Value Object, Entities and validation at construction time
As I'm building my personal annotation project, I come across code that the LLMs have decided to spread around and duplicate variables instead of reusing an existing one, so I step aside and look around only to see tech debt, which is asking to be refactored and I'm reminded to start using value objects. Your 2nd rewrite will have a different type of tech debt Value objects The book…

If your dependencies are not cached on the runner, you will be getting a different build…
What I learned applying as a graduate Software Engineer
About more than a year ago(before the down of LLMs) I was with a friend tossing project ideas to work on, I threw the idea of training a model on our notes to help us pass interviews, it boiled down to piping Zoom audio stream into speech to text then into a language model trained on answering software dev questions, and finally have the answers rendered onto a screen. This was of course before…
