@mafintosh said most of this, I just wrote it down

how to destroy/end streams in node >= 0.10

• usually you call .destroy() if it has .destroy
• if it doesnt have .destroy you are out of luck and the stream should upgrade to use e.g. newer through2
• in request you call .abort() (this should get fixed to use .destroy())
• .end() tries to end the stream gracefully

# You will learn why `make` is so great, and why, despite its "weird" syntax,
# it is actually a highly expressive, efficient, and powerful way to build

# Once you're done here, go to

Vim without NERD tree or CtrlP

I used to use NERD tree for quite a while, then switched to CtrlP for something a little more lightweight. My setup now includes zero file browser or tree view, and instead uses native Vim fuzzy search and auto-directory switching.

Fuzzy Search

There is a super sweet feature in Vim whereby you can fuzzy find your files using **/*, e.g.:

:vs **/*<partial file name><Tab>
