Editorial policy

Original guides and references serve different purposes

The homepage presents original Diary Coding guides. The reference library contains articles from other publishers with attribution and source links. News is a source-reporting archive, including RSS excerpts and licensed articles; a reuse license does not mean we wrote or tested the source material. The reference library and News do not display ads.

Examples and testing claims

When an example is described as executed, the article should identify the environment, steps, expected results, and limits of verification. Hypothetical examples are presented as simulations. An educational example does not establish production security. Security guides are intended for systems you own or are explicitly authorized to test.

Sources and writing assistance

Official documentation and standards are linked so readers can check explanations. Some drafts, including the introductory cybersecurity series published in October 2026, were prepared with AI assistance. Writing assistance is not evidence that an example has been tested; that claim applies only where its environment and verification results are stated.

Curation and corrections

Automatic news publication has been stopped; new material requires editorial review before publication. We are reviewing the older collection in stages. Separating the archive does not mean all older articles have been reviewed. Substantive revisions are noted in the article; code changes should retain their version context and limitations.

Attribution and responsibility

Articles identify their author or source publisher. Source links and licensing information are retained for republished material. Send content, attribution, or republication-rights corrections through the contact page. Advertising applications do not determine an article's technical results or conclusions.
