Browser histories

Unless you are using Safari on OSX, most browsers will have some kind of free plugin that you can use to export the browser's history. So that's probably the easiest way. The harder way, which seems to be what Safari wants is a bit more hacky but it will also work for other browsers. Turns out that most of them, including Safari, have their history saved in some kind of sqlite database file somewhere in your home directory.

The OSX Finder cheats a little bit and doesn't show us all the files that actually exist on our drive. It tries to protect us from ourselves by hiding some system and application-specific files. You can work around this by either using the terminal (my preferred method) or by using the Cmd+Shft+G in Finder.

Once you locate the file containing the browser's history, copy it to make a backup just in case we screw up.

The difference between XYZ and TMS tiles and how to convert between them

Lots of tile-based maps use either the XYZ or TMS scheme. These are the maps that have tiles ending in /0/0/0.png or something. Sometimes if it's a script, it'll look like &z=0&y=0&x=0 instead. Anyway, these are usually maps in Spherical Mercator.

Good examples are OpenStreetMap, Google Maps, MapBox, MapQuest, etc. Lots of maps.

Most of those are in XYZ. The best documentation for that is slippy map tilenames on the OSM Wiki, and Klokan's Tiles a la Google.

	install termux from app store
	in termux:

	termux-change-repo
	* (choose main and bfsu)
	apt-install openssl-tool
	pkg install ffmpeg

	test if ffmpeg works by typing ffmpeg, you should see default ffmpeg output

	Convenient DeDRM Scripts
	-------------------------

	NOTE: read https://blog.quaintous.com/2021/02/16/remove-drm-from-ebooks/ to find out what this gist is good for.

	* ./init.sh: extracts Adobe Digital Editions private key and required files to DeDRM.
	* ./dedrm: removes DRM from given ebook (pdf/epub)

	If you are using this for the first time, make sure that you have authenticated your Adobe Digital Editions (ADE) and run './init.sh'. Import any DRM-protected file into ADE and run 'dedrm.sh':

	#!/usr/bin/env python

	from scipy.io import wavfile
	import os
	import numpy as np
	import argparse
	from tqdm import tqdm

	# Utility functions

	import os.path
	import re

	'''
	INSTRUCTIONS
	1. Create a file with the following code
	2. Put the file you want to convert into the same folder as it, and rename it to "py_file.py"
	3. Add a "#F" comment to any lines in the code which have a function call that doesn't assign anything (so no =),
	as the program cannot handle these convincingly
	4. Run the converter file

	REM Download ffmpeg from https://www.ffmpeg.org/download.html.
	REM Place ffmpeg.exe in the folder with the vob files

	REM Merge all vob files into one
	REM VTS_01_0.VOB is usually the menu which you may not want
	if exist VTS_01_7.VOB (
	copy /b VTS_01_1.VOB+VTS_01_2.VOB+VTS_01_3.VOB+VTS_01_4.VOB+VTS_01_5.VOB+VTS_01_6.VOB+VTS_01_7.VOB ConCat.vob
	) else if exist VTS_01_6.VOB (
	copy /b VTS_01_1.VOB+VTS_01_2.VOB+VTS_01_3.VOB+VTS_01_4.VOB+VTS_01_5.VOB+VTS_01_6.VOB ConCat.vob
