===== Storage =====

  * Folders, Memos and Blobs are represented on disk as "Shard" and have address produced by hashing their content. This allows deduplication and (in the future) search for content by hash
  * Folders and Memos have mandatory Name and Parent field that is used by apps for lookups
  * "Public" area is separated from from private storage and contains either hashes or blobs
  * Cache servers store additional data for each

==== Misc ====

  * [[https://maps.google.com/pluscodes/|plus codes]] for geolocation
