June 1st was my last day at Jump Trading. I spent lots of time writing code in Python, Julia, and some C++. I worked with massive data sets. I built (testable) models of things. It was a mixture of a research and software development position. I enjoyed it, and the…
So yeah, Silicon Valley Bank (SVB) had a run last week. Over the weekend various (self interested) people posted takes that ranged between pleading for bailouts, begging FDIC/Fed/Treasury to do things, all the way through people (without obvious self interest) who seem to know and understand the processes…

You know, those idiots who take 2 parking slots. Or in this case, idiots in the (small) gym that insist they are using 2 machines at once. Not letting other people use them. And these are 2 of the more popular free weight stations: a Smith machine, and a dead…
