    If you have root you could theoretically add Memtest86+ to the boot order. There’s tools that allow adding boot entries in EFI. You could probably place a Memtest86+ binary in your EFI partition and register it with the EFI firmware. But I’m not suggesting to do it since you could make the machine unbootable and the problem might be on the storage path. I’m just thinking of should be possible.




  • While true, I’m discussing the significance of exposure. That is what amount you can get into your body from different sources and the appropriate attention they should receive. PFAS in PTFE are residues from shit manufacturing. Even when they’re present, the amounts aren’t large. Stain-resistant furniture and carpets on the other hand are literally laced with PFAS to achieve this. So are most water resistant jackets. Household upholstery sprays like Scotchgard had PFOS as their active ingredient. Not sure what PFAS they use today. I know of multiple people who read a few titles about PFAS, replaced their cookware and kept laying naked on their PFAS-laden couches until I alerted them to it.

    E: Forgot about food packaging.




  • PFOA is a relatively larger compound, and smaller “short-chain” PFAS that industry now more commonly produces and claims are safer were absorbed at higher levels – up to nearly 60% of one short chain compound dose was absorbed by the skin.

    “This is important because we see a shift in industry towards chemicals with shorter chain lengths because these are believed to be less toxic – however the trade-off might be that we absorb more of them, so we need to know more about the risks involved,” said study co-author Stuart Harrad.

    Oh nice. Well at least shorter chain PFAS degrade faster, but that’s a shit consolation prize.


  • Non-stick cookware isn’t a significant source of PFAS exposure because while technically a PFAS, PTFE is a stable polymer. This is important because you might have replaced your cookware and feel safe while not realizing that the sofa and the rug in your home are spewing PFAS in the air every time you brush against them. I threw out a nice sofa because of this. Furniture and carpets are the main source for residential PFAS exposure. Unless your water is super contaminated of course.
