  • Utah first state to hold websites liable for users who mask their location with VPNs — law goes into effect, designed to prevent bypassing age checks

    Jump

  • Big websites will only have to do it for a little while though, a month perhaps. If suddenly Utah can't reach youtube or Netflix... Constituents will complain, the citizens simply won't have it, and then the legislators have a problem.

  • Is Tatooine the norm? Planets may prefer living with two suns instead of one

    Jump

  • For many planets in binary or trinary systems, the two stars are so far away from each other, the people living on the planet might not even realize they're in a multi-star system. In these cases only one star would radiate meaningful amounts of light and heat.

  • New lithium-plasma engine passes key Mars propulsion test

    Jump

  • The thumbnail shows a hall effect thruster, highly efficient, very low thrust. Plasma thrusters are supposedly a very different beast. Plasma thrusters lay somewhere between the Hall effect ion thrusters and chemical rockets in efficiency, but with variable thrust, so they can do constant thrust like ion thrusters, or can scale up to high thrust like a chemical rocket (but would require a massive amount of power for that).

  • A giant pit in Switzerland will soon house the world's most powerful redox flow battery

    Jump

  • If this is some sort of hybrid battery that could be possible... Super capacitors take the initial charge, pass it on to the flow battery. But as far as I know, absorbing or releasing a lot of energy quickly is just not what flow batteries do, it's their biggest limitation.

  • US Navy warship loses power and propulsion after ‘electrical malfunction’

    Jump

  • This isn't really newsworthy. An incident occurred, they dealt with it appropriately, and things are running again now.

    This sounds like a Friday.

  • What game do you personally have the most hours played in?

    Jump

  • My answer will likely always be World of Warcraft. I played in my 20s and I played a lot. At some point when I typed /played, the number I got back exceed 1 year of in game time. I vowed never to look again out of shame. I this day I do not know what my total play time is.

  • Japan Is Building Cardboard Suicide Drones

    Jump

  • It only needs to fly once. Honestly, it'd probably work.

    But hey, I'm sure it's all irrelevant, I mean who would ever want to vindictively drone strike Seattle...

  • Supreme Court rejects bid to punish school for respecting trans student’s identity

    Jump

  • I just want to chime in here, I'm a bit disappointed to see the number of downvotes on this comment. Nomad isn't missing the point here, they're not saying anything insensitive or unreasonable. They're just saying that they do expect schools to be in touch with parents.

    Personally I don't know what I'd do if my child's school wasn't as communicative and supportive as they are, because my child certainly isn't. I truly rely on the school to know what's up with my kid.

    That said, I did read KryptonianCodeMonkey's excellent post as well, and it does clarify some important points and address additional nuance on the schools actual role. But if you read it, you'll notice that it also doesn't actually contradict anything Nomad said, it's just expanding on ideas, providing context and pointing out limitations and exceptions. All of that is great and super valuable, but it's crazy to upvote that and downvote Nomad's post.

    To sum up, this is bothering me because the negative score suggests there's something wrong with that post, but there's really nothing wrong with that post.

  • xkcd #3239: Simple Machines

    Jump

  • It's hard to decide which simple machine system to invest in. DeWalt makes a great lever and inclined plane, but I hear Milwaukee's wheel-and-axles are really good.

    I think Randall really gets my life.

  • xkcd #3239: Simple Machines

    Jump

  • Amazing

  • xkcd #3238: Soniferous Aether

    Jump

  • That's fair. Nearly everything at that scale is up for interpretation. I find that nothing in physics works the way it intuitively seems like it should.

    Jump

  • Get it just right, and yeah, lower latency. It's not likely to change the bandwidth though. 😉

  • xkcd #3238: Soniferous Aether

  • "refractive index”

    Not to split hairs here, but that's also kind of the same thing.

    Like what does "refractive" mean? Does it mean moving slower or bouncing around?

  • xkcd #3238: Soniferous Aether

    Jump

  • Exactly, at least that's my understanding!

  • This insect was trapped alive for 30,000,000 Years

    Jump

  • Many fossils are remarkably affordable, if that's your thing. I've seriously considered buying a megalodon tooth.

    You still need to be the kind of person who can spend a few thousand on something largely decorative or of novelty value. But hey, some people buy custom forged battle-ready swords, and some buy designer purses, so you know, whatever.

  • xkcd #3238: Soniferous Aether

    Jump

  • That is not the speed of light through fiber. That is the speed of light bouncing at diagonal angles as it travels through fiber.

    It appears to travel slower because it's not traveling in a straight line. But I promise, every individual photon is traveling at exactly c. Photons emmited simultaneously will not all arrive at a destination at the same time, but this isn't because they're traveling at different speeds, it's because they're taking different paths, reflecting and refracting slightly differently.

  • It's an awesome comment, it totally could have been the hover text.

  • Excited to announce our Steam Controller arrives on Steam May 4th at 10 a.m. PT. | Valve via Bluesky

    Jump

  • It's crazy, I haven't bought a console in a while, so I've actually never spent more than $50 on a single controller. That said, I already think I'm going to buy this.

    I was really impressed when I used a steam controller at pax years ago, but didn't end up pulling the trigger, my usb Xbox controller was good enough. But that controller has some significant stick drift now, and I have had situations where I really wished it was wireless.

    Honestly, I just have a good feeling about this device. I don't know if it'll be as reliable as items like my Logitech mouse for instance, but I'm hoping it lives up to that.

  • JWST Hunts for an 'Earth-Moon' Twin in a Habitable Zone, But the Star Has Other Plans

  • I'm really glad this story ends with a silver lining. I'd say that it's a near certainty that they've successfully collected the data they needed. Over time our tools for analysis only get better. Sometimes we sit on data for years before we develop the ability to properly analyze it, but we get there.
