>That is, if you teach the students to "type" all those fractions (e.g., 1/3 of this blue table, etc.),

Sure. You can certainly ad hoc extend the analogy to bring it in line with the mathematical rules. But at this point, you do hit a higher level of complexity. Your simple analogy is gone and you're slogging through the weeds. That was my point. Analogies are flawed. The teacher started with a very simple rule that worked well and communicated the ideas under certain constraints and then those rules were extended in a logical but incorrect manner by a fourth-grader ... and now the complexity that was hidden in the abstraction is leaking out.

Your explanation is more confusing to me and wouldn't be grasped by the vast majority of fourth-graders. At some point, simply stating that fractions have different rules is the most simple (and correct) explanation.
I agree, the question of how to deal with high uncertainties is definitely task dependent. In your example of a self-driving car the answer is not clear. However, for many other tasks its entirely reasonable to have the AI make decisions and then pop it out to human review upon high uncertainty, or just not act on it. In tasks like this AI can be the primary task-doer with the human as the backup.

So that's round-about but going to "My Books" (which seems to be their new "library") downloading it gave me a .acsm file which can be opened with Adobe Digital Editions software which will then download the epub. So it works, but surely there's a saner way!! Also note that you can't download the book from the book's page (which only points you toward their app), but only by clicking the dropdown menu on the My Books page.

Thanks for pointing me to it!

ZFS Focus on Ubuntu 20.04 LTS: What’s New?
TerminusDB (open source graph DB) had a 'Show HN' article a couple of months ago - since then work has focused on the delivery of collaborative Git-like functionality for the DB. I thought the community might be interested in this white paper (a bit CS heavy, but this is probably the right place for that).

We want to enable the types of CI/CD used extensively in software engineering to be used with data. Terminus 2.0 allows for the whole suite of revision control features: branch, merge, squash, rollback, blame, and time-travel. We are building a TerminusHub server linking TerminusDBs and allowing users to collaborate. The idea is to build a decentralized tool for version control of structured data. It will be offline-first, reliable, private, efficient and collaborative, but also to provide a Hub server if users don't want to spin up their own.
This does nothing to elucidate the problem. 1/3 apples + 1/3 oranges could be 2/6 fruits, or 2/781 fruits, or any other number you want. In normal mathematical notation, 1/3 is interpreted as 1/3 of 1, and in that case 1/3 apple + 1/3 orange is 2/3 fruit.

And of course this only works if 1 apple = 1 orange = 1 fruit, which means that they are the same unit of measure, or, equivalently they are of substitutable types. It's even debatable of it's correct to say that 'if I have 1/3 of an apple and 1/3 of an orange, I have 2/3 of a fruit', so depending on what you want to do with your apples, oranges and fruit, your hierarchy may in fact break Liskov substitution. For example, if 1 apple + 1 orange = 2 fruit, so 2 fruit - 1 apple = 1 orange, so 1 apple = 1 orange, which is not true.
People are using Android, just not GMS.

It is funny, that GMS itself is yet another layer built upon Android.

How is it different that Tencent distributing this layer via WeChat, other than Google bundles this layer through GMS?

Tencent does have its counterpart of GMS, like piece by piece, but that approach isn't winning against WeChat either.

Apple doesn't care about the open web. They've repeatedly tried to push encumbered media formats and not supported open ones, and they've held back implementing standards that pose any threat to the App Store. The fact that iOS doesn't allow other browsers at all is detrimental to the web.
I agree in that perhaps entities with a public platform (in this case, literally the internet domain) should be compelled to provide reasonably equal access/equal speech rights to everybody.

However, the law is not in that rationale's favor. US courts have repeatedly rejected the argument that private companies are state actors subject to the 1st Amendment [0].

The reality is that the internet is governed almost entirely by private companies.

How to fund a freedom dividend with a retirement portfolio
What is the end game for that strategy?

Last time I ran the numbers, they said we’d be in the current holding pattern for 27 years.

Here is how you can run the math:

1) Divide deaths per day by 0.005, or use an epidemiologist’s estimate of new cases per day.

2) Look up the world’s population.

3) Divide the two, and multiply by 0.8 (which is a good estimate of the necessary herd immunity fraction). Convert from days to years.

While you’re at it, look how long flu vaccines last until the virus evolves immunity, then look at how often coronavirus changes relative to the flu.

Edit: I agree with the bits about having the government pay salaries directly, and that early action can effectively stop pandemics before they start.

They have a list of domains to exclude from their so-called tracking "protection" and that list contains Google and Facebook. I wouldn't call that attacking by any means.

The Facebook Container is absolutely pointless when you account for fingerprinting and IP address tracking.

> sensible max budget defaults for new accounts to prevent surprises.

Amazon, in my experience, has issued organizations a one-time credit in cases of surprise bills.

The bigger crux of the issue, is Amazon has democratized CapEx into OpEx, and it's too easy to be ignorant of the details of infrastructure planning, which is rolled into AWS pricing.

Before AWS, IT teams had to plan for and estimate costs prior to procuring hardware. This is no longer needed with ondemand, programmatic infrastructure.

Engineers, who (reductively) focus on solving business problems with code, aren't necessarily thinking about the costs of deploying their solutions, the way Ops and IT would be.

> Traffic appears at core routers because it already gets send there by peripheral routers as a gateway. Sharing routing information between peer routers is not unsolvable nor likely onerous. Strawman solutions (flood constantly) are being deliberately dense.

If by "sharing routing information between peer routers" you mean that, when a router learn of a new host, it shares that information with its peer routers, which then share that information with their peer routers, that is flooding. Without flooding, the traffic would not appear at every core router, which means most routers would not know of your host.

> I suspect because, folks are so very comfortable with what they know, and so very unwilling to extend themselves.

I once seriously considered how to make an Internet-scale non-hierarchical routing protocol, where the host identifier was a cryptographic hash of its cryptographic public key. The reverse path is easy; once A has successfully sent a packet to B, all routers in the middle know how to get from B to A. The forward path (from A to B) is the hard one. Every router knowing every host is non-viable; consider, for instance, what happens when my phone roams from the WiFi to the LTE and back (which happens many times per day) - if every router had to know of that change, for every roaming phone in the world, it would be enough to overwhelm all the links between them, not to mention their CPUs. I came to the conclusion that the amount of propagation of the route updates must be limited for it to be viable, so having every router know of every host is not possible. Either the routing information must be summarized somehow (which is what the hierarchical routing used with IPv4 and IPv6 does), or some other way which does not involve the routers (for instance, path routing, like MPLS) must be used.

That is, I'm not rejecting your idea because I "feel comfortable" with hierarchical routing, I'm rejecting your idea because I've already given it (or something like it) serious consideration, and found it harder than what I had initially thought.

In general, I think neural networks really struggle with np hard problems. Current state of the art is bottlenecked wrt to even subtle generalization. The strong baselines have been variations on the pointer-network architecture for some time now. Even though they can do reasonably well on restricted problems (e.g. instances of sat/traveling salesman with fixed # of nodes), they struggle to generalize to instances of the problem with variable # of nodes - not to mention varying the problem itself. Some popular approaches also incl. applications of Graph CNNs & reinforcement learning. Don't really have much more than a cursory idea of the current directions though.

To me, more exciting is some kind of joint collaboration between modern ml systems & formal solvers.
> Do you think this actually hurts sales though? I’ve always been of the impression that the vast majority of people pirating wouldn’t have bought it anyways.

I'm not sure how applicable it is for books, because generally prices are more uniform for books than they are for software, but in the case of software I wonder if the ones who lose sales to piracy are the makers of more affordable software?

Imagine a world where piracy was effectively impossible for most people, and you want to do some occasional image editing. You look at Photoshop and it is way out of your budget. But you don't actually need most features of Photoshop. You find that Pixelmator Pro can do everything you want, and at $40 you can afford it and it is a good value. So you buy Pixelmator Pro.

In a world where piracy only takes a little time and effort you pirate Photoshop.

In both scenarios Adobe doesn't get any of your money so we can't say that pirating Photoshop in the second scenario cost Adobe a sale. But it did cost Pixelmator Team a sale.

In general, I suspect that the main effect of piracy is to change our allocation of spending within certain categories or groups of categories, without changing the total we spend in those categories.

The entire premise up front is false and probably a primary culprit. Expecting ML to do things it can't yet by extrapolating from what it can do today (after reading current capabilities through a filter of marketing hype):

>Today's work in artificial intelligence is amazing. We've taught computers to beat the most advanced players in the most complex games. We've taught them to drive cars and create photo-realistic videos and images of people. They can re-create works of fine-art and emulate the best writers.

Today's work in ML is amazing.

> We've taught computers to beat the most advanced players in the most complex games.

Not true. You can spend a zillion dollars on self play to get an AI superhuman at games simple enough that you can simulate at many many times real life speed, but we're just now learning to do games like poker, which intuitively seems less intellectual than Go or Chess, but so does starcraft and that came after those other games. In ML, placing tasks in order of achievable to currently impossible can be really unintuitive for lay people.

> We've taught them to drive cars and create photo-realistic videos and images of people.

No again. We're getting there with cars, but it turns out that it's really really hard. Harder than playing superhuman chess! But people who play chess better than computers can drive cars better than computers. Weird, right? Again, in ML, placing tasks in order of achievable to currently impossible can be really unintuitive for lay people.

We can make photorealistic pictures of people, but we're sorta limited (it's complicated) to faces at high resolutions and just really really really recently getting them without weird artifacts. But the face is the most complex part of the body, right? So the rest should be easy!

> They can re-create works of fine-art and emulate the best writers.

I was always a fan of dimensional analysis as it tickled "puzzle solving" aspect of my lizard brain, but if it were introduced via nuclear blast analysis in my classes I bet it would have grabbed a lot more attention.
I should have included the context that my notes pertain somewhat more to Postgres than other database systems; "USE" may work for MSSQL (and others) where the database is treated as more of a namespace concept, whereas Postgres requires a new connection per database. If you've got 1,000 databases on a Postgres cluster and are limited to 1,000 connections, there's going to be a tradeoff in connection setup latency vs. connection concurrency vs. efficient resource use. Or, spend time writing a dynamically weighted set of pools? Oof.

A parameterized query like "SELECT * FROM post_categories WHERE tenant_id = ?" would very much be cacheable by the query planner. Stuff like "does tenant_id have an index? is it worth using the index based on its histogram? are those index pages already in memory?" etc.

You want to fix the Internet?

Easy. Start by releasing a browser with built-in uBlock Origin and a bunch of other extensions that make the internet better (strip utm_* crap from URLs, etc).

You know, actually do something instead of merely pretending like they currently do. Their current "tracking protection" is an absolute fraud when you look at the list of domains it whitelists explicitly, and both Google and Facebook are in there. The opt-out telemetry (illegal under the GDPR, should be opt-in instead) as well as the telemetry for those who opt-out of telemetry (yeah you heard that right) is just the icing on the cake.

My preferred way is to pirate everything, and support after the fact, usually by buying copies to give to friends (though more than once it was just "buy the DRM version and never touch it because nothing else was easily available").

I like this because I make sure to support things I enjoy, rather than buying something and finding out it was not as good as the reviews made it out to be. It is a product of my entitlement, sure, but with the wealth of free content available, I can't justify spending money up front anymore.
Afaik, this is the norm and not the exception.
Eww, GPLv3. Not even LGPL.
I went through a phase where I was buying and selling job lots of books in the hope of striking gold (spoiler: you have to go through a LOT of books, and you'll make less than minimum wage). I ended up selling pallets of excess books for pulp - the paper of the books were worth more than the content.
I can find a specific reference, but it they made a bid deal of being DRM free a decade ago.

A question for you (and everyone): how important do you think it is that the algorithmic discoverability be married to a single platform/aggregator? What if you just had better algorithmic discoverability across all writing on the internet, regardless of where it's hosted?

I get that that would miss some of the benefits you mention (shared comment logins for example) but I'm wondering if people think it would capture 80% of the same benefits or, like, <50%. And I don't think for the discoverability to work there's any innate reason it has to be restricted to a single blogging platform.
> With respect, I don't see where you're seeing an accusation of bigotry; I certainly didn't intend one. You agreed hormone levels are the issue; how is "if hormone levels are the issue" a veiled accusation of bigotry?

It suggests that the issue is something else, not what was raised. It reads as an accusation that the hormone issue is just an excuse for an other agenda. If that wasn't your intention I belive you, but it can be easily misread.

> If the goal is to see "natural" talent apart from doping, how does forcing athletes to take hormone suppressants satisfy that goal?

I think the goal is both finding what humans are capable of, but also rewarding human achievement. If a world record can only be broken or a race can only be won by someone in the top 0.1% of testosterone levels then 99% of people have no reason to even try to compete.

Training at a high altitude is still within the reach of natural human ability, while taking hormones isn't. Although I would support the idea that everyone can take as much testosterone as you need to get to 1200 ng/ml (or some other reasonable threshold) but not more.
I also didn't encounter it until I was relatively older. Our school has been pushing to introduce more rigorous language and definition in our 7-12th math program. For some students, it really seems to help. For others, it's really hard.

Blockchain has a real use, in that people use it and it lets people do things they could do before. Blockchain has an expectation problem, its most breathless promoters promised things that no technology can deliver and then when it fails to deliver on those very high expectations it creates the impression that Blockchain failed. Blockchain, for instance, can't fix journalism, but it shouldn't be expected to, anymore than the internet or databases could be expected to "fix journalism".
