Most interesting tidbit:

We expect that a significant portion of our initial revenue will be from one customer that is an affiliate of one of our principal stockholders.

If we are unable to maintain this relationship, or if this customer purchases significantly fewer vehicles than we currently anticipate or none at all, our business, prospects, financial condition, results of operations and cash flows could be materially and adversely affected.
To date, we have generated minimal revenue from the initial sales of our R1T vehicles and have not generated any revenue from the sales of our other vehicles. Our future success depends on us commencing commercial sales and attracting a large number of customers for our vehicles. In the near-term, however, we expect that a significant portion of our revenue will be from Amazon Logistics, Inc. (“Logistics”). Amazon is the parent company of both Logistics and Amazon.com NV Investment Holdings LLC (“NV Holdings”), which owns approximately % of our voting power as of , 2021.
In February 2019, we entered into a commercial letter agreement with Amazon, and in September 2019, we entered into a related framework agreement with Logistics. We refer to these agreements, together with any work orders, purchase orders, related agreements and amendments thereunder or thereto, collectively, as the “EDV Agreement.” Under the EDV Agreement, we and Logistics have agreed to collaborate to design, develop, manufacture, and supply EDVs and/or certain component parts and related services for use in Amazon’s last mile delivery operations. We also have agreed under the EDV Agreement that until the fourth anniversary of when Logistics first receives EDVs (the “Initial Delivery Date”), whether or not Logistics purchases any EDVs from us, we will exclusively provide last mile delivery vehicles to Amazon, and from the fourth anniversary to the sixth anniversary of the Initial Delivery Date, Amazon will have a right of first refusal to purchase last mile delivery vehicles that we produce. Under the EDV Agreement, Logistics has the right to decide how many EDVs to purchase, which may be fewer than expected, or delay the delivery of such purchases. Certain factors outside of our control may influence Logistics’ decision as to the number of EDVs to purchase from us and the timing of delivery, including Logistics’ ability to deploy a charging infrastructure across their delivery stations.
Again, I'm not saying they're perfect — only that there's a real business unlike a cryptocurrency. It might not be printing money like Google/Facebook ads but it's highly unlikely that the business could not turn a profit, albeit a tighter one due to competition.

Contrast with a cryptocurrency: there's no value other than marketing and nobody needs to use it at all, much less any particular cryptocurrency over an alternative. That puts your floor value at zero: unlike cars, nobody needs random hashes and certainly nobody needs to buy your hashes over equivalent hashes available somewhere else.
> Sure, but should we take the possibility of mixed compromised interests as a reason to stick to the known compromised?

Again, I don't see the difference. I think compromised news is the best we can hope for, and we just need to get better at living with it.
I think this kind of imposition is frustrating not because of the end result (we'd all appreciate more diversity, no doubt) but because of the method: is painting over the symptoms a meaningful solution?

Maybe we should discuss instead what's leading to such lack of diversity (misaligned incentives? lack of opportunities?)
Oh cool! I've wanted something like notion for years. Ideally on top of CRDTs (so I own my own data). I really appreciate all the work your company is doing! Feel free to get in touch if you want to have a proper chat about this stuff.

> My biggest open question is how to design my centralized server side storage system for CRDT data. To service writes from old clients I need to retain a total history of a document, but I don’t want to force new clients to download the entire history nor do I want these big histories in my cache, so I end up wanting a hot/cold system; and building that kind of thing and dealing with the edge cases seems like more than 100 lines of code.

Yeah definitely more than 100 lines of code. I'm sad to report that in diamond types (my own CRDT) I've spent ~12000 lines of code in an attempt to solve some of these problems. I could probably get that down under 3000 loc in a rewrite if I'm happy to throw away some of my optimizations. Doing so would dramatically lower the size of the compiled wasm bundle too - though the wasm bundle is still comfortably under 100kb over the wire, so maybe its fine?

Regarding history, I have a lot of thoughts. The first is that with the right approach, historical data compresses really well. Martin Kleppman's automerge-perf data set has 260k edits ending in 100kb of text. The saving system I'm working on can store the entire editing history (enough to merge changes from any version) in this example with just 23kb of overhead on disk. I think that resulting data set might only need to be accessed in the case of concurrent changes, and then only back as far as the common ancestor. But I haven't implemented that optimization yet.

And yeah; I've been thinking a lot about what a CRDT-native database could look like too. There's way too many interesting and useful problems here to explore.
I want to redistribute more wealth to poor people, and I don't give a damn what colour the rich people sitting on corporate boards are. Americans have a myopic obsession with the race and gender of their rulers, but are willing to let the crippling poverty and poor working conditions of their neighbours slide.

Progressivism sometimes takes time and energy that previously went to helping the working and middle classes, and redirects it off into the aether to help the very top of the pile.

Ask HN: Requiring browser cache / IndexedDB for SaaS app?
I'm developing a desktop SaaS app that relies heavily on local browser caching, using IndexedDB. This is to reduce server load. This is a part of the business strategy.

I am making IndexedDB a requirement to use the app. IndexedDB is available on 97% of all browsers. If IndexedDB support is not found, I will show a popup.

Is this reasonable? Do you thinks users would make a fuss? Are there any corporate policies that disable the local cache, or clear it when the browser closes?

Not really. “only”, no. Trying to levitate trains with static charge would introduce all kinds of hard problems, some easy to imagine, some probably would take a lot of engineering to discover.

The electric field would be hard to contain just under the train, the charge would really really try hard to find somewhere else to be, there would be some crazy ionization of the air going on… flying a kite in a thunderstorm would probably be quite safe by comparison to being close to such an apparatus.

Equity by its normal dictionary definition is great.

But as the critical race theory worldview defines it, "equity" involves unequal treatment of people and discrimination (decisions made about how to treat people) on the basis of race.

The idea is to retroactively create equal outcomes, not equal opportunities in the present.

The problem is: a society can't create either equal outcomes or equal opportunities by intentionally discriminating one way or another, since doing so (1) fails to solve problems at their source and (2) creates new problems.

In other words, love is the answer, not hate.
It's getting a bit crowed in the EV market-space and some EV makers like Rivian need to do more than their competitors otherwise they will end up being yet another EV maker, which now is not enough.

The Amazon fleet partnership is very positive and several other deals in Europe too. However, Rivian just needs other ways to utilise its technology just like what NIO is currently doing in China.

If Rivian follows that path and avoids being just a generic EV maker, then its stock is a straight buy in my books but I would hold for now and see what the competitors (especially Lucid Motors) are also doing first in October.
Belowground is often better, and was widely used, but then you have to arrange water drainage for the hole, or the ice or groundwater soaks your straw (Zimri-Lim didn't have styrofoam). On the side of a hill or in a sandy desert that's not too hard, but when you're digging below the water table this is a real problem if your sump pump is just a shadoof, and especially when tadelakt is the state of the art in waterproofing. Zimri-Lim may not have even had tadelakt, and he definitely didn't have waterglass, and possibly not enough pitch or tar to waterproof a whole icehouse. Almanzo Wilder's childhood icehouse was (if the novel is accurate on this point) actually up on stilts, presumably to guarantee drainage.

(Stationary air outside a wall adds a little more insulance that dirt won't, even dry dirt, but I think it's too small to matter in this context.)

It's desirable to store your ice well below 0°, as you say, but if the only thing you have to cool it with is ice, you don't have a choice; you can fill your icehouse up with beautiful ice at -20° if you like, but its specific heat is only 2 kJ/kg/K, so after 40 kJ/kg leaks through your insulation it's all up to 0°. Avoiding this requires more than an order of magnitude more insulation than simply keeping the ice from melting before next winter: instead of 100 mm of straw you might be talking about 2 meters, or more if your icehouse is smaller than the humongous 10×10×10 cube I chose for calculational convenience. (This is also why icehouses were not useful for freezing, for example, meat, but only refrigerating it; consequently Argentina's economy didn't explode until 01883, because exporting fresh mutton and beef was impossible.)

You may be able to solve this problem by salting water, which can actually produce a mild refrigeration effect, but eutectic segregation may sabotage your efforts to do phase-change thermal energy storage that way; that's why I mentioned eutectic aqueous sylvite, which I think is the most suitable choice for solving that problem in modern solar-powered domestic freezers.
They're similar. However, an AFM directly measures the deflection of a probe you're rastering, while a STM measures the current caused by quantum tunneling between the probe and the sample. This is extremely sensitive to height because an electron's wavefunction degrades as e^(-sqrt(2*m_e*E)*x/hbar) with distance x and energy barrier E (the measured current will scale with the wavefunction^2). Additionally, a STM allows you to probe electron states as well as just topography.

I prefer a simplified version:

Fossil fuel + O2 --> Money + Waste + CO2

Money + CO2 --> Fossil fuel + O2 + Waste

The problem is that each conversion is not 100% efficient, so the net reaction is

Fossil fuel + O2 --> Waste + CO2

In the thread there is a drawing that explain this more visually.

There are some chemical process to transform one fossil fuel into another, you can "steal" the hydrogen from oil and you get energy and coal, but I'm not sure if it's profitable if you are going to burry the coal.

A big reforestation may work, and then charcoal and bury it, but no country offers a lot of the surface for free. It's probably better to use the surface to get biodiesel and ethanol, and replace the fossil fuel with carbon neutral fuels.

You seem to think that hiring decisions aren't already largely made on the basis of race and gender.
> If you don't have diversity at scale, in so many senses of the word, your [sic] doomed to fail anyway.

Then why do we need a law banning it? If these white-male-only-board-led companies are doomed to fail, they should be outcompeted by sufficiently-diverse-board-led companies.

I have a feeling the physical attributes of the board doesn't actually matter when it comes to a company's performance.
“Privilege” is getting a job over a better candidate just because of inclusion in an artificial social construct.
> They aren't saying, "you have to hire this person". They're saying you can't hire exclusively this type of person that currently dominates the top of society.

No, that's not what Federal anti-discrimination law says. It only says you can't refuse to hire certain people on the basis of a protected characteristic (of which race is one, but not the only one). It says nothing about refusing to hire certain people for other reasons that don't have to do with a protected characteristic.

(Btw, corporate boards of directors aren't even "hired"; they aren't employees. So it's not even clear what, if any, Federal anti-discrimination laws about hiring and employment would apply to them.)

> Given that these boardrooms don't diversify themselves, what is the actual problem with it?

There are two actual problems. One is that you can't have a government that only exercises its power wisely. For every mandate the government makes that happens to move things in the right direction, there will be many more that move things in the wrong direction. The people who are attracted to government jobs where they get to tell other people what to do aren't benevolent helpers; they're people who like power. All history shows that such people are precisely the people you don't want telling other people what to do.

The second problem is that dictating that people of certain races must belong to corporate boards is just as wrong as dictating that people of certain races can't belong to corporate boards. Both are looking at something that is irrelevant to the actual job, which means they aren't actually improving the corporations; the corporations can still do just as much damage as they did before, just now they'll be doing it with a "diverse" board.

The only real way to fix corporate governance is for people who would do better jobs than the board members of current corporations to form their own corporations and out-compete the current corporations.
While we are at it, just off the top of my head, lets make it required to include at least one bald person, at least one person with blood type AB, and at least one person with freckles. We shouldnt descriminate against them should we?
Thank you for the explanation. I said it was a guess, and it wasn't too far off; either way it's literal patriarchy embedded into the language. I wonder if people's authoritative tone (and downvotes) would change if they discovered that there was also another language where the distinction was meaningful but based on different reasoning.

I think it's more complicated than that - it was certainly owned entirely by Volvo as recently as 2015 and seems to share basically all engineering resources with Volvo. Seems like a funny attempt somewhere to make it seem like something other than Volvo - not sure why as Volvo has a reputation that's fairly decent already, if a bit dull and parental. I guess that's why Polestar is separate - to be more fashionable. Polestar still 'engineer' Volvos - I think it was at some point like BMW's 'M' thing - like a badge?
But these are board positions. They are not chosen based on measurable skills, but rather almost always on some combination of connections and a specific mindset.

This has often been called the "old boys club", and the persistent pattern of boards being overwhelmingly white and male is great evidence that there has a (predominately unconscious) bias in the selections.

Since the makeup of these boards affects the decisions made by these companies, and those decisions have a large impact on society, society (California) has decided that they have to clean up their act and make those decision makers at least vaguely reflect the makeup of that society.
I think discriminating based on race and sex (for hiring decisions) is already illegal. Therefore, the only new scenarios covered by this law are where a board ends up being single-sexed and -raced for reasons that one can't make a strong case were due to discrimination.

The Dangerous Myth of Health Service 'Collapse' – The Daily Sceptic
It's not just individual scientists (who certainly aren't going to seriously entertain every crank they encounter - that would be insane), but institutions that hire based on expertise, consider which papers to print based on expertise, and so on. In science & other expertise-driven fields we assess competence & credibility when hiring, judging proposals, tenure, awards, research, etc. CVs & history are relevant and considered. That's the way an institutional expertise-driven domain like the sciences works.
We seem to have been misguided by all of the Amazon RDS and Aurora documentation. It seems Amazon prefers to implement postgres logical replication through their database migration service. All upgrades are typically done through pg_upgrade which does require downtime.

As a reservation holder myself I don't really consider "delivering" to employees to be releasing a product. Employees aren't free to discuss flaws or other problems and no doubt get priority for fixes/repairs.
I am not saying this is the cause, because I’m not American, but maybe Americans use it in a more “harmful” way. Where I live people mostly use Facebook to buy used stuff on the Marketplace and to post memes in their hometown groups.
That's not really the opposite. That comment with the correction is a part of the submission that's being upvoted.

I do this myself, too: if the discussion underneath a HN submission rescues an otherwise bad article, or even develops into a completely unrelated but interesting tangent, I'll happily upvote it. Sometimes the only value of the submitted article is in the discussion it starts - but that still makes the particular submission valuable.
