Free public beta until December 4, 2026: every course is open, no card needed. After that, the first chapter of each course stays free and full access is a one-time $39 ($19 for up to 100 founding members chosen for helpful feedback). Your progress is kept. How the beta works

time window

A slice of time, such as one hour, over which readings are grouped and summarised.

A time window is an interval used to group points for aggregation; tumbling windows are fixed and non-overlapping, sliding windows overlap.

Examples

  • Grouping gh-a1's readings into clock hours puts a 10:20 reading into the 10:00 window, computed in SQLite as ts / 3600 * 3600.
