GopherCon Europe

The GopherCon Europe 2026 talks are up: www.youtube.com/playlist?lis... And tickets for GopherCon Europe + HeyAI 2027 are on sale. Berlin, 14-17 June 2027: gophercon.eu/tickets #gopherconEU #golang

I had a blast at @gopherconeu.bsky.social, great questions and great feedback. Often TamaGo feels magic at first, but makes total sense afterwards, many reacted this way and it is so humbling. I also added for the first time my thoughts on AI and what bare metal Go brings to the table.

@gopherconeu.bsky.social A timely reminder from Anderson Queiroz that we no nothing - without measuring!

Daniel Esteban built a fully functional 15× scale replica of our XIAO ESP32-C3 — 3D printed, wired up, running @tinygo.org. A real XIAO hides inside the giant USB-C port. At the @gopherconeu.bsky.social Tinygo hacksession today with @deadprogram.com Check out the full build 👉 tinyurl.com/5yutce5f

Last full „regular“ talk for the day at #gopherconEU: #Golang on the Dreamcast: Building a Runtime for 16 Megabytes by Panagiotis Georgiadis from Red Hat

Next up is Gili Kamma sharing tips and tricks for concurrency in #golang #gopherconEU

Not only a great deep dive into the garbage collector in #golang but an absolute masterclass in improv and creating images in the mind of the audience. Because who needs images showing up in their presentations. Not @alexrios.me! #gopherconEU

Back from lunch to Naoki Kuroda‘s talk on Building a SIMD csv parser in #golang 1.26 #gopherconEU

Shout out to @tinygo.org team member Patricio Whittingslow's amazing "lneto" network stack used by both TamaGo and TinyGo! #gopherconEU #golang #tinygo #tamago

Elliott Bouhana & Romain Mercadier from @datadoghq.com talk about Beyond #cgo - Fast FFI in the hot path #golang #gopherconEU

I definitely have opinions on this talk. Like, Opinions ™️ #gopherconeu

Now @andreabarisani.bsky.social about TamaGo here at @gopherconeu.bsky.social #gopherconEU #golang #embeddedGopher

Next up is Andrea Barisani talking about #tamaGo in his talk about the cross section of #golang embedded and cybersecurity #gopherconEU

Let’s welcome Cedric Namkat for his talk on error tracing in #golang #gopherconEU

Starting day 2 at @gopherconeu.bsky.social let's Go! #gopherconEU #golang

Now a panel discussion with the @golang.org team members Jonathan Amsterdam and Roland Shoemaker here at @gopherconeu.bsky.social #gopherconEU #golang

Amazing panel with the Go team at @gopherconeu.bsky.social #golang #gopherconEU

Good morning and welcome back to day 2 of #gopherconEU! We’re starting with a panel with the @golang.org team - Jonathan Amsterdam and Roland Shoemaker Moderated by @goinggo.net With the #golang questions you all submitted

TamaGo and TinyGo together at last! Hanging with @andreabarisani.bsky.social here at @gopherconeu.bsky.social #golang #gopherconEU #tamago #tinygo

Closing keynote for the day by Prachi Kedar on orchestrating the Go netpoller #gopherconEU #golang

Back from the coffee break to Pierre Gimalac from Data Dog and how they reduced the side of its agents binaries by 77% #gopherconEU #golang

Now on #gopherconEU Amit Yahav and Elad Gavra from Cyolo walk us through the Leak and Seek #golang mystery they solved

Now at #gopherconEU: Daniel Morsig is here to talk about runtime/secret, the new zeroization package in #golang

I'll be giving a full-day workshop at @gopherconeu.bsky.social 2026 in Berlin! "Advanced Go Internals: Compiler and Runtime Mechanics", June 17th. We crack open Go 1.26.1's source code and modify it directly. With some fun exercises included. Come break Go with me 😄 gophercon.eu

Great talk, and he handled the technical problems like a professional!

Back from lunch to the talk of Alex Rios on the Green Tea garbage collector in #golang! #gopherconEU

Next up is Taichi Maeda who shares how did he introduce #Dragonbox to #golang #gopherconEU

Welcome back to #gopherconEU! The opening keynote is by Jonathan Amsterdam from the @golang.org team, speaking about Collections for the #golang stdlib

If anyone ever wonders why I'm openly hostile to floating point numbers in protocol design: This Is Why. Some utterly fascinating and excellent work about floating point number printing being presented at @gopherconeu.bsky.social . Also, I never want anyone to have to think about this stuff. 🫠😅

Heading to @gopherconeu.bsky.social in Berlin. See you there! #gopherconEU

Getting started here at @gopherconeu.bsky.social! #gopherconEU

Opening keynote from Jonathan Amsterdam "Collections For The Standard Library" here at @gopherconeu.bsky.social #golang #gopherconEU

Lightning Talk CFP Now Open⚡ Share your insights with the community in a fast-paced, high-impact format. Submit your idea here: forms.gle/NtXxWbtUuK5i... ⏰ Deadline: EOD Friday May 29 📬 First invites: Monday June 1 #gopherconEU #golang #LightningTalks

#gopherconEU Speaker Spotlight #Golang 1.26's new Green Tea GC uses a cryptographic instruction for bitmap expansion. @alexrios.me read the runtime code to understand why and will walk through the real implementation: mark bits, span queues and the ownership protocol behind it. www.gophercon.eu

#gopherconEU Speaker Spotlight Anette Haferkorn shares hard lessons from building production systems at scale: how to instrument #Golang apps with user journeys at the center, connect technical signals to business outcomes and define SLOs that Product and Engineering can co-own.

#gopherconEU Speaker Spotlight Taichi Maeda ported Dragonbox to #Golang—faster, smaller float formatting—and proposed it for Go v1.26. It caught Russ Cox’s eye and now an even faster algorithm is coming in v1.27. Tickets @ gophercon.eu

#gopherconEU Speaker Spotlight We are excited to welcome back Jonathan Amsterdam from the @golang.org team, who will be delivering our opening keynote with his talk "Collections for the Standard Library" exploring the future of Go data structures. Tickets @ gophercon.eu

#gopherconEU Workshop Spotlight: Advanced #Golang Internals by @jespino.bsky.social Navigate the Go codebase from lexer and parser to the runtime scheduler. Run safe experiments on the compiler and runtime to build a concrete mental model of how Go executes gophercon.eu

#gopherconEU Workshop Spotlight: Demystifying #Golang Concurrency by @ronnas.bsky.social and Jonathan Amsterdam (@golang.org team) Goroutines, mutexes, channels, atomics, race detector, profiler, common concurrency patterns, and hands-on exercises for all levels Find out more: gophercon.eu
