Ohh HeLLo ThErE
hi
hiii
oh
The most annoying thing is when it reaches 100% and then just sits there for another 3 days.
Or at 0% for 2 hours... Very cool windows update.
Standard windows xp behaviour use to be sometimes: set the progress bar to 90%, then begin what you have to do, upon finishing set it to 100%. now with windows 10 we have those dots that fly in, do a slow circle and fly out again, over and over again.
@@ChrisD__ This is scary true
I once heard a web designer talk about how sometimes a progress bar isn't even truly a progress bar, it's just a code or gif image set to raise up to around 90-99%, swap to a different bit of code or image and display that until it's just about finished, and then swap to a third bit of code or image that displays 100% (this is most common on websites or video game loading screens but I'm sure some program installers do this too). The real trick to it is like Tom said, making it a little janky so it _seems_ like a real progress bar.
@@ChrisD__ At the very least, as Linus had pointed out too, they don't take that much time with the updates nowadays.
Can't explain the fustration of things getting stuck at 99%
Then be prepared for the frustration of it being stuck at 100% and nothing happening

@@lethall6609 That's what he said. "the LAST 1%"
I once wrote a small program for a department in my company and they didn't think it was good enough. I added a small progress bar to the front that literally just incremented a counter at even intervals and they went nuts for how robust I had made it and loved it. It was a 3 second loop that flashed a modal with the word "loading..." and a progress bar that did nothing but count to 100 by 1 and it changed the perception of the complexity. I eventually took that out, citing a performance improvement.
Big brain
Really goes to show how little the non-techies know about tech
Anything animated is great🤣🤣
Perhaps not in your particular case but as someone who used to do a lot of programming for fun many moons ago, one word sums it up, 'feedback'. You'll know what I loathe if you are familiar with large commercial crap like SAP and anything designed around it for end user experiences which in my experience has little to none, or wildly unexpected or might as well be invisible user feedback.
If you display something for more than a few seconds and it isn't immediately obvious what you should be doing, you failed with your GUI (assuming you have one of course).
A lot of stuff has moved away from desktop software where I work and moved towards web front ends, oh god how terribly slow, fails a lot, has little to no feedback, half the time you only know something has worked or is working purely because you have sat through nothing happening so many times and confirmed the data via another method that wastes even more time..... and i'm ranting hahahaha!
@@MowLawner It's called providing a good user experience. If you make the user wait with no indication of what's/if any is happening, they will hate it.

Good ol' floppy drives "3%.... 4%.... 98% DONE"

Hey, its my favourite 40k youtuber. Neat.
You skipped the 2% after 98% but before done
Or netflix
The store where I used to work would reboot the self service computer after every customer so it could restore the default state of the machine. The software it had to launch after the reboot used to be stupidly slow to load some process that takes the progress bar between 3% and 78% (like 5-10 minutes, or at least it felt like it when there was a line to use it) and then only a few seconds to complete, until we upgraded the computer to a faster processor and SSD, and then the progress bar would just already be at 78% by the time you could see one.
My absolute favorite thing is when loading time estimates spit out stuff like "infinite" or "96 years." I don't see it happen as often anymore (and it's also unhelpful) but it's hilarious.

@@Darenz-cg9zg maybe it subtracted 50 from 24 (which would become 26) instead of 50% of 24.

@@quixomega You are not a programming manager, then. At least I hope not. Sometimes problems in complex codebases are incredibly confusing so you try a hail mary in an attempt to fix it and it works.

No, it will get stuck where it's at for 6 months, then suddenly finish.
My old internet setup was extremely prone to dropping connections temporarily, and it was really funny watching "time remaining" estimates steadily climb by several days of time before suddenly jolting back to a few minutes
Had satellite internet limited to 10 gigabytes before. When it ran out it reduced to dial-up speed. A download once shot up to 4 years.
So one day I was using my dell Inspiron 15 3000to download a steam game called world of tonks, it went like this from one hour to hour five hours three days 365+ more than a year. (It took a day and a half to install)
One time not very long ago I was updating a steam game, the estimating time remaining started at 5 minutes and steadily increased until it said "more than one year", before going back to 20 minutes
Windows 10's updates take "meh, good enough" a little too casually though. It can sit on 21% for three-quarters of an hour then jump to 81% for 15 minutes more and then 98% and done in a few seconds. I suspect they decided to only update the progress bar after completion of (e.g.) each file installed, and that in the above scenario there are some really huge files that are complex to install and a few smaller / simpler files after that.

As someone that has actually coded a very basic progress bar before, yes. It's near impossible to make it smooth, and yes, my answer was exactly the same. It shows that it's making progress and not frozen, and that's all that really matters. I have a new respect for progress bars after trying to make one actually function, and I had tutorials to figure out how to do it.
It's not very sophisticated to increment value by a little every time something completes... Estimating time is whole can of worms.
How about a neural network that learns from different machine settings how long tve overall process is going to take
I mean... How effective is it at showing that there is in fact progress going on when it sits unchanging at 25% for two minutes before racing all the way from there to 68% in less than two seconds.
I remember from some games, that they would have an installer that had: a blue progress bar with a percentage. And on the left side of the screen would be three additional bars for showing you what each step of the installation was doing. So a bar for disk usage, etc. That was far more informational then just one bar with or without an ETA displayed.
(Windows 95/98 era).

@@nedmurry A point for epic games. They just gotta compress their files like steam does because i dont want to download 30 fricking gigabytes just to make games if i fan just downloaded 3gb instead from Unity
While it's not quite similar, Minecraft's Forge Mod Loader also tells you what it's doing; specifically, it has multiple progress bars, in increasing levels of detail, each with a step count. One for the main 7 or so steps of loading, then one for what it's doing within that step (i.e. loading a specific mod), then a third for what it's doing within that (i.e. loading individual textures).

Editing can do magic.
@@gabormiklay9209 buuuuut it’s a one take, so there’s no cuts...
The worst kind of progress bars are the ones that roll in a circle infinitely and it doesn't really mean anything. Sometimes the installation process freezes forever but the animation is still going.
That's not a progress bar, it's just a dumb animation. Still better than nothing, but not by much.
I believe the term for that is "Spinner". Ideally they should be used for tasks that only take a few seconds, because displaying a whole progress bar for something so short wouldn't be worth it.
if you see it on mobile games it usually just means your internet connection fell.
@@hoodiesticks Actually, the point of them is to indicate a task that will take an indefinite amount of time, e.g. when you're downloading a file that you don't know the total size of.
they're there so you can tell whether or not the application has frozen and/or stopped working
I am a computer security expert and you make a very good point about smooth progress bars representing something potentially malicious. Good stuff!
I found this very interesting. My job is a performance test analyst, and we often find that performance issues in software is not the software itself, but the users perceptions of it. Have a user wait for something to happen with nothing going on, instant 'its running slow' report. Add a spinner, progress bar, literally any user cue that something is still happening and they'll be more tolerant. The software could actually be slower because it has to deal with updating the screen as well as the job it's trying to do, but users will be happy about it.
The bar: *goes to 99% instantly*
Also the bar:
*Takes 5 hours to finish*

I'm sorry to inform you that sometimes the progress bars are explicitly coded to keep moving continuously at least a bit even when no job was completed since the "last big jump" of the progress bar. The "big jumps" are often when something has actually completed.
The one thing that should never ever ever be displayed on a PC is "100% complete. Please wait"

@@bosselotiscanon Ha! not gonna lie, that was actually fantastic 😆
My favorite memory of a loading bar (or technically a "time remaining" counter) was one time downloading/installing a game on Steam. It was maybe 80% of the way when I noticed the download speed was slowing down significantly, and so the remaining time predicted went up from 3 minutes to 4, 5, 6, 7, and kept climbing. 30 minutes, hours, then days, then weeks, then months, and finally was all the way up to 1 year of predicted time remaining. A moment later it finished and was ready to play.
Personally my favourite kind of progress bar is when there's two progress bars: the top one showing the progress of the overall process, and the bottom showing the progress of each individual task. That lets you actually see why some bits take longer, and in my opinion gives you a better approximation of the time left.
Loved that in older installers. Very informative and reassuring!
And in some cases help you with troubleshooting if somerhing crashes while loading :D
Thats good because you can actually see what is or isn't happening.
The only specific program I know that does that is WinRar while unpacking
@@derdarkl2890 As opposed to things like Limewire (remember Limewire?), whose loading screen had "steps" like "Scouring New York City for limes..." Which maybe the developers knew what it was actually doing at that point for debugging, but it means nothing to anyone else.

This video outro is a piece of art
I’ve been a software developer for decades and I still find myself trying to explain to people that the progress bar shows how much of all the tasks the program needs to perform have been done, not how much time it’s going to take to do those tasks
Since things have gone largely internet based (which can be a total crapshoot), progress bars have largely been replaced with spinning loading things because we developers have essentially given up on trying to give any predictions and just want to let the user know “we’re still doing something, please continue wait”
Checkout lines at the supermarket ARE the real life progress bars. You think that they're only a couple of shoppers ahead of you remaining but then one of them spends eons on counting their coupons and/or "remembering" to get one more thing and disappearing into the aisles!
Did they have to take a boat to get to the isles?
or the cashier's shift ends suddenly
Exactly - and wondering whether to switch to a different checkout is like deciding whether to cancel the download and try again from a different server
All these things sound like problems from back in the "human cashier" days.
@21st Century Socialist Cannot happen here, because every scanned item needs to go into the weighing area before it lets you scan the next. But I agree, I take longer at the self-checkout than a trained cashier would take to mark my items. So the waiting time becomes an important factor when choosing between the two options.
I remember back in the 2000's , the bars had little reference and animation. So I would put my cursor lined up with the bar to see if it was moved.

If you have two machines, you can leave one to process, download or install in its own time while doing something productive on the other computer or device.
If you are building or fixing a computer, you may need a second one to display the PDF of the manual, or to search online for how to fix the broken one.
And if it's the whole network that is being fixed, then it's time to catch up on something offline, even if it's just making yourself a nice cup of tea.
I like the comparison of loading bars being like the queue to a movie or something, reflecting real world incremental improvements the typical user can understand at face value. But filling a glass with water is in itself a smoothly transitioning progress bar we watch in real time, and if it's chunky then you got other problems to worry about.
You always gotta love seeing

What does ETA mean?
@@0_- ETA stands for estimated time of arrival, in this case it’s the amount of time the computer thinks will take for something to download.

then its stuck at "Copying...." for hours

It took me three days to download all the updates for Gran Turismo 6 on PS3 - with a freakin' 300 Mbit/s connection. I was using the disc copy, I might add. Why? Because someone at Sony decided that the best way to deliver updates on that system was by having each individual update install separately. This is a minor annoyance with a game that has received its normal three to five patches over its lifespan, but with GT6, this meant installing 22 patches, one after the other, each of them at least hundreds of megabytes large on a system with a hard drive that would have been slow in 2006 and a processor that is fine in a supercomputer, but utterly incapable of quickly decompressing large amounts of data. And the system inevitably failed at installing some of these patches, even crashed during one over night download session, because it's from 2006 and Sony's engineers were taking crazy pills at the time, so I had to delete everything and restart again twice. Those three days were the successful installation run and don't include previous failed ones. Naturally, Sony's servers were also slow as hell, for some reason, which didn't make it any faster.
Let's just say the PS3 is the last Sony console I've ever bought. The game's great though and it was totally worth the effort, but holy hell, what a nightmare.
Tom Scott tells me things I didnt even know I really wanted to know
Loved the video! Thanks!
“it’ll still probably be wrong... just differently wrong!” is a perfect explanation of me going back to check my answers on a math test
Your comment is the reason why I like internet.
I like it when they include something like a "3/16 modules loaded" or scroll names of current operations in plain text ( more common on linux machines) its a much more tactile sense that the machine is continuing to work, and seems a little more reassuring.
And then the Everquest progressbar started telling things like 'Attaching beards to dwarves.'
I've seen a post about someone complaining that "Their apps (or website, I forgot) tooks forever to load" and the company decided to do nothing except adding words like "Processing File (abc)..." and "Rendering assets (123)..." under the bar.
The same customer said that the loading screen are now faster than before HAHAHA.
@@Hxrb One of the beauties of UX. Just add in something to look at and the program appears to be more responsive. It even works for people who knows how that trick.

Well done great job explaining it
really clear and interesting. Thanks!!
"Less than 1 minute remaining", Yes 1 Microsoft minute...
Love Microsoft Minutes. "23 Minutes remaining" means anything from 7 minutes to 32 hours.
@@dave0smeg ahh
Don't quote me on this, but I think that behaviour comes from the way caching is handled. Essentially, most OSs will take some RAM that's unused at the moment and use it to cache disk writes to make them faster or even save some write operations if the same thing is modified multiple times.
The Windows Explorer doesn't know about that and just hears from the OS that files are being written, but not whether they are written to RAM or the actual disk. But the developers of Explorer probably thought of that, so to be sure the Explorer will tell the OS to flush the cache, (i.e. tell it to write all cached from RAM to the disk) before closing the copy dialog. They just didn't think to make a progress bar for that or adjust the existing one.
1 minute later. "2 hours remaining"
5 minutes later. "Done."
Similar to The World. Dio's monologues that are supposed to be 7 seconds long can be anywhere from 10 seconds to 10 minutes.
"It will be differently wrong."
I'll use that when I don't want to admit when someone is more correct.
I use something similar in programming. If I can get a program that was failing to fail differently, then I've learned something.
Loved the joke at the end. You got me.
I’ve always wondered why this happened. Thanks!
Vista: "Estimating time remaining..."
*2 hours later*
Vista: "Estimating time remaining..."
Vista: "0 seconds remaining"
*Task finishes*
At least your task finished, legend says there are Vista computers out there that are still estimating the time remaining
haha funny because vista bad.. get it?
I think the disk can go faster but it'll take time to get to it's max speed at that current time
That particular issue is because the system is indexing files and it can take ages to do just that.
Ah yes, the Vista experience of everyone who've never used Vista.
how you managed to time this single uncut monologue and casually describe the exact length of the video is a subtle nod to the pre production behind these videos. Great job as always Tom and team!
I don't even understand how they managed to pull it off.
@@wariolandgoldpiramid they used very good estimate and then they can hide the few seconds of error behind edits.
Reminds me of Tim Minchin's Three Minute Song
The outro had some leeway when it cut out, also the endcard could be increased/reduced. Also practice
@@Josh-ui7nq yes the Tom loading screen could also have been cut out if really that close

I honestly knew what to expect and halfway through wondered why I even clicked this
When my torrent downloads shows _"63 years remaining"_ I'm like "great, I'll leave it downloading and come back when I'm 84." Ten minutes later: _" seeding"_
Always love it when that happens. One time I got like 500 bytes per second. It hurt, but at least the download wasn't completely stalled
Nothing worse than going back to check on the download and seeing that it's on 99% but all the seeders are gone😂
@@laurinneff4304 I always increase my seed ratio like 10-100x higher than my default limit when that happens, hoping to offset the ppl that just leech, and maybe ultimately bringing the speed a bit higher for later ppl
Heh is Bittorrent still a thing? Been years since I last saw these terms used :) Seeding! Had forgotten! And share ratio!
@@jaakkopontinen yep! it gets used for linux ISOs quite frequently
I think some progress bars are liars, like the ones with backwards-flowing animations that give the illusion of forward progress, or the ones that creep forward ever so slightly as if a page is still loading, even though the internet connection has clearly dropped. Grr/sigh.
Progress bars are NOT the problem. It is **dumb programmers** who can't calculate how long something will take because no one cares about performance anymore.
_Just throw more hardware at the problem!_ /s
The purpose of progress bars is to make the waiting time easier for you. They're not lying if they're advancing without making "progress", because the time left to wait is decreasing. Just my 2¢
how about when it rounds up to "100%" despite not being done?
No, 100% means done, not nearly done. I think rounding up is okay except it should cap at at 99% and only go to 100% as part of a finishing transition (if you want to waste the user's time with one).
@@crashdemons Yup, that's a perfect example of lazy programming! Rounding down to the nearest integer or (round down to 2 decimal places) would be clearer.
My favorite vague "progress bar" is probably tied between windows 95 copy dialog where pages move from one folder to another, and the cable box reboot saying "setting up".... "Getting close"..... "Almost there". Jk those are the worst. The best are when they say in a game for example, "lighting torches, sharpening swords, assembling the king's men etc."
Well that was quite informative, thank you for the video
Finally! A very accurate and relevant video!
“It said something about a bios being updated, I waited like five minutes but nothing changed, so I restarted the pc.”
This comment caused me physical pain.
That's why redundant firmware loaders were implemented as soon as flash memory became cheap enough to do so. The machine can checksum the primary firmware and, if it falls, load the secondary as a backup.
oh
oh god
no
please no
There was a big red "DO NOT TURN OFF" alert but I didn't turn it off, I just reset it
@@thenasadude6878 this caused even more physical pain.
I know you could easily just look at a timer but I was honestly more impressed at your 1:24 callout than the "this video has 10,646,282 views" video
It was done by 1) a good estimation of the script length with a few practice runs. 2) Leaving one cut at the intro to slide the body of the video up or down the timeline to have his callout match the timecode.
@@blaster-zy7xx Or there was just a clock next to the camera
Probably a teleprompter and a timer. And experience. And a few retakes.
And the nothingness at the end of the video. Just add the required amount of seconds needed to make the prediction accurate
Stopwatch and a buffer at the end of the video so the final length could be edited precisely.
LOVE the ending!!!
