I recently been exploring using these cmake-args to optimize my code. For the past few weeks I have just been running "catkin build <pkg_name>". Today when I ran "catkin build <pkg_name> --cmake-args -DCMAKE_BUILD_TYPE=Release" my code ran 10 times faster.

Should I always be running the second command instead with the build type explicitly mentioned as opposed to simply "catkin build <pkg_name>"? Is this a safe practice? I could not find much about this on the internet and I would greatly appreciate some advice.

When you launch the freenect node there are topics with camera/depth/(SOMETHING) and camera/depth_registered/(SOMETHING). What is the difference between these two things?

Hi guys I would like to set up ROS2 on my laptop so that I can contribute to the community. However, I have ROS1 installed on my computer. Will this be an issue? If so, what is a good way to prevent any conflicts between the two systems?

Hey tfoote thanks for your help :)

In ROS1 if I wanted to publish an Odometry msg I would use rospy.Time.now() to get the current time and publish the odom msg using that time. However, I haven't been able to find anything similar in ROS2? Does anyone know what functionality I can use to get the time for a msg I am publishing in ROS2?

now = rospy.Time.now()
odom = Odometry()
odom.header.frame_id = self._odom_frame
odom.header.stamp = now

Replacement for rospy.time.now() in ROS2? In ROS1 if I wanted to publish an Odometry msg I would use rospy.Time.now() to
