Piskvor / extract_cookies.sh

Created November 9, 2022 14:27 — forked from hackerb9/extract_cookies.sh

Extract cookies.sqlite to cookies.txt for use in wget or curl.

	#!/bin/bash -e
	# extract_cookies.sh:
	#
	# Convert from Firefox's cookies.sqlite format to Netscape cookies,
	# which can then be used by wget and curl. (Why don't wget and curl
	# just use libsqlite if it's installed?)

	# USAGE:
	#
	# $ extract_cookies.sh > /tmp/cookies.txt

Piskvor / nearby-coordinates.sql

Created November 4, 2022 07:39 — forked from statickidz/nearby-coordinates.sql

Ordering with SQL by nearest latitude & longitude coordinates (MySQL & SQLite)

	---
	METHOD 1

	This should roughly sort the items on distance in MySQL, and should work in SQLite.
	If you need to sort them preciser, you could try using the Pythagorean theorem (a^2 + b^2 = c^2) to get the exact distance.
	---
	SELECT *
	FROM table
	ORDER BY ((lat-$user_lat)(lat-$user_lat)) + ((lng - $user_lng)(lng - $user_lng)) ASC
