Comment on 10% of Firefox crashes are caused by bitflips

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.

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?

In practice preftct programs do exist, they just have to be small enough to do formal verification

Very ironic typo there

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.
