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.

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!

"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!!!

#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.

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...

Looks like #WasmEdge is the first standalone #Wasm VM that supports and enables #WebAssembly 3.0 out of the box.
Big milestone. Shout-out to the team! 🙌
