Course catalog
Every published course pairs book-style explanation with guided practice and state-backed proof checkpoints. Use the tracks below to choose a useful sequence instead of guessing from a flat list.
Available now
Together, the focused paths contain 801 lessons. Advanced practice and reference resources remain available when your role requires more depth.
Systems and access
Start with the terminal, add remote access and service operations, then move into shared-cluster scheduling.
Build terminal confidence from zero: navigate, inspect and change files, search text, route streams, manage permissions, recover safely, and prove results.
Complete 60 OpenSSH Essentials lessons in order. Use the optional library when your role needs deeper administration, trust, or networking controls.
Learn systemd by inspecting units, controlling services safely, reading logs, repairing failures, and handing off verified evidence.
Learn Slurm work from first request to verified history: inspect resources, submit jobs, diagnose waits and failures, build workflows, and recover safely.
Containers and cloud native
Build a progression through Docker, Compose, Kubernetes application operations, and Helm packaging.
Build practical Docker judgment through a focused Core Path. Find advanced engine operations, administration, and the legacy library in All Material.
Learn Docker Compose from zero: resolve an application model, operate projects safely, inspect live state, diagnose failures, and prove cleanup.
Start from zero, operate an application on an existing cluster, and prove each change through Kubernetes state.
Control values, render safely, operate release revisions, and troubleshoot Helm with evidence.
Infrastructure automation
Practice Terraform state and delivery alongside Ansible inventory, playbooks, and operational verification.
Learn Terraform by delivering safe, reviewable infrastructure changes from configuration to verified state.
Build practical Ansible judgment from inventory and playbooks through a focused Core Path. Find advanced engineering and controller operations in All Material.
Developer workflow
Learn Git from local changes through collaboration, recovery, and evidence-based troubleshooting.
Build reliable Git judgment from working tree to shared history: inspect state, stage and commit intentionally, branch, merge, recover, and collaborate safely.
HPC operations pathway
This suggested sequence starts with Linux command-line work, adds secure remote access, and then applies both skills to Slurm operations.
In development
Joining a waitlist requests one launch update. It does not start a purchase or promise a launch date.
Start with values, output, errors, and tests. Grow into files, APIs, classes, type hints, debugging, and a tested CLI capstone.
Practice values, functions, DOM updates, events, async work, fetch flows, state bugs, tests, and accessibility checks.
Work with tables, filters, joins, nulls, aggregates, windows, mutations, plans, transactions, dirty data, and report proof.
Test prompts, tools, retrieval, evaluations, and agent loops with visible inputs and outputs.
Practice host/device flow, kernels, grids, blocks, threads, memory transfers, coalescing, timing, shared memory, occupancy, races, streams, and profiling.
Practice HCAs, switches, ports, links, subnet manager, LIDs, routes, counters, degraded links, congestion, partitions, and incident reports.
Work through identity, networking, compute, cost, and recovery patterns across AWS, GCP, and Azure.
How it works
The lesson stays beside the workspace so the explanation and the evidence remain connected.
Read the symptoms, vocabulary, and exact question before making a change.
Run a command, edit a file, or inspect state in an isolated practice workspace.
Clear a proof checkpoint and connect the evidence to the decision that worked.
Questions
Yes. Every published course listed here has a free first chapter, and the free workspace opens without a credit card.
No installation is required to start a guided free chapter. Advanced lessons still explain the real tools and operational boundaries behind the skill.
