Contact Ry Walker

I read messages about essays and research published here, thoughtful corrections, founder and software-engineering questions, speaking or podcast invitations, and the projects listed on this site. For a factual correction, include the page URL, the passage in question, and a primary source when one is available.

For attribution or reuse questions, identify the exact essay, chart, quotation, or image you want to use and explain the intended context. Research pages are living documents, and well-supported corrections help keep them useful.

For a suspected security or privacy issue involving rywalker.com, put “Security” or “Privacy” in the subject line. Describe the affected URL, observed behavior, and safe reproduction steps, but do not include secrets, credentials, or unnecessary personal data. Please do not test against other people’s accounts or data.

There is no formal bug-bounty program, and sending a message does not guarantee a particular response time. You can also find me on GitHub, LinkedIn, and X.
