# Disclaimer > [!abstract] The short version > These are working notes, published as they are written. They are not professional advice, they were drafted with AI assistance and reviewed by a human, and they may be wrong or out of date. Check anything you plan to rely on. **Effective 18 September 2026.** ## Who publishes this This site — **jeffs.link** and **notes.jeffslink.com** — is published by **Jeffs Link LLC**, doing business as **JKJRDev**, of Arlington, Virginia. It is Jeff's personal working vault: a journal and a reference library, published as plain notes. Corrections and questions: **[email protected]** ## What the business actually does JKJRDev **builds and renovates websites**. That is the work it charges for. There is no advisory service, no retainer for opinions, and nothing on this site is a paid engagement or a solicitation for one. (Jeff also walks dogs now and then. That has nothing to do with anything published here.) The notes are written by a marketing technology practitioner and student of hypermedia, sharing working knowledge. Read them as one developer's notes, because that is what they are. ## Not advice Everything here is **general information and commentary**. It is not legal, financial, medical, tax, or professional security advice, and reading it creates no client or advisory relationship of any kind. In particular, the security notes describe risks and general practice. They are **not an assessment of your systems**, not a compliance review, and not a substitute for a qualified professional who knows your situation. Decisions you make after reading are your own. ## Written with AI assistance Notes here are researched and drafted with AI tools and reviewed by a human before publishing. Where a claim carries weight, the note cites its source and the date it was checked. AI tools produce confident errors, including invented facts and invented citations. That is true of the tools used here. **Verify anything you intend to act on, using the sources cited.** If you find a mistake, write to the address above and it will be corrected or removed. ## Accuracy and currency Notes are dated, and many concern subjects that change quickly. Nothing here is maintained on a schedule. A note may be edited, superseded or deleted at any time without notice, and an old note may be wrong by the time you read it. ## No confidential or client information Nothing here identifies clients or their business. Examples drawn from real work are generalised so that no person or organisation can be identified. Nothing on this site should be read as describing any particular client engagement. ## Third-party names, links and quotations Product, company and author names are used for identification and commentary only. Their appearance here is not endorsement, affiliation or sponsorship, in either direction. External links are provided for reference. This site has no control over other sites and takes no responsibility for their content. Quotations from books, articles and documentation are short excerpts used for commentary and criticism, with attribution to the source. ## No warranty This site is provided **as is** and **as available**, without warranties of any kind, express or implied, including any implied warranty of merchantability, fitness for a particular purpose, accuracy, or non-infringement. There is no guarantee that the site will be available, error-free, or free of harmful components. ## Limitation of liability To the fullest extent permitted by law, Jeffs Link LLC and its principal are not liable for any loss or damage arising from the use of, or reliance on, this site or its contents, including indirect, incidental, consequential or punitive damages.

It is published through Obsidian Publish, whose hosting operates under its own terms and privacy practices.
