Most non-fiction books that I've started and quit reading before 25% was because they felt like the content that could fit in a blog post had been stretched to over 300 pages.

I've found that summaries can give you quite a good idea of what the book is about in most cases. I read the full book if the summary interests me.
The property prices are crazy expensive when you start getting into the populated areas of Southern California. I don't know it could ever be done without spending huge amounts of money. I do think it would be great to link the Bakersfield and Fresno areas with both SF and the Los Angeles area.
That second one is terrifying! Did someone feed the system thalidomide and PCP or what? Some of them though, if I didn’t know I was looking for flaws, I would probably never think twice about them being humans.
Those are pretty different. Samsung's battery issue was a defect that they issued full refunds and replacements for, it was not a case of false advertising or fraud.

VW was fraud because they were promising emissions levels that were not accurate and they knew the numbers were lies. VW plead guilty to criminal charges, had executives evicted from the company, and was hit with massive fines in response.

If FuckJerry knew that the things they were promising in their marketing were not accurate, they should be hit with fines as well and corporate criminal charges. These sorts of acts of fraud would never be allowed on TV or other advertising media. For some reason we give companies on social media a pass. Fraud and other financial crimes that happen on social media by businesses should be punished like they are on other media.
C# lets you do that because C# doesn't have a way to declare a local readonly/final variable at all. I significantly prefer features that encourage the use of `final` variables everywhere that it is possible in Java.

I write C#, Java, and Kotlin in roughly equal measure. Each has its pluses. But the claim that Java's lambdas are worse because it doesn't let you--and this was a conscious design choice!--do something so potentially catastrophic and difficult to debug is an odd one.
Yeah, this bugs me. There appears to be no evidence at all that this was automatic braking other than "it surely must be." This stinks of clickbait.
I don't think "between any two numbers located on a line there must be more numbers" is the property you're looking for, since it holds for the rationals (all of which are, of course, computable).

Maybe "connectedness" is the notion you're trying to get at -- the real numbers are topologically connected, but the rationals aren't. If "A" is the set of rational numbers x with x^2 < 2, and B is the set with x^2 > 2, then the rationals are the union of A and B, and there is a "hole where sqrt(2) should be", so the rationals are disconnected. It's possible to define the word "connected" in a way that makes this notion precise.

A related notion is what's called "(sequential) completeness". The infinite sequence whose terms are (2, 2 + 1/2, 2 + 1/2 + 1/6, 2 + 1/2 + 1/6 + 1/24, ...), where the nth term is obtained by adding 1/(n!) to the previous term, intuitively "should" converge, since its elements get arbitrarily close together as n gets arbitrarily large. Any such sequence converges to a real value (this one converges to the exponential constant "e"). But if our number system is only countably infinite, there must be some sequences that get arbitrarily close together but don't converge. For example, if we restrict ourselves to rational numbers, this is a valid infinite sequence (every element is rational), and its terms get arbitrarily close together as "n" is large, but it doesn't converge to anything.

You don't even have to look to regional rail to see the complaints here - even in discussions like "should we expand subways or heavy commuter rail from the suburbs?" the loudest voices are often those of someone who has arthritis and doesn't think they could walk from a train to their office, or someone who has kids and doesn't think they want to deal with the hassles of a train, or, or, or...

...and yet somehow none of these people seem to be able to internalize the idea that better mass transit systems (and transit options in general) means less traffic for them to drive in, should they choose for whatever combination of personal or professional reasons to continue driving a personal vehicle on routes served by transit.

One side argues in favor of options to expand access and efficiency for society at large, the other side argues against options because they don't think the new options would benefit them personally. Even when you're talking about trains or bike lanes, classic American political problems are omnipresent.

As someone who grew up in Montana and North Dakota and has been an amateur astronomer from my early teens, I think you're being overly dismissive. Sure, sometimes and they're more of a faint white glow (which is pretty impressive just by itself), but in over two decades of semi-dedicated skywatching (before moving further south), I saw, with nothing but naked eyes, bright green curtains on multiple occasions, dazzling blue-white pillars all the way up to the zenith once, and red curtains twice. And that's living between 46 and 48 degrees of longitude where they're not that common.

If you're setting out on a trip to specifically view the aurora borealis, you'd want to make sure you're viewing from an area with very low light pollution, make sure you stay dark adapted, and schedule your trip around solar max. Under those circumstances, and given multiple clear nights, I would expect the odds would be excellent for seeing some quite breathtaking auroras.
As someone who moved from pure mathematics -> applied mathematics -> machine learning, perhaps I can offer a similar perspective to GP that explains why the measure theory stuff might not seem so useful to some people. Basically, in application you never need to worry about anything but your simplest case - that of a discrete-time, finite-valued process. All of the subtleties of measure theory, which occupy most of what mathematical measure theorists/analysts work on, are introduced when you assume you've got an infinity or a continuum somewhere in a model, and that assumption is never borne out in practice. Unless you really want to do theoretical math, you're better off learning only the aspects that relate to finite functions, i.e. almost none of what a real mathematician would consider to be "math". And that's not just out of laziness or disinterest - once you've restricted yourself to finite functions for empirical applications, you encounter a whole new realm of engineering difficulties to deal with, that theoretical mathematics doesn't touch. You've got to learn how to solve a different class of problems that aren't as purely logical, but are every bit as challenging.

To put it another way - think about all the pathologies you may encounter working with even a "nice" function space like L^2(R). You'll never deal with those pathologies in reality, because every empirical function is much better behaved - finite domain, finite range, and even if you assume a continuous domain, you can choose a model that only has a finite number of discontinuities, is Lipschitz continuous in between them, has finite total variation, etc. And that's why the hand-wavey, "intuitive" approach works so well if you're not a theorist, at least in my opinion.

Fyre was definitely a scam. McFarland was lying to investors, employees, and customers. He ignored professional advisors, and refused to cancel the event when it was clear a few weeks before hand that the products and services he had sold to people were not real. He accepted money for things that he had no way of fulfilling. That's a scam. Madoff may have done more scamming involving more money, but both were scams. McFarland was using later customers money to try to fulfill promises made to the earlier customers. And that isn't even starting to consider the real wire fraud he was committing the whole time behind the scenes, and the later fraud after he was out on bail.
Single piece of anecdata for you. I know the owner of a construction company. I asked him about the 3 unions he has in his company, and his answer was that he really liked the significantly better tradesmen that the union makes available to him. He’s fairly conservative, and I’m not sure he likes unions in general, but he’s found them to be a net benefit to his company, this is after having tried staffing with and with unions.

I appreciate the comment, and agree with your viewpoint. It's somewhat of an interesting area of thought of mine as well.

The difficulty is what counts as "outside" of the civilized world as we've built it, and if we found it, would we find ourselves in a crisis of the sort faced by Mr. Savage in Huxley's Brave New World? A natural man woefully equipped to survive in the unnatural world we've built around ourselves, but at the same time unable to return to living in a more natural state by virtue of what he'd become in trying to adapt?

Natural man facing unnatural problems he is powerless to solve due to his maladaptation to the world he has wrought, yet unable to escape or return to whence he came.

It's like some nightmarish Hotel California conundrum.
You pack a lot of fallacies into one sentence! False dichotomy, boogie man with the bonus of scare quotes. Mandating security updates for some amount of time after a product is sold isn't 'legislators defining security issues'.
It sounds more like an edge case though. I can't imagine all the data you need to store may or may not be the right format, so I wouldn't switch my database just because one or two entities need this.

For most languages and frameworks, using Postgres as opposed to sqlite is barely a higher cost if you’ve got the ops skills. I’ve yet to see an app that straddled this local/web-scale line where SQLite was a better choice or Postgres wasn’t the obvious choice.

There isn’t some massive cost to using Postgres instead, is there some desktop divide I’m missing here?

Do startups that raise from you tend to have other investors come on at the same time? If so, do they use similar terms or something completely different? If this doesn't happen now, would you hope that it would in the future (that is, that people would want to follow a round led by you)?

The general idea I've seen (for both SQL and NoSQL databases) is two apps never should write to the same database to ensure separation of concerns. Some API layer instead handles all write operations.

I've found that the tech industry often is. Trying to get managers to set aside time to iron out accessibility issues is like pulling teeth. Trying to get other developers to take it seriously is almost as bad. Often you count yourself lucky if the bare legal minimum is implemented.

Accessibility is very important, and if accessibility features are implemented well they'll often be useful even to people without disabilities, but do any CS/SE or code bootcamp programs take the topic seriously? I'm sure it must be taught somewhere, but it doesn't seem to be common at all. Can you even imagine 21st century university architecture department that didn't cover ADA compliance? That'd be unthinkable.
"data is data, it's either valid, or it's not. That's why the schema is about the data, not about the app."

This is not true.

The objective of the overall app/system (i.e. front/back/middle/DB/storage/services etc.) is to carry out some kind of business logic. A DB schema cannot fully validate stored data against the logic.

Otherwise we wouldn't write backend code, we'd just write a bunch of schemas and be done with it.

Let's use a crude example: a password. (Of course, we would never in reality store a password as a string in the clear, but just as an example ...). When a user sets a new password, we have to validate that it meets specific requirements in terms of format, and then some others rules which are more complicated such as: "can't be the same password as the last 5".

Those 'password rules', for example, cannot be encapsulated in the schema of the DB and yet must be applied in order for the data to be 'valid' from the perspective of the app, or 'overall system'.

The DB may only care that it's UTF and max 20 chars. But the system requires more validation than that.

Re: Your statement about 'one app writing data, and the other app not knowing what to do with it'. This is not true, because all apps operating on such data must understand it data in the context of business/logic context in which it was designed. Even 3rd party users of such data, via API's, must understand this data from the level of business logic - not merely 'schema validation'.

When you query data from Google Geolocation, the 'city' field may be a valid string of a certain length, but that's not very useful: it must actually be the name of a city! Any 'app' using this data must operate with the explicit understanding that this is in fact the name of a city - and not just a string that met a DB schema validation requirement.

That's nonsense. I have worked in remote northern locales for years as a geophysicist, and - the northern lights can be utterly amazing. You do not always need a long exposure camera to see them; they can be vivid, dancing and mesmerizing in reds, purples, whites and greens. Sounds like the sun wasn't active when you saw them. I have seen such incredible displays it was unnerving - with the entire sky shimmering in pockets of bright green whisps of light, and purple bands of light shining down upon me as I stood on a frozen lake on a cold, crisp night.

Just to give you the price, a return fare Shinkansen ticket from Tokyo to Hakata (Fukuoka) costs almost exactly $400 (44660 JPY). I did a random search for air fares for next week and the lowest ones were $250 return (was looking at an English site, so it only gave me USD). The Shinkansen takes nearly 5 hours, while the flight takes 2. Even when you account for the crazy amount of time ahead you need to arrive for a flight, it will end up being both nearly half the price and half the amount of time. Especially for business travel, there is no way for the Shinkansen to compete. I've actually done that ride once and really enjoyed it, but you have to be a train fan :-)
There's generally a lot to setup for DevOps, generally not something one accomplishes in an hour. On top of the many moving parts, there are numerous tools to know. Lots of settings and config to commit to git, secrets to manage, automation to implement. That's all before the application and databases to use.

In-memory or local disk databases aren't going to work for any real world use case, regardless of how small or simple your application is. Using Postgres or MySQL is barely more complex than SQLite, and it makes more sense to start with one of them than move everything over once you realize you aren't going to be running on your dev machine forever.

I think you misunderstand me (I may have worded my point badly). It's not that the reforms are toxic, or even anything to do with the reforms themselves. It's that the political landscape in California is often toxic when it bleeds over to the country as a whole. I don't mean this in the "California is just too liberal for middle America" sense (as many Californians seem to). I mean "California seems to have a level of corruption that makes successful reform nigh-impossible".

You can see this "toxicity" in, for example, the singular influence California (and Texas on the other side) have on K12 textbooks, and the synergistic relationship between huge California ag businesses and the Bureau of Reclamation.
I'm going to guess that the pictures are of hypergraphs. Hypergraphs are good representations of mathematical relations. Each vertex of the hypergraph is a domain, while a hyperedge would be a "relation", the subject of the book.

https://en.wikipedia.org/wiki/Hypergraph

For those unfamiliar with hypergraphs, they are very similar to classical graphs. Except hyperedges may connect more than two vertices together. (While normal graph edges normally only connect two vertices together) Therefore, you have to draw regions to represent hyperedges.
Regarding your first point, even simpler could be to store the json as string in sqlite as to avoid all the file handling stuff, but I would say that sqlite is already a popular solid application format ;)
