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.

You don't have to learn it all at once and a lot of that new functionality is useful (I've used features from both C++17 and C++20 recently). I agree that learning C++ is hard though and the…
comment
I'm glad C++ has added more features, it is a much nicer language than it used to be. string_view from C++17 is very convenient and just this past week I had to use std::latch from C++20.

I used to work in an office where I only got cell service on cloudy days, I assume it had something to do with the clouds reflecting the signal.

Dynamic programming made very little sense to me when I first encountered it, then a few years later I read the DP section of Algorithms by Dasgupta, Papadimitriou, and Vazirani and it somehow clicked…
comment
I don't see why non-invertibility matters. Lots of useful features are non-invertible. Edit: and if you are dealing with real data sets or producing real datasets for analysis you will often have…

If you have evidence of pump and dump schemes occurring that will hold up in court you will likely make a lot of money from whistleblower awards.

They say that they don't see much evidence of wash trading on regulated exchanges so it seems regulation is good enough to solve a lot of these problems.

Yes

Okay, but search != adtech, so they can produce good software outside of adtech.
comment
Google has consistently better search results than every other search engine so this doesn't seem true to me.
comment
Doesn't Google have the expertise to copy this in house? They might have to react to it, but I don't see how it is a major threat unless they really botch their response.
comment
The C Programming Language is a decent overview of the language. After that using it in a real project is the best way to learn. If you know Linux pretty well and know what syscalls are then you might…

In most of the cases Scott cites the underlying thing being facilitated can be done via a normal financial system, some countries just don't have one that functions very well. So I don't see…

Phones and laptops get worse battery performance in cold weather and use similar batteries to EVs.

For many users of these exchanges their entire interest in crypto is speculation/trading, which requires them to store their crypto with an exchange so they can trade it because the costs associa…

I read his book Mason & Dixon and knew just enough of the history to recognize that there were tons of references going over my head. Maybe the smartest person I know loves his books and gets a lo…

They have to execute at or better than the national best bid and offer so you are getting at or better than the price you'd get if you posted a marketable order to an exchange. I don't see h…
comment
Delay in settlements shouldn't matter in the case you described, and the specific problem you're describing is solved by using limit orders rather than market orders (of course, the order mi…

I hate how you can't command click on a link to open a page in a new tab. I do this all the time when comparing products on other sites since it makes it easy to switch back and forth between two…
comment
Exaggerated headline. Lots of production of various goods still going to places like Mexico, India, Vietnam, etc. Semiconductors moving back to the US is mostly a reaction to China's growing powe…

The article doesn't mention weather which seems to be one of the biggest reasons these never took off.
comment
They have published some really interesting books on EW during the cold war. The volume I have has a lot of info that I've been unable to find anywhere else.
comment
He sets it once like this before the loops. __m256i c = _mm256_set1_epi32(10001);
And then the disassembly has mov eax, 10001
vpbroadcastd ymm1, eax
before eac…
comment
That's basically the problem the article describes although he's using vector intrinsics too and it still reloads and broadcasts the constant before each loop.
comment
Sure, I don't disagree with that. But the existence of a backchannel is notable in itself and as far as I know wasn't publicly acknowledged.
comment
Red Plenty , a novel that is loosely about the invention of linear programming in the Soviet Union (a branch of mathematics, only somewhat related to computer programming). Good description of what t…
comment
There is an existing flow to report a tweet or account. This sort of backchannel communication is news and good to have documented. It's not about Biden or politics. If you read my comments you&#…
