A curated set of introductory resources for independent research, trustworthy workflows and confident use of technology.

A practical methods library

Starting points for open-source research, online security checks and reliable technical workflows. These notes are educational and are not legal advice or formal forensic findings.

OSINT · Images

Check whether a photograph has appeared elsewhere

For a suspicious listing or an image used out of context, compare several copies and record each original source.

  • Keep the original page URL.
  • Compare cropping and distinctive features.
  • Record dates and research limitations.
Method · Preservation

Document online material that may vanish

A screenshot alone cannot convey all the context. Timelines, page addresses and original files all matter.

  • Record URL, date, time and viewing context.
  • Preserve original files where possible.
  • Avoid altering source material.
Security · Email

Assess suspicious messages

The display name of a sender does not prove authenticity. Review links, the actual domain and technical headers if needed.

  • Do not open unexpected attachments.
  • Inspect full destinations before clicking.
  • Verify claims through another trusted channel.
OSINT · Domains

Understand a domain's history

Compare archived pages, historical DNS and available registry information, while distinguishing records from conclusions.

  • Separate registration and publication dates.
  • Check archive snapshot timestamps.
  • Describe uncertainty around ownership.
AI · Methodology

Use automation without losing oversight

AI can organise and summarise information, but factual checking and data protection still require explicit controls.

  • Define permitted actions.
  • Retain verifiable sources.
  • Test failure cases before launch.
Web · SEO

Build a search-friendly website

Useful content and solid technical foundations outperform artificial keyword repetition.

  • Give each page a clear purpose.
  • Align headings, summaries and schema markup.
  • Prioritise accessible, fast mobile pages.
