Stefan’s Blog

(this post was written by hand btw - because I despise AI Slop rhythm, emojis and structure sooooo much) I was recently asked to give a short AI-Coding Workshop for another company, which is outside my usual work.

For my personal projects, I used to use Sentry-hosted, but it usually dropped some events if there were a bad bot.

In the end of March 2025, I had the honor to present at the Ruby Frankfurt meetup.

Insprired by a recent blog post of Bohidar Batsov I decided to simplify my Zshrc.

Recently, Hetzner announced the new S3-compatible storage service.

On 1st Jan 2025 B2B companies will be required to send invoices in a machine-readable format.

On a recent larger migration, we wanted to move our whole app, including the database to a new server.

In the past, I built several e-Mail processing features using Ruby that predate the official ActionMailbox - Such as: Bounce processing, e-mail notifications, newsletters, order confirmations, forwardings etc.

Packs is a code organization technique introduced by Shopify and Gusto.

To speed up our build and deployment time, we recently implemented test parallelization for our two biggest app.
