4 minutes remaining. Then 15 seconds. Then 5 hours. Why can't computers just tell you how long something's going to take? • MORE BASICS: nlposts.info/chart/PL96C35uN7xGLLeET0dOWaKHkAlPsrkcha.html

I'm having to film back in the Tiny Room against green-screen again, as lockdown means the Centre for Computing History is closed! Hopefully they'll be open again soon, although that depends on a very different kind of progress...

How did you put in the time estimate of this video in the script as you were recoring? I slowed down the video speed to .25 but can't see where you may have stitched two takes together.

"Why can't computers just tell me how long something is going to take?" Because progress bars don't show you time... they show (suprise!) progress.

Solution: Have individual progress bars for each step. Step 1/4: 10% Step 1/4: 20% ... Step 1/4: 100% Step 2/4: 10% Step 2/4: 20% ... Step 4/4: 90% Step 4/4: Done!

The one thing I wish I could do when it came to downloading something is allocate as much resources to downloading as possible. I love that you can still Watch Netflix, have a conference call, and edit a video in Adobe After affects, while downloading somthing, but sometimes I just want to download something, walk away and have the computer just worry about downloading or moving the file.

This is the corollary to Windows 10 offering to kill any app that takes more than 15 seconds to do something - apparently Windows isn’t seeing a progress bar😅

That's also why many programmers have gone the other way and just show "progress indicator" instead of progress bars. Like the spinning wheel on Windows. It just shows that the PC didn't freeze and is still working, but you don't have any indication on how long it's going to take. Also if "time" isn't a parameter itself then the progress bar can never be give you a proper "remaining time". A countdown is always accurate because the time itself is the parameter that makes it work. Filetransfer ist based on the files and not on the time, so it will finish when it is finished, not when a certain amount of seconds have passed (like the queue in the supermarket. Fewer people doesn't mean the line is faster. There are just fewer people in front of you.).

Personally I like loading screens that tell you what exactly they're doing, like most source and goldsource engine games. "Validating game resources." "Sending client info." That kind of thing.

I think the best loading screens are when there are actually two (think winrar) one for the whole process and the other for individual processes. From there you can see that it is actually doing something.

A thing the program could do to resolve, or at least find a more smooth load, is by logging the time, taking the estimated time that it took, and telling you that number. If it was a game, it could show how long it had taken the last 10 times, (assuming you would've loaded it that many times), and let's say a file upload, it could track how long it would take for 100 files, and estimate the amount of time, that this would take because its 10x times larger, or half the size = it would be 10 times longer or ½ times faster.

I have four letters for you: RTOS. A Real Time Operating System (RTOS) provides hard or soft guarantees of how long a program will take, in instruction cycles. Sometimes this is critically important, for instance if the machine is doing quantitative chemistry and it needs to error out if the reaction time wasn't very close to 90 seconds. It's fun stuff.

What I'd like to know is, how is it possible that progress bars always show, even if for a split second, 100%. Surely, if that were truth, the next thing would pop up instead.

One way to look at this issue is as follows: What do you want the computer to spend it's time resources doing? 1) Analyzing all aspects of the task and the current conditions which could provide a very accurate time estimate. 2) Concentrate on moving the data or crunching it with time calculations done on available wait times. It's often the case where an accurate completion time estimate would take longer than just doing the requested task.
