I have very little understanding of geopolitics or economics, so these tariffs don't make sense to me, and they don't seem to make sense to most people.

What’s the best steelman argument for them?

I’ve read a bit of Peter Navarro and others who support this line of thinking, but I’m trying to understand: is there a coherent endgame here that benefits the country long-term, or is this just short-term political theater dressed up as strategy?

What would the best possible version of this policy look like if it were smart?

Here is a write up on the forecasted tariff impact, from the team that makes investment decisions at Wells Fargo.

I want to apologize for this joke in advance. It had to be done.

We could take a page from Trump’s book and call them “Beautiful” LLMs. Then we’d have “Big Beautiful LLMs” or just “BBLs” for short.

Surely that wouldn’t cause any confusion when Googling.

Weirdly enough, the ITU already chose the superlative for the bigliest radio frequency band to be Tremendous:

- Extremely Low Frequency (ELF)

- Super Low Frequency (SLF)

- Ultra Low Frequency (ULF)

- Very Low Frequency (VLF)

- Low Frequency (LF)

- Medium Frequency (MF)

- High Frequency (HF)

- Very High Frequency (VHF)

- Ultra High Frequency (UHF)

- Super High Frequency (SHF)

- Extremely High Frequency (EHF)

- Tremendously High Frequency (THF)

Maybe one day some very smart people will make Tremendously Large Language Models. They will be very large and need a lot of computer. And then you'll have the Extremely Small Language Model. They are like nothing.

'The President and the Attorney General, subject to the President’s supervision and control, shall provide authoritative interpretations of law for the executive branch'

That's basically what EOs are already.

cowsaymoo · 6 months ago

Yes it is trivial for the scope of presidential interpretation to extend over the executive branch. And this excerpt posits nothing about the oversight authority of other branches.

The more interesting phrase is about the AG. While the AG is already constitutionally understood to serve at the president's pleasure, this EO curtails any informal independence that the AG is afforded from past norms.

So I suppose it's declaring that AGs under a Trump administration shall serve as rubber stamps with no independent authority to interpret the law, granted via his claimed constitutional supremacy over the executive branch.

Perhaps it is a edict to AGs who've resisted orders from the President recently, to notice them that job title is the most supreme form of legal analysis in this executive branch. IANAL

What is the distance of the LED from the scalp? I want to approximate the amount of irradiance (mW/squared area).

cowsaymoo · 6 months ago

It sits right on the head with a ~1 inch foam spacer. The lens might change the fluence, which I think was a key part of the pending patent. Also 90W is the power draw for all the modules in the helmet. I can ask though what the targeted mW/area is and reply if I can get an answer.

I have so many questions about both apparatuses. 90W input or irradiated? Pulse width modulated/dimmed? Lasers? LEDs? 850nm? 830nm? 810nm?

For the panel, 1800W is a LOT of power to put through 2 feet. Is it actually 1800W? What wavelengths? PWM?

I've been using a NIR belt flipped inside out on my pillow the last few weeks. It's only 6W of 850nm, but I've been feeling less dumb recently. Not sure if it's correlated, but until I settle it for sure, I'm going to keep on using it.

cowsaymoo · 6 months ago

The prototype came with a power supply that is set at 24V, 5A and consumes 90W when running. Not sure how the control circuits work but its pretty simply operated with a 3P2T switch for 650nm/Off/850nm. Each module contains a fan cooled array of LEDs behind a plastic lens. I think it has some thermal shut off protection circuit as well.

I just dug out the spec sheet for the other device and you're right. It says "LED Power Class 1800W", but lists power consumption as 350W.

I really like it's potential to improve the right kind of symptoms when applied correctly and I'm also wary of people with bottom line incentives filling in any scientific uncertainty with miracle cures. But I agree, it's definitely worth using. It's a one time purchase with no side effects, so the worst case risk is just disappointment.

I mean, it is kinda quacky to treat someone with that until it's demonstrated by science. I'm open to the idea that light is an important regulator, but that effect should be easily observable if it's truly effective.

cowsaymoo · 6 months ago

I'm no expert but my gist is that light interacts with an enzyme in the electron transport chain (cytochrome c oxidase). CCO is embedded in the inner membrane of mitochondria, and nitric oxide binds to CCO which temporarily inhibits cellular respiration as a natural metabolic regulation to control oxidative stress. Red and NIR light can photodissociate NO from CCO with the right intensity and wavelength, which restarts cellular respiration and ATP production. The release of NO into the bloodstream can secondarily trigger other chemical pathways involved in vasodilation and reactive oxygen species management.

Edit: found a wiki with more details:

Are there any valid safety concerns with this? Or is it just the simple check: "as long as the wattage is low enough, it's fine."

cowsaymoo · 6 months ago

More is not better. Research suggests optimal mJ/c^2/s dosages for each wavelength. Stuff on amazon is not going to be calibrated at all to dosage or even wavelength. Aside from being ineffective, there aren't dangerous side effects except prolonged exposure if staring into high intensity NIR.
