I'm celebrating Happy Fireworks Day!

I've got new neighbors that are probably about to hear, "Fire in the hole!" unironically for the first time. You can actually see the shockwave from my blackpowder signal cannon. Good chance the cops show up.

I usually use the cannon to vaporize 10oz of kerosene for a nice mushroom cloud of fire, but I'll have to see how it goes.

I'm a pyro.

Y'all wear safety glasses if having bottle rocket fights or roman candle duels.

Depends on the cat and the relationship you have with the cat.

Dominance is also shorthand for the threat/wariness and manipulation thing that is part of the cat nature. Cats have a quick and very reactive nervous system. If a dog is a sedan or a truck, a cat is a two seat sports car. Cats are also manipulative as fuck. They'd be quite sociopathic if they were human.

I love cats (and dogs).

Late response, busy few days.

It's still not loading for me. Getting a white screen with a stuck load bar. Haven't tried it on a computer, just android. Maybe just post it here?

I agree that most people think they're working off reality. I generally think I'm working off reality, but then if you think about how little we actually percieve, we have a very dim view of reality. Extend this to the universe and beyond, and all our knowledge is a tiny rounding error that vanishes into zero.

All that being said, this isn't really anything you can live by. At least I can't. Most metaphysics are so much shit on a prick and untestable. My favorite is the simulation hypothesis, and one day we'll all live happily ever after in the computer. Not that it any way applies to my daily life.

Gravity still works, the sun will rise tomorrow, and vaccines generally reduce your risk of catching diseaes. So, I proceed with my best understanding of reality as I experience it. I try to force myself to face facts and change my mind given evidence.

So, back to the original topic. Here's a theroy: holding power and wealth in modern society may not be strongly correlated with an accurate view of objective reality but is strongly correlated in strongly believing you have an accurate view of objective reality. It also helps if you're a motherfucker that's willing to grind the bones of babies under your boots to get what you want.

As far as human society goes and the mutability of things like gender, money; mostly social constructs related to culture that has just grown by chance.

I do think we can point to some things that are pretty foundational to human culture, might even be impossible to remove: We're omnivorous primates that evolved into small family/tribal groups of 50-100 individuals. We sexually reproduce through pairing by individuals that usually have a heterosexual preference. Those offspring benefit from at least the semi-monogamy of their parents. They benefit from their family/tribe which includes individuals that don't conform to the most common gender/sexual habits.

That being said, we don't have to conform to that. Society can be whatever we make it, maybe. Maybe not, I don't have a crystal ball, there may be limitations on how you can style society barring genetic modification or brain surgery or something.

Bless your heart. Go play quietly in your room, the adults are talking.

Have to get some shit done. I'll read through later and respond.

You're so close. So close. Brain in a box...

I'm not convinced you're not doing some sort of elaborate troll as you prove my point so well.

If it is a troll, you're a fucking master of your craft. You work so well against the things you claim to believe.

I get ERR_CONNECTION_RESET when I try to look at the site.

I don't know that I completely agree. Science suggests that there is an objective reality, it is our percepttion that is not objective.

Perception is reality, Plato's Cave and all that.

Humans are mostly driven by emotion and using logic to make decisions, even only at the personal level, is difficult and rare. Leaders, political and religious, use that emotional thinking to consistently short circuit logic and rationality. They drive emotional thinking in whichever direction to achieve their goals, usually at the expense of the people.

Personally, I've had 'good' results over the last few years deliberately divorcing emotion from the decision process and just looking at the facts as best I am able to understand. Watching everyone around us going nuts: friends and family into Qanon and MAGAtry, vaccine denial, etc. It's been painfully educational.

Best I can tell, most people are functionally illiterate and irrational. (Illiterate may not be the correct word, un-critical maybe?)

I now think that most people of the left are the same, maybe a little better. Tankies here on Lemmy are a great example, they're so emotional that their brains have fallen out. I fall firmly on the left even if I think that most of us aren't really thinking and are actually working off what feels correct.

So, while I do think there is objective reality, I don't think most people are even trying to work off it. I'm not sure that we can. So, functionally, reality is pretty subjective.

I do know that, personally, I'm driven to try and gain as accurate a worldview as possible given the facts and science available to me.

I have almost no mysticism left in me. I do feel awe at the natural world, the cosmos, my love for my people. I'm comfortable allowing that feeling guide some of my decisions. I don't think much personal harm will come from a deep respect of nature, for instance.

After losing my religion, I have defined my life's purpose as taking care of my people. It's arbitrary and emotional, but it brings me comfort.

Now, that's a different angle on viewing these things. Or at least I've never heard it phrased that way. Interesting. Thanks for the insight!

Even for a 12ga pump? Most people don't need a handgun. Scattergun will do most everything you need, from putting food on the table to handling two or four legged varmints.

Now, that's pretty funny.

Clearly this is a couple of straight guys, probably in the military, that are locked into a game of gay chicken.

Tightly, firmly, locked.

 

Trying to get a better understanding on the whole tankie thing, found this study that seems unbiased. It looks at their online behavior. I would appreciate others review of the study, even if just bullshit or facts.

Jeebus these people are exhausting, they also spray so much disinformation. They remind me of MAGAts.

I don't yet have a feel for the dynamics like I do with MAGAts. How much of it is organized with handlers and such vs. organic true believers?

 

Been getting slow loads and timeouts all morning. Figure it will probably resolve on its own. Didn't see any reports. Running Jerboa 0.0.77-gplay.

 

My son is about ready for his first printer. His school is running Cetus MK3 printers, he has a class using them, and his teacher has recommended this printer. He also has an educational seat of Fusion 360.

I'm proficient with Mastercam and hand written/modified G-code. I can help him with CAD no problem. Alignment, assembly, adjustment, and backlash are second nature for me. Have a little better than layman's understanding of printers. (Lusted over the Markforged printer that could do continuous carbon fiber.)

Eventually, will be building my own shop and hope my son might work with me. Hope to include printing, especially in metal.

I've seen some of the flap about Bambu and them closing up the software tool chain. I would like to avoid that sort of thing, for now, openness is better.

Top of my budget is around $500, with $200 probably being better.

Usable prints for tooling/spacers/repairs would be a bonus as would being able to print UV resistant plastic.

My goal for him is to get gud at modelling and get a feel for computer controlled movement. Another goal, harder to describe, is him finding the joy in mechanical tinkering and producing an idea made physical.

Thank you much! What do?

 

Any of y'all got a tracker that is following which portions of Project 2025 have actually been enacted? Something like the chump lawsuit tracking? Not finding anything with a search.

 

Does anyone know about Syrian Latakia tobacco?

It's a major component in English and Balkan style pipe tobacco. It has been replaced by the inferior Cyprian Latakia tobacco.

 

I have added a wifi repeater to the outside of my home so that my wife can watch her critter cams. It is a POE device that runs all the way back to my router.

Would like to install this surge protector but I'm getting conflicting information on grounding it. My installation is to the side of my house, not a metal pole.

Lowest effort options first, I can:

A. Place the protector inside near where the CAT5 enters the basement. Ground to a junction box that I installed that is grounded to the house panel and rod.

B. Ground internally to a water pipe or externally to the outdoor spigot.

C. Drive a ground rod where the cable exits the house and ground to it.

D. Repeat C and also bond to to the pre-existing home ground rod. (Least preferable option, rods would be on opposite corners of house.)

 

They hate each other so much.

 

Just looking up some DIY medical procedures and then the unwanted AI goes off the rails.

 
 

Found this broken piece in the creek bank. Southwest Pennsylvania. Farmhouse was built in 1922. Coalmining country.

Would have been about 18" in diameter. There is a rough coating in the glaze on the inside and outside of the bowl section. Abrasive enough that I figure it served a mechanical purpose. There are three grooves on the rim that aren't symmetrical to each other.

There might be a makers mark in the center of the glaze inside but I can't make it out. There is also a light blue/green stain on the bottom that might be a mark.

Any ideas?

 

Celeb_pics appears to be some bot posting from whoischic.com. Cluttters up /all.

 

The electric PTO clutch on my 1969 mini tractor is dead and discontinued.

Original winding is aluminum 18 gauge. Manufacturer specs were 2.88ohms, 237 turns. The manufacturer specs didn't quite physically match what I found when I took apart the old clutch. If I understand this correctly, the 2.88ohms is the most important part and will pull 4.17 amps.

I just attempted a coil with 18 gauge copper magnet wire. I made it to the max dimensions I can get in the housing with a scramble wind. I'm getting 1.2 ohms, which would pull 10 amps or so. Not good.

Was able to get 187 feet given the resistance.

If I go with 20 gauge copper, assuming I can get 235 feet (1.26 * 187) and I should get 2.319 ohms. Probably get a little more than 235 feet and get the resistance up a little more.

What does this do to the strength of the magnetic field?

Would I be better off putting a power resistor in series with my 18 gauge coil?

Any advice greatly appreciated!
