π Hello, World!
This is a casual blog about AI, product design, and travel.
- Built with nextraΒ
- Deployed via Vercel
- Hosted on GitHub
- On PC, site development is done with VSCode, and Markdown content is edited with Typora
- On iPad, Working Copy is used to connect with the GitHub repository for content management, and Tiao is used for Markdown editing
The solution is basically free (I bought a domain for a better experience), stable in service, and offers good access speed both domestically and internationally. Itβs enjoyable to read on both PC and mobile. With git, multi-device synchronization and version management are possible. Writing on iPad is also a pleasure. Overall, Iβve found a solution Iβm quite satisfied with.
This site will be updated from time to time with insights from a product managerβs work, tool/product experience sharing, travel stories, and more. I hope it can be helpful or inspiring to you β€οΈ
