# Rick Carlino

> Rick Carlino's personal blog and public notebook about software systems, open source, computing history, practical engineering, Korean language learning, and running.

This is a personal site. Opinions are Rick's own, not those of his employer. Blog posts are dated; older technical instructions may be out of date. Notes are working references and may be incomplete. Archived articles are labeled in their Markdown versions.

Public blog posts and notes have navigation-free Markdown versions at their HTML URL plus `.md` (for example, `/2026/introduction-to-decision-models.html.md`). Each Markdown page includes its canonical HTML source URL; use that URL when citing the content. Embedded videos are external content, and the site does not provide their transcripts.
