  1. Overview of PlistBuddy for macOS

    PlistBuddy is a built-in macOS command-line utility used to parse and edit .plist files (property lists). It is particularly useful for modifying binary plist files that are not readable by standard text editors. Because PlistBuddy is not in the default system PATH, it must be called using its absolute path: /usr/libexec/PlistBuddy.
    /usr/libexec/PlistBuddy --help

  2. Overview of recommended single-player mobile games

    A collection of recommended single-player mobile games focusing on story-driven, RPG, and puzzle-solving experiences. The list emphasizes games with strong narratives, unique art styles, and immersive worlds over competitive multiplayer titles.

  3. Overview of Lashi WordPress Theme

    Lashi is a minimalist, responsive WordPress theme ported from the Typecho Lashi theme. It is designed for high performance and efficiency, featuring a layout inspired by the Lashi theme, side menus from the Mirages theme, and a top focus bar and side toolbar from Adams. It shares some backend settings and logic with the Fengluan theme but is optimized for better resource usage (lower CPU/fan usage).

  4. Overview of Fengluan (凤鸾) WordPress Theme Features

    The Fengluan (凤鸾) theme is a multi-functional responsive WordPress theme. It includes a wide array of built-in features for homepage customization, user management, and content presentation.

  5. Overview of Lareina WordPress Theme

    Lareina is a minimalist, single-column WordPress theme designed for readability, specifically suited for content heavy with text, code, and images. It is built using Nuxt.js with Server-Side Rendering (SSR) to overcome the SEO and initial load time limitations of standard Vue Single Page Applications (SPAs), leveraging the WordPress REST API for data fetching.

  6. Overview of the New BiliBili Toolbox

    The New BiliBili Toolbox is a tool designed for downloading Bilibili videos (specifically those with standard AV numbers). It features a decoupled frontend and backend architecture where PHP handles authentication, database interactions, and Bilibili data retrieval, while the frontend is built with Vue and Element-UI.

    Key capabilities include:

    • Direct browser downloads.
    • Integration with aria2 for automated downloads.
    • Support for IDM (Internet Download Manager) on Windows.
    • A completely rewritten login and registration system.

  7. Overview of recommended macOS productivity and system utilities

    A collection of useful macOS applications for various tasks:

    • MindNode: Mind mapping tool with iCloud sync for outlines and conceptualization.
    • Pages: Word processing software by Apple.
    • PopClip: Efficiency tool that provides shortcut buttons (e.g., search) when text is selected.
    • Magnet: Window management tool for snapping windows to edges and splitting screens.
    • Amphetamine: Prevents the Mac from automatically sleeping or turning off the display.
    • Snap: Allows opening Dock applications using Command + [Number] shortcuts.
    • IINA: Free and open-source modern video player.
    • AirServer: AirPlay receiver to mirror iPhone screens to the Mac.

  8. Use Mobile Theme Switcher to automatically switch WordPress themes based on device OS

    The Mobile Theme Switcher plugin for WordPress allows administrators to serve different themes based on the visitor's operating system and version. This is particularly useful for serving a lightweight 'minimal' theme to older devices (e.g., iOS versions below 9 or Android versions below 5) to improve performance and reduce lag.

  9. Build a blog system with Nuxt.js and Express

    The author developed a custom blog system using Nuxt.js for the frontend and Express for the backend to replace a WordPress setup. The architecture leverages Nuxt's server-side rendering and Express's efficiency. The database schema is loosely modeled after WordPress to facilitate data migration but includes custom modifications for specific features like 'Moments' and password-protected articles.

  10. Understand Skew Stickiness Ratio (SSR) concepts

    The Skew Stickiness Ratio (SSR) quantifies how volatility skew behaves relative to two extreme models when the underlying asset price moves:

    • Sticky Delta: The implied volatility (IV) of an option with a specific Delta remains constant regardless of the underlying price change. In this case, the skew remains unchanged.
    • Sticky Strike: The IV of an option with a specific strike price remains constant. As the underlying price moves, the strike price that corresponds to a specific Delta changes, causing the Delta-measured skew to change.

    SSR measures where the actual market behavior falls between these two extremes.

  11. Lareina Update 2 Feature Overview

    Lareina Update 2 introduces several performance and UX enhancements, including site-wide image lazy loading, an image lightbox, and a redesigned footer with breadcrumb navigation. Key functional updates include auto-saving for new articles to prevent data loss, improved navigation where previous/next articles are selected from the same category, and the addition of website access speed statistics. The update also introduces support for custom global CSS.

  12. Troubleshoot MathJax with Server-Side Rendering (SSR) in Nuxt

    MathJax relies on the window object, which is unavailable during server-side rendering (SSR) in frameworks like Nuxt. To avoid errors, do not install MathJax via npm for SSR; instead, load the JS file dynamically in the browser and then initialize the configuration and rendering queue.
