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.


Swiss author and playwright, picked the book up in Zurich in 2024. I thoroughly enjoyed Die Erfindung des Ungehorsams (2021), the invention of disobedience, and read it in one sitting. Well told, many beautiful sentences. Three women in NYC, China and England are followed as they try to understand the world. Their stories are interwoven through the emergence of AI driven automatons grasping their true autonomy. One because she sees the future in Babbage’s machinery and determines how to program them, one making sex dolls in China that get fitted with AI, one hosting Manhattan dinner parties where she tells, invents?, a story and only the others eat. All three finding a way to break their constraints, and become disobedient to their surroundings. A multilayered work, as one critic Daniela Janser wrote, a poetic homage to the oldest programming language of all, imagination. I will probably buy her more recent work Vor aller Augen, before all eyes, soon.

Teenage boy lost connection to his world and starts blogging as a school project, or rather journal writing because he never publishes a thing. The reader spends 142 pages inside the teenagers journal and head. This being a teenager’s head there’s no narrative arc really, just teenage slang, angst and endless second-guessing of themself and others. This novella (billed as a novel) was originally published in 2017, I read the 2024 pocket version. I picked this book in German up in a Zürich book store this week from the Swiss literature section, where it was hailed as a recent ‘classic’. It was ok, mostly because it was short anyway, but not recommended. Had it been longer I probably would have left it unfinished. The reason it gained attention in Switzerland seems to be its use of teenage and informal language as an apparant novelty. I think in other languages that sort of thing is decades old, no?

Part one of the Bridge trilogy. I bought it because I wanted to read Idoru, the 2nd part, because of a reference in a talk to ‘nodal points’ as coming from that book. Virtual light is triggering your optical nerve and brain with visuals directly without photons. The Bridge is the Golden Gate, since encrusted with people’s habitats. Gibson uses the word Thomasson to describe it. The US has splintered. In this setting a bike courier steals an object from what turns out to also be a courier, who is killed for losing it. A rentacop is brought in to find the bike courier but follows his conscience. A Japanese anthropologist who is on the bridge to observe (and hunt Thomassons), and references to a big earth quake in Tokyo which got rebuild by nanotech form the bridge to part two.
