Ostler emails his brother in Latin for fun and enthusiasts maintain websites such as Circulus Latinus Interretialis (Internet Latin Circle), Grex Latine Loquentium (Flock of those Speaking Latin) and the connected online paper Ephemeris.
One of the lightest things you can carry is an app, and his favourite is the Photographer's Ephemeris, because it helps you plan the perfect outdoor shoot, with time-specific details about the position of the sun and the moon, such as when and where the moon is likely to rise over a particular hill.
