File Organization: Type vs. Context

This article explores two common approaches to organizing code files: by type and by context. Using a real-world Identity and Access Management (IAM) system as an example, the author compares the pros and cons of each method. While organizing by type is convenient for finding specific file types, it falls short in understanding the business logic and maintainability of the code. Organizing by context, however, more clearly reveals the system's business processes, facilitating team collaboration and troubleshooting, and is better suited for large projects. Ultimately, the author concludes that the best choice depends on team size, project characteristics, and workflow, with no absolute superior method.

The Play of Pull Requests: Crafting Reviewable Code Changes

2025-09-25

Saša Jurić's talk at Goatmire Elixir Conf transformed code review into a compelling narrative. He highlighted the common problem of unwieldy pull requests (PRs), leading to superficial reviews, security risks, and unmaintainable codebases. The key takeaway: reviewable PRs should ideally take 5-10 minutes to review, ideally under 300 lines of code. This is achieved by crafting concise, story-telling commit messages that clearly explain the rationale and steps of each change. Breaking down large features into smaller PRs and utilizing tools like `git fixup` to maintain a clean commit history are crucial for efficient code review and higher quality code. The talk emphasized that saying "I don't understand" is better than a meaningless "LGTM."

Earth's Water: Homegrown, Not Alien?

A new study published in Icarus challenges the long-held belief that Earth's water originated from space. Researchers analyzed an enstatite chondrite meteorite, whose composition resembles early Earth. Using a synchrotron, they discovered hydrogen within the meteorite, proving it wasn't terrestrial contamination. This suggests the building blocks of Earth were far richer in hydrogen than previously thought, providing enough to account for Earth's water. The study strongly supports the theory that Earth's water is native, a natural consequence of the planet's formation, rather than a result of asteroid impacts.
