I didn't know if treatments targeting amyloid directly would improve memory, but this tests both in one study, which is pretty great--big effects on memory and amyloid plaques. Also, I think Ruth Benca at UCI can measure amyloid levels

We know the ipRGCs receive cone and rod inputs and that non-melanopsin responses (from rods and cones) drive a lot of the reaction at lower light levels.

Remember it takes 100ns to get a value from main memory (after you miss all the caches). With random-access data structures the total size tells you the speed. Here's a test to see how your CPU does: https://github.com/

Yes there is samba support in the latest version too. This is not a solution for "every Macbook customer" though.

Would definitely like to see the GC writeup. Are there patterns where replacing or expanding values use lots of storage or where things slow down waiting for GC?

An incandescent/halogen will go to warmer temperatures when dimmed. So it might start at 2800-3000K but be 2100-2200K at 1% brightness.

The message is: there is no more risk from LED than older sources, by the metrics we have now. I would suggest that one problem is that LEDs don't "warm dim" (unless you get some special ones from Philips and a few others), a

Yes, lux depends on the viewing distance. Lumens is related to total light in all directions, and lux is "per area" (i.e. gets smaller with 1/distance^2). Melanopic is weighted by the non-visual response in the eye, and this

You might want to refer to our measurement project for some numbers: https://fluxometer.com/rainbow/ Also, you can be below threshold for circadian responses just by being very dim.

Yes, also if your eyes are closed when it starts, 500nm is better because more gets through the eyelid. Better if you diffuse more and spread out the light over more of the visual field. But the main thing you'll want to make sure is t

If you are curious, the smallest doses where "blue light hazard" has been observed in humans (short-term exposure) are around 10 J/cm^2. International standards use around 2 J/cm^2 for a safety margin. One example of thi

f.lux author here, still slogging through the article. It is hard to understand the light levels used because they use "power" (uW, mW) from a laser, and not "irradiance" (uW/cm^2 or mW/cm^2), so which area the
