https://royfuwei.devA collection of technical notes and guides covering Node.js, Go, Nx Monorepo, Kubernetes (k8s) with Lens, PostgreSQL, and Docusaurus. Includes practical tips on process management in Node.js, slice pointers in Go, and CI/CD architecture.
Kubernetes uses a Master-Slave architecture to manage containerized applications. The hierarchy is structured as follows:
@docusaurus/plugin-content-blog plugin. To create blog posts, add Markdown files or folders to the blog directory. To co-locate images with a specific post, use a folder structure for that post. Blog post dates are automatically extracted from filenames using the format YYYY-MM-DD-title.md or by placing an index.md inside a folder named YYYY-MM-DD-title.# Example filename for date extraction
2019-05-30-welcome.md
# Example folder structure for co-locating images

Blog post dates are automatically extracted from filenames using the format YYYY-MM-DD-title.md (e.g., 2019-05-30-welcome.md) or from an index.md file within a dated folder (e.g., 2019-05-30-welcome/index.md). Using a folder for a post allows for easier co-location of images.commitlint and husky to automate the process.# Install dependencies
npm install commitizen --save-dev
npm install @commitlint/cz-commitlint --save-dev
# Initialize husky
npx husky-init && npm install
# Add the prepare-commit-msg hook to trigger Commitizen
npx husky add .husky/prepare-commit-msg 'exec < /dev/tty && node_modules/.bin/cz --hook || true'// Add to package.json

}Docusaurus blogging features are powered by the @docusaurus/plugin-content-blog plugin. To create blog posts, add Markdown files or folders to the blog directory.
Post dates are automatically extracted from filenames using the format YYYY-MM-DD-title.md (e.g., 2019-05-30-welcome.md) or from an index.md file within a folder named with the date (e.g., 2019-05-30-welcome/index.md). Using a folder for a post allows you to co-locate images with the content. Blog authors can be managed in the authors.yml file, and posts support tags.
!= true or NOT IN (true) will fail to return rows where the value is NULL because NULL comparisons result in UNKNOWN. To retrieve both false and null records, use an explicit OR condition with IS NULL.-- This will NOT return NULL values
SELECT * FROM foo WHERE ignored != true;
SELECT * FROM foo WHERE ignored NOT IN (true);
-- Correct way to get both False and Null
SELECT * FROM foo WHERE ignored = false OR ignored IS NULL;<button onClick={() => alert('button clicked!')}>Click me!</button>
