C foundations: under the hood

Now that you have built apps, go one level down to see what happens inside the machine: C, pointers and memory, data structures and sorting. Harder than Python, but it explains why everything you built works.

OverviewNow that you have built and shipped your first apps, you go under the hood: how the system, the shell and containers work inside, then C with its pointers, dynamic memory, data structures and sorting.
Computer Systems, the Shell, and DockerA bridge before C: what happens behind any program you run, from files, permissions and the shell to processes and memory, and how containers isolate the runtime.
First Steps in the C LanguageFrom high-level interpreted languages to compiled C, close to the hardware, where you really start to understand what happens when a program runs.
