JensSpahnpasta10% of Firefox crashes are caused by bitflips
BjörnGuess Linus was right again to only use ECC RAM.
Retail4068Let’s spend a ton of extra money minimizing edge case crashing in a browser!!!
🙄
bruhduhYou enthusiasts server people, the dozens of you, are not the average consumer.
Who is talking about average consumers? We’re not trying to market something here.
Linus was. The answer is Linus. 🤦♂️
Avid AmoebaYes and? Us here are talking over a federated social platform. None of us are the average consumer.
Yeah, and was Linus saying this should only apply to enthusiasts? I know, it’s hard to keep track of the thread.
Buddy gtfo with this attitude. This isn’t Reddit.
Nah, fuck you and your inability to follow a thread 🤣
Moron. I replied to a specific and scooped component idiot.
Brilliant. This has nothing to do with what Linus said. And neither I nor the other commenter deserves this.
roofuskitYeah I can’t remember the last time my browser crashed. No way I’m upgrading all that hardware to avoid something that happens that seldom.
Probably not the use case you’d want to buy ECC for. I considered it for my homebuild because I figured I might process a lot of data at once, and I would appreciate the piece of mind… but I still decided no because I could get more ram for the same price if it were not ECC.
I don’t know about you, but I use my RAM for a lot more than a browser.
What nerd edge case do you want to talk about that is so important you need ECC?
Improved overall system stability and data accuracy? With error correction, you can also push performance farther, since you can tolerate a certain amount of errors, instead of needing to aim for 0% error rate.
Simple stuff like a calculator can be just as broken by a bitflip as more complex things. You woulndn’t want your calculator to say 1 + 1 = 2049.
If you want to rely on your computer, ECC RAM is required.
Exactly, one of the ‘nerd edge cases’ (as the now removed comment mentioned) is that I use ZFS on my NAS.
There’s lots of checksumming and encryption. Errors in that process are not acceptable and could potentially cause data loss. Since the one of the points of using ZFS is the enhanced data integrity, not using ECC means losing out on that guarantee.
Nobody fucking cares my man. Not important. Nobody in the regular world has ever been effected by not having ECC. You’re inventing edge cases that most cares about. Linus suffers from not understanding normal people.
Nobody in the regular world has ever been effected by not having ECC.
Based on the article, it looks like at least 10% of crashes are caused by not having ECC.
Linus suffers from not understanding normal people.
Well, you are demonstrating that you’re an expert people person so I’ll just have to take your word.
You can’s speak about not having frequent corruption of files when you are not using tools detecting it. I can guarantee you have plenty of already corrupt stuff on your hard drives. RAM bit flips do contribute to that.
You have bugs (leading to broken documents, something failing, freezes, crashes) in applications you use and part of them is not due to developer’s error, but due to uncorrected memory errors.
If you’d try using a filesystem like ZFS with checksumming and regular rescans, you’d see detected errors very often. Probably not corrected, because you’d not use mirroring to save space, dummy.
And if you were using ECC, you’d see messages about corrected memory errors in dmesg often enough.
At what% does this effect the average consumer. And additionally in a critical easy. Can you cite, literally one case, where the presence of ECC would have been critical beyond an occasional annoyance. 1.
The exact numbers for when it messes something up, but keeps running, are unknown and highly ubpredictable.
According to above post, about 10% of firefox crashes (more numbers found in the post) are caused by this stuff. It’s not unreasonable to say those crashes could’ve had the bitflip happen on content instead, changing maybe a character on the page or something.
Note that it’s not 10% of users, as that’s reslly hard to figure out. Someone with bad RAM will likely crash more often.
So no. You’re optimizing around an edge case and something users don’t give a fuck about. Got it. 👍
Linus would disagree with you there. It’s got a form of ECC, but it isn’t the same as server RAM ECC.
When ECC no longer costs a mortgage, I will look into upgrading.
douglasg14bI always love it when folks who don’t actually know what they’re talking about, comment like they do…
It’s not just the browser. This example is the browser, but it’s your entire system stability that is affected by random bit flips.
Blah blah blah blah. Explain to me, in in concrete terms how this affects the average consumer.
Jackass 🙄, you can’t.
There’s a jump instruction by an address read from RAM, a bit flip occurred so a condition “if friend greet else kill” worked as “if friend rape else kill”. Absolutely anything can happen, that wasn’t determined by program design flaws and errors. A digital computer is a deterministic system (sometimes there are intentional non-deterministic elements like analog-based RNGs), this is non-deterministic random changes of the state.
In concrete terms - things break without reason. A perfect program with no bugs, if such exists, will do random wrong things if bit flips occur. Clear enough?
Blah blah blah, made up use cases.
I don’t want to use the M-word or the T-word, but those “made up use cases” constitute every computer program in existence.
Sorry let me correct. Use cases that normal people give two fucks about.
Each and every one of them, moron. Everything you do on a computer every moment.
Guy, you can’t even separate your metal tracks on what people care about vs what is possible.
Point to me where you live in the spectrum.
People care about what they care about breaking in their hands and exploding into their faces.
ASD and BAD, probably also ADHD.
People also love to assume what they keep on their hard drives and memory sticks is somehow preserved over time and machine time. Bitflips and other physical effects onto your imagined perfect machine are why it’s not, and is as good or worse as what’s written on paper. A cat decides to piss onto your grandpa’s diary and there’s no more diary. Or humidity slowly eats it. With computers it’s even faster.
Oh, now we’re launching into hard drive degregation because firefox crashing isn’t actually enough to send normies into a rage?
Nobody but nerds optimizing for use cases for the. 01%.
In practice preftct programs do exist, they just have to be small enough to do formal verification
Very ironic typo there
