Given the central place of energy in the economy, I don’t think taxes would work: they would merely increase prices provide incentives to develop technologies leading to more Javon’s paradox, as you said. The only solution I see is banning extraction. But banning something? Unthinkable!

I do not understand the attachment to the slogan "Defund the Police". If a slogan requires a much longer explanation essentially explaining "what we really mean is", then it isn't a good slogan. Especially considering there are better word choices such as "Demilitarize the Police".

Ultimately, 'defund' - to most people - doesn't mean reform. Insisting that the vernacular is incorrect is just fighting an uphill battle.

It very much matters when a Judge who is politically appointed as they are in the US has to decide if you're right or wrong. Then what is better for the economy and for corporations will win out.
I think it’s worth noting that mileage doesn’t necessarily correspond to maintenance expenses. It’s only a rough rule of thumb.

People like to talk about mileage because it’s an easy-to-measure stand in for the age of a car based on its usage. But over time they forget that like in humans, there’s a lot of variation at the same age.

There’s other factors like road conditions, cost of parts, cost of labor in different parts of the country, unexpected events like fender benders, etc. that the mileage number doesn’t capture.

The same 100k mile car driven in a leafy suburb where not much goes on is going to be different from a car with the same mileage driven under harsher conditions.

Is nobody going to mention what a pain in the ass it would be to change all those filters regularly? I love in a somewhat dry and dusty area and need to change my filters (near the ground) every two to three months. I'd hate to have to climb up a ladder to change eight to nine filters that often.

It's typical only where there is a huge macroeconomic shock like in 2001 or 2009, or because those large companies were either horribly managed (i.e. outdated business model). None of that is true right now with respect to Tesla...huge increased in oil prices recently should actually make EV's "cheaper" in comparison.
Yeah, and they can be stupid expensive for small side projects with a handful of contributors. If you want a Netlify site with a background function that serves 10 visitors a day with 3 people occasionally logging in or pushing code, you pay $57/mo to execute $0.0001 worth of Lambda functions. Maybe it's worth it if things take off, but before then you're paying a lot for very little. So, you host on a DigitalOcean droplet or directly on AWS, and bear a migration cost if you were to choose Netlify as soon as things start growing.

That's where this "take" comes from. The fact that the founder is Ukrainian, and instead of addressing the immense geopolitical complexities of the turmoil in which he & his countrymen find themselves, they exploit the pain to give benefit and PR to their technology startup.

Either the situation in Ukraine is not quite as dire as the post suggests, or the founder is insane. Either way, he's a liar and a manipulative person who has their priorities backwards.

Actual wars do not allow for venture capital based software firms to take hold.

I was assuming it was just movie posters and screenshots from online articles/reviews/imdb etc, and not any analysis of the video itself (I might be wrong though - using video would make the number of available input frames grow by orders of magnitude, not that there is a lack of pictures online).

E.g. The Shining picture of Jack Nicholson with the door isn't representative of the "look" of the film, but very much an iconic still frame and basically what you see in a Google image search for "The Shining".
That's an excellent question plaqueing economists and workforce development professionals. It made send for people to stay home when they were receiving supplemental federal unemployment insurance. But now? How are they surviving?

I think that workers at this level (blue-collar, light industrial, low-skilled, whatever) have become empowered within the economic turmoil. I think that whereas before, they'd take any job at any wage out of desperation, now they recognize there's much more demand for their services, so they can jump around, seeking for the better option. I suspect that it'll all normalize over time, but that's the one commodity we can't afford, at this point.

>My understanding is that the correlation is very strong.

Look at the table that I shared. A very strong correlation would look like:

Bottom 20% > bottom 20% = 100%

Next 20% > Next 20% = 100%

....

Top 20% > top 20% = 100%

Pure randomness, (e.g no class impact whatsoever) would look like:

Bottom 20% > bottom 20% = 20%

Next 20% > Next 20% = 20%

....

Top 20% > top 20% = 20%

What we see is far closer to the latter than the former. Another way to put this is every single group in America is more likely to end up in a different economic quintile than the one they were born in!

>In the USA today, a child in the bottom 20% of the income distribution only has a 7% chance to ever reach the top 20% of the income distribution.

What do you think that 7% would be in an ideal world? 7% sounds small, but keep in mind that in a system where birth class had no impact whatsoever, 7% would become 3x higher to 20%. Also, keep in mind that this is the absolute worst case for all of USA and a tiny part of the big picture. E.g. the most capable 20% of the bottom 20% don't make it all the way to where they would under a fair system 60% of the time (this is about 2% of the population). Most people (numerically) have very little impact from class.

>From a purely selfish perspective, if tomorrow's Einstein is born poor in america today, its very unlikely they will ever be able to make use of their talent to aid the world.

This is hyperbolic. If they were born in the bottom 20%, and not part of the majority that bottom 20% that escape poverty, maybe. Keep in mind that the real Einstein was born into the 1% in Germany, son of a factory owner, not a chimney sweep.

>Poor people stay uneducated and poor.

This is objectively not true. Most people born in the bottom quintile escape the bottom quintile, as demonstrated by the data.

I agree that more should be done to help those borne into poverty, but this fatalistic attitude does not match reality. There are some noteworthy effects of birth class, primarily in the most extreme situations, but most Americans are unaffected. For those borne into poverty, we know what factors generally increase mobility. If you stay in school, off of drugs, and keep a clean criminal record, chances are very likely you will escape the bottom quintile. I think more effort should go into helping people do these simple things, and less effort should be spent spreading the idea that outcomes are determined by birth.
I would qualify this by saying the priors matter. Twitter has torched their credibility in a flaming dumpster fire. That changes how one might make assumptions.

I live near a rapid bus line in Seattle. One stop is a block away from my house, and the other stop is 2 blocks from the office.

The traffic to the office is always awful, so a pleasant ride to the office, skipping traffic via dedicated bus lanes on the route, without needing to drive, sounds great to me in principle. I WANT to like this. I WANT to use this. But, there are several problems with it in practice.

For me, the bus is still significantly slower than driving because of all of the stops, even though it skips car traffic. For my wife, who needs to walk 10 blocks from the bus stop to her office, it's even slower.

My wife and I both get motion sick, especially if I don't get a forward facing seat.

Other people riding the bus smoke drugs, don't clean themselves & smell awful, scream loudly & incoherently, etc.

On the 10 block walk from the stop to her office, my wife saw homeless folks fighting, some screaming, and other smoking fentanyl. As a small woman, she did not feel safe, and informed me she wouldn't be taking the bus again. With our car, she can drive directly to the secured parking garage in her office, no safety risk.

We're going to stick to the safety, security, and speed of the car, thanks. It's not the lack of infrastructure, public transit is just a much worse experience.

None of this will get better, our transit agency doesn't even have the guts to reduce fare evasion via real enforcement because of the wacky political climate here.

https://www.king5.com/article/news/local/sound-transit-fare-...

Find a way to make public transit clean & safe and we'd probably ignore the other negatives listed above. Unfortunately, the political climate in the US in areas with adequate public transit makes that impossible.
Windows 11 wsl2 is supposed to be able to run gui apps (without needing hacks). It should therefore be feasible to run vscodium on wsl2 itself and develop that way. I used wsl2 for a bit and it was really nice but it had the side effect or reminding me how much I missed running Linux and how much I didn't want to upgrade to Windows 11.
People hate dealers, love getting a car today. Dealers do what they do because it works, and it is largely what the consumer seems to prefer. You don't think dealers would do online fixed-price sales for pre-orders if it worked? They would! And they will, if the market rewards that.

Very few people actually want to wait weeks or months for the car. HN doesn't believe that, because we're tilted towards Tesla fans who are inclined to be okay with this. Average Joe will put up with a few hours at the dealer to get their new ride today.
> C++20 is not the same language as C++11, which was not the same language as C++03

This is not a good thing. In fact, it's a shockingly bad thing. C++ is basically 40 years old, and still every few years the C++ community feels like, "OK, now we know how to get C++ right; yeah the old C++ was a mess, but now we just need to add these 12 new features and it'll all be good."

Unfortunately many of the problems with C++ are due to mistakes in its early design. It was wrong from the beginning.

I've been programming Rust for 6 years. C++ for over 20. I'll take Rust every day of the week and twice on Sunday.

I don't know. Maybe if you were concerned about this, the solution isn't to sell your company that depends on access to one company, to their direct and biggest competitor. Hammerhead bears responsibility for not doing things that have their customer's interests at heart.
I understand that I'm advocating for the devil here but think about the semantics for a minute:

Big evil corp says something that's false for marketing. Nobody believes it. This is the most common by far, how often do you hear advertising that's way overblown? Probably trillions are sunk into this globally every year.

Alternatively, big evil corp might actually say something true and it's still in their favor so they spend money on spreading the word here, too.

People use this argument "it came from an evil corp" (usually phrased as propaganda, signaling you must be stupid to even listen) as a shortcut for "it must be false". I don't know whether it is in this case: we need to weigh it critically. Is it not possible that this corp saw an advantage and used it, regardless of whether the argument was true?

It seems like a shortcut that's easy to subscribe to and be able to move on with your day because you're not too blame. Maybe true, maybe not. I'm not sure, but this is not the way to find out.

Seems like several others, my actual development career began on WebOS. In high school, I was intrigued by the idea of a web-based, multitasking capable smartphone and begged my parents to buy me one.

Ultimately I learned a ton and have great stories such as staying up all night re-architecting Weatherman (https://appcatalog.webosarchive.com/showMuseumDetails.php?&a...) because of the popularity (and this was before it was on the WebOS store, at this time it was invite-only so I had to post it on a forum!). Weatherman was just a hack on top of a hack on top of a hack. There was no Canvas API on the device so I had to generate the weather images on a server and then send them to the device, for example.

The highlight for me was winning one of the top spots in the Palm Hot Apps competition for the "free apps" category with Pixi Dust (https://appcatalog.webosarchive.com/showMuseumDetails.php?ca...). The physics weren't accurate by any means, but it was the first time I had seriously used C++ (I think it was, it was so long ago!).

I miss having platforms like these with innovative ideas and small communities. I learned so much by having to hack my way around the limitations of the operating system, and really miss WebOS overall. I think I might still have an old Palm Pre sitting a drawer somewhere.

> At this point wouldn't it be better to just use a regular GC language?

No, because you wouldn't slap `Arc` on every single variable. The example from the blog post is a dispatcher and `Arc` is then needed for dispatched functions. The same might be true for queues and other stuff where you need to move stuff between threads, but other than that it would be mostly `Arc` free.

As an example: when you write a web service in one of the frameworks like Actix, you typically use `Arc` for stuff that you need to share between all of the handlers like DB connections, queues, counters etc. All of the other stuff would be relatively straightforward Rust without much consideration for lifetimes.

> mature, professionally managed companies

But Tesla is supposed to manufacture more cars than it manufactures now. It is supposed to grow its capacity to explain its valuation, at least partially. I think they make 1 million cars per year and want to make as much as Toyota + Volkswagen combined who make probably around 20 million cars per year.

So how some short term cuts by 10% connect to the idea that Tesla will grow by 1000%?

Of course in every company you can trim some fat, but isnt Tesla supposed to expand to at least partially explain the valuation?

Also if they wash out people who can get a better job, they are left with those who are stuck there (there is a difference between firing non performers and making best people leave - I define best as someone who can find another job). Will their quality stay the same? Their competitive edge was markering and (supposedly) better technolofy / engineering / programming. Losing top staff in exchange for engineers who accept working as in a sweatshop doesnt sound mature for me.

Yesterday I read some part of a report made for a national company about their carbon footprint. They got an auditing firm to produce nice charts. Then they hired a communication agency to present the result to their employees. They literally wrote: “Don’t show this chart, we don’t want employees to lose motivation.” What the graph shows is that the main source of emissions for this company is their investments.
Its a completely crazy process but it works roughly like this:
(going from RDS Postgres on 12.6 to Aurora Serverless V2)

1. You create a snapshot of your original db

2. You update that snapshot to 13.4 (NOT 13.6!!)

3. You have to use the AWS CLI (because the online migrate doesn't work) to create a cluster from the snapshot

4. Remember this cluster is 13.4, serverless only works with 13.6, so we have to upgrade it later again

5. However we can only upgrade it when there is a running system

6. so we create a non-serverless aurora instance. Most instance types returned an error but using t3.medium worked, you can create that with public access.

7. when they are both created you can already try to ping your DB (it should work)

8. upgrade to 13.6

9. Now you are able to change the DB instance type to serverless

Edit: BTW I am available for hire as an external contractor for this kind of stuff ;)
Assuming that is true which very well might be, you still have to check every extension for telemetry as well.
Unless you change header files deeply engrained into your code base (or your entire code is templates), incremental builds should not reach 10 minutes, not to mention hours...

Wasn't it kind of the same thing in all the likelyhood? Their troubles became apparent shortly after, they were likely trying to get rid of employees people without making layoffs apparent.
I think Tesla (partial) self driving cars have the lowest accident rates.

Cyber security is a real concern though, imagine a mass hack terrorist attack where everyone's Teslas start acting unsafely simultaneously. If I had a self driving car I'd want a hardware kill switch.
