  • Wild. I was just complaining that I used to follow Lockheed Martin on social because planes are cool, but it’s recently become filled with missile and other direct weaponry posts. I’m well aware of what the purpose of a fighter plane is. They used to at least have fun posts about the scientific work performed by the U2 and SR71.



  • There’s certainly a tipping point where light becomes too yellow to accurately represent color. I was recently shopping bathroom vanities and some showed what the greens and blues would look like under different color temps, with 2700K just about ruining the appearance. I also painted a room in light blues and had to change the adjustable lights to 3500K, if I remember correctly.

    I’m just intrigued and thinking out loud. I’m having a hard time describing yellower as harsh. I could see the overhead lights doing a better job at flooding an area and minimizing shadows, whereas window light would be diffused but still somewhat of a point-source depending on distance. The “backrooms” image of the empty office space certainly comes to mind where it’s all a vague shade of yellow-green.

    As far as people who can’t seem to see anything under wandering daylight, IME, they tend to be a mix of people who are either older (reduced dark vision, reduced focus) and impatient people (who don’t understand your eyes take 5 seconds to adjust pupil size but 20 minutes to refill rhodopsin, your night vision juice). Or just people who demand conformity. Or a 4th group I suppose, who have max-brightness screens that doesn’t play with eyes well against dark backgrounds. I do personally prefer natural light and wait for my eyes to prove they can’t see enough before using lights, except for when I have physical tasks to do like cook or repair something.

    Apologies for seeming like I was telling you you’re wrong. I was trying to get your perspective but just rambled in my own opinions. Lights are a notable hobby for me, sort of. Headlights, flashlights, night lights, street lights, light pollution, night sight, neon lights, uv lights… I read up on lights weirdly often.



  • Itvs interesting that you find yellow light to be harsh. Normally, the yellower tones (2700k-3500k) are called warm and soft white. Daylight is 6500k with a notable blue tone and neutral white is somewhere around 4500K. Is your office also filled with brown/dirty surfaces that seem highlighted by the warm light or grays that clash with it? Florescent lights (and cheap LEDs) are especially harsh in general because they have really bad color rendering, meaning certain tones get muted and distort perception. Letting in daylight may just be helping restore color vibrance. Bluer lights also tend to have more UV output, which makes them more painful at night. Yellower lights lean towards the red end and aren’t so jarring for the same brightness. Bluer lights get used in hospital, lab, and other high-detail settings for more clarity, while yellower lights get used in more relaxed environments where visual detail is less important.

    I wouldn’t guess you have a different cone count, but I would guess there’s some underlying perceptions about colors and visuals.






  • If I make a gas engine with 100% heat efficiency but only run it in my backyard, do the greenhouse gases not count because it’s so efficient? Of course they do. The high efficiency of a data center is great, but that’s not what the article laments. The problem it’s calling out is the absurdly wasteful nature of why these farms will flourish: to power excessively animated programs to feign intelligence, vainly wasting power for what a simple program was already addressing.

    It’s the same story with lighting. LEDs seemed like a savior for energy consumption because they were so efficient. Sure they save energy overall (for now), but it prompted people to multiply the number of lights and total output by an order of magnitude simply because it’s so cheap. This stems a secondary issue of further increasing light pollution and intrusion.

    Greater efficiency doesn’t make things right if it comes with an increase in use.


  • Standard map projection strikes again. Starting from the tip of South Africa, it’s 4300 miles to Uruguay (where you’d land straight east) and 5300 to Perth, Australia. New York City is 3300 miles to Portugal and obviously the smoothest route to Australia is hopping through southeast Asia. Coincidentally, the northern hemisphere has way more population.

    Cape Town is only 34° south. Going to 34°N, you’re lined up with Los Angeles, Dallas, and Atlanta USA, then Morocco, Algeria, and Tunisia, then the middle of the Mediterranean Sea, Lebanon, Syria, Iraq, Iran, Afghanistan, middle of China, southern tip of South Korea, and grazing below Tokyo. It’s still 4100 miles between Georgia (USA) and Morocco.

    There are no southern polar flights and no southern undersea cables because the southern continental points aren’t as far south as the northern points are north. Population volume doesn’t create the demand for more direct service.





  • I beleive a large issue, and I say this as an old man yelling at kids on my lawn, is the difficulty in learning new systems. Most of those bad ones largely changed how to navigate a pc. Most of the good ones were smaller leaps from the prior bad one. So yes, I’m sure that also means the devs had more time in the current style to smooth it out and fix newly broken features, but it also got people exposed to the new style. A huge problem with 8 was that it went to that tablet tile bullshit. 10 tries to be a tablet too, slightly less so, but now we’re all accepting it as normal. That’s my take, at least as a contributing factor. Whatever was normal in your 20s is the standard for the rest of your life.

    I see it with cars. People in my cohort get mad at all the chimey nannies in modern cars, so they yearn for when cars weren’t so inundated with technology. Peak automotive design was 1985-2005. And yet, the adults when we grew up would complain those 90s cars are way too complicated with their electronic engine control models and emissions systems.
