Episode SummaryIn the debut episode of Striae Origins, Stephen Lu traces the programming journey that laid the technical foundation for Striae, an open-source forensic annotation platform for firearms examiners. Before the crime lab, before the casework, before the courtroom -- there was a blinking cursor on a black screen.This episode walks through the languages, platforms, and hands-on experiences that shaped how Stephen thinks about software: from managing conventional memory in MS-DOS and writing a chatbot in BASIC, to designing a horse racing game on a TI-85 graphing calculator, learning C++ and hand-coding HTML in high school, building a Star Trek fan page on GeoCities, studying JavaScript in college, and modernizing the website for the California Association of Criminalists. Along the way, the episode dives into the histories of each technology -- who created them, why, and what made them matter. Get full access to Stephen's Ledger at ledger.stephenjlu.com/subscribe
