Crafting tools and products to help people think and create.

Hey, I’m Xiao, AKA Reorx on the internet. I'm a:

  • Full-stack web developer

    I have 6+ years of experience in full-stack web development, operations, and project management. I specialize in Python, Go, and JavaScript, but I don’t shy away from other languages to solve problems.

  • Freelancer

    I work from home to feed myself. I provide consulting services for creative workers and agencies to help them deliver better products. Meanwhile, I participate in profitable projects with my reliable partners.

  • Open-source enthusiast

    I’ve always been passionate about sharing the code and solutions I worked out. I maintain projects like Python libraries, Chrome Extensions, and Obsidian plugins on GitHub in my spare time.

  • and Product maker

    I’m now working full-time as the co-founder of a SaaS product that refines the way to collect and ingest information. It’s the first product I designed and built upon my own will. I’m excited to make it alive at the end of this year

Reorx’s Footprints is the Telegram Channel that aggregates the content I consume and create on the Internet. Join to get my updates and learn new things with me there.

The title immediately got my attention since I use UUIDs a lot in various projects, no matter personal or commercial.

Defeat VSCode Tab Bar

A while ago, I found my VSCode tab bar (or tool bar) UI was quite unstable. The reason was that extensions may add icons called “action button” on the right side of the tab bar according to the type of the file, so when switching back and forth between different kinds of files, these buttons will either show or hide, making the available spaces for tabs changing constantly. This may not be noticable when you just open a few tabs, but if you have tabs that are enough to take up the spaces of the tab bar, the whole tab bar will be a clown fiesta with the appearace and disappearance of the action buttons....
