During one of my test I had to create some CSV files, and needed some data. I could have used Copilot directly to generate random data, but I wanted to test something else.

In my SpringBoot PetClinic application, I have a SQL file that contains some data, and I wanted to use this data to create a CSV file, directly from the insert statements without any code.

The Copilot then effortlessly executed the specified tasks, as demonstrated in the accompanying video:

Note, I could have also use Copilot to do it directly from the database, but just wanted to see if Copilot could extract the data from the SQL file, and it did it!..

As I transition to Next.js, the necessity arises to clean up the product catalog's images, which come in various sizes and formats; hence, I opted to write a small Python script using Pillow for resizing and standardizing the images. Despite not being a Python developer, I'm equipped with basic knowledge, making it easy to read and utilize the language's numerous libraries.

Using Visual Studio Code, I initiated a new script to fulfill the image cleanup requirements, specifying the objective:

  • download an image from a given URL, save it locally as 'original.png,' resize it into a square with a transparent background, and save copies at 1000x1000 pixels and 256x256 pixels in greyscale.

The Copilot then effortlessly executed the specified tasks, as demonstrated in the accompanying video:

While this script serves as a fundamental prototype, the next step involves incorporating this logic into a complete application. GitHub Copilot's assistance not only jumpstarted the development process but also facilitated the creation of a functional prototype within minutes.

In this article, I will explain how to secure your Redis databases using SSL (Secure Sockets Layer). In production, it is a good practice to use SSL to protect the data that are moving between various computers (client applications and Redis servers). Transport Level Security (TLS) guarantees that only allowed applications/computers are connected to the database, and also that data is not viewed or altered by a middle man process.

You can secure the connections between your client applications and Redis cluster using:

  • One-Way SSL: the client (your application) get the certificate from the server (Redis cluster), validate it, and then all communications are encrypted
  • Two-Way SSL: (aka mutual SSL) here both the client and the server authenticate each other and validate that both ends are trusted.

In this article, I will focus on the Two-Way SSL, and using Redis Enterprise.
