What are the best practices for catching and re-throwing exceptions?
... if it bubbles all the way up and needs to be logged, you can trace to the root exception thrown (walk the chain) so you still have all the debugging information that you need!
Don't simply catch and rethrow the same exception unless you need to do some post-processing. But a block like } catch (E...

How to merge YAML arrays?
...now which nested sequences to flatten (i.e. by knowing the "path" from the root
of the loaded data structure to the parent sequence), or that you recursively walk the loaded
data structure searching for nested arrays/lists and indiscriminately flatten all of them.
A better solution IMO would be to ...

Which kind of pointer do I use when?
...he existence of a tree implies the existence of its parent (or nullptr for root), so that uses a normal pointer. A binary tree (with value semantics) has sole ownership of its children, so those are std::unique_ptr.

Why should we NOT use sys.setdefaultencoding(“utf-8”) in a py script?

Example problem
While the setting of defaultencoding to UTF-8 isn't the root cause in the following example, it shows how problems are masked and how, when the input encoding changes, the code breaks in an unobvious way:

As you say, premature optimisation is the root of all evil, and (if possible) profiling really should always be used when optimising code. It can even help you determine the complexity of your algorithms.
