Token Bucket

This is an opinionated implementation of the Token Bucket algorithm for PostgreSQL.

Why?

I had several tasks, running on several intances, trying to query ChatGPT API at the same time.
I needed a solution to rate limit the number of queries made to OPENAI API, this information had to be available accross several services.
I only had one database (pg) available.

Virtual Hosts on nginx (CSC309)

When hosting our web applications, we often have one public IP address (i.e., an IP address visible to the outside world) using which we want to host multiple web apps. For example, one may wants to host three different web apps respectively for example1.com, example2.com, and example1.com/images on the same machine using a single IP address.

How can we do that? Well, the good news is Internet browsers

#Why rawData (reminder)

Because I don't want to have two requests to load one page (one for the squeleton, one for the datas).
So I want to embed the datas in my page on the first request to load them directly.

#How to use rawData

<div>
 {{the_datas}}
