Comment Re: modern cars are less safe (Score 3, Interesting) 180

Some things like an unclosed door signal are super useful, but some things are so annoying... Last time I rented a car in the US, I had to stop and read the manual after a mile because it was unbearable: it beeped when a car was passing me, it beeped if I didn't use my turn signal *after* passing a car (who does that ?), it vibrated in a scary way if I got close to any line, it beeped if I got 1mph over what it *thought* was the speed limit (many streets were wrong), and so many other things. I spent 15 mins in the manual to disable it all, and it was like 5am for me due to jet lag.

Sure you do. The human eye doesn't have enough rods and cones to resolve the kind of detail you're talking about at the distances you imply so unless you're a genetic freak you're just another tedious troll.

Oh dear... you seem to think that the human eye takes a picture like a camera. That's not at all how our eyes work. The number of rods and cones is not really that important, density of them matters more, but the focal length between the front and back of our eyes matter the most.

You see (pun intended) the human eye and brain work by scanning and filling in the blanks. Your eye is scanning (micromovements) constantly. Your brain is storing what it saw in an extremely narrow field of view and building up a mental image that makes you think you're seeing everything around you in one shot and in high detail. Nobody is. We're all seeing a very tiny sliver of high resolution dead center of our vision (well minus the tiny blind spot where the optic nerve leaves the back of the retina), and the rest is composited together from memory, and some of it is hallucinated (or inferred by experience and the brain being lazy).

So you are correct that it is unlikely the person can actually see such detail at that distance, but in theory, if his eyes are able to focus light just right at that distance onto the important part of his retina, he theoretically could make out the pixels, even if the pixel density is higher than the density of the cones and rods on the back of his eye.

My guess is he really believes he sees the individual pixels at that distance, but what he's seeing is artifacts from groups of pixels that his brain perceives. Not too dissimilar to how many people (myself included) can tell the difference between a CRT monitor refreshing at 60Hz, 75Hz, and even 85Hz. We're seeing secondary effects and claiming we see the flicker. Heck, anything below 400Hz for a fluorescent tube light and I absolutely see flicker, yet physiologically I should not. Clearly my eyes don't refresh at 400Hz. Just like the OP's eyes do not have the ability to resolve the pixels at that distance, but his brain is treating secondary artifacts as pixels, when they are very likely groups of pixels that appear to show banding in his vision (a common issue with human vision, and the reason why sub-pixel blending is used on fonts, to avoid that exact phenomenon).

So yeah, the OP is confusing his perception with what he is physically seeing. Lots of us think we see details we don't actually see. Our brains are fantastic at guessing and seeing patterns, then convincing us that we are indeed seeing them. That's the foundation of most optical illusions. And if he really did have a genetic abnormality where he could resolve the pixels at distance as he claims, then he'd be blind when looking at anything at any other distance as he'd be unable to focus the lens of his eye due to thickness.

Comment Re: Don't be stupid, people (Score 1) 47

The hidden costs - especially on up-and-coming devs - is the fact that knowledge isn't being retained so a solved problem will end up being re-solved by LLM again. And again. And again.

Worse yet, given how human creativity works, this means we won't see novel applications or solutions. Just layer after layer of mostly functional AI slop

Funny thing is, the more AI consumes all of our CPU and RAM for their data centers, the more necessary it is to build performant and optimized code, both for CPU cycles and for memory constraints, since consumer devices are going to have worse compute resources available going forward due to cost.

The dinosaurs among the devs (of which I sadly count myself as one), know how to write code that squeezes every bit of useful work from every clock cycle, and how to use the least amount of memory necessary to achieve the task at hand. So the more layer after layer the AI slop generates, the more job security actual skilled developers will have.

Comment Solar fridge (Score 2) 34

I want to note that it's long been possible to make a solar fridge at night. You know the solar ovens that use a parabola of mirrors and heat water or a sausage at the focal point if you point it at the sun ? Well, if you point it vertically at the night sky on a clear night, the black body radiation emitted by your water at the focal point will all flow to the sky and it will cool a lot faster that if it was simply lying on the ground.

Comment Re:Get it right (Score 2) 95

That's the thing: it's a matter of preference. I like that on KDE I can put the task/menu bar anywhere I want. I hated that on Windows it HAD to be at the bottom; well I don't care anymore because I don't even have a remnant of Windows anywhere. On those long narrow screens I put it on the right and it it's a VM it goes on the left, so this way if I'm in a maximized VM I know immediately.

Comment Remember XP SP2? (Score 1) 102

The same sort of sentiment was expressed before Windows XP SP2 was created. When MS actually puts effort where it's needed, and let's engineers develop solid solutions, and not just listen to the marketing department and force unwanted changes on us, they are quite good at making a solid product.

I'm very hopeful this will be a repeat of the XP SP2 experience.

I will admit I'm not willing to bet on it though... but no harm in being optimistic. Cautiously optimistic... or is that just wishful given their track-record?

I could never get over the fact that if you've never borrow money and never used a credit card, you have a shit credit score...!?! It should be a perfect credit score instead ! I borrowed money for the 1st time when I was 35 and I had only ever used debit cards before and I couldn't find anything better than a 17% rate loan. What a fucking ripoff.
