One more thank you, now that we've had some sleep. Code BEAM Europe 2026 happened because these people got on stage and shared what they've built 💜 #CodeBEAM #Elixir

That's Code BEAM Europe 2026. Two days, two tracks, one Informal Zone, and an unusual amount of music for a programming conference. Thank you to Day 2's speakers 🧵 #CodeBEAM #Erlang

[Code BEAM @CodeBEAMio]

[Code BEAM @CodeBEAMio]

For years we've told each other to let it crash. @expede closes Code BEAM Europe 2026 on Track 1 with 'Let It Disconnect: A Local-First Future'.

#CodeBEAM #LocalFirst

[Code BEAM @CodeBEAMio]

Closing notes on Track 1 now. Stay seated: at 16:45 @expede gives the last talk of Code BEAM Europe 2026, 'Let It Disconnect: A Local-First Future'. #CodeBEAM

[Code BEAM @CodeBEAMio]

The Gleam Language Update, from the person who started Gleam: @louispilfold, Track 1, now. Whatever shipped this year, you're about to hear it first-hand.

#CodeBEAM #Gleam

[Code BEAM @CodeBEAMio]

"Let it crash" works, right up until it doesn't. Spoorthy Sridhara is on Track 2 with 'Self-Healing Systems and When They Fail'. Possibly the most honest title of the conference.

#CodeBEAM #OTP

[Code BEAM @CodeBEAMio]

Yesterday's talk was 'Don't Crash the BEAM'. Rustler's whole promise is the same idea, in Rust. Benedikt Reinartz (Statkraft) is on Track 1 with 'Rustler News and Road to 1.0'.

#CodeBEAM #Rust

[Code BEAM @CodeBEAMio]

Last Lightning Talks of the conference, in the Informal Zone right now ⚡ Not filmed, not streamed. If you're in the building, this is the room.

#CodeBEAM

[Code BEAM @CodeBEAMio]

Last coffee break of Code BEAM Europe 2026. Then: Benedikt Reinartz on Rustler's road to 1.0 (Track 1), Spoorthy Sridhara on when self-healing systems fail (Track 2), and Lightning Talks in the Informal Zone.

[Hideki Takase @takasehideki]

After all, that’s exactly what a session focused on devices should be like!! #論よりRUN (The RUN is mightier than the word)
We actually got to run our Giocci, so I’m sure you all experienced its value firsthand! #CodeBEAM #びよ〜ん

[Hideki Takase @takasehideki]

Thank you so much for attending our Informal Session!! #CodeBEAM #CodeBEAMEurope #びよ〜ん

Happening now at Code BEAM: Erlang's JIT on ARM32!

Luca Succi & @peerstr on bringing BeamAsm to embedded/IoT hardware, plus live GRiSP2 benchmarks. 

#CodeBEAM #Erlang #IoT

[Code BEAM @CodeBEAMio]

Elixir developers have had doctests for years. @garazdawi from the OTP team is on Track 1 with 'Exploring Doctests in Erlang'. Erlang catching up, or doing it differently?
