2016-08-18 13:20:53 -0500	commented question	Publisher sleeping forever Maybe /use_sim_time is active but no bag is played? This would mean that time does not go forward and hence the sleep would never expire.

2016-08-18 09:53:41 -0500	answered a question	Last node handle goes out of scope but callbacks still work. Why? If you look at https://github.com/ros/ros_comm/blob/... , the Subscriber keeps a copy/reference to the node handle. So as long as it exists, there is yet another referenced handle that will prevent the node to shut down.

2015-10-20 03:18:37 -0500	commented question	raise IOError("could not find %s on the ros package path" % msg_pkg_name). Ros is not capable to find a package in the ros_package_path Did you source your workspace's setup.bash?
2015-10-20 03:13:07 -0500	commented answer	How to set and access local parameters when launching a nodelet? I would assume each nodelet is in a different namespace, and so would be the parameters.
2015-10-14 02:05:21 -0500	answered a question	How to set and access local parameters when launching a nodelet? To pass a parameter value to a nodelet, try either passing it as an argument on the command line when you run the executable that loads the nodelet (i.e. "_param:=value") or set the parameter using ros::param::set("~param", value). In either case the nodelet should be able to access it using getPrivateNodeHandle().getParam("param", value).
