It is still the norm in the US, especially in rural areas. Unfortunately, cats are absolute hell on wildlife, especially ground nesting birds like quail and killdees. We keep our cats inside, they watch bird TV through the windows.

Hand code is still used. Most frequently, a sub is hand coded with incremental moves and then called at a point. A lot of probing, weird moves, edge cases all still get hand coded.

Hand editing CAM produced programs constantly occurs at the machine as well.

3D printing gcode is pretty ugly because hobbyists "improved" the language without really understanding why it was so stripped down.

Modern Gcode is really meant to be machine generated and human readable/editable.

This is why I don't like the IA+ LGBTQIA+. Q was a good stopping point because queer is such a great way of saying "it's complicated but not straight."

Queer is a nice big tent we can all get under instead of performative labeling or over complication.

They're not wrong. The deaths of Indians from the Americas and the aborigines from Australia far surpass the technical definition of genocide. Throw in banana republics and other nation building and it is totally arguable that the US has been complicit in many other genocides, for instance.

Thanks for the analysis! Looks like the 250th anniversary will be the party line for MAGAts and such. I was sure the anniversary was just an excuse but this is even more black and white.

Makes you feel like you're taking crazy pills watching everyone accept insanity. Grab a Republican from twenty years ago and tell them the president is holding a military parade and they'd want to impeach him.

Read the article but it didn't cover some questions. I haven't paid that much attention to this because the stupid hurts. Thought this was settled science like iodine in salt.

What does mainstream science generally say about the efficacy and dangers of modern flouride in municipal water? What are the MAGAts regurgitating as the reason to ban flouride/what's the conspiracy?

LPT. If you ever get the chance to go to a Waffle House: order a Cherry Coke and ask for a double shot of cherry.

It turns into CHERRY coke and is even better.

As another poster said, Puppy Killer Barbie. I think that has a little more emotional punch.

Damn skippy. Gaslighting and basic ass lying are different things. But hey, it's trendy right now. Next, we'll find out how he's a malignant narcissist.

Dude posted a shill review. It's called shilling. It's a form of lying for profit. He likely did it to advance his career or because he was afraid not to. His employer likely encouraged the action without directly ordering it.

Oh man. Maybe we'll get real AI one day that can write that book. It would have been such a good book.

Nobody better fucking tell Brian Herbert this idea.

Picking up hitchhikers to Woodstock during the summer of '69 kind of narrows it down unless op was one of those maple syrup types.

Steve-O would absolutely swim in a river of shit. He, however, would not allow children to follow him.

 

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!

 

Another before:

It's green Vermont slate, figured out that it was originally painted black and marbled. Victorian thing, faux marble mantels. Fireplace is also Victorian faux, red brick, would have had logs and a red light. I'll be putting in a gas insert at some point.

Started at 220grit, and worked up to 1000. Finished with a 50/50 mix of boiled linseed oil and mineral spirits:

Didn't realize slate could be this pretty and figured:
