问题 I want to present an alert when my app launches for the first time that day. I think the place to do this is the appDelegate (correct me if i am wrong). I have two problems, one: i don't know which of the functions in the appDelegate the function should reside under (have currently chosen just func application), and second: i don't know how to present the alertController to the view that is open. Thus far i have done this func application(application: UIApplication,

问题 I would like to execute code every time the application begins (not only the very first time the application begins so getSharedPreferences doesn't help ). I've tried to write the code in onStart() of the main Activity, but that code was executed everytime I entered the activity including times I back to this activity from other activities (so onStart() doesn't help ).

问题 I was educating myself about website launches. I was reading this document to prepare an implementation check-list for my future website launches. On page 11, they mentioned Schedule backups for development, testing, and production environments I can imagine taking backup of a database and website code. How can someone automate and schedule backup of an entire x, y or z environment ? If this is a very broad question then I do not need the step by step document for doing this. Maybe some

问题 I want to launch multiple turtlebots using Gazebo, and move each one from them separately with cmd_vel_mux topic. Namely, I would like to send message to topic {robot_name)/cmd_vel_mux .

Therefore, gazebo is launched but the robots doesn't move. I tried to launch mobile_base_nodelet_manager from ros nodelet package for
