For Levi, Alex, the Kapo, was one of the most fearsome individuals in the Monowitz camp, even more so than the SS men. The SS had developed and honed the concentration camp system, starting in 1933 in Dachau. They developed the system to control and eventually break the prisoners. One of the methods used was to introduce camp prisoner functionaries who would have total powers over other prisoners. This had the benefits of reducing SS manpower needed to administer the camps but also of breeding division in the prisoner community.

The Kapo was the most feared of all prisoner camp functionaries. He was responsible for prisoner roll calls, overseeing the prisoner barracks, and supervising the prisoners at work. He literally had power of life and death over the prisoners. The Kapos were originally chosen from the German criminals (‘green triangles’) incarcerated in the concentration camps from the 1930s. They were chosen for their brutality and because they were German, and therefore separate from Jews, gypsies, and foreign political prisoners increasingly incarcerated in the concentration camps from 1941. Later in the war, Kapos were also chosen from the other prisoner communities including Jews, who could be equally as brutal as the German criminal Kapos.

Levi was correct to be afraid of ‘Alex, il Kapo’.

Subcamps of Auschwitz project

Levi explores the economy of cigarettes and smoking in the chapter of SQ entitled ‘Al di qua del bene e del male', where he explains that ‘Mahorca’, a low-quality tobacco, is officially distributed in the canteen in exchange for the coupons provided to the best worker, but because those coupons are distributed infrequently and inequitably, the tobacco is also sold unofficially in the Market, ‘in stretta obbedienza alle leggi dell’economia classica’, with the resulting booms and busts in price (OC I, 200-01). Because it can be exchanged for more food rations, newer clothing, and other vital necessities, ‘[f]ra i comuni Häftlinge, non sono molti quelli che ricercano di Mahorca per fumarlo personalmente; per lo più, esce dal campo, e finisce ai lavoratori civili della Buna’. That Deutsch is smoking during this work detail is thus a sign of his status and position within the camp.

Levi introduces the term ‘Häftling’ (pl. Häftlinge), German for ‘detainee’ or ‘prisoner,’ in the chapter of SQ entitled ‘Sul fondo,’ wherein he recounts his arrival in Auschwitz, a camp designed to produce ‘un uomo vuoto, ridotto a sofferenza e bisogno, dimentico di dignità e discernimento’, so that ‘Si comprenderà allora il duplice significato del termine «Campo di annientamento»’ (OC I, 152). It is immediately after offering this reflection that Levi provides the term used to denote this ‘uomo vuoto’: ‘Häftling: ho imparato che io sono uno Häftling. Il mio nome è 174 517; siamo stati battezzati, porteremo finché vivremo il marchio tatuato sul braccio sinistro’ (ibid.). Later in the same chapter, Levi explains the distinction between ‘Häftlinge privilegiati’ and ‘comuni Häftlinge’ and describes how the various groups of prisoners are distinguished: ‘Tutti sono vestiti a righe, sono tutti Häftlinge, ma i criminali portano accanto al numero, cucito sulla giacca, un triangolo verde; i politici un triangolo rosso; gli ebrei, che costituiscono la grande maggioranza, portano la stella ebraica, rossa e gialla’ (OC I, 158).

This is quite clever with respect the space of cards like Analog and 3x5 Life.

Cost of items purchased separately on Amazon: - Index cards (total of 6*31+13+12+52=263, so round up to 300 at $0.02 each) = $6.99 - storage box $16.49 - dividers $5.79 - phone sleeve: $2.32 - stainless steel stand: $2.33

Buying these in bulk for additional profit margin/branding could certainly lower the cost.

Their retail is $97.79 versus commercially at $33.92. Their actual cost at bulk is probably significantly less and likely closer to $15 all in for the system, so this is a nice little profit.

They apparently offer a mini course outlining the system.

One wonders how much "why" they offer?

Just like the imagery from the Analog System's promotion, this video features someone fed up with lots of notebooks pushing them off their desk in frustration—naturally to turn to index cards.

Review of the Analog productivity system. Quick overview with generally positive tenor.

The creator mentions that he collects productivity systems like Pokémon! A sort of affliction of shiny object syndrome in the productivity space.

Passing mention of Patrick Rhone's dash/plus system

The Analog system has a thin metal divider that separates two sections in the base. The broad suggestion is to use this space as storage and the divider for separating the blank stock of cards from used cards. One could also separate the next/someday cards from the today cards (new and finished).

The divider serves as a tabbed divider in many systems, but here there are only a total of three slots for differentiation: one slot for one card with today's list, and two other spaces for other cards that the user can determine their uses for. This definitely makes the system incredibly simple and minimal.

It's only slightly different from the old common Park Sherman Co. desk note pad systems which sometimes had a universal calendar and one tray space for notes.

Similar to the sorts of to do list task key in many bullet journals, the Analog system has "task signals" : - black filled circle means "complete task" - half filled circle means task is in progress - a right arrow in the circle means the task was delegated - a cross in the circle means that the task is an appointment, potentially with the appointment time added to the to do item

The system suggests that you can "create your own" task signals, though in true minimalist fashion, it doesn't give other suggestions. Presumably one could do other pattern fills of the circle or symbols within it to mean other things (example: bullet journal key symbols).

Interestingly, the to do circles start out not blank, but with a single thin line splitting the circle in half vertically. This is apparently a design choice, perhaps to make it easier to fill in half of the circle?

Though the Analog system clearly delineates cards of to do lists as "Today", "Next", "Someday", I've definitely seen this sort of delineation well before this system.

What other systems explicitly use this framing or similar framings?

While the today / next / someday cards are labeled, they're also color coded (white, light tan, tan) to help distinguish them.

Though not defined in the Analog system, these differently colored cards could also be used to indicate different sorts of data, though one would need to potentially ignore the pre-printed labels of "Today", "Next", "Someday".

The Analog system utilizes a simplified version of an Eisenhower matrix which we'll call "today / next / someday" as a means of prioritizing to do list items on a temporal basis.

Following a pattern seen in many modern wooden recipe card boxes to hold the current recipe one is working on, Jeff Sheldon has cut a long thin slot into his card holder to allow one to stand up today's card in the front as a means of displaying and featuring what needs to get done.

https://ugmonk.com/pages/analog

Jeff Sheldon describes how the Analog system works, generally following most of the outline of the Memindex method, but with some hints of the Bullet Journal method's notation.

https://www.kickstarter.com/projects/ugmonk/analog-the-simplest-productivity-system/posts

Analog Kickstarter dates: - wrapped on 2021-05-07 - funded on 2020-08-07 - launched on 2020-06-23

https://www.kickstarter.com/projects/ugmonk/analog-the-simplest-productivity-system

Jeff Sheldon's Analog productivity system is a physical product consisting of a wooden tray, metal divider, 3 x 5" custom printed index cards (and refills), a felt carrier, and other accessories which functions as a minimalistic version of the old Memindex.

The someday card is described as being not only for individual to do items, but "big picture" goals.

The video shows the productivity books which Sheldon used to help design his system including 99u's Manage Your Day-To-Day, Unsubscribe by Jocelyn K. Glei, The One Thing by Gary Keller, Getting Things Done by David Allen, Deep Work by Cal Newport, and Atomic Habits by James Clear.

I started making lists on index cards—you know the ones we used back in school.

Note the total lack of any referent to why we used to use index cards in school.

https://vimeo.com/420319231?embedded=true&source=vimeo_logo&owner=8885398

In addition to using the three dots on the Analog system's cards to indicate how much one accomplished (modest value), Jeff Sheldon suggests using them to "link cards together", though he doesn't suggest how one could or should do this. Presumably he means to use the possible dot patterns as a code, but then one only has 2^3 or 8 ways of doing this, so the number of possible links is incredibly low. Some of this seems related to edge notched cards, though here, there's no suggestion of punching holes in these cards, so sorting or finding these cards isn't necessarily easy unless one otherwise indexes them, a functionality which falls outside of the minimalist scope of the product.

To expand on this method he also, more profitably, suggests adding titles to cards in the blank line at the top which is also frequently used for dating cards.

You can find some basic top level or second level DDC listings online, but to get the full set of listings, you've got to subscribe to the system which is updated every few years, something only library systems and large publishers typically do. To give yourself an idea of how deep this rabbit hole goes the DDC 23 is four volumes long and each volume is in the 1,000 page range. The DDC 23 self-identifies as 0.25.4'31-dc22. For most categories DDC generally only goes as deep as the thousands place (like Finsler geometry) though others will go slightly deeper usually to designate locations/cities. Most libraries only categorize to the tenths place, and sometimes these numbers can be found on the copyright page of books, often with the DDC volume number. I mentioned the UDC in that piece, but didn't give any links, but you could try:<br /> - https://udcsummary.info/php/index.php?lang=en - https://udcc.org/index.php/site/page?view=subject_coverage - https://en.wikipedia.org/wiki/Universal_Decimal_Classification

Honestly, you're wasting time and making way more work for yourself to adopt one of these numbering methods for a Luhmann-esque zettelkasten. Try asking yourself this question: What benefits/affordances will I get in the long run for having my numbering system mirror the DDC or UDC? (Unless you can come up with a really fantastic answer, you're just making more work to look up headings/numbers on a regular basis.)

In practice the numbers are simply addresses so you can quickly find things again using your index. If you're doing threads of cards (folgezettel), you're going to very quickly have tangentially related ideas of things mixed together anyway. (As an example, I've got lots of science and even some anthropology mixed into my math section, so having DDC numbers on those would be generally useless at the end of the day.) If it helps, Nicolas Gatien has a pretty reasonable and short video which makes this apparent: https://www.youtube.com/watch?v=tdHH3YjOnZE.

reply to u/drogers8 at https://www.reddit.com/r/antinet/comments/13eyg8p/extended_numbering_and_why_use_outline_of/

Based on my research, Scott Scheper was the one of the original source for people adopting the Academic Outline of Disciplines. I've heard him say before that he recommends it only as a potential starting place for people who are new to the space and need it as a crutch to get going. It's an odd suggestion as almost all of the rest of his system is so Luhmann-based. I suspect it's a quirk of how he personally started and once moving it was easier than starting over. He also used his own ZK for showing others, and it's hard to say one thing in a teaching video when showing people something else. Ultimately it's hard to mess up on numbering choices unless you're insistent on using only whole numbers or natural numbers. I generally wouldn't suggest complex numbers either, but you might find some interesting things within your system if you did. More detail: https://boffosocko.com/2022/10/27/thoughts-on-zettelkasten-numbering-systems/ The only reason to have any standardized base or standardized numbers would be if you were attempting to have a large shared ZK with others. If this is your intent, then perhaps look at the Universal Decimal Classification, though a variety of things might also work including Dewey Decimal.

Luhmann mentions that he only wrote on one side so that he didn't need to physically remove notes from the box when searching it. There is a level of lost productivity if one needs to physically remove a card to read it and then replace it; this lost productivity is magnified if one uses their slip box regularly over the span of many years.

"The Scrum method" described here, similar to the Kanban method, the Memindex method, tickler systems, or other card index as productivity systems, seems to be a productized name for selling Post-it Notes.

Scrum method consists of a project broken down into "story" rows with "to do" items in columns which progress along to "in process", "to verify", and finally "done".

Other productized names (particular to the note taking space): Antinet zettelkasten, Linking Your Thinking, Second Brain, etc.

The Thesaurus Linguae Latinae used the Meusel system for creating Zettel by utilizing double folio sheets onto which they copied text in hectographic ink which can be reproduced by lithography before cutting them up into slips.

Done alphabetically and then secondarily by chronological time. (Indicated in a box on the top left of each slip.) The number of copies of each slip is written in the bottom left hand corner and circled.

Watts, Charles J. The Cost of Production. Muskegon, MI: The Shaw-Walker Company, 1902. http://archive.org/details/costproduction01wattgoog.

Short book on managing manufacturing costs. Not too much of an advertisement for Shaw-Walker manufactured goods (files, file management, filing cabinets, etc.). Only 64 pages are the primary content and the balance (about half) are advertisements.

Given the publication date of 1902, this would have preceded the publication of System Magazine which began in 1903. This may have then been a prototype version of an early business magazine, but with a single author, no real editorial, and only one article.

Presumably it may also have served the marketing interests of Shaw-Walker as a marketing piece as well.

Tangentially, I'm a bit intrigued by the "Mr. Morse" mentioned on page 109 who is being touted as an in-house consultant for Shaw-Walker.... Is this the same Frank Morse who broke off to form the Browne-Morse Co.? (very likely)

General instructions for using a Memindex

HOW IT IS USED <br /> Things to be done today, jot on face card. Things to be done tomorrow or next Friday, jot on card for that day. Things to keep before you until done, jot on opposite front card. A matter for January 10th jot on a short card put under the band till you return to your desk, then file next to card for January 10th when it will come out and refresh your memory.

Things to be done when in New York or Chicago jot on card "N" or "C." The new address of Mr. Jones, under "J." Ideas on advertising jot on card tabbed "adv." Things for your clerk to do, on his card , etc., etc. Retire today's card tonight, carrying forward things not completed and put next card in the file in has proved that almost back of pocket case. The alphabet enables one to index all jottings for instant reference. This system is very comprehensive yet perfectly simple. You soon the learn to depend on it every hour of every day.

Within the general instructions in a 1904 Memindex advertisement (next to an ad for "Genuine Edison Incandescent Lamps") we see the general ideas of indexing things into the future and carrying undone tasks forward, just as is done in the bullet journal method.

Geyers Stationer. “Memindex Advertisement.” Geyer’s Stationer: Devoted to the Interests of the Stationery, Fancy Goods and Notion Trades, September 15, 1904. https://www.google.com/books/edition/Geyer_s_Stationer/L507AQAAMAAJ?hl=en&gbpv=0

Howard L. Wilson of Rochester, NY named his vest pocket card index system the Memindex.

Poem from the inside back cover of a 1913 Memindex Catalog:

JUST JOT IT DOWN.

If you’re going to meet a man<br /> Jot it down<br /> If you’ve got a little plan<br /> Jot it down<br /> If you never can remember<br /> Your requirements for September<br /> ’Till October or November<br /> Jot ’em down.

If you’ve got a note to pay<br /> Jot it down<br /> If its due the first of May<br /> Jot it down<br /> If collections are so slow<br /> That to meet the note you know<br /> You must dun old Richard Roe<br /> Jot it down

If you have a happy thought<br /> Jot it down<br /> If there’s something to be bought<br /> Jot it down<br /> Whether duty calls or pleasure<br /> If you’re busy or at leisure<br /> It will help you beyond measure<br /> Jot it down

If there’re facts that you’d retain<br /> Jot ’em down<br /> If you’ve got to meet a train<br /> Jot it down<br /> If at work or only play<br /> If at home or far away<br /> In the night or in the day<br /> Jot it down

In a 1913 catalog for the Wilson Memindex, the company suggested putting to do items and one's schedule on one side of the card and potentially keeping one's accounts or a diary on the reverse side.

archived page: https://web.archive.org/web/20230310010450/https://www.ebay.com/itm/165910049390

Includes price lists

List of cards includes: - Dated tab cards for a year from any desired. - Blank tab cards for jottings arranged by subject. - These were sold in 1/2 or 1/3 cut formats - Pocket Alphabets for jottings arranged by letter. - Cash Account Cards [without tabs]. - Extra Record Cards for permanent memoranda. - Monthly Guides for quick reference to future dates. - Blank Guides for filing records by subject.. - Alphabet Guides for filing alphabetically.

Memindex sales brochures recommended the 3 x 5" cards (which had apparently been standardized by 1930 compared to the 5 1/2" width from earlier versions around 1906) because they could be used with other 3 x 5" index card systems.

In the 1930s Wilson Memindex Company sold more of their vest pocket sized 2 1/4 x 4 1/2" systems than 3 x 5" systems.

Some of the difference between the vest sized and regular sized systems choice was based on the size of the particular user's handwriting. It was recommended that those with larger handwriting use the larger cards.

By the 1930's at least the Memindex tag line "An Automatic Memory" was being used, which also gave an indication of the ubiquity of automatization of industrialized life.

The Memindex has proved its success in more than one hundred kinds of business. Highly recommended by men in executive positions, merchants, manufacturers, managers, .... etc.

Notice the gendering of users specifically as men here.

Features: - Sunday cards were sold separately and by my reading were full length tabs rather than 1/6 tabs like the other six days of the week - Lids were custom fit to the bases and needed to be ordered together - The Memindex Jr. held 400 cards versus the larger 9 inch standard trays which had space for 800 cards and block (presumably a block to hold them up or at an angle when partially empty).

The Memindex Jr., according to a price sheet in the 1930s, was used "extensively as an advertising gift".

The Memindex system had cards available in bundles of 100 that were labeled with the heading "Things to Keep in Sight".

Główna myśl tekstu:

Publiczna propaganda czasu wolnego powinna polegać [...] [na] stworzeniu przez państwo ogólnych warunków do wypoczynku, czyli na odpowiednim zorganizowaniu świata wokół nas, najlepiej tak, by wypoczynek mógł mieć, przynajmniej czasami i dla chętnych, wymiar wspólnotowy.

Tekst przedstawia problem braku odpowiedniego przeżywania czasu wolnego, naskórkowo omawia jego przyczyny i lakonicznie, przy pomocy banałów, przedstawia potencjalne rozwiązania.

Problem: nie potrafimy odpoczywać.

Przyczyna: zaniedbania systemowe, kapitalizm.

Wypoczynek jest wyzwaniem. Kapitalizm (system) mu nie sprzyja. Dodatkową przyczyną jest „huczenie świata”, a więc przebodźcowanie i ciągłe skupienie na powiadomieniach, przede wszystkim tych z mediów społecznościowych.

Rozwiązanie: działania systemowe, wynikające z narzuconych odgórnie ograniczeń (indywidualne praktyki są doraźne i mają mniejsze znaczenie). Wśród tych działań systemowych są: wspólnotowe zaangażowanie, wyższa edukacja, infrastruktura kulturalno-sportowa (obiekty), infrastruktura komunikacyjna (dojazd), zieleń.

• Title
  • Impacts of meeting minimum access on critical earth systems amidst the Great Inequality
• Abstract

• Paraphrase

  • The Sustainable Development Goals aim to improve access to resources and services, reduce environmental degradation, eradicate poverty and reduce inequality.
  • However, the magnitude of the environmental burden that would arise from meeting the needs of the poorest is under debate—especially when compared to much larger burdens from the rich.
  • The ‘Great Acceleration’ of human impacts was also accompanied by a ‘Great Inequality’ in using and damaging the environment.
  • To correct the great inequality, the authors define ‘just access’ to minimum energy, water, food and infrastructure.
  • The penality incurred for achieving just access in 2018, with existing inequalities, technologies and behaviours, would have produced 2–26% additional impacts on the Earth’s natural systems of climate, water, land and nutrients—thus further crossing planetary boundaries.
  • These hypothetical impacts, caused by about a third of humanity, equalled those caused by the wealthiest 1–4%.
  • Technological and behavioural changes thus far, while important, did not deliver just access within a stable Earth system.
  • Achieving these goals therefore calls for a radical redistribution of resources.

• The conclusion of this study is that the ultimate definition of justice is that all of us have a right to a stable planet.
• Earth System Boundaries are like doughnut economics and include social justice as well.
• Earth System Justice is a multi-dimensional definition of justice including:
  • justice among present nations, communities and individuals (Intragenerational Justice),
  • justice for future generations (Intergenerational justice),.
  • justice for other living things and Earth system stability (‘Interspecies Justice and Earth system stability’)

As humans we're good at separating things based on categories. The Dewey Decimal System systematically separates mathematics and history into disparate locations, but your zettelkasten shouldn't force this by overthinking categories. Perhaps the overlap of math and history is exactly the interdisciplinary topic you're working toward? If this is the case, just put cards into the slip box closest to their nearest related intellectual neighbor—and by this I mean nearest related to you, not to Melvil Dewey or anyone else. Over time, through growth and branching, ideas will fill in the interstitial spaces and neighboring ideas will slowly percolate and intermix. Your interests will slowly emerge into various bunches of cards in your box. Things you may have thought were important can separate away and end up on sparse branches while other areas flourish.

If you make the (false) choice to separate math and history into different "sections" it will be much harder for them to grow and intertwine in an organic and truly disciplinary way. Universities have done this sort of separation for hundreds of years and as a result, their engineering faculty can be buildings or even entire campuses away from their medical faculty who now want to work together in new interdisciplinary ways. This creates a physical barrier to more efficient and productive innovation and creativity. It's your zettelkasten, so put those ideas right next to each other from the start so they can do the work of serendipity and surprise for you. Do not artificially separate your favorite ideas. Let them mix and mingle and see what comes out of them.

If you feel the need to categorize and separate them in such a surgical fashion, then let your index be the place where this happens. This is what indices are for! Put the locations into the index to create the semantic separation. Math related material gets indexed under "M" and history under "H". Now those ideas can be mixed up in your box, but they're still findable. DO NOT USE OR CONSIDER YOUR NUMBERS AS TOPICAL HEADINGS!!! Don't make the fatal mistake of thinking this. The numbers are just that, numbers. They are there solely for you to be able to easily find the geographic location of individual cards quickly or perhaps recreate an order if you remove and mix a bunch for fun or (heaven forfend) accidentally tip your box out onto the floor. Each part has of the system has its job: the numbers allow you to find things where you expect them to be and the index does the work of tracking and separating topics if you need that.

The broader zettelkasten, tools for thought, and creativity community does a terrible job of explaining the "why" portion of what is going on here with respect to Luhmann's set up. Your zettelkasten is a crucible of ideas placed in juxtaposition with each other. Traversing through them and allowing them to collide in interesting and random ways is part of what will create a pre-programmed serendipity, surprise, and combinatorial creativity for your ideas. They help you to become more fruitful, inventive, and creative.

Broadly the same thing is happening with respect to the structure of commonplace books. There one needs to do more work of randomly reading through and revisiting portions to cause the work or serendipity and admixture, but the end results are roughly the same. With the zettelkasten, it's a bit easier for your favorite ideas to accumulate into one place (or neighborhood) for easier growth because you can move them around and juxtapose them as you add them rather than traversing from page 57 in one notebook to page 532 in another.

If you use your numbers as topical or category headings you'll artificially create dreadful neighborhoods for your ideas to live in. You want a diversity of ideas mixing together to create new ideas. To get a sense of this visually, play the game Parable of the Polygons in which one categorizes and separates (or doesn't) triangles and squares. The game created by Vi Hart and Nicky Case based on the research of Thomas Schelling provides a solid example of the sort of statistical mechanics going on with ideas in your zettelkasten when they're categorized rigidly. If you rigidly categorize ideas and separate them, you'll drastically minimize the chance of creating the sort of useful serendipity of intermixed and innovative ideas.

It's much harder to know what happens when you mix anthropology with complexity theory if they're in separate parts of your mental library, but if those are the things that get you going, then definitely put them right next to each other in your slip box. See what happens. If they're interesting and useful, they've got explicit numerical locators and are cross referenced in your index, so they're unlikely to get lost. Be experimental occasionally. Don't put that card on Henry David Thoreau in the section on writers, nature, or Concord, Massachusetts if those aren't interesting to you. Besides everyone has already done that. Instead put him next to your work on innovation and pencils because it's much easier to become a writer, philosopher, and intellectual when your family's successful pencil manufacturing business can pay for you to attend Harvard and your house is always full of writing instruments from a young age. Now you've got something interesting and creative. (And if you must, you can always link the card numerically to the other transcendentalists across the way.)

In case they didn't hear it in the back, I'll shout it again: ACTIVELY WORK AGAINST YOUR NATURAL URGE TO USE YOUR ZETTELKASTEN NUMBERS AS TOPICAL HEADINGS!!!

A good list of tactics to communicate about innovation. For example,

• publish blogs, guides, videos with concrete tips,
• create a pool of champions
• basic education programs that help solve problems on the job

One could also think about a "virtual innovation" lab approach ...

• Government policy innovation
• Public services innovation (including service design and digital)
• Science and technology — governments employ thousands of scientists, engineers and researchers. Labs can think of ways for them to become more effective.
• Management systems innovation — “innovate” how government innovates to build skills, capacity and culture.

The article speaks about that "Management systems innovation" -- the way howe we build skills, capacity and culture -- is a key element for successful attempts for governments to innovation.

Concentrating on these aspects -- howe we work together, how we develop skills and capacity -- might be the key ingredients for a future for the OpenLab -- and the future of the innovation activities.

Maybe we could start offering "services" from the "OpenLab" to managers and teams ...?

This seems to be the key element here: systems-thinking approach and thinking about our role within our departments.

This essay seems to be more about shiny object syndrome. The writer doesn't seem to realize any problems they've created. Way too much digging into tools and processes. Note the switching and trying out dozens of applications. (Dear god, why??!!) Also looks like a lot of collecting digitally for no clear goal. As a result of this sort of process it appears that many of the usual affordances were completely blocked, unrealized, and thus useless.

No clear goal in mind for anything other than a nebulous being "better".

One goal was to "retain what I read", but nothing was actively used toward this stated goal. Notes can help a little, but one would need mnemonic methods and possibly spaced repetition neither of which was mentioned.

A list of specific building blocks within the methods and expected outcomes would have helped this person (and likely others), but to my knowledge this doesn't exist as a thing yet though bits and pieces are obviously floating around.<br /> TK: building blocks of note taking

Evidence here for what we'll call the "perfect system fallacy", an illness which often goes hand in hand with "shiny object syndrome".

Too many systems bound together will create so much immediate complexity that there isn't any chance for future complexity or emergence as the proximal system is doomed to failure. One should instead strive for immediate and excessive simplicity which might then build with time, use, and practice into something more rich and complex. This idea seems to be either completely missed or lost in the online literature and especially the blogosphere and social media.

people had come up with solutions Sadly, despite thousands of variations on some patterns, people don't seem to be able to settle on either "one solution" or their "own solution" and in trying to do everything all at once they become lost, set adrift, and lose focus on any particular thing they've got as their own goal.

In this particular instance, "retaining what they read" was totally ignored. Worse, they didn't seem to ever review over their notes of what they read.

I was pondering about different note types, fleeting, permanent, different organisational systems, hierarchical, non-hierarchical, you know the deal.

Why worry about all the types of notes?! This is the problem with these multi-various definitions and types. They end up confusing people without giving them clear cut use cases and methods by which to use them. They get lost in definitional overload and aren't connecting the names with actual use cases and affordances.

I often felt lost about what to takes notes on and what not to take notes on.

Why? Most sources seem to have reasonable guidance on this. Make notes on things that interest you, things which surprise you.

They seem to have gotten lost in all the other moving pieces. Perhaps advice on this should come first, again in the middle, and a third time at the end of these processes.

I'm curious how deeply they read sources and which sources they read to come to these conclusions? Did they read a lot of one page blog posts with summarizations or did they read book length works by Ahrens, Forte, Allosso, Scheper, et al? Or did they read all of these and watch lots of crazy videos as well. Doing it "all" will likely lead into the shiny object syndrome as well.

This seems to outline a list of specifically what not to do and how not to approach these systems and "popular" blog posts that are an inch deep and a mile wide rather than some which have more depth.

Worst of all, I spent so much time taking notes and figuring out a personal knowledge management system that I neglected the things I actually wanted to learn about. And even though I kind of always knew this, I kept falling into the same trap.

Definitely a symptom of shiny object syndrome!

Thoughts on Zettelkasten numbering systems

I've seen variations of the beginner Zettelkasten question:

"What happens when you want to add a new note between notes 1/1 and 1/1a?"

asked at least a dozen times in the Reddit fora related to note taking and zettelkasten, on zettelkasten.de, or in other places across the web.

Dense Sets

From a mathematical perspective, these numbering or alpha-numeric systems are, by both intent and design, underpinned by the mathematical idea of dense sets. In the areas of topology and real analysis, one considers a set dense when one can choose a point as close as one likes to any other point. For both library cataloging systems and numbering schemes for ideas in Zettelkasten this means that you can always juxtapose one topic or idea in between any other two.

Part of the beauty of Melvil Dewey's original Dewey Decimal System is that regardless of how many new topics and subtopics one wants to add to their system, one can always fit another new topic between existing ones ad infinitum.

Going back to the motivating question above, the equivalent question mathematically is "what number is between 0.11 and 0.111?" (Here we've converted the artificial "number" "a" to a 1 and removed the punctuation, which doesn't create any issues and may help clarify the orderings a bit.) The answer is that there is an infinite number of numbers between these!

This is much more explicit by writing these numbers as:<br /> 0.110<br /> 0.111

Naturally 0.1101 is between them (along with an infinity of others), so one could start here as a means of inserting ideas this way if they liked. One either needs to count up sequentially (0, 1, 2, 3, ...) or add additional place values.

Decimal numbering systems in practice

The problem most people face is that they're not thinking of these numbers as decimals, but as natural numbers or integers (or broadly numbers without any decimal portions). Though of course in the realm of real numbers, numbers above 0 are dense as well, but require the use of their decimal portions to remain so.

The tough question is: what sorts of semantic meanings one might attach to their adding of additional place values or their alphabetical characters? This meaning can vary from person to person and system to system, so I won't delve into it here.

One may find it useful to logically chunk these numbers into groups of three as is often done using commas, periods, slashes, dashes, spaces, or other punctuation. This doesn't need to mean anything in particular, but may help to make one's numbers more easily readable as well as usable for filing new ideas. Sometimes these indicators can be confusing in discussion, so if ever in doubt, simply remove them and the general principles mentioned here should still hold.

Depending on one's note taking system, however, when putting cards into some semblance of a logical sort-able order (perhaps within a folder for example), the system may choke on additional characters beyond the standard period to designate a decimal number. For example: within Obsidian, if you have a "zettelkasten" folder with lots of numbered and named files within it, you'll want to give each number the maximum number of decimal places so that when doing an alphabetic sort within the folder, all of the numbered ideas are properly sorted. As an example if you give one file the name "0.510 Mathematics", another "0.514 Topology" and a third "0.5141 Dense Sets" they may not sort properly unless you give the first two decimal expansions to the ten-thousands place at a minimum. If you changed them to "0.5100 Mathematics" and "0.5140 Topology, then you're in good shape and the folder will alphabetically sort as you'd expect. Similarly some systems may or may not do well with including alphabetic characters mixed in with numbers.

If using chunked groups of three numbers, one might consider using the number 0.110.001 as the next level of idea between them and then continuing from there. This may help to spread some of the ideas out as surely one may have yet another idea to wedge in between 0.110.000 and 0.110.001?

One can naturally choose almost any any (decimal) number, so long as it it somewhat "near" the original behind which one places it. By going out further in the decimal expansion, one can always place any idea between two others and know that there will be a number that it can be given that will "work".

Generally within numbers as we use them for mathematics, 0.100000001 is technically "closer" by distance measurement to 0.1 than 0.11, (and by quite a bit!) but somehow when using numbers for zettelkasten purposes, we tend to want to not consider them as decimals, as the Dewey Decimal System does. We also have the tendency to want to keep our numbers as short as possible when writing, so it seems more "natural" to follow 0.11 with 0.111, as it seems like we're "counting up" rather than "counting down".

Another subtlety that one sees in numbering systems is the proper or improper use of the whole numbers in front of the decimal portions. For example, in Niklas Luhmann's system, he has a section of cards that start with 3.XXXX which are close to a section numbered 35.YYYY. This may seem a bit confusing, but he's doing a bit of mental gymnastics to artificially keep his numbers smaller. What he really means is 3000.XXX and 3500.YYY respectively, he's just truncating the extra zeros. Alternately in a fully "decimal system" one would write these as 0.3000.XXXX and 0.3500.YYYY, where we've added additional periods to the numbers to make them easier to read. Using our original example in an analog system, the user may have been using foreshortened indicators for their system and by writing 1/1a, they may have really meant something of the form 001.001/00a, but were making the number shorter in a logical manner (at least to them).

The close observer may have seen Scott Scheper adopt the slightly longer numbers in the thousands (like 3500.YYYY) as a means of remedying some of the numbering confusion many have when looking at Luhmann's system.

Those who build their systems on top of existing ones like the Dewey Decimal Classification, or the Universal Decimal Classification may wish to keep those broad categories with three to four decimal places at the start and then add their own idea number underneath those levels.

As an example, we can use the numbering for Finsler geometry from the Dewey Decimal Classification wikipedia page shown as:

``` 500 Natural sciences and mathematics

510 Mathematics

    516 Geometry

        516.3 Analytic geometries

            516.37 Metric differential geometries

                516.375 Finsler geometry

```

So in our zettelkasten, we might add our first card on the topic of Finsler geometry as "516.375.001 Definition of Finsler geometry" and continue from there with some interesting theorems and proofs on those topics.

Of course, while this is something one can do doesn't mean that one should do it. Going too far down the rabbit holes of "official" forms of classification this way can be a massive time wasting exercise as in most private systems, you're never going to be comparing your individual ideas with the private zettelkasten of others and in practice the sort of standardizing work for classification this way is utterly useless. Beyond this, most personal zettelkasten are unique and idiosyncratic to the user, so for example, my math section labeled 510 may have a lot more overlap with history, anthropology, and sociology hiding within it compared with others who may have all of their mathematics hiding amidst their social sciences section starting with the number 300. One of the benefits of Luhmann's numbering scheme, at least for him, is that it allowed his system to be much more interdisciplinary than using a more complicated Dewey Decimal oriented system which may have dictated moving some of his systems theory work out of his politics area where it may have made more sense to him in addition to being more productive on a personal level.

Of course if you're using the older sort of commonplacing zettelkasten system that was widely in use before Luhmann's variation, then perhaps using a Dewey-based system may be helpful to you?

A Touch of History

As both a mathematician working in the early days of real analysis and a librarian, some of these loose ideas may have occurred tangentially to Gottfried Wilhelm Leibniz (1646 - 1716), though I'm currently unaware of any specific instances within his work. One must note, however, that some of the earliest work within library card catalogs as we know and use them today stemmed from 1770s Austria where governmental conscription needs overlapped with card cataloging systems (Krajewski, 2011). It's here that the beginnings of these sorts of numbering systems begin to come into use well before Melvil Dewey's later work which became much more broadly adopted.

The German "file number" (aktenzeichen) is a unique identification of a file, commonly used in their court system and predecessors as well as file numbers in public administration since at least 1934. We know Niklas Luhmann studied law at the University of Freiburg from 1946 to 1949, when he obtained a law degree, before beginning a career in Lüneburg's public administration where he stayed in civil service until 1962. Given this fact, it's very likely that Luhmann had in-depth experience with these sorts of file numbers as location identifiers for files and documents. As a result it's reasonably likely that a simplified version of these were at least part of the inspiration for his own numbering system. † ‡

Your own practice

At the end of the day, the numbering system you choose needs to work for you within the system you're using (analog, digital, other). I would generally recommend against using someone else's numbering system unless it completely makes sense to you and you're able to quickly and simply add cards to your system with out the extra work and cognitive dissonance about what number you should give it. The more you simplify these small things, the easier and happier you'll be with your set up in the end.
