With ECC ram and resilient file systems
regular ECC can only protect against single bit flips though. If more than one happens to flip at the same time you're fricked
>If more than one happens to flip at the same time
That's about as likely to happen as getting struck by lightning then eaten by a shark while having a winning lottery ticket in your pocket.
ECC mainly.
You're not fricked if you accept that the machine stops on two bit errors.
Yes yes, we all saw that video in our "feed" or whatever on youtube too, I know you're excited to share what your parasocial friends told you with your other group of parasocial friends, but you're an idiot and an npc who doesn't understand just how moronic you really are.
Thanks for saying what we all thought.
> how do i keep falling for the same fake news bait posted around the internet for years by fricking Black folk and computer illiterates?
you're just fricking moron.
>Yes yes, we all saw that video in our "feed" or whatever on youtube too
and not a single word of it is true.
easy. you just lie.
probably hacked cartridge. it's not like these speedrunning organizations get gamers to submit dumps of the roms they're playing. it works on a completely "trust me bro" basis when it comes to real hardware. as long as they see you playing it on video that's all that counts.
>probably hacked cartridge
Now that you mention it... isn't it pretty trivial to hack a rom to manipulate some RNG to just make it appear as if you got really lucky? You'd just have to make sure there isn't some way to predict RNG results via gamestate or some shit.
What if he's just a cheater who came up with this bullshit?
Never happens.
how do they know it was le heccin space beam though?
because it totally wasn't a fed bit flipping attack, it's totally a beam, trust me bro
are you saying that xhe lied? that's transphobic
science!
Do you think he had his computer sitting in an x-ray machine? No other options really
new speedrun meta is getting more interesting
It's the most probable option since we're constantly getting blasted by gamma rays from the sun.
But maybe he has uranium on his desk as a speed run strat.
Depends where the bit flip happened
>if in ram
You need ECC ram, thank Intel for not having it in desktop pcs. "You don't need it bro."
>if in storage
A checksumming filesystem with parity.

You guys don't believe this right? You'd need to have really low IQ to actually believe that a space beam flipped the bits on some random guys video game.
actually it happens all the time, and only brainlets think it must be fake
I mean, you're getting pelted with them right now. Like, right now. Your DNA is being rewritten by cosmic rays with literally every breath.
Your body expends a massive amount of energy toward fixing these mutations so you don't just instantly get cancer.
People who call it unlikely are idiots, even if it isn't what caused the upwarp.
and I don't feel it, something like that cannot flip bits, moron
Happens occasionally, so it's not entirely impossible, but its very rare and older chips with thicker conductors inside are more resilient to it.
Ionizing particle? More like lyin'-ass article!
I'm not watching your video. Give it to me in text form or it simply doesn't exist to me.
The footage of the original assumed bit flip couldn't have been from an ionized particle, it was likely the fact that the runner had a faulty cartridge he had to move around, which is likely to flip many bits at once at the slightest of movement from the cartridge
>which is likely
tilting a cartridge or making a setup to test a simple cartridge contact is very easily replicable, just like goldeneye geddan glitch, so you should be able to replicate it.
I recall the video mentions that the aforementioned speedrunner did have, with certainty, a problematic cartridge.
How long before speedtrooners start sourcing ionizing isotopes to improve their times?
So if bits are likely to 'flip' so easily how the frick does any program manage to run?
Cosmic bit flips are extremely rare, and ECC RAM handles them regardless.
>extremely rare
if by rare you mean "happens several times a week or even day on every PC in the world" sure
one bit isn't usually enough to matter, cosmic rays aren't the only way to flip a bit, and there's loads of error correcting code
>if by rare you mean "happens several times a week or even day on every PC in the world" sure
no by rare I mean it likely never happened to any single person in this thread and likely never will
It has probably happened to everyone in this thread today on at least one of their devices.
It was one flip per 256 mb per month in the fricking 90s when transistors were a fraction of the density. It's only gotten EASIER to flip a bit with time. It will only continue to get easier.
DDR5 is basically ECC RAM, so it doesn't matter as much. But it will happen more.

>everything needs higher voltage to work
>has become easier for insignificant particles to flip bits
why are intel making me use over 1 volt if one electron is all I need?
Why don’t you go learn about semiconductors and what a particle can do to them and then you might understand.
nothing, if you weren't lying I wouldn't have to pay electricity bills for my computer use
>what is error correction
Where do you think those weird random bugs that happen only once and get fixed once you restart the program/computer happen?
I FREAKING LOVE SCIENCE
plastic apparently shields these type of radiation from space. or better yet you could make a underwater lead-roof bunker but then you'd be exposed to radioactive gasses and particles/stones beneath so the best thing to do is just get a fricking thick slab of plastic and put it on top of your PC case or storage devices.
Pretty sure it was a slightly tilted cartridge.
Yeah either a ultra rare coincidence happened that helped him achieve that or he cheated
>autistic giga-forevervirgin cheats
>"no-no-it was HEECIN SCIENCE!"
>omg omg
I don't know what the most disgusting part of the whole story is tbh.
Just don't count the run or mark it tool assisted. Who cares?
reboot your machine when it happens
sitx or rar/par
ZFS. Raid Z2. zpool scrub pool0. That will correct flipped bits as long as not too many bits per parity bits have been flipped.
just use a good filesystem + ECC if you really have autism about it
which fs
z
>test it with script at the same time
>wow lol works just like his speed run that's insane!!!
>ignore he cheated
>i didn't crash my car! a meteorite musta gone through it!
