Behind every "100% written in Python" is a "56% written in C++" (This is not an attack on the Genesis authors. Genesis is really cool and @taichi_lang is first in their list of acknowledgments. People just focus too much on the 100% Python aspect of it.)
WTF?! New open-source physics AI engine absolutely insane! 🤯 Genesis is a new physics engine that combines ultra-fast simulation with generative capabilities to create dynamic 4D worlds for robotics and physics. TL;DR: 🚀 430,000x faster than real-time physics simulation,

The next few years will just be this over and over again.

My function requires two (anonymous) functions as arguments. Here is how I check that they have the correct type signature. Is there a better way? #JuliaLang

I just executed my first true arbitrage. $0.72 of risk free profit! After slippage, the position entry cost was exactly $50. Allocations were calculated using convex optimization in #JuliaLang

Turns out that multiple dispatch doesn't work if you use kwargs, so you can't have slippage_prices(market; default_allocation :: Float64) and slippage_prices(market; allocations :: Dict) The second just overwrites the first. #JuliaLang

I feel like #JuliaLang hasn't solved the two language problem. Whenever I am finished with a piece of software I want to rewrite it in Rust, so that it's stable at runtime.

"T = b × log₂ (n + 1) In plain English: More choices = exponentially more brain processing time." no, that's quite literally the opposite of what that means
Hick's Law states: The more options you give users, the longer they take to make a decision. Here's the fancy formula: T = b × log₂ (n + 1) In plain English: More choices = exponentially more brain processing time.

Not a good sign when a project's code of conduct is easier to find on their website than their github repo.

The internet needs more notation tables (@lilianweng 's blog)
When researchers don't bother to define the symbols they use, it's actually not a sign of elitism but of parochialism. they just never read anything outside of their narrow field of expertise where everyone knows what γ means.

#JuliaLang pattern #281: using multiple dispatch instead of checking the type of a function argument

why annualize your sharpe ratio? because counting your money less often doesn't make you richer. a random walk looked at hourly or daily should have the same risk-adjusted return, yet the unannualized sharpe ratio penalizes high frequencies.
