# Site TODO

**Note:** This is the `TODO.md` from the old Jekyll backend, so some of
this stuff may not make any sense.

## general
* replace `<img>` in old posts with `{{< figure >}}` (partial work
  done on stuff `>= 2019`)
* fix broken links in posts
* import files
* comment idea: http://donw.io/post/github-comments/
* add "music" somewhere ("songs", keep pmdn.org for personal stuff)
* add sticky footer:
  https://css-tricks.com/couple-takes-sticky-footer/
* enable mathjax for articles:
  https://bwaycer.github.io/hugo_tutorial.hugo/tutorials/mathjax/
  http://docs.mathjax.org/en/latest/output/svg.html
  (alternative, render mathjax as SVG via CLI)

    * dash is not /bin/sh on all linuxes (only debian-based distros)
    * wonder about overall size of base installs (base rate fallacy)
    * summary of rust conclusion seems suspect and different than
      content of paper itself
    * detailed results are interesting

  - CTEs as optimization barrier:
    https://old.reddit.com/r/programming/comments/suyidt/a_hairy_postgresql_incident/hxdvwl4/
  - `~* ANY(string_to_array(?))` (comment in reddit w/json array)
  - pub/sub?
  - domains instead of repeated check constraints
  - trigger `TG_ARGV`
  - trigger `REFERENCING ... AS` (newer PG)
  - `COMMENT ON` ...
  - `LISTEN/NOTIFY`?
- misc go cover improvements
  - add `title` and maybe `aria-label` attributes to relevant elements
  - add option to include external stylesheet?
* compare and contrast cyclonedx vs spdx
  - (at the moment i like cyclonedx more, it seems less ad-hoc)
  - https://cyclonedx.org/docs/1.4/json/
  - https://github.com/spdx/spdx-examples/blob/master/example3/spdx/example3-bin.spdx
  - go parsers for both are available:
    - https://github.com/spdx/tools-golang
    - https://github.com/CycloneDX/cyclonedx-go
