  • 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!”




  • The bottom 20% of earners aren’t likely to make the same amount in CA vs TX.

    California’s minimum wage is $16. Working 40 hours (hard on a minimum wage job for reasons) brings $640 a week. 10.5% of that is $67

    Texas’s is $7.25. 40 hours of that job is $290. 13% of that is $38.

    In this bad example, a minimum wage earner in California pays almost double the tax than a minimum wage worker in Texas. It’s a bad example for many reasons, including us not taking into account the extra spending power the California worker has after taxes.
