Vote count: 0 We have a preexisting SQL database that holds our data and will be updated from time to time. I've just stumbled across Realm and don't quite understand how it works at the moment. From the examples I've seen it looks as if Realm creates the database locally on the mobile device (please correct me if I'm wrong). This is not what we want. We want our data to live on some server and then pull that into the application. Can this be done purely with Realm? Or should we somehow pull from the SQL server? What's the best way to achieve this? Thanks! asked 1 min agoD-W Let's block ads! بخوانید...

Vote count: 0 I have multiple points forming many circles in a 2d plane and need to identify and sort them for further calculation. I have the [x, y] co-ordinates of each point and a number representing each point. All point numbers in one circle should be sorted in a list. and then point numbers of next circle should follow. Say each circle is formed by 6 points. They should be first and then next 6 points of the adjacent circle should follow. I identified that Convex Hull is a way of identifying closed polygons. This is similar but I want it to identify multiple convex hulls in the same plane. I think this should be possible in python. Can anyone help on this please? asked 7 secs agouser66...

Vote count: 0 I've got an application with a Raspberry Pi ruing Debian that is pretty performance demanding and I am trying to avoid starting X when booting and jumping directly into the program. This works fine, but if I would like to use the 'imshow' function in OpenCV, it does not work correctly, instead it says 'GTK-Waing: caot open display" and exits the program. Is it feasible to display a fullscreen image/video capture with opencv using imshow or any other function without X, or is it entirely dependent on the X?

Vote count: 0 It doesn't look like I have wired my web crawler (built using Python's Scrapy) properly with my Node application.
