...ive you a hard time when they stubbornly refuse to match your domain motör_head.dev.local to your wildcard pattern *.dev.local. They will comply when you switch to motoer-head.dev.local.

How expensive is RTTI?
...ime if you can afford to do
if (typeid(a) == typeid(b)) {
B* ba = static_cast<B*>(&a);
etc;
}
instead of
B* ba = dynamic_cast<B*>(&a);
if (ba) {
etc;
}
The former involves only one comparison of std::type_info; the latter necessarily involves traversing an inheritanc...

How do I merge two dictionaries in a single expression in Python (taking union of dictionaries)?
...z = {**x, **y}
In Python 2, (or 3.4 or lower) write a function:
def merge_two_dicts(x, y):
z = x.copy() # start with x's keys and values
z.update(y) # modifies z with y's keys and values & returns None
return z
and now:
z = merge_two_dicts(x, y)
