which sounds like a joke, but it really isn't. i love the inescapable physicality of computers.Permalink Look on archive.org

Rowhammer is my favourite recent fundamental security flaw in the foundations of how we've built computers. You can alter memory you're not supposed to be able to alter... by repeatedly setting (a lot; "hammering") some memory that happens to be physically next to it on the chip.Permalink Look on archive.org

the chips are built so small some electrons leak over the back wall. you can't escape the fact that that bit of memory is a real place on a tiny bit of specially treated silicon.Permalink Look on archive.org

the solution is to make it harder for code to know where its memory is, relative to the memory it wants to fuck with. which is a practical solution, even if it's not a philosophical one.Look on archive.org
