granu: audio generation on personal machine, pushes to s3
raspi: Wave Farm data collection units
server: data aggregation, analysis, and web-based playback

• scale is 60:1
• one minute becomes one second, etc.
• one second becomes 60hz, which is about musical time. (16ths at 120bpm is 32hz)

two types of data: continuous measurements, and discrete events, reflected in the model

'readings' just have a value. if the value repeats, we will assume it's constant. intended to be resampled. readings are taken every 5 minutes (-> 5 seconds)

with 'events', value is intensity. they also have a duration, and optionally a quality. events are quantized to every second (32nd note)

see crontab.smp for a list of sources and types

• What is the nature of remote monitoring? What can we know and not know through data?
• Rhythmanalysis vs surveillance
• Alternative relationship to data

• server is running
• MainStage loaded and set to soundflower
• MaxMSP loaded and set to soundflower, and signal vector size is correct
• run scheduler / set cron

• Browser and version
• time set

Requires housepy (for Python 2.X) and signal_processing and braid
