For C++, we've built Learn C++ Through Projects [0], which is a project-based C++ course.
We currently offer only one project to build a transport network monitor. It starts with some low-level topics (we use WebSockets to handle tens of thousands of network events) but a lot of code is also higher-level (we use the network events to create a routing engine) - so it may not be exactly a "systems programming" resource!
