Well played.

[@キラキラくりくり頭]

I don't understand what happened, all I know is that it was related to audio somehow. Basically, I unplugged a speaker from my PC (and it had no other audio output device connected) and it totally screwed my machine. Internet connectivity was completely gone. All "restore Windows" options wouldn't work.
I downloaded an install disc image at work to put onto a USB stick, but... Our computers at work won't allow us to copy stuff to USB. So I had to burn it to a CD and use an external DVD drive. But then there was some issue that I can't remember the details of - but it wouldn't read the disc. It took me a solid week to fix.
(And it's really bugging me that I can't remember the last problem/solution)
But now I make sure that there's ALWAYS some headphones plugged into my computer so that it'll have at least one audio output device.

Actually, the use of a blue screen predates computer era, back to the TV broadcast era. (I was there). It was standard practice to display all blue screen to indicate a faulty video feed. Every colour screen (then) was a cathode ray tube. Every tube had 3 “guns” streaming electrons beams through a vacuum to strike the screen array of pixels, made up of red, blue and green glowing material. It was arranged that a loss of the incoming video drive signal to the CRT would turn on only the “blue gun”. This alerted instantly “the humans”, that the video feed to that screen had failed. Just image the frenzy in the video control room at a broadcasting station when all 12 display monitors turn blue during a live show... There was no Googling for help info in those days!

[@machinerin151]

Pretty funny how in Linux drivers are almost all in the kernel and very few kernel panics ever happen...

[@robertekis2450]

@@machinerin151 Oh, the drivers ran at the same priority (ring 0) for both OS's. As you say, the drivers were just built into the kernel on Linux and dynamically loaded for Windows (which I preferred). I think the main difference in Linux having fewer panics was because it has support for far fewer devices (remember how little wireless networking support there was and still is?). Also, I guess there was better testing for releases, although I remember Windows driver testing was pretty rigorous too, but users could opt to allow non-Windows Certified drivers if they wanted. So, Windows couldn't be blamed for all the Blue Screens :).

[@dylanh333]

​@@machinerin151 That's because those drivers are almost always developed, maintained, and tested by the Linux kernel developers, rather than 3rd parties doing this on their own.
You compare that with Windows, where Marvell might write a driver for their latest WiFi chip completely on their own, with its own bugs, and if it crashes, it takes the whole OS down with it.
Linux also doesn't have a stable driver API or ABI, so each new version (even minor versions) could introduce changes that require a whole bunch of drivers to be updated to support that version. For official drivers maintained by the Linux kernel team, part of their effort with releasing a new version is updating all the driver code to support the API changes in that version. For 3rd party drivers, they simply stop working with the new version, until the 3rd party developer adapts it to work with the newest changes to the API and ABI.
Personally, I wish Linux had a stable driver API and ABI the way Windows does, even if it reduced the incentive for companies to open source and "upstream" their drivers so that they could be maintained as part of the Linux kernel.
The biggest reason I want this is because in the smartphone space, companies like Qualcomm decide to (1) write their own drivers and not upstream them; and (2) instead of letting their drivers get broken by the next kernel version, they simply only support that one kernel version, and you end up with a device and chipset that's stuck on an ancient version of the Linux kernel for its entire lifespan.
Similarly, you might buy a cheap 10Gbps network card with some obscure controller, and it ships with a CD rom with the source code for the drivers for it, as it doesn't have upstream support. You might then go to compile that code into a kernel module, only for it to fail because it uses a deprecated function that was removed in the latest version of the Linux kernel you're on. Trust me, that's not a fun scenario to be in.

while not all, for sure, many 'win' key short cuts predate the win key. Crtl+esc does the same thing. I've gotten used to using crtl+esc instead of the win key because I keep the win key switched off on my keyboard to keep from accidentally hitting it while playing games. Also comes in handy if you're using an old model M. Shift+f10 is the menu key.

@@SodAlmighty No, a decade earlier, I just appreciate the best keyboard ever made. And as said in my post 2 months ago, I turn off the win key on my current keyboard (it has a switch for this) so that it is not accidentally pressed while in a game, causing the start menu to pop up and pull you out of said game. The actual shortcuts also come in handy when writing scrips, and also are very useful for disabled folk. today's standard 104 key keyboard still only has the same 101 unique keys from the point of view of the computer, with the extra keys internally just being sent as a combination of the needed keys.

A switch to disable the Windows key sounds very useful, but that's no reason to keep it disabled when you're not gaming.

Last time it happened to me, it was a faulty RAM. It took me ages to identify, as I first thought it was a faulty GC driver. It was only when I started to pull out parts of the computer (a little bit out of sheer spite) that it eventually stopped.

I know this video is old, but I used to have a $50 used NT 4.0 machine in my room as a child in the 00s, and it worked perfectly at almost anything I needed it to do. It was incredibly reliable for my writing and I still have the Seanix keyboard on my wall as decor. My only other computer option at the time was a late 90s Compaq Deskpro running Windows ME, which, was very BSOD-prone. We used that until 2006 because XP just outright refused to install on it. Then we got Vista. You can see my track record with real winners for operating systems here! I actually liked Vista a lot, after I took the bloat away from it... I got 7 when it released because it was so well regarded, despite Vista having stuff I really liked about it. I'm on 10 now and satisfied with it. What do you think about Windows adding the Copilot key and eliminating left CTRL entirely unless you remap it manually for W11? What's your favourite OS to use? And, finally, why was Windows ME so error-filled? Have a great early morning :)

You talked about moving the video drivers into the kernel. If my declining memory serves, this happened on build 1109 which was a Thursday (I'm more certain about the day of the week then the build number). To really put things into perspective, at the time there were 8 machines that built NT and I think we still just had the three release servers each with two 9GB hard drives.

[@DustinRodriguez1_0]

Hehe, when talking about Gates' reaction to the on-stage Win98 BSOD and him smiling... well, he was an actual developer himself. He knows as well as any of us that, really, it's just amazing anything ever works at all, not that it breaks. People don't give computers and software enough credit. Where else in the entire history of humanity have we built something with, say, a billion switches, flipping a few billion times per second, packed into a square inch of space, where one single mis-timed flip can cascade to total failure of the entire system, and the primary way it is worked with is through a dozen layers of abstractions? It's like repairing a car the size of a flea. While it's on the moon. With moon-length chopsticks. And we make it WORK sometimes? Frankly baffling. Especially when you're talking about operating systems and saying 'oh, and other people are going to write code which runs on the system at the same time, in the same memory, on the same hardware, and you both have to coexist without killing each other'.
I just recently was plagued with some BSODs on Windows 10 Pro. I've been using PCs since 1990, starting with MS-DOS 5.0. I've been through a lot of systems. This is the first time, however, that some RAM just spontaneously... went bad. No idea what happened to it, the system would boot and run OK for days then boom, BSOD. Memtest immediately failed on it. I figured out which sticks they were, and they were a kit I'd installed about 2 years ago. Had run just fine (and passed all memtests after install, I value stability above all else and always do stability tests after major hardware upgrades like that, adding 32GB more RAM) for those 2 years, then just started throwing failures. Memory check succeeded when they were removed and I was able to get them replaced under warranty and am back to 64GB but still feeling surprised such a thing just randomly happened.

[@drtaverner]

Yeah, computers are an amazing juggling act/magic show that looks easy to the end user/audience.
Consider that they cannot faithfully recreate music from the C64 because of "undocumented implementation" of the SID chip. Trans. "We made it work but damned if we know how." To me, that sums up so much. "Got it working, do not touch anything, no, it shouldn't, but it compiles consistantly so..."

[@cerulity32k]

Yeah. We literally put lightning into some sand and made it think. Give it some slack. I've been trying to do assembly and operating systems, but there are so many systems you need to remember and study to even have a glimpse of what you can do to talk to the machine, and it's absolutely terrifying.

[@Brahvim]

Forgot, or perhaps I never knew even _Sirs Gate was a developer._
Sad to know you had issues with memory - but hey, at least you had a BSOD to notify you! The last time the RAM on a machine I owned broke, I wasn't notified of it very well. Very lucky you were, Sir!
...yes, that machine used to have too many bluescreens anyway, but this incident occurred long after that issue had gone, after several Windows updates.
Anyway, have a good day, _and a good rest-of-your-life!_

[@xBINARYGODx]

@@Brahvim s/he didn't say they were notified easily - that said, bad ram tends to throw form a small pool of typical blu screen codes/given reasons, of course, some of that will overlap with a defective or not-currently-stable cpu core too.

[@hyoenmadan]

At the time Windows 95 (Chicago) was written, Gates wasn't a coder anymore... In fact, much like Jobs and ATARI, he had never wrote code again since his days with the BASIC interpreter. DOS has no code lines written by Gates (or Ballmer by extension), and ofc Windows neither has, both NT and the DOS based one. Just like Jobs, at time he was only doing corporate boss stuff.

I'm not a Windows expert, despite all my friends and relatives insisting that I am, but I have been solving problems since Win 3.1. My biggest frustration with Windows 10 is the most common error I get is "Something went wrong" ... period. It doesn't even tell you what program went wrong. Usually the first thing I do is go to the system logs but have quit bothering as I can never find anything dealing with an error. I really like 10, other than the fact so many utility shortcuts have been eliminated from the menus (now fixed with Open-Shell). I thought we had gotten rid of that issue with DOS. I have lots of problems remembering the keyboard commands.

I watched it POST and found out that this particular ATM was a crusty old 386 PC running OS/2 Warp. Pretty cool. What was also pretty cool was that it crashed before crediting my bank account, so I got that 20 dollars for free. Less cool was the fact that it never gave me my debit card back after it finished booting, and the bank ended up crediting my account that 20 dollars anyway, after I told them what happened to my card.
