I guess you never have to shell into prod hosts if you only ever debug known unknowns.

Nothing says pragmatic like writing a bunch of conditionals over 20 LOC for an operation that should be <5 instructions.

Ah, rationalists: "it's the same game, they payouts are identical!". "After reducing two hypotheticals to 2x2 matrices with values in {-1, 0}, I don't see any difference between them. Debate me!".

Security researcher for a cloud provider that makes money by oversubscribing tenants thinks intra-core leaks are an important attack vector… to be fixed in microcode.

Branch prediction tables on recent Intel are partitioned by jump address bit 31. Using that for isolation is such a good hack

We often have to strengthen the induction hypothesis in recursive algorithms… but it sometimes pays to weaken and restore what was lost in post. In this case: what if we wanted TopK in any order?.

Given a stream of n integers, computing the sorted top K elements takes at least?. (I'm expecting a lot of people to get this wrong.).

I don't know about the takes on absurdly low p values < 1e-1000. ISTM the real interpretation is "the sampling isn't the dominant source of error, it's probably implementation errors or cosmic rays." And that's a useful result, because these error sources always lurk!.
