I promise to have one session of topic streams per week, and I want to put that in my schedule. Do you think Friday from 12-14 GMT is the best time for it? Let’s discuss the timing below. Let me know if any other time works better for you. I’ll gather your suggestions and put it to a vote to find the time that suits most of us the best.

Now that we’ve had two sessions on DP, we can either move on to another topic now, or have a third session on DP before jumping to the next topics. What do you prefer?

The topic of the third topic stream?
It was a close competition between DP and Graph.

I’ll cover DP #3 tomorrow, and then we’ll take a break from DP to give everyone some time to practice what we've discussed.

Next week, we’ll have our topic stream on Graph.

Thank you all for your votes, comments, and suggestions!

Sorry for postponing today’s livestream. I know some of you may have planned for it, and I apologize for the inconvenience.
I’ll be hosting the topic stream tomorrow (Saturday) at the same time (12 - 14 GMT). I hope that still works for you. Please let me know in the comments below if this time does not work for you.
