Swimming with Ideas

This is another installment of the What Are You Working On? thread. Add to this thread by telling us what is happening in and around your ZK journey. Join the community and enlighten us about your knowledge path trajectory. I do this for selfish reasons. It helps me clarify my goals and visualize my thinking. And sometimes, a conversation sparks an idea worth exploring.

Ideas I'm exploring with my ZK:

Workouts and exercise programs for a 67-year-old who wants his final decade to be active.
I'm tweaking my ZK Dashboard. I'm trimming information that is distracting and reformating some, so it is more engaging. This is an iterative process. This work fits my personality.
I'm seriously thinking of restarting my ZK fresh. So far, the disadvantages outweigh the benefits, but the difference is getting closer to a tipping point.

Things I'm reading:

Morris, Mary. My ideal bookshelf. 2012.
Attia, Peter. Outlive: the science & art of longevity. 2023.
Calvino, Italo. The road to San Giovanni. 1994.
Calvino, Italo. Difficult loves. 2017.
Manguel, Alberto. A history of reading. 2014.
Davis, Lydia. Essays one. 2020.

Music I'm listening to:

Lofi Girl
Carla Bley
Darkside
Hana Rani Live from Studio 52

The "My rolling ten-day zettel production" is produced by a script for attachment to my daily journaling template. I do my journaling in Bear to keep personal journaling separate from my knowledge work.

Let me know if you would like to discuss any of these notes.

My ten day zettel production

Jeffrey · November 2023

Peter Attia - Outlive is a real gem! Pre-ordered it back when it came out. Should be a mandatory read for most people!

Will · November 2023

@Jeffrey, fill us in on how the week has been working in your ZK. What are you reading now? How is your ZK journey going?

ctietze · November 2023

The past weeks have been a flurry of macOS observations, edge case fixes, compatibility tests, and learning about higher-level programming concepts more. Like, what's the opposite of "polymorphism"? "Monomorphism"? That's hardly used, it seems.
Finished reading Lion Feuchtwanger: Success. Disturbing novel about the ~1920's and first rise of Hitler.
Working on the last stretch of The Archive plugin integration, and checking out what the JavaScript engine is capable of. Logging progress on this last mile here.

I wonder what our mathematicians like @ZettelDistraction do with and think of Martin-Löf Type Theory. It appears to be a formalization to write different things in a unified way using a shared (mathematical) notation. The foundational ideas don't appear new to me, though. But I'm too slow and unexperienced with that to make any informed claim.

Unbelievable! - What will be better with your new ZK? Any new design principles, a better workflow, a new and better tool?

Edmund · November 2023

This week I’m still in an “Inspect and Adapt” phase. The formal productivity rate is very low.

Things I'm reading:

Morris, Mary. My ideal bookshelf. 2012.

The title sounded interesting, so I looked it up. Mary Morris seems to be a writer, but I can't find a book written by her with that title. Is it this book: https://www.goodreads.com/en/book/show/13528388 ?

Will · November 2023

@boxcariii, sorry for the confusion. Yes, you've hit on the right book. Jane Mount is the illustrator and co-editor of this book. You've pointed out a problem I have with the Keyboard Maestro macro I use to get a list of Zotero citations. I'll have to look closer at this. The correct reference should be:

Mount, Jane, and Thessaly La Force, editors. My Ideal Bookshelf. First edition, Little, Brown and Company, 2012.

The other book citations are correct.

The book is a quick read and a vicarious look at the books that influenced others. I was led to this book by the reference from An ‘Ideal’ Book About Books Every Book Lover Needs to Read that went, "It is a sign I've done a poor job of choosing my friends if no books are displayed when I visit their home for the first time."

Also, him calling the ZK a septic tank should be revealing that it's quite expected that you won't produce gold every day.

I also found that the early notes from 2009--2012 are not that useful to me. In part because the topics don't come up as often, and if they do, the learnings are put in a weird way. It got better after 2012, but I prefer 2018 and newer still

It looks like your goals are changing. I'm not in this situation yet, but have some ideas how to deal with a changed focus in my Zettelkasten. My favorite concepts are: Agile [1] and KonMari [2]

So I‘m highly interested to learning from your experiences.

GeoEng51 · November 2023

@Will I've tried to be selective in what goes into my Zettelkasten, with the view of it being useful to my future self or my family. But guess what - it's just a reflection of the state of my mind and what boils to the surface at different times. It's of varying quality and astuteness, and yes, even of varying usefulness. And of course it evolves, it's always a "work in progress". I'm sure even if it was suited to my tastes and needs, to me - to another, it would be a bowl of swill.

Are you perhaps being too hard on yourself? Does your current feeling about your Zettelkasten come from the ratio of effort put in to perceived benefit coming out? As @Edmund , I'll be interested in your journey on this, if you keep us informed (and enlightened). Don't be hasty, though! You've created something wonderful, no matter how you feel about it at the moment.

This puts me in good company—you and Luhmann. I realized that I had become disillusioned with some of my ZK notes. Each note lies on the spectrum of being inspirational, and they move around on that spectrum. I tend to get frustrated when I tend to notice that my notes are not on the part of the spectrum that has the sun shining on them.

Feeling a passing mood, just reporting it. I don't want to make too big a deal of it. What triggered this was a look at Maggie Appleton's Digital-gardeners: Resources, links, projects, and ideas for gardeners tending their digital notes on the public interwebs and the intersection of a renewed idea of working with the garage door open. Which is what I'm trying to do here with this ongoing thread.

I live under an avalanche of books. My friends and I agreed to avoid visiting each other. I'm setting up another computer this week for writing in bed, in case I'm too lazy to make it to the Monastic Study Alcove, modeled after the Juanqinzhai 倦勤斋, or the "Studio of Exhaustion From Diligent Service", which is a hall in the Palace of Tranquil Longevity built by the aging Qianlong Emperor as part of his retirement suite. But here is a Zettel.

It's deja vu all over again -- Yogi Berra. My notes on compiling SageMath from source code leave something to be desired. Since I've hit the same missing library error I always encounter when compiling SageMath with R, I have more notes to add to the ZK on SageMath 10-1, which I need for a Jupyter notebook to add to Operations Tensorielles Simpliciales, which is itself part of a larger project.

ZettelDistraction · November 2023

If you have been compiling SageMath 10.1 from source this Thanksgiving weekend--and I know you have--you might be interested in the following note.

Install Python 3.10.4 from source

The last stable release of Python is 3.10.4 as of the time of this writing. This version does not have the Cython defect of 3.11+. That defect was repaired in 3.12+, but Sage 10.1 isn't compatible with Python 3.12+ and won't be until Sage 10.3.

Download the Python source from
Index of /ftp/python/3.10.4/

Untar somewhere, cd to the Python-3.10.4 directory and run

./configure --enable-optimizations
sudo make -j4 && sudo make altinstall

Then run the following.

sudo update-alternatives --install /usr/bin/python python /usr/local/bin/python3.10 1
sudo update-alternatives --config python

In $HOME/sage, run python3.10 -m venv local. Activate the virtual environment, then run the make configure, source ../minimal_sage.sh and run make build from the sage-10.1 subdirectory.

This works since setuptools could not install with later versions of Python.

Compile R with --nolock

The latest R source is R-4.3.2.tgz. Use this. The default installation directory is /usr/local. Need to make install as root and chown to flengyel:flengyel. Then create /usr/local/lib/R/site-library, or numerous errors occur with sage-10.1 make build.

options(repos=c(CRAN="https://cran.wustl.edu/"))
repos <- "http://cran.wustl.edu"
lib.loc <- "/usr/local/lib/R/site-library"
install.packages('pacman', repos, dependencies=TRUE, INSTALL_opts='--no-lock')
mypks <- pacman::p_lib()
saveRDS(mypks, "~/mypks.rds")
mypks <- readRDS("~/mypks.rds")
install.packages(mypks, lib.loc, repos, dependencies = TRUE, INSTALL_opts = '--no-lock')

We need to run

devtools::install_github('IRkernel/IRkernel')

However, I needed to install.packages('devtools') which failed due to a missing dependency corrected with install.packages('stringi').

then finally devtools::install_github('IRkernel/IRkernel'). This led to

Using github PAT from envvar GITHUB_PAT
Error: Failed to install 'IRkernel' from GitHub:
  Timeout was reached: [api.github.com] Resolving timed out after 10000 milliseconds

Resolve DNS for api.github.com (DONE), and regenerate API token (DONE)

Regenerated token for R: ghp_censoredsAlP0oGLm8

The GitHub Personal Access token can be regenerated at:

https://github.com/settings/tokens/1262267121

A specific environment variable needs this during the IRkernel installation within R: GITHUB_PAT from above.

 Sys.getenv("GITHUB_PAT")
[1] "ghp_invalid3J3qPPFRYn5JPBbOUiH2j5mbm"

 Sys.setenv(GITHUB_PAT = "ghp_censoredygJmJMbuEOsAlP0oGLm8")
 Sys.getenv("GITHUB_PAT")
[1] "ghp_censoredgJmJMbuEOsAlP0oGLm8"
 devtools::install_github('IRkernel/IRkernel')

Then IRkernel::installspec(). Looks like this did the trick

I claim to be an introvert, so friends know I'll be terrible company and not visit and interrupt my reading.
It sounds like you're having a quiet, relaxing weekend slaying the dragon.

I'm grateful to have you as a friend.

It sounds like you're having a quiet, relaxing weekend slaying the dragon.

It's still snorting, deploying sulphuric farts (a noxious phenomenon well-known in ancient lore but airbrushed out of the modern, multi-volume heroic adventure chronicle), and coughing up embers. Then I must do the same on another computer dragon, installed on a shelf in the bedroom, once the first succumbs to the command line.

I'm grateful to have you as a friend.

Aw shucks, @Will. Likewise.

ZettelDistraction · November 2023

@Will

This is the Internet premier of a rare, suppressed engraving of such a dragon unleashing its sulphuric flatulence while perched atop a city. It's about time that fantasy fans knew the truth.

Here's another, more frank depiction. No one slayed dragons for their gold. The ancients slayed dragons to clear the air, as I am attempting now by making these vital engravings public.

ZettelDistraction · November 2023

@Will. The dragon of sulphuric incontinence is still active.

But this is easily rectified--or "rectumfied."

I get serious PTSD from skimming the notes of this setup procedure. (I really hate installing weird open source stuff from the command line, because I eventually forgot to copy one or more steps to my setup instructions Zettel, so next time I want to upgrade the software, I break something. Which often means: everything.)

@ctietze said:

The installation on the new i9 8-core computer went quickly, mostly because I was starting with a new install of Ubuntu Jammy. Only a few of the steps were needed--the R 'devtools' download was simpler, though I still needed a GitHub access token. I created a Python virtual environment to avoid the system-wide corruption and bit rot that catches up with all of us--eventually.

Now I am down to replicating my ZK setup, to facilitate Zettelosophical investigations in bed, in case the journey out of bed to the Monastic Study Alcove, shown below, is too arduous.

Sascha · November 2023

@ZettelDistraction Almost perfect. I'd rotate the desk a couple of degrees to the right if it works with the light from the window. This gives you more space and better feng shui.

@Sascha: thanks. But for the furniture opposite, I would reposition the desk. Most of the junk on the shelves, which includes a couple of 900 MHz transceivers, sub-gigahertz antennas, old notes, certified mail return receipts, anatomy flashcards, Bluetooth headphones, a disposable razor, ancient cassette tapes, and patch cables could be discarded, except for the electronics and writing supplies, which go into storage--if there is any storage.
