BEAM There, Done That is a podcast about building real systems with Elixir, Erlang, and the BEAM. We’ve built it before — distributed systems, fault‑tolerant services, event pipelines, real‑time apps, production nightmares, and the supervision trees that saved them. Each episode dives into practical lessons from shipping software on the BEAM: architecture decisions, scaling challenges, operational... more

Talking Points

Recent interactions between the hosts and their guests.

AI Found 5 CVEs in One Afternoon — The BEAM Security Wake-Up Call | Peter Ullrich & Jonathan Machen
Q: What is the proper process for reporting a vulnerability to maintainers when you discover something via AI tools?
Reach out to the maintainer following their security policy if available; if not, involve the CNA and provide support to coordinate disclosure, patches, and advisories.
Phoenix’s Next Evolution: Chris McCord Unveils the DurableServer
Q: What are the key criteria to decide when to use DurableServer versus a regular GenServer?
If you need global addressability or easy recovery from restarts without complex external state, DurableServer is a strong fit; otherwise, for node-local or ephemeral state, a regular GenServer remains the simpler choice.
Phoenix’s Next Evolution: Chris McCord Unveils the DurableServer
Q: Can you summarize what DurableServer is and what it isn't, for someone new to the idea?
DurableServer is a GenServer-like abstraction that adds durability, global addressability, and automatic rehydration while preserving the normal BEAM workflows; it is not about replacing GenServers entirely, but about offering optional, higher‑level capabilities when they fit a given use case.
Bridging Hardware-as-a-service with Elixir: Inside TV Labs’ Platform With Dave Lucia and Paulo Valente
Q: What are you most excited about for TV Labs in the near term?
They are focusing on expanding QA integrations, developer tooling, and AI/LLM-driven workflows, plus deeper cross-language interoperability and zero-copy data paths to improve efficiency.
Redistributing Our Systems. Erlang's Enduring Lessons for Local-First
Q: What are the trade-offs when using CRDTs for distributed data on devices?
CRDTs provide eventual consistency and offline operation but require careful UI and UX to communicate out-of-sync states and to manage the history and merge semantics, with trade-offs in complexity and storage.
