As superb a piece of software as SQLite is, it's definitely still missing features that many would use. No FULL OUTER JOINs is maybe the most notable that I've encountered. https://www.sqlite.org/omitted.html

While these are certainly tech companies, Amazon and Apple both primarily make their money by selling physical things. I believe part of his reservation in “tech” historically has been with companies that do not - not that he thinks they’re

I'm not sure I agree that that's pedantic, or understand what you're referring to. The only reference to "next" or "same" on that page is for offline instructions (i.e. talking to a human), which cannot b

These aren't SLAs, they're operating hours. Transfers are essentially instantaneous.

I’m tempted to subscribe, if only it weren’t so comically expensive.

Agadmator may be "mediocre" (aka still better at chess than anyone I've ever met in person) and his analysis simplistic, but that might actually help him on his mission. Which seems to be to make chess as consumable as a mai

Another similarity: outsiders (and even insiders) aren't sure whether the whole thing is a joke or not.

Yep, and it's not some new-fangled form of finance, it is the entire history of finance. There is a hierarchy of money, and it has always been so. I highly recommend this Coursera course to shed light on this: https://www.c

It’s because considerably less capital is required to clear an Apple trade, because it is a much less volatile stock.

I don't want to come out strongly in favor of payment-for-order-flow (the term for RH's relationship with HFTs), but since you seem so incredulous about it, let me offer the non-cynical explanation to help build intuition: RH trad

Oh it’s very clearly observer’s bias, I don’t mean to suggest otherwise. That’s exactly my point. I just wanted to push back on the idea that there are two kinds of people - those who don’t live in cities, and those who live in cities relu

Baked into this theory is the belief that people only live in cities for job prospects, and not because they want to for every other part of their life. The belief is untrue at least for me and everyone I know.

I'm not suggesting that all economic transactions are zero sum. I'm just using that idea to expose what value really is. > No value is created or destroyed (outside of trading fees), just transferred between parties. That tran

I’m not the first person on HN to say it, but I’ll say it here - by this definition of zero sum, are not all economic transactions zero sum?

All of the other answers have good points but are missing the one that matters: the musician’s union requires it. Every Broadway theatre has a minimum number of musicians (depending on the space) if a musical is being performed.

I don’t want to defend the traditional IPO process too much, but “only” is a strong word. One possible benefit from a “pop” is that it makes it more likely for investors to want to participate in future IPOs. That is, the pop from an earlie

Front running is a very specific malfeasance, and this release does not accuse Robinhood of it, by name or otherwise.

It’s just as easy to say that solutions are unlikely to come from anything but technology. But organizing/protesting/demanding might be a big part of the way we get there.

An average of a financial portfolio over time won’t be a good measure of risk taking during that time period. Consider, for example, a portfolio of two securities A and B who have mostly offsetting risk. If you own one million units of A on
