System Design Cheatsheet

Picking the right architecture = Picking the right battles + Managing trade-offs

User cases (description of sequences of events that, taken together, lead to a system doing something useful)
- Who is going to use it?
- How are they going to use it?

-# delete local tag '12345'
-git tag -d 12345
-# delete remote tag '12345' (eg, GitHub version too)
-git push origin :refs/tags/12345
-# alternative approach
-git push --delete origin tagName
-git tag -d tagName

	1) Create a branch with the tag
	git branch {tagname}-branch {tagname}
	git checkout {tagname}-branch

	2) Include the fix manually if it's just a change ....
	git add .
	git ci -m "Fix included"
	or cherry-pick the commit, whatever is easier
	git cherry-pick {num_commit}
