Stateless is a lie

There is no such thing as stateless authentication

The big "make everything stateless" hype is just that: hype. Your server-side application code, should usually be stateless, because this makes your application more resilient to errors, easier to scale, and easier to reason about. But there are exceptions to even that, especially for stuff like video game servers.

Your services are almost always going to be stateful, and should be. If you have a database, files, or literally anything that affects the responses the server sends, then the service is not stateless.

So building "stateless" services is a lie. You shouldn't strive to make your services stateless, you should make sure you're putting your state in the correct place.

Where does my state go?

Estimation

This document is an attempt to pin down all the things you don't think about when quoting for a project, and hopefully provide a starting point for some kind of framework to make quoting, working and delivering small-medium jobs more predictable and less stressful.

Quoting

The hardest bit of any job, and lots of pitfalls

Estimating the work

  • the actual work of what you see on screen will only be a fraction of the work to do

A complete list of books, articles, blog posts, videos and neat pages that support Data Fundamentals (H), organised by Unit.

Formatting

If the resource is available online (legally) I have included a link to it. Each entry has symbols following it.

  • ⨕⨕⨕ indicates difficulty/depth, from ⨕ (easy to pick up intro, no background required) through ⨕⨕⨕⨕⨕ (graduate level textbook, maths heavy, expect equations)
  • ⭐ indicates a particularly recommended resource; 🌟 is a very strongly recommended resource and you should look at it.

FWIW: I (@Rondy) am not the author of the content presented here, which is an outline from Edmond Lau's book. I've just copy-pasted it from somewhere and saved as a personal gist, before it got popular on newsnews.ycombinator.com. I don't remember where exactly the original source is from and neither could find the author's name, so I cannot give him/her the proper credits.
