It's easy enough in elementary
treatments of probability to
say what is meant by random
variables X and Y are independent. And in both theory
and applications, independence
is just crucial. Well, what about
uncountably infinite collections
A and B of random variables being
independent? Also, random variables that are functions
of independent random variables
are independent, etc. The
sigma algebra generated by
a random variable, or a collection of such, is important
to be able to work with. E.g.,
just in the Poisson process, that
is, the vanilla arrival process,
need to talk about the time
to the next arrival being
independent of all of the past
of the process.

Except that the technicians used at the major overhaul base in China - by which I presume they mean the AMECO Beijing venture co-owned by Lufthansa Technik, a division of the well known major airline - are relatively unlikely to have FAA certifications not because they're incredibly lax, but because they're substantially more likely to have been certified by EASA (the European standards body) instead. Which has absolutely nothing to with language standards and absolutely everything to do with European companies not considering the FAA standards to be any more exacting or relevant than their own, and their US clients generally agreeing.
You know how to read, great for you. But that doesn't say much, as all AI that was ever attempted was trained and supervised by people.

Adam Smith, The Wealth of Nations, 1776:
"If a foreign country can supply us with a commodity cheaper than we ourselves can make it, better buy it of them with some part of the produce of our own industry employed in a way in which we have some advantage. The general industry of the country, being always in proportion to the capital which employs it, will not thereby be diminished ... but only left to find out the way in which it can be employed with the greatest advantage."

What's "successful"? If the Romans seem to have been more successful, how does that make you feel, compared to, if someone made a convincing argument the Romans were less successful?

Reading about the Byzantine Empire just now[1], I'd say 476 to 867 was one "dynasty", because in 867 marked the beginning of a Macedonian dynasty, which lasted until 1025. This would break down the Roman empire into dynasties of length not unlike Chinese ones. How do you feel about that?

Actually, it is not the parts of a plant that matters most, but the soil in which the plant grows.

Even such a crude instrument as tongue could tell the difference. It also will tell if a soup has been cooked with bones or not.

8 Joules is a really small amount of energy. I wouldn't be surprised if an average healthy child could put that much energy into a ball by kicking it. A quick back-of-envelope calculation says a 0.45kg ball (FIFA standard ball) traveling at 6m/s (~13MPH) has more than 8 Joules of energy.

From 1979 through 1987, I lived in what one called a "group house", with a population that started with four young men and ended with two. It generally worked well enough, though better with three or two than with four. There needs to be agreement on bills, chores, and standards of cleanliness (or, frankly, in our case standards of untidindess). I knew of at least four or five other households not far away, consisting of persons of about the same age and status.
This is far bigger than merely a trade agreement. It contains provisions that replace existing laws and may hinder democratic decision making. There are a lot of things in it that have nothing to do with trade, and everything with the rights of citizens.
Interesting product, but not really much of an improvement in speed if you have to do the page turns yourself.

The foot pedal for scanning saves a tiny bit of time, but it is still cumbersome to scan a whole book.

Also strange to emphasize MIPS CPU which should not be better than your average cheap smartphone ARM.

So, you are saving some time over regular scanner(been there done that), but it is still not practical for say 100 books.

If they had figured out a clever way to do the page turns this would have been a winner.
Cat's finally out of the bag, at least a whisker or paw. For anyone thinking about this, here is some more:

Advection implemented a tiered version of a cache eviction algo very similar to this single tier take since early 2000's. These graphs showing near optimal curves hold up in the real world.

When you have the one cache and window shown here, easy to see how to extend to layers (capacity/cost/performance) of cache. Harder to extend this across independent nodes across a global footprint of federated hubs, but that works too.

Crucial to get eviction and refill right when you're dealing with video sized files and limited cache pool. Pushed the VDN to innovate here well beyond what CDNs had or still have.

// Advection was a private label VDN (under strong NDAs and no sales and marketing) under the hood of brand name CDNs, with a VDN provisioning API. Several of largest premier certified streaming CDNs were Advection powered for their streaming certification, and many of the largest events throughout the last decade used Advection under the hood, even into this decade. The company was bootstrapped, profitable, and growing into the start of this decade, but HLS finally meant other CDNs could do video well enough they didn't have to have a parallel dedicated video infra, they could finally use their own edge, taking wind out of sails. While I stepped away several years ago, AFAIK Advection still offers boutique transactional video, able to track and control every user's stream in real time, enabling at scale a ton of very slick capabilities still behind some extraordinary VOD and live video business models, the ones that aren't just naïvely ad supported. Advection also innovated something we called "zero admin", now called devops. It had no sysadmins or support people, only devs.
Except if no config file is specified Redis defaults to binding to 127.0.0.1 instead of localhost? The docs even advertise:

Not to mention you can over-write arbitrary files by setting the dbfilename and config directory (Not sure why this is an interactive option to start with?).
In theory, yes. In practice, you get ~20% more bandwidth and almost no improvement in application performance.

>In what sense does a single data point represent a trend?

It doesn't. It's the other way around: a single datapoint can be congruent or incongruent with an observed and measured trend. This is the case with the present example.

You always have to be careful of craftsmanship, but to imply that there's no systematic variance as a function of national origin is disingenuous at best and insane at worst.

Again, I'm positively flabbergasted by the extent to which people want to play with words and run in circles around such issues, especially given the extent to which these problems are documented.

Also if you're not concerned about the 330fps legal limit paintball markers are manufactured to you can probably adjust the regulators (not just the velocity screw you mentioned) to get a much higher initial kick. Or possibly use your own valve, that tank must output around 400-800psi before the marker regulates it down to somewhere like 200-300.

And avoid feeding liquid CO2 into the marker. If there's a siphon tube in the tank it's fine that way up otherwise have the valve pointing up-ish.

> My mom has a foundry here in Slovenia and at some point she decided to outsource production of some relatively easy stuff to China, because it seemed cheaper.

Herein lies the reason. Chinese factories will manufacture things with as much quality as you want, provided you pay accordingly. Pay for a good product, you'll get a good product. Pretty much all of electronics you use, including the most high-end devices, was made in China. Most of the Western "Chinese = crap" stereotype seems to be because of Western companies, which pay for low-quality manufacturing.

Also, consider that this "less developed country" builds nuclear reactors, has a space program, and runs better metro lines than most of Europe. They somehow manage not to screw all of this up more than anyone else.

This is my understanding of how we ended up with today's flat UIs with less affordances even though many (most?) users dislike them. HN can tell me if I was told incorrectly.

1) GUIs in 1980s like MS Windows 1.0/2.0 had flat design[1]. The buttons were flat. No drop shadows. The "flatness" was not a deliberate design intention but simply the first iteration of a graphical UI to supplant text mode DOS console.

2) In 1990s, MS Windows 3.0/3.1 introduced 3-dimensional sculpted buttons. An visible improvement in UI affordances. Windows 95 further extended the 3D look where whole window edges, etc had sculpted look.

3) This era includes the Apple Mac OS X GUI ("Aqua
) that had 3D look and buttons had depth. It includes the Steve Jobs quote, “one of the design goals was when you saw it you wanted to lick it."

4) The zenith of affordances is reached with Windows Vista/7 "Aeroglass" where windows could cast translucent drop shadows on the desktop. Effects like that required heavier computation such as "alpha channels". Hardware-assisted (premium graphics card) was required. Desktop computing power (both cpu and graphics chip) to deliver all this GUI effects was not a big deal. This was the time period before "skeumorphism" became persona non grata.

4) iPhone/Android mobile phones come on the market in 2007/2008 with low-powered CPUs and precious battery life. Now, things like painting 3D heavy UI and rendering translucent drop shadows are seen as a massive extravagance. A waste of cpu & battery power. In 2012 Windows 8 and 2013 iOS 7, everybody removes the last 20 years of 3D GUI affordances and makes everything flat again.

5) To make the GUI consistent between mobile phones and desktops, Microsoft makes the desktops flat as well even though there is abundance of computing power. Therefore Windows 8/8.1 looks like Windows 1.0 again[1]. The Apple Mac OS X is also flatter but at least they kept the windows casting drop shadows.

What's interesting is that the marketingspeak from Microsoft/Apple/Google about "flat design" talks about it being "modern", "clean", and "fresh". To me, it seems like it's really all about the current limitations of mobile phone cpus and forcing a UI consistency to the desktop users. Basically, it's punishing the desktop users by enforcing the lowest common denominator across device platforms.

Hopefully, we'll get a new trend where everybody will go back to styling GUI elements with some hints of "clickability" without gratuitous skeumorphism. We just need some balance.

"More successful" here obviously means that their empire lasted a longer time, since that's what we're discussing. They may have been less successful in other ways. I don't really see what my feelings have to do with the discussion.

The Macedonian Dynasty in the Byzantine isn't quite comparable to Chinese dynasties. In China, a dynasty change, AFAIK, meant that one group overthrew another group and established their own nation, with its own laws and government structures. In Byzantine the change to Macedonian Dynasty happened as a result of internal politics (+ assassination). The nation remained the same; just the guy in charge changed.
