Nginx & certbot on Unraid

Here's a guide to running an nginx reverse proxy on Unraid with a Let's Encrypt wildcard cert (which can cover the Unraid web gui too), using the official nginx and certbot Docker images.

Other options:

caddy — popular nginx alternative with built-in automatic Let's Encrypt
pomerium — all-in-one reverse proxy, SSL, and OAuth-based login (compare to Caddy Security)
nginx-certbot — parses your nginx configs and manages certbot for you (see the original version of this gist for a script to copy your cert to Unraid)
swag — used to be called letsencrypt; has other things in it like PHP & f

How to make a Release Android App debuggable

Let's say you want to access the application shared preferences in /data/data/com.mypackage.
You could try to run adb shell and then run-as com.mypackage ( or adb shell run-as com.mypackge ls /data/data/com.mypackage/shared_prefs), but on a production release app downloaded from an app store you're most likely to see:

run-as: Package 'com.mypackage' is not debuggable

	// Parse string initData from telegram.
	var data = HttpUtility.ParseQueryString(initData);

	// Put data in a alphabetically sorted dict.
	var dataDict = new SortedDictionary<string, string>(
	data.AllKeys.ToDictionary(x => x!, x => data[x]!),
	StringComparer.Ordinal);

	// Constant key to genrate secret key.
	var constantKey = "WebAppData";

	// Target state
	var tx = 0;
	var ty = 0;
	var scale = 1;

	function visualiseTargetState() {
	box.style.transform = `translate(${tx}px, ${ty}px) scale(${scale})`;
	}
