What I Wish I'd Known About Equity Before Joining A Unicorn

Disclaimer: This piece is written anonymously. The names of a few particular companies are mentioned, but as common examples only.

This is a short write-up on things that I wish I'd known and considered before joining a private company (aka startup, aka unicorn in some cases). I'm not trying to make the case that you should never join a private company, but the power imbalance between founder and employee is extreme, and that potential candidates would

The Three.js Blender exporter has been broken for at least the last 10 releases of Three.js. It's had at least 20 individual authors and contributors, most of whom have left the project never to return. Nevertheless, I have successfully imported animated (both with rigging and morph target) meshes into Three.js. Here's all the things I've encountered which you need to know about:

• The exporter flips all vertices, faces, etc in the mesh you export. There used to be a "Flip Y/Z" option in the exporter, but it was removed when the exporter was rewritten. Since then speculation is the Blender API changed, or some other change after this one mangled the faces on export. For now we're stuck with it until we track it down.
• mrdoob/three.js#8723 Invalid json is exported for all files with animations, so you have to delete a key manually from the json
• mrdoob/three.js#8710 morph target exporting doesn't work with "a

# put this in your .bash_profile

# Piece-by-Piece Explanation:
# the if condition makes sure we only screw with $PROMPT_COMMAND if we're in an iTerm environment
# iTerm happens to give each session a unique $ITERM_SESSION_ID we can use, $ITERM_PROFILE is an option too
# the $PROMPT_COMMAND environment variable is executed every time a command is run

/* Quadtree by Ozan Turgut (ozanturgut@gmail.com)

   A Quadtree is a structure for managing many nodes interacting in space by
   organizing them within a tree, where each node contains elements which may
   interact with other elements within the node. This is particularly useful in
   collision detection, in which a brute-force algorithm requires the checking of
   every element against every other element, regardless of their distance in space.

   This quadtree handles object in 2d space by their bounding boxes. It splits
   a node once it exceeds the object limit per-node. When a node is split, it's
