Hi, everyone!

I've been accepted to work with GnuRadio for this year's Google Summer of Code.



The task I intend to implement is porting SIMD code to gr-web through wasm,

which enables gnuradio more extensible and popular through the browser.



I am really sorry, this post seems a bit late due to some unexpected problems 
with the building gr-web from the source.



Last week's blog:

 https://eat4toast.github.io/2022/07/04/week1.html



I will post a weekly update on the mailing list, well the blog will record more 
latest progress.



Yours,

Yao.

Hi Zafar  - are you trying to run python code which was built on another 
machine?


Or are you running gnuradio remotely?

Which SDR are you using?
