Spacestategeschiedenis

Subprojecten

• Statelogger en dump van heatmaps (Juerd)
  • Source: https://github.com/revspace/statelogger
  • Draait op gateway vanuit /home/juerd/statelogger
  • statelogger draait elke minuut
  • create-heatmaps draait elk kwartier
• Importeren van oude space-states (Juerd, eightdot)
  • Bron 1: twitter (ca. 2010-01 - 2013-06)
  • Bron 2: irc-logs (ca. 2012-05 - 2018-17)
  • Ondanks diverse handmatige fixes klopt 't niet helemaal, maar goed genoeg voor bruikbare heatmaps.
• HTML/CSS van de heatmaps (f0x)
  • Work in progress

File format

• First 8 bytes (64 bit): unix time_t epoch time of first data point
• Subsequent data: one byte per minute, byte offset = 8 + floor((time() - $start_time) / 60)
  • ASCII '0': space was closed (or mostly closed)
  • ASCII '1': space was open (or mostly open)
  • ASCII '?': script did run but could not determine space state (not currently in use)
  • ASCII '\0' (NUL): space state was not recorded
  • Any other value: treat as '?'

Statelog na iets minder dan 18 uur loggen: (* = meer van hetzelfde)
