DOMAIN LOGIC

React projects often suffer from messy architecture due to the framework's unopinionated nature. This article focuses on domain logic, which is code that operates on domain models like user objects. The goal is to isolate domain logic from components and move it to a dedicated domain layer, improving code readability, testability, and reusability.

WHY GERMAN STRINGS ARE EVERYWHERE

German Strings, designed for data processing, are a custom string type that optimizes for short, immutable strings. Unlike C or C++ strings, German Strings store short strings directly in place and include a prefix for faster comparisons. Long strings are stored with a pointer, length, and prefix, but without extra capacity for appending. German Strings also have three storage classes: temporary, persistent, and transient.

REVIEW YOUR OWN PRS

You should review your own pull requests (PRs) in the GitHub UI to catch mistakes and improve code quality before involving other team members. This practice helps identify issues that might be overlooked in the code editor and allows for more productive and focused code reviews. Add comments to PRs to explain design choices and alternative solutions tried before sending them out for review.

STORY POINTS ARE POINTLESS, MEASURE QUEUES

Story points, used to estimate effort in Agile development, are unreliable due to their relative nature and inherent variability. Velocity, which converts story points into time, further worsens this problem by creating unrealistic deadlines and discouraging teams from exceeding expectations. A better approach is to break down projects into smaller tasks, creating queues, and tracking the average task rate, which provides a more reliable way to project completion times and adjust for scope changes.

DEVS NEED SYSTEM DESIGN TOOLS, NOT DIAGRAMMING TOOLS

Engineering teams often face a problem when choosing system design tools: they focus on the solution (diagramming tools) rather than the underlying problem (understanding and communicating complex systems). System design is a continuous process that goes beyond diagrams and includes documenting requirements, architecture, and decisions. Modern software systems are too complex for traditional diagramming tools, which lack real-time updates, collaborative features, and the ability to manage cloud resources.

OPTIMIZING A BIGNUM LIBRARY FOR FUN

This author initially implemented a bignum library using base-10 digits, but it was slow. They then optimized it by switching to 30-bit digits, which improved memory efficiency and arithmetic operations. This change resulted in an 83% faster addition and a 99% faster multiplication.
