#ElixirLang (with Ash!) to expose an API called from Unity to update player balances. Events to Apache Pulsar (with Oban-based outbox pattern). Broadway to ingest them into Clickhouse for analytics.

I love #semaphoreci, it’s faster than GitHub actions thanks to the common setup between jobs. It’s very easy to have a mono repo and build specific docker images based on the pushed changes… and now it can even be self hosted

Sto pensando di fare un server minecraft con la cobbleverse e ci sarebbe spazio anche per un piccolo gruppetto di persone (probabilmente regge anche fino a 5/10 persone) #minecraft #cobblemon

What should Elixir developers call themselves? With Rust we have Rustaceans, with Python Pythonistas. With Elixir… Elixirians?

Debating if I should deploy my #ElixirLang project on AWS ec2 with autoscaling, on a Heztner VM or on my self-hosted mini-PCs cluster in my bedroom.

Multi-tenant storage 2nd iteration. Now I can upload files to S3 via my dashboard and keep a record on my DB of what has been uploaded for usage tracking. Together with an oban job to keep stuff in sync (storage<->db) if stuff happens.
Next steps: file previews & folders

Very first iteration of a multi-tenant object storage. You can only create and delete "buckets" for now. Using minio locally but it's a matter of changing 2 configs to swap S3 backends.
With #ash after hooks it is so simple to rollback everything if something goes wrong.

Second day using Claude Code. Most of the time I have to stop it and do adjustments and if I let it write too much code the quality goes to shit quickly. But it also feels less lonely to work on stuff. It's like that rubber duck technique but the duck can talk back and write code

I'm giving Claude Code a try and until now I had to stop it and and tell it to redo stuff in different ways 6 out of the 8 times... not a good start.

I want to make a multi-tenant object storage system like supabase storage for my project. All in #ElixirLang. For what I saw they have their S3 bucket and let users create their own buckets in it (in the end it's all just folders isn't it) with a cool dashboard on it.

Flutter has to completely redesign their UI system to match Apple's new "glass" aesthetic: github.com/flutter/flut...
Meanwhile, we're already running on iOS 26. Glass and all.

Finally got around the last chapter of the #ash book and added pubsub-based notifications! Tested it with org billing plan changes from Polar to trigger real-time alerts. So satisfying to see them pop up while I change stuff from another window. Love #ash <3

Since I've started this BaaS project I wanted to use Polar to handle billing stuff, but there is no sdk for #ElixirLang. So I made one and for the few api endpoints I use it works pretty well: github.com/giusdp/polarex

After a couple of months of developing my BaaS for gacha games, I noticed I was double querying everytime an user accessed the dashboard. And just like that I've cut in half database usage. #buildinpublic #ElixirLang
