Notes on Mar 18, 2026

I just removed note tags from both https://tech.zlliang.me and https://days.zlliang.me.

While writing notes, I kept thinking about how tags should be organized. Sometimes I would spend quite a while deciding which tags to use, and that gradually turned them into a writing burden instead of a helpful tool. I found that tags are simply hard to plan well and maintain over the long term. On top of that, after adding search to notes a few days ago, part of the original value of tags was already covered. I would rather leave tags out for now and add them back only after I find a better way to organize notes.

Along the way, I also simplified the sidebar and reworked the /notes/types index page. The sidebar is now flatter and quieter, and the type index uses richer cards with counts and short descriptions.

The main commit is zlliang/zlliang@8381e33, a cleanup and simplification pass across both sites that removed tags, flattened the sidebar, and improved how note types are presented. Most of the code was written with the help of the Codex app.

Update Mar 22, 2026: Removing tags also removed their old URLs, so I later added middleware handling for those legacy routes. Old tag pages now return 410 Gone while the other migrated note URLs keep working through redirects, which should make the cleanup clearer to search engines.

Update Mar 30, 2026: In late March, I renamed my two journal websites. They are now Hack https://hack.zlliang.me and Muse https://muse.zlliang.me. See: Renamed the two journal websites to Hack and Muse.

I have removed the world map from my landing page for now.

When I added it in February, I liked the idea: a compact visual trace of the places I have been, with links to travel posts when I had written one. But after living with it for a while, I kept feeling that the interaction was not good enough. It looked more interesting than it actually felt to use.

So I decided to simplify the page again. I would rather leave something out than keep a feature that feels half-finished. If I come up with a better concept and can polish it properly, I may bring it back in another form.

Introducing GPT-5.4 mini and nano1. OpenAI finally refreshed its smaller and cheaper models. The previous mini/nano release was GPT-5 in August 2025, while GPT-5.1-Codex-Mini in November 2025 was a more coding-specific branch.

It feels like OpenAI is gradually tidying up its model lineup. At least in the GPT-5.4 family, there is no separate “Codex”-suffixed specialized model, and the mini and nano variants seem to be catching up too.

I checked the Codex app this morning and saw that its built-in subagents are already using GPT-5.4 Mini.
