I hadn’t heard of EndMyopia but it sounds plausible to me. I have been myopic around -6.5 diopters left eye and -5.5 diopters right eye (with astigmatism) for almost 2 decades now. I discussed eye health and preventing worsening / pote

I’m a big fan of vernier scales from my machining days, and it wasn’t until I read this site that I learned why: human vision has what’s called “vernier hyperacuity”: the ability to detect slightly misaligned line segments at up to 10x the

The Retina value is “for a specific visual acuity (usually 20/20), at a specific viewing distance (usually 18 inches), at a specific brightness (usually indoor office lighting), individual pixels cannot be distinguished”. If you have b

One exciting thing about microLEDs is they can achieve much higher pixels per inch. Before Apple’s big Retina push, PPI was around 80-120. It went to around 200-300 with Retina. Researchers making microLEDs in the lab have gone as high as 6

I love good dives into an increasingly-optimized process like this. Particularly the “here’s what the output looks like after each improvement” images, they are very satisfying. If the current improved form still had some difficult edge cas

Would the likelihood of a crash be the same between a Civic and an Aventador? A priori, I would assume they would be different. By how much, I don’t know - but I imagine the insurance companies do know, and they’re pricing the insurance res

I mean, a quick search of insurance prices for cars said $1700 for a Honda Civic, $2200 for a Rivian RT1, and $7800 for a Lamborghini Aventador… so I think owners of expensive cars are indeed already shouldering the extra insurance costs? T

Its magnitude is roughly about one quarter of the low end predictions for sea level rise, yeah. Not much, but worth factoring in.

I believe keying is now generally discouraged since it necessarily involves weakening “good road” around the pothole by undercutting it and replacing it with cold mix, which is fundamentally weaker stuff.

Hasbro (who are actually the Comcast of table top games) bought WotC in 1999, initially operating it as a legal subsidiary. I only followed MtG from 2001 to 2005; at that time it seemed pretty clear to me that Hasbro was taking a fairly h

Cold mix, also known as “blacktop repair”, will repair potholes. I’ve worked with it before, I recall the packaging claims it will last 5-10 years. This is slightly misleading: if you cut the pothole edges square, make sure the base of the

Of course! It doesn’t have to be verbatim or credit me in any way - if you like the idea, run with it, rephrase it, etc. If you’re familiar with the WTFPL, that’s the spirit of my comments.

It’s become popular knowledge that the way ducks mate is almost all non-consensual. Less well known is that something like 90% of all orangutan mating involves violence by the male against the female. If we ended rape among ducks, or ended

Doesn’t seem like a dumb argument to me, although I don’t think net neutrality would have actually interrupted or replaced most of those peering arrangements in practice. If you’re pushing 15% of all internet traffic you’re going to end up
