A real-time, lock-free, multi-CPU flight recorder

Debugging complex, real-time, multi-CPU programs like HPVM, Tao3D or the software in the DxO ONE can be a real challenge. You need detailed information about what's going on, but at the same time, adding instrumentation, e.g. a big bunch of ad-hoc printf statements, can change the behavior of the program sufficiently to make the problem you are chasing … Continue reading A real-time, lock-free, multi-CPU flight recorder

I've not written on this blog for a long time. A talk in Mouans-Sartoux yesterday prompted me to write this rant about what I will (demonstrably) call bogus interpretations of quantum mechanics. Specifically the "dead and alive cat" myth. Schrödinger's cat One of the most iconic thought experiments used to explain quantum mechanics is called Schrödinger's … Continue reading The bogus “interpretations” of quantum mechanics
