You're right, some other entrants in the eVTOL community seem to have strategies that rely on some kind of regulatory magic. The company I'm working for, Beta, is taking a very different strategic approach, with much less reliance on "then some regulatory magic happens;" we are focusing on cargo first, and a passenger variant later. We are not particularly concerned with the change to 21.17b, we're willing to work with the FAA on that rather than fighting it. And because our initial target is cargo, such as transporting organs between hospitals with existing helipad infrastructure or cargo from airport to distribution center, there are a lot fewer regulatory hurdles about where we operate than the air taxi market.

We are following ARP4754A and 4761, yes. We are still in the process of doing our safety assessments at the aircraft and systems levels and finalizing our type certified design, so I can't say which systems are going to be required to be DAL-A, but I expect that the pilot inputs, flight controller, battery systems, high voltage distribution system, low voltage distribution system, lift motors, and control surface servos will be designed to that level. Our strategy is to build ourselves the critical components for an electric aircraft, so we are doing the battery, high voltage distribution, and electric motors, while we are buying the other components (pilot inputs, flight control computer, control surface servos, primary flight displays, etc) from existing suppliers who already have experience in this space.

In the meantime, we are also learning a lot from flight test of our experimental proof-of-concept airframes, which we can feed into this process. We've already built one experimental eVTOL under a previous design, and then two proof of concept airframes with a design much closer to the type certified design that we're now working on; so while we go through the process of breaking down the requirements per 4754A and doing safety assessments per 4761 and working on our final type certified design, we're also learning a lot about operational concerns and refining our design on our experimental proof of concept airframes.

As for the V22 line, well, our aircraft can't autorotate, but it's not bad as a glider. That was a primary design criterion; it should mostly be a glider that happens to have electric power. We recently did a cross-country trip halfway across the country on our PoC aircraft in CTOL configuration (https://evtol.news/news/beta-alia-250-prototype-flies-cross-...), with a number of stops on the way, of course, our range is limited by physics, and the majority of that trip was done such that there was an airport within the glide cone of our aircraft; we did allow for a few legs in which that wasn't always the case, and we would need to ditch in the event of power failure, but for most of the trip there was an airport within our glide cone if we had a power off event.
Does this person have any other rentals? Sound like a good deal for the renter to have a landlord that doesn’t care if they pay rent.
Not going to take a train when I can take a plane (which is not crazy expensive anyway). And as you know, planes are pretty polluting.

So not sure that ditching driving to your destination is a positive evolution.

Gold itself is just another fiat currency, with the only advantage being that almost every society known to mankind has somehow evolved to accept gold as the one and only "true value" storage. Only 10% of the world's gold production goes to industrial usage (mostly electroplating of connectors), the rest off to plain investment and jewelry.

Yes, depegging is an instantaneous event that happens when Tether fail to redeem a Tether at "face value". As long as they continue to do that, the value of Tether on an open market is only relevant in that it expresses the concerns of traders that they will eventually depeg.

Obviously as the price drops it becomes increasingly profitable to buy on the open market and sell back to Tether, depleting their fiat reserves and bringing closer the moment when they stop exchanging at face value, and it all ends.

Everyone is asking "why does it need to be so expensive"? I think it's basically the same reason why anything that doesn't have to be expensive, is:

1) To make money

2) To elevate status

For 1), buying world championship chess sets is not something done en-masse. You buy one because you really like chess and have disposable income, otherwise there is literally no reason not to buy a normal cheap one.

For 2), you don't want people to say the chess championship gives you shitty chess pieces that break, no? 95% of people won't care, but those that will will. And 500 dollars is not very much for an event this size (although chess championships haven't been the biggest event..)

The fact that they made a video showing off "look how expensive and nicely done our chess sets are" basically proves it's a status thing.
The CCS connector equivalent is relying on the onboard DC-AC converter for V2L-V2G, hence no inverter needed.

The CCS cable uses a resistor between PE and PP pin to allow the EVSE to determine its current capacity, 1–2.7kΩ for single-phase 13A all the way down to 50–150Ω for three-phase 63A. [1]

What manufacturers have done is tap into that and use some resistance to tell the car to go to V2L mode.

- Hyundai IONIQ5 and Kia EV6 use 50-75Ω for its V2L adapter, offering 3.6kW load

- MG ZS uses 470Ω offering 2.2kW load

- Ford F-150 to offer 9.6kW load, but resistor is unknown

- BYD vehicles to offer 2.2kW load but resistor is unknown

Actually I reckon it will depend on the countryside having alternative infrastructure. That's where things like range and charger availability really is critical. Cities already have public transport.
> I really don't see how a regulatory system could be implemented

I think that may be more a failure of imagination than a likely failure of the regulatory environment.

For example, cash transactions are largely anonymous. Financial regulation seems to cope ok by focusing on the points it interacts with the rest of the financial system and controlling it in the large. I can easily imagine it doing the same with the likes of Monero if it so desired.
If I follow the analogy right, the value of your debt is -8.6%.

The path to beating inflation is (a) borrowing at fixed low rates before it kicks in & (b) buying some asset that appreciates at greater than inflation rates (or at least paces it).

USDC by Circle, holds only cash and US government bonds. They are considered the safest stable coin. They are on-shore in the U.S. and registered as a money transmitter. They do get frequent audits but that being said USDC itself is not FDIC insured, so there's still higher risk than a bank account.

https://www.circle.com/en/usdc

Then there are truly collateralized stable coins, like DAI, which work off an automated system of collateralized on-chain deposits. DAI is borrowed into existence up to a limit. If a borrower's collateral gets within a threshold of going under water (depending on collateral risk params, could be 150%), they can get liquidated and their assets are sold to cover their debt. DAI is the most established of the "decentralized" stable coins. It was formed in 2017 by MakerDAO. All CDPs are on chain, and auditable.

https://daistats.com/#/

USDD literally launched within the past 60 days, right about when UST was going bust. These coins are algo ponzis that are not fully backed and promise exorbitant interest rates which are completely unsustainable.

Limiting the growth of an economy (i.e. construction of houses, loans to new businesses) because not enough gold has been mined is silly.
No, USDC doesn't get audits, and they stopped publishing their reserve breakdown in their attestations; compare September 2021 (page four) as an example against the more recent ones.

Same trick Tether pulled for years.

> However, the very next day, on November 2, 2018, Tether began to transfer funds out of its account, ultimately moving hundreds of millions of dollars from Tether’s bank accounts to Bitfinex’s accounts. And so, as of November 2, 2018 — one day after their latest ‘verification’ — tethers were again no longer backed one-to-one by U.S. dollars in a Tether bank account.

That's not necessarily true based on your link. Given Tether is invested in interest bearing instruments, the pool of capital should be move than the total outstanding Tether value. So even losing some by MTM at lower prices, they have a safety buffer...

Whatever you buy, you better save up for a new battery.

That's an issue with electric cars that has not really been solved, afaik. Most batteries will become useless at a rate that is not comparable to critical ICE engine parts, and they continue to be very expensive.
Yes, I get it, it's indeed a lot of surplus in the summer.

Long term storage would be the better solution, but batteries don't seems to be able to store a large amount of energy anyway. So in my opinion, it's really a tradeoff.

Maybe mine some bitcoins during summer? ;)
Their transparency page also states they have 1:1 asset backings which is a lie so oh well.

This page is irrelevant. They are not obligated to redeem your tokens. They're not liabilities. They may pretend they are, but they're not, and if the money stops flowing, they can leave with all the remaining money in the bank laughing at their idiot customers.
I absolutely understand the appeal of ic cars, and (I assume), everyone will still be able to hear an engine roar at a race track or other private space.

Engines roaring in a city might be nice for some, but for most it's just noise pollution, particularly offensive noise pollution at that. The lack of noise will be a huge benefit to electric cars.
> I'm pretty sure you're misinterpreting it

You should be more sure of the things you're pretty sure of before saying you're sure of them.

There was no misinterpretation—from this end, that is. Your comment wasn't particularly sophisticated. It didn't require explanation.

No shit. The value proposition of the semantic web follows from how the world would be much better off if that weren't necessary. It has always been the case that, without the "semantic" half of "semantic web", attaining Google-level mastery over the Web's messy inputs is really, really difficult and requires Google-level resources. This isn't news. Yet you presented it as if it were in insightful observation wrapped in sage wisdom.

In your attempt to "prove" by counterexample what's Wrong with the semantic web, you just end up undergirding its very premise.

> Which is why it is bizarrely unselfaware when Semantic Web advocates almost inevitably cite that as their biggest success.

You cited them. You are literally the only person who mentioned them here, at all. You brought them up.

Saddling someone who advocates for X with the burden of defending position Y that you yourself have pulled from thin air is a textbook example of a bad argument. If you defeat some easily take-downable opponent (a 6-year-old, let's say—and one who is made of straw, for good measure) and then plan to enter the ring in subsequent matches having only bothered yourself with the thought that you will face the threat of another strawchild, that's not wise. It's stupid.
I mean sure, $500 may be expensive for many players at home, but it hardly breaks the budget for a top championship that centers around said board for hours.

It depends upon where you think the money is going. If you believe people are parking their assets in USDT, then yes, you'd expect there to be upward pressure on the price of tether.

If instead, people are getting out of crypto altogether, they won't be holding USDT, instead they will be getting hold of actual dollars (which, depending upon the coins, might involve selling a random coin for USDT and then trading that for USD). In that case, there would be selling pressure on USDT.
Now let's look at market cap. Redemption is no longer "looked at" but in progress.

They way I look at it they are more like FIFA World Cup balls each year slightly different and for the last 50 years made by Adidas. Except there it's much clearer that they have little meaning outside the specific tournament games and value in sales outside it is clearly seen as collection item not as tool for performing the sport. There is no impression that those are only balls which could be used for proper football competition.

From what I understood by reading "Standards of Chess Equipment, venue for FIDE Tournaments" Even official FIDE registered games could happen with other chess sets as long as they are approved by Chief Organiser and the Chief Arbiter of the tournament and comply with much weaker and vaguely defined requirements listed in that document. Although I wouldn't be surprised if many organizers due to prestige and to avoid any unnecessary complaints from players would still try to buy the official sets.
> Right now, when you can buy a tether at $0.997 and (in theory) sell it back to tether at $1

No, you can't. Not even in theory. You have no right to redeem. They can choose to buy it back from you for $1, but it's not a right of the token.
Both are also essentially diffusion surfaces for transfering vital substances into (and in the case of lungs, also out of) the body.

Also germany needs some cheap labor but manufacturing isn't the main part, manufacturing is actually quiet expensive due to strong unions in germany especially in car manufacturing etc.

Banks running out of money and just failing outright leaving their customers high and dry for one. In addition to this, the scams, the lack of any consumer protection. The hype bubbles, the sheer amount of personal faith that is required to have confidence etc etc.

Why does tether not “buy back” all of those coins that it would be a loss to redeem? It seems like that would drive up the price and reduce their reserves by less than the alternative.

Bitcoin at 12k in 2017? Really?

You should welcome all the nay saying here if you think Bitcoin is bound to go up again.
There is not one single definition of safe, as perfect safety does not exist. So Java being 'safe' depends on the definition

Apart from the integer overflows the other three are IMHO reasonable, not surprising, known to everyone, and manageable.

* Data races: no, the Java compiler will not try to construct a proof of data-race-free behavior. Instead there are some tools: immutability, java.util.concurrent.*, lock checkers libraries [1] if you want something a la rust, actors, execution pools, futures, atomics.

* Null safety: Some annotations can deal with that.

* Named arguments: IDEs (IntelliJ does) now show parameter names of the method to the programmer.

All in all, the arguments presented are weak IMHO and Java is pretty safe, and offers pretty good performance with this safety definition.

As for data leaks, I'll steal a comment from Lemire's site: “Memory leaks are memory safe in Rust”

Yes, today there are roughly 1.1 housing units per household, which is exactly in line and consistent with history. This is also trending up, as population growth slows and rate of building increases

Shortage narrative is propagated by people who don't look at the data
This sounds fairly obviously fake. 128 cores at a TDP of 950W means only ~7.4W per core, which would be a massive improvement on the i9-9990XE - which can only do 5Ghz - and requires 18.4W per core. A tiny, hitherto unknown company with only a handful of engineers managing to outperform Intel by this huge of a margin strains credulity past breaking point.

They also talk about air-cooling four of the 600W model in a 2U chassis! I'm not convinced how possible it is to handle 600W for any reasonable socket size with air cooling at all - the watts per mm2 ratios are going to be very high - but the idea that you can air-cool 2.4kW from the CPUs alone (and at these speeds there are going to be a lot of other very warm components in there) in a 2U chassis is simply crazy.
