This file is a log of everything I've encountered when trying to migrate a Node.js, Elastic Beanstalk application from the Amazon Linux platform to the Amazon Liunx 2 platform. Here's why you should migrate:

LTS support up to 2023 source
The Amazon Linux AMI's end-of-life is December, 2020 source
Amazon Linux 2 has some big package upgrades (GCC, Glibc, etc.)
Elastic Beanstalk also has some upgrades on top of Amazon Linux 2 (e.g. faster deploys)

Challenges

Disabling NPM install

Nespresso Expert machine Hack (Bluetooth)

Nespresso Expert machine has the Bluetooth ability which officially can be used only by Nespresso mobile app and it does not offer any API for 3rd party applications and services. Moreover, the Bluetooth services and characteristics are not documented and easy to use by the other Bluetooth libraries plus there is no documentation for the Bluetooth packets payload that need to be sent or received.

However, after searching a lot and sniffing the packets for a couple of days, I've been able to hack the machine and write the small nodejs application using noble and express to control and monitor the machine with Rest API exposed by express through Bluetooth connection. As I did this application for my ex-company and they are still using it for their demo I cannot share the code but I'm going to explain how it works.

_Thanks to this

Intro

This guide is specific to getting LND 0.5-beta and Bitcoind running on Ubuntu 16.04 LTS for mainnet. It is aging rapidly and includes steps not necessary on newer versions of LND. As of April 2021 it is very out of date for bitcoind. As of December 2021 it is outdated for LND too.

Original installation guide:

https://github.com/lightningnetwork/lnd/blob/master/docs/INSTALL.md

This guide is broken into the following sections:

Install bitcoind and set to start automatically
Install development tools and dependancies

Intro

the following guide is an updated install process based on the following, which needs some improvement still

This guide here is specific to getting lnd and bitcoind running on ubuntu 16.04 LTS for testnet.

It does not address mainnet, or using btcd, or neutrino.
