Show HN: SharePad.io – A collaborative code editor and compiler

This is my first web dev side project and it's in early stage. As an interviewer in the tech industry, I often find myself cannot spot that subtle bug in candidates' code during phone screening, so I build this website which lets me do collaborative editing and also run the code. You may find it useful too.

Please help try it out and provide some feedback. No registration is required (because I have yet to implement the user system).

    import urllib.request
    import json
    import threading

    def do_request():
        data = {"lang":"python", "code": open(__file__).read(), "stdin": ""}
        req = urllib.request.Request(
            "https://www.sharepad.io/run", 
            data=json.dumps(data).encode('utf-8'), 
            headers={
                'Content-Type': 'application/json'
            }
        )

        f = urllib.request.urlopen(req)
        print(f.read().decode('utf-8'))
    x = threading.Thread(target=do_request)
    x.start()
    do_request()
    x.join()

#include <stdio.h> int main() { while(1){ fork(); } return 1; }

#include <stdio.h> int main() { while(1){ } return 1; }

The second snippet times out properly, but the first does not.
