I'm an HP-12C guy since working on a trading desk and have 2 of the OG bronze colored ones and 2 of the HP-12C Platinum that are faster and silvery. But since I've been re-learning math with Math Academy I'm drawn to pick this puppy up. Should I be looking at an HP equivalent, though, since I'm an RPN convert?

An agricultural company hedging the price of soybeans is precisely hedging, not speculation. The insider information they have is their supply/demand/pricing picture. That's different than the colloquial definition of insider information which I've always taken to tie to event occurrence (or not).

I'm surprised when people are surprised that Google's interview process is obnoxious. That's pretty well established by this point, both by Google employees and others.

Probably should take the logo off of the image of the safe if the intent is to avoid naming the company.

"It is intuitively obvious that an open access hedge fund will generate more intelligence than a closed system built on a pre-internet, pre-cryptocurrency, pre-AI organizational design."

Really? Because the folks with the magic black box aren't capable of funding an Interactive Brokers account to keep 100% of their upside and 100% of their IP?

(Also: risk management and order handling are harder problems than signal generation.)

Among other factors, salespeople have a large variable component to their compensation. They tend to be highly economic animals in a way that most engineers are not. Hence a former boss can easily convince them to join up by making a compelling argument about their prospective earnings.

It also skips the part where the team being hired gets a large signing bonus.

I'd take it a step further and argue that asset appreciation was an intended outcome of ZIRP.
