This is a learning wiki. It began as a daily study habit, and it is public because what is learned is worth sharing.
How it is made
- Every day: one lesson, one coding puzzle, new notes for the terms the lesson uses, and one older note made deeper.
- Written with Claude, from primary sources: the RFCs, the HTML and ECMAScript standards, Python’s PEPs, official docs and papers. Each note lists its sources.
- Checked by scripts: every link must lead somewhere, and every code block marked as runnable is run before the site is published.
- Read as it is studied, and corrected when something turns out wrong.
What it may get wrong
Mistakes are possible, especially in fast-moving topics. If you find one, open an issue on GitHub. The sources on each page are the authority, not this wiki.
