I didn't say that I had shorted them yet, simply that I see no hope for Uber (or Lyft for that matter). Of course with the recent inversion of the yield curve, I'm pretty bearish on the whole market and likely to get out for a year or two as I did in 2007/8/9.

If you define vocabulary to include not just the words, but the appropriate usage-in-context, then sure. Arguably that's not a short formal list of rules you memorize, but an intuitive understanding of thousands of specific cases that can only be acquired through massive exposure to the language.

I'm not sure what the word for that is, it's neither vocabulary nor grammar, and yet more important than either of them -- actually even more important than both vocabulary and grammar put together (lists of words and lists of rules).
This ("free markets are an illusion") is reductionist language that makes it difficult to communicate and understand one another. Your use of "extort" is another example of language abuse. It is hyperbolic language that serves only to distort understanding.

> much more space is wasted on column (field) alignment in records

Hmmm... I don't think there is much alignment going on within the data pages. Efficiently packing data is a matter of avoiding excessive I/O and I can't imagine databases were not carefully optimized in that regard, especially at the time most of them were invented (with less than a hundred I/O operations per second on that hardware).

Plus the DBMS is free to rearrange the physical order of fields as it sees fit (e.g. MS SQL Server coalesces boolean fields into a bitmap).

But I'm not an expert on physical row structure, so I might be pulling this out of my backside. :)

> Frankly I'd sooner worry about PK index size here;

Yes. And how many indexes are there.

> if typical BTree index size is strictly proportional to field size

Also the fill factor (i.e. how much free space is left in the B-Tree nodes after splitting). Sequential values can have a big advantage here due to 90/10 optimization I mentioned earlier.

BTW, some DBMSes can encode integers in variable format, so the actual values matter, not just the nominal "column width". The same is of course true for varchar, but also for char (typically). The char(n) is just a logical concept, it doesn't require n characters of storage unless the value is actually n characters wide (unless you are still working in Clipper ;) ).

> or if it's optimized away to any extent, perhaps via prefix coding

Prefix compression is supported in some DBMSes but not others (e.g. Oracle does it via CREATE INDEX ... COMPRESS).
Here's a site (with terrible UX...) from comparing liters/kg for various foods, broken down into green/blue/grey:

https://waterfootprint.org/en/resources/interactive-tools/pr...

Beef lists there also at 15,415 liters/kg, with a 4% 'blue' (filtered/treated) component, which works out to 616.6 liters/kg - still double the total water kg/liter for the avocados (which, themselves, will have a green/blue/grey breakdown).

(It's also not obvious to me that one should consider 'green' water as a completely free resource. Plants bred for fast growth with constant replacement will consume more water, which in turn won't find its way into aquifers.)

I suspect most of the hate vegans get are from other "more pure" vegans. Purity is how vegan cult members judge each other. Not how normal minded people judge vegans.

As for "some good", you might really want to get off your high horse and objectively look into the catastrophic environmental damage that a vegan diet causes. Not to mention the long term harm it does to the human body.

You literally cannot survive in nature on a vegan diet. You'd starve to death. You literally cannot have a vegan diet without fossil fuel ( good luck growing avocados in alaska or NY ). You literally cannot have a vegan diet without killing nearly infinite number of bugs, worms, vermin, etc. I know truth can be triggering to a cult member, but this is agricultural and economic reality of a vegan diet.

Personally, I'd love to society move to a "hunter gatherer diet" as that's the most natural, healthy and environmentally friendly diet possible. Rather the elites want to put us on a diet akin to the "vegan diet" livestock on industrial farms are fed. It's funny how industrialization is turning humans more and more into livestock. Maybe the UN will recommend troughs filled with vegetables for human beings.
Well, sure, maybe.

It would just be nice if the article backed up the headline rather than leaving us to speculate.

This is more the truth IMO. They aren't consciously being jerks because they don't have time to have those kinds of thoughts. Which means that throwing criminal charges around months later won't help anything. The only way to change such behavior would be for people to practice serious everything's-on-fire drop-everything-and-run-NOW evacuations regularly. I'm not going to hold my breath waiting for that to happen.

Okay, maybe having a short preflight safety briefing that people would actually pay attention to and that told people that would help. Or maybe just scare the crap out of everyone.
"you wouldn’t expect your supermarket to randomly sample all their product."

Netherland is similar. Online payment is supported not through the card itself, but by the banks through a system called iDeal, which performs a bank transfer connected to a purchase in a webshop similar to how a PayPal transaction would work, except it doesn't rely on a credit card number, but on a through two-factor authorisation process between you and the bank.

The 2FA used to be done with one-time TAN numbers on paper, but many banks switched to a special device that generates these numbers on the fly based on your account, the amount transferred and some random number, and in recent years many banks are switching to a mobile app for dedication. But authorisation always happens through some form of 2FA between you and the bank, and never relies on sending any kind of sensitive information (like credit card numbers) to third parties (merchant, PayPal, whatever).

Sadly, iDeal is only supported by Dutch banks and Dutch merchants (and international merchants that care about the Dutch market, like Steam). I really wish there was something like this that was internationally supported. Relying on sharing credit card numbers, seems really backwards and terribly insecure. Well, it is terribly insecure, as evidenced by all the panic when a company leaks a million credit card numbers. You never get that kind of panic when someone leaks a million account numbers, because in a secure system, that's simply not enough to get any money out of that account.
At most I have anecdotal evidence of my work with such people.

As well, if you want to be wealthy that badly you’re better off leaving journalism and doing something else.

I think this rabid kind of speculation is unhealthy. You’re basing your rational on further assumptions.

At the core you seem to assume everyone is so vulnerable that such a situation is more than just plausible, but the most likely reality.

I disagree. So I guess it just boils down to philosophical differences.

For what it’s worth, again, my work has shown me the greatest extent of coordinated government/powers “interference” has been the request for XML copies of published articles. The greatest extent of corporate/financial powers interference has been to cut the legs out from under journalists to maintain margins.

I have no evidence those journalists were coerced into the actions they took outside of the effect of a social media echo chamber. They’re not the only ones.

Add that together and I feel I can make the assumption there is no grand conspiracy otherwise I likely would have seen some traces by now.

This isn’t directly related, but I see far worse coming from corporate executive business management. And they don’t give a damn about the stories.

And you know, I led off with “the press is not perfect”. But it is supposed to be free. Freedom often comes with the tag line that you have take the crunch with the smooth and work through problems.

But coordinated grand conspiracies—no.

WhatsApp famously built a company with a billion users, sold for $19 billion, with about 50 engineers, with a product built in Erlang. I think that's the best example of what you're asking about. It's not clear they could have accomplished the same success with any other language.
> Is it really too much to check the bags in and wait at the baggage carousel at the other end to retrieve them?

Yes. For me, that's really too much, if there's an alternative that's much quicker to check in (online), must quicker at arrival, doesn't have the risk of losing your luggage, and (in today's world) much cheaper as well.

We make it a point in our family to be able to do all our travel with carry-ons only, even if it's a multi-week trip to the other side of the world.

The last 2 times we checked in our luggage, part of the luggage did not arrive. If you have a carefully orchestrated vacation going from one place to the next, that can be a huge hassle.

This is a little hyperbolic though, because git does have UI above the reflog designed for catching the most common mistakes. The reflog is a powertool, it is not the default UI, and most people never need to look at the reflog.

git rebase has an "abort" feature when you need to redo it. git has tag & branch & stash features if you want to save what you're doing before you rebase. The problem with keeping and showing rebased branches are that 1- you don't need them after the rebase is successful. You only need them when the rebase is going badly, and 2- you'd have a lot of unnecessary noise pile up. I often rebase multiple times before every push. I don't want to see them all, you probably don't either.

That said, I fully agree that git's UI could be better and help beginners feel less fear!

It's not pointless at all. It makes the Web platform more complicated to implement, which, as the company that owns the leading browser, is in Google's interest. The more complicated the platform becomes, the harder and more expensive it will be for any potential competitors to ship a product that can challenge Chrome.
This misses the actual advantages that a managed service provides, like the fact you don't have to worry about the stuff you mentioned. Does your solution scale to multiple cameras?

I'm not saying your solution is bad, my house has the same thing (with 4 cameras around the house), but most people don't want to spend time managing yet more stuff, and debugging their camera system if something goes wrong.

There is no easy way.

I agree with you that newer interfaces (Windows 10 in particular) are mostly not very good. But I wouldn't say personally that KDE is a good example of 2000s era design. I think Gnome 2 was the absolute pinnacle of PC GUI design, actually. Having instantaneous access to Applications / Places / System (with text labels!) makes so much sense; it's one of the few desktop environments that pretty much any competent computer user could sit down at and immediately use.

Actually, I have my KDE set up to be an approximation of Gnome 2 with a few tweaks that work better for me, but I'm not under any impression that it approaches the immediate usability of Gnome 2.

I recently got 1.5Gbit fiber in Toronto (it was only $10 more than gigabit, and that was only ~$20 more than 250Mbit...)

Anyway, it hasn't been hugely transformative, but it alleviates a few headaches:

1) The biggest benefit is that uploads/downloads are symmetric. If you backup to the cloud, this is a big deal. All of the "definitely overnight" stuff can now be done in under an hour anytime.

2) I never worry about what anyone else in the house is doing. Stream all you want over wifi, there'll still be a full gigabit of bandwidth for my workstation. I don't have to mess with QoS or anything; there's literally just an oversupply of bandwidth. In fact, until I upgrade to 2.5 or 5gbit ethernet I literally can't saturate my connection...

3) I'm less likely to hoard stuff. I don't bother downloading steam games in advance and keeping them installed forever; I just download on demand and delete it after I'm done with it. This is currently allowing me to transition everything to SSDs.
OR how about the super questionable culture of the company and its executives and leadership? Those are such red flags by themselves... This is a horrid company with a horrible past that wouldn't die because of VC money.
> The 27MM is on top of the 33MM, not out of them.

This is wrong. Not sure where you came up with this. I think you are confused because Matt talks about the shorts creating more shares..

There aren't really 60M shares, read the last paragraph you quoted to figure out why.
Citations, not personal attacks.

For example, as to the claim it is the safest production car ever made, you could cite NHTSA finding the Tesla Model 3 had the best combined VSS (Vehicle Safety Score) ever tested. [1]

Regarding remote maintenance, the latest firmware does add the capability to notify the operator of an issue and pre-orders parts to your home service center. [2]

I can't speak to drive train specifically, although Tesla has stated they design and build to a 1,000,000 mile standard. Longevity and low maintenance cost is a huge factor for Tesla buyers. A Model S driven for Tesloop logged over 400,000 miles and ended up with just a $0.05/mile maintenance cost. [3]

Battery reliability is much higher than everyone expected, and owner surveys of older Model S batteries show 90%+ capacity after 160,000 miles. [4]

Efficiency is easy to demonstrate that Tesla is way ahead of the pack. In my Tesla Model 3 AWD with 19" rims I get ~220Wh/mile, and the RWD version with 18" rims is more efficient than that. The only more efficient EV I know of is the Ionic, which has a 28kWh battery and 3,100 lbs curb weight allows it to beat the Tesla Model 3 at 50kWh battery and 3,552 lbs by 4% in terms of mpge, but has 100 miles less range.

The Tesla Supercharger network is one of a kind. The V3 Supercharger update brings the fastest production charging in the world.

The software ecosystem, presumably meaning OTA updates, have brought innumerable software features, and even hardware performance upgrades (braking and acceleration) in the last several months. My son also really appreciates the new Atari games that keep coming out.

You can debate whether you think AutoPilot is the best driver assistance package available, but it is far from "blatantly false". AutoPilot takes me to work and back every day with very little manual input. It makes a heavy traffic commute totally stress free. I do look out the window while I have it engaged though, not watching a movie on my phone or tablet.

>I've always thought applied math has a leg up on abstract math because of the connections to real-world ideas.

I don't particularly like this dichotomy. Abstract math is connected to the real world because if it wasn't it wouldn't exist. Overall people who say this stuff are just referring to math that is only derived to work from an experimental standpoint and not from an axiomatic standpoint.

Machine learning is one example of a mathematical field with no axiomatic basis and the the pythagorean theorem is an example of one that is derived from the axioms of euclid. Both exist in the real world and are therefore applicable.
