Essays and technical write-ups from a software practitioner covering maritime software, offline-first distributed systems, and the use of AI in engineering and training. Readers get case studies on synchronising ship-to-shore databases over satellite links and on auditing AI-generated e-learning courses.

Long-form investigative commentary on maritime regulation, submarine cables and geopolitics, built on shipping records and AIS vessel-tracking data. Readers get data-backed, sardonic analysis of waivers, defence contractors and naval standoffs that mainstream trade press tends to miss.

Beautiful Public Data is a newsletter by Jon Keegan that highlights visually interesting datasets from government agencies, with context on what each dataset contains and why it is striking. Each issue combines the source material with the writer's own observations, such as the anatomy of the Visible Human Project, WWII vehicle recognition guides, or boat names in NOAA vessel data.

Future Tides is a newsletter covering the Pacific Northwest maritime community, including port redevelopment, ferry electrification, waterfront parks and emerging marine technology. Recent issues mix reported news with links to regional coverage and event announcements such as walking tours of Lake Union.
