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."

My organisation demands me to change my password every year. If I forget, they send a password reset code to my personal email address, OUTSIDE the organisation, an address that I did not remember ever sharing with my employer, an account I may share with family, or that I may not have used in a year, or for which my domain registration may have been canceled. #security

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. Pretty neat if you ask me

Herinnering aan iedereen behalve Dilan Yeşilgöz: Chef Special en Typhoon speelden tijdens het #RodeLijn protest in Den Haag voor 150 duizend mensen met een oproep aan de Nederlandse regering om te stoppen met de Nederlandse steun aan Israel's totale vernietiging van Gaza en de moord op Palestijnse burgers door Israel. Heel dapper, bedankt Joshua. #Gaza #GazaGenocide

Israeli newspaper Haaretz tells 28 stories behind the staggering death toll of children in Gaza, their faces, names, and dreams that will never be realized:
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

Another educated guess: Think about eating #vegetarian?
How many animals would you save in one year?
One way to determine this: Divide the number of animals killed by the number of people that eat meat.
Good news: Maria Salazar of Animal Charity Evaluators did just that.
Her conclusion? A vegetarian saves 105 vertebrates per year: 79 wild-caught fishes, 14 farmed fishes, 11.5 farmed birds and 0.5 farmed mammal.

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.

Search online for photos of Afghanistan in the 1970s, and decide for yourself: Did the cold war interventions of Russia and the USA do Afghanistan any good? (and NATO interventions -- even the Dutch invaded Afghanistan, I am ashamed to admit)

Many people online think that the USA switched sides, and now support Russia instead of Ukraine. I am more cynical. They were never on Ukraine's side. They're trying to create a failed state at Russia's borders: divided, in debt, without a properly functioning government. That's what they did to Afghanistan too (and Libya, Iraq, Sudan, Syria)

2025-03-01 08:51:43 UTC

There's an interesting analogy between Volodymyr Zelensky and Osama Bin Laden. Both received US military aid to fight wars against an illegal Russian (Soviet Union) invasion and both were betrayed and publicly humiliated by the US at the end of those wars... #ukraine #russia #us #afghanistan
