intro

This is a rough plan of the development internship program for 2024 -8 to 10 weeks program-. The intern need to be able to reason about the code, and be able to write tests (units and integration), then they should be able to contribute to the daily work with the team.

Week 0

In this week we spend some time to get familiar with the basics of linux, git, shell, and how to read the documentation

• https://www.youtube.com/playlist?list=PLyzOVJj3bHQuloKGG59rS43e29ro7I57J ( lect 1-7)
• Effective Shell: https://effective-shell.com
• Linux Intro/Essentials https://lym.readthedocs.io/en/latest/ (till Linux Services, package management (apt only), networking commands)
• Reading manpages of echo, env, cat, wc, head, tail, yes, true, false, tree

extra

Week 1

We get our feet with learning the fundamentals of Go, and start developing small utilities in Go.

• Go fundamentals gobyexample
• coreutils #105: echo, env, cat, wc, head, tail, yes, true, false, tree (use gobyexample to speed up things)
• build your own git https://leshenko.net/p/ugit/# (5 steps)

Week 2

We introduce you to the testing, writing unit tests, configuring github workflows.

• learn Go with tests
• INI Parser project with tests #21
• Github Workflows
• build your own git https://leshenko.net/p/ugit/# (5 steps)

Week 3

In this week we develop a small http service and we cover how to test it and how to build a client to consume its api

• Datetime server #144
• HTTP Service testing
• DateTime http client #145
• context package
• build your own git https://leshenko.net/p/ugit/# (5 steps)

Extra

• go101
• ultimatego

Week 4

In this week we get familiar with docker and docker compose, what they do, and how to build a docker image, and how to reduce its size. Then we go through REST API, Swagger, and Postman. and we will build a small client that consumes the pokemon Restful API service.
