Presentation on experiences with ros2
Started using ROS2 toward end of bouncy release, upgraded to crystal shortly after release, now have returned to ros1.
Maybe will try again when Dashing is release (June 2019?), or will wait for certain key features (some of these maybe already have been achieved, or were already achieved when I was using it but the right way wasn't clear to me):
- ros2 topic echo /image_raw shouldn't take 100% cpu, rqt_image_view shouldn't take 50% cpu. This may be fixed with https://github.com/ros2/rosidl_python/pull/ 35
- ros2 node info should handle namespaces
sudo apt install sidplay
- Coco - Markus Muller - https://csdb.dk/sid/?id=18840
- Ace II - Hubbard
- Commando - Hubbard

Visualize the data as a point cloud?
The files look to be mainly csv files.
http://cdn.gea.esac.esa.int/Gaia/gdr2/gaia_source/csv/ has many files.
Updating many repositories to use ros2 bouncy: image_manip, usb_cam, v4l2ucp, imgui_ros
The intent is to develop/learn how to convert ros1 packages first along with the entire workflow of building and debugging and deploying and then take advantage of ros2 features.
No verbose option?
cd into build/package_name then run make VERBOSE=1 right there.
Does running a release build (using a mixin) then forgetting to specify release the next time clobber all the old built files,
