This is the most fascinating video I've ever seen:

"“I think the fragility of life also really shines through in this video because this embryo is just exposed to the world and all of the things we do to the world.”

Website filmmaker Jan van IJken:

I'm new to Ycombinator / Hacker news. But the discussions seem interesting, so maybe I can check it more often.

This article is about 'infosec-handbook' leaving the fediverse. It sounds relatable, so I replied with this

I do also see the 'us vs them' on the fediverse sometimes. I think bringing together polarised people is a good thing. It should reconnect.

"If we’re to live up to our own time, then victory won’t lie in the blade, but in all the bridges we’ve made."

Currently in a guest lecture by Ruben Verborgh on the SOLID project (Social Linked Data), led by Tim Berners Lee:

Do you know it? It looks similar to the small-web initiative by @aral
( or the QiY scheme ( It definitely also has similarities to the fediverse.

Going to look into it, but curious to hear your thoughts!

Wow! Germany has had over 50% of its energy powered by renewable sources for the first time in 2021!

"Wind (27%), solar (10,4%), biomass (9,3%) and hydropower (3,7%) add up to 50,4%. Over 2019 this was still 45,9%. In 2010 it was 19,1%."

Practical advice:
1) Remember that often, we don't see the whole picture, and thus, conclusions might be biased.

2) Learning from 'successful' people might not be the best idea. Learn from everyone :)

Survivorship bias explained:




Cool! An insight in the source code of the BioNTech/Pfizer SARS-CoV-2-vaccin:

With translations in multiple languages!

Through Covid19, the young generation is asked for solidarity with the older generation.

Similarly, regarding the climate crisis, the older generation is asked for solidarity with the young generation.

To make sure you don't die, we stop meeting friends, having parties and do what young people normally do.

Please take the climate crisis seriously, consider to fly less, buy less and reduce your meat consumption. Thanks in advance! :-)

(idea from Werner Schouten in NRC)

It seems Bill Gates is also going for his Upgraded Worldview certificate. Wise man ;-)

Ancient mastodon pictures discovered in the Amazon rainforest!

"Their date is based partly on their depictions of now-extinct ice age animals, such as the mastodon, a prehistoric relative of the elephant that hasn’t roamed South America for at least 12,000 years. There are also images of the palaeolama, an extinct camelid, as well as giant sloths and ice age horses."


This makes me think of one of my favourite book series, Earth's Children by Jean M. Auel :)

Just came across this beautiful data visualisation of the top2000, check the website for the interactive version:

How much do you know about the world?

A great new tool from Gapminder, at

I must admit I had about 4-5 questions wrong the first time I tried 😇

Have you never heard of Gapminder? Then you might want to start with late Hans Roslings classic TED-talk:

Did you like it? Then I can recommend buying the book 'Factfullness' by Hans, Anna and Ola Rosling!(

What are your favourite songs? Please share =)

In the Netherlands, there is one radio station (NPO radio 2) that always plays the top2000 in the last week of the year, the top 2000 songs on which people voted. I love it, so that's the only part of the year where I move away from Pinguinradio and Spotify.

These are my votes for this year!

The Spotify playlist:

ScienceGuide: "Nederland heeft meer technici nodig en de academische wereld houdt dit nu tegen. Dat was één van de conclusies bij de hoorzitting in de Kamer over het nieuwe investeringsfonds."

Een enorm belangrijk onderwerp, en een boeiend artikel over deze hoorzitting. Dit klinkt als een mooie zitting om terug te kijken! Eens even 3,5 uur tijd zoeken komende weken. Voor de geïnteresseerde, hij is hier te vinden:

Ook de position papers zijn interessant:

Re-reading the great book 'The internet is broken - But we can repair it' that I received from Marleen Stikker after I won the privacy quiz at the Big Brother Awards show by Bits of Freedom (no luck involved at all :). That same evening, Marleen received the Felipe Rodríguez privacy award for fighting for internet freedom and privacy.

I'm looking forward to her lecture in the Week of Inspiration at the University of Twente:
