    A pinhole camera has no lens. The effect here is like a pinhole camera, but a pinhole camera is nothing at all like a lens. Pinholes diffract light. Lens refract light.

    EDIT: Of course you can’t resolve an image through diffraction. That’s not how pinholes cameras work. Diffraction negatively impacts image resolution, but it absolutely happens when light passes through them. But, although lens do use refraction to resolve an image, that same process also has unintended negative effects on image resolution (spherical aberration, chromatic aberration, etc.). I didn’t bring up any of that because it was ultimately a distraction from the important part: narrow gaps diffract light, lens refract light, and pinhole cameras do not work like lens.







  • There is a reason that I have fallen asleep during the extended 3rd act fight scene in every single god damn marvel movie since Mark Ruffalo became the Hulk.

    They all turn into the same movie, with the same fight. And these super long fights all seem to be surprisingly light on showing any of the actual real world impacts of such violence. Nobody ever gets seriously hurt unless the plot needs more sacrifice. But even when they do, the injuries mostly happen off camera and the blood never flows or spurts, it just instantly appears as makeup. It’s really giving people a deep rooted and totally unfounded sense that violence both solves every problem (it doesn’t) and does so bloodlessly (it doesn’t). At least Batman knows he’s not a hero.

    But really, the DC universe isn’t much better. Think about how shocking a little bit of blood at the beginning of the new Superman movie was, before they basically destroy metropolis (which was rather expected and mundane). And then they only show the tiny fraction of people personally saved by Superman, not the countless mangled corpses buried under rubble. This may be why the public has trouble confronting the realities of war and violence.









  • My smartphone isn’t a phone with “extra” features to me. My smartphone is a portable personal computer with extra sensors, a GPS receiver, and wireless internet, which also happens to have a phone app. I don’t want to carry an extra “dumb” phone. I would prefer my smart watch to be the communication and identity hub for me and my devices: holding the SIM card, acting as a wifi hotspot, routing calls and internet to my handheld brick or laptop, etc. Instead of acting like a third party add-on, it would be a mostly distraction free core. Let me use a smartphone, laptop, steam deck, cobbled together cyber deck, or whatever else have you as my local screen, storage cache, and/or proper desktop. Then I can put the screens down or leave them behind without feeling cut off or potentially stranded in a world that practically requires it to navigate with any ease. I want a smart watch that enables me to leave the house without car keys, driver’s license, and credit cards; essentially with nothing but my watchphone. I want to be a cyberpunk Dick Tracy. What I want, with the freedoms and open standards I want, with the privacy I want, without being locked into a single monopoly walled garden, is probably a pipe dream. I want what is probably the next evolution of the “year of the Linux desktop”. But a kid can dream.
