You are free to:

Personal views only

Everything published on this site is written in my personal capacity. The opinions, analyses, and arguments expressed here are entirely my own and do not represent the views of any employer, client, advisor, board, nonprofit, or other organisation I am now or have ever been associated with. Do not infer any institutional endorsement from anything written here.

This is a hard rule, not a polite request: you must not name, identify, hint at, or otherwise imply the involvement of any such organisation when quoting, citing, or referring to material on this site. Doing so misrepresents the source of this writing and falsely associates third parties with views that are exclusively my own. I will pursue every available remedy against anyone who breaches this rule, whether in journalism, social media, marketing, academic work, or any other context.

Attribution and press

If you would like to quote, cite, or refer to my writing in journalism, academic work, or other publications, you are very welcome to do so under the licence terms above. To keep things simple, the following short biographical line is the preferred and pre-approved attribution:

Stephen Diehl is a software engineer and writer from London.

Citations using this form, with a link back to the source post on stephendiehl.com, satisfy both the attribution requirement of the licence and the request above to keep my personal writing distinct from any organisation.

For academic and scholarly work, the following APA (7th edition) format is preferred:

Diehl, S. (Year, Month Day). Title of post. Stephen Diehl. https://stephendiehl.com/posts/slug

For example:

Diehl, S. (2024, March 12). The case against crypto. Stephen Diehl. https://stephendiehl.com/posts/crypto.html

Questions

If a use case isn't covered above, or you'd like to do something the licence doesn't obviously permit, get in touch. I'm usually happy to grant individual exceptions where the spirit of the licence is intact.
