Broadcasts

Broadcasts are messages that the Android system and Android apps send when events occur that might affect the functionality of other apps. For example, the Android system sends an event when the system boots up, when power is connected or disconnected, and when headphones are connected or disconnected. Your Android app can also broadcast events, for example when new data is downloaded.

In general, broadcasts are messaging components used for communicating across apps when events of interest occur. There are two types of broadcasts:

• System broadcasts are delivered by the system.

OctoPrint: FilamentManager to SpoolManager conversion

This is a minimal sql query to extract the most important information of the FilamentManager OctoPrint Plugin's sqlite datbase file to a SpoolManager importable CSV file.

Steps:

1. The FilamentManager database file can be extracted from an OctoPrint backup (zip-)file. The path in the backup file shoud be basedir/data/filamentmanager/filament.db.
2. Use a tool like (DB Browser for SQLite)[https://sqlitebrowser.org/dl/] (or similar) to open the FilamentManager database file
3. Execute convert_filamentmanager_db_to_spoolmanager.sql and export the result as CSV.
4. Use the SpoolManager import function with the exported CSV (From OctoPrint settings).

# PlantUML has "a lot of issues" with graphviz greater 2.38.0 (screwed up layouts and more, check the official PlantUML site)
# so we need to get the old port file
# I tested this with Mac OS 10.15.6

# the update to 2.40.1 was done by this commit https://github.com/macports/macports-ports/commit/937422eaee9e592a79b631ee20cecdbbe33a7375, so the parent on the master is c11df6b3e4867171fff9438ba499e20f31b449e8

# uninstall the current version first - note this might break other things ;-)
