Vim Advanced Search and Replace. I too make heavy use of the Quickfix, and I think it is one of the most underrated feature of Neovim. #vim

Simplest hash functions. I wish every single technical blog post look so precise and so well laid out.

Adding guards to all the executables I use as makeprg, compiler, formatprg, etc. in my Neovim config files (mostly in after/ftplugin) to ensure portability across machines. While it is easy to detect language servers when they come as static binaries, some LSPs come as packages, e.g., R or Racket language servers. Here’s what I came with:

" after/ftplugin/r.vim
let output = system("Rscript -e '\"languageserver\" %in% installed.packages()'")
if v:shell_error == 0
lua <<EOF
vim.lsp.enable("r_language_server")
EOF
endif

" after/ftplugin/racket.vim
let output = system("raco pkg show racket-langserver | grep Checksum")
if v:shell_error == 0
lua <<EOF
vim.lsp.enable("racket-langserver")
EOF
endif

For other languages, I just use an if executable("<whatever>") test.

Trying out Helix today. It lasted a few hours until I got back to Neovim. Too much muscle memory, I guess, and I’m happy with my current hand-crafted config.

What I’m working toward is a canonical definition of the dataframe. Petersohn et al. made the best attempt I’ve seen with their data model and algebra. Category theory adds structure on top: three migration functors for schema-changing operations, and topos structure for set-theoretic reasoning within a schema. Together, these cover the relational core. — What Category Theory Teaches Us About DataFrames
