Debugbar For Ruby on Rails
Link: Debugbar For Ruby on Rails: "Rails debugging dev tools for faster development. Inspect your request details (queries, logs, cache, jobs and more)."
This is super useful for rails apps. Will it work for other frameworks like Sinatra? I haven’t tried this yet but it looks promising.
ROS opencv camera driver that uses cv::VideoCapture
Link: ROS opencv camera driver that uses cv::VideoCapture: "ROS opencv camera driver that uses cv::VideoCapture - OTL/cv_camera"
Ok this is also for me to remember important links! Here is the source code for the opencv ROS support for the camera. I now prefer it over Raspicam.
Raspi cam documentation

An Introduction to LiteStack for Ruby on Rails | AppSignal Blog
Link: An Introduction to LiteStack for Ruby on Rails | AppSignal Blog: "In the first part of this series, we'll set up an example Rails application and introduce the basics of LiteStack."
A multi part series on the so called LiteStack. People seem to be coming back around to using SQLite for their production databases.

I am looking for a substitute for fideucials with ROS. I have used raspicam_node from Ubiquity Robotics and it does work but it took a lot of playing. I wonder if opencv would work better.
