I saw this tweet by Daniel Nemenyi today:
I use #emacs, not Word, for writing. It was playing up. Typing became sluggish. So I ran its profiler, typed a few lines, ran profiler-report and found a function gobbling up CPU. Quick search, clear what I’d done wrong, how to fix.
Try that with your Word next time it acts up! pic.twitter.com/94T1lPYoD5

He makes a good point. With Emacs it’s pretty easy to solve a lot of problems that would be absolutely opaque with most other editors let alone the software whose name must not be mentioned.
If you follow the thread, he explains that the error was caused by his using follow-mode with LaTeX-mode. That meant that bottom of screen calculations had to be constantly made. Notice that there’s no particularly high powered debugging going on here. He simply ran the profiler, discovered where Emacs was spending its time, and used that to figure out what had happened.
Another example of the power of Emacs.
