  • This. Aegis does all of the points except offsite backups. And for good reason.
    The Aegis app has no network permissions at all, which is obviously a massive boost for security and privacy. And besides, off-device backuping is a nightmare.

    Syncing the Aegis backups made on change to some other server is better handled by a great dedicated app. Syncthing is the best such program (by far), though for the few files involved here nextcloud would work just as well.


  • I assumed he’d estimated it based on how distorted the face appears behind the glasses. I do that all the time.

    At this angle it’s hard for me to do that, since I usually use the edges of the face to estimate it. negative glasses pull the line inwards, positive outwards. I can reliably tell when someone is wearing fake glasses (0 strength) for example, and probably estimate strength within 30% of the actual value.

    If the image was higher res maybe I could estimate this case too. Or this professional optometrist is just a lot better at it than I am.


    Strong negative glasses: (Note the faces contours in the glasses appearing well inside the faces contours around the glassed)

    Fake glasses:

    Positive glasses:


    PS: Searching for generic terms yields 100% fake glasses, so I took a specific person I remember having strong glasses for myopia.






  • Clarity can also be achieved with a 4k panel. Once your panel gets over 600ppi it’s gonna blow an eink screen out of the water at its own game. Those phones were barely ever made only Sony even tried. Probably due to battery life, or maybe noone realized what they do to the reading experience.

    Either way we’re gonna improve battery life and maybe even get microled before eink ever gets competitive with emissive screens. Someone is bound to rediscover that you never truly needed eink for comfortable reading, just a significant increase in resolution.







  • It’s also completely fine under all international law.
    Following copyright law is more like a trade agreement, so if you feel wronged enough as a nation it’s completely uncontroversial to suspend all or all international copyright law and deal with the consequences (mainly the us being very salty about it).

    The EU contingency for a US attack on Greenland for example is among other steps to suspend all US copyrights recognition and starve the US service industry.

    Most lenses only care about the angular light distribution, essentially averaging over the lens surface. So a ding or crack would just add a tiny portion of grey or black to the entire image

    Edit: This is for cracking the front protective glass of a camera lens. If an actual optical lens splits in two it will be misaligned and bad things will happen.
