Hi! I'm Ankush!

I’m a 👨🏻‍💻 programmer who loves technology. From 🕸 web-development, deep-learning, devops to everything that Elon Musk does.

In addition to coding, I also look at how good products & businesses work from many contradictory points of view.

Recently, I have started thinking a lot about testing as a way to improve code quality so you’ll find a lot of related posts.

This blog is the way I process my 🎲 thoughts and solve problems. If you read any, try scrutinizing them and see if they hold.

I treat this blog as a wiki, so old post of frequently reworded or deleted.

  • Incremental Improvements
    • Tip: Leave TODO as comments for your future self. These could include how you want to improve the code but don’t have time right now to do it. Hopefully your future self will handle it.
  • Upgrading Fast (get rid of Legacy)
    • Do it one step at a time.
      • Making a big bang change is never feasible.
        • Simple upgrades such as — Custom SQL executors in code to using an ORM.
        • Or they can be a little bigger such as — Going from AngularJs to Angular.
        • Or a much bigger one like — Going from Java to Kotlin.

  • Remove functions and variables which you do not use.
  • Variable argument lengths
    • Python: *args, **kwargs (more than just variable-length argument)
  • Default Arguments
  • Use annotations/decorators
    • Python: Decorators
    • Spring Boot (Java)
      • Java: For JPA
      • Java: Map using Mapper. Don’t create your own logic.
      • Java: Project Lombok to avoid boilerplate
  • Remove duplicates
    • Use existing/inbuilt methods rather than new once

  • Keep your implementation as simple as possible
  • Knowing the basics of time and space complexity goes a long way.
  • Additional Tip: Always use parent interface for the type
  • When trying to find duplicates
    • Use Set instead of Lists
  • Java: If you know the size of the list
  • Always have your algorithmic logic in a separate function
  • Rather than implementing own logic, take 5 minutes to see if your modules already provide the implementation
    • Example: Sorting in Javascript/Typescript
