I have the opposite opinion. Why would anyone invest in Uber over Lyft?

Uber has a brand people hate, and is losing market share to Lyft. They have room to shrink.

Meanwhile, Lyft has a brand people love, is taking market share from Uber, and is starting to expand internationally (Canada). They have room to grow.

That's an excellent point. When humans are taught chess, we are initially taught the value or power of the pieces. The queen ( being the most powerful ), then rook ... all the way down to the pawn. Stockfish is programmed to know the value of the pieces. But Alphazero isn't taught anything but the rules. If it has any values for the pieces, it would be self generated though I doubt it generates any values for the pieces since it really doesn't need to and the value of pieces varies depending on the position.

AlphaZero does seem to have a style which favors positional development over value. It seems to choose pattern over material.

I wonder what would happen if one set of kids was taught the value of the pieces and another set weren't taught the value. Would one group be better than the other? Is knowing the value of the pieces a help or an impediment to developing your chess skill, especially at such an early age?

Of course, we can use i32 directly, but when project has hundreds of enum's, when enum's are constantly updated, when different crates are using different incompatible approaches to represent repr(C) enum's, it hurts. Rust compiler can pack Option<NonZeroU8> into single byte, so it can do that for repr(C) enum's with e.g. `Other(2..255:u8),` variant too (see my proposition above). Technically, they are not different, just have more specific cases.

As someone else who's run a lot of interviews including tech exercises (as much as I hate the typical way they're done, I haven't been able to eliminate them everywhere I've worked), I have the same experience as the parent commenter. Yes, even with "good" statically-typed languages like $YOUR_FAVORITE_LANG_HERE.

Candidates using those languages can often sketch out the right algorithm and the structure of what the program would look like, but under time pressure have trouble producing something that actually will compile and run properly (and as much as I want "showed they got the right algorithm and how to do it" to be a pass, it isn't always). The "executable pseudocode" nature of the popular dynamic languages is a big advantage there.

It's definitely even worse for C#/Java style languages (though C# is better than it used to be), because of all the heavyweight design pattern stuff you need to implement to do things that are just natural idioms in the dynamic languages. But it's something I've seen happen in a broad range of static languages.
What would be a components of an "ideal" solution? I'd love to hear improvements or corrections to my assumptions.

1) Free to view all approved papers (possibly run by a non-profit and funded by grants around the world)

2) Establish reputations for scientists (giving scientists access to future grants)

3) Peer review handled autonomously (submitted papers are automatically distributed autonomously by the system to other scientists in the related field with a high enough reputation)

4) Easy searching for articles (articles have semantic structure, are categorized by author, title, subject, citations, etc.)

5) Removal of "scientific silos" (all articles published to the same site, categories define content rather than publishing brand)

This talk of "information war" is extremely creepy. IW is unfalsifiable and indistinguishable from legitimate popular dissatisfaction, which is a much more likely explanation for recent political outcomes. No, the existence of a few foreign-sources social media posts is not evidence that recent political results differ from the genuine will of the people. The results of elections and polls do, in contrast, constitute evidence that the people, as a whole, feel a certain way. Macron has an approval rating of 17%. Are foreign agents manipulating 83% of the population?

While "information war" is bogus as an explanatory or predictive theory, it's an excellent pretext for censorship, especially since it seems to be brought up whenever a political outcome disfavored by the elites occurs. Followed to its logical conclusion, fighting "information war" yields a regime of public censorship that differs from China's only in flavor.
I used the phrase "disingenuous communication" not "disingenuous speech". The part that is misleading is a person using a bot that pretends to be another person (real or imaginary) to make a claim. The veracity of the claim doesn't really matter so much as the claims ability to stoke emotion. The part I find disingenuous (insincere) is pretending to be a human being and using other people's naïve assumption that the act is real to influence current events.

I don't because I'm not asking what is procedurally possible. I'm asking what is the evidence that right now, piles and piles of Americans support direct democracy. There are zillions of aspects of government that exist and that alone (or the fact that they haven't been reformed away) doesn't indicate widespread support or non-support of them. This is about as weak an indication as the historical arguments which tell you something about how some Americans felt at the time.
> how do you do it across languages?

You don't. Haskell doesn't do it for its C calls.

> And why shouldn't you be able do it?

You are able to do it, but it comes at the cost of restricting your languages to the design of the runtime. It ends up being a question of which you prefer. Different languages that can freely share code and data, or languages that are either very restricted or require a lot of (runtime) effort to share code and data.

> so it can't possibly be a single type

List<String> and List<Integer> may be two different types in Java, but they're the same type in Clojure. Erasing generic types helps you enjoy both the type safety of Java and the flexibility of Clojure, at the tiny cost of some unsafe-ish reflective operations, out of many that are unsafeish anyway.

> No matter how you slice it, it's an implementation restriction leaking out in a way that is inconsistent with the type system.

It's not a restriction because a JVM language could choose to reify its generics, at the cost of foregoing efficient interop. It just so happens that most JVM languages choose not to do it that way.
> The lithium is not recycled, due to economies of scale.

That's part of it, but even if we had very large battery recycling operations it probably still isn't really worth it. It's not hard to get 90%+ recovery but the amount of lithium in a battery is ~3% by weight. Spodumene, one of the important lithium ores, is up to 8% lithium.

> Same for the graphite.

Graphite is more of a technical thing, it's pretty difficult to extract it and it's pretty worn down. The physical structure is very important to performance and manufacturing is virtually all of the cost of creating graphite- so having the actual raw material isn't worth all that much.

More than graphite, I'd actually prefer to see the organic materials in a li ion battery dissolved off and then distilled. That isn't economical though.

> There is no foreseeable shortage of either graphite or lithium, with the scale that we use it, and the scale that it can be found in the wild.

With any scale we could use it, there's no way we would run out. If we mined as much lithium as we do lead, we would have enough to make every car electric with ~200 kWh batteries and no recycling. And as I said, lithium is more common than lead.

> Are there any concerns to the mining of either element? I've seen some scare posts, but don't know enough about them to know if they were worth taking seriously.

Graphite is mined in the same places coal is, but very roughly 5 orders of magnitude less. It can also be created completely synthetically from any organic matter, same way they make charcoal or carbon fiber.

Lithium as it is currently mined is one of the least environmentally impactful extractions. It uses up a lot of groundwater which is a problem in some places, but it's more about it not being replenished properly. There's no runoff like there is with heavy metals in Africa. There's pretty insignificant land use. The chemicals used in purification are super benign- things like lime or acid, in millionths or billionths of global use. Brine mining means you don't need to dump any rock anywhere, there's no hole, there's no significant dust or blasting- it's just a very large water well.
>"Since 2000 many new satellite measurements were done and the values improved."

The point is that "suddenly" people started measuring a higher baryon density to make it fit what was required for lambda-CDM model to fit the CMB measurements. Ie, the lambda-CDM model did not pre-dict the spectrum beforehand, they had to tune it to match the data.

Bourdain once described San Francisco as a two-fisted drinking town. Ain’t that the god damn truth.
Support for this stuff tends to ebb and flow - not surprisingly, depending on whether any particular party or force thinks it can gain advantage from it, or it thwarts its plans.

This can be seen especially well with the Supreme Court, which is arguably the single most undemocratic American institution. In the Progressive Era, SCOTUS was castigated by the left for slowing down the reforms, and eventually adopted the "judicial restraint" stance. Then the Civil Rights era came, with SCOTUS often the driving force - and now it was a good thing that it was forcing the hand of state legislatures regardless of popular support or lack thereof. Similarly, when you look at it from the right, the positions were essentially reversed - under FDR the right expected the courts to fight back against populism, in the Civil Rights era the right expected those same courts to defer to state legislatures.

More recently, in the 90s-10s period, it has been on full display - just take any op-ed with obvious partisan bias about any major Supreme Court decision. If the author agrees with it, they will usually exalt the wonders of an unelected body keeping the mob in check. If the author disagrees, then they will rant about how SCOTUS is undemocratic and thwarts the will of the people. Sometimes, the same author will write several op-eds over time, with varying position depending on the case.

> Shouldn't users have the best possible CSS engine?

Shouldn't they have the best possible COBOL compiler? The best possible VRML renderer? The best possible ICQ client?

Obviously CSS is way less dead than those, but there is always an opportunity cost. It's not a valid engineering argument to say "we should spend resources on X" without considering what else those resources could be spent on.

My initial comment is really just observing that maybe Microsoft's move actually does imply that they believe, no, the world doesn't need another CSS engine. I don't know if that's true or not, but I think it's interesting to ask the question.

We sort of a tacitly assume that the web will grow and grow forever and ever. But maybe that's just because we've only seen the first half of its life cycle. Maybe it is reaching a plateau and becoming a commodity. There are good questions about whether that's true and, if so, whether that's a good thing.

But I don't think it's illuminating to just assume the best way to improve the world is to have as many browser implementations as possible. Like an entire Dyson sphere populated solely by engineers each writing their own HTML parser.

Maybe the disruptive innovation has happened and the disruption was to move off the web. The Internet and HTTP is doing great. What mobile app isn't on the Internet? Maybe HTML+CSS+JS is no longer the optimal user interface language for it.

I guess I don't see what you're getting at. Browsers don't write themselves, so if you don't want to ask one of a couple of giant rich corporations to do something, that means you better have deep pockets yourself.

Even if Microsoft kept their web engine, how does that help? Now instead of asking Google, Mozilla, and WebKit for permission, you have to ask Microsoft, Google, Mozilla, and WebKit for permission and then get them to all agree on it.
