ridgeguy commented on America has a tungsten problem   noleary.com/blog/posts/1... · Posted by u/noleary

Caught my eye due to family events. One of my uncles was killed in the Pine Creek mine in California. He was repairing an ore crusher when somebody switched it on. Pre-OSHA and tagout days.

I doubt we'll be pinched by tungsten shortages. The fusion application isn't going to come on for at least two decades. Smaller apps will be met by known reserves.

That said, it is a cool material. Looking for aluminum bars at Alan Steel (CA) years back, I was stunned when I tried (and failed) to pick up a 12" long by 6"diameter piece of what turned out to be tungsten misfiled in the aluminum section. Density, thy name is tungsten.

> Something is systemically wrong in the US when we are cutting off people’s access to meds, like GLP-1s, which have profound health benefits.

Are we cutting off people's access to meds or do they just not want to pay what they cost?

Are there any interactive elements to this? It looks like a noninteractive presentation of the book as a webpage.

Scroll down a bit. Interactive elements were below "Definitions" on the page I tried.

One of the most annoying things after installing Tahoe for me, that for no good reason an ordinary app would randomly lose its focus. In the midst of my typing. This is unbelievably preposterous and I just can't stop hating Apple for this crap. How the fuck this is acceptable? I just have no words. What makes it even worse that I couldn't even complain about it on their support pages - they just keep removing my comments for being "non-constructive". This is some random bug, and many people have complained about it, how am I suppose to make it "more constructive"? Send them the exact configuration of constellations, the number of monitors I use and their positioning angles, log the keyboard rate and delay, the latency, the level of magnetic interference caused by my Bluetooth devices, etc.?

Interesting. This is exactly the problem I've begun to have on my 14" M2 MB Air. I'm on 15.7.3. The issue started with 15.7.1.

Here I've been thinking it's a hardware problem, like some sort of mechanical intermittent. Maybe not.

Before I quit riding my motorcycle, I recalled one important thing: all the way from the Oakland Hills to downtown San Francisco, many (I dare say 'most') drivers would step their cars to the edges of their lanes to make room for me to lane-split. I know there are lots of people who use their phones will driving, but this was clearly intentional, and a large number of people would do it. I was riding a Ducati but in a modern car you won't hear me. So that means that this large number of people were:

* checking their mirrors

* deciding to make room for me

You don't have to make room for me. I can lane split with a car in the center of its lane and I can slow and stop if its close to this side. But people would do it. It's just an everyday kindness - a small measure of friendly consideration and I appreciated that.

Still happens. I drive every other week from Sonora my office in San Jose. Hwys 108/120->205->580->84->880 and back. People are surprisingly (to me, anyway) aware and accommodating of lane-splitters. Gives me a little happy flash whenever I see it.

Where will the planes land?

Dry lake beds abound in the US West. See Edwards AFB (big dry lake bed on which nearly everything, including the Space Shuttle, has landed). See also Groom Lake. These are enormous and couldn't be wrecked by conventional runway denial weapons.

Yeah, the body-wide mucous thinning properties of NAC are one of the reasons it has racked up papers showing its efficacy in a truly staggering number of illnesses and conditions. (Including neurodegenerative diseases.)

Highly recommend reading the actual literature on its effects in regard to cystic fibrosis, pancreatitis, COPD, neurodegenerative disorders, high blood pressure, ulcers, IBD, liver and kidney problems, OCD...

The list goes on at a pretty extreme length, and it sounds too good to be true, but the papers are out there.

Can you suggest a review article or two? Interested in this as my dad passed from hemorrhagic stroke, my mom from occlusive stroke. Thanks.

What are you going to bling out?
ridgeguy · a month ago
A bunch of devices (laser diodes, microprocessors, high power RF GaN amplifiers) that'll run lots cooler on diamond heat spreaders; diamond Raman lasers (high efficiency & power); large single crystal diamond wafers - nothing most of us would pick up off the sidewalk, but might be very important.

I do have 3 CVD gem brilliants (blue, pink, colorless, 2ct. each) that a local jeweler is putting into a 30th anniversary piece for my wife. That makes me grin in anticipation of the surprise gift - my kind of bling.

Happy New Year from the Sierra Nevada foothills.

2025: - set up new facility for mfg of CVD diamond tech products - replaced awful old carpets at home with bamboo wood floors - lost 42 lbs (thanks, tirzepatide) - secured $ for a new CVD diamond system, build starts in January - road trip to see friends & family, some for first time in a decade

Wishing happiness, love, accomplishment and adventure to all!

ridgeguy commented on Researchers discover molecular difference in autistic brains   medicine.yale.edu/news-ar... · Posted by u/amichail

I do indeed. Because developmental windows exist. You can take the cat out of the vertical world, but you can't take the vertical world out of the cat. Trying to train them out of it only helps a little - too much damage is already done. The brain has developed a certain way, and you can't un-develop and re-develop it.

There is no consensus that autism is like this, but a lot of evidence points that way.

We'd need at least a generational leap in neuroscience to be able to pull off something like that. It's not a "laws of physics prevent you" level of impossible - we just don't have a clue of how would we even begin approaching something like that.

Hubel & Wiesel's work is fascinating, but may not map well to more complex systems (not dissing cats, they're plenty complicated!).

For example, humans clearly have a window for learning their native language. It just happens, and it's nearly magical. But humans can learn non-native languages after that window slams shut. We vary in our ability to do that, but if it matters, most can pick up useful conversational and reading skills.

I agree it's a matter of research. I think we've barely begun to scratch the surface of what's possible.
