-   More and more I would like to learn [[Racket]].

-   I'm encountering increasingly frequent slowdowns and annoyances in [[Emacs]] of late.  I think mostly when I'm working in [[org-roam]].  It seems pretty buggy - possibly just due to my config.  But it doesn't find files that I know exist, it slows down massively when processing the DB.
    -   Ah - so not finding files might have been due to my use of a relative path in dir-locals.
    -   I seem to have to keep on running `org-roam-db-clear` and `org-roam-db-build-cache` of late.  Hope I've got it sorted now.
    -   I am also getting big, annoying interruptions from this background process that runs to update the DB.  `org-roam-db-update-method` is set to `'idle-timer`, and `org-roam-db-update-idle-seconds` by default is set to 2.  I think I'll try changing the method first to `'immediate`.  If that is still no good, I'll change back to idle timer but with a increased number of seconds.
    -   immediate works a bit better for me, because I'm more likely to naturally pause after saving a file, so the brief processing time doesn't bother me as much.
    -   Still, would be good to see if the time for updating the DB could be reduced.

-   A [[spaced repetition]] approach that might work with org-roam: [The Poor Org-User Spaced Repetition - Where parallels cross](https://ag91.github.io/blog/2020/09/04/the-poor-org-user-spaced-repetition/)

-   Removed [[helm]] duplicates, that was getting a bit annoying. https://github.com/syl20bnr/spacemacs/issues/13564

-   My [[spacemacs]] config is getting a bit unwieldy.  I'd quite like to do that org-babel literate config thing that people do.  But probably a bit of a unnecessary yak shave right now.
    -   Decided to shave that yak.  Not too bad. [[Setting up a spacemacs literate config file]].

-   I'd like to the issue on [[Flock]] where reloading a page with stacked notes sometimes gives a 'page not redirecting correctly' error.
    -   Also some links from subfolders don't work.

-   Definitely enjoyed the [[Literate config]] approach for my spacemacs config.  It probably makes sense for config - stuff that is cobbled together over time from various sources.  Was thinking about if it would be worth trying it with other code - i.e. [[Literate programming]].  It could be problematic on shared projects though, presumably - you'd be forcing everyone in to doing it that way, otherwise your literate file and the code would get out of sync.

-   [[Adding timestamps to org-roam notes]].

-   `toggle-debug-on-error` is very handy.  Used it today a few times when fixing things broken in my config or elsewhere.

-   Been trying to get [[org-roam-server]] to work.  It's super slow on my graph.  Also tried org-roam-server-light but it's just the same performance issue on the client-side.  Also I can't seem to get it to filter out the Recent Changes page annoyingly, despite putting it in the exclude filters.
