    u(t) is called 60 times per second.
    t: Elapsed time in seconds.
    S: Shorthand for Math.sin.
    C: Shorthand for Math.cos.
    T: Shorthand for Math.tan.
    R: Function that generates rgba-strings, usage ex.: R(255, 255, 255, 0.5)
    c: A 1920x1080 canvas.
    x: A 2D context for that canvas.

Variable initialisation with only +2 chars (hack)

u/tomxor

Saves up to 4 chars vs t||(a=1e3);
u/katkip

hmmm

u/tomxor

Haha, regex cannot parse an AST... also: }{a = 1
u/tomxor

I take that back, not sure what's going on, can't see much happening in between textarea and eval in iframe.
u/tomxor

Ahh, i get it: function u(t) {} {a=1} the end part is valid if it's an object literal or ES6 destructuring.
u/tomxor

You could actually use this for intialisation variables instead of checking !t... might be smaller
u/tomxor

i.e }{a=1 rather than !t||(a=1) (saves 4 chars)

A colorization of sorts, for d/14116

Nice, looks more like microcircuitry with colour.

If you take two random integers of at most 7 digits each, what is the probability that they are relatively prime? This simulation suggests somewhere around 60%

u/taupelink

In the graph, the x-axis shows number of trials, modulo 1920 (i.e. with wraparound). The y-axis shows % of trials with GCD 1, with 0% at bottom and 100% at top.
u/taupelink

After a little Web searching: Under more general conditions, the precise answer appears to be 6/π^2, or about .608. See, e.g., https://www.cut-the-knot.org/m/Probability/T…
