Been coding for some 25 years already, and this year I thought it was about time I start sharing knowledge instead of consuming it.
I focus mostly on C++, since that's what I use daily at work.
The last few months I've been creating articles about topics I've been dealing with at work. Mostly RPCs, Boost/Asio, etc.
Anyone interested in reading no-bs programming articles, go ahead. No ads. Just content, done with passion and love (And lots of wasted time).

Best ones so far (in my opinion), from oldest to newest:
Callstack markers (boost::asio::detail::call_stack)
This article explores callstack markers, and a few things they can help us with. Very similar to a helper class found in Asio/Boost Asio (boost::asio::detail::call_stack) . Ends with a self-contained custom implementation.
How strands work and why you should use them
This one focus on explaining the strand concept found in Asio/Boost Asio, and ends with a self-contained custom implementation. Uses the callstack markers class introduced in the previous one.
Portable C++ Timer Queue
This dissects a portable timer queue, and again ends with a self-contained custom implementation.
Modern C++ lightweight binary RPC framework without code generation
This one took me probably around 2 months to put together. Only a few hours here and there of course. It puts together a C++ RPC framework with a surprisingly simple API that doesn't need code generation. The framework has roots in something I started last year, but I pretty much refactored and improved the entire thing as I was writing the article.
I'm actively using this framework in my game, and it will be improved as I go. So the article will of course be out of sync with the source code repository soon enough.
