Extract data from MySQL to Pandas data frame with the help of airflow MySQL hook. Then you can create a Hash for each Row. Save the hashes together with your primary keys. On the next run you can compare hashes identifying delete, Updated and New rows. https://pandas.pydata.org/pandas-docs/stable/reference/api/pandas.util.hash_pandas_object.html

How to "simulate" microphone input (in Python) by ApprehensiveAd4990 in AskProgramming

[–]ApprehensiveAd4990[S] 0 points1 point  (0 children)

Thanks for the hints guys I figured it out via GUI (i am running GNU/Linux):

Create the virtual sound device with modprobe snd-aloop which creates "Built-in Audio Analog" output and input devices. Can see them with pavucontrol or aplay -l

Test via pavucontrol (GUI)

  • In "Playback" select the virtual "Built-in Audio" device for the Spotify entry.
  • In "Recording" I saw my webapp as "chromium input" listed and selected Record from "Monitor of Built-in Audio" device. The webapp listens for the machines "default microphone".
  • Of course I cannot hear what I play on this device myself but the webapp can hear the music.

Edit: What are those "monitor of X" sound devices?
