Debloating Nox

Nox, despite being the most feature-filled Android emulator, has a lot of negativity surrounding it due to their antics when it comes to making income off of their program. It is known for running repeated advertisments in the background, calling home and passing along system information (outside of your Android instance) as well as a vast amount of potentially sensitive data in an encrypted payload back to their multitude of servers. With the following preventitive measures, we can stop a majority of this happening as well as greatly improve the overall performance.

Download and Install a fresh copy of Nox. The latest version is fine (for now). If you already have it installed, that is fine too. No need to reinstall.
Enable Root Mode on Nox by clicking the gear icon and then checking the Root Startup box.
Install a new Launcher from the Play Store. ANYTHING but Nox's default. I suggest [Nova Launcher](https://play.google.com/s

Developing an understanding of the FS2 Pull data type

In Pull[F, O, R], R is the return type. Pull represents a computation that emits some values on the Stream (of type O) and returns a new thing (R). In order to convert a Pull to a Stream, R must be Unit. This is because an FS2 Stream does not have the ability to terminate with a return value.

See here for the conversation

Stream[F, O] is monadic over O which are the output values emitted
Pull[F, O, R] is monadic over R which is used for stateful transformations

Cross instructions

These instructions cover:

building a cross toolchain
populating the new ROOT
making it chrootable using qemu-user to easily run "native" builds or tests (this is like a stage3 at the end)

You do not need to follow through to the end if you don't need a stage3-like root.

Set up the toolchain

Intro

One of Apexlab's strategic partners, Olvasoegylet.io sent us a request for a book catalog application. They would like to have a public collection of books for their customers. You are the chosen one who may write POC (proof of concept) purely back-end (Node) JavaScript (Typescript) application which they could use to provide data for their various mobile application eg.: Book Renter.

	dx = np.subtract.outer(x[:, 0], x[:, 0])
	dy = np.subtract.outer(x[:, 1], x[:, 1])
	dx[dx > (L / 2) 2] -= (L / 2) 2
	dy[dy > (L / 2) 2] -= (L / 2) 2
	pair_dist = dx 2 + dy 2
