 Hi, so this is a product we built called here now. It's somewhat similar to yellow, but not exactly so So the problem we were trying to solve was basically that all the networks are Twitter Facebook, whatever They are awesome at keeping you in touch with people who you already know But what about people like for example in this room? Whom I don't know but who are all Android developers and people I would like to get in touch with So there's no way that while I'm giving a talk you can send me a feedback or something I mean you can use talk funnel, but what about a normal non-geeky conference or anything? So here now is about the people who are here and now and if you were in the talk call In my talk on pass. We are using pass as the back-end So you will see some capabilities of pass here. Basically. We are using it for playing around with our data for all sorts of purposes, so You can so let me just show you so I'm signing in here Okay, the password is password. So if you're looking or I forgot my password. I'll use the Facebook thing that will be your login, so sorry Just a sec, so the login is also built using pass by the way. Yep So yeah, so first thing is you get is So this is what you'll get is a location based feed the first is just some tips we have built in But there here you are seeing like this is 37 kilometers away or something like that So if I go ahead and create a post here So So it shows up here now the feed is based on three different parameters basically So it's a factor of location time and relevance Relevance is depending on how many other people have interacted with it interaction may be in the form of replies We have a plus one button and stuff like that. So that is how we are controlling spam sort of and Yeah, so basically this is something like Assume a place place book if you will Whatever fee whatever is happening at a place you can find that out so this is in past we had basically one large table called posts and this is Running a past cloud function, which is which takes in all these parameters regarding a post and Generates a feed for every person on the fly and if you want to see So the same table you can filter it on different characteristics, so I can just go and go to my profile So here, I'll just see what all I have posted So again Because we were using the backend We did not have to build this. This was out of the box Similarly, we have something called spaces which is which is not location based I mean the list of spaces spaces are like groups The list of spaces is location based, but inside that it's like a chat kind of environment. So you can So it's a chronological sorting of messages Which are again in just one big humongous table post and this provides a Chronological sorting of that data so, yeah, this is just that and And and yeah, so image support is there as you would expect and Then you can go and So you can just go and comment also Okay. Thank you. I think that's it. Thank you Warren
