Using interfaces in Go the right way

Interface programming constructs describe the behavior of objects without specifying underlying implementation details. Interfaces in Go are powerful and can be satisfied implicitly, meaning that types can implement an interface simply by declaring the methods defined in the interface. This article presents the correct way to use interfaces in order to write maintainable Go Code and follow the SOLID principles, such as interface segregation, which promotes the definition of interfaces that have a clear and focused purpose, reducing unnecessary dependencies and improving testability.

Scrubbing sensitive data at 180MiB/sec/core

Redacting sensitive data from traces with static analysis and JSON tokenization.

Replace a Dockerfile with Go (or Python, or Node.js)

Dagger SDK enables easy creation of pipelines and container configuration, replacing the need for a dockerfile. Develop and configure container dependencies with go, python or nodejs SDK, and download and build app source code in your Docker container.

Focus on the Happy Path With Step Functions

This article discusses a coding pattern in Go called step functions, which allows for a more declarative approach to defining the “what” of a program’s logic, separating it from the “how”. The author of the article provides examples and code snippets to demonstrate the implementation of step functions in Go.

✅ Raspberry Pi Coding in Go: Traffic Lights

This article provides a guide on how to create a standalone traffic light using the Go programming language on a Raspberry Pi. It includes instructions on setting up the Raspberry Pi, installing the necessary software, and compiling and running the code for the traffic light.
