* blocklist/blacklist, I find blocklist clearer because it does what it says. Same for whitelist
* master/main, same as above, main describes it's function more accurately.
Regarding the genger wording, I have memories as a child where I was confused because for some reason, only the boys where adressed. Not thinking it through, I simply assumed that was intentional. And thus, if a teacher said 'boys, lets go that way!' I would be arguing with the girls since I thought they where not supposed to follow along.
Of course, this is not the case for ALL proposed inclusive language. I simply notice that most of the time, the inclusive alternative is a lot clearer.
