Testing network services in Ruby is easier than you think

Testing network services in Ruby is easier than you think You’ve started a new project and it’s time for your code to depend on a third-party service. It could be something like ElasticSearch, Resque, a billing provider, or just an arbitrary HTTP API. You’re a good developer, so you want this code to be well tested. But how do you test code that fires off requests to a service that’s totally out of your control? March 4, 2022 at 02:53PM

Merging data from multiple LIDAR(s) in ROS

Merging data from multiple LIDAR(s) in ROS Light radars or LIDARs are used in robotics, drone engineering, IoT etc. for a wide range of applications. A typical lidar uses ultraviolet, visible, or near infrared light to image objects. It can target a wide range of materials, including non-metallic objects, rocks, rain, chemical compounds, aerosols, clouds and even single molecules. They are used extensively in building autonomous systems such navigation, detection, task actuation etc. LIDAR February 3, 2022 at 10:14PM
