> by getting the whole parser onto a single screen, I find that I can get the whole problem into my brain’s working memory and avoid burning cycles scrolling up and down to pin down butterflies bugs. I haven't seen many developers do this: get a computer screen that can stand in the portrait position. My setup currently is: laptop monitor + 27" screen in portrait. I never have the trouble of scrolling back up and down again when it comes to reading code.
