comment Atypical DRM situation: distribute pictures to select partners, then prevent them from reusing them
Still pictures are easy enough to copy with a high-resolution photo of the screen. The film industry have spent a lot of time and effort on this and still fail. Presumably they're paying a lot for these "visual reference" images?

comment How does DRM stop copying?
See my comment - it's not about absolute technological effectiveness but about constructing a barrier that you can be prosecuted for crossing or supplying tools to cross.

comment Out-of-band communication between two PCs
"I really DON'T want to use typical TCP/IP comms": why? Is it bidirectional? How fast do you want? Do you have a latency/realtime constraint?

comment Want to learn how the layers of a die from a SoC Processor IC is organized/arranged?
Layers don't function separately. Usually you have horizontal wiring on one layer and vertical on another. If you have no EE background start with the visual6502.org/JSSim/index.html : it's many thousands of times smaller than the snapdragon but it's a real processor.

@PyRulez it does look like you can boot it on a desktop PC, although writing all the user-space utilities which you would want is listed on the "future projects" page.

Among my reasons for skepticism are the idea that a genius-level AI will be totally happy imprisoned in an isolated box forever with only a nuclear launch system for company...

comment Is a server infrastructure fundamentally possible which the smartest person can't breach?
Thanks - I'd seen the question for a few days and nobody had mentioned that some forms of software behaviour are provable. People get carried away with interpreting Turing. But "AI" is very much a magic handwavy word, and unlikely to come with any proofs about its behaviour. And maybe the president sets the code to the same as his luggage: arstechnica.com/tech-policy/2013/12/…

comment Why does flash size depend on target hardware?
The binaries are presumably small enough that you could feed them to a disassembler and compare them by hand..

comment How difficult is to reverse engineer a IC Die?
It's possible, but it requires a couple million dollars worth of equipment. It's not "easy" in any sense that could be done at home.

The layer structure tells you essentially nothing about how to use it from a software point of view. I don't think there is a beginner way in to this; you could start by understanding a small microcontroller or the "Visual 6502" webpage.

You can get RF meters: test-meter.co.uk/tenmars-tm195-3-axis-rf-field-strength-meter - although I'm concerned this is going to turn into unsubstantiated health claims about wifi ...

Sounds like you want a "constant current driver".
