Corrections
Errors of fact are corrected at the top of the affected page with a dated note. Material corrections are listed below.
Flag a correction
If a guide, glossary entry, or note no longer matches production reality — or never did — please flag it. The fastest path is the email address on the subscribe page; please include the URL of the affected page, the specific claim, and the source of the correction.
Vendor-favourable or vendor-hostile content
No vendor — including the author's employer, disclosed on the about page — should be named, ranked, recommended, or criticised. If you spot anything that reads otherwise, that is a content bug and a correction priority.
