Blur Focus / chrome-extension-blur
- A Chrome extension that applies a blur effect to specified elements on a webpage, which can be temporarily revealed on hover. Useful for hiding personal information during screen sharing or taking screenshots.

These are the LaTeX packages I developed.

overload / myoverload.sty, last modified : 2026/04/08 (README in Japanese)
- This small LaTeX2e package lets one control sequence dispatch on how many arguments were given (0–9), using \newoverload, \renewoverload, \addoverload, and a trailing \enddelim terminator.
ltMermaid / mermaid.sty and ltmermaid.sty (CTAN), last modified : 2026/04/16 (README in English)
- This repository provides two LaTeX packages to embed Mermaid diagrams: mermaid works with pdfLaTeX / XeLaTeX / upLaTeX / LuaLaTeX, while ltmermaid is a LuaLaTeX-native implementation. Both write diagram sources to disk, invoke the Mermaid CLI (mmdc) to render vector PDF files, and include the result with \includegraphics. -shell-escape and Mermaid CLI (mmdc or npx -y @mermaid-js/mermaid-cli) are required.

ua-jecon / ua-jecon.bst and ua-jecon.sty, last modified : 2026/04/21 (README in Japanese)
- A derivative of jecon.bst by Shiro Takeda, with several extensions for economics bibliography in Japanese. It also supports amsrefs-style compressed citations via the \acite command.
