☁️ How I got off the cloud and migrated everything from AWS to a VPS in Hetzner

This is an opinionated handbook on how I migrated all my Rails apps off the cloud and into VPS.

This is how I manage real production loads for my Rails apps. It assumes:

Rails 7+
Ruby 3+
PostgreSQL
Ubuntu Server 24.04
Capistrano, Puma, Nginx

A Tour of Crossplane 1.14

Crossplane is an Open-Source project that enables management of almost anything in the Cloud via the Kubernetes API.

Crossplane version 1.14 released November 1, 2023, is one of the most consequential releases in the project's history.

While Composition Functions and Provider performance improvements are headline features, there are substantial updates across the project: from a focus on developer and operator experience, Upbound's code donation to the CNCF, to API maturation.

This Document was updated November 7, 2023.

A curated list of command-line utilities written in Rust

Note: I have moved this list to a proper repository. I'll leave this gist up, but it won't be updated. To submit an idea, open a PR on the repo.

Note that I have not tried all of these personally, and cannot and do not vouch for all of the tools listed here. In most cases, the descriptions here are copied directly from their code repos. Some may have been abandoned. Investigate before installing/using.

The ones I use regularly include: bat, dust, fd, fend, hyperfine, miniserve, ripgrep, just, cargo-audit and cargo-wipe.
