ICE engines need plumbing to fuel tank and exhaust, and they need a transmission. They also need a battery and alternator to power the lights, and either a starter motor or kickstarter to get the motor going.

In comparison an electrical motor is just a motor, battery and charger in the minimal setup
It’s interesting to see where the bottlenecks are. Some of these are clearly algorithmic and many are solved with simplifying the work or using concurrency, but a lot are platform-specific and nonobvious.
> Would raising the block size to 10-100MB cause significant latency issues for transactions even if one could fit a lot more transactions into a single block?

There are two ways to understand your question so I'll just answer both of them:

Fitting more transactions in a block leads to faster confirmation, and potentially lower fee. When a transaction gets into a block, the network confirms that the transaction is valid and can't be reversed. Right now each block can only fit ~2k transactions, and since a block can only be generated every 10 minutes, the mempool (backlog of unconfirmed transaction) is rather huge. This site shows how big it is: https://jochen-hoenicke.de/queue/. Miners are incentivized to only select transaction with high fee into the next block, which in turn incentivizes users to pay more fee to get their transaction to confirm faster. With bigger blocks, more transactions get confirmed quicker, which leads to lower fee.

Bigger blocks however mean miners with slow internet connection are at a disadvantage. When a miner finds a winning block, they broadcast the block to as many nodes in the network as possible. After a while, a majority of nodes accepts that winning block, and the miner is eligible for the mining reward. If A finds the winning block 10 seconds after B, but A is able to propagate their block quicker than B, then it's possible that A's block is accepted and not B'. In reality, it's possible that B might still win the race, but the rule is: faster propagation => more chance of being accepted.
Right now we're trying to electrify cars, but replacing cars with something else would probably work better for a lot of journeys. I think Sir Clive was correct about the concept of personal electric vehicles. The form factor of the C5 was nothing more than an implementation detail - with a few iterations it would have been significantly better.
I've been finding plain JavaScript as a very nice alternative to the many config file formats out there. It already has the trailing commas + comments bells and whistles, plus the ability to do computation to generate repetitive elements. Of course there's always the danger of the user creating a monstrosity of a 'config file' but if they're the ones using the software that consumes the config file, that's on them to keep the config file complexity down. Go already has a very useful JavaScript engine written in pure Go (goja), I recently opted for that as the config file format over templated JSON/TOML/HJSON or Starlark/Tengo because JavaScript is well defined and expressive. I'm thinking it will be a good choice for an authorization rules engine as well (over custom DSLs like OPA/Casbin) because using it is so much simpler if the user already knows JavaScript.

The form of the stroke is to increase the length of the downstroke.
So making power transfer happen as early as possible and to maintain it as much as possible at the base.
This translates into pushing forward and then down at the beginning and down and back at the end.

This efficiency simply means getting a longer ‘glide’

Don’t think about doing the « right » thing. Thinking like this is extremism.

What is important is acquiring the knowledge of your impacts.

Once you decide to acquire this knowledge, there is no more « right » or « wrong » way to act. There is only « reasonable », « unreasonable », « exceptional », « I don’t know let’s check this I’m curious ». You have the right to make the wrong choices as long as you are able to accept you were wrong.

What I like with this approach, is that it’s not self-flagellation anymore, it’s the joy of understanding the beautiful and complex world we live in.

You are not thinking about what the others do, you are just working towards being a better human. And this is easily transmissible around you without proselytism.

Here's what I wouldn't do: prejudicially dismiss the tribesman's opinion, citing his lack of authority on the topic.

Even if we accept the premises of an appeal to authority, it would follow that one would have to also be an authority on the topic before he could determine the authoritativeness of another speaker. How can you evaluate the authority of a speaker, if you yourself are not an 'authority' on the topic?

Even if you are an authority, does this status render you infallible?

No, I'm afraid the entire premise is ridiculous.

Why do you think TOML sucks for configuration files? I use it everywhere and it has been a joy so far. Granted, I only used it with Go, but it has been a great experience, and the configuration files are nice. For configuration files I would rather use TOML than JSON. For other stuff? I would probably go with ASN.1!

> there is probably no part that is not manufactured inside the country

May be before commenting go and look for statistics yourself if India is even considered a player in EV manufacturing market. Most of its EV startups and manufacturers rely on China, Korea and Japan for motors, electrical drive train, battery cells, PCB, elctronics and many core parts. India even imports electrical transformers from China, the most basic equipment for building electrical distribution network. [1]

May be talk to any auto manufacturers even most celebrated one's in India, have supply chain mostly from China. Go and ask Tata for its cars ECU, steering wheel and even steel. Indian mfg mostly are assembly and marketing company. China only recently became a manufacturer in EV and high speed train. It took over 3 decades of continuous improvements and development of close nit supply chain eco-system, India started opening up with an earlier government but with current government focusing on protective policies to enrich billionaires', it might take longer.

> This is not a non-compete issue; that's when the company tries to stop you from working for their competitor after you quit.

This is a non-compete issue. Because it's in CA, OP can quit the company right away and start a competing business (presumably the big tech company will start doing something similar) without worrying about non-complete. (This is not legal advice)
I agree with you on both points but when building large complex applications (or tools!) this stuff tends to unintentionally creep up over time and it’s not fun to debug non-deterministic bugs due to an opaquely broken implicit contract between you and a poorly written library that got pulled in transitively. Sometimes those libraries are unavoidable closed source system libraries (https://bugs.python.org/issue33725) and the issue ends up being not easily fixable. It’s just risk minimization.
Great to see some fellow Badgers aiming to make a dent in the universe. 3x higher power density is a huge leap, looking forward to watching you make it happen!
This is the reason people get frustrated, right here. Having expectations that a for-profit tech company doesn’t behave one. Why wouldn’t they use everything at their disposal to slam the competitors?

> forcing people to be born without their consent

How could someone consent to be born?
I think there's two issues.

The first is that I recall the shower curtain problem was related to the heat / steam floating around in the shower which facilitated shedding of particles and also ingestion. Having the "plastic" clothing just on the body may be less bad.

Also, and more importantly, I think people who are conscious about those things tend to wear less plastic fibers but won't necessarily think about the shower curtain.

For example, except for full on technical sportswear (think biking shorts), I never wear polyester or other synthetic fibers in clothing that goes directly on my skin. I used to avoid it because, for the most part, I've found that polyester is less breathable, tends to stick a lot, etc. I try as much as possible (I check the labels) to stick to cotton / linen (for the summer) / wool (for the winter). Now, the whole "plastics are bad" thing doesn't really push me to reevaluate my choice.
Yup, good for them but I do think that something that is fixable by a simple pump and that very few people practice (I know of know one who will change their pressures multiple times per ride) will catch on.
> I assume that you're putting "correct" in quotes because you disagree with the idea that this is correct.

It is in quotes because it conforms to some definition of "correct", which is rather ambiguous, and because hue isn't the only factor of complementary colors.

> While useful, it's clear that our understanding is very limited.

I respectfully disagree. (Though acknowledge that our understanding of color is not complete.) I assert that our understanding of the mathematics of harmonious color are well understood because the spectral relationships are fairly straightforward. It's not uniform, like auditory relationships, but at least narrow-frequency relationships follow pretty simple patterns once the perceptual space is compressed. (Thus 180 degrees being "correct" complementary.)

The problem arises in our computationally-efficient matrices/transfer functions which distort those relationships and introduce the lightness and chromacity. I acknowledge, however, that it's not quite as "firm" as I phrased it.

> ...the only reasonable way to teach people how to pick harmonious colors is to have real humans use their brains and sense of aesthetics.

I agree that it's way better than shifting an HSL/HSV hue 180 (or however many) degrees to find a harmonious color. It's way more complex than that, and a proper tutor is much more valuable than an erroneous color space representation.
It depends on your definition of “luxury”. I’d consider Tesla “luxury” like BMW is “luxury”, but a bit less refined and heavier on the technology.

There are lists available, e.g. https://edlists.org/

When the EU was debating the REACH regulations there was a big push to move to a "don't sell or produce it until you can prove it's safe" stance, but AFAIK it was significantly watered down before an agreement was reached.

https://ec.europa.eu/environment/chemicals/reach/reach_en.ht...

Then there's the problem of "chemical cocktails", where combinations of chemicals are more dangerous than each chemical by itself; this gets a lot of media space, but is even harder to research than individual chemicals since just about everything gets mixed up in various concentrations in nature.
Would it be... unreasonable... to point out that the fall in sperm quality, egg quality, and overall hormonal disruption is happening concurrent with a blurring of overall gender identification, predominantly in the youngest generation?

Identification as trans or other non-binary status is incredibly high among the gen-z cohort. Might be unrelated social upheaval, but would anyone really be surprised if we weren't accidentally hormonally poisoning children at the same time they are developing their own gender identities?

If there’s market value for news then news sellers should stop giving it away for free and starting charging a price.

I'm not sure I follow. Are you suggesting that we, as a society, should not invest in worst performers? How would we even know beforehand? And how would withdrawing such funding from "bad" schools not affect the opportunity of all of the children of that school?

> What about European countries with similar median wage to the US but where most people choose small cars? I think big cars in the US is partly a cultural thing, and also partly because roads in the US are bigger

While I agree with you overall, I have a small thing that, I feel, you forgot about.

While the median wages in European countries are the same, are they taxed at the same rate as their US counterparts? What about cars themselves, do they cost higher (MSRP+sales tax+fees+etc.)? And what about the cost of ownership (higher gasoline taxes+annual registration fees+etc.)?

Mind you, I don't own the actual information about most of those, those questions I posed weren't rhetorical. However, I have a gut feeling that median wage Europeans are taxed higher on their income than their US counterparts, and I know for a fact that some things when it comes to car ownership in Europe (like gasoline) are indeed noticeably more expensive.

P.S. I am not trying to start a flamewar about which approach to taxation and pricing of goods is preferable, I understand that Europeans might be getting more worth out of their taxes, even if they are being taxed more overall. There are pros/cons to both, but that's not what this conversation is about, so please don't take my comment as trying to take a stand on that debate.

Glad to see more people working in this space. Hopefully you will be able to treat food allergies in a similar way, e.g. working up the milk ladder with a set course of pills.

My son was born with multiple food allergies, and whilst he has outgrown some, the current approach here is 'wait and hope they grow out of it' or 'try introducing the allergens very gradually so that the immune system learns to not react to the allergen').

One suggestion - state what allergies you can currently treat above the fold. I shouldn't need to scroll down to learn it is only for pollen, pet, and dust allergies. Best of luck!
The point of that movement is to restore balance to earth, but what’s the value in doing so if no one is around to appreciate it? There’s really no difference one way or the other; it’s just a sphere in the universe.
Purely anecdotal, but modern Porsches that is not a coupe (defined as having 2 doors) have shown horrible reliability of onboard electronics. Not that Tesla is a lot better either (MCU black-screen-of-death comes to mind), but yeah, YMMV.

I do agree that Supercharger matters a lot more than its "sticker price" and all the drama on various incentives. Turns out it did compensate (somewhat) early adopters for the, uh, rather brutal depreciation not completely anticipated by all, and is a huge enabler for even the not-so-long-ranged variants.
I’d be hesitant to call the issue preventing simply closing up for a few weeks (which I agree should have happened) “lockdown deniers”. We’re had mass protests and riots by the same people apparently for the lockdowns and the more recent scandals with politicians of all stripes caught breaking their own restrictions on indoor dining, not wearing masks, or breaking travel recommendations to fly to vacation homes. The problem there’s a myriad of problems, the most original likely being that covid got politicized in the first place.
I will bribe people to put wrong information on the blockchain then.
> goods like iPhones, vaccines, pharma products

May be look into more details of it's supply chain and you will notice all of these completely depend on China, Korea, Japan and Taiwan imports. Also most of them are low end production. Pharma is a bright spot in India given the patent policies promulgated in India during earlier government resulting in innovation in formulations, but here also India depends heavily on API (Active product ingredient) imports from China.

As I mentioned China only recently became better in last 10 years after 3 decades of continuous assembly and production improvements, India did well under earlier government, but as mentioned in earlier comment protectionist policies of current government whose policies benefit the rich in India, will slow down that process.
What's your definition of cause here? Human agency? In that case, people could have decided to donate part of their salaries to businesses they previously frequented,or other rediculous "choices" that humans would never do.

I don't think there is a coherent notion of cause and effect where both covid does not cause the recession and the lockdown does. I can see very restricted notions of cause and effect where neither "cause" it, and more normak notions where both cause it, but not one where one causes but not the other.

And that's ignoring the absolutely rediculous premise that the covid death toll and long term disability toll has no effect on the economic downturn and it was purely caused by the lockdown. There are reasonable arguments that lockdown has been a net positive for the economy in the long run (even more so for non-usa countries that did it competently)

> Please, just don't do it. Yes, I read the dissertation. It's just not a good idea, it has never given me any practical use whatsoever and has always made dealing with the API more annoying.

If you believe REST is not a good idea then you never had to deal with versioning and struggling to keep clients and servers you don't own to play nice. Asserting that something like REST has no practical purpose is asserting that your experience is slim to none in this domain so that you are not mindful of the most basic challenges of getting servers and clients that evolve independently to continue to interoperate with minimal development effort. REST is content discovery and allowing clients to transparently adapt to breaking changes in the server. How does anyone with any relevant experience miss the point of that?

Furthermore, your assertion makes no sense at all. The main property, and the whole point, of REST is HATEOAS. It makes absolutely no sense to claim an API is REST if it misses the single most important design element that's behind REST. This is not pedantry or nit-picking: it's the whole difference between plain old RPC and REST. If you want to design an API that provides fixed endpoints to be called,and isn't discoverable or navigable, then just call the spade a spade: RPC over HTTP. Otherwise why do you feel the need to claim you design an API around a design principle you don't use and even criticize?
