Say Goodbye to Expensive Geocoding APIs: A Lightweight JavaScript Library for State/Province Lookup

2025-06-04

A startup spent thousands annually on the Google Maps API for reverse geocoding, just to determine users' states. Finding this wasteful, the author built `coord2state`, a lightweight JavaScript library that directly identifies US states from latitude/longitude coordinates. Leveraging US Census Bureau border data and the Douglas-Peucker algorithm for simplification, it achieves 99.9% accuracy at a 0.01° tolerance, weighing in at only 260KB. The library is open-sourced on GitHub and NPM, offering a cost-effective alternative for developers.

Fast vs. Slow System Calls: How Signals Wake Up Blocked System Calls

2025-06-03

This article delves into the core differences between fast and slow system calls in operating systems. Fast system calls (like `getpid()`) return immediately, while slow system calls (like `read()`) may block waiting for external events. The article focuses on how signals interrupt blocked slow system calls, demonstrating with code examples how to handle `EINTR` errors and use the `SA_RESTART` flag. It also explores the nuances of disk I/O and how the kernel handles different system call types, comparing the strengths and weaknesses of various I/O models (blocking I/O, non-blocking I/O, I/O multiplexing, signal-driven I/O, asynchronous I/O, and I/O Uring).

Go Error Handling Best Practices: Avoiding Sentinel and Error Types

2025-06-03

This post explores three strategies for error handling in Go: sentinel errors, error types, and opaque errors. The author argues that sentinel errors and error types lead to code coupling and are not recommended. The best practice is opaque error handling, checking error behavior via interface assertions only when necessary. Use the `github.com/pkg/errors` package to elegantly handle and log errors, avoiding duplicate handling and information loss.

Claude Code: My AI-Powered Terminal Assistant Saves Me an Hour a Day

2025-06-03

For two months, I've run Claude Code in "dangerously-skip-permissions" mode on macOS, bypassing all permission prompts. While risky (I use robust backups), it's saved me about an hour daily. Claude Code isn't just a smarter command line; it's a universal computer interface. I use it for everything from migrating Macs and converting blog posts to generating test data, managing Git, and automating system tasks. Its command-line-first design and ability to understand context make it highly efficient, though response time can be a limitation. Unlike Warp, Claude's "dangerous mode" allows for continuous workflow without constant permission requests. This represents a paradigm shift in developer tools – from command execution to intent understanding and action. It's not about AI replacing developers, but about developers becoming orchestrators of powerful systems.

Why GUIs Need at Least 2.5 Iterations: A Critique of Lean Software Development

2025-06-03

This article critiques the limitations of Lean Software Development, arguing that its analogy of software development to a factory assembly line is fundamentally flawed. Software development is more akin to a design process, requiring iterative experimentation to discover what users truly want. Using GUI development as an example, the author highlights how building GUIs often involves multiple iterations before achieving a satisfactory result, vastly different from the linear flow of a factory production line. The concept of 'waste' in Lean Software Development proves difficult to apply to software, neglecting the importance of exploration and discovery. The author contends that successful software development resembles a process of discovery, not manufacturing, demanding a deep understanding of user needs and continuous improvement through iteration.
