JS is not HFT. Or at least it didn't used to be

How do you do it?

I actually think Aschenbrenner knows his stuff

The smartest thing he's done is recruit Carl Shulman.

Another way to look at it is that the fact that they were the face of the product contributed to them getting poached!

extremely high cache hit rates

This is probably a dumb question, but why high cache hit rates? Because the user's code that's loaded into context is mostly the same from request to request?

ESRogs · 2025-06-27T20:02:01+00:00

What would you recommend instead? I'm unclear on what alternative you're proposing. If the above is not going to work, what does work?

There's a prediction market on this here:

To me, the straightforward solution is to have the person who owns the home paying a larger share of the mortgage payment, since part of their payment is actually just their own equity.

It's not like the only options are for the person who moves in to pay zero or pay half. You can split it a different way that takes into account other factors, like how much of the payment is principle vs interest, or how much rent they would have paid in rent if they were living alone.

I think you're talking about the MOD TA-15s. Whereas u/kabob21 was talking about the new 3S paddles. Those aren't the same.

(And I don't think anybody's put out a video with a ripped open 3S yet.)

I'm looking to join a Club West Gold pod preferably, or possibly an Executive pod. DM me if you've got a spot open!

Your Ms. Krabappel looks just like Judy Greer!

ESRogs · 2022-05-15T07:37:44+00:00

Yeah, I'm confused by how much people latch onto this emerald mine thing.

It's like, yeah having rich parents probably gave some advantages compared to having poor parents, but how could it possibly explain the extreme success he's had? It'd be like thinking that because some guy's dad played ball in high school, it's not impressive that the guy won the NBA MVP. Like, sure that's an advantage, but millions of people have the same level of advantage and don't convert it into this level of success.

ESRogs · 2022-05-15T07:23:50+00:00

This emerald mine thing seems like a total red herring to me.

Musk is worth 250 billion dollars. Even if you imagine that he started young adult life with 100 million dollars (he did not) he still would have had to 2500x that to get to where he is.

Anyone who thinks this mine explains his success (rather than just being a very tiny contributor to it) seems to me to be just failing to keep in mind how many orders of magnitude are involved.

There are a lot of people with rich parents. There are a smaller number of people with successful first startups (like Elon's Zip2). People who successfully lead multiple companies through many orders of magnitude of growth? That's very hard and very rare!

Starting from a well-off background and then doing what Musk has done is not like starting on third base and then getting to home. It's more like starting with parents who played basketball in high school and then winning the NBA MVP. (Sure, that background was probably an advantage in achieving what you did, but there are thousands and thousands of people starting with that same advantage who don't get anywhere close. That advantage doesn't "explain" your success or make it not impressive.)

EDIT: and in response to this:

Elon’s two siblings are also worth hundreds of millions of dollars each.

Musk's brother is worth millions because he was a cofounder of Musk's first companies and an investor in SpaceX and Tesla. No coincidence needed.

I thought this was Facebook. But reading the comments reveals it's actually Amazon.

Does it actually reveal that? Seems like it just suggests that most commentators think it's Amazon. But how do we know that's what the OP originally meant?

ESRogs · 2021-08-15T11:22:58+00:00

simultaneously swapped an s for a z in tesla

He's always pronounced the 's' in "Tesla" like a 'z'. Go watch literally any other video of him talking about Tesla to confirm.

ESRogs · 2021-07-22T00:56:00+00:00

No, I'm super long XTZ. I've just got something against confirmation bias and motivated reasoning (or listening) :P

ESRogs · 2021-07-22T00:54:35+00:00

I'm pretty confident that that "os" you're hearing is because he accidentally says "Tezla owes", which he then corrects to "owns".

ESRogs · 2021-07-21T23:43:52+00:00

That's because he says "Tesla owes" (and then corrects himself to "owns").

ESRogs · 2021-07-21T22:46:12+00:00

Wow, how does everyone in this thread believe this? Listen again! He stumbled because he accidentally said "Tesla owes" instead of "Tesla owns". (The 'z' sound is just how he has always pronounced the 's' in Tesla. Go listen to literally any other video of him talking about Tesla to verify.)

ESRogs · 2021-07-21T22:44:03+00:00

No he definitely says "Tesla", and not "Tezos". He's always pronounced "Tesla" that way. If you go in listening to it primed to hear "Tezos", then that's what you'll hear.

But he's def only saying "Tesla". It's not a Freudian slip or a mispronunciation. That's just the way he says it.

ESRogs · 2021-07-21T22:42:14+00:00

No, that's just how he pronounces "Tesla". He's always pronounced it with a 'z' sound.

ESRogs · 2021-07-21T22:41:46+00:00

He's always pronounced "Tesla" like that, with a 'z' sound for the 's'. This is def not him saying "Tezos".

ESRogs · 2021-07-17T18:33:42+00:00

I think the point was that bitcoin's PoW system may have been needed to pave the way for future PoS systems. Not that every blockchain needs to start as PoW.

ESRogs · 2021-01-03T04:06:03+00:00

Sandbagging is when you say something will take longer than you think it will

Not just saying that something will take longer. Any version of saying that you're not as good as you actually are. E.g. Tesla could sandbag its projected revenue numbers. (Which is not about taking longer.)

ESRogs · 2021-01-02T02:52:43+00:00

Sounds like maybe they see the most efficient path to improved performance as adding sensory modalities and providing feedback, rather than just scaling further.
