I don't know much about the technology - the lack of larger installations is a red flag. Anyway, I tried to calculate with the numbers from the document above with the following assumptions:

10 charging stations, 6 cars per hour per station, 100 kWh per car. That makes 6 MW peak consumption for the whole "gas" station. A capacitor storing 6 MWh (60 cars served, no incoming electricity) would need to have 120 m³ of storage. Google says that a gas station storage size is between 30 000 and 40 000 gallons (110 000 - 150 000 l) so that seems comparable. Another way to look at it - 200 m³ of storage is a building of 10 x 10 x 2 m, without the need to manipulate flammable liquids.

Not sure about the investment costs (the doc says 5 000 cycles but no cost estimate), how long the peaks are and other aspects of running a gas station. Still, it seems the order of magnitude is about right.
In terms of performance, I'm not sure, although I'm willing to bet on Pinecone as they have their own proprietary indexing algorithm. I can speak in terms of developer experience though, as I did use Pinecone to build this app. One obvious but important difference is that with pgvector, you need to spin up and self host a postgres server on your own. Pinecone provides a batteries-included, fully managed experience. Also, it seems that a lot of important operations in pgvector are conducted with SQL statements. With Pinecone, you don't need to deal with SQL or with any ORMs.

In terms of this project, I would not have chosen pgvector. I don't want to deal with the PITA that comes with manually setting up and self hosting a vector database. When I'm building a demo or a prototype, I care about speed of development, which lets me more effectively explore the possibility space of whatever I'm building. I'm not a database admin, so when I deploy the project, I don't want to do database admin tasks. The ease of use of Pinecone's API lets me move fast, and it was very intuitive to learn. One downside of Pinecone is that although they have a generous free tier, their next highest tier is $50/month (and that's the low end of that tier). This is unfortunate for solo devs like myself who are likely to graduate from the free tier and would be willing to pay a bit more for a higher tier, but find the $50/month plan to be overkill. I think they're trying to target startups with that $50/month plan.
Check out the Maslach Burnout Inventory.

The main symptoms include emotional exhaustion, depersonalization, low self-assessment of competence and success, low productivity, and cynicism.

Recovery may take over a year, though, so plan around that.
Let me drift off a bit.

I want to mention that not 100% of our time needs to be spent on something "useful". While it's something everyone needs to define for themselves, recovery and enjoying life outside of what is deemed "productive" is also very much important. I am writing this because I have personally been affected (as bystander) if people don't take this seriously.

For Germany, I can say that in recent years, health insurances are reporting a very significant increase in burn-out cases which easily take months of recovery and are a very significant problem in the economy with high financial impact on both society and individual lives.

Maybe it has to do with the type of work we do nowadays, or it has simply become more acceptable to openly tackle this issue instead of hiding or dismissing it. I don't know. But I have personally witnessed several people (!) go through this and it's terrible. Hiding it doesn't mean it isn't there and ruining lives behind the scenes.

The 1800s was a different situation altogether and time-wise probably one of the worst periods to be alive as working class. 10-16 hour workdays, repetitive and physically demanding work, no rights and barely any medical attention. I am very certain that people didn't just "toughen" that out, it had to come at a very high cost.

Likely we'll see such a system with electric motorcycles (and similar categories) first, which is like a "small scale" version due to the smaller battery capacity & size.

E.g. Honda is working on it: http://www.honda-mpp.com/in/
It doesnt need to completely disconnect from the grid, just smooth the load as much as is economicallly useful. A load that is already statistically smoothed by multiple cars charging at once, arriving and leaving at different, but statistically predictable, times.

And people are already attaching batteries to the grid to earn money by smootging supply and demand, it just makes sense to locate those near to demand so they can share cables. Then to the grid the car charger station looks like a consistent energy user that can flex a little to help the grid (possibly even feeding back during peaks), rather than a random one.

None whatsoever. There are some Russian appologists making the rounds. Fact of the matter is that Russian oil exports are in decline, but the rising oil prices has made up for the difference. This increase is not sustainable. To get back to pre february export levels, Russia has to build a pipeline to China.

> Though Russia’s fossil fuel exports have started to fall somewhat by volume, as more countries and companies shun trading with Moscow, surging prices have more than canceled out the effects of that decline.

From what I've seen, there's a largely negative sentiment towards BTC. That would lead to better reactions when a massive sell-off happens as compared to the opposite.

Some top arguments I've seen are: pyramid scheme; "tulip mania"; wasting electricity / bad for the environment; fosters some amount of crime; doesn't help core use cases that much (anonymity, flexibility, actual decentralized payments).
I think the general opinion people on HN show is that the crypto community make many claims about cryptocurrencies that are true in theory, but false in practice. And then there's the blatant scams and Ponzi schemes.

> We are in an ideological trap, blaming Russia for everything.

The ideological trap is not only related to Russia but to everything. The West uses - as you also point out - ideology for everything: Pandemic, migrations, climate, culture, economics... Those who don't want to play along are blamed. The West thinks it has a leverage over the World Outside of the West but that isn't the case anymore. Both the elites and the people in the World Outside of the West realize it and they are turning away, leaving the West in it's own echo chamber.

As I wrote here three months ago: The West is ~1 billion people, the World Outside of the West is ~6 billion. The West needs the World Outside of the West for its own enrichment through robbery and enslavement, World Outside of the West doesn't need the West because it doesn't want to be robbed and enslaved by the West anymore.

I think someone else mentioned that lack of progress/control is what causes burnout. Generally, vacations make you lose control.

Depersonalization and cynicism are symptoms of burnout. But I think vacations solve burnout the same way that tissues solve colds. It's something you reach for instinctively.
Not doing simple mistakes that kill performance for no benefit or choosing option B over A where both take equal effort but B is 20x times more performant should be common sense.

The full quote from Knuth is this;

“The real problem is that programmers have spent far too much time worrying about efficiency in the wrong places and at the wrong times; premature optimization is the root of all evil (or at least most of it) in programming.”

In your example clearly if there are two approaches and one is 20* faster than the other it's optimization in the right place.

But... it's the "at the wrong times" bit that's actually the most important part. If you have a working solution and you're spending time trying to make it faster without knowing it's too slow then you're trying to optimize at the wrong time. If you know both approaches then it's fine, and good, to pick the faster one. If you don't then you should use the one you know and come back later if you need to.

Most of the time you won't need to.
> I use KDE now as main driver which has a ton of options compared to macOS and they use the same format.

Those of us who remember the old tree-based layout from before Kirigami took over were about as happy about the change as macOS users are about the new Preferences layout in Ventura. It used to look like this a long time ago: https://fedoranews.org/krishnan/review/kde3.2/fullsize/contr... -- it was a lot more space-efficient and going into one sub-section didn't automatically hide all other sections, so it was a lot easier to look for things.

I don't recall if the window in Plasma-era releases was resizable but it certainly replaced one that was both scrolling and resizable. Early 5.x releases still supported the tree-based layout IIRC but it hadn't been the default since the 4.x days, which used that awkward icon-based layout, eek!

> It's deserved because of how much better his company is, compared to others doing the same thing.

That's not only his merit, it is the merit of all of the workers of Amazon (plus a massive dose of luck).

> That's his contribution as an owner, as opposed to a worker.

No, it's not. His only contribution as an owner is putting down the original capital to buy the PCs and offices and books. All his other contributions in leading the company and deciding what paths it takes are as the CEO, a worker.

> The difference is choice.

Yes, and people often don't have a real choice: in certain areas, they either work for Amazon or go without food while trying to learn a new skill/move to a new city.

> plantations weren't that efficient, actually. It was a social self-perpetuating system that kept them going. Using employees and later machines was more effective for pretty much the whole human history.

They weren't efficient in terms of cotton yields, but they were efficient in terms of return on investment (until machines became widely available) - it's cheaper to buy slaves and have them work the land for some food and some shelter than it is to hire a worker a living wage for the same job, even if the worker has better productivity.
I... what are you doing that you need a 22kW charging station? 7 hrs to charge a 50 kW/h battery seems fine. Are you a taxi driver?

The amount of control American universities exercise over their students is mind-boggling to me. I went to Uppsala University in Sweden, which has a rich and varied student life. But none of that has anything to do with the University (any of them, there are 3 in town). The universities provide education, period. Housing is not run by the University, and it certainly has nothing to do with student social life.

What stops a bunch of Stanford students from starting whatever club they want in their spare time? Obviously it can't be on Stanford property, so maybe that's the difference, they have their students over a barrel because they can deny them access to housing which I guess is hard to find otherwise?

You can also have a large battery buffer supporting standard chargers. Or battery integrated chargers are also interesting because they're fast to deploy and cheap to install (though the individual units are more expensive due to the battery):

I somewhat share this view, which I now learn is called Copenhagen Interpretation of Ethics (don't know if by the author or academically). Let me clarify my differences: interacting with a problem should be worded like "creating the definition of a problem". This changes things because saying things, as I view the world, is an action like any other. But my conclusions from this are the opposite of what the author ascribes to this Copenhagen school: defining a problem is an action, helping a few bums is another action, and generally it's considered a good one (especially by the helped bums I think). So it's "good" (I handle this term with great care...) I think the problem lies in the following assumption nearly every people makes, even relativistic people, especially those who doesn't really reason about ethics: an universal good exists and must be "found" in every instance of every problem. My point of view is that there isn't nothing to be found, we create what we create, so let's create a little help for some bums.

> I keep holding out for LASIK but don't know how much longer I should.

I think the Holy Grail should be eye surgery that is a permanent fix. Current options wear off with age (and not that many decades at that), and then you are back to corrective lenses. There are usually very few who can qualify for another surgery later in life...and then it wears off again anyways. It's a consumable elective surgery that consumes the benefit and the body, so in my opinion it is a net loss over the long haul.
Selling less for more of a finite resource seems more substainable.

If you want to go by worker preference, then you should also do that with unions: the workers are trying to form unions, and have some mild success despite massive illegal opposition and repression from the company - so, they must be unhappy with the working conditions.
Ok, so there's a key point here, and that's that fast charging is not meant for the home!

You can fully charge an EV overnight on a 7KW charger. You don't need a fast charger at home.

The other thing is that home chargers are AC and the car converts the current. This means that there's a cap to how much power you can give it. For example, my car can only accept 11KW and that's pretty typical. So 22KW chargers are a waste at home today.

Maybe you'd need a fast charger at home if you never sleep. But the majority of people spend at least 7 hours at home. You'll always wake up to a fully charged car. Why do you need anything else?

This is def a decent counterpoint - on a previous HN thread on this topic I recall studies being done on agricultural vs urban mainland chinese people and how a refinement to the observation so sunlight/outdoors might be a proxy for some other factor. I've seen proposed "distant viewing".

Although one possible nuance is that sunlight to the eyes != sunlight to the skin. In cold climates you wear thick clothes which will block out sunlight to the skin (vit D deficiency) but you may still get plenty of UV to the eyes. Throw in some mountains for distant gazing and suddenly nations that love skiing could be simultaneously vit D deficient but guarded against myopia.

>I want my pet taken care of

Strict regulations don't guarantee this. Additionally, they can be counterproductive by blocking competition, resulting in only a few compliant vets in your area who might still harm your pet.

>I don't want to sue... courts are not efficient
If a monopolistic vet knows they won't lose their license or face charges/fines because a court can't take do so, why would they be incentivized to be extra careful with your pet?
While not strictly useful at home, the problem of connecting to the grid would be the same for many places you could go and need fast charging.
No one needs a 22KW charger in their home.

The speed you quote for a shared 22KW with multiple cars charging is the same as a standard home 7KW charger (e.g. 60Kwh car charging to full from 0 while you sleep for 8 hours, or 2 of those cars charging from 20-80%). But no one drives that many miles per day consistently.

Most normal people can survive with a standard plug, even the 7KW is a luxury to let you think less about it and to help the grid by charging faster when the grid is off peak, enabling faster rollout of cheap renewables.
This revenue and num of users does not necessarily say the product has found product-market fit I'd say.

They aren't. It's a trash, deceptive article. This isn't to say SF doesn't have real problems (it has a lot of then), but I barely recognize them in this caricature of a piece.

It's worth noting that the author evokes the spirit of her great(-great?) grandfather in the opening paragraph, describing him as a humble butcher's mate. She omits to mention that he went on to become the largest private landowner in US history, at one point owning ~2 million acres of land in California, Oregon and Nevada with his business partner. I'm a little skeptical when someone who comes from extreme wealth tries to direct attention away from it.

Bowles repeatedly mentions old-time gossip columnist and SF journalistic institution Herb Caen, who died in 1997 only a short time after filing his last column. While lamenting that disappearance of 'Baghdad by the Bay,' his affectionate nickname for the city, she ignores the fact that SF was in the grip of a crack epidemic for much of the 1990s and crime was ~40% higher than recent highs. It was a lot more dangerous back then. The 1970s were pretty rough as well.

Bowles frames the recent DA's race as a confrontation between liberals and leftists, while skating over the fact that the recall effort was largely financed by conservative donors from outside the city, accompanied by a PR blitz heralding the result as a political sea change.

It's a superficial article that ignores the structural factors or historical context in favor of simplistic pandering.

$20k to install a 22kW charger!!!! i was quoted £1300 (uk) to have one fitted and i thought that was expensive!
to reply to another comment about why a 22kW is needed. if you're on a flexi tariff where energy price is super cheap from like 12-4am then having it fully charge in that time is needed to maximise the best price
> The entire equation whether you look from the employee side or customer side, has made the world better, the scale of which is difficult to imagine.

If I bring you the ingredients for a pie (say, worth 10 dollars), then pay you 10 dollars to bake it, then turn around and sell that pie for $1000, would you be happy with this arrangement? Would you say that you got a fair deal? After all, the pie is now larger, and I put food on the table for you, and I contributed to the $1000 directly, as you wouldn't have had the connections necessary to sell it for that amount yourself.

Anti-union behavior as "interfering" and "attacking" general principles like free speech is your own politically biased framing. Nothing wrong with that, but you could also frame it as supporting the free speech and freedom of assembly of capital owners/managers, or that unions are "interfering" with corporations. The difference between the two warring factions here is not social, it is economic.
