This frequency informed the design, in fact. Easy to write, easy to read the last couple entries, moderate difficulty in finding older entries (in exchange for lower cost of making individual notes).
I think for me this is why it's so important for the system to be almost zero effort, else I'll just kinda stop using it. Just having an ubiquitous default place to dump something out of my brain helps.
Of note. A very slightly modified version of this runs on an ancient Thinkpad in my bedroom for diary/mental health reasons. I find the separation helpful. Those I almost never ever read, but I think that's the point of those.
Edit: at work I didn't really use this system, it's mostly for my own life. At work I used the ticket tracker, wikis, and calendar. I found that taking personal notes at work was best substituted by making actual documents that my team could find and use. There were much fewer uncategorized tasks at work.
I use them for cooking. I refer to this one every time I want to make a Pisco Sour cocktail, for example: https://til.simonwillison.net/cocktails/pisco-sour
I see notes as a way of accumulating micro-skills - things I know how to do, but not well enough to remember off the top of my head.
I have a channel where my various IOT devices tell me stuff, a channel where my algorithmic trading bot notifies me, and a reminders channel that basically serves as an append-only, always-synched memopad.
The main script is:
This script is accessible from all my personal machines as well as appropriate work machines. It works well enough. I've devised a small system of tags and keywords, but that part is not particularly interesting. I just put the keywords at the beginning of a line and search for them with /^thekeyword/.More structured notes go into dokuwiki or just a LibreOffice file in the project folder.
All this is almost guaranteed to be readable in 20 years. The LibreOffice files may be at more risk, but at least there is more than one tool available to read them.
