Just to be clear, I don't think that low-power EM radiation poses a health risk. I am just saying that if you are worried about it (like OP is) you can simply reduce your exposure to it. Doing so is relatively easy and has a minimal quality of life impact. As others have mentioned, low-power EM radiation in the frequency range used by cellphones is non-ionizing, so it can't cause cancer or severe health issues in the same way that ionizing radiation can.
At the present, we don't have enough evidence to be concerned about low-power EM radiation. However, this does not rule out the possibility that in the future, we might find a causal link between that kind of radiation and adverse health outcomes. What we do know at the moment is that this type of radiation can heat tissues. What are the long-term biological consequences of that? We don't really know. My advice: try to minimize your exposure out of caution, but don't get too worried about it.
If π is a normal number, then it contains all possible sequences. However, it is currently unknown whether π is a normal number. I agree with you regarding the fact that this might not be a great compression algorithm, but it is certainly fun.
I became curious about this and went to the book to learn more. The system proposed in the book is capable of radiating around 2.2 x 10^-29 W by rotating a bar weighing 500 tonnes about 270 times per minute.
I just created a little tool to aid in the reverse engineering of the system that generates the URLs for each custom video segment. The filenames of each video are the result of hashing an "options" string plus a pepper value; this tool takes care of the hashing.
Yes, it is possible to use pf to do that. That is why I mention that it might be a good idea to use the script in conjunction with strict firewall rules.
