Brilliant Ideas, Bad Pitch? How to Communicate Tech Proposals That Win Support
We all know the drill: refactoring makes our code easier to understand, static analysis points out complex areas and code smells, tests help us track and improve our code's coverage, and Domain-Driven Design lets us build code that directly reflects the business rules. Sounds logical, right? Yet, we often find it tough to convince managers, product owners, and other stakeholders of the value in these practices. What's...

Hey all, While working with Go, I kept running into situations where I needed to map data between structs β especially DTOs and domain models. After using AutoMapper for years in .NET, the lack of a similar tool in Go felt like a missing piece. So I built go-mapper, a lightweight struct mapping library that uses generics and reflection to reduce boilerplate. It supports: Automatic mapping between structs with matching...
