Dev Guides

Technical training you can run, not just read.

Each guide pairs a written lesson with hands-on labs that fail on purpose, an anchored assessment and the material to teach it to a room. Companion videos and short clips accompany the guides that have them.

  • Trace every call to its result
  • Diagnose a seeded failure

How every guide is built

Evidence before claims.

  1. 01

    Runnable

    Every lab is executed before publishing, with exact versions, commands and outputs recorded.

  2. 02

    Broken on purpose

    Each guide includes a seeded failure, its symptom, the diagnosis and how to verify the fix.

  3. 03

    Assessed

    Objectives map to a practical task and an anchored rubric, not a recall quiz.

  4. 04

    Teachable

    An instructor kit covers run of show, 12 and 100 learner formats, dry runs and clearance.
