I just finished building “Cube”, a Docker workload orchestrator written from scratch in Go. Orchestrators are the cornerstone of cloud computing. They automate the deployment, scheduling, and scaling of computing tasks (containers) across a cluster of machines. Every professional Web application you use today almost certainly relies on an orchestrator.

The most famous (and complex) orchestrator is Kubernetes. Cube of course goes nowhere near the level of complexity of k8s. Still, Cube made me understand the fundamental building blocks behind such software (Managers, Workers, Schedulers, Scheduling algorithms, Storage, basic Telemetry etc.)

To write Cube, I went through the book of Tim Boring cover to cover. The book is a great read, even though quite a few bugs slipped through the cracks and fixing them was left as an exercise to the reader. All-in-all it turned out to be a great way to learn.

Here is the repository: https://github.com/hakilebara/cube

Today I learned I can get a lot more done while staying inside Vim. I realized that while watching a Tsoding stream.

Reading Man pages in Vim

I am using this plugin https://github.com/vim-utils/vim-man.

Accessing the terminal in Vim

Since its version 8.1 Vim supports running a terminal window.

For reasons I don’t understand my posts on Twitter are no longer visible to the public. They are visible here though: https://xcancel.com/hakilebara.

I have little hope that this will get fixed. This is as good an opportunity as any to leave this site. I intend to do most of my writing on this website starting from now.

No more arbitrary limitation on character count. No more ads. No more engagement bait. No more blatant disregard for content moderation.
