Zero-dependency Python script to decode the Bluesky Firehose

This is a pure Python implementation of code necessary to decode the Bluesky Firehose's low-level binary data format.

It does not depend on any third-party libraries for decoding; we implement DAG_CBOR and CARv1 decoding ourselves.

To run this, install Astral's UV.

Then:

Setup tor proxy on Arch Linux

Copied from this article.

Installation

Install `tor`

     $ sudo pacman -S tor
     $ ## nyx provides a terminal status monitor for bandwidth usage, connection details and more.

$ sudo pacman -S nyx

Cleaning up haskell packages on Arch Linux

In Arch Linux, all haskell packages are dynamically linked. This can be a headache for the user, since it results in a large amount of haskell-* packages being installed on your system, and the possibility for version conflicts. A way around this is to not depend on pacman at all for haskell packages, but manually install them. In this document I explain how I switched from a lot of haskell packages installed with pacman, to a few manually installed packages.

Finding packages to uninstall

To determine which packages to uninstall (and replace), a few tools are useful:

pacman itself
pacgraph

	// Types for the result object with discriminated union
	type Success<T> = {
	data: T;
	error: null;
	};

	type Failure<E> = {
	data: null;
	error: E;
	};

	wordlist created from original 41G stash via:

	grep -rohP '(?<=:).*$' \| uniq > breachcompilation.txt

	Then, compressed with:

	7z a breachcompilation.txt.7z breachcompilation.txt

	Size:

	import Foundation
	import SwiftUI

	extension EnvironmentValues {
	public func value<T>(_: T.Type = T.self, forKey key: String) -> T? {
	guard let value = first(where: { name($0, equals: key) }) else {
	print("No EnvironmentValue with key '\(key)' found.")
	return nil
	}
