Internet matters

I have written before about the cognitive and emotional (and insomniac) downsides of checking the news too often. It seems worth re-emphasizing how twitter is a worst-case scenario in this regard, at least for people more interested in developments in matters of public interest than developments in the lives of friends and acquaintances, where facebook […]

Blair King (whose blog bio says he has an “Interdisciplinary PhD in Chemistry and Environmental Studies”) is one of the people who had sent a tweet arguing that only people who use few or no fossil fuels can call for decarbonization and who I linked to this rebuttal post.

This includes all of your computers (including cell phones, smart devices like TVs and sensors, and network equipment like routers). It definitely applies to website content management systems (CMS) like WordPress. That’s why when […]

The Distant Early Warning line (“Fides Contentio Sapienta”) is part of Canada’s cold war legacy. The DEWLine website has a lot of information on the history of these RADAR sites, how they operated, and who was involved.

One fascinating dimension of software-defined radio is the ability to establish mesh networks: distributed data sharing systems where each computer involved is a node which can carry traffic on behalf of others. That means that as long as you have solid radio links you can establish a network that can transmit information independently from the […]
