For the author: "Benchmarking page to choose good parameters..." seems to spin forever and I don't feel the device getting warm. Don't have an error console on mobile so not sure what's up but this is on an Android webview browser. Maybe add an onerror event handler to at least show the user this spinner is going nowhere? Edit: wait, it did complete now that I've not used the skip to demo link and read the article. "Benchmark complete! Using 29000 iterations". Maybe mention that it can take several minutes on a modern device? Or a progress indicator? Now that I'm running the password guesser, the device does get warm in the usual spot for cpu load. Cool way to visualise the method! After five minutes, 6 out of 10 guesses have the right first character, and of those, 2 the right second character. Am I extrapolating correctly if I guess it'll need to do this 4 more times so some 20 minutes? Battery use is 30%./hour currently so about 10% of a full charge would be 1.1 Wh Edit2: the number of correct prefixes is decreasing after 10~15 minutes. This will take forever
