any kind of numerical method (RKs, FDs, CN) where the n-th step a_n = f(a_(n-1)) and hence you define NUM_STEPS and the the result is a[NUM_STEPS] where a is your numerical lattice. you could work in a 0-based index and your n-th step is a_

i think 4 and 5 are using skylake and kaby lake which is a minor perf improvement. the cpu comparison is not very interesting. we will have to wait for the next intel 'tick' before cpu comparison becomes meaningful again.

for index funds the core problems are estimating risk and return, minimizing effect of uncertainty and std err on portfolio tracking, and fast optimization for large portfolios (>1000 assets). these are fairly long term problems so stoch

no I don't use a waterbath, I measure temp of water when first mixed and also room temps randomly through the fermentation process. I also don't have a sub-gram scale, I improvise by marking out levels inside a measuring spoon...

I've already done that. what kind of geek do you think I am! ;) baker's percentages are the easy part. I also log temperatures and fermentation times. analysing the effect of those two inputs on bread quality is much harder.

this guy reminds me of Ken Forkish whose book "Flour Water Salt Yeast" is a James Beard award winner (like J Kenji's "The Food Lab") and is considered one of the bibles of bread making. he also owns a bakery in Port
