Well, for VW specifically, I remember seeing a Jetta review from SavageGeese where he explained VW was able to improve it and make it cheaper at the same time by putting it on the same platform as the more expensive cars and just making it more modular.

So at least part of the reason would be improvements in sharing reusing resources between models increasing the economies of scale.

In general, car manufacturers also removed stuff people don't care from lower models like better rear-suspension. You also save costs by going electronic e.g. the steering wheel isn't connected to the wheels anymore, it just tells them to turn by wire. Same for the transmission, that's why cars are getting rid of the transmission lever in the middle and using weird buttons instead : it isn't actually connected to the transmission box anymore. This also extends to removing physical buttons/volume knobs.
We already are at a demographic cliff as older boomers begin to pass and younger boomers are retiring. Baby boomers are the largest generation in human history and it's looking like Millennials and Gen Z will not have nearly as many kids as their parents and grandparents. So even if they do want to own houses as much as boomers did, there's going to be a lot less of them to absorb the supply of housing on the market over time.
Yeah the idea is the trains are filled with tons of weight.

In my head it still seems like it would be cheaper than digging out massive reservoirs for pumped hydro. Rail seems relatively cheap even if you do have to replace it regularly because of the wear. It also seems like you could put the rail in all sorts of geographies, big and small. Maybe it isn't worth it unless you go big though... and at that point why not hydro.

It's good questions though. No idea how the economics of it will work out vs pumped hydro.
- Increased wear on all powertrain components

- Decrease the lifetime of your tires by 1/2

Wait, what?
Only if any of those passing cars are gas-powered. If the passing cars are themselves also EVs, then there's both more obvious forms of energy transfer, but also you'll be taking that much range (and more) from the EV doing the towing.
> What kind of shitty train does only 50mph?

In the US, Amtrak shares rails controlled by the freight operators. Amtrak trains can be delayed indefinitely, as the freight trains always get priority, even when they are off schedule. These delays are unpredictable in timing and length.

I used to do the Seattle/Portland route regularly and 1 - 2 hours extra/unplanned travel time wasn't uncommon. Average speed was well less than 50mph.

I don't think this response is very coherent. As I pointed out, you can face the same "serious" consequence simply for calling someone a bad name. What you're saying would make sense if we were discussing convicting him of a crime, but that's not what we're talking about; instead, his defenders are moving the goalposts, so that we use the standards of evidence of criminal conviction and imprisonment to enforce standards of social and commercial behavior. That doesn't make sense, sorry.
I realise this is a controversial view here, but in my opinion the real question is really whether you value Apple’s freedom to build what they believe is the best version of their product. You might not care about that, and that’s fair.

Personally I think they should have that freedom. If Apple really had no competition, I would absolutely change my mind. But so long as Android exists, my view is that consumers deserve the right to choose Apple’s garden if they want. And they can choose to leave it. Millions of people do every year. Let the market decide.
A lot of people recommending this (off HN) but I feel like there's more potential elsewhere

See: https://www.bloomberg.com/news/features/2020-04-01/how-much-...

"In Red Oak, Texas, a town about 20 miles south of Dallas, Google wants as much as 1.46 billion gallons of water a year for a new data center by 2021, according to a legal filing."

The legal filing: https://interchange.puc.texas.gov/Documents/49863_21_1037351...
The 1.46 billion gallons of water _a year_ figure comes straight from this filing. Divide by 365, that's four million gallons a day, way more than 1.25 million.

Could you expand on how something might be wrong with the reporting when by Google's own account it is planning to build datacenters that use this much water a day/year?

More:

"Google’s data center water use became a subject of controversy last year in Berkeley County, South Carolina. An environmental group opposed the company’s request for 1.5 million gallons of groundwater a day from what it said was a “historically threatened” source.

The company has also worked with Berkeley County Water & Sanitation to get 5 million gallons a day from the Charleston Water system. Google said its share of this supply is far less than 5 million gallons a day, with the rest available for the broader community."
Interesting. The first thought that comes to mind when I see that circle is Apple HQ.
I worked as a manager at a FAANG for 2 years and switched back to IC. It was fairly common practice at my company, even among directors. I actually preferred the management role, but felt like there were many downsides.

1. I wanted more flexibility in hours and working remotely. I have elderly parents in another state and want the flexibility to support them, as an only child.
2. Level of support. Most directors talked about taking all their vacation at once to relieve pressure to constantly check messages during vacation. For me, it was a < 1 hr response, much like lawyers. I was constantly pinged if I ever slacked on checking.
3. I felt like line management was much less emotionally supported than ICs. It was pretty common practice to give any positive praise to the IC and negative feedback to the manager, regardless of any sensical attribution. This was fine for optics, but frustrated me that it extended to internal reviews.
4. The power dynamics mean that any of your IC friends now have at least a minor level of suspicion towards you. Other managers also have hostility because advancing feels more zero-sum unless the company is hypergrowth.

I miss being a manager, but my mental health is a lot better. Honestly, I felt like I provided more value to the company as a manager and had a great relationship with my team that continued after I stepped down. It's not my evaluation process however.
I don't think this should be solved with tags (or other OOB methods). Just set a "loop" flag in the container (or metadata). GIF is perfect because it doesn't require ANY additional info when it comes to looping or animation.

Any format that doesn't have this is doomed to fail as a GIF replacement.

> Metaphysics = the physics of physics

Metaphysics isn't really the "physics of physics" though. It is part of philosophy, not physics. It isn't even the "philosophy of physics", since that names a branch of philosophy distinct from metaphysics (albeit they do have some points of overlap.) This is an example of where the meaning of a term is different from the sum of its parts.

The philosophical implications of quantum theory (and its interpretations) is one part of the philosophy of physics, but the study of those implications go beyond just metaphysics proper and also extends to other areas of philosophy such as the philosophy of mind, epistemology, the philosophy of logic, etc. Conversely, there are some debates in metaphysics with which contemporary philosophy of physics doesn't concern itself with much, such as the relationship between existence and essence, or the problem of universals.

Just a little conjecture here, but i find the whole experiment fascinating.

A tesla model S is around 5000 pounds. not the lightest car on the road by any standard...but towing it behind a consumer Ford F150 will drag the mileage of the truck to 14MPG. not too shabby compared to your long-haul tractor trailers that get about 6...but thats the free rolling weight of the vehicle, not its weight with regenerative braking turned on. id be very curious to know what the final hitch and tow weights are respectively.

from what i can tell, a supercharger will get you charged in about an hour. so...70 miles? most trucks cant maintain that speed in hills or corners, so unless you live in nebraska, youll be on the road a lot longer than an hour. other states might not let you hit 70 at all....can it be done at lower speeds? given the wind conditions on any given day, you might not be able to safely maintain a 70mph tow. other states (california) impose tow restrictions on just how fast you can go.

RV owners probably wont buy a tesla based on this knowledge but id love to see more data from this kind of testing...could the energy from the regeneration be used to charge RV batteries too? can this regenerative system be applied to trucks to power heaters and air conditioners during layovers and downtime?

> Yes it does. I use it everyday. Which Apple TV do you have?

4k - 1 model older than M1. I don't mind buying a Homepod to enable it (I'm not happy about it, but less happy about being forced to do it with iOS devices not designed explicitly for hearing you anywhere in the room), but to my knowledge commands from the Homepods won't make it to Apple TV. Am I wrong?

They are still considerably worse than older Macbooks, since thinness and removing the ability to upgrader hardware were the priorities. The only thing that keeps me in the Apple computer ecosystem is Mac OS.

I'd hope they have a "panic" mode that at least "safes" the car.

It's also worth pointing out that humans are notoriously bad at "exceptional cases" sometimes. People full-stop on the freeway for small animals to cross sometimes or panic when adjusting their eyes out of tunnels.

I do think it would be interesting to compare the two (computers vs humans) and look at the venn diagram of crash cases.

It would only do this if LVT were significantly higher than property taxes. Because property taxes already includes the value of the land.

E.g. my "house" is valued at 700k. But the appraisal puts that at $280k structure and $420k land. 1% of 700k is 7k, but 1% of 420k is 4.2k.
Generally this is true, but in the safety critical domain you don't gamble. You do your homework and make sure you aren't exposing your users to unnecessary levels of risk.

If Tesla was developing their system with trained safety drivers or on closed courses, I think they would have higher moral ground to gamble here. But placing the untrained public behind the wheel of alpha quality software is unethical IMHO. There ways to develop autonomous software that are significantly less risky, and the only reason Tesla is doing it this way is for marketing/PR purposes as far as I can tell.
It's very clear that our (Strayan) government will sacrifice anything on the altar of the housing bubble, because that's what the boomers demand, and they're still in charge for some reason. The rest of us get the shaft.

This is exactly the feeling I had when visiting the Seneca Pumped Storage Generating Station that I mentioned in one of my other comments that I just posted before seeing your post. Truly awe inspiring. (Links provided in my other comment). Do go visit one of these!
Most (all?) CRT TVs eventually turn everything into an RGB signal before it goes to the tube itself, this is generally what most on screen displays feed into. So you could add something in that also feeds into that line.

Some people mod RGB into composite only CRTs this way for retro gaming.
That's a problem for deciding which system drives the thing (eg. do you use cameras for detecting oncoming cars and objects or lidar/radar), but if there are major disagreements between them it would make most sense to disengage the autonomous part and ask the human driver to take over, much like current TSLA cars do. Obviously not possible if you want level 4 self driving, but it can be good enough for level 3.
I got pulled over for this. I was driving home from a friend's at about 2am so nothing but clear roads, it was on about a 10 mile stretch of dual caradgeways with a few roundabouts along the way. At the 3rd roundabout I got the flashing lights and dutifully pulled over. Turns out they pulled me over because they thought my break lights were out. After a quick demonstration of my fully working break lights and a quick chuckle between myself and the cop I was off again.
I will offer my perspective, and this is not to disparage or dispute anyone else's experience at Amazon or any other company.

Personally, I worked at two companies before Amazon.

I left both companies because I was unhappy. Two people from my last company also left for the same reasons I did. One of them is at Amazon, and the other one is at SalesForce.

Does my experience at my last employer represent a systemic problem in their work force? Probably not. I did know folks who were plenty satisfied and didn't leave, who didn't follow me even after I tried to recruit them.

All I'm saying is – it's easy to draw a conclusion and the wrong one. When you have a company that hires at Amazon scale, 1% of your workforce being unsatisfied and some percentage of that 1% willing to speak out about it means you have a lot of negative press. At that point, your rival companies, especially in the news media, have plenty of ammunition to run campaigns where that 1% seems like it's 80% or 99%.

Lastly – there is a negative Amazon article on HN just about every single day, and from reading those articles, it seems like people out there wish my mental was suffering or I hate d my job, even if I feel great and like the people I work with.

So here's the thing: if housing prices crash you still have a house.

Maybe. Generally the economic turmoil around a housing crash means many people will lose their jobs, so they may or may not be able to afford to continue to own their house. Which is why so many houses end up getting foreclosed during a housing crash - people can't afford to make the payments, and they can't sell and pay off the loan.
There's certainly some of that and I have experienced project managers asking me to put 5GB datasets in spark... but there's definitely a set of problems where vertical scaling is a PITA and MPP basically generally breaks the SQL guarantees anyway, costs a milli, requires rewrites, etc.

When you want to process N+1 TB/PB its hard to throw standard relational approaches at it imo.

I think you point to the basic question here: is it fair to only judge him for the things he has apologized for and taken ownership of, or would it be moral to form and act on our own opinions?

If you feel it's only appropriate to judge people on the behavior they admit to, then I think your read is correct. That also, to me, feels like it becomes tautological - it places the locus of power on the accused and the onus of coming forward on the victim.

We want some level of responsibility on the victim. False accusations exist (though research suggests they are extremely rare). I don't have good answers - but someone asked what more someone could want and I answered. There are parts of how he talks about the experience that make me uneasy. I can understand that unease making others uncomfortable.

The line I would draw is one of looking for reflection on personal behavior. As I said in my post, I'm not comfortable accepting his description of the events as the end of it and I do not see any understanding of why that might be in his answer. I don't think he needs to have intended to commit sexual assault to have done it and I don't think someone needs to accuse him (privately or publicly) for him to reflect on the possibility.

I said elsewhere that I would work with him, but I would certainly understand if people didn't feel comfortable about it. I guess I've seen many people leave companies or not get hired for far more mundane interpersonal mismatches. It is really hard for me to take seriously that cultural fit matters at work, but that people must accept a former abusers' representations they have changed.

I also just want to say:

>[the companies fired him] based on fear of social media.

I have no idea if this is true and neither do you. I have seen external embarrassments handled in different ways and I am skeptical it was this simple. Of course, I could be wrong, but there are plenty of prominent figures who had accusations made against them and they either kept their jobs or found new positions.
you're saying housing prices should increase because land is finite and therefore scarce. but there is so much land in the US and more empty houses than homeless; even in expensive neighborhoods a lot of housing scarcity is artificially created by zoning policies for upper middle class residents with a vested interest in keeping their house valuable. and that's not even mentioning that the physical house itself (as distinct from the land) should generally depreciate in value as it ages and requires more maintenance and stuff replaced. same logic as a car

I've wondered about bitmap indexing before. Is it an optimization for speed, too, or just memory?

If I had an array of a million things, and I wanted to specify some large subset of them via a separate million element array (like in numpy/pandas), is it faster to do it via a million bytes or via a million bits (ie I think this is bitmap indexing, right?). I would think that the bytes would be faster, even though terribly wasteful of memory. From my rudimentary knowledge of CPUs I thought they didn't really operate at the bit level, and so you'd have to do a few instructions of calculations. Or would it be made up for by the cache line reading in more of the indexer in one fetch?
