I always get excited by new Bluetooth mesh network technology because it is extremely useful for pro-democracy movements. Wherever the Internet could be censored, monitored, surveilled, or shut down due to security reactions to social movements, protests, rallies, and marches, a Bluetooth mesh network like FireChat, which was used throughout the 2010s in Hong Kong during the protests against Chinese authoritarianism that came to be known as the Umbrella Movement, can keep communications flowing to a large group of organizers in the field, avoiding confusion, the fog of war, and other roadblocks. Mesh networks are equally useful for underserved areas in rural or urban communities. There have been some successful examples. One in particular comes to mind of an urban community that installed local Internet through a Wi-Fi network that was based on mesh networks. Now, of course, the ideal mesh network would simply involve every...
Geoengineering rests on shaky foundations and poor social planning. I think there’s evidence of the government trying to obfuscate information by changing the names of programs and initiatives, to try to render information exposed to the public in previous reporting facially out of date. First off, this is reminding me of Naomi Klein’s chapter on geoengineering, which is very skeptical of the whole idea, as we should all be. Some highlights from that chapter: Alan Robock wrote a paper published in 2008 in Geophysical Research that geoengineering would “disrupt the Asian and African Monsoon and Pacific Monsoons, reducing precipitation to the food supply for billions of people.” Computer models show that geoengineering would crash crop productivity in the Sahel, leading to desertification. Further computer models show a 20% reduction in rainfall in the Amazon from geoengineering. Historical evidence connects volcano eruptions with droughts, meaning we would be risk...
