I set up an old iPad Air to show https://www.codemancer.com/ for the last two years. It's got a clock, weather, and appointments and is readable from across the room. I've also run into crashes from Safari, which I resolved by automatically refreshing the page once an hour.
After getting tired of constantly searching github and phabricator, I built a small tool that would open git repositories, files, branches, and commits in the browser.

Disclosure: I'm working on a video delivery network company called Dendrio (www.dendr.io).
You're pretty spot on about AWS. Storage is super cheap, but data transfer can be really expensive. Also, depending on your users' habits, you'll likely want a CDN to serve your files, especially if you want to serve international markets, and I can tell you that most CDNs are very expensive for video hosting. Third party hosting like Youtube and Vimeo have limits for how you can use them which are easy to go over while full-service video hosting/analytics/monetization like Brightcove and Ooyala will cost you a house.
Shameless self-promotion: you should check us out at dendr.io. We're working on a peer to peer CDN that runs on top of your existing hosting provider (whether you do it yourself, or a CDN) to decrease your costs and give you other benefits. Feel free to email me at "albert@" our domain.
Brainfuck is just a set of symbols that map to the actions a Turing machine can make. I believe that the symbols themselves were chosen to make it difficult to read and write much like Whitespace. As for Turing machines, I'm sure there are programming books about them but I'm pretty sure their point is about studying computational theory rather than practical use.
From the article they published in Advanced Materials, it seems the ink actually contains silver (the element) nanoparticles in a colloid. I'm surprised that the resistance is still that high.
Making some overgeneralizations here, software written by scientists aren't going to be as good as software written by software engineers. Their usual purpose (and their training/background) is to publish papers and writing code is just a means to an end.
Anybody wondering how long it will take for Bitcoin to gain enough respectability for the FBI or Secret Service to get involved after hacks like this? If the same amount of money was stolen from a normal bank, it'd likely be covered by every news outlet.
