+how do you define a book collection?
+my book collection is the set of all books.
+
+i prefer physical books to e-readers.
+unfortunately i have quite a few these days.
+
+i want to read them all eventually!
+i also tend to live in quite small places
+and i want to be able to move city easily!
+
+so here's my system for organising my physical book collection.
+
+i want to:
+*   read books i already have
+*   read as many different books as possible
+*   minimise physical storage requirements
+*   keep track of books i've read
+*   gather books i don't already have
+
+constraints
+*   i don't know for sure what book i will want to read next
+
+for every book in the world
+*   i either have or have not read it
+*   i have access to it or i don't
+
+so i sort my book collection with 4 categories
+
+*-------------------*-----------------------*
+|                   |                       |
+|       unread      |          read         |
+|        have       |          have         |
+|                   |                       |
+|   37º2 le matin   |   L'Homme des Jeux    |
+|                   |                       |
+*-------------------*-----------------------*
+|                   |                       |
+|       unread      |         read          |
+|       haven't     |        haven't        |
+|                   |                       |
+|    Das Kapital    |      Frankisstein     |
+|                   |                       |
+*-------------------*-----------------------*
+
+i can then begin to optimise my collection.
+
+*   i do not have this book, and i have read it.
+*   i have this book, but i have not read it.
+*   i have this book, and i have read it.
+*   i do not have this book, but i have not read it.
+
+the books i am most interested in having nearby are unread ones, as i would like to read as many different books as possible.
+
+books i have already read i don't need nearby anymore.
+i might pass it on, or store it somewhere with less of a premium on space.
+i could also attempt to track where it is!
+
+based on my requirements and my categories, i create four lists for the books
+
+*   ready
+*   all done
+*   read and gone
+*   hunted
+
+that looks like a decent start to the system, so i suppose now i'll start collecting!
+
+so i'll use markdown lists in the format
+
+```
+* [x] author - title    # reading
+* [ ] author - title    # nearby
+```
+when collecting music i use artist - year - name
+however, publication year is an extra step that will slow data entry, so won't use this to start with - i have a lot of books
+
+i realised i had a gpt-4 sub and that it could look at pictures now so i gave it a go
+i fed it some photos and some formatting preferences and i got out perfect markdown lists
+
+```
+- [ ] Doctorow, Cory - Walkaway
+- [ ] Ferreira, Pedro G. - The Perfect Theory
+- [ ] Hadfield, Chris - An Astronaut's Guide to Life on Earth
+- [ ] Heinlein, Robert A. - Beyond This Horizon
+```
+
+books are lovely are great to look at, but the mishmash of fonts and presentation are a nightmare for indexing.
+now we have some good and lovely metadata :)
+this is an imperfect method, as the only way i can check it is still by combing through the physical books manually
+but it does let me target my combing after identifying problems in the index
+and in the meantime gives us a bunch of data to play with
+
+markdown lists also allow me to mark some items in a list
+this is looks flexible, so i think in my 'ready' list i will mark which book(s) i am currently reading
+
+```
+- [ ] Doctorow, Cory - Walkaway
+- [ ] Ferreira, Pedro G. - The Perfect Theory
+- [ ] Hadfield, Chris - An Astronaut's Guide to Life on Earth
+- [ ] Heinlein, Robert A. - Beyond This Horizon
+```
+
+the other lists i will leave unmarked for now, until i think of something to do with them.
+
+as for doing things with them, i wrote a [python script](#) which processes the data in the now-populated all-done and ready lists to yield some interesting (?) and fun (?) results?
+
+[example output](#)

+# RSS
+
+Really Simple Syndication (RSS) is an ancient file format for communicating updates over the Web, and my personal favourite.
+
+* [It's Time for an RSS Revival](https://www.wired.com/story/rss-readers-feedly-inoreader-old-reader/)
+
+### Stubs:
+
+* my curated feeds
+* reader applications
+
+## Technical Simplicity
+
+From a technical perspective, like [Gemini](gemini://gemini.circumlunar.space) [\(HTTP\)](https://gemini.circumlunar.space/) it's grokkable with a couple good reads of the specification.
+I wrote [a simple generator](https://ktyl.dev/blog/2022/6/3/rss.md)] for my blog posts, and am now working on [a simpler one](./feed.py) for the garden.
+To start with, I'd like to generate it as simply as possible, from just a directory structure, but I can already see I'd like to do more with it.
+
+I work predominantly in [Git](https://git-scm.com/) repositories, which, like a directory, or a garden, is tree-based.
+My blog's feed has a chronological hierarchy, but at present it's based on manually creating and naming folders.
+It's also very much a _published_ format, rather than a living one.
+This is silly!
+Instead, I'd like to structure my feed around a Git repository, as I think it'd be a much better descriptor of activity.
+
+## Managing YouTube Subscriptions
+
+There are many reasons to avoid the YouTube homepage, such as recommended videos or the accursed Shorts.
+YouTube publishes channel-specific RSS feeds, making it totally possible to circumvent its subscription system entirely - including having to make an account - and keep track of channels one enjoys with RSS feeds instead.
+Get a channel's ID:
+
+1. Go to the channel's page
+2. Go to the About section
+3. Share icon under Stats block
+4. Copy channel ID
+
+The channel's feed is available at `https://www.youtube.com/feeds/videos.xml?channel_id=CHANNEL_ID_HERE`.
