  • Like evasive chimpanzee said we need to poop INDIRECTLY in crops. Hot aerobic composting for example has excellent nutrient retention rates and eliminates nearly all human borne diseases. The main problem would be medication since some types tend to survive.

    Also urine contains almost all of the water soluble nutrients that we expel and is sanitised with 6-12 months of anaerobic storage. So that’s potentially an easier solution if we can seclude the waste stream. Again the main issue would be medications.

    I don’t have the answer, if it was easy we would have done it already. The main issue is we don’t have a lot of people working on the answer because we’re still in the stage of getting everyone in the world access to sanitation. Certainly the way we’re doing it is very energy and resources intensive, unsustainable in the living term, and incredibly damaging to the environment. We’ve broken a fundamental aspect of the nutrient cycle and we’re paying dearly for it.

    The other problem is, like recycling, there isn’t a lot of money in the solution, so it’s hard to move forward in a capitalist system until shit really hits the fan.


    1. We mine and manufacture nutrient dense fertilizer at massive environmental cost.
    2. We use the nutrients to grow plants
    3. We eat the nutrients in our food
    4. We expel 95% of these nutrients in our waste
    5. We dump our waste into the rivers and oceans with all the nutrients (often we purposefully destroy the nitrogen in the waste since it causes so much damage to rivers and oceans)
    6. We need new nutrients to grow plants

    Before humans there was a nutrient cycle. Now it’s just a pipe from mining to the ocean that passes through us. The ecological cost of this is immeasurable, but we don’t notice because fertilizer helps us feed starving people and waste management is important to avoid disease.

    We need to close the loop again!



  • Hating the rich is like hating murderers, it’s not a feeling you should hide in polite company like racism. Every minute of their breathing lives they choose to take more from society than they give back. That’s how these dragons of modern times create their unimaginable hoards. No knight in stories of old hid their desire to slay the foul beasts, because doing so is always virtuous and worthy of praise.


  • Oh my god, it’s even worse when you zoom out. We’ll never catch up to the trend lines set by the years of unsustainable growth before the recessions in the 70’s. Oh the permanent damage we caused. It’s an absolute tragedy that after a recession we never get back to the trend line that was set by the bubble before it burst. I’m not patient enough for the slow and steady fundamental growth of humanity through time, I want continuous fast exponential growth so the shareholders can he happy all the time!



  • Usually in North America bidet refers to a modified insert or toilet seat that includes a sprayer and a lever to control. It doesn’t take up any space at all. Definitely a stand alone bidet takes up a lot of space but they’re visually non existent in North America, although I certainly would prefer that to the sprayers.


  • It’s never throwing your ballot in the garbage though. I used to think the same way, but every vote on the left, even if for the lesser evil, even if they lose, moves the conversation to the left. When we all stay home you get maga nutjobs stealing the show running unchecked.

    Last thing is that gerrymandered states are the EASIEST to upset by increasing voter turnout. To gerrymander effectively you have to put your opponent in dense areas they’ll win by a large margin, then spread your side so that you barely win the rest of the districts. That means that a 5% increase in votes on the left can take you from a loss to a nearly complete victory in a gerrymandered state.

    Vote splitting on the other hand is a trickier beast, but in the end if all the left votes go to a moderate then that gives the left a lot of leverage because if the moderate candidate doesn’t bend to the left then they’ll lose the next election.

    Always vote.


  • I don’t think the sentence you have is entirely accurate.

    High cost servo systems (motor, encoder, and driver) are superior to high cost strippers for dynamic positioning. Even that can be tenuous for low torque low speed applications, or nanoscale applications, etc… Certainly for 3 axis table/gantry CNC systems (router, laser, 3d print) for commercial/industrial grade applications servos are superior.

    If you’re aiming for a hobbyist price point steppers have better dynamic positioning performance than servos. You can build a $300-$1000 3d printer with servos, but especially at the low end, it’s not going to be good.


  • Lol the place that must not be named.

    It’s a numbers game. Getting engagement and knowing your audience are skills. The fediverse is a small place compared to meta. Being a big player in the fediverse for most posters is like being in the best team in a college league. Meta joining with 500-2000x the users is like suddenly having to compete at a national professional level. Certainly a few players have the skill, but most will get benched in no time.

    Maybe I’m wrong and I hope that I am, but I certainly know most default sub comments at the other place had no upvotes, no replies, and were at the bottom of the thread never to be seen. On here, nearly every comment i see or post has SOME engagement (like this discussion!). It’s a different game when you have hundreds of millions to billions of users.


  • You wouldn’t create a meta account. But I know I consume a lot more content than I create. Probably 1% of social media users create 80% of the content. If meta joined, the users that make most fediverse content now will see their engagement drop. There will likely not be a good reason for them to post at all since, in all likelihood, that content has already been posted by a meta user or reposted with more engagement.

    Eventually they’ll stop posting because it won’t be fun. At this point almost all content will be meta content, and most activity pub clients will be “alternative meta clients” in practice. If/When meta leaves, the fediverse will likely have a fraction of the content it has now, it’ll be a ghost town and have a long and hard road to recovery.

    That’s not to mention the other problems in the article.


  • When a big corporation like Walmart moves into a neighborhood it kills the small stores because it delivers most of what people want more effectively. Then when Walmart closes shops to consolidate those neighborhoods don’t go back to the way they were, they now have no stores.

    There is a lot of content in the fediverse that wouldn’t exist with meta, because meta users would provide better content, more discussion, and more votes would mean more granularity so better content rises higher. That would stop a lot of the people who post content on activity pub. They would be too late and have too little engagement to be relevant. Those people don’t magically reappear if meta decides that activity pub was just a bad mistake.


  • I don’t see any large leaps.

    If threads uses activity pub, most activity pub users will be meta users using the meta client. Meta will not feel the pressure to conform to the activity pub implementation. They could add features as they want since all their users will use their client. This will cause a sudden incompatibility and the fediverse will have to be the one to fix the problem.

    If the fediverse wants to update the protocol to add a feature, we’d have to run it by meta first since they would have to update their client. If they drag their feet it would be hard to force the update knowing it will disconnect the majority of users from the fediverse.

    It’s the same situation described in the article with Google and XMPP.

    I don’t see any leaps or jumps. This could be how meta kills the fediverse and we’d be walking into it eyes wide open.

    I think an ideal game starts easy then ramps up the difficultly. At this point you gain abilities that make the game easier and make you feel more powerful. Then the difficulty increases again at the end for the final challenge portion, that way you as a player feel like your have to master your new found abilities.

    Like going over a big hill then when you get to the valley on the other side you have to climb a mountain.






  • If you only had access to the coal furnace you couldn’t make power. The coal furnace is hot and it’s surrounded by room temperature air. The furnace really wants to heat the air around it and the air wants to cool the furnace because nature generally doesn’t like large differentials. So what we do is we force that heat to turn an engine before it can get to the cool ambient air.

    It’s like a putting a turbine in the way of a waterfall. The water wants to fall, so we force it to turn an engine before it can get to the ground.

    So back to your initial question, an AC is a heat pump. It pumps heat from the cooler inside to the warmer outside. It’s just like if we pumped the the water from the bottom of the waterfall to the top. Yes you can than use that water to generate energy, but you’re the one who pumped it up there in the first place so it’s a bit counterproductive.
