Hedge Fund -> Defense Industry -> Big Tech
My career has mostly been at the intersection of hardware and software (including a couple of years designing FPGA gateware) and focused on designing and developing correct, performant systems, but I've been paid to do everything from PCB design to React frontends.
I also have an interest in improving clinical trials for novel therapeutics.

Jane Street isn't a hedge fund so I'm not sure why you're lumping in criticism of hedge funds with criticism of Jane Street. I'm sure some hedge funds have been scams, and probably…

Yes, so the upside is capped but you get to set the cap based on what call you sell. The bet you're making is that the stock won't appreciate enough for the other party to exercise the call …

Some small percentage probably can and it is easy to fool yourself that you are doing better than you are (especially prior to 2022 when most things with retail interest just went up for over a decade…

Yes, which is what the GP post said, they lose their unvested stock. By future vested I meant, stock that will vest after they are laid off. Could've been clearer I guess.

LTCM actually was doing a lot of the risk management people later said they should do. Their problem was the trades they were doing were more crowded than the realized and they couldn't unwind th…

Meta does pay higher (maybe not 2x higher) and the message in OP says employees will get their November 2022 vesting, which implies they won't get any future vested stock.

Part of the job of the modeler is to make good decisions about the parameters and their uncertainties. If they are systematically overestimating CO2 and getting high predictions as a result then they …

It depends on how you define "quite well". They are definitely directionally correct and in the right ballpark. This is a politically sensitive research area so the researchers are incentivi…

They are all wrong. Historically they've overpredicted warming, and then the models are updated to fit the (new) data better. They perform worse in areas with less data, like polar regions. To fo…

> The media industry is notoriously slow to adopt new technologies This doesn't seem right, wasn't the film industry one of the first big users of 3d graphics and the computer hardware (e…

You have to learn pointers in Rust too and I don't think the STL is any more complicated than Rust's standard library.
comment
C++ has improved a lot over the past decade or so. Compilers can add runtime checks now that make most memory bugs easy to detect and diagnose. C++ has plenty of warts and legacy stuff that you wouldn…
comment
If people think C++ is hard to learn and attracts opinionated people boy are they in for a surprise when they start using Rust.
comment
> C++ as a whole should be deprecated -- and no new projects should use C++ (unless for some very odd and specific reason). It's quite a bit easier than Rust and no other popular language has…

There are more scientists now than ever before. I don't see how what you're saying fits the facts. There is probably more funding available for research that has little expectation of ever l…

Arthur Whitney's compiler for a language "isomorphic to c": https://kparc.com/b/ . Amazing that someone can write correct, fast code like that.…

Where does he say that how fast you can code is the most important metric?

Yeah that's one of my pet peeves with lean-startup type stuff. It's great for consumer products that aren't too different from what people are used to but not that useful for work that …

One trend I'd like to see is more dense UIs. You can tell a lot of web and desktop GUIs are designed by developers with wide monitors because when you go to use those apps on a laptop with a smal…

Most modern ML techniques do a poor job on these types of problems too unless they have a lot of data (hence the reference to sparsity) or assume structure that requires domain specific modeling to ca…

Can't you just wrap the connection handling code with some logic that automatically executes the pragma?
comment
I have had it as an interview question before.

You need algebra to make things. Lots of machining involves algebra and geometry. Maybe it isn't taught that well, and maybe kids would learn it better if they were motivated by practical example…

Numerical Linear Algebra by Trefethen and Bau is the resource I've seen recommended most often. I've only read the first few chapters but they are good and useful.

Bernanke's memoir is good. Easy to take shots at someone like him, but he was one of the most important decision makers in the world post-financial crisis and the world would likely be worse off …
