When I wrote that post, my blog was SSG generated by Pollen (which is ultimately running on the #Racket runtime). That was a great system and it served me well for years, but it had its shortcomings and eventually I decided to replace it with something simpler. I went with a dynamic #Lua site.
The new system is good old CGI based scripts written in #Lua using a #SQLite file as source of truth. About 1169 lines for the whole CMS including my #IndieAuth #Micropub and my #MetaWeblog endpoint.
