Efficient and pleasurable programming is all about having a “fast feedback cycle”:

BrowserSync makes your tweaking and testing faster by synchronising file changes and interactions across multiple devices. It’s wicked-fast and totally free.

How long can you work on making a routine task more efficient before you’re spending more time than you save? (across 5 years)

(via xkcd: Is It Worth the Time? )

Programmers waste enormous amounts of time thinking about, or worrying about, the speed of noncritical parts of their programs, and these attempts at efficiency actually have a strong negative impact when debugging and maintenance are considered. We should forget about small efficiencies, say about 97% of the time: premature optimization is the root of all evil. Yet we should not pass up our opportunities in that critical 3%.

“Premature optimization is the root of all evil” confirmed by the author in A note from Donald Knuth about TAOCP
