    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: seprom.info/build/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...

        why do you private your videos before you upload them

        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 does my phone tell me that this comment was posted before the video was?

    2. Thot Slayer 420

      what about a 2D progress block, width for data (so maybe mb or gb) and height for file count, never seen one, just thought of it

    3. kalle anka

      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

    4. RamennBowls

      "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...

    5. Reese606

      The only accurate progress bar is the 3DS one And no, not the blue one The one when your digitally downloading a game off of the eShop

      "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.

    15. Rory M

      Shout out to those 99 years that I was told it was gonna take for my game to open when I was 8.

    16. P Church

      This is why I leave and do something else when I’m downloading something. If it takes 5 minutes or 2 hours I’ll have something nice to come back to once I remember

      Someone tell computer making people to put this when turning on a computer after shutting it down

    26. Lordlouckster

      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!

    27. Hasan A

      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.

    28. Sideways

      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😅

    29. Eeee

      Bar: 1% to 99% : 20 minutes Bar: 99% to 100% : *10 hours*

    30. Viktória Vadon

      I agree, as long as the progress bar is moving (and not backwards!), I know something is happening!

      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.).

      Loading time estimates be like: 20 minutes 4 seconds 45 minutes 5 minutes 999999 hours

    37. Butter of Sorrow

      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.

      Is it just me or was the audio an video out of sync (I'm assuming deliberately)? If so nice choice.

    47. Tomáš Lipták

      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.

      You look young and old at the same time. That's a real mistyr to me, you should make a video about it!

    54. AK Nephtali

      The worst thing is when it goes to 99% immediately and then stays there for what feels like a millennium. Thank you for explaining this in your usual awesome way!

    55. SYS

      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.

    69. jeremiaas15

      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.

    70. LRC

      I love it when a simple download says "2 years remaining" or "∞ time remaining".

    97. Andy Delle

      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.
