  • What are you even talking about? They’re curating the communities and instances they engage with. That’s literally one of the core functionalities of the fediverse.

    “YOU’RE NOT ENGAGING WITH LITERALLY WHATEVER IS PUT IN FRONT OF YOU. MAYBE YOU SHOULD STOP USING THE INTERNET!”

    Omg I’m dying lol 🤣

    Hey OP, I have a suggestion for someone to block… I’m going to block him as well.












  • A black venti coffee from Starbucks has almost 450mg of caffeine. 200mg probably isn’t “whopping (!)”-worthy.

    I have a co-worker that drinks a pot of coffee at work each day by himself. That’s about 1,200mg of caffeine, and he has a cup in the morning before he gets to work, so he’s probably having about 1,500mg/day. Admittedly that’s on the high side.

    800mg of caffeine from black coffee per day is actually shown to be good for you. Reduced risk of alzheimer’s, type 2 diabetes, certain cancers, and Parkinson’s. Reduces inflammation. Lowered rates of liver cirrhosis and liver cancer.


  • It’s more or less an inevitability at this point, regardless of what we do. Really we’re just trying to get corporations and countries to make changes so it will be Gen A’s (or the following generation’s) problem instead of Z.

    Normalcy now has an unavoidable term limit. The question is if we’re going to shorten how long that timespan is by desperately holding onto normalcy now for as long as we can, or if we’re going to start making things harder, more challenging, and less normal sooner to make the transition less painful and give it a longer on-ramp.

    Currently we seem to be choosing option A.

    For what it’s worth, I’ve seen some friends take things a little more seriously when I’ve explained that currently we’re going to see abrupt and incredibly disruptive changes at the point in our (Gen Z and Millenials) lives when we’re at the age when we’ll be least able to tolerate the changes and most reliant on others. In 40-50 years, Z and M are going to be senior citizens at best. While we may be full of distracted, dopamine-seeking denial now, by the time shit really starts hitting the fan, we’re going to be extra weight on the generations struggling desperately to survive.

    Don’t expect a happy retirement.








  • This study looks at how particles released from 3D printers (specifically using ABS and PLA filaments) can damage cells and potentially lead to cancer. They found changes in gene expression linked to cancer development, but they can’t definitively say 3D printing causes cancer yet.

    If you read the full study, though, it’s clear that exposure to these particles affects cells in ways that suggest further research is needed to figure out just how dangerous it is, not if it’s dangerous. The study avoids outright claiming that 3D printing causes cancer because it was mainly designed to assess cellular responses to particulate exposure, not long-term cancer outcomes.

    They did see cellular changes linked to cancer pathways, but the study’s design didn’t allow them to draw that direct conclusion. A follow-up study focused on these gene expression changes and long-term effects is likely to show a clearer link between 3D printing exposure and cancer development.

    That being said, this isn’t the only study. For instance, particles emitted during 3D printing—especially ultrafine nanoparticles—have been shown to cause cellular damage, oxidative stress, DNA breaks, and inflammation, all of which are early indicators for cancer development. In one study, exposure to ABS fumes led to a 49.5% decline in cell viability, pointing to high toxicity levels.

    Other research has suggested that people exposed to 3D printer emissions have a cancer risk 3.44 times higher than those exposed to typical urban pollution. To be blunt, it’s pretty well established that the particles emitted from 3D printing processes are biologically active and harmful. I think that most people engaged with the hobby probably know that intuitively, which seems borne out by the tenor of many of the comments here.

    It’s dangerous, and it’s likely shortening your lifespan in the long term. You might not care now, but if you get cancer in a decade or two, I imagine future you will feel differently. “Do you” and all that, but I’m amazed by the amount of people 3D printing without air filtration and vent hoods. The fact that some people do this in the open air in their living spaces is mind boggling to me.
