      Creating world fields (groups of words related to a particular area or field of knowledge) can be helpful for acquiring vocabulary in a new language. There's no research here to back up the claim, but it's an interesting word game and method for familiarize oneself with a small area and acquire new words related to an area or various related stem words.

    1. Guard fields proved invaluable for breaking cycles[5], a central anxiety of early hypertext [18][11].

      Storyspace used a scripting language to create what they called "Guard Fields" — boolean logic that will make a link clickable or not based on the pages the reader had already visited up until that point.

      What is interesting is that guard fields proved effective at breaking cycles (one of the risks of disorientation in hypertext).

    1. It's not customizable enough and there aren't enough distinct fields for inevitably complex work tasks. Google Sheets fixes that. No, it's not a to do list app, but that's why I love it. It's an app I already use. It's extremely customizable.

    1. So the main thing this gives us is a way to set indeterminate property of input via an indeterminate property?

      This is misnamed. Doesn't actually give us a tri-state checkbox. Just a binary checkbox.

    1. input.indeterminate = indeterminate

      So the main thing this gives us is a way to set indeterminate property of input via an indeterminate property?

      Not sure how that supposedly gives us a tri-state checkbox.

    1. ‘supra-disciplinary’ character.

      Rhetoric, too, is a supra-disciplinary field, to the extent that it's sometimes mistaken as not even having a 'subject' (re: the protest that you can't teach writing until students have enough of a subject to write about under their belts first).
