  • I use the back buttons as alternative shoulder buttons.

    My right bumper button broke and I can’t find cheap replacement daughterboards, so bandaid it is. I can’t just solder in a new switch because the leads on the PCB broke. Seems to be a failure common mode for the bumpers if you ever hit the corner or drop it. The way the bumper is designed transfers the full force directly to the PCB instead of to the shell or any actual structural component.
















  • Cameras are (generally) passive systems. They do not send out light and analyze the returns. They just absorb light and reconstruct a scene.

    Radar systems are active. They send out pulses or continuous waves of EM energy at different frequencies than light (much lower) and analyze the returns. They do not need existing light to do their jobs because they’re sending out and receiving their own specific emissions. Because they run at lower frequencies than light, they are able to “see” through certain weather phenomena like fog and are relatively unfazed by darkness.

    That all being said, you can measure things passively and actively. Radar is pretty damn good at measuring distances, as that’s the entire reason behind its invention. I’d say its much more reliable and accurate compared to optical systems.




  • We have plenty of things to be old grumpy grouches about.

    “Those banks ruined the American dream and we bailed them out!”

    “Fossil fuel companies successfully lobbied the government to allow them to poison our planet in the name of profit!”

    “Those Disney crooks consolidated all media and destroyed independent creative ventures!”

    “Back in my day we could afford a house if we saved 10 years of earnings for a down payment and then took out a loan eventually totaling twice the value of the purchase price. You kids have it easy with your rental sleeping pods and low-monthly rate outdoors park subscriptions. You don’t even contribute to furniture or clothing industries because you don’t own a place to put any!”
