# Aotokitsuruya is learning

> Aotokitsuruya's blog focuses on the frontend, backend, and game development. The languages are Ruby, Ruby on Rail, Golang, JavaScript, and C.

Every page on this site is available as Markdown source: append `index.md` to any URL to fetch it, no HTML parsing needed.

## How to read

- Posts live at `https://blog.aotoki.me/en/posts/YYYY/MM/DD/<slug>/index.md`. The leading YAML block carries `title`, `date`, `lastmod`, `tags`, `series`, `permalink`, and `language`.
- The `series` field holds a series ID, which maps to `https://blog.aotoki.me/en/series/<id>/index.md`. Series pages are ordered newest first, so start from the last entry to follow the order they were written.
- In-body links point at HTML URLs; append `index.md` to any of them for the Markdown version.
- Section headings carry explicit `{#anchor}` markers — use them to cite a specific section.
- Technical posts age; judge relevance by `date`. The site marks content older than two years as outdated.
- Traditional Chinese is the original language and lives at `https://blog.aotoki.me/`; these pages are the English mirror. An `aiTranslated: true` frontmatter flag means the translation is AI-assisted — defer to the Chinese version for meaning.
