Alright, well there's at least one that uses KDB. Agreed on C++ over C, but given that we're talking to someone that's calling themselves a 'technologist' thought I would recommend the best book to get started.
I've had a lot of people on Hacker News very confidently tell me that I have no idea what I'm talking about on this topic. For a long time I thought I was just dumb, but still employed years later and have realized that most of the people that 'correct' me have exactly 0 experience.
This thread is why y'all need to focus on engineering and leave finance to professionals. Banks have assets (mostly bonds) and liabilities (mostly deposits).
Both of these items have a duration. They have to match the duration between their assets and their liabilities or they end up insolvent. If enough of the depositors try to pull their money out of the bank, then that reduces the duration of the banks liabilities, and the bank won't be able to move quickly enough to sell their assets to stay solvent.
The tech companies that are complaining about FDIC intervention caused their own problems because they are panicked morons.
Even more ridiculous is any one of these mega tech firms could probably step in and solve this situation with a cash infusion. They would almost certainly come out ahead because they would be buying a claim on the bank's assets for less than they are worth. But they won't. Because they don't know what they're doing.
What happened here is no different than what has happened in every banking crisis pre-08. The economy will be fine, someone like Berkshire Hathaway will make a stupid amount of money and customers will blame a bank for a problem that they created by being stupid.
The efficient markets hypothesis does not, and has not, stood up to empirical research since it was first invented. The reason that it's a hypothesis, and not a theory, is that it's impossible to disprove because all of evidence that disagrees with it is dismissed as spurious.
Society was told for thousands of years that astrology could predict the future and we believed it. But turns out, it couldn't.
Society was told for decades that "technical analysis" couldn't work because any advantage would be arbitraged away. Turns out, that was a bunch of BS and we now have very strong evidence for the basis of "technical analysis", momentum, going all the way back to the advent of financial markets.
