Good or bad practice? Initializing objects in getter
... it seems... according to my co-worker at least. We've been working on a small project together. The way I wrote the classes is (simplified example):
...
pull/push from multiple remote locations
...ote command:
git remote add alt alt-machine:/path/to/repo
To fetch from all the configured remotes and update tracking branches, but not merge into HEAD, do:
git remote update

a = foo && bar

What does tree-ish mean in Git?
...--------------------------------------------------
Identifiers #1-14 are all "commit-ish", because they all lead to commits, but
because commits also point to directory trees, they all ultimately lead to
(sub)directory tree objects, and can therefore also be used as "tree-ish".
#15 can also be us...
How to pass parameters correctly?
... Are there any best practices of how to send parameters in C++ because I really find it, let's say, not trivial
