Note

I’ve written a newer optimized 2026 version of this guide with a faster setup using Zinit + Starship and improved plugin loading.

This version avoids slow shell startups and works better with modern Zsh setups.

Oh my zsh.

Git Subtree Basics

If you hate git submodule, then you may want to give git subtree a try.

Background

When you want to use a subtree, you add the subtree to an existing repository where the subtree is a reference to another repository url and branch/tag. This add command adds all the code and files into the main repository locally; it's not just a reference to a remote repo.

When you stage and commit files for the main repo, it will add all of the remote files in the same operation. The subtree checkout will pull all the files in one pass, so there is no need to try and connect to another repo to get the portion of subtree files, because they were already included in the main repo.

Adding a subtree

Let's say you already have a git repository with at least one commit. You can add another repository into this respository like this:

Semantic Commit Messages

See how a minor change to your commit message style can make you a better programmer.

Format: <type>(<scope>): <subject>

<scope> is optional

API versioning for HTTP REST interfaces (best practices)

We at SCC Team (and at SUSE in general) are providing more and more APIs with the wonderful HTTP REST approach. APIs evolve over time, often unexpectedly — so it makes sense to get into some API versioning best practices right from the day 0. I was asked to join Crowbar guys' discussion to share my SCC experience with versioning APIs. This article is an attempt to formalize our solution and prepare it for a wider audience.

So, imagine you have different API consumers out of your area of control. Some of them definitely will lag behind the latest release.
