    Engineers at NASA’s Jet Propulsion Lab make a breakthrough in rotor technology

    I'm sorry, I can't hear your sub over the sound of my own planes orbiting above! Could you repeat that ping? And one ping only, please.

    The US military just released a bunch of UAP files, but there’s no there there

    Don't forget, you don't need constant acceleration. If you get up to .99999C then for every year that passes for you, about 4100 years will pass for outside observes. Now, I doubt anything could ever carry enough energy to accelerate to that close to the speed of light. Or I should say a SHIP. A...

    Google unveils screenless Fitbit Air and Google Health app to replace Fitbit

    Not a ton of experience there. My daughter is still using her mother's Charge 2 that is several years old and it holds at least a day of charge (she charges it every night). I think her mom still uses a Charge 3 that I think she got about 3 years ago? I think? My Inspire 2 was going strong...

    Google unveils screenless Fitbit Air and Google Health app to replace Fitbit

    I mean, an apple watch could make that call. This device can't. Also, unless you have your phone on you, you possibly aren't in bluetooth range anyway, so your fitness band isn't going to be alerting anyone that you feel and can't get up. In fairness, my inspire 3 might not be in range of my...

    Engineers at NASA’s Jet Propulsion Lab make a breakthrough in rotor technology

    They are and because of the dual rotor design of them, they are extremely efficient. Supersonic isn't always less efficient. As another commentor pointed out, if you get things well above supersonic, they can become more efficient. It just depends on the propellor design. You do NOT want things...

    Engineers at NASA’s Jet Propulsion Lab make a breakthrough in rotor technology

    Beyond that, it would be wasting charge flying there and back. Easier to just carry the entire mass with it. Round trip communication time is already going to significantly limit what each daily flight can do, unless you plan the entire thing by "AI" to just send back data and hope that the...

    Engineers at NASA’s Jet Propulsion Lab make a breakthrough in rotor technology

    Quick question on clarification. The weights listed in the article are EARTH weights, not their weights on the planet/moon in question. Don't get me wrong, still impressive, but lofting 1 ton, in an atmosphere four times as dense as Earth's, with about 14% of the gravity of Earth is a LOT...

    Engineers at NASA’s Jet Propulsion Lab make a breakthrough in rotor technology

    A TU-95's fan blades also spin with supersonic tip speed. No hearing protection = quickly going deaf inside the thing. It is the loudest prop plane in the world (and generally one of the loudest planes period). Supposedly, and I think it is likely true, US subs can detect the things on sonar...

    Are you implying space Nazis? On the MOON!?!

    Google unveils screenless Fitbit Air and Google Health app to replace Fitbit

    I am not saying I disagree. I just don't see a large market for this. The differences are so small, but the functionality drastically less for a device that is, as you pointed out, nominally the same cost (the Inspire 3 is generally always on sale. Okay, this new fitness tracker might be too...

    Elon Musk tried to hire OpenAI founders to start AI unit inside Tesla

    I wanted to add, a note here too. Now this was under NY law, not federal, but the legalesse isn't that far off. this was what the trump organization was sued by NY over, was that the charity was not actually functioning as a charity as defined, but was for the sole purpose of enriching the family.

    Elon Musk tried to hire OpenAI founders to start AI unit inside Tesla

    To add, there is nothing wrong with charities having assets in for profit companies. MANY 503(c)3s own portions of for profit companies. It is one way they can advance their charities (because income/value). Just like me owning shares in a for profit company is one way I can build wealth. A...

    Google unveils screenless Fitbit Air and Google Health app to replace Fitbit

    Okay, I can buy that. IMHO, I mostly don't look at my health data at all. I use my Inspire 3 as a watch that also gives me text/call notifications, which is very important for me because I often don't notice my phone ringing (I always have it on silent and don't always notice it vibrating in my...

    Google unveils screenless Fitbit Air and Google Health app to replace Fitbit

    Some people suck at charging things regularly. I am not great at it. No, not seeing the battery status probably isn't a huge deal. But if you do suck at it, you've got no idea it is dead if you are bad at charging. Losing everything else to me is a bigger deal. Zero functionality without a...

    Elon Musk tried to hire OpenAI founders to start AI unit inside Tesla

    Yes, and under US law, generally, a non-profit can convert to for-profit status. The only times it can get REALLY sticky is if the future for-profit company changes how, it is using a guided donation from when it was a non-profit. While it was a non-profit that is true. Of course, once it...

    Google unveils screenless Fitbit Air and Google Health app to replace Fitbit

    Yeah, I am missing a lot. My Inspire 4 appears to be almost the exact same dimensions. It also only requires charging every 7-8 days and HAS a screen (MAX 10 days). It does all of this, but with a screen. And IIRC, it was $129 2 years ago? $119? So you lose the ability to tell time, or see your...

    Trump admin censors more studies conflicting with RFK Jr.’s anti-vaccine views

    And also the young. I will never believe that "the sins of the father" are something a child should suffer for. Just because their parents are irredeemable idiots, doesn't mean that the children of them should suffer for it.

    RFK Jr. plans to curb antidepressants, which he falsely compares to heroin

    Or if they are, be more frank about it. I appreciate that media has been getting more frank about "X administration official made the false claim" or "Y administration official said Z was never said. However they said Z yesterday. On tape". But, yeah, can we just start saying "drug addict...

    RFK Jr. plans to curb antidepressants, which he falsely compares to heroin

    The thing I find sickly ironic is, the man DOES have experience with one of the things he is comparing, but not the one most of us have experience with (SSRIs). Can he really say they are equivalent if he has only tried one of them?

    OpenAI president explains to jury why his diary entries sound greedy

    Lol. I am reminded of something a friend told me. In a custody dispute, she entered a letter her ex had sent to his employer (that lead to his termination). He claimed to not have it when asked by the judge. Her lawyer happily did and waved it up "oh, we do your honor. Would you like to read...
