Problem

A lot of GitHub projects need to have pretty math formulas in READMEs, wikis or other markdown pages. The desired approach would be to just write inline LaTeX-style formulas like this:

$e^{i \pi} = -1$

Unfortunately, GitHub does not support inline formulas. The issue is tracked here.

How to use Nginx as a Reverse proxy for HTTPS and WSS - Self Signed Certificates and Trusted Certificates

FrdS > credit...

Introduction

Nginx is a web server, also works as a load balancer, and may help us a lot in security and routing terms, because when deploying our applications to a production environment, we don’t want to put ports on the url, and also the dns has to look like clean to our users, also for security reasons, we don’t want to show the port explicitly where the service is being run. Also, I decided to make this tutorial, because I was working on a cryptocurrency exchange platform in a freelancing job, and the frontend communicates with the relayer(backend that receives the user order's for exchanging Tokens/Crypto) by HTTPS and WSS. The HTTP it was for the general APIs and for posting new buy/sell orders, and the Websockets was for making a full-duplex communication for near realtime u
