WASM I/O • 19-20 Mar • Barcelona 2026 Easy, fast, and safe: pick all three with Swift for WebAssembly • Wasm I/O 2026. A 2-day WebAssembly conference in Barcelona, Spain

Two years ago at #WasmIO I talked about (at that time) experimental support for #Wasm in #SwiftLang. Today I'm back on stage with Yuta Saito to present what's new in now official Swift for Wasm! If you're attending, I'm happy to chat in the hallway track 🙂

if you're coming to @wasm.io in Barcelona, or are in or around Spain and could come but can't buy a ticket: I've got two tickets!! This is the best #webassembly conf there is.

The first two people from whom I receive a communication here or at hachyderm.io/@squillace will get one of those tickets.

Thank you to our Silver Sponsor Pantopic for helping make Wasm I/O 2026 possible! #wasmio26

If you're coming to @wasm.io this week and want to build and run #webassembly components in #hyperlight-wasm this Thursday, you'll need a linux box (or windows with wsl) that has nested virt enabled.

M3 and M5 macs **may** work, but that's coming in really hot. So get those cloud VMs ready to use!

can't believe @wasm.io is less than a week away! @andreatp.bsky.social and I will be there for our session "The State of Zero-Dependency Wasm" with the latest from #wazero and #chicory 🚀

"breaking news" -- hilarious. :-P But this is reasonably great #webassembly news right here, I must admit.

Now that I look, I see this at @wasm.io next week in #barcelona: 2026.wasm.io/sessions/bui...

Gonna be asking questions!!!

A big thanks to our Wasm I/O 2026 Platinum sponsor,
Akamai!

Thank you for supporting the WebAssembly ecosystem! #wasmio26

WASM I/O • 19-20 Mar • Barcelona 2026 Hands-On with Hyperlight and Wasm [Workshop] • Wasm I/O 2025. A 2-day WebAssembly conference in Barcelona, Spain

#webassembly is one of the great technologies will make distributed computing better -- and already does. The @cncf.io project #hyperlight helps all that. Come to @wasm.io for 2026.wasm.io/sessions/han... and learn how you can wrap hardware protection around wasm components -- and almost anything.

The coolest thing, IMHO, is coming to #BCN: @wasm.io, March 19-20. Two days of everything to do with #webassembly, tons of languages, updates, and customer stories. @microsoft.com is proud to be a Gold Sponsor, along with other sponsors @igalia.com and @thenewstack.io !!!

Looking for a distraction prior to registering for @wasm.io? Or planning a trip to @cncf.io #kubeconeu? I blather on about #webassembly and why it's interesting to Microsoft (and, why it might be interesting to you) with the #F5 crew @ospencer.dev and Joel Moses www.youtube.com/watch?app=de...

We are excited to welcome @microsft.bsky.social Azure as a Gold Sponsor for Wasm I/O 2026!

Thank you for your continued support! #wasmio26

Looks like #WasmEdge is the first standalone #Wasm VM that supports and enables #WebAssembly 3.0 out of the box.
