Too Long; Didn't Read
I wanted to get a quick picture of what the <a href="https://hackernoon.com/tagged/processes" target="_blank">processes</a> on my <a href="https://hackernoon.com/tagged/computerr" target="_blank">computer</a> were doing in the background, so I turned to <a href="https://en.wikipedia.org/wiki/DTrace" target="_blank">DTrace</a> (shout out to Julia Evans for <a href="https://jvns.ca/blog/2016/07/03/debugging-tools-i-love/" target="_blank">getting me excited about it</a>), which can tell me handy things like “who’s opening up which files?” and “what system calls are being made?”
