What is Plaid's long-term competitive advantage? It made sense when scraping was the only solution (albeit an extremely dangerous one) but now banks are launching their own APIs, which is allowing some competitors to come in with free

In addition to the sibling’s comment on explicitly passing inna comparator, note that std::map is an ordered dictionary and requires an ordering on your elements. It sounds like you may have preferred hash_map

Given that it was a data science interview is it possible they were expecting it to be a fast simple thing (some pandas, some sklearn, you’re done) and instead he did some long slow manual thing so they rejected him?

Hedge funds can also be a good testbed for technologies, while “do good” companies can use it as an excuse to be bad on the inside. I am fascinated with the potential of large scale crowdsourcing in data science, and finance seems the most

Regardless of intent, SIPC has around $3 Billion saved up to protect all brokerage accounts in the US. They literally cannot afford to insure Robinhood if they wanted.

Not quite. One reason why many passive indices are market-cap weighted is so they do not have to regularly trade. Suppose a fund needs to be 1% AMZN. Now you fire up a hype train and the price of AMZN doubles. It now represents twice as mu

Reordering a divergent series can indeed give you any result you want. This is not reordering though, it’s called Cesàro summation. It won’t always get you an answer, but if it does then the answer is unique and reacts nicely to sums and p

Actually that’s an example of a soft fork. When you change the rules to make them more restrictive (add limits, decrease block size, block addresses, etc) those running the old version will find the new blocks valid so will try to build on

That is actually fascinating. You could build a ledger on top of github, transactions are push requests,there’d be a centralized party approving valid push requests and merging forks, but following a standardized formula that anyone can che

Good point, that really is the key. However, itjust turns it into the almost equivalent problem of: why assume Gaussian error terms, and the rest of the article does a good job at motivating this.
