Useful Patterns for Building HTML Tools

Simon Willison shares his approach to creating over 150 single-file HTML applications using LLMs. These tools combine HTML, JavaScript, and CSS without build steps, making them easy to create, host, and maintain. Key patterns include using CDNs for dependencies, persisting state in URLs, leveraging localStorage for secrets, and taking advantage of browser APIs for file handling and clipboard operations.

Mechanical Habits, Release Every Friday

Weekly releases transform software delivery by making each release low-stakes and low-effort. Small releases mean easy changelogs, minimal risk assessment, and no pressure to hit specific deadlines since delaying a feature by one week is trivial. The second-order benefit is even more valuable: weekly cadences force teams to maintain constantly healthy codebases, leveraging temporal locality instead of scrambling before big releases.

Use Python for Scripting!

Shell scripts often fail across different operating systems because GNU and BSD versions of common tools work differently. Python solves this with its standardized library that works identically on all machines, making it ideal for cross-platform scripting. Plus, Python's readable syntax and extensive built-in functionality eliminate the need for cryptic commands and workarounds.
