i have a pc at home which is often on, but not so often used. i'd like it to hibernate most of the time, unless i want to use it or it is doing something itself. it's possible, stringing together a few things:
function lazy_nvm {
unset -f nvm
unset -f npm
unset -f node
unset -f npx
export NVM_DIR="$HOME/.nvm"
[ -s "$NVM_DIR/" ] && . "$NVM_DIR/" # linux

  • when should this compacter run?
    • every n actions added (compactEvery)
    • when history is at n length (highWaterMark, compactAtLength)
  • can the function signal when it should?
    • run the compacter every time
    • needs a private state (below) or
    • getCompacter({ n, highwater }) => compactingDispatcher()

we can compactingReducer, basically searches the last 50 actions for "stop" or

Voronoi Diagram with Force Directed Nodes and Delaunay Links

Created by Christopher Manning


Nodes are linked to nodes in neighboring cells. The cell's color is a function of its area.

The white lines are the Delaunay triangulation and the purple cells are the Voronoi diagram.
