That seems to be a bunch of boilerplate surrounding a Salon article from 2015: https://www.salon.com/2015/09/26/how_to_explain_the_kgbs_amazing_success_identifying_cia_agents_in_the_field/ It also contains references to supplementary material, like whether Intelligent Design can be linked to information theory: https://mindmatters.ai/2018/10/does-information-theory-support-design-in-nature/ I am not sure this issue is on topic for this list. > There was a paper that looked a traffic morphing published a year > or two ago that came to the same conclusion, to look like you're Skype or a > SIP VoIP call you need to actually be Skype or a SIP VoIP call. > You could link it, perhaps. thanks, Rob
