I have been interested in personal knowledge management (pkm) for a very long time. I have been an avid notes maker ever since I learned to write. Digital tools from the late 1980s onwards have been extremely useful. And a source of nerdy fascination, I confess. I am certain personal knowledge management (pkm) is of tremendous value for anyone who wants to keep learning and make sense of the world around them.

On March 22 and 23 the European PKM Summit is taking place in Utrecht, Netherlands. I have helped invite speakers and workshop hosts for this event. I am donating a ticket for a student in the Netherlands to attend this two day event.

Are you a student in the Netherlands with a strong interest in personal knowledge management (pkm)?
Is your interest in pkm to strengthen your personal learning and deepen your interests, rather than increasing (perceived) productivity?
Would you like to go to the PKM Summit on 22nd and 23 of March in Utrecht, but as a student can’t afford the 200 Euro ticket price?

Then I have one (1) conference ticket available! Let me know who you are and what fascinates you in pkm or attracts you to the event. If there are several people interested I will choose one. I will donate the ticket by March 8, so state your interest before then.

The single condition is that you attend the event on both days and participate actively. There is a session on the program that may be of interest, focused on pkm for students and teachers for learning and research contexts. It would be great if you would share some of your impressions of the event afterwards, especially if that is something you’d normally do anyway.

Interested? Email or DM me (in Dutch or English)!

On 22 and 23 March, roughly in a month, the first European personal knowledge management (pkm) summit will take place in Utrecht, the Netherlands.
Over two days a varied line-up of PKM practitioners will present, show and discuss how they shqpe their personal learning and information strategies.

Personal knowledge management is enjoying a wave of renewed attention due to a new group of note making tools that has emerged in the past few years (such Roam, Logseq, Obsidian, Notion et al). But personal knowledge management is way older. People generally notice things around them, and strive to make sense of the world they live in, wether on a highly practical level or a more abstract one. The urge behind PKM therefore is deeply human. The methods and availability of tools have changed over time, as has the perspective on what constitutes personal knowledge.

Over two days a long list of well known and less well known practitioners of personal knowledge management is lined up. I had the pleasure of finding and approaching people to participate as speaker or as workshop host. This includes experienced voices like Harold Jarche. Next to invited speakers and hosts, there will be ample time on the schedule to do your own impromptu session, unconference style. The program will be shaped and finalised in the coming week or so.

The event is organised by the Dutch community ‘Digital Fitness’, and a non-profit effort. There is space for at most 200 people, and there are still tickets available. Tickets are 200 Euro for the two day event. The venue is a short walk from Utrecht Central Station, at Seats2Meet.

I hope to see you there!

Bookmarked Jaarbeeld Ransomware 2023 (by NCSC)

De projectgroep Melissa, waarin diverse partijen zoals het Nationaal Cyber Security Centrum deelnemen, geeft een overzicht van hoe het met ransomware ging in 2023 in Nederland. Er wordt gekeken naar organisaties met meer dan 100 mensen.
Het beeld is dat van de kleine honderdvijftig bekende incidenten, de politie vaak wordt betrokken, slachtoffers met name in industrie en handel voorkomen, en daarbij in minder dan de helft van de gevallen een back-up voorhanden is. Niettemin wordt in minder dan een vijfde van de gevallen betaald (wereldwijd iets minder dan de helft). De gebruikte ransomware wordt ‘opvallend’ gevarieerd genoemd: 23 ‘families’ ransomware zijn zichtbaar.

Mij valt op het gebrek aan back-ups, die ik maar als reminder opvat om regelmatig te kijken hoe dat bij mij en bij mijn bedrijf daadwerkelijk is.
Veel handelingsadvies wordt er niet gekoppeld aan dit overzicht (anders dan ‘pas op!’) overigens. Dat roept een beetje de vraag op voor wie dit overzicht bedoeld is.

Dit jaarbeeld compileert informatie over ransomware-incidenten bij grotere organisaties, afkomstig van gespecialiseerde cybersecuritybedrijven.


On the Obsidian forum I came across an intriguing post by Andy Matuschak. Matthew Siu and Andy have made an Obsidian plugin to help with sensemaking and they are looking for people with use cases to test it out.
I filled out the survey saying I had a large variety of notes about EU data law, digital ethics, and (data) governance, which I need to make sense of to guide public sector entities. They asked about online traces of me as well. Soon Matthew reached out and we decided on a time for a call.

And that is how I ended up working in Obsidian for an hour while Matthew and Andy were watching my shared screen. Sort-of how I once watched Andy work through his notes after reading a book. They’re on the US west coast, so with the nine hour time difference it was 22:00-23:00 hours here, which plus my cold meant I wasn’t as focused as earlier in the day. It also feels slightly odd to me having people watch me while doing actual work.

Because that was what I did, doing some actual work. Using notes from several conversations earlier this week, plus EU legal texts and EU work plans, and notes from workshop output from over a year ago, I was working towards the right scope of a workshop to be held early March.

The plugin I tried out is called the Obsidian reference plugin.
It allows you to select something in one note, and paste it in another. It links back to the source, is uneditable where you paste it, and marked where you copied it. When you hover over it, it can preview the snippet in its original context, when you click it the source opens/focuses in another tab. It seems a simple thing, and similar to block transclusion/references, yet still it had some interesting effects:

  • Initially I saw myself using it to cut and paste some things from different notes together in a new note. This is a bit like canvassing, but then solely in text, and focused on snippets rather than full notes.
  • The snippets you paste aren’t editable, and the idea is you can paraphrase them, rather than use them as-is like in block transclusion. I did a bit of that paraphrasing, but not a lot, it was more like gathering material only. Perhaps as I was bringing together parts of my own (conversation) notes. I can see that when going through the annotations of a source text, this can be a second step, thinking highlights and annotations through, remixing them, and come up with some notions to keep (see second to last bullet).
  • It was easy to bring in material from a range of notes, without it becoming hard to keep an overview of what came from where. This is I think key when comparing different inputs and existing own notes.
  • Once I was interacting with the collected material, my use of additional snippets from other notes shifted: I started to use them inline, as part of a sentence I was writing. This resembles how I currently use titles of my main notions, they’re sentences too that can be used inside another sentence, as a reference inside a flowing text rather than listed at the end. I often do this because it marks the exact spot where I think two notions link. This means using smaller snippets (part of a phrase), and it is possible because the reference to the source is kept, and its context immediately accessible through hovering over it.
  • Discussing this effect with Matthew and Andy I realised another use case for this plug-in is working with the content of the core of my conceptual notes (that I call Notions) inside project or work notes. Now that reference is only to Notions as a whole. Adding a snippet makes a qualitative difference I want to explore.
  • You can collapse the snippets you create, but I didn’t do that during the hour I let Matthew and Andy watch me work. I can imagine doing that if I’m working through a range of snippets to paraphrase or use. I can see this being useful when for instance collating results from in-depth interviews. For my World Bank data readiness assessments the report was based on snippets from some 70 (group) interviews. A lot of material that I would mine along the lines of ‘what was said about X across all these conversations’, or ‘what assumptions are voiced in these interviews regarding Y’.
  • I spent the hour working with notes mainly from conversations, which are often pseudo-verbatim with my associations and questions I had during the conversation mixed in. Reading old notes often allows me to be ‘transported’ back into the conversation, its setting etc in my memory. Being able to glance at a snippet’s context from conversation notes as I work with it, and getting transported back into a conversation, felt like a rich layer of potential meaning being made easily available.
  • What I created in the hour was something I otherwise likely wouldn’t have. I was able to build or at least start a line of detailed argumentation for both the scope of the workshop in March I was working on this hour, as well as a line of argumentation to be used within that workshop to show participants why taking EU developments into account is key when working on a regional or local issue with data. In a more explicit way and I think I might otherwise have come up with a ‘result’ rather than the path to that result. ‘Thinking on paper’ in short. Useful stuff.
  • Reflecting on all this afterwards before falling asleep, I realised that a key way to use this is connected to the video I linked to above in which Andy gathers his thoughts and notes after reading a book: reflecting on an article or book I just read. A key part of the work there is seeking out the friction with previous reading and Notions. Not just to work with the annotations from a book as-is, but also the messy juxtaposition and integration with earlier notes. Then bringing in snippets from here and there, paraphrasing them into some sort of synthesis (at least one in my mind) is valuable. Collapsing of snippets also plays a role here, as you work through multiple annotations and ‘confrontations’ in parallel, to temporarily remove them from consideration, or as a mark of them having been used ‘up’.
  • Once you delete a snippet, the marking at its source is also removed, so if a link to source is important enough to keep you need to do that purposefully, just as before.

Bookmarked Coding on Copilot: 2023 Data Suggests Downward Pressure on Code Quality by William Harding and Matthew Kloster

Gitclear takes a look at how the use of Copilot is impact coding projects on GitHub. They signal several trends that impact the overall code quality negatively. Churn is increasing (though by the looks of it, that trend started earlier), meaning the amount of code very quickly being corrected or discarded is rising. And more code is being added to projects, rather than updated or (re)moved, indicating a trend towards bloat (my words). The latter is mentioned in the report I downloaded as worsening the asymmetry between writing/generating code and time needed for reading/reviewing it. This increases downward quality pressure on repositories. I use GitHub Copilot myself, and like Github itself reports it helps me generate code much faster. My use case however is personal tools, not a professional coding practice. Given my relatively unskilled starting point CoPilot makes a big difference between not having and having such personal tools. In a professional setting more code however does not equate better code. The report upon first skim highlights where benefits of Copilot clash with desired qualities of code production, quality and team work in professional settings.
Via Karl Voit

To investigate, GitClear collected 153 million changed lines of code,
authored between January 2020 and December 2023….. We find disconcerting trends for maintainability. Code churn — the
percentage of lines that are reverted or updated less than two weeks after
being authored — is projected to double in 2024 compared to its 2021,
pre-AI baseline. We further find that the percentage of “added code” and
“copy/pasted code” is increasing in proportion to “updated,” “deleted,” and
“moved” code.

Bookmarked A quick survey of academics, teachers, and researchers blogging about note taking practices and zettelkasten-based methods by Chris Aldrich

Chris Aldrich provides a nice who’s who around studying note taking practices. There are some names in here that I will add to my feeds. Also will need to go through the reading list, with an eye on practices that may fit with my way of working. Perhaps one or two names are relevant for the upcoming PKM summit in March too.

Chris actively collects historical examples of people using index card systems or other note taking practices for their personal learning and writing. Such as his recent find of Martin Luther King’s index of notes. If you’re interested in this, his Hypothes.is profile is a good place to follow for more examples and finds.

I thought I’d put together a quick list focusing on academic use-cases from my own notes
