In this article we will be learning on how to work with VCR, how to configure it and how to write tests for third-party services.
Few things are more frustrating than slow, flaky test suites. You're ready to deploy, wait 20 minutes for CI to run, only to find that a test failure in code you've never touched is blocking you. You dig into the source and find the problem: an external API call. It works (slowly) most of the tim...
Learnings and tips and tricks on how to set up and tune odometry for my NASA-JPL Mars Rover, which can be applied on any Autonomous Mobile Robot (AMR).
Excellent tips and ideas
One of several tips on how to tune PID controllers. PID Controllers are algorithms used in all sorts of control circuits. In my case for the control of a robot motor.

What do you do when indexes aren’t enough?
When you first start out the only thing that matters is finding a cohort of customers who truly value what you offer. Growth alone means next to nothing.
p.s. This is a series of articles and each article builds off another. I suggest starting at Part 1....
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?

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.
