  • Encrypted data channels can still be vulnerable to man in the middle attacks. Like when you connect to an unknown host with SSH, and the client pops up a big warning.

    In this case, ICE or whomever sets up a “valid” cell tower that your phone connects to, and they (law enforcement) route your packets onto the rest of the Internet. They can decrypt the 5G data, and see all of the IP headers. They can’t necessarily read the TLS traffic, such as https. But most important of all, they can log all of the IMEIs that connect, which effectively gives them a database of all of the protestors.








  • A while back, people in Florida built an absolutely massive airport in the middle of the Everglades. They wanted to build the next big regional hub covering all of South Florida, but that never happened. So there’s a massive gigantic 12,000 ft runway, huge amounts of concrete apron, and space for a big passenger terminal that was never built. The runway remains open as a general aviation airport, and was until now mostly visited by students to practice touch and go landings.

    My points:

    1. The article summary saying it’s an airport used for training is true, but slightly misleading.
    2. There’s a lot of things about this place that make logistical sense for the type of operation they want to do: cheap rent or land, lots of available concrete, not actually new build (easier environmental impact statement), easy on site access to a massive airport that can support jets of any size, low amounts of air traffic, and secluded from public view.
    3. It’s not actually in Everglades National Park, and they aren’t filling in wetlands, like I’ve seen some say.

  • Several years ago at this point, Congress passed a bill, and that bill was signed into law by the President. What that law says, is that TikTok cannot continue under Chinese ownership. Byte Dance either have to sell the American video app business so that it is controlled by Americans, or they have to shutdown Tiktok.

    Byte Dance did not sell the business, so under the law TikTok has to shutdown. This law was lawyered all the way to the supreme court, and the court said it’s a valid law, and must be followed.

    Despite all of these facts, the law is not actually being followed. And Tiktok is still operating in the United States. There is no legally valid reason for it to do so. President Trump has issued extension after extension, even though he has no legal authority to do so.

    The latest here is the top law enforcement officer in the US telling the app stores, “yes we know it’s illegal to keep Tiktok in your app store, but I am pinky promising we won’t go after you.”




  • Non-Euclidean geometry was developed by pure mathematicians who were trying to prove the parallel line postulate as a theorem. They realized that all of the classic geometry theorems are all different if you start changing that postulate.

    This led to Riemannian geometry in 1854, which back then was a pure math exercise.

    Some 60 years later, in 1915, Albert Einstein published the theory of general relativity, of which the core mathematics is all Riemannian geometry.
