How to Install PostgreSQL Using `cloud-init`

cloud-init allows customising and configuring deployed server instances on most popular cloud service providers easily without requiring the use of other related tools like Ansible. Since cloud-init is such a reliable tool, this brief write-up will document the exact steps and procedures to install and setup PostgreSQL on a Debian 12 (Bookworm) server instance.

	[Blender and Python] Generating a procedural solar system with Blender's Python API
	Mina Pêcheux - August 2021
	Email: [email protected]

	A very basic Blender script that creates a simplified solar system with a few
	planets around a sun, adds shaders computed on-the-fly and sets various animation
	curves on the objects to get random revolution speeds.

	This code is a simple example of how to instantiate objects for

	# revert the order of a dataframe
	from pyspark.sql import SparkSession
	import pyspark.sql.functions as f

	# create spark session
	spark = SparkSession.builder.appName('some name').getOrCreate()

	# create a frame
	df = spark.createDataFrame([('a',12), ('c',10), ('b',9)], ['col1', 'col2'])
	df.show()

	import mlflow

	# There are two ways to create parent/child runs in MLflow.

	# (1) The most common way is to use the fluent
	# mlflow.start_run API, passing nested=True:
	with mlflow.start_run():
	num_trials = 10
	mlflow.log_param("num_trials", num_trials)
	best_loss = 1e100

	import fiona
	import geopandas as gpd

	# Enable fiona driver
	gpd.io.file.fiona.drvsupport.supported_drivers['KML'] = 'rw'

	# Read file
	df = gpd.read_file(path, driver='KML')

	# Write file
