Welcome to Engineering

Episode 1

Where Did the Desktop Go?

LPI 1.1, 1.3, 2.1-2.2, 4.1: Linux distributions and the shell, open-source licensing, command structure and options, quoting, environment variables, and reading man / --help.

Episode 4

Please Stop Emailing Code

GH-900 basics and repositories: Git versus a hosting service, commits, branches, remotes, GitHub Flow, Markdown, and repository structure.

Episode 5

Your First Pull Request

GH-900 collaboration and projects: issues, pull requests, discussions, reviews, labels, milestones, project views, and resolving merge conflicts.

Episode 6

The Community Has Questions

GH-900 modern practices, security and community: hosted editors (Codespaces, dev containers, github.dev), repository visibility and roles, branch protection, a required status check, contribution files, and InnerSource vs open source.

Episode 7

The Integration Ticket

Engineering bridge: HTTP methods and status codes, request headers and bearer auth, keeping secrets out of URLs, retrying transient failures with a cap, SQL joins and the fan-out problem, GROUP BY and COUNT, and parsing JSON safely.

Episode 8

First Team Release

GitHub Foundations consolidation: the full issue -> branch -> review -> merge -> verify -> release flow, a release checklist and its residual risk, and rejecting a confident bad fix. Spirals Linux verification, Python, and the API/SQL bridge.
