...pens a new page is allocated from anywhere in the filegroup (from either a mixed extent, for small tables or a non-empty uniform extent belonging to that object or a newly allocated uniform extent). This might not even be in the same file if the filegroup contains more than one.

Break a previous commit into multiple commits
... the commit, but leave the committed files in the index. You can also do a mixed reset by omitting --soft, depending on how close to the final result your initial commit is going to be. The only difference is whether you start with all the changes staged or with them all unstaged.

What is “entropy and information gain”?
...ss into the purest possible children nodes (ie: nodes that don't contain a mix of both male and female, rather pure nodes with only one class).

It's too hard to reason about "what other interfaces might be mixed into the eventual implementor", and allowing an interface method to be final would likely cause these problems (and they would blow up not on the person who wrote the interface, but on the poor user who tries to impleme...
