  • I have no idea how these work, but one hack idea off the cuff:

    You get the light for free. At least when your lids are open; that’s how vision works. A cheap digital watch lasts ages on a tiny coin cell because the polarisation of the LCD, which passes or blocks polarised light, takes minimal energy. Stack up a passive polariser, and the active LCD-like layer, (and maybe a second passive layer?) and you can cast selective shadows on the retina.

    This gives you monochrome “smart vision” in the same sense as a monochrome Casio wristwatch. No idea how to tackle issues of focus at such a short focal length, or achieving any sort of active display let alone colour.

    Maybe the whole thing is a pipe dream crackpot idea.


  • One of the frustrating things about Signal is its extreme compression. I hope WhatsApp laxing up a bit will be the final push to the Signal devs to allow me to send a 30 MiB photo if I want to. Just give me a damn opt-in option buried in a settings menu for Pete’s sake.

    Annoys me to no end that I’m forced to crunch image quality down. The reasons I heard in discussion were to save disk space and network bandwidth. I have no sympathy for either of these points. Have a modicum of digital hygiene and delete old files, and pressure your ridiculous governments to invest and regulate ISPs, then join the rest of the world in the 21st century.
