I can’t believe the Chinese did this https://www.404media.co/henrico-virginia-datacenter-energy-c...

Big shoutout to this study! Highly recommend donating if you get any value from these lists

The latest helmets have a releasable layer that absorbs (converts rotational energy?) more impact.

MIPS? Or is there something newer

what if Claude Code was built for Wall Street?

Nah I think most people could make something like this in a weekend

Note that diffsitter isn’t abandoned or anything. I took a year off working and just started a new job so I’ve been busy. I’ve got a laundry list of stuff I want to do with this project that will get done (at some point)

I don’t think that’s true. C++ just has a lot of baggage to deal with and people are doing the best they can with some ridiculous constraints. The sanitizers and things like clang-tidy, and better analysis in compilers seem to be really well received.

I might have misinterpreted what you mean as “standard” (I was originally thinking like you meant that the standard dictates all operations must be safe and doing things like the unsafe/unchecked option references would be outside the standard). I realized that you might mean it like it should be the default behavior, so correct me if I’m wrong there.

Yeah I agree that sane defaults would be nice and that things like unchecked accesses should be more explicit. Having linear types to properly enforce issues with things like use-after-move would also be awesome. I don’t know that anyone has ever accused C++ of being particularly ergonomic. Sum types and pattern matching would be awesome.

Nothing wrong with being a Rust fanboy :), I have written some (https://github.com/afnanenayet/diffsitter).

Works for whom?

FAANG, hedge funds/HFT, game studios

but why not just enforce that as standard

I don’t think people want that as standard. The whole point of using C++ tends to be because you can do whatever you need to for the sake of performance. The language is also heavily driven by firms that need extreme performance (because otherwise why not use a higher level language)

There are knobs like stdlib assertions and ubsan, but that’s opt-in because there’s a cost to it. Part of it is also the commitment to backwards compatibility and code that compiled before should generally compile now (though there are exceptions to that unofficial rule).

Gambling is much less regulated than the markets.

I don’t think the last two decades of computer graphics research are an Nvidia psyop. Ray tracing is relatively simple and also reflects reality (you’re literally doing a light simulation to approximate how we really see). It’s always been the gold standard for rendering, we just didn’t know how to make it fast enough for real time rendering.

Was the US still your favorite during the Bush administration?

I don’t think it has to be that crazy. I only have a Bachelors in CS.

Generally speaking more volume is good. I’m happy I can buy/sell most of my stocks instantly and that I don’t pay execution fees. I don’t think most average traders operate on a horizon/scale that’s directly competing with institutional funds.

Math class does not teach practical knowledge such as personal finance or health.

It teaches you how to work in a quant shop

You can just compute Sharpe

There’s no markup, regulations dictate that you must get NBBO or better

Maybe we should preemptively put them in internment camps until the war is over, just in case

I got a 718 Cayman which I particularly enjoy because of how barren the interior is. It has a screen with CarPlay which can be helpful for pulling up maps, a rear view camera, and lane change assist (which is just a red light by each mirror). Mostly analog tach too.

It’s just a car that’s meant to drive and not do much more, and it makes me sad seeing how rare that’s become.

It’s all gameable, they could make your compensation mostly bonus based so they didn’t have to pay out your full comp.

The exchanges already charge fees per order https://www.nyse.com/publicdocs/nyse/markets/nyse-arca/NYSE_...

How would that work? Would you randomly select a single order posted, go by market participant (like randomly select some entities that posted a trade in this window), and would you allow prices to move during this window?

Brokers are required to give you NBBO or better. You could set up a direct connection to an exchange if you were willing to pay and were sufficiently motivated to deal with all of that

Why shouldn’t people be allowed to do both? I don’t see much of an advantage to making the markets less agile.

It would be nice to be able to buy and sell stocks more than once a quarter, especially given plenty of events that do affect the perceived value of a company happen more frequently than that

Trading is a zero sum game, no one is ever going to give up their secret sauce

I think NYSE has higher uptime and tighter latency requirements.

Google doesn’t get in as much trouble if there’s some downtime, especially for consumer facing products

Hell, even Citadel hedge fund, after their ridiculous 50% performance fee

Do you have a source?

Citadel securities is the market maker, Citadel is the hedge fund and doesn’t have access to data from the other side

I don't care if exchanges trade back and forth all day to simulate fake demand (volume/exchanges between wallets that aren't actually going to transactions for goods/services aka crypto isn't really being used at $26b/day).

It sounds like you do care because you want to see “real” demand (unless I’m misinterpreting). This is the same reason wash trading is illegal in the regular markets
