marosgrego··on The paper that keeps showing up
You can think of `i` as a rotation by 90 degrees counterclockwise. You do it twice and the real number line gets reflected (as if multiplied by -1). It is what multiplying by i actually does to the complex plane.
marosgrego··on Turns are better than radians
cos and sin are the x and y coordinates as you turn around the unit circle in unit speed.
marosgrego··on Rewriting my blog in Rust for fun and profit
If you're interested in this, a while ago, for my personal photo site with image galleries[1], I wrote a fast static site generator in Rust[0], which also supports plugins now.
