  • Not the case at all. Remember, biology is way more complicated than you think. As a starter, there is chromosomal and hormonal sex. Chromosomal sex (X and Y chromosomes) generally determines hormonal sex. But… the gene that determines hormonal sex (SRY) can sometimes get knocked off the Y and onto the X. Or off the Y and onto nothing. Or a bunch of other things. And hormonal sex can get disrupted in a bunch of ways, so that you end up with people who are intersex or seem to be cis female until puberty when they grow a penis. Or who appear to be cis female until they have problems conceiving and find out they are XY but don’t have testosterone receptors. Or any of a thousand other things that make sex determination complicated.

    Biology is statistical not deterministic and with 7 billion people there are going to be a lot of edge cases.




  • Vapor locking is an interplay between a mechanical vacuum based fuel pump and carburetors that causes the engine to get starved of gas and stall out. It’s made worse at high altitude and particularly when ascending rapidly like driving up a high altitude pass such as Wolf Creek. If you’ve even needed to pop your ears several times while driving you’ve been in a situation where it could have happened.

    Back in the day, the fix when it happened was to stop the engine and wait for air pressure to equalize through the system, which generally took about 30 minutes. Of course, this was on the side of a narrow twisty mountain road and people would sometimes get impatient or not know what was going on and flood their engine in a panic.

    It’s pretty rare now due to electric fuels pumps and fuel injection.



  • It’s alway weird to me that even though Ubuntu has the largest Linux desktop market share, no one admits to using it.

    Anyway, I use Ubuntu because I was doing a lot of ROS development when I last built a machine, and getting ROS running properly on other distros can be a pain.
