• Flyway

  Flyway by Redgate • Database Migrations Made Easy.

  

Project mention: Let's write a simple microservice in Clojure | dev.to | 2024-04-26

The session logs show that the application loads configurations and establishes a connection with a PostgreSQL database. This involves initializing a HikariCP connection pool and Flyway for database migrations. The logs confirm that the database schema validation and migration checks were successful. The startup of the Jetty HTTP server follows, and the server becomes operational and ready to accept requests on the specified port.

• Byte Buddy

  5 6,012 9.0 Java

  Runtime code generation for the Java virtual machine.

Project mention: Monkey-patching in Java | dev.to | 2023-09-21

As seen above, the API exposes the user to low-level bytecode manipulation via byte arrays. It would be unwieldy to do it directly. Hence, real-life projects rely on bytecode manipulation libraries. ASM has been the traditional library for this, but it seems that Byte Buddy has superseded it. Note that Byte Buddy uses ASM but provides a higher-level abstraction.

  Color libraries for Material You

  

Project mention: Built a multiplatform RSS app built using Kotlin and Compose Multiplatform | /r/androiddev | 2023-05-23

It was fun learning more about KMM and also trying out Compose for iOS. You can download the app from GitHub Releases (for now Android 12+ because of the unbounded blur any suggestions on how I can get this in a backwards-compatible manner?). Here are a few screenshots showcasing the app. I have used Material You based theming to dynamically theme the app based on the content image, it works on both Android and iOS. For that I had to extract the Material Color Utilities library into a KMM package I can use, you can find it here if you are interested and want to use it.
