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
