Already happy with Supabase, Neon, Amazon RDS or DigitalOcean Managed Databases? Keep it! Point your Potions app at it and we'll check your server can reach it before the app is created. The docs walk through TLS and poolers too. potions.io/docs/external-dat… #ElixirLang

External Databases - Docs

Connect an app to a PostgreSQL database you run elsewhere, such as Supabase, Neon, DigitalOcean or Amazon RDS, and encrypt the connection.

Ever wondered what actually happens during a zero-downtime deploy? On Potions, your new release boots in an idle slot, migrations run while the old one keeps serving, and traffic only moves over once the health check passes. Learn more: potions.io/docs/zero-downtim… #ElixirLang

For years I kept hearing "Elixir is great, but I can't deploy my app." That shouldn't be the reason anyone gives up on Elixir, so I built Potions: push your Phoenix app to GitHub and it deploys to a server you own. potions.io/blog/why-i-built-… #ElixirLang

As promised, version 0.9 of my book is out now! 🚀 This release brings a major rewrite fixing data loss in the Binance WebSocket stream, plus even more opportunities to learn #elixirlang through practical, best-practice-driven examples💪 Hope you enjoy! elixircryptobot.com/

Replying to @kamilskowron
Hi Kamil, I really like your book. I’ve been working through it recently, but it seems Binance has updated their API, and starting from Chapter 2 the examples no longer run as written. It may be worth updating the code or version references when you have time. Thanks again.

All @dnsimple name servers are now running an @elixirlang codebase. After 12+ years, we’re no longer exclusively an #erlang shop. But make no mistake: we’re still very much an Erlang shop.

Hi Elixir friends, After 3 years building Hologram full-time (transpiles pure Elixir to JS, bringing it to the browser), I'm at a crossroads. Working 60+ hr weeks balancing contracts & dev isn't sustainable. Where we are & how you can help: hologram.page/blog/seeking-s… Even sharing helps 💜 #Hologram #Elixir #ElixirLang #BEAM #WebDev
