Configuring a Socks Proxy in Splinter

I only found documentation regarding HTTP proxies on Splinter, but sometimes I just want to run ssh -D 1234 some-machine and get the SOCKS proxy on port 1234 to work with the Splinter browser. After many tests, I created these examples for Firefox and Chrome and all of them work.

For Web scraping tasks, sometimes having access to all the requests the browser made is a requirement, so I made examples for making this work with selenium-wire also. Since selenium-wire creates a proxy (so it can intercept requests between Selenium and the browser), the proxy configurations must be passed in a different way.

Agensgraph Docker

This is a Agensgraph Docker image based on the official PostgreSQL Docker image (not on Agensgraph's image, which has some issues). The current Agensgraph source is based on PostgreSQL 14.

Building

git clone https://github.com/turicas/agensgraph-docker.git

Python versions in Debian, Ubuntu, Fedora, AlmaLinux and Alpine Linux official Docker images

The table below was made by installing the package python3 in each Docker image and then running python --version (see the python-versions.sh for more details). Release and end of life dates were taken from:

	#!/usr/bin/env python3
	"""Find Portuguese sentences with different sentence_ids that match after normalization.

	Normalization: lowercase, drop commas and periods, collapse whitespace. A group is reported when two or more distinct
	sentence_ids share that key.

	Usage:

	Per-file strategy:
	1. Overwrite contents 3x (zeros, ones, random), writing at least MIN_OVERWRITE_BYTES even for small files
	2. Truncate to 0 bytes
	3. Rename to a random name (destroys original directory entry)
	4. Unlink
