Well, this particular user's account was not viewable on either Blacksky or Bluesky after moderation, even though they moved over to Blacksky before: "Bluesky claims to want decentralization and composable moderation, but they still enjoy abusing the power of arbitrary banishment."

I should've called them "instances" maybe. Only a PDS gives you exactly nothing: no instance of a social network independent of bsky. If Eurosky has no relay and no appview, then only blacksky is an independent instance, and even blacksky is dependent on bsky’s application server to give users a fast experience, which also means that it is dependent on bsky’s labeling system and its moderation choices. https://plus.flux.community/p/banning-controversy-reveals-blueskys

Everyone: Mastodon has thousands of servers. BlueSky has three servers (two-and-a-half, considering Eurosky does not run yet).
PublicSpaces: Let's invite all three for Bsky and one for Mastodon.

To conclude, I feel ashamed by the "AI and sustainability" strategy of the university, I cannot support it. The consultants that wrote the strategy missed two red flags. 🚩1 Some of our most talented professors object! A university strategy should be based on consensus. If your strategy is a comprise, forget it! 🚩2 AI is a horrendously unsustainable technology taking all the surplus electricity we have. You simply cannot have both AI and sustainability: Make up your mind, Radboud University!

And then there's the elephant in the room: AI of the chatbot and generative kind needs large amounts of energy. Letting a chatbot check the grammar and spelling of your text costs a million times more energy than the old Word grammar check (I am generous here, likely hundreds of million times). It's a completely UNSUSTAINABLE technology. Data centers are being built everywhere that strain the electricity grid and use water for cooling. AI is a big threat to the energy transition.

Some of our most talented researchers in AI, linguistics and computer science (they're on the Fediverse if you need them) oppose the AI hype. The board and the consultants who wrote the strategy may have listened to these researchers and claim the strategy is a compromise, that it promotes only "value-driven" AI, that we "consciously choose", etc. However, any strategy that is a compromise is a failed strategy. A common strategy must have consensus. Is there consensus? Clearly not.

Let me stress, AI as a discipline is important. I consider myself an AI researcher. I wrote my PhD thesis about language models. Some of my colleagues pragmatically embrace the new strategy (more money for us!). Not me, I'm ashamed. Is AI research more important than cancer research? more important that particle physics? more important than language studies? A university board should never even be tempted to make those decisions. Strategic decisions should be made by us, from the ground up.

This narrative, "AI changes everything", is problematic. It's the narrative put forward by OpenAI, Anthropic, Microsoft, Facebook, Amazon, Google, and let's be clear why: If you invest trillions in new technology without any clear return, of course, you would have to claim that it changes everything. In reality however, more than a trillion Euro is invested in autonomous agentic chatbots that are correct slightly more often, and that do no longer persuade people to commit suicide.

That changed! Our key value sustainability is now "sustainability and AI". The strategy repeats the narrative from Big Tech. AI is "developing rapidly and penetrating more and more areas of society and science", "AI directly impacts our region and society", and AI "can help us make our processes more efficient and enhance the quality of our services". https://www.ru.nl/en/about-us/mission-and-strategy/strategy-and-ambitions/sustainability-and-ai

Here's some of my thoughts on the new Radboud "Strategy & Ambitions". A university's strategy MUST be determined by, and widely supported by, students, professors and other employees. Our key value used to be "sustainability": You have a part to play! Sure, advertisement bureaus were paid, cringe movies were filmed, social media campaigns were launched, but at least sustainability was something we all can support. https://www.ru.nl/en/you-have-a-part-to-play

The mission of your generation is to destroy AI, kill it.
Whatever your chosen profession is, please don’t let AI rob you of the fun part of it. Our generation’s upcoming battle…is going to be people with substance versus people with shallow knowledge, it’s going to be mastery versus faking it, it’s going to be people with good taste versus tacky. I trust you will put in the work necessary to be on the right side of those battles

As I grow older, I more clearly see how science is never truly objective; That all scientific studies have political implications.
To my horror, I am starting to realize that some of the things I learnt and taught, such as significance testing, are rooted in vile, violent racism. Please, read Aubrey Clayton's "How Eugenics Shaped Statistics: Exposing the damned lies of three science pioneers."

Call on ABP: break ties with BlackRock: Sign the petition!
Why? Because #BlackRock keeps investing money in fossil-based industries. #ABP is one of the largest pension funds of the Netherlands. It organises pensions for academics like me. I don't want my money to support Blackrock. I don't want my pension to evaporate when Blackrock starts depreciating their investments.

My Fairphone 3 with e/OS does not even have speech to text(!) It does block trackers that are inside Android apps; allows you to use a fake location; you can hide your IP address using the tor network, and if you insist on using cloud storage it seamlessly intgrates with nextcloud.

Hind pleaded for help for hours. Youssef was killed while watching cartoons. Yaqeen wanted to be a YouTube star and died in a bombing. In death, Maria joined her mother and brothers, killed in an airstrike in 2021. #Genocide #GazaGenocide

Israel likely murdered 377,000 people in Gaza, A report prepared by Garb Yaakov, a professor at Ben-Gurion University of the Negev in Israel, and published on Harvard Dataverse website shows that the officially reported death tolls in Gaza are way too low. Half of the 377,000 that "disappeared" are children.

Excellent reasons for not putting all research software in #Github in this post by Luisa Orozco, Daniela Gawehns and Carlos Martinez-Ortiz
1. Github excludes potential collaborators. It is inaccessible to users in countries under financial sanction by the USA. (Iran, Syria, Cuba, North Korea, etc.)
2. Everything on Github creates a single point of failure. It has the possibility of being closed down, similar to what happened to Google Code.
Instead ilnk any git repo!
