ANECDOTE

Handmade Hero Fueled Deep Learning

  • Jimmy learned programming by obsessively following Handmade Hero and coding along, which beat his university classes for depth.
  • He built a chess engine and learned bit-level thinking that shaped his low-level programming style.
INSIGHT

Code Points Versus Encodings

  • Unicode defines abstract code points but leaves memory representation to encodings like UTF-8 or UTF-32.
  • Shaping and higher text algorithms operate on decoded code points, so decoding is a required preprocessing step.
INSIGHT

From Bitmaps To Vector Outlines

  • Fonts moved from bitmaps to scalable outlines using Bezier curves and ray casting for rasterization.
  • This allowed smooth scaling and preserved glyph geometry across resolutions.
