Linux from the ground up: the boot process, the shell, files & permissions, users & groups, processes, networking, package management, LVM and the C build process.

Version control end to end — what Git is versus GitHub, installing and configuring it, the everyday workflow, Git LFS for big files, and a scenarios cheat sheet.

Infrastructure as Code with Ansible: inventory, the config file, ad-hoc commands, playbooks, variable precedence, loops, conditionals, vault, handlers and custom roles.

Containers from setup to internals: images and the Dockerfile, environment variables, CMD vs ENTRYPOINT, networking, storage, Compose, registries and the engine.

Getting started with the Raspberry Pi and talking to hardware — the entry point into Embedded Linux.

Emulation vs. virtualization, and building minimal Linux systems in QEMU for both ARM and x86.

An introduction to the Yocto Project for building custom embedded Linux distributions.

From-scratch C systems training: filesystems and permissions, the build process, fork() and a hand-built shell, Unix utility clones, memory allocation, static/dynamic linking, OOP patterns in C, FreeRTOS concepts, and building a minimal Linux distro.

A dedicated track for production-ready custom shell scripts: IDE auto-updating, full system update automation, Google Meet CLI launcher, video duration calculator, smart file renaming with undo, and meeting downloaders.

Day-to-day Linux desktop tooling: system update automation, Distrobox/AUR, hibernate, a practical Git workflow, GRUB/swap/zram tuning, GNOME customization, and small CLI utilities.
