    It is not some big conspiracy.

    Wired headphones have many pros, but also many cons. Wireless headphones have many pros, but also many cons. You can still buy wired headphones for modern phones using USB-C.

    The vast majority of people literally don’t care or prefer having wireless air buds. The people who don’t, still can have wired ones.

    The major distinction is that the headphone jack is large and not easily waterproofed. The trade off of having a sealed water tight phone at the cost of losing the headphone jack is worth it for the vast majority of people. It is worth it to me.

    If you don’t like it, go buy a Zune.

    It takes 8 minutes for the light to travel from the sun to Earth. Because light in a vacuum travels faster than anything, including information, we would not and could not know it had disappeared for 8 minutes. This means Earth would continue to follow its orbit around a non-existent sun for 8 minutes because the Sun’s gravity would still be acting on the Earth.

    If it was nighttime, you wouldn’t notice the sudden lack of sunlight (other than if it was a full moon) but you’d almost certainly notice the change in gravity.

    Edit: actually, you wouldn’t feel any difference in gravity or experience any change of acceleration. What you would experience is a very tiny vibration, of 1 million push notifications being sent to your phone from the other side of the planet.






  • Reinforcement learning is a machine learning (ML) technique (“AI” in layman terms) for optimizing neural networks and other types of non-linear models.

    As far as ML math goes, this is fairly tame. It looks complicated, but is spelled out clearly in the paper. A lot of these kind of theoretical papers — things that would get published in Automatica — are going to lean very heavy on math.
