Serving Hugo on Azure with Continuous Integration

Why? In my last post, I walked through how to configure your Azure blob and CDN to serve your static website. The deployment script outlined in that post is fine for a simple blog site. However, it is not a solution if you have a site that is contributed by multiple people.

Custom NodeJs Deployment on Azure Web App

One of the advantages of using Azure Web App is how easy it is to deploy a NodeJS app. If you have an app as simple as this one, Azure Web App will pick it up, install all the node dependencies, and serve the app on port 80. And you are done!!! Unfortunately, a lot of times, you might want to venture outside the comfort of auto-deploy land, and do some customization....

Power of Transformers (not these robots 鈫)

About a year ago, I was tasked to write an API for a mobile application for the Dean of Students office. While the main functionalities were finalized, the app鈥檚 development was still in its infancy. This means that the API鈥檚 output and how it would be best-suited for the app鈥檚 consumption was still very much undefined. We had to use transformers to separate the API鈥檚 logic layer from its presentation....

Also validate the credit card again the Luhn algorithm which is the algorithm used by most CC companies....
