Former finance C++ dev writing about the merge of mining into the energy grid 🔋
C: how do we store a string? let’s use a char*, it’s efficient.
“But it’s dangerous! What it is passed around and outlives the original string?”
C++98: let’s use a std::string instead.
“But it’s expensive to copy and return”
C++11: move semantics.
“But it’s not backwards compatible with char * without a copy!”
C++17: std::string_view
“But it’s dangerous! What it is passed around and outlives the original string?”

It’s fun to think there was a time when the price of gold was flat. In Britain, the price was set by law to £4.25per troy ounce between 1821 and 1914.

C++ keeps evolving. It gets interesting new features roughly every 3 years.
The Bitcoin core code already uses some of the language features introduced in C++20 (2020)
