What's the right way to pass form element state to sibling/parent elements?
...nto it, it seems as if actions are used for everything. It's like this big mix of spaghetti code and impossible to understand, total disaster. State management might be good, but possibly severely misunderstood. Is it safe to assume that flux/redux should only be used for parts of state that need to...

The new syntax “= default” in C++11

...presents some concept that is in the business domain of the program. Don't mix those! A football team is a kind of team; it has a roster, a roster is a list of players. A roster is not a particular kind of list of players. A roster is a list of players. So make a property called Roster that is a Lis...

Enforce safety: checked exceptions (Maybe/Either), avoid mixing concepts (Word, Int, Address)
Good data structures (like zippers) can make some classes of testing needless, as they rule out e.g. out of bounds errors statically.
