This was perhaps the most important lesson I learned from being a solo founder.
As the founder and CEO of a small business, you are the end of the line. There is no one else to think for you, or hold your hand. There’s no safety net.
This was a pretty interesting buggy scenario I found while reading the clang-tidy checks. If you’re writing a function that takes a forwarding reference (what looks like an rvalue reference, but whose type is a template argument), you need to be careful to not call
std::move on it. You need to make sure to call
std::forward instead. Otherwise, you might accidentally trigger a move on an object passed by a caller! This would be confusing, since their object would be moved from, and they never explicitly called
std::move on it.
I got bit by
unique_ptr when implementing a linked list today. You need to be careful to manually
unique_ptr before resetting or you might accidentally free the entire list. This comes up when doing insertions and stuff like that.
