Uh, some motor controls questions...

What per-unit impedance are you targeting for the stator winding?

Does the motor controller need an LC output filter to keep the motor's high-frequency current reasonable (thus forming an LCL with the stator winding), or is the stator winding inductance sufficient on its own?

What techniques did you employ to get a wide speed range? Is it an interior permanent magnet machine, surface-mount permanent magnet machine, etc...

Does the controller have a common-mode filter of any sort to cut down on the common-mode bearing current?

Are you building off of 1200V SiC 'FETs or 1700V?

* a UI change to check the box this information is on

* UI change to view whether the box is already checked or not

* a data model change to store the information

* business logic change that modifies some critical code that calculates when someone should be released

* security/access control change to decide who is allowed to check this box

* auditing logic to keep logs of this stuff

* possibly new UI/management code to add/remove members to this group of people who can check the box

* together with adding some procedures for tracking who completes what, documentation, training and auditing.

* Testing the whole thing.

Probably for piles of who knows what where the original author is long gone and the test code is no longer functional.

If you reach the threshold required to get into YC, then your location and experience won't matter (and with the size of the batches getting larger and larger, you could argue that it is in fact getting easier to raise money now than before).

If something about your seed-stage startup is stopping you from getting into YC, then I would ask myself if I might be doing something wrong. This is coming from someone who went through YC with one startup and also got rejected in another instance. While YC does make mistakes, in my case they were spot on.

> Maximizing profit is not always the best way to go.

My comment was not advocating for 'maximizing profit' - secondary markets do not make for happy customers, nor do excessively long wait times. Yes - a waiting list can be part of a luxury good, but there's probably an optimization of customer happiness somewhere shorter than a 2 year wait list.

A wait list that excessive can spur a secondary market, which makes the wit list even longer, which makes customers and potential customers that much less happy. And the secondary market only enriches the middle-man, while doing nothing for your loyal fans and customers.

I think it's pretty likely that the person (or people) who went by Satoshi is dead, and probably died before their Bitcoin hoard was worth much.

If not, you'd have to explain why someone is giving up the opportunity to never have to work for someone else to support themselves ever again. And those are less believable to me: e.g. 1) already having so much FU money they're secure in their lifestyle w/o the Bitcoin, 2) being either extremely ascetic or happy to work for someone else to support themselves, 3) deliberately choosing to destroy it for some reason, 4) losing the all keys in an accident (more understandable for a rando playing around than the creator), etc.

One of the things we've lost with the decline of newspapers is investigating and publicizing things like this.

Locally, the city decided to disconnect its open air reservoirs and replace them with reservoirs underground. It's a huge construction project and there are supposed to be close relationships between the water bureau and the prime contractor. Close as the #2 at the water bureau being married to a VP at the contractor. People retiring from the bureau and going to work for the company. And so on.

The city, county, and state legally have to publish notices in a paper that meets certain standards. If the city doesn't like its coverage, it can move its advertising. This probably didn't matter 20 years ago but newspaper want/need every cent they can get.

> high minimum wage (up to 25$/hr in some areas)

"some areas" is doing a lot of heavy lifting in this sentence of yours. First of all, there is no Federal minimum wage, it is Cantonal. Second of all, the minimum wage of 20CHF only exists in 2 Cantons: Jura and Neuchatel. Third of all, once you PPP adjust that number, it's equivalent to about $10 USD/hour.

> It's vital to recognize that criminals can choose to exit the criminal class.

Citation needed.

How can one choose to not have a cop plant evidence on you? Or lie during trial, or choose to not get strong armed into pleading guilty because you can't afford bail and they're threatening you with even worse consequences if you don't plead out early? Or not have a law about drug usage enforced selectively against you and not against others? These are things that happen each and every day in this country, to paint that as a choice on the part of everyone is actually kind of insulting.

Even for those who did commit crimes and got thrown in jail, what exactly do you expect them to do when they get out and can't get a job? Recidivism is very high in this country, higher than our peers. Either you've got to conjure up something about American criminals that makes them permanently criminally, in which case I will just assume that you're two steps away from getting out the skull calipers, or you're forced to come to the conclusion that we've decided to arrange our society in a way that makes this a likely outcome.

Yes, some individuals do escape the cycle, and that is both good for them and good for society. But given the strong trend, one has to ask why.

> stay addicted to drugs, sex, and violence, and keep coming to prison over and over

See, there's a funny thing that happens here. This logic is only ever applied to some people. Poor, black, and addicted to crack? Criminal, straight to jail, do not pass go, do not collect any help. Rural white and addicted to opioids? Well by god they're a victim who needs help!

Now to be honest, I think that both of those groups need help, and should be treated far, far better. But the selective nature of who gets sympathy and treatment and who gets steel bracelets is pretty core to my argument.

> There are some skinheads that blame racial preferences for their own failures in life, lest anyone think that I'm naming SJWs facetiously

I still think you're bringing up SJWs facetiously.

> Stop telling people that they have no control over their lives.

Stop making up my point. It's annoying.

Every single person's outcome is a mixture of their own choices, luck, and society. Individual choices matter, I never claimed to the contrary. The question is not "do individual choices matter" but rather "is the playing field setup in such a way that some people's choices are more likely to result in negative outcomes than other people's?"

> in the early 90s 55% of US whites were opposed to interracial marriage

In the early 90s, roughly 80% of whites were opposed to laws against interracial marriage, but a larger share thought “disapproved” of it. Was that racism, or an assessment of it's viability based on life experience of older adults growing up a society where racism had always been prevalent? A hint might be that it wasn't until the mid-1990s that Black support for interracial marriage started climbing from where it had been since the 1970s. [0][1]

> . In 1990 David Duke came dangerously close to becoming a US senator (after serving four years as a representative) and in 1992 was still very powerful in LA politics.

And in 2000 his superior performance with his appeal to his white supremacist base was explicitly cited by Donald J. Trump when he dropped his bid for the Reform Party nomination—before reinventing himself politically and coming back 16-years later using the same tactics and appeal to the same ideals to win first a major party nomination and then the Presidency.

Whites in America seem to think that racism continued being less of a problem over time through to today, but for blacks, in a number of areas, that perception increased starting in the late 1990s. [2]

> The country has really become dramatically more progressive since then (despite the Republicans specifically becoming more reactionary on the whole).

I think that's arguably true, but only in a way consistent with my description earlier: it is much more that (a significant subset of) the not-racist segment has become much more actively anti-racist than that the country has become less racist. This has also resulted in racial issues being much more polarizing.

> America still leads the world in one thing: inflating speculative bubbles using gibberish finance acronyms

In my experience, in the rest of the world people from all walks of life get caught up in the even greater gibberish financial terms for financial products that don't even exist in the described form.

In the commodities space it is at its peak.

The biggest offender is the "SBLC", which in reality is simply where a bank acts as a guarantor and underwriter, but in the joker broker network (aka 99% of the commodities sector), an SBLC is a freely tradable security that can be used in lieu of cash. There are people that think they have received these unicorn SBLCs (pieces of paper and forgeries of bank letter heads) and simply haven't tried to deposit them yet. And there are orders of magnitude of more people that think they are engaged in the trade of SBLCs or that they exist in this form. The real existence of the term makes it harder to cut through the disinformation.

Interesting. Can you give a rough estimate of how much effort has been put into studying it (wall time, researcher-years, money) and how much progress has been made?

> No, it's not. It's “essential workers”, which....

Not to be impolite, but _I am absolutely correct_.

See here [0] for the detail, on which I quote, "in Phase 1c, persons aged 65–74 years, persons aged 16–64 years with high-risk medical conditions, and essential workers not recommended for vaccination in Phase 1b should be offered vaccine."

Further, if you read the double asterisks note at the bottom of that page, you'll see this, "On December 20, 2020, ACIP voted 13 to 1 in favor of the Phase 1b and 1c allocation recommendations."

Finally, if you look at the chart on the lower half of the page, you will see that _group 1c includes 199 million people_ (32 + 110 + 57 ), which is, after the 75 million people in groups 1a & 1b, darn near everyone.

So if you think I'm wrong, offer proof, not an interpretation. With proof, I'll gladly admit error, but the facts are very clear.

So this is how you justify it to yourself? Honest question. It seems you acknowledge the legitimacy and urgency of the problem but are unwilling to make changes due to it being social suicide?

This is kind of where I feel I am, so I'm curious for you to expand. Do you have kids? Will you be able to tell them you did something positive about this problem? Or greedily stayed complicit due to the inconvenience? Are you prepared to tell your daughter you were the part of the people killing all the wildlife on earth? I know that sounds super aggressive but I'm legitimately asking. This stuff goes through my head for myself, so I'm curious how you address it?
That does seems like kind of a strange thing to say. Raptors may not sit in the native trees but they certainly depend on the food chain below them that needs the natives.

Doug Tallamy's Bringing Nature Home makes a convincing case for the importance of native plants to healthy ecosystems. (Hint: it's the insects.)

The significant environmental factor is that many planes have been sitting idle for months. This is exceptionally unusual in the life of most airframes. Idle time is an opportunity for parts or fluids to settle in a way they might not otherwise.

For example an extremely slow fluid leak could be “reset” every time the engine is operated. Allow time for fluid to accumulate and suddenly there’s enough fluid where it shouldn’t be, perhaps causing just enough mechanical stress to exacerbate an previously unknown wear point or design flaw present in a tiny minority of copies.

(Of course this hypothetical flaw couldn’t cause catastrophe on first flight, as that is generally an empty plane travelling from long term storage back to the airline’s hub airport. The flaw would have to subtly weaken a part which then fails after multiple rounds of uneventful flights.)
"Another [Boeing's (if you insist)] Pratt and Whitney Engine ..." would be a better title, Boeing has little to nothing to do with the engine, and Pratt and Whitney engines are found on Airbus aircraft too.
Meh. SPACs have a pretty simple purpose: allowing companies to IPO without it officially being an IPO (eg much less disclosure for example).

For the companies they can avoid the risk of the IPO. If wework had gone public via SPAC they would have actually gone public (although wework looked pretty bullshit even before everyone stopped wanting so much office space) and not just been a big embarrassment. I think it’s also popular for VCs to not like IPOs at the moment (if the price goes down that’s bad. If the price goes up they’ve been ripped off in the investment they got. At the moment it seems newly public stock is in high demand so every IPO feels like a rip-off.) Maybe they like SPACs better.

For investors a SPAC exposes them to the IPO pop: like the investors in an IPO, the SPAC reduces the risk of going public to the company and they expect to get paid for that by getting stock slightly cheaper than they expect; but those investors also get optionality when the deal is announced. Ordinarily small investors wouldn’t get the chance to participate in IPOs.

For the managers they get massive payouts, even bigger than investment banks get for IPOs. Maybe those will go down if SPACs become popular and mature and competitive. (Though note that there are some incentives for managers to get a good deal.) And probably there are lots of people enjoying and getting money out of trying to figure out how to price shares in SPACs and the warrants, especially while there is a lot of variety.

Maybe you think SPACs are great or maybe you think they’re cheating regulations or siphoning off money to rich bankers or random celebrities and should be made illegal. There are some economic reasons to expect a SPAC share to be worth more than the investment it corresponds to, and there are social reasons to be wary of SPACs. I don’t think the article does a great job of discussing either.
It's mostly not been great. Higher prices than national DOE prices, less prepared for extreme events, and notably, no power-sharing agreement possible with the national grid since they've explicitly opted-out, and vehemently defended that choice. The Texas grid is less reliable and more expensive than either US East or US West.
Yes exactly, its exactly the reasons you said, high risk and few assets.

> creditors bearing the risk of default.
The person giving away the money is always bearing the risk, that doesn't go away. VC will bear the risk still.
Refers to a problem where the pilot did the wrong thing because of disorientation or perceptual confusion.

Take controlled flight into terrain, a common enough problem that aviation safety writing just calls it CFIT. This is when an aircraft collides with terrain, but there was no loss of control. CFIT is a relatively common occurrence, but why does someone fly a completely controllable aircraft into the ground? Almost always due to perceptual confusion, disorientation either to attitude or location. Unintended entry into instrument conditions (e.g. into a cloud or fog bank) is one cause, but disorientation can occur for a number of other reasons as well, including in good weather conditions.

As in if you go 10meters underwater your orifices experience 1atm of pressure difference. In the reverse to space but the point being you can handle this just fine.

There's a myth that at low atm of pressures you pop and such. This is not true. You may need to breathe in/out to adjust but pretty much every part of the body can handle 1atm of pressure difference just fine. The 10meters below was intended as a reverse example but the point holds.
