✓Senior Engineering Core Skill: Reducing ambiguity separates senior engineers from others through asking questions like what problem needs solving, who the user is, and what assumptions might be wrong before coding.
✓GitHub Migration Rationale: Zig moves to Codeberg citing GitHub's engineering decline, sluggish performance from bloated JavaScript frameworks, neglected Actions bugs, and aggressive Copilot pushing that violates no-LLM policies.
✓SSD Data Retention Risk: Consumer SSDs using TLC or QLC NAND flash lose data integrity after one year without power as electrical charges in transistors degrade, unlike magnetic hard drives with permanent storage.
