The Five Landscapes

What Tamil Poets Knew About the Earth, and What Satellites Show Us Now

Classical Tamil poets sorted the land into five landscapes: hills, forests, river plains, shore and dry country. This book reads those poems alongside fifty years of satellite records for India's far south.

Anabranch

A download manager that Claude can operate

It splits each file across parallel connections, picks up again after a dropped line and can run queues overnight. I built it for satellite scenes, DEMs and climate archives on FTP servers and data portals. Its MCP server lets Claude queue and schedule downloads and keep an eye on them for you.
