Episode notes
Developer Educators Need Practitioner Credibility
- Developer educators are most effective when they remain credible practitioners inside the same technical ecosystem.
- The role combines programming, direct teaching, curriculum design, and developing other engineers as teachers.
The Editor Is An Engineer’s Home Base
- Jane Street treats the editor as an engineer’s home base for code, review, version control, and collaboration.
- Integrating internal systems there preserves fast keyboard-driven transitions from reviewing code to changing it.
AI Makes Understanding The New Bottleneck
- AI may reduce code writing while increasing code reading, navigation, and verification.
- Jane Street uses editor telemetry to test this rather than relying on speculation about changing workflows.
