Trepanning is back, baby! NSFL warning. Dude has his friends help him dremel a hole in his skull so he can like totally open his third eye or release the demon chakras or whatever.
Can’t find it, but there was an interview where someone talked about poking their meninges with a metal rod and having a ‘spiritual experience’ or something. Also, bong rips feeling bubbly in the skull hole.

After a foray into consulting and plant management, I’m back in the shop working with my hands and programming. My favorite part of the trade is teaching kids. (Enough grey in my beard that anyone under 30 is a kid). I could make more money doing other things but I don’t need the stress.
I hope I’m able to work until I die, even if I ‘retire’. I’ve begun learning Blender and mixing it with CAD so that I can do sculpture.
I love the smell of black cutting oil.

Skinner’s glare of disdain would have flayed the flesh from his bones. It would have been a Monster of the Week episode. Mulder would actually help with the coverup and chalk it up to a one time involuntary psychic event. Scully would have cocked her head, pursed her lips, squinted, and said, “hmph.”
- Comment on Littering 🚯 2 weeks ago:
Lead shot for waterfowl hunting has been banned in the US for a few decades. It’s still used for upland bird hunting. I think it’s still frequently used illegally for waterfowl.
Not an expert, but have a decent layman’s understanding. Could totally be wrong about the next part:
It’s my understanding that lead contamination of wild animals through hunting primarily occurs due to various sizes of bird shot. The greater surface area allows a much higher level of contamination. It also forms lead dust in the shell from friction and when fired. It’s also easier for animals to eat it. Rifle rounds and slugs are fairly inert as the larger size prevents most consumption and less absorption when it is consumed.

My guess is that migratory waterfowl eat lead shot when ‘grazing’ the bottom of wetlands. This bio-concentrates the lead in eagles when the prey on ducks and such.

- Comment on The boiled peanut is superior to the baked bean. 4 weeks ago:
Kind of nutty but more like a chickpea/garbonzo than peanut. Very salty, a common variety is cajun. Texture is somewhere between water chestnut and a firm Lima bean depending on how long they’ve been boiled. I prefer them on the firmer side.

It would require Von Neumann machines to do it. Of, course, we could end up being turned into grey goo with that sort of tech.
But, yeah, simply invent self-replicating nanotech. Shoot it at the moon, Mars, Ceres. Viola, data centers in space. Use the same tech to clean up the enviroment and eliminate oil dependence. Might as well rebuld the coral reefs and old growth forests. Also cures cancer and the common cold. And is the fountain of youth. And we all live happily ever after in the computer.

- Comment on I need to vent about plastic milk jugs 2 months ago:
I actually think they’re correct. It explains most of it and jives with my experience.
The amount of plastic used is fixed. Here is a bottle blank I have for a 2 or 3 liter soft drink: Image
We’re assuming that milk jugs are blow molded from a similar blank at the bottling plant just before washing and filling.
Milk bottles are either High or Low Density Polyethylene. A notoriously elastic plastic. It also creeps all over with temperature, you can take a bowed 3" thick sheet of it, put it on the floor and it will usually be flat in the morning, especially if it’s above 75deg F or so.
Milk jugs aren’t a pressure vessel like soft drink bottles.
They’re saying that due to the large surface to volume ratio and thin walls, there is a lot of seasonal variation in final volume. This is primarily due to the compressed air used during blow mold, ain’t nobody paying to heat or cool it. Also, the ambient temps in the plant, in the blow mold area may see 40deg F swing, maybe more, over the course of a year. They aren’t going to pay to condition the air if it doesn’t affect final product. Fuck worker comfort.
This would be enough to show seasonal variation in milk level due to volume changes, especially since the jug necks up and exaggerates differences. Reduced headspace probably also keeps it fresh longer due to reduced oxygen. Mostly, if your competetior’s jug looks more full, you sell less milk. One producer does it, they all have to do it.
It’s a totally believable and logical explanation to me.
- Comment on I need to vent about plastic milk jugs 2 months ago:
That makes more sense. Nothing to do with wear. I guess the dimple would be a removable insert. You could have a selection of them and swap when calibrating the line.
I would think that blow mold is happening right before washing and bottling. Tube blanks are probably supplied in Gaylord’s coming from the plastic producer. Transporting semis full of empty jugs doesn’t make sense.
I’m suprised there is that much variation in volume, I would expect the temps to be more consistent. I guess the compressed air temp is the main variable, mold temps should be pretty consistent. Ambient air temp when the bottle is cooling probably also plays a role, more or less shrink before it “freezes”. Not sure if they’re made from LDPE or HDPE but those are both really stretchy, so I guess they very well could jump all over on size.
Most of my mold experience is in automotive, which is going to be a tighter process.
- Comment on I need to vent about plastic milk jugs 2 months ago:
I don’t think this is correct and would need to see a source before I believe it. I doubt the dimple is adjustable in the way you’re describing.
The amount of wear needed to change the volume by a noticable margin would be quite significant. Surface finish of the mold would be degraded enough that they would probably scrap the mold before using an adjustment like this as the mold would have sticking problems.
It might be volumetric compensation, but I doubt it’s directly wear related.
The mold is going to be at least two parts that split to get the blown jug out. The jug feedstock probably starts as a molded tube blank with the threads already in it. Would look like a test tube with a milk jug mouth.
Thinking about it, and I suppose you could actually call it wear compensation. Machine the mold with max dimple present. As your parting faces/lines take damage, you reface, and take some off the dimple to compensate for reduced volume. Maybe. That’s my best guess if it isn’t structual. Usually the rest of the mold has taken enough damage/wear that you’re scrapping the entire thing.

I really like the interpretation of Cain and Abel having it’s roots in the transition from Hunter Gatherer to Agraian society. Gobekli Tepe and all that.
Another couple of fun ones are Christmas trees being forbidden in Jeremiah and cannabasam (forget where in the OT). I assume your uname is in reference to that cannabis use. The manna as psychedelic mushrooms is also a cool idea.

I like Cain and Abel/hunter gatherer vs agrarian theory.
