Former FTX US President Reportedly Quit After ‘Protracted Disagreement’ With Bankman-Fried - https://www.coindesk.com/business/2023/04/09/former-ftx-us-p...

> ...

> According to the report, another employee in the exchange’s legal department was “summarily terminated after expressing concerns about Alameda’s lack of corporate controls, capable leadership and risk management.”

> Alameda wasn’t even clear on what its own positions were, “let alone hedging or accounting for them,” Ray's document reads. A June 2022 portfolio summary, which was supposed to show Alameda’s makeup of crypto positions, was reportedly fabricated after employees were allegedly instructed by an unnamed higher-up to “come up with some numbers? Idk.”

> At one point, according to the report, Bankman-Fried told employees:

> “Alameda is unauditable. I don’t mean this in the sense of ‘a major accounting firm would have reservations about auditing it’; I mean this in the sense of ‘we are only able to ballpark what its balances are, let alone something like a comprehensive transaction history.’ We sometimes find $50m of assets lying around that we lost track of; such is life.”

I'm not sure "devious" is the right word choice. Criminal activity - yes. I suspect they knew they were criminals to some degree but were grossly incompetent when it came to managing it.

It feels more like a constant stream of lies to support the ongoing fraud rather than devious.

Sort of, though I'd say scan operations are typically more expensive in any RDMS.

The probably becomes when you want/need something more than the secondary index, then you gotta get more creative.
DynamoDB is amazing when you know all the access patterns for your data and the access patterns are not liable to change much. The performance it gives in such a case is superlative to just about anything else. But if you have changing access patterns and require flexibility in querying, then DynamoDB is not for you.
Thank you. The OP is from the authors of Hyena, and I agree it's unclear if it will scale as well as self-attention in transformers. The paper on RNNs looks very interesting. I like the fact that it keeps things simple and familiar. I've added it to my reading list.

I don't have any idea what that has to do with "socialized care." If anything, most of those factors resemble the way businesses scale up.

I live in SF, I’ve been seeing driverless cars in the Bay Area for 4 years, and recently I’ve started riding in them commercially because I’m opted into their public testing programs/commercial riding.

I don’t think they’ll have much trouble in Boston. The current Cruise service area includes a lot of steep hills, narrow roads with parking/pedestrians on each side, and some winding streets. Driverless cars are typically pretty cautious around hazards like this, sometimes a bit too much (like driving up to a stop sign too slowly), but matching what I would want a “safe driver” to do.

I took a Cruise in the rain a few days ago and the rain didn’t seem to cause any problems at all. Even though you can only take Cruise at night, between 9 and 12 pm there have still been plenty of situations where it had to deal with pedestrians walking across middle of streets, opening and closing doors of cars parked on the street, cars stopping in the middle of the road to unload pedestrians, etc. and it’s actually handled all of them well.

When the cars get stuck, I am pretty sure it’s because they are in “mapping mode”. I think it’s weird and likely unscaleable for an entire service area to need to be mapped before opened commercially, but once the cars are actually “working” they don’t get stuck much.

Anyway, I think the only real problem with Boston would be snow and ice (on the ground, I think the rains and fog in SF are close enough that cars could handle snow and ice in the air).As far as I know, no self driving car company has tested much under snowy/icy conditions.
That's actually what many formal tools excel at. Of course, you have to do have to define "never promised that behavior" which is extra work that nobody wants to do.
I think that OP implicitly assumes that new mothers are dying more due to systemic failures that apply to other patients too.
Yeah and it's super simple to roll significance and effect sizes in one with confidence (or credible) intervals.

Plus the interpretation is super straight forward: CI contains zero: Not significant. If nothing else, we should make CIs the primary default instead of p-values.

It was likely created in the same process that created other isotopes of Uranium (probably neutron star collisions) but didn't last very long.

Plutonium was long considered a "man-made element" and it mostly is but if you look carefully at natural uranium you will find occasionally a neutron hits a ²³⁸U atom and winds up making ²³⁹Pu but it doesn't last long so you find only the smallest traces of it.

The end state of socialism and communism is also "you'll own nothing and be happy". All political/economic systems suffer from corruption and abuse of power at the top. The only difference is the ability for the masses to control their own destiny. Market economies give them a little, control economies give them none.

Lol, no tigers don't generally attack people, and will often run away when the human stands up. Attacks on humans are generally similar to Bear attacks, defensive in nature when people are messing with their young or getting up in their business. Though there have been cases of injured tigers going nuts and switching to attacking people.

“Cecil the Lion” was not a tiger. "the elimination of a dangerous menace" no, he lived in a national park and was practically a zoo exhibit. He had a GPS tracker and all the safari tours in the area would go see him. His fame with tourist is what caused the uproar.

This is incredible. If I understand the thread, that >$22,000 surprise bill was not forgiven by Vercel and the most they're willing to do is offer a 25% discount.

Is Vercel a business or a scam masquerading as a tech company?

If a company needs to stoop to this level of billing shenanigans to make money, I have my doubts...
Think there is confusion here - if I understand correctly you are asking about the number generator, they are talking about the process of determining success. Like in league of legends you have a listed crit chance but the way they determine success isnt to generate a number and compare it to your chance, you start with a smaller base number that gets incremented each time you fail and reset when you succeed - the end result is that your overall chance remains the same but the likelihood oh a streak (of fails or successes) goes down.

Doesnt change the overall probability, drastically reduces variance.
This is spot on. Parts of Amplify are aimed at people just getting started with Cloud and Programming, which is good and bad. You can shoot yourself in the foot if you drive the car too fast. I think a lot of more advanced people use Amplify services along with the Amplify client SDKs and then do the provisioning using CDK rather than the Amplify CLI.

I think if hypothesis testing is understood properly, these objections don't have much teeth.

1. Typically we use p-values to construct confidence intervals, answering the concern about quantifying the effect size. (That is, the confidence interval is the collection of all values not rejected by the hypothesis test.)

2. P-values control type I error. Well-powered designs control type I and type II error. Good control of these errors is a kind of minimal requirement for a statistical procedure. Your example shows that we should perhaps consider more than just these aspects, but we should certainly be suspicious of any procedure that doesn't have good type I and II error control.

3. This is a problem with any kind of statistical modeling, and is not specific to p-values. All statistical techniques make assumptions that generally render them invalid when violated.
I don't know if you've ever been to a walkable city, but they pay for themselves. Because people don't spend all of their time driving to and from the place they want to be, they get to spend extra time shopping and growing local businesses that pay taxes for infrastructure to stick around.

Car lanes are paying money for people to skip those places and only go to one place at a time without drawing them to other places in the same area. If I'm driving to the store, I'm driving... To the store. I'm not going to walk around outside of the store after I'm done. This has no benefits for adjacent businesses.
I know you're being inflammatory to make a point, but calling this "fascistic" is really out of line and dilutes the concept.

> "Otherwise, since rent is still pretty affordable in predominantly black neighborhoods you would think they (white people) would choose to live there instead of moving outside of the city and having longer commutes and bigger mortgages."

This is one of the most blatant cases of selective omission I've ever seen. Pray tell why is rent in Detroit or Chicago so cheap? I mean I spent two years doing humanitarian work across north Ohio in some of the cities that have incredibly "low rent" there's a reason for that, and anyone who can chooses to leave when they can for very obvious reasons if you go and visit those areas.

> Auditors seem mainly to just double check the numbers they're handed. This serves a purpose, it provides some level of guarantee that companies that are acting in good faith are generally reporting correct numbers. Auditors don't do what people seem to think they should do - investigate and uncover fraud. If a company wants to commit fraud, the auditors simply aren't resourced in a way that would allow them to uncover it because there's not really that much incentive to uncover the fraud, the fraudster is extremely motivated, and if you wanted that level of hostile investigative work it would be much more expensive for every company.

While I agree audit is a hard job auditors should not just rubber stamp what the company gives them. They should ask probing questions like "where did this sale come from?", "how did you calculate this figure?" and "why are you doing this? It is unusual." A consequence of this is that they may pick up on suspicious signs within a set of accounts and choose not to sign them off, but I wouldn't say theeir job is to identify fraud per se.

What is clear from cases such as wirecard is that EY have failed to ask these probing questions on several occasions, and subsequent audits (by other firms) have shown it is entirely possible to ask appropriate questions and uncover dodgy practices.

> many EVs are simply off the table due to battery life concerns

What EVs would be off the table? The Leaf is notably bad in this regard, as you mention, because the battery is passively cooled. However, all the other EVs I'm aware of are actively cooled and should be fine in hot temps.

It's an earnest question—I don't know anything except as a consumer who's shopped around for an EV, and as a resident of a hot climate I'd be interested in knowing what I need to look out for.
They stitched 25 random amino acids together and then assess the resulting polymer for solubility and foldability. Solubility requirement is self explanatory, can't have life that is insoluble in water. Foldability is basically how likely for these polymers to entangle and collapse on itself. This is critical because protein folding depends on this process to generate highly compact and dense atomic machineries.

They find out stuff that are too soluble can't fold well because they prefer water over other amino acid. And that seems to exert a selection pressure, ending up with a specific set of amino acids that life depends on.
My impression is that there is a lot more auditing going on in the conventional financial system. Not to say that it's not bad, but there are at least some (legit) outside eyeballs on your system.
I think the point is that index holders lose money at every jump in and out event. You can't average a list of losses to make it zero.

For example, someone willing to pay a $1 premium for an indexed stock.

It is trading at $5 today and becomes indexed, so you pay $6 for it. It leaves the index so you can only sell it for $5.

It doesn't matter how many times you average it, it is still a source of loss.
Yeah, just saw that. Sorry for the noise.
Where the heck are they going to find feedstock? Renault found that the batteries don't wear out, they just keep running, going on 10 years.
Depends. If 90% of the traffic is still cars, bike lanes make it possible for the 10% that is bikes. But the 90% now have fewer lanes.

You sound like you're assuming that, given more bike lanes, 50% of the traffic will ditch their cars and ride bikes. (At least, your logic doesn't work without that assumption.) I don't think that's a valid assumption.
This didn’t age well
So habits are different from practice (I meant it in the sense of “application”, not so much in the sense of practicing the piano).

Habits refer to repetition, which implies you already know what to do so you’re just trying to get better at it. This works in closed domains where there is already a body of knowledge or pedagogy.

What I meant by practice is more about “applying” something — which means lots of experimentation to figure out what works. (In other words being a practitioner of ideas, rather than just a knower of them)

A lot of ideas that sound nice often fail when the rubber meets the road, which is why you have to subject them to the crucible of the real world through practice.
I would add a bit of my own experience.

Products like this are great. But if you already know the technology, know what is happening and you are using it to basically eliminate a bunch of coding or setup tasks that you would have to do.

The problem this is only great for a certain type of knowledgeable developer who is also setting up the system.

The next person that comes or a junior developer who does not have grasp of the underlying tech will just see a bunch of magic. But he will be required to be productive with it.

So if the original devs leave and don't get people with grasp of the underlying tech, the new people will start accumulating technical debt at an ever faster rate without ever being able to pay it back. Because with so little knowledge and expectation of performance, whenever something small happens that requires you to learn stuff you will skip learning and just move stuff around hoping some random change will fix it.

So I will amend my original statement:

"Products like this are great." But only if you are working on the project alone and don't expect anybody else to join it in the future.
We should at least be aware of it as an option. Many call this "healthy skepticism". It becomes unhealthy when you veer into blind optimism/pessimism/cynicism.

>False, everyone is not a Pedestrian, I moved into my current home specifically because there are no sidewalks (and no HOA), and I resist any movement to add them to my street.

What the fuck!? Why don't you want a sidewalk? Why would any street even be built without a sidewalk, like how is that even an option. How is anyone meant to walk safely?

Where are you from, Mars? Cause you may as well be speaking Martian, I can't comprehend your mindset at all.

How does anyone go for a morning run? Walk their dog? How do kids get to their friends' houses? Even in a low density suburb people do these things.

"The number of people who use sidewalks" is like ... 99%. Everyone uses them at least a little, unless you're literally bedridden or something. Or out in the middle of nowhere.
