Excerpt from Aaron Brown’s “Red-Blooded Risk: The Secret History of Wall Street” (chapter 10) on gold money, paper money, and derivatives

To start a business with precious metal money, you need to have or to find an investor with enough precious metal to buy all the assets you need to start generating cash sales. To start a business with paper money, you need to find a bank willing to supply you with pieces of paper. Neither you nor the bank need have any net worth, although in practice banks tend to maintain net worth equal to a fraction of the loans they make. Even so, the amount of capital required to start the business with paper money lent by a bank is much less than the total value of the assets required. What is essential is that the bank’s lending standards are low enough to approve your loan, but high enough to make its paper money acceptable enough to acquire the assets you need.

To start a business with derivative money, you identify all assets you require and all products you will deliver in the future. Of course, there is uncertainty around these things, especially the amount and quality of products you will deliver. You don’t hav

Aaron Brown on risk and sleep deprivation

Aaron Brown, on Chat with Traders episode 149, on risk and sleep deprivation.

The other half of risk. In poker at first you can just play quantitatively. You know the numbers, you know the probabilities. At low levels you collected money just by probability. But as you get higher and higher and you start to get some of the best players in the country, you realize there’s a whole other level you gotta get and it’s all done by your unconscious brain. You can’t calculate it, you gotta feel it, and you gotta train your unconscious brain to play poker. It’s a powerful computer up there … but it doesn’t know how to play poker. And your conscious brain is very weak, can’t multiply two three digit numbers together which a computer can do easily. So your conscious brain is relegated tasks like coming up with advertising jingles and wondering which celebrity marriages are in trouble while your unconscious brain handles heartbeat and respiration and whether you’

TypeScript (and, for ES2015 and above, JavaScript) port of Python's `enumerate` to make index-value pairs.
View enumerate.ts
* Generates `[index, value]` 2-tuples, so you can `for (let [index, value] of enumerate(v) {...})`.
* @param v array or iterable iterator to enumerate
* @param n starting number (defaults to 0)
* Hat tip:
export function* enumerate<T>(v: T[]|IterableIterator<T>, n: number = 0): IterableIterator<[number, T]> {
for (let x of v) { yield [n++, x]; }

View bestGroupBy.ts
* Like "groupBy", but only track the "best" group.
* @param arr Array of values
* @param grouper Mapper from elements of array to some group. Should be pure (it'll be called on first element twice).
* @param compare Compare two groups: if `compare(x, y) > 0`, then `x > y`, and similarly `=` and `<`.
* @return array containing the best group as first element, then the array of entries in that group.
* I only care about `compare`'s output's sign/zero, so it doesn't need to be a true distance.
export function bestGroupBy<T, U>(arr: T[], grouper: (x: T) => U, compare: (x: U, y: U) => number): [U, T[]] {
