    leaded solder without an extractor fan

    • lead does not vaporize at the temps used in soldering.
    • lead free solder also needs fume extraction. even more so actually, because it is used at slightly higher temps.
    • even with perfect fume extraction, leaded solder can still poison you, because you touch it and then touch your face without washing your hands.
    • if you are prone to allergic reactions from solder fumes avoid solder with a rosin core, use synthetic flux instead.




  • Are we still talking about PNG? Nowhere in the PNG standard is a description of changing the actual content of an image to make it compress better with DEFLATE. If you are thinking about the filter stage you should know that in this context an image filter is just creating a different representation of the same image, because it is fully reversible.











  • senders can only be easily forged if you control the senders mail server or if they don’t use best practices for running a mail server.
    See also:

    there are cryptographic signatures on almost all mails sent by large mail providers these days, which makes it very hard to just forge an email that will hold up to closer examination with the help of the provider. so basically the IT techs of the company would need to be on board with whatever the perpetrator is doing, for them to get away with it.



  • Trying to remember what i learned in history here, i hope i get at least most of it right:

    • the political institutions of the Weimar republic were not as balanced and protected from interference as in other democracies
    • many parties were against the existence of the Weimar Republic
    • they differed a little in what they wanted instead though, ranging from reintroducing the monarchy with a few republican elements, to full fledged socialism
    • the difference between the parties made finding compromises very difficult and often resulted in stalemates in the legislative, because of missing checks this did not affect the executive as much though
    • especially the monarchists liked the idea of heaving a leader that can overrule the parliament if needed and so it was easy for Hitler to get them to agree that they would all be better off with him breaking the stalemate so to speak. So they formed a coalition
    • see also https://en.wikipedia.org/wiki/Harzburg_Front
    • Those parties also had no qualms with banning other parties just because they disagreed on something, which Hitler was very happy to do, starting with the communists and ending with a complete ban on forming political parties after every serious contender was eliminated
