  • One common misconception I've seen is people suddenly being afraid of their PTFE items they use at home. For example coated pans or PTFE cutting boards. They throw them out, because it thinks these will hurt them.

    However this is not true. The long chain molecules used in the final product are perfectly safe. They get all their useful features from being big molecules and being very inert. That's why they are used in the first place. As such these molecules can't interact with biologics at all. You can safely eat them, they will just pass through your body. They don't interact with anything and are too big to get incorporated into anything.

    The issue with stuff like PTFE is the production. That's where a lot of small PFAS molecules get used and after they've been used they can't easily be used again. So it's discarded as waste. But it turns out these smaller molecules can interact with biologics and not in a good way. And as they are still pretty inert, they don't break down at all. Hence the term forever chemicals.

    Back in the day Dupont studied if those smaller PFAS molecules they were discarding into the world's water by the boatload could do any harm. They quickly found out yes, it can do a lot of harm. But to not hurt the bottom line (number must go up), they kept it a secret. This has damaged the environment in a very significant way.

    When this came to light, they set out to design a new small molecule to use in the production. One that would be safe. So they did and used that, which satisfied the public for a time. However later it was proven this is a fantasy. The new molecule is just as bad as the previous one. And it turns out any variant of these kinds of molecules are just as harmful. That's why we now collectively call this class of molecule PFAS. Dupont probably knew about this, as the properties that made them useful in the production are the same properties that make it so dangerous to biologics. However since stuff like PTFE is too important in our modern world, we kept making the stuff. Only recently have we found out how big of a problem we are creating with that.

    So when you have PTFE or similar items, please keep using them. The damage for these items is already done and the end product is safe. It would be a waste to have done the damage and then not even use the end product. But when buying new stuff, be on alert. Try to find out if PFAS was used in the production of the item and try to avoid where possible. There has been talk of laws in the EU which would require the label on a product to show if PFAS was used, so people can avoid it. But we aren't there yet.

    If we were smart, we would ban it altogether. But like I said, too much of the modern world depends on these kinds of materials. So that's probably not going to happen.

  • If you want to go Intel, I'd say wait for the B700 series. The B500 series has proven a decent budget gaming card, but the 9060 XT is a solid midrange card and will be a lot faster than any B500 card.

  • I think my face scrub still has these. But I would have to check, it might be just sand they put in there. Works great tho.

    Edit - I checked, the ingredients say it's silica. So yes, they put sand into it.

  • It's good to see more and more vegan candy being sold. These days I've even come to expect it. When it isn't advertised on the packaging I check the ingredients and more often than not I see they are in fact vegan.

  • I think they meant people don't know how these models work in practice. On a theoretical level they are well understood. But in practice they behave in a chaotic way (chaotic in the math sense of the word). A small change in the input can lead to wild swings in the output. So when people want to change the way the models acts by changing the system prompt, it's basically impossible to say what change should be made to achieve the desired outcome. And often such a change doesn't even exist, only something that's close enough is possible. So they have to resort to trial and error, trying to tweak things like the system prompt and seeing what happens.

  • I humbly reserve the right to give you a hug, if you'd consent, for all you did for us. Also I would like your permission to kick you in the balls for this "announcement". If your biology doesn't allow for that, don't worry, I've got a magic spell that can give you balls just long enough for me to kick them.

    Just kidding, love you <3
