My work requires us to have full-disk encryption, so these are the steps I use.
The basic idea is to create a LUKS-encrypted partition which is used as an LVM Physical Volume.
The GRUB boot partition isn't encrypted, but everything else is.
These steps tested and working on 22.04 (jammy) and 20.04 (focal).

This is a quick guide to install PostgreSQL 10 - tested on Ubuntu 16.04 but likely can be used for Ubuntu 14.04 and 17.04 as well, with one minor modification detailed below.
To make life simple, remove all other versions of Postgres. Obviously not required, but again, makes life simple.
dpkg -l | grep postgres
N.B. SQLAlchemy now incorporates all of this information in its documentation; I’m leaving this post here, but recommend referring to SQLAlchemy instead of these instructions.
pip or conda, for example:

Hopefully this will answer "How do I setup or start a Django project using REST Framework and ReactJS?"
This is a guide to show you step by step how this can be setup. If you just want to get started, use the cookiecuter I set up cookiecutter-django-reactjs. It basically is a fork of pydanny's cookiecutter, just added the front-end stuff :).
I created this because it was SUCH a pain in the ass setting up a project using all the latest technologies. After some research, I figured it out and have it working. The repo that implements this is located here. Feel free to use it as a boilerplate ;)
Main features:
| Development Phase: | |
| Step 1: Create Certificate .pem from Certificate .p12 | |
| Command: openssl pkcs12 -clcerts -nokeys -out apns-dev-cert.pem -in apns-dev-cert.p12 | |
| Step 2: Create Key .pem from Key .p12 | |
| Command : openssl pkcs12 -nocerts -out apns-dev-key.pem -in apns-dev-key.p12 | |
| Step 3: Optional (If you want to remove pass phrase asked in second step) | |
| Command : openssl rsa -in apns-dev-key.pem -out apns-dev-key-noenc.pem |
Because pointers can be ugh
To understand a pointer, let's review "regular" variables first. If you're familiar with a programming language without pointers like JavaScript, this is what you think when you hear "variable".
When declaring a variable by identifier (or name), the variable is synonymous with its value.
| // Run this in the F12 javascript console in chrome | |
| // if a redirect happens, the page will pause | |
| // this helps because chrome's network tab's | |
| // "preserve log" seems to technically preserve the log | |
| // but you can't actually LOOK at it... | |
| // also the "replay xhr" feature does not work after reload | |
| // even if you "preserve log". | |
