    I don’t understand the “that’s no how PDFs work” criticism.

    Removing data from the original file is the whole point of the exercise! Of course unique tokens can be hidden in plain sight in images, letter spacing, etc. If we want to make sure to remove that we need to degrade the quality of the PDF so that this information is lost in said lossy conversion.

    It’s funny because the (far) left vilifies the police and then goes all surprised Pikachu when they turn out to not be manned by far left people.

    Idealism in all honor, but you’re not gonna change the system without being in control of the current power structures.




  • Interesting that there is a fine difference between humanitarian aid and humanitarian assistance. I doubt many journalist are this strict about their wording, but good to know nonetheless.

    Social welfare provides the exact same things (housing, food, medicine) but instead of some disaster zone somewhere it’s for disadvantaged citizens in your own country. Of course, the logistics are massively different, as well as the timeframe during which the services are provided. But it’s still basically the same thing: help other humans with fundamental necessities.

    So I would disagree with your claim that it “isn’t the same thing at all”. It differs in some details, but the central service and fundamental reasoning is the same.












  • Ich habe gelernt, das bei Lichtschutzfaktor 15 etwa 7 Prozent der Sonnenstrahlen an die Haut gelangen, bei 30 nur noch 3,5 Prozent und bei einem Lichtschutzfaktor von 60 wiederum nur noch die Hälfte. LSF 30 oder 50 macht in der Realität also keinen Unterschied mehr, das ist nur noch Marketing.

    Korrekt. Ander formuliert kann man auch sagen, dass Lichtschutzfaktor X bedeutet, dass jemand mit Sonnencreme X Mal so lange draußen sein muss um die gleiche Dosis UV Strahlung abzubekommen.
    Also 5 Minuten ohne Sonnencreme sind equivalent zu 5 Stunden mit Lichtschutzfaktor 60.
