They have a device which progressively shines a light on a piece of paper while moving across the page and converts the brightness of the reflected light into an audio signal. Once it reaches the edge the paper is incremented and the process repeats. Each of these segments of sound are sent via a standard telephone connection to a similar device on the other end which uses the sounds to reproduce the image on the original paper on a new sheet of paper. This can be used to send forms, letters, black and white pictures, and even chain letters. It also forms the basic underpinning of a significant fraction of formal communications with landlords, employers, medical systems, government offices, and so on.
For the software side I would recommend Linux Mint as a great simple starter distro with good support and a nice community. The overall design paradigm is about maintaining familiarity while also making sane defaults and simplifying processes. Because it is Ubuntu based it is also easy to get documentation and support because what works for Ubuntu also works for Mint.
For hardware it really depends on your budget and locality as well as use case. Laptops vary much more country to country than you may think, so it may be worth thinking about what is local to you. For example, I live in Australia so System76 is a bad choice here, same with SlimBook (I think that is the name, European KDE laptop that advertises with that French(?) YouTuber, they don’t ship here.
Also, when looking at laptops the RAM configuration is important. If you have two RAM slots but only one RAM stick you will have really slow memory access. This will bottleneck for both the CPU and GPU if you are using both at the same time, say during gaming or doing AI work. Swapping out the single stick for a matching pair or just adding one more stick that matches what it already has will let both ports work together, making everything faster. Also when I say matching I mean in terms of size and speed. If you put 3200MHz and 2400MHz in the system at the same time the 3200MHz won’t just down tune to match, they will both go slower as far as I am aware. Best to match not only the speed but if possible the brand and ideally model, there are lots of little differences between RAM sticks and honestly it has never been worth the trouble in my experience to have mismatched sticks, I just replace with a matching pair.
Yeah, the way they work is based on your eyes seeing two slightly different images because of the difference in their angle to the prisms. By having one image, the full name of the month, shown through the widely diverging angle made when you are closer and a second image, the short version, shown when the diverging angle is more acute you could have the two options visible. Everything in between would be a bit of a crapshoot though, with a muddy mix of both. Your brain likes to figure out images that can make sense, but text can be very weird and in situations like this it would probably be very muddy and more distracting than cool.
What's some amazing technology they have in Japan that's very normal to them but would blow our minds here in the US and western world?
