In this podcast, the hosts discuss the seven deadly sins of Go and the importance of considering different use cases in software development. They also explore the evolution of concurrency patterns in Go, the concept of gluttony in programming, and the pros and cons of Go frameworks. Additionally, they emphasize the importance of avoiding unknown unknowns and over-engineering, and share their opinions on vampires. The significance of documentation and sources of information in investigating code changes is also highlighted, along with the unpopular opinion that Go is a great language for software engineering.

Quick takeaways
Proper error handling is crucial in Go to ensure code quality and avoid crashes or unexpected behaviors.
Mindful evaluation of dependencies and frameworks is important to prevent code overload, complexity, and potential security vulnerabilities.
Avoid overconsumption of resources, including lines of code, by focusing on simplicity and efficiency for improved maintainability and performance in Go.
Deep dives
Wrath: Misusing panic and not handling errors properly
Wrath involves misusing panic by using it in situations where errors should be properly handled. It's important to treat panic as an exceptional case rather than a routine flow of your code. Instead of relying on panic or must functions, make use of error handling and return proper errors when necessary. By properly handling errors, you can ensure better code quality and avoid unnecessary crashes or unexpected behaviors.
Greed: Overindulgence in dependencies and frameworks
Greed in the context of Go refers to overindulgence in pulling in excessive dependencies and frameworks. While using dependencies and frameworks is not inherently wrong, it becomes a sin when they are reflexively reached for without considering the actual need. Overloading your code with unnecessary dependencies can lead to increased complexity, maintenance difficulties, and potential security vulnerabilities. Instead, adopt a more mindful approach in evaluating if the dependencies and frameworks are truly necessary for your specific use case.
Gluttony: Overconsumption of resources and lines of code
Gluttony in the Go context refers to overconsumption of resources, including lines of code. This can manifest as excessive code and dependencies that are not needed for a given task. Gluttony can lead to bloated codebases, decreased performance, and increased maintenance efforts. It is important to focus on simplicity and avoid pulling in unnecessary resources. By keeping your code lean and efficient, you can improve code maintainability and overall performance.
Lust: Misusing powerful features like goroutines and channels
Lust in the Go context refers to the misue of powerful features like goroutines and channels without proper consideration. While goroutines and channels are foundational elements in Go's concurrency model, they should be used judiciously and only when necessary. It is common for newcomers to Go to overuse these features, leading to unnecessarily complex and convoluted code. Instead, it is important to carefully evaluate which concurrency features are required for the task at hand and implement them thoughtfully to avoid unnecessary complexity.
Avoid Preemptive Over Engineering
Preemptive over engineering should be avoided in software development. While future-proofing to an extent is reasonable, it is important not to get carried away with anticipating every possible future scenario. Building excessive complexity into the codebase based on unknown and uncertain requirements can lead to unnecessary complications, bugs, and wasted effort. Instead, it is recommended to focus on designing and implementing solutions for the known requirements and adapt and scale the codebase as new requirements arise.
The Significance of Well-Designed Software
Designing software properly is one of the key aspects of software engineering. When software is well-designed, it becomes easier to write high-quality code and maintainable systems. The podcast episode highlights that Go is an excellent language for writing software when the focus is on proper software design. However, it also emphasizes that simply relying on language features like memory safety and type safety cannot compensate for poor software design. Therefore, the episode encourages developers to prioritize software design and leverage Go's strengths to create reliable and efficient systems.
John Gregory’s GopherCon talk “7 Deadly Gopher Sins” is the ostensible basis of this spooky Go Time episode, but with Mat Ryer at the helm… the only thing to expect is the unexpected. And failed jokes. Expect lots of failed jokes.
