Two talks based on the results of ROSIN will be given at ROSCon 2019 in Macau on November 1st (day 2). At 10:10 listen to "ROS bugs later: Where do we go from here?" --- a reflection based on the analysis of past bugs in the ROS platform. What kinds of bugs do programmers encounter when developing ROS applications? Are those bugs unique to ROS? What can we do to avoid them? At 16:20, Andrzej Wasowski (ITU) will present RxROS: a thin reactive programming layer for ROS that allows to program nodes without callbacks and locks. This eliminates bugs like deadlocks and races by design
