	model instances as Task arguments.

	It "serializes" model instances to IDs and "deserializes" these IDs to model
	instances upon task execution.

	Serialized representation of a model instance is (sentinel, app_name, model_name, pk).

Allow Docker Container Access to Host's Postgres Database on linux (ubuntu)

You have to do 2 things in order to allow your container to access your host's postgresql database

Make your postgresql listen to an external ip address
Let this client ip (your docker container) access your postgresql database with a given user

Obs: By "Host" here I mean "the server where docker is running on".

Make your postgresql listen to an external ip address

Find your postgresql.conf (in case you don't know where it is)

$ sudo find / -type f -name postgresql.conf

Ultimate guide to low-latency osu on linux

this has been rewritten yet again as most workarounds aren't required anymore since wine 3+

example video of the final result: https://www.youtube.com/watch?v=zkqzQoeOGfU

with touchscreen: https://www.youtube.com/watch?v=GcIrlorWmaQ

performance is indistinguishable from windows. there might be a very slight ~25ms sound latency which is easily compensated with +25 local offset
