This is really hot, wasix is ​the best
@datarade
The demand for security, compute, and performance will be so high and the shortages of all 3 will be so massive that WebAssembly and http://wasmer.io will be massive.
@solomonstre
If WASM+WASI existed in 2008, we wouldn't have needed to created Docker. That's how important it is. Webassembly on the server is the future of computing. A standardized system interface was the missing link. Let's hope WASI is up to the task!

If I were a billionaire, I'd want to fund Wasmer with about 5,000 trillion yen because it's just too awesome
@loretoparisi
Apparently now not only @FFmpeg but even ffprobe can be natively executed in the web browser via WASM @wasmerio I was waiting for this since a while... #JavaScript #ffmpeg

If I don't touch wasmer soon, I'll be left behind...!
