Aluminum oxide. Pretty damn inert.

By extremely poor, I'm talking physically disabled/mentally unwell/severely addicted. My viewpoint is from a rural southern us perspective. You see someone walking or biking, the assumption is that there is something very wrong with them and that they are probably homeless or nearly so. The only time you don't assume that with bicyclists, is if they're wearing spandex on a touring bike or are a kid.

I'm a total redneck so I've had plenty of friends and acquaintances that dealt. One former friend, only man I've ever called brother, I rode shotgun for a few times when he was making big moves. (he fell down the rabbithole with conspiracy stuff, we don't really talk anymore, the brother I loved is gone)

I'm still adjusting to seeing so many people walking in my new home. Other than gas station/general stores, I'm used to stores being 30mi/48km away.

Anyhow, anybody moving product had to have a vehicle as a basic part of their trade. Like a shitbox civic and a Hipoint 9mm were a part of the starter kit or something.

You can get fresh fish, but, you usually pay a premium. Fresh farmed catfish and tilapia are common. Now that I think about it, that's a type of factory farming I'm actually pretty okay with. As far as I know, their suffering is minimal and the environmental impact can be minimal or even positive when they are used to clean wastewater or fed byproducts. But most freshwater fish simply cannot be purchased, you have to catch them due to the laws. I now live within 300mi/482km of the coast, which is close by my definitions.

So buffalo vs bison is a funny thing. The american buffalo and bison are the same animal. However, buffalo refers to the wild ones and bison is farmed. Market hunters gunned them all down on the plains and that extirpation largely led to regulated hunting. Rinella drew a tag for one of the last populations of actual wild buffalo up in Alaska. (This stuff is closely regulated and actually backed by population science, one of the areas of law I actially agree with) So, he had to hike up a partially frozen river and stalk a buffalo, process it, and then pack and raft it out. He did this solo. He wrote the book while he was living in Manhattan, IIRC.

What about invasive vs naturalized?

[–] Machinist@lemmy.world 2 points 21 hours ago

Yeah. I bet we're going to find that it increases dementia rates by a lot.

I wonder what the effects are on brain development as well. I could see it doing something similar to children raised in warzones, fucking up adrenals and stress responses.

Right there with you on small trucks, the kid and I have been drooling over the Slate even if it is Bezos. I drive a '98 Ranger, and we've been kicking around the idea of a Ranger electric conversion.

Got me. Totally made that assumption. I now live within an hour of downtown of a large metropolitan area, there's even bus service here. However, even here, life without a vehicle would be full of hardship.

I'm used to only the extremely poor not having a vehicle. I don't know the percentage, but a large chunk of our homeless live in their vehicle and have jobs. Which sounds like pure hell.

Another assumption I made is game not being available unless you hunt it yourself. I've read about butchers in Europe selling game but I have no experience with it. The only wild meat you can purchase in a store is saltwater fish, pretty much everything else must be farmed. I understand, and agree, with the original intent. Market hunting was a terrible thing, effectively wiped out the buffalo for instance. It now needs to be brought back, and closely managed, for whitetail deer.

American Buffalo: In Search of a Lost Icon by Steven Rinella is a fascinating book. Rinella is one of the few modern hunters that I respect. He also has a show, MeatEater, that's pretty great. He's a thinking man's hunter.

That sucks. My wife and I saved and scrimped for years, and put a big chunk of retirement savings into it. We also moved 700mi/1100km buying the place without visiting it to make it happen. Huge leap into the unknown and we got very lucky to make it happen. We realized we needed to get out of the deep south in 2020. Couldn't afford to leave the country.

Small game should be totally doable for you if you're allowed to own a shotgun or . 22. (I love squirrel hunting, I harvest deer because we all love venison but find hunting them missrable and boring.) You could even process deer in apartment without your neighbors knowing. Gut in the field. Quarter or at least bisect them at your vehicle. Put parts wrapped in plastic in duffle bags. Carry into apartment. Further processing like skinning/deboning in bathtub/shower. Use cheap coolers with ice to do what is called wet aging the meat(common in the Southern US as it often isn't cool enough to hang).

Jesus fuck. I wasn't there, but your father abused you, displayed laziness, cowardice, and tortured animals. I find the cowardice of having you do it and then drowning particularly disgusting. Fucking yeller coward. I'm sorry you went through that.

I dispatch groundhogs in the trap with a . 22 revolver to the head using high velocity hollow points. I also know what the fuck I'm doing. They don't feel it. I've put down cats before, but I use buckshot to make sure, they move fast and fucking up with a pet is unacceptable.

My son could, and would, put down pets if I told him to or I wasn't able. It would fuck him up and it would have to be dire circumstances for it to ever happen. I'd have to be in the hospital or something and my wife would do it before he had to. That shit ain't right.

Start with fishing, easy to learn to clean from youtube and the emotional impact is a lot less.

You know what they say about camping sex? It's fucking in tents.

Seriously tho, fucking outdoors is the best. Hammock camping and fucking is awesome, hammocks are basically a sex swing without having to tote all the hardware.

My ethical views of livestock/game animals, factory farming, slaughter/hunting are pretty much identical to yours. From the Southern US.

Worked on farms as a kid. Chicken houses are a nightmare. The suffering inherent in industrialized meat production is hard to overstate.

I'm rebuilding our little farm. We're going to have steers, chickens, rabbits. Deer are very overpopulated and I'm going to be taking does to fill our freezer. Trophy hunters are disgusting. (Full disclosure, I've taken one trophy, will likely be the only one I ever take, she wouldn't have made it through the winter.)

Ethically, I think that if you're going to eat meat, you should have to kill and butcher an animal at least once. We'd have a lot more vegans that way. Factory farming should be abolished.

[–] Machinist@lemmy.world 3 points 1 day ago

I completely agree. Making statistics lie is a dark art.

The fascist fuckheads and their followers are doing so much blatantly evil shit that there is no need to embellish anything. The plain facts are plenty apalling all by themselves.

[–] Machinist@lemmy.world 1 points 1 day ago (2 children)

Cats are absolute hell on wildlife, especially ground nesting birds, and should be removed from outdoors. That being said, that's completely fucked up that it was put on you by your father. It also sounds like you had to use a pellet/bb gun, the wrong tool. Also sounds like you might not have had much experience killing animals, completely understandable, cute housecats is a terrible place to start with that and is fucked up. He shouldn't have done that to you.

I had a similar experience when I was 15 and working my first job, on a farm. Had to shoot a puppy. Guess my boss thought it would make me tough or something. I managed not to throw up or cry.

My son is 15, I would never put something like that on him. He's killed rats with rat shot. He's watched me clean fish and squirrels. I'm hoping to have chickens next spring. My wife and I have talked about it, I'm going to teach him how to kill and clean a chicken.

Killing always makes me a little sad, as it should. I don't even kill spiders unless it's a black widow or a brown recluse and it's inside a house or shed. I take the ethics of it very seriously.

However, I think that if you're going to eat meat, you should have to kill and butcher at least once. We'd have a lot more vegans and more respect for life.

 

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.

 

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?

 

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!

 

So, I found this stone mantel behind the garage of the 100 year old house we just bought. It was mostly buried in the dirt. Fits our mantel perfect. Some sort of green stone. Was painted black at some point. I'm trying to strip the paint and want to refinish the stone. Area is southeast of Pittsburgh. Father of the man who built the house was an Italian stonemason that immigrated.

Don't think it's slate, has a tight grain and rings when you knock on it.

What kind of stone is this?

 

Cishet male. In no way do I mean offense or have I tried to take advantage of lower functioning individuals, that's just sick. Best I can figure, I'm a typical. Maybe I'm a little crazy; but who isn't.

During a discussion about my son's neurodivergency, I realized I have a 'type' of woman. (Son is technically stepson, but he's my boy.) I tend to be attracted to high functioning women that are on the spectrum.

I've been in four relationships with divergent women, three serious and two extended friends with benefits. I've been in two serious relationships with typical women. Many flings with typical women. Figure that's pretty statistically unlikely.

In my experience, divergent women tend to have a refreshing openness in communication. Painfully honest. Direct. They have some weird stuff that can be alternately cute and irritating. When sleeping they either don't like to snuggle or like being an octopus. (My preference is octopus but my wife only tolerates some side contact.) They like to discuss instead of argue. Sexually adventurous and willing to work for satisfaction. They prefer precision in statements. I find myself writing in an extended way that I don't engage in with other people and try and pay attention to grammar and punctuation. Pretty sure this doesn't apply to all women on the spectrum, just my 'type'.

I dunno, just a strange realization, especially at this stage of life. It's not a fetish, just something that has occurred.

 

Like this is hitting me real hard. I can feel the sadness and the fight. They're good boys and and don't deserve what's coming down. They have some good religion. I'd like to be like these men. We fight for the ones we love.

 

I would really appreciate it if someone would double check me. Sorry for the screenshot. Either the Lemmy code button isn't great or I'm just dum at formatting.

This has local *arr servers available and traceroute shows me going through the VPN.

The largest blue blotch is the ip address of a mullvad vpn server.

Rpi4, Raspberry Pi OS lite.

Mullvad VPN. IPv6 has been nuked. Using Wireguard through wg-quick.

wg2 originates from a .conf file from Mullvad with IPv6 stripped.

Do these UFW settings look right?

Circuit is for controlling the fan on a Raspberry Pi, just on/off according to temp, no PWM. Not sure about the diode as it has a .7V drop and it's a tiny brushless DC motor. No markings on the fan so I measured the current with a multimeter when hooking it up to a USB charger. Circuit was adapted from here using what I have on hand.

Suggestions? Any advice is greatly appreciated!

*EDIT: Confirmed, this circuit works on a Raspberry Pi 4. Base was wired to GPIO 17 and manually tested using commands:

raspi-gpio set 17 op dh

raspi-gpio set 17 op dl

I didn't use a breadboard, just hack-n-slash with the wires coming out of the fan, the leads on the thru hole components, a jumper connected to gpio 17 as a socket for the base/resistor lead, and heat shrink tubing for insulation. Folded it up as I closed the housing. Case combo including heatsinks and fan here.
