<h2 class="section-heading">What this tutorial is</h2>
<p class="section-sub">
A chapter-based, hands-on path to writing real eBPF programs in Rust
with <a href="https://aya-rs.dev/">Aya</a>. You build each program on
your Fedora 44 laptop, deploy it to a disposable Fedora 44 KVM virtual
machine (so a bad program never touches your working kernel), drive load
from Python 3.14 clients running in Podman, and watch traces, metrics,
and logs land in Grafana through OpenTelemetry. It assumes you have read
<em>The Rust Programming Language</em> — this is not a Rust tutorial.
All container images are UBI-based; all kernel tooling (bpftool, bpftrace,
bcc) comes from Fedora/Red&nbsp;Hat repositories.
A chapter-based, hands-on path through Linux systems programming for
developers who already program and want to understand what their code
asks of the kernel. Each chapter builds the same runnable example
idiomatically in <strong>C++23</strong>, <strong>Go</strong>, and
<strong>Rust</strong> — processes, files and I/O, memory, IPC,
networking, and concurrency, then debugging, containers, observability,
and low-latency work. Everything runs locally on Fedora 44 except what
genuinely needs root, kernel observation, or a second host — that runs in
a disposable KVM lab. eBPF appears as an observation toolkit
(bcc-tools, bpftrace, bpftool) aimed at your own programs; this is
systems programming, not kernel programming. All container images are
UBI-based and run rootless under Podman.
