LA has an order of magnitude more population than is required for functioning public transit. But you're right they don't have the density.

The key is to realize the cars themselves killed density.

Parking lots, parking spaces, and extra lanes all conspire to push humans and human spaces further apart. This then makes walking less feasible, cars more required, and more space required to accommodate those cars in a feedback loop.

Taller buildings are not required for density, far from it. Look at Somerville, MA, where just about nothing is higher than 3 stories, yet they fit almost 20,000 people into a square mile -- and they like it. What they don't fit is 20,000 parking spaces, and that makes all the difference.

Another point might be attribution. It's horrible when a driver is tired, drunk or simply misses something - but on a human level, you can understand what's going on. Also, you know the guy at fault and that he will be punished (at least, somewhat).

An autonomous vehicle, in comparison, is not relatable at all. Some equation delivered some wrong result, maybe it was something in the training set, so that's why the car suddenly drove into you. Bad luck. If you're lucky, you get some damage payments from the car company, if you happen to have enough money for a very good lawyer.

Sure, as a technical person, I understand some of the possible errors, but it still feels like a complex system that one cannot relate too with hardly understandable edge case behaviour. That's probably why we're so much more lenient with humans.

Nah. Mumbai has stock exchanges (BSE and NSE), banks and financial institutions, ports, the TV, music, and fashion industries. It's far more similar to NYC than New Delhi is.
Neither. I don't have a good answer for that problem. But I think it is safe to say that animals have a much stronger argument for sentience than brain organoids.
> The fundamental prerequisite for functional mass transit is a high population density.

What does "high" mean? I think this should be quantified, preferably by someone qualified.

Unqualified opinion: It seems to me that if we took all of the money spent on personal vehicles, time spent driving, fuel and emission costs, infrastructure maintenance, and costs to human happiness + safety, we would be able to provide a better transportation system.
Well, if it is as simple as you say, I agree. But I bet that "the structures that are responsible for suffering" is not clearly defined. And who is to say that these structures are not the very ones we need to be researching to find treatments for various mental illnesses?
This happens to be why economists tend to fear deflation far more than inflation.

Are you asking whether the 50% of people in Europe who died from the plague, and the survivors would have preferred to not have the plague?

This is exactly the issue I'm talking about. It's very plausible that the world got much better after the plague, and that the plague was an important catalyst. But it also seems obviously true that absolutely no one alive at the time would choose the plague in order to cause that improvement.
The fair comparison will show the same thing lol.

Each car in with the automated system will provide data to update all the other cars with automated systems.

I trust that process way more than individual unconnected human drivers. I don't trust Elon or Tesla corporation to care about human lives but I do trust that it will eventually get better and very quickly.

So, thank you for the altruism everyone, it will be fine.
I think Nix does a pretty good job at this. I've used it on Ubuntu, macOS and NixOS (with the latter two sharing the same system config, with OS-specific pieces tucked into if/else expressions).

I think of Nix more as a build system than a package manager (and in fact I've come to think of "package managers" as a sub-set of build systems, mostly used to work around deficiencies in Make which make it unsuitable for building whole operating systems via composition of their Makefiles).

One thing that Nix emphasises is that users should not be installing dependencies, like libraries; let alone in a globally visible, ambiguous location like '/usr/lib' (or /usr/bin, etc. if it's a tool that we're depending on). Dependencies are only needed 'ambiently' in a package's build environment; build products can embed references those by absolute path if they like, but they shouldn't be 'propagated' into the final system.

Interview with Yury Niño Roa on Chaos Engineering and SRE
The only job of a founder/CEO
I wrote big (10000x10000x10000) matrix multiplication and data processing (gigabytes of data) in the original comment, in which case the matrix size is small compared to the number of multiplications that the device has to make. Try n=10000 in your example (although I'm not sure about the differential solver part, as I don't run simulations), it's more interesting. Also differential expressions are more useful for simulation than data processing in my experience.

Of course CPU is faster for small matrices, but again, if I have hundreds of gigabytes of data that you want to process, CPU is always slower.
I highly suspect it is. I think even smallest part of our brain cells have their own consciousness otherwise our brain would not be so much plastic to adaptability.
Its just the point when we will prove it scientifically and decide what is the limit of our actions.
It's been stated elsewhere in this thread, but there really are a lot of practical, well-understood engineering issues with Elon's proposals that he refuses to admit or deal with. Here's a somewhat humorous review of his claims / what's wrong with them and how they stack up to actual civil engineering projects:

You're right that energy costs need to be accounted for when examining a potential capture method. But this is so blindingly obvious that of course the researchers are doing it. It is always accounted for when they are making their claims. As a single example see this recent article[1]:

> A simple chemical model estimated the rate of weathering for the crushed rock based on the local soil conditions. They also calculated energy requirements based on distance from likely rock sources, as well as accounting for the energy mix available to run everything. (The more fossil fuel burned to carry out the work, the less CO2 removed from the atmosphere in the final accounting.)

If it was true that any carbon capture method that uses energy will emit more carbon that it captures, then the researchers wouldn't have bothered doing the research. Yet they have, and do. Carbon capture is a very good avenue of research for mitigating climate change in the near term as we transition to new power sources.

you and rootusrootus have parsed this phrase incorrectly:

> more reliable than a human driver that's not drunk or sleep deprived

emphasis mine.
The fair comparison would obviously look at deaths per mile traveled for each category, not total deaths.
6 is also a total not a rate per year like 38,000. The rate of self driving car deaths is roughly identical to the rate of non self driving car deaths. However, unlike drivers these systems can significantly improve over time.
> Temperature ranges aren't as wide.

I thought people were mounting these out in the garage.

For me that would be an 80° delta between the highest summer highs and the lowest winter low. The delta in places like Wyoming would be a lot more.
Do they still have the oscillation problem? Where they start to pitch and the pilot over-compensates which results in an uncontrollable pendulum swing until it stalls? I recall that killed quite a few early pilots.
They don't know who he is. American adults are uninformed about most issues and will just parrot what they're told to believe in. Mass media paints him as a bad person so that's his public image.
Interesting. This sounds like its related to triggering "system 2" as Kahneman would call it in "Thinking, Fast and Slow"

Experimenters recruited 40 Princeton students to take the
CRT [Shane Frederick's Cognitive Reflection Test]. Half
of them saw the puzzles in a small font in washed-out
gray print. The puzzles were legible, but the font
induced cognitive strain. The results tell a clear story:
90% of the students who saw the CRT in normal font made
at least one mistake in the test, but the proportion
dropped to 35% when the font was barely legible. You read
this correctly: performance was better with the bad font.
Cognitive strain, whatever its source, mobilizes System 2
[slow, conscious, laborious thinking], which is more
likely to reject the intuitive answer suggested by System
1 [the immediate, unreflective thinking by which we make
most of our minute-to-minute judgments].[1]

Bizarre Design Choices in Zoom's End-to-End Encryption
tldr: The php process hit the max connections inside the database pool, which caused blocking within the php threads, which caused a thundering herd problem, and without correct tracing inside the wordpress php files the authors didn't know this and assumed that there wasn't enough caching on the front-end.

"at least 2 database-touching requests for every person reading the post" should never be a blocker for 2 requests per second unless you truly do not understand your application infrastructure at all.

on edit: The better solution here would be to figure out where the MySQL server was being put under load -- hint, it probably was 99% idle, because unless that sidebar file was making an unindexed query there's no way things would take 500ms -- and then realize that you need to bump up the number of database connections in your php pool to be MYSQL_MAX_CONNECTIONS so that php isn't blocked on obtaining a new connection. Problem solved.

Hi! Ryan from the Climate team at Stripe. Yes, the field is super young. Regardless of previous attempts, the world is very likely going to need giagatons of carbon removal, and the necessary technologies won't magically scale without the support of early purchasers. We're taking a portfolio approach and will be expanding the number of projects we support over the coming years. Regarding "indulgences", this is no substitute for emissions reduction, and we aren't purchasing traditional offsets or suggesting this as a mechanism for carbon neutrality. More details on all this in our FAQs if you're curious! https://stripe.com/docs/climate/faqs
No, you should try to have privacy at all times. Otherwise those who really need it will be in the minority and easily hacked.

Image Stacking Reduces Noise and Recovers Signal
I think learning Rust first - and then possibly C - is a better plan for your background of python and matlab. I think it can be difficult to appreciate C when coming from the higher-level languages, and so while it may be easy to get along with it, it won't really change how you think about code... My opinion would be different if you had done no programming before, then I'd say start with C, then Rust.
You would still need to use mocking to test the imperative shell
I have a complete unlovely thought; web browser needs a rewrite with thin web specs (imagine javascript the good part book meme). People think it's impossible to rewrite, but I believe it's only because it's a mess. Inventing a new programming language and new DOM api that works greatly with webassembly probably worth it, consider that the next 10 years the web is still not going anywhere. You may laugh at Flash .. but hey do you love "hydration" thing? I'd love to have an isomorphic?(terrible name) template engine that rendered as text as well as client program binary. Do you love OS based form control that can't be styled? I'd love a complete separate controls from OS, clean the contract between widget and actual system api. Just stop caring (coercing) how it looks, just provide api to enforce how its functionality works, we already have these bunch of aria- thing.

The question is what block the progress of making it complete, what kind of problem? I believe it's not a technical problem. Maybe incentive?
The Christian idea of an afterlife that I was raised with and apparently most people in the US follow is an eternal afterlife and there is no opting out of it once you get there.

Another interesting systems programming language is the Pascal descendant Oberon which is (way) simpler than all three languages mentioned:

Nature already has powerful carbon-removing technology, it's called a tree. Why reinvent the wheel? Simply fund reforestation efforts. Plus many wildlife species will be saved from extinction. For example, orangutans in forests of Borneo island.

EDIT And besides, humans will survive climate change, we are 7.8 billion. But we made 1000s of species go extinct. So I say carbon capture is the wrong problem to solve.
Typora's markdown experience is great. I wish to see the same in VSCode. It isn't feasible to use Typora just for markdown and VSCode for other type of files.
I see those as three options: C, C++, and Rust.

I'd suggest learning C. It's the simplest language of the three, and it's the lingua franca of systems programming. You will have tons of resources and examples to work from. And you won't get stuck/frustrated over type system or lifetime issues. You'll always be making progress with C even if it's buggy.

While learning C, I highly recommend that you dabble in Rust. Rust has introduced important concepts to programming that will not go away, and just does a lot of things really well, including C integration. You also might appreciate the really easy cross compilation system for embedded development.
In many ways it is still ahead of its time today. All electrical signals coming from user input devices are causing interrupts in the CPU resulting in a jmp directly into the interrupt routine which gives you the unmatched I/O latency and responsiveness. In a world of USB polling, CPU sleep/wakeup, compositing desktops and slow switching LCD-Displays it is easy to see why people enjoy going back to the Amiga for good old times because some things really were better.

Whenever I do a SEO workshop I ask 3 questions to my audience:

* How often did you Google this week?
* What was the last thing before the last thing that you Googled?

For the first question, I get laughs. For the second one blank stares.

Later, I shoot another question:

* What is the last thing you read, that you googled before, top to bottom?

For the last question everybody looks at their feet.

The use case I optimize websites for is:

* Users do not know when they Google.
* Users do not know what they Google.
* Google is an extension of their thinking.
* They do not read what they find.
* It just need to move them forward in a way.

We are all users.
The fact that you've edited your comment to reference number of vehicles sold and miles traveled shows that you don't need any help coming up with an alternative comparison that is more reasonable. You already know that the numbers you initially cited need to be divided by their share of miles driven.
I had all the Google tools I use in my bookmark toolbar without any titles, and the previous icons made it easy to distinguish them. Now it's just a mess and I'm back to adding a title to each of them, losing space when a single icon worked.
That gets into fun with statistics.

On a pure deaths per mile basis Autopilot is already safer than the average car driven by the average driver. However, people downplay that by adjusting for various things making them relatively equivalent with not enough data to really say one way or another.

Basically, there is simply not enough data to be statistically significant improvement or detriment vs
drivers, but there is enough data to say they are safe enough to be used.

Building on from that, a lot of large organisations have no progression for developers that isn't up the management ladder. I got sucked into this - realising I wanted more money, so got promoted into the management track (as that was the only route), and hated it. I soon quit the org and went freelance, where I could close the salary gap, yet still remain hands on technical.

The difference is that the volunteer would be someone walking around with them all the time, so if POTUS wants it or not, they would eventually get to know each other at least a bit, which makes a killing decision more personal (even if not executed by POTUS themselves).

The term has a broader meaning than you make it seem. According to the link you posted yourself, cultural appropriation appears “[when] cultural elements are copied from a minority culture by members of a dominant culture [and] these elements are used outside of their original cultural context”.

In most cases, those appropriating other cultures actually love whatever they appropriate. That’s why they copied it in the first place. A lot of the flack for cultural appropriation comes not from that it ridicules other cultures, but rather that the artists/entrepreneurs/etc with visibility tend to be those from the dominant culture. They can profit from the ‘cool’ factor of appropriating other cultures, whereas for those from minorities that are being appropriated it is hard to find a spotlight.

Of course the kind of cultural appropriation that you describe also exists, i.e. wearing a native american headdress to a party or something like this. But that would be a subset and is not the generally used definition.
To be clear, initially HTML was defined by the W3C. Then when they tried to replace HTML with XML and the browser vendors revolted, the W3C essentially lost control over this.

Basically the W3C over-played it's hand. It thought by re-writing standards from HTML to XML it could force Apple/Opera/Mozilla to re-write. In the end, the browser vendors got together and created a new body that would be responsible for HTML. They've skirmished for control, but there's no question WHATWG and browser vendors are in ascendency. From 2007-2019 they both had competing standards of HTML, but since the browser vendors were on WHATWG they would just implement their own version making it the de-facto standard. So, in 2019 W3C announced they'd just use the WHATWG HTML.[0]

I expect if the W3C pushes anything the vendors consider too arduous (eg a re-write of CSS into constraints), then WHATWG would create a CSS working group and the process would repeat.

This reminds me a lot of the power of the Supreme Court, specifically President Johnson's quote about it when they made a ruling he didn't like. "[The Chief Justice on the court] has made his decision; now let him enforce it"[1] The stakeholders of WHATWG have an army (of browser coders), whereas W3C needs to rule by consent of the ruled like the Supreme Court does.

Absolutely, but I really doubt that Apple will just shrug its shoulders about the lost profits and throw in an ad-free search engine for the price an iPhone.

My prediction is that they will try to monetise this somehow. And the most likely way to do this is via some privacy friendly advertising model (or an ad/subscription hybrid). They're already doing it with Apple News.
Click tracking is MUCH more significant than ML/AI, Google results were very good even 10 years back when they were just based on click tracking. Whatever they are doing to parse/steal other websites data to show as snippets is only complicated because there is no schema. Look what Amazon did, they made people implement "skill" so it's all API now.

All that was solved for majority of use cases and leaped ahead by Amazon in under 5 years with Alexa, deployed as tiny hardware.

Remove click tracking and top 1000 sites from Google and it will be shit, no amount of ML/AI dance will solve that. Apple can just do top 1000 sites from each country with click tracking (to track which result users are preferring) and significantly cut traffic sent to Google. They already try to do this with Siri.

Bing was chicken(user) and egg problem (click tracking to optimize results).
