Setting Up
Prepare a Fedora 44 workstation for three toolchains, provision the two-VM KVM lab for anything privileged, and stand up the Podman LGTM observability stack — everything later chapters assume.
Outline
The full arc of this book — fourteen parts, forty-nine chapters, six programs that grow with you, three languages the whole way.
Prerequisites and toolchains
Prepare a Fedora 44 host for systems programming in C++23, Go, and Rust — pinned toolchains, one check script that verifies everything, and a first tri-language example that asks the kernel who you are.
The KVM lab
Provision two disposable Fedora KVM guests with cloud-init — an observation-first toolset, snapshot/revert discipline, and a deploy script whose output proves your code ran on the guest kernel, not yours.
The local observability stack
Stand up the Grafana LGTM all-in-one container with podman compose: OTLP ingest on :4318, Grafana on :3000, a curl-able trace smoke test through Tempo, and the gateway rule that lets lab VMs reach the stack.
