On the latest episode of the ArrayCast we talk to Joel Kaplan, founder of 1010data.
Joel ran the Algorithmic Proprietary Trading group at Morgan Stanley for many years. In 1985 he hired Arthur Whitney, who wrote for the group a stripped-for-speed APL subset they called A, which became A+, for twenty years the Morgan platform for trading applications, and eventually kdb+ and the q language.
In this episode Joel talks to us about the difference between vector and scalar programming languages, about why some languages flourish, and about selling 1010data for half a billion dollars.
