In Go programming, a common practice is to defer the `Close()` method for values that implement the `io.Closer` interface after checking for errors. This is frequently seen when handling HTTP requests or files. However, this idiom can lead to issues, particularly with writable files, as deferring a function call ignores its potential return value, which may include errors. Errors from the `Close()` method can occur even if previous `Write()` calls succeed, due to the nature of computer architecture

The article discusses the challenges faced by early-stage startups when adopting microservices architecture too soon. While microservices are praised for their scalability and flexibility, they are more suitable for large companies like Google and Netflix. Startups, often operating with limited resources and small teams, may encounter unnecessary complexity by breaking their products into too many microservices, resulting in what the author terms "nano-services." This approach can lead to problems such as operational overhead and difficulties in managing a fragmented architecture, ultimately hindering the startup
