  • They often are partially recycled material. But recycled paper isn’t like recycling aluminum or steel. There are limits to how often and how much of the cycled material you can add back to make useful paper products.

    But paper towels can and does make great compost as most gardeners know. And a properly run landfill is a compost pile. But you need to keep the nasty garbage out.




  • Violence from the masses requires the masses to feel like they are starving, sick, and dying with no way out except death. We have been slowly accelerating towards that violence for a while now.

    Watch for an increase for those CEO’s, (at least insurance and pharmaceutical CEOs), to have much increased budget for private security measures. Both in surveillance and personnel. I think we will start to see more ‘black limo caravans’ like the the POTUS moves around in. And being surrounded by people in black suits with guns openly visible. They will do whatever it takes to stay alive and be evil.

    The next question is: how long before politicians start becoming targets?




  • I understand that the state has a monopoly on violence. Violence IS the ultimate power to rule no matter the form of government. What you don’t understand is you can’t limit that power. Once granted, even on what might appear to be a limited basis, and it’s never limited for long, cannot be revoked. You can totally remove the power of the government to use violence and then hand that power to the populace-- but this is not a good idea. The only thing dumber than the government is the public.

    The person I responded to stated plainly, they were for killing billionaires. They just didn’t want the government to do it. So he must be willing to pull the trigger himself. Which is a valid political stance. Even though I think it’s very misguided.

    You have read into a plain statement something YOU believe. And if you don’t understand that, then I don’t know what to tell you either.



  • There are a few studies starting to show up about FDM food safety. Very preliminary results seems to indicate it’s not as unsafe as everyone claims. After all, think about all those plastic cutting boards in daily use in commercial kitchens and homes across the world right now. How much bacteria gets hidden in all those cuts?

    But the upshot is that more comprehensive studies do need to be done to determine just how safe or unsafe FDM printed food items are. It’s still at the point of YMMV and proceed with caution as determined by your own risk tolerance.


  • PETG benefits a bit from drying. Though I don’t really get too excited unless I see stringing.

    Adjust your retractions. Look at your retraction settings. You might need a bit longer and faster retraction. Or you might not want any retraction at all. YMMV per machine and filament and print. I like the scarf joint over straight retractions.

    Wipe at the start and during a reaction.

    Lower your print speeds a bit. I find running a bit slower helps with quality.

    Lower your cooling fan speeds. PETG doesn’t play well in a hurricane. Even keeping it off completely has helped me on certain prints.

    Use temp towers to choose the best temp for minimal stringing.

    Notice I didn’t provide any numbers. That’s because every machine and the environment it works in is a rule unto itself. But your slicer will give you a baseline to start from. It’s up to you to figure out how to tune the settings you need to get the best results for your printer. There are no shortcuts here.

    If they did, they wouldn’t need engineers.

    But it’s more of a division of labor I think.

    It is the job of the scientist to discover a new idea. It is the job of an engineer to kill enough people to make the idea just safe enough to turn loose on the public.

    Remember kiddies, scientific principles are written in ink. Engineering principles are very often written in blood.



  • I’m not so sure. Children have a lot of desire and drive to monopolize an adult’s attention and resources. This I think gives any one child a leg up on getting the best resources to survive better. And you can see it when you work with a group of children. They will group around you jostling for the best position to be first and get the best from you. They do of course, get better with age and as they learn patience, but there is still a lack of empathy to be found in their base behavior.

    After all, if you grew up with siblings, I’m quite sure your parents at some point in your early childhood told you “Be nice to your siblings! You love them!” more than once. Or some variation on that theme. And if you are a parent yourself, you have used that phrase at some point also. Because who has better reason to want to “kill” each other than brothers and sisters? They want to get as much of mommy and daddy as possible. Those resources are scarce and your natural drive is to fight to get them.

    And hopefully, as children age they learn to get and show empathy to those around them. Most do, but some never quite manage it.



  • The short story is that all materials have internal stresses when made. Whether it’s lumber or steel or cast iron, they all have stress that need to be relieved before you can expect them to hold their shape. Some materials are worse than others. And anytime you cut or machine them, they can move in unexpected ways that can make your parts not fit together as required to make a working machine.

    A “green” iron casting has a LOT of internal stresses created by the rather violent process of making the casting. Even way back in the day, they understood the problems that those green castings had. And if you want your lathe to be stable enough to hold those tight tolerances to build a train steam engine or bore an accurate cannon barrel you needed to get as much of that stress out of those lathe bed and head-stock castings as possible before you carefully machine and scrape the ways on your lathe into perfection so that the casting becomes as stable as possible.

    The best method of relieving those stresses from your raw castings was to repeatedly heat and cool that casting. And the easiest and best way to achieve that was to literally store those castings outside for a few years to let them naturally heat and cool with the changing seasons. If you go on YouTube, you can find videos of British steam engine manufacturing from start to finish. And at some point you will see their outside yard filled with raw castings aging in the natural heat and cold of the changing seasons.

    We still age cast iron to today to make it stable enough to use. But we now use accelerated methods of stress relieving metals that are much faster, but more costly.

    He didn’t actually kill the intruder so that’s something he can probably look forward to either after joining the military or law enforcement.

    But joking aside, children by in large, don’t seem to have much empathy about such things. You can see this in the bullying they do in schools and on the playgrounds. And it doesn’t seem to bother them much.

    I got no proof other than my personal experiences growing up and observing kids while teaching them in groups at a school.

    Children by in large seem to have little empathy for others. Children have little to no problem with bullying others without any emotional issues. Even to the point of pushing other kids to suicide. They have little regard for others and even less control over maturity.

    I think empathy is something that you develop as you grow older. It’s more a mark of adulthood than childhood.
