I once had a conversation under NDA (which has expired since) with an engineer at Apple who was working on iCloud infrastructure, and he was telling me that his team was a bit shocked to read that Dropbox was releasing apps for photos at the time âbecause theyâve noticed that most of the files users are uploading to Dropbox are photosâ. He was like: how do they know that exactly? His team had no idea and couldnât possibly find out if the encrypted files they were storing were photos, sounds, videos, texts, whatever. Thatâs what encryption is for, only the client side (the devices) is supposed to know whatâs up.
Not having that information meant a direct loss of business insights and value for Apple, since Dropbox had it and leveraged it. But it turns out Apple doesnât joke around about security/privacy.
Custom-made ear plugs. Even if you only wear ear plugs occasionally (I do when in a noisy hotel, or when a neighbor goes a bit too crazy), they are so worth having.
Basically you go to an audiologist and they put something kinda liquid in each of your ears to take a mold of your ear canals. A couple of weeks later, you have plastic earplugs that have the exact shape of your inner ears.
Upsides: ⢠They work, always. I would typically use wax or silicon disposable ear plugs before that, and sometimes in the middle of the night they might move and let the sound in; those donât. Also, foam disposable ear plugs donât stay in my ear, donât ask me why. ⢠They never hurt. Since disposable ear plugs get shoved into your inner ear until they take the shape, they continuously push against the walls of your ear canals. I would often feel kinda bruised after using them for a long time. ⢠They are crazy comfortable. Put your ear on a pillow, and you barely feel them at all. ⢠But do they block too much sound? Thatâs up to you. Basically, you choose the level of noise you want to keep out, which I believe is achieved by using different kinds of plastic.
Theyâre not a trivial purchase (I think mine cost $150), but then you use them for decades, so itâs definitely worth it. It was a stupid purchase in my case, because I bought them on a whim out of anger against my neighborâs party one night; but theyâve followed me everywhere since!
