SPECTRE AND MELTDOWN CANNOT BE PATCHED.
LOG4SHELL IS FOREVER.
@thegibson log4shell was funny because it was a fundamental broken design.
Similar to Java deserialisation in some way.
@vertigo @thegibson @millihertz Perhaps! But as tamsyn said: ""all modern CPUs have unfixable security flaws" no, really? well, perhaps it's time to question whether we made a colossal mistake 30 years ago when we all conspired to take the path of letting CPU speed inflate to such a massive multiple of memory speed"
@craigmaloney @noelle @thegibson @millihertz Single-issue, pipelined RISC with static branch prediction is OK and completely safe. (Static branch prediction basically assumes any backward branch is in a loop and takes the branch by default. Forward and indirect branches are treated normally; that is, they'll flush the pipeline and instruction queue.)
A bunch of technomancers in the fediverse. This arcology is for all who wash up upon it's digital shore.
