  • Computers can really just do two things: copy data and do math. Anytime your your doing anything but copying data verbatim, there is math involved. Anytime your reformating, filtering or acting on data their will be some math involved.

    Take displaying an image: you can’t just copy image data to the screen, because it could have a different resolution, or color space, or be compressed. In all of those cases, you will need to do a lot of math to get things to work right.

    The exact math varies, in graphics, CAD or geospatial stuff, expect a lot of geometry. Any sort of statistics or classifier is going to involve a lot of linear algebra. Even simply storing data in s quickly accessable manner involves quite a bit of math.


  • Does your car lock up outside of cell coverage? I’m not suggesting removing the radios themselves, just the antennas. To the car, it will just always be out of range.

    The antenna used for talking to the keys might cause trouble, but those are either inherently short range inductive systems or are receivable using a 20$ RTL SDR to verify it’s not sending anything else.


  • Should be quite easy to remove any WiFi/cellular/satellite antennas from the car’s computer. (Might be trace/chip antennas, so make sure to get those). If you’re extra paranoid, get the GPS antenna too, so it can’t simply record data indefinitely.

    Might take a few hours to go through the car to make sure you get everything, but you won’t be limited to super old cars.










  • The number 6 is quite nice. It has a lot of factors and is also the smallest perfect number. Unsurprisingly, it shows up everywhere in a number of religions. People might easily have started with the number 6 and designed the star to go along with it. While it was harder to travel thousands of years ago, people did and it only takes one to bring back a design like this.

    We can trace every script in Europe, Africa and Asia back to just three, one from Mesopotamia (3400 BC), another from Egypt (3250 BC) and the third from China (1200 BC). If writing was able to make it’s way to almost every single culture on three continents, a 6 pointed star certainly can.
