I'm doing a Go training on January 10th 9:30am to 4pm. Here is roughly what I'm planning to cover.

This is a project driven hands on training, so we will be building a project to learn different Go concepts.

Project: a Key Value Database like etcd/consul and a CLI (using gRPC) to interact with it.

Prerequisite

Reference: RFC 2616 - HTTP Status Code Definitions

400 BAD REQUEST: The request was invalid or cannot be otherwise served. An accompanying error message will explain further. For security reasons, requests without authentication are considered invalid and will yield this response.
401 UNAUTHORIZED: The authentication credentials are missing, or if supplied are not valid or not sufficient to access the resource.
403 FORBIDDEN: The request has been refused. See the accompanying message for the specific reason (most likely for exceeding rate limit).
404 NOT FOUND: The URI requested is invalid or the resource requested does not exists.
406 NOT ACCEPTABLE: The request specified an invalid format.
