Review publishing standardsTools & calculators
Practical tools for everyday activities.
The solvers, generators, and helpers behind our puzzle sites reflect a wider interest in making useful software. Brian Hamilton also builds calculators for activities including brewing, aquarium keeping, gardening, and soapmaking.
Our 8 Toolbox websites bring that work together, each with tools for its own audience.
