wmayner / OrbitControls.js
Last active January 25, 2018 14:48
Fork of three.js Orbit Controls that allows binding its event handlers to arbitrary elements, rather than just the given `domElement`. Useful when adding sibling DOM elements to the canvas, e.g. labels for objects.

The Tao of Unix

  1. Rule of Modularity: Write simple parts connected by clean interfaces.
  2. Rule of Clarity: Clarity is better than cleverness.
  3. Rule of Composition: Design programs to be connected to other programs.
  4. Rule of Separation: Separate policy from mechanism; separate interfaces from engines.
  5. Rule of Simplicity: Design for simplicity; add complexity only where you must.
  6. Rule of Parsimony: Write a big program only when it is clear by demonstration that nothing else will do.
  7. Rule of Transparency: Design for visibility to make inspection and debugging easier.

Another reason why numbering should start at zero

Why numbering should start at zero

Elaborating on the reasons given in Dijkstra's memo on the topic, we observe the following:

1-based indexing

  • Ranges are of the form 1 ≤ i < N + 1.
  • The last element of a sequence has index N.

"""
Memory-aware LRU Cache function decorator
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
A modification of the builtin ``functools.lru_cache`` decorator that takes an
additional keyword argument, ``use_memory_up_to``. The cache is considered full
if there are fewer than ``use_memory_up_to`` bytes of memory available.

wmayner.zsh-theme

Forked from @agnoster's zsh theme. Incorporates changes from @smileart's fork.

Modifications in this fork:

  • The current path is right aligned, so it's out of the way when working in deeply nested directories. The main, left-aligned prompt only the current directory's name.
