I reverted the note number prefixes on both https://tech.zlliang.me and https://days.zlliang.me. Notes are now shown as #44 again instead of #tech44 or #days44.

I made the opposite change earlier this year because I thought the prefixes would make the two spaces clearer. After using them for a while, though, I found that they mostly added visual noise and mental overhead. The note number only needs to be unique within each site, so the extra prefix was solving a problem I don’t really have.
