Does Primal handle markdown? ``` data = 42; ready.store(true, std::memory_order_release); ```
Reading “Beyond Democracy”… An alternative for France: instead of having a single elected government that changes every five years, we could have 18 stable governments, one for each region, each one with its own laws and its own taxes. Citizens would be free to choose which region they want to live in and which government they want to pay for. Competition between governments would improve the quality of the services provided to citizens. image

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?”
