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!
