RNA Editing Is a Molecular Clock in Unmodified Human Cells

The biggest problem with Slack, by far, is that it is effectively ephemeral. An enormous amount of valuable content in Slack quickly becomes undiscoverable for all practical purposes. This creates significant challenges if history matters and this only gets worse as the number of people on it grows. In every organization I've participated in where Slack is the central "everything box", they had to invent parallel processes and systems so that things don't get lost in Slack.

Slack should be treated like the super-IRC that it is, it is poorly designed to be the nominal system of record that people try to use it as.

I don’t know what it is like today but that was not the case in the 1990s. I know people who got into San Jose State for STEM on a 2.xx GPA.

Most vaguely recent compilers will convert naively looping through bits into a native POPCOUNT instruction. The parallel bit count algorithm was not reliably detected until more recently and therefore would sometimes produce unoptimized code, though current versions of gcc/clang/msvc can all detect it now.

Also, pretty much every compiler for a very long time has supported __builtin_popcount or equivalent.

I don't think I've ever seen anyone deny the plausibility of the brain being wired differently than the body. What I believe the poster is referring to, and which I've seen in the media many times, is denial that physiological sex-linked characteristics are fully expressed even if doesn't match the one the brain is wired for. If brain wiring can mismatch physiology, it demonstrably is not determinative of the biology the brain is attached to in any meaningful way.

I understand the motivation for this denialism: most social institutions that segregate by sex are motivated by the practical effects of physiological sex-linked characteristics, brain wiring isn't a relevant criterion for determining "sex" for these purposes. It is currently impossible for the physiology to match the brain wiring in such case as a matter of science. Since the social institutions around sex segregation are widely viewed to exist for good reason, it motivates denial that physiological sex-linked characteristics actually exist for people that want to be segregated according to their brain-wiring sex.
