The C++ threads are the libuv ones which do the asynchronous I/O (disk or network). The main event loop continues to execute after the dispatching the request to thread pool. It can accept more requests as it does not wait or sle...
What are the downsides to using Dependency Injection? [closed]

std::cout << "Hello World" << std::endl;
}
I have a dependency I want to extract out and inject - the text "Hello...

Conclusion
Java has never been able to fully replace C++ for systems programming at places such as Google, in part because performance can not be tuned to the same extend due to the lack of ability to control memory layout and usage (cache misses affect performance significantl...
