The march of progress

progress

One of the things that has always been a challenge for developers is the ‘progress bar’. It can be very difficult to predict in advance just how long something is going to take: you work it out for, say, a typical operating system update on the typical machine and then you find that some users have 100,000 things in their Trash, or are in the midst of a backup to a slow external drive, or whatever…

Installing Mac OS X Yosemite this morning, the progress bar sat at ‘About one minute remaining’ for well over half an hour, so I went and did some Googling and found that I was not alone – many people waited much longer than that, but it always completed in the end. Of course, like a watched pot, it will never get there if you’re sitting waiting for it, so you have to go and do something else. Usually, it is just a mild annoyance for impatient enthusiasts like me, but occasionally it can be a more serious problem if you’re told something will take 30 mins, for example, and you therefore assume you can do it before your appointment in an hour’s time.

Anyway, watching the slowly-progressing pixels gave me an idea…

There are tens of millions of people who will be going through this process over the next few months: surely you could improve the accuracy of their progress bars by uploading the timing information at the end of each installation, along with basic information about the system and then using that to give more accurate estimates to those with similar machines, similar disk usage, etc?
