The ice created has an index of refraction of 1 and extremely low surface reflectivity. It is almost impossible to see and can appear anywhere within 5 meters of you.
Implying he isn't right wing anymore, or just not openly?
I agree with most of the stuff he says, he just doesn't seem very nuanced and I find the angry tone slightly off-putting. I like NJB tho, probably because he's just sarcastic at some points for effect.
It's for transferring pictures over the wifi network or a local wifi network that the camera is hosting. If you have the SD card plugged in, there's absolutely no reason to use the app instead of your phone's file manager. I don't even think the app will recognize an SD card, but I don't really know. It might recognize a plugged in camera, but it doesn't advertise that and I've never tried.
There's not really anything you need the app for. It can remote control the camera with a live feed, which is cool but not all that useful, at least for me. It can also transfer images and videos, but I'm not sure it does the videos at full resolution, at least in my camera. For all practical purposes it's just a little less useful than carrying a USB C SD card reader around with your camera that you can plug into your phone (because it also takes a good minute to connect usually, but my only datapoint is a camera from 2014 so they might have improved it since then)
I recently switched to Android. IPhones work great, the hardware is all there, the software is probably more polished, etc... but on Android you can get the phone to do basically anything with a bit of effort. There's an app that lets you easily install most linux packages, and one that can emulate most Windows apps and games. There's a ton of open source software, and you can actually find apps that don't shove in-app purchases in your face (because devs don't have to pay $100 a year just to stay on the store)
I got PrusaSlicer to work on my phone, through the Windows emulator, and sliced one relatively complex 3D model with it. For some reason it crashed every time I tried to start it after that, but it's still pretty neat that it worked at all. PrusaSlicer has a linux build for ARM so whenever I find the time to set up one of those linux desktops on my phone I'll probably try that.
Fedora and Arch both work pretty well on 4gb. Plasma and Gnome were surprisingly decent, and xfce was great but a little uglier. Blender, FreeCad, Minecraft (with performance mods), Celeste, for example all worked perfectly fine, with maybe a few browser tabs in the background as well. You couldn't do anything too heavy, but it was pretty usable (I was using it as a travel laptop mostly). I'd say 2gb is where it becomes too little to live with.
I got a HDD very recently for a backup drive for my server and I'm very happy with that decision. 8 tb, lightly used but an enterprise drive, for $100.
You're still perfectly visible in shadows and reflections. Anyone who catches you in a mirror will see you completely naked.
Ambient light occlusion counts too, the area covered by your feet looks perfectly black.
Edit: You can create this scenario pretty easily in Blender. Here's what it might look like:
