest of the engineering effort is spent on replicating the data globally and caching permissions decisions regionally and locally, since permissions don't lend themselves very well to sharding or siloing along service boundaries.

For the 5+ explanation, I wrote a little bit about my digestion of the paper and what the important parts are here[2].

> It's why public restrooms are always disgusting.

Not really. It's not a question of value that causes public restrooms to be less pleasant, but simply one of cleaning frequency.

Most people clean their own private restrooms/bathrooms/toilet (or have them cleaned) reasonably frequently. Increase the usage load for a public facility and you'd expect it to need to cleaning more frequently than a private one.

And so, one does indeed find public facilities with sensible cleaning intervals that are often no worse and sometimes better than private ones.

Most humans also have a somewhat instinctive distaste for urinating or defacating in a context where they can smell another human being (even one's own family!). Without very good ventilation, it's hard for a well-used public facility to avoid this, and that adds to the sense of "eergh, it's disgusting!" This is an issue, but again not one of "valuing free things".

The worst public restrooms I can think of tend to be the most lightly used, where it's hard to justify the cost of sufficiently regular cleaning, and things just get unpleasant, again without any question of values or cost-of-use.

Storing view time would make things easy, but might break on subthreads. You can probably just store all the comment ids in LocalStorage, and highlight comments that aren't in that set before putting them in there (or maybe put them in there only when scrolled to/past).
The question seems to be: should integration and differentiation be taught before matrix operations, or after?

IMHO, since linear algebra is largely a tool for solving differential equations, I think calculus should be taught first, as the fundamental knowledge.
It is not strange to find a linear equation solver at the heart of a nonlinear equation solver, though.
Topography gets in the way. Planes have a clear view of cell towers on the ground, satellites, etc. Planes never go through tunnels.

Owlet falling from nest or ready to jump from it and falling at the soil

You were most probably walking too close to the hidden owlet.

Father did what owls do when feel their owlets threatened, dive bombing from behind and attack directly to the head and neck.

Rabies is a mammals disease, fortunately can't develop in other vertebrates or migratory bird season would be a nightmare, so this owl was not under the effect of this disease. Is a typical nest defense behavior.

If it's useful, people who find it useful will use it and their lives will improve... people who don't find it useful won't use it and their lives will be unaffected.

If the deviation between these two groups gets too wide, you will recruit users because the facts on the ground will make the benefits obvious.

I think you're misunderstanding my statements. I said that being intelligent enough to work a job where I don't need to work with people saved me.

Absolutely. If you say something came before the universe, then you need a new word to describe that, and what was previous called the universe is no longer (by definition/need for a term to encapsulate all).
Personally I don't believe physics is yet equipped to answer such questions, nor can it be until we understand time (and so probably quantum gravity, due to relativity).

I agree with you, but I also kind of hate that "Why don't you just..?" has become so tainted, because it is a great question to ask if you want to learn more about the heart of the matter. What went wrong when the 'obvious' solution was tried is interesting!
Or, huh, just spitballing here, I suppose one could rephrase it as "have you considered..?" to ask the same question without the implicit assumption that the task is easy and the person being asked has overlooked something/is an idiot.
"Vaccinated people are less likely to be infected in the first place"

What is your definition of infected? Do you mean contagious?
That is a solved issue . It is the standard way of command line syntax and provides a common way of parsing command line for many OS. You can certainly do things “another” way but all it will do is break decades worth of work for standardization and good old fashioned common sense. Make things modular so you can expand in different ways.

In the USA, millions of people live in apartments or rented houses, maybe park on the street, and would have no means to charge their cars where they customarily park.

Yes, we've got ourselves up a tree without a ladder on this issue.
> That was GenX complaining that Boomers spent the 80s spending extravagantly through the federal government,

The Silent Generation was politically dominant in the 1980s.

Boomer political dominance was more a 90s and later thing, and the first decade of that was something of a period of relative fiscal responsibility.

> We still expect to receive less Social Security than our forebears, and there's practically nothing we can do about it.

Wel, demographically, yes, there's little GenX alone can do about it. It’s pretty trivially fixable, though.
> I see it all the time in other fields and I just shake my head. If you ever find yourself saying "Why don't they just..?" you almost certainly don't understand the problem.

A political corollary to this that I enjoy came from an old professor of mine- "If your political opinions require large amounts of people to be stupid or evil, you don't understand the issues well enough." (A rough quote, I don't remember exact phrasing.)

> While the army seems like a purely heirarchical system, it is really a hybrid system since interfaces heavily with the market systems which we call the military-industrial complex.

That has nothing to do with how things are run on a military base.

Besides, if you've got any evidence that the military worked better in a non-market system, like the USSR, please present.

> Markets tend to duplicate effort often in unnecessary zero-sum games.

Another word for that is "competition". Competition makes them efficient. Eliminating competition leads to gross inefficiency and incompetence, making things far worse than the duplication ever did.

The timeline many of you have guessed is off, I didn't want to comment on the exact timeline as I went back to work a few months back and I worry about retaliation from Amazon. Several of my friends have reached out that had no idea how bad it was. In the article I stated that of course I could have done better but my performance wasn't zero more like 90%, is that enough when you spouse had a terminal disease? Plus I was clear about it before I started.

My performance came into question after I talked to HR, coincidence? There are many instances at Amazon, documented, where an employee is pushed out when they are having personal issues. This push from my manager put me in a spiral that I am just overcoming.

Your script doesn't even do the same thing. You are importing a library that implements SMTP, which is missing the point.

The AWK script doesn't need libraries, so it can actually be useful in places where you have awk but not Python.
No, he is driving similar car with a lot of milage on it, especially these days with the crazy used car prices. If Toyota have made a basic mid 2000 corolla with no fancy anything I would pay for it much more than $2000, might install some aftermarket gadgets though but that would cost no more than extra $1000. The question is what would be the sweet price point for such a car and is it feasible to manufacture it for that price.

What do you think of Scott Aaronson's previous scepticism towards D-wave computers? I think it boiled down to them not doing a comparison with the best classical algorithms running on the best classical computers. Are your comparisons apples to apples?

I think what you wrote makes sense as a way of maximising the chances of producing a viable product. I suppose there aren't any guarantees that it will be competitive with bog-standard computers, but it might be a reasonable gamble.
Huh, Cruise got a permit for "between 10 PM and 6 AM" up to 30 MPH, while Waymo got no time limit and 65 MPH. Presumably Cruise's permit is actually for the 6 AM to 10 PM time period and not the 10 PM to 6 AM one!
Well, I guess it would be hard to scalp on of the closest managed inventory processes around. Thing is, only the last steps before FAL are real JIT, everything else is pretty much running on, more or less well amanged, inventory. Also, blaming the chip shortage exclusively on automotive and their mismanaged JIT is quite a theory, and an overly simplistic one.
Pattern recognition is certainly a major component of human cognition but is hardly the whole story. Solution of complex mathematical problems - those are not pattern recognition problems. Two quite similar equations may have radically different outputs for the same inputs, so that screws up the whole pattern recognition approach, doesn't it?

> But last week, Facebook revealed that it had manipulated the news feeds of over half a million randomly selected users to change the number of positive and negative posts they saw. It was part of a psychological study to examine how emotions can be spread on social media.

Doing such a study would be the first step in optimizing for a good emotional state. But it (quite understandably) led to an outcry which stopped it dead in its tracks.

I think that the key here is Cloudflare's approach: mainly working in the open - Akamai works kind of "behind the scenes", I don't think that developer working mainly for SMB is even able to try to evaluate their services, besides - just look at their website, it screams "big corps, talk to representative to learn about pricing"

I think that big disadvantage in this approach is that they are not getting "mindshare", in contrast to that people are able to use Cloudflare serivces even for themselves and as they grow professionally CF's constantly increasing amount of solutions is there as something familiar, approachable and ready to use.
Some vaccines can be used once. The risk increases in the next shoots, so you need to choose the time and do a risk vs benefit calculus.

Surely you can still find some old site from somewhere that uses it, but has someone actually used it even somewhat lately & what use case you had? For most cases where it made sense you would probably just use some static site generator and deploy different version if required. Or do the replacing during the publishing phase.
Reminds me of that anectode where the father would ask the son to take the clay pots and go fetch water from the fountain. He would yell at the son to not break the pots and slap him. When people asked why he punished the son before even going, he said: "What's the point of punishment after he breaks the pots?"
Awesome math
I think most people try to minimize visibility and impact of speech they don't agree with in whatever little part of the world they have influence over by e.g. verbalizing disagreement and counter arguments; not inviting people they strongly disagree with to things; not hiring them; not recommending their business; not letting them get near their kids; down voting; 1 star reviews; suggesting others do the same; embellishing stories to paint them in a more negative light. People in government positions can do all that legally, maybe with a few extra things to tip-toe around, but not much.

Protests aren't really a government provided platform, they're more a natural gathering of people that the government is explicitly forbidden from breaking up by using their extraordinary powers. Somehow, they are allowed to get in the way by requiring permits, but worse, they can and do use tactics to escalate protests into something where they can legally use those powers. Individuals can use a similar tactics e.g. instigate someone to take a swing at them so they can claim self-defense.

Even though I'm the one that brought up government hosted platforms for open speech, now that I think about it, the only example I can really think of is maybe town hall meetings. Knowing what a mess those can be, maybe that's why the government has been smart enough to not start hosting open online forums.

> Facebook was a PHP shop, so they worked on make it fast.

Tangent: Facebook's work on PHP was largely a technical dead-end. Their work on HipHop and HHVM was never accepted upstream, and eventually resulted in their forking PHP into a separate and incompatible language called Hack, which basically nobody uses outside of Facebook.

In the meantime, the upstream PHP project hasn't been standing still. The core development team has made a number of significant improvements to PHP performance. By 2015 or so, PHP 7.0 matched the performance of HHVM, and newer versions have improved upon that. (PHP 8.0 added a JIT compiler, for example, which can dramatically boost performance for some applications.)

Most companies already have the "apprenticeship" half-codified in "Junior Developer" versus "Senior Developer" distinctions or "Level Ranks" or other ladders like that. If you switch jobs mid-"apprenticeship" today in the software industry depending on who you interview with and how well you can negotiate you either "start over" at a low rank/level/job title or luck/bs into "skipping that step" and jumping to a higher rank/level/job. Standardizing that across the industry wouldn't necessarily be a bad thing for the industry.

Similarly, PE licenses would be so hugely worth it to the industry if it saved everyone time in "technical interviews", both interviewees and interviewers alike. How many collective labor hours as an industry are we wasting annually on "technical interviews"? For most classic Civil Engineering firms the "technical" part of the interview is almost entirely "Is your PE license valid and up to date?" "Yes." "Great, you're hired." The software industry would rather waste multiple hours (if not entire days) of wages of everyone involved instead, and it's rather sad when you think about it.
