> Brand power can result in more sales, though, which usually does increase cash flow?

Yes, when you can get to the point where cash changes hand (this may be a very different moment from the "sale"). If cash shows up too late, then it doesn't matter how much demand there is, the game is over.

Endings from cashflow crunch can be very abrupt. A very dangerous time for many companies is under conditions of growth, because very often your outgoing cash happens now and your incoming cash comes later.

Tesla has to pay its employees each month, has to pay its suppliers on time (or lose them), pay its utility bills etc etc. The outgoing cash does not stop going out. But the bulk of the cash comes in only when they can hand a car over. And that's not happening very fast right now. The monthly outgoings per-car appear to be negative.
> I’ve always assumed Asian languages to be very informal as a lot of it has to do with context.

I'm not sure what you mean by this, but if you're thinking about "East Asian languages omitting 'necessary' grammatical parts all the time", then you might be talking about this:

https://en.wikipedia.org/wiki/Pro-drop_language

Note that this is a grammatical phenomenon exhibited by some languages (i.e., the characteristics of a language as a whole). Formality/informality is a concept associated with a particular "speech" inside a language, which is orthogonal to this. (You can say a particular speech in English is formal or informal, but it makes little sense to say that "English" as a whole is a formal or informal language.)

Popularity of Electron proves that they are not easier. Even Microsoft wrote VS Code in it.

I don't care much about Google but they did pretty good job with Flutter:

1. No special designer needed, you do everything in code. That means everyone can use their preferred editor.

2. Hot reload - you change something and it changes in the running app.

3. Headless testing - No need to own iOS/Android device to test iOS/Android UI.

4. Nice tooling - autocompletion, formatting, etc. Everything done via command line, with optional support for IDE.

5. Extensible - very easy to write your own widgets. There is nothing special about provided components.

6. Platform agnostic - "native look" of Qt/GTK is a lie, they still look off. To me it just triggers uncanny valley vibe. Not to mention that they implement native look from 5 years ago or more. And completely useless on mobiles. Flutter looks the same on every platform unless specified otherwise. Way less platform specific bugs.

The due process required by the 4th amendment is performed when the court issues a warrant, which they did here.

We can avoid AI investment boom and bust cycle only if:

It seems to me that when you interact with fewer people per day, you can put more time and energy into courtesy. There's also a higher chance you'll run into someone again, so there's more incentive to treat strangers well. And small towns tend to be less diverse, meaning there are fewer incidents of rudeness resulting from different cultural expectations.

Return to the gate (is one available? probably not) burning thousands of dollars of extra fuel, disrupting the gate schedule and inconveniencing perhaps thousands of other passengers to allow one person to disembark? Sounds unreasonable to me.

Also there is an upper bound on this sort of thing because crews have duty hour limits. They are not allowed to take off if they will be over the limit before they land, so there's only so much time they can spend waiting on the ground before they know they aren't leaving today, at least not with that crew.
I think you should try working at a smaller company. I've also been an engineer in Japan for a while and found startups a lot easier to deal with than mid-sized or larger companies. For example, you almost never have to send e-mails because everything is over Slack and surprisingly casual. Working with other teams is easy because there are only a small amount of engineers and everyone knows each other. Google Docs instead of Excel so you don't have to worry about SHIFT-JIS. Go somewhere without middle management where you work directly under the CTO or at most one other guy and you'll see less meetings. Of course, you'll still see some of the classic Japanese bureaucracy, but nothing compared to the bigger places.

My main gripe with Japanese companies is that they simply don't pay as well as American ones do.

Large open source projects are often created by, and receive the bulk of their contributions from, tech company offices where real-time face-to-face communication is happening behind the scenes. Just last week, a few people on my team in San Francisco working on something related to a Google open source project drove down to Mountian View for lunch to discuss it with the authors.

When you don’t have that luxury, it takes so much longer to get patches upstreamed precisely because the design controversies have to be hammered out in asynchronous text. Even then, it’s often down to a benevolent dictator for the project or the topic area to approve or deny, there’s nothing like the genuine collaboration of two employees in the same building working towards consensus.
I never understood this logic, population growth is 100% dependent on the amount of resources the system is able to produce, not the other way around. Resources are the precursor to growth. It is not possible to grow unabated then one day realize we're 50% short on resources. Population necessarily has to stabilize at around 100% resource utilization.

Electron is popular because web "developers" can't be arsed to learn anything other than JS. It's as simple as that. They live in the lie they tell themselves that JS development is easy, when it really isn't, tooling is disastrous, IDE is nonexistent, apps look bad, etc. They are just happy they manage to run something "desktop".

All those things you mentioned are true of Xamarin.

qt uses actual native controls, so not sure what is a "lie" about it; if something is not behaving correctly, it's a bug, and you open an issue. GTK does look bad and out of place, I agree with that, bug so does Electron. If it's between GTK and Electron, I'll take a proper GTK application.

> would have been the gold standard for years to come

I've written a lot of webforms and do really like it for "quick and dirty" UI's, but it has a lot of limitations that make it a bad choice for non-trivial apps.

Off the top of my head:
-styling
-resizing (text reflow and re-layout of items is very hard to get right/working)
-screen scaling (non-integer, say 150%)

I also found it requires a ton of boilerplate code to programmatically change the UI.

That said, my favourite part is the first class support for events. Knowing this paradigm made my shift to Qt (which has something similar called signals) much easier.

I don’t understand why people complain about Serverless vendor lock in.

Let’s split lock-in into two categories:

1. Essential complexity

DyanmoDB and Firebase are different products with different features and complexities. There is no “ANSI SQL” here. They are as different as they are similar. Moving from one to the other is a non-zero cost because they have different features your app would have to make up for or adopt.

2. Inessential complexity

Serverless functions don’t necessarily need different signatures and it is conceivable that a standard for HTTP evented functions could emerge. Many are working on this. I expect this to be largely resolved over the next few years.

Lastly, I’m grateful for ANSI SQL but over the last 20 years I think I’ve seen one or two clients migrate a mature Java app from one database vendor to another (excluding some very recent moves to AWS RDS). Keep in mind that JDBC is about as good an abstraction as we’ve ever had for database agnosticism.

When you choose to build a lot of complexity upon an abstraction you have to be honest with yourself: have you ever dealt with a service (storage, queues, naming, auth, etc...) that didn’t have leaky abstractions? Of those with few/zero leaky abstractions how often did you need to migrate to a different vendor? Why do we expect a rapidly evolving set of systems and services to behave like mature commodity software?

Fear of vendor lock-in is a premature optimization.
Yeah the airlines don't like to let passengers back off the plane because boarding the plane takes so long.

But rather than the fix the root of the problem of why boarding takes so long(because nobody wants to check bags any more because fees), their solution is to repeal regulations that let people off the plane in the event of an extreme delay.

Chronic delays actually have an impact on the economy as a whole in loss of productivity. But the greater good never seems to be of interest any more. And here the concern is only to the airlines bottom line.
I see what you mean. The symmetric part is noted. Thank you for the reply
... going from a BRZ to a Model 3 would give someone a little bit of bias.

All the things you described are very subjective. It's not "pure" it's barebones. It's not "distilled" it's optimized for cost savings in a way that would insult the average luxury car driver.

A mid-range luxury car these days often comes with a DCT or a very advanced non-DCT transmission that's capable of mind blowingly quick shifts and creamy smooth power delivery.

This is all coming from a guy who had a first month reservation for a Model 3 and went for a Volt instead after some hard thinking and a few... Tesla antics... I disagreed with, so it's not like I'm one of the people who thinks EVs "can't be enthusiast cars" like some people.

I feel like people are overstating what a change in drivetrains will do to car manufacturers. It's true this drivetrain adds requirements for space for batteries and infrastructure for charging, but car making will still be car making (ironically, as Tesla has shown with it's production issues).

My money is on Tesla becoming the next Porsche as far as volume and market. That's not a bad place to be, but it's not where the market has priced them at.

You're right, additional properties are desirable. The ACM has recently published a [set of guidelines](https://www.acm.org/binaries/content/assets/public-policy/20...) for algorithmic decision making. "Access" and "Auditability" are properties that mean it shouldn't be difficult to get the explanation, and that it shouldn't be possible to 'bullshit' an explanation afterwards.

The plane shouldn't be leaving the gate if it's not planned to depart in the next half hour. Shuffling passengers from "relative" comfort in a terminal vs. putting them in a hot box for hours without the ability to go to the restroom, is wrong. Arriving planes can deplane people, back away empty if they aren't leaving soon instead of filling up with their next cargo, allow other planes to arrive and deplane, and idle WITHOUT human beings for the sake of a little fuel cost savings.
The reactions to this information are quite interesting.

The evacuation 63,000 people is now known to have resulted in 2,202 deaths, cost $74 billion and still displaces 34,000 people seven years later. All for the benefit of a potential life expectancy extension a “few days” from avoidance of radiation and no known deaths prevented.

Yet somehow most people still think it was the right decision. This seems like some kind of congnitive blind spot.
> So it stands to reason that once they are good at making an affordable car, they’ll sell like hot cakes.

For me, this puts the cart very much before the horse. Once they're good?

Making an expensive car is much, much easier than making an affordable one. The fact that they previously struggled with making an expensive one could just as well be a sign that their process improvement and cost reduction skills just aren't good enough to play in the big leagues.

Their being at 15% of projected output sure doesn't conflict with that; if they learned a lot from S and X, I'd think they'd be doing much better.

The Bloomberg article isn't bad, but it's so generic that the discussion is generic as well (Tesla in general, short selling in general). That's the main trouble with articles that don't contain enough factual fiber.

Mostly what I'm aware of in the US is lead pipes from the water main in the street to the house. A fair amount of leaded solder in copper pipe joints, but lead pipes in the house is pretty uncommon.

As I would understand it, maintaining a neutral to alkaline pH in addition to the chlorine/chloramine used for disinfection of potable water generally produces a fairly durable passivization layer on lead which prevents significant lead exposure in drinking water. Responsible water utilities deliberately prevent the distribution of acidic water AND do some sort of at-the-tap water testing program as well. Needless to say, in Flint, Michigan, they screwed up at these things.

Even if our brains run on dark matter, or spooky quantum shenanigans, such explanations are still fundamentally materialistic, because they're still physical interactions that can be interrogated approximately the same way we interrogate how muscle fiber works or whatever.

As to social dynamics, well, that's like trying to explain the behavior of bulk matter or ensembles of things generally. The tools we use are quite different from explaining the behavior of atoms, but we're pretty sure that one way or another, the behavior of a rod of steel is determined more or less entirely by the fundamental particles/fields/stuff that make it up. There's nothing spooky about a bar of steel even though it behaves completely differently than the quarks and electrons it's made of.

After successive invasions, by the Mughals, Dutch, Portuguese and British it shot up to over 300 million, a much bigger rise say compared to other countries. Largely due to the poverty it was left in, people ended up having more kids to make sure they survived. Anyhow I agree it has been refused as the poverty levels are now being tackled and mass education programmes in place.

I should also point out that the sort of violence I'm talking about is things like wars, civil disorder, gangs, terrorism, failed states, anarchy, and other group forms of violence, not individual crimes like premeditated murder. The latter has a lot of conflating factors (a sibling comment mentions lead, and there's also abortion, better policing tactics, economic growth, etc), but to get a critical mass of people who are so disaffected by their current situation in life that they want to burn the whole society down, you usually need some form of major demographic or environmental change.
