Anyone else go from “Phoenix is magic” to “wait… what is this macro actually doing?” 👀

New BEAM There, Done That episode with Adi Iyengar, who spent 3.5 years rebuilding Phoenix from scratch to understand the layers underneath.

defmodule MyFramework do

use Plug.Router

# accidentally reinvent Phoenix

end

Really good discussion on:

Plug as the real core of Phoenix
when metaprogramming helps vs hurts
old BEAM web-server history (Yaws, Mochiweb, Inets)
why coding agents still misunderstand Phoenix in 2026

Worth it if you’ve ever wanted to understand Phoenix beyond the generators.

Best enrichment tool for DACH contacts (including phone numbers)?

I’m looking for a good contact enrichment tool focused on the DACH region.

Most tools I tested have weak coverage for Germany/Austria/Switzerland, especially for direct phone numbers and mobile numbers.

Current setup:

Using Mailchimp
No CRM yet
Working mostly from CSV uploads
Want a weekly enrichment/update workflow

What tools are actually working well for DACH data quality?

Would especially appreciate recommendations for:

Phone/mobile enrichment
GDPR-safe providers
CSV + recurring enrichment workflows

Tried a few popular tools already but results have been pretty inconsistent.

Anyone here running Elixir + Rust in production?

New BEAM There, Done That episode with Florian Gilcher (Ferrous Systems) and Leandro Pereira (MDEx, BeaconCMS) dives into where Rust actually fits in Elixir systems — NIFs, ports, performance bottlenecks, and hybrid architectures.

case system do

:cpu_bound -> Rust

:distributed -> Elixir

:both -> "why not both?"

end

Good discussion on when to stay on the BEAM vs when Rust genuinely helps instead of just adding complexity.
