23. Business Model
TLKR.io is free as long as you help
others practice your
native language.
For every minute you help
someone, you’ll get two
to practice.
If you only have time to practice,
you can buy more minutes.
28. Technology
WebRTC enables modern browsers to:
○ P2P data sharing
○ Access webcam and microphone
(without external plugins)
○ P2P audio / video calls
○ And other stuff I don’t have time to explain today…
WebRTC is supported in:
○ Google Chrome (including Android)
○ Firefox (including Android)
○ Opera
○ Bowser (only iOS)
29. IF IT IS P2P
WE DON’T NEED
A SERVER,
RIGHT?
MEH!
Technology
30. Technology
WebRTC P2P video calls require:
○ STUN server
google public stun server
To figure out what’s the public IP for each peer.
○ Signaling server
To “introduce” one peer to another.
○ TURN server (optional)
node.js + socket.io
we don’t have one (yet)
As fallback for peers who are behind complex
firewalls.
31. We are at the starting point
of our adventure.
We still need to figure out
how to get traction.
You can help us to make
TLKR.io awesome.
