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: svdown.info/put/PL96C35uN7xGLLeET0dOWaKHkAlPsrkcha

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.

It’s actually placebo its jus randomly stoping at random intervals and thats why it stops at 99% cuz it’s actually at 70% or 50% or maybe even 30%

Things to do do, to make progress bar faster: Buy an ssd Upgrade ram (and probably buy more ram than you have on a computer) Buy better proccesor Buy better router/modem and get faster internet Buy faster hdd(s) Install linux Congratulations!!! Your game/program now loads/downloads/installs faster!

I just like windows' there are 7 years left for finish copying your files. While showing me the speed and amount of data left, which definitely won't be 7 years if i divide data amount by speed.

Best solution would be to put a title to every segemt of the progress bar. Anyone who watches porn on the hub will have found this out. If you dont care about foreplay you know exactly on te second to skip to, to skip that part. So for a progress bar for a install. Just title the segement so that we know what part the computer is working on and we know what we might think of upgrading

"The most important job is to reassure that yes, things are happening, progress it being made" That moment when the progress bar is stuck at 99% for about 28 minutes...

"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.
