Real Time Weekly: June 20th 2016

We have some interesting articles this week on Websockets and WebRTC, including WebRTC thoughts from the Slack engineering blog.  Last week we also held our WebRTC event in Argentina, and it was a great group!  We are working on the video from the event, and you can expect us to share that in future issues.

As always, if you have tips, event announcements, or suggestions, please contact me directly at
