  • No, never. Current charging rates already get close to thermal constraints. Hitting those charging rates either requires accepting much lower power density or using way more metal per cell. This research might inform design changes to improve charging rates, but we’ll never see high capacity batteries charging in a minute.

    The researchers know this and only mention wearables and iot devices applications. The article author erroneously makes the leap to high energy density devices.

    If you don’t care about energy density at all, ceramic capacitors can already charge and discharge in microseconds.




  • It does seem like something that could be worth just trying. I can’t imagine the seeds/nuts would cost much. So if you already have grow bags there’s not much to lose by experimenting with it.

    Do you have a balcony that gets some direct light? I tried balcony growing in a northwest facing apartment balcony. It was enough to keep some things alive, but not enough light to actually get much flowers or fruits. I definitely appreciate your frustration.

    That was one of our main motivations to buy a house tbh. So many plants never truly thrive in containers, and spending hundreds on grow lights to grow $10 worth of food is hard to justify.




  • Blowing up a solar system was destructive, yes, but only the one research assistant died in that one iirc. So I’m not sure if that event gives McKay the deadliest scientist crown.

    He did re-enable the attack directive of the replicators which led to countless human and wraith deaths.

    There’s also that time when McKay started ripping a hole in an alternate universe’s spacetime that would have destroyed an entire universe.

    Beckett’s contributions to the Hofman drug might make him deadlier than Carter.




  • Oh for sure. I do my best to avoid Amazon because most listings are full of made up lies. I know marketing is full of half truths and exaggerations, but I despise shopping at places that try so hard to deceive me.

    I just brought up Amazon since Amazon and monoprice are the most common options I see mentioned when people ask for alternatives to the overpriced options at best buy or whatever.

    Industrial suppliers can be more expensive, but the time and aggravation saved by shopping by specifications you can trust is frequently worth a modest price premium. I’ve switched to Digikey and McMaster for a number of personal purchases after realizing how much of a mental toll deceptive marketplaces carry.



  • This was pretty close to being true for 1080p and lower resolutions. If you get a 4k 120hz HDR display then bandwidth and signal integrity start becoming very important. The article you linked is rather old and really only considers media up to 4k 30fps. Cable quality especially matters at lengths above 4 ft for uhd and higher.

    There’s a lot of snake oil so you can’t just trust marketing claims. I’ve had terrible luck with cables that claim to support high resolutions from amazon and even monoprice. I’ve resorted to buying cables from actual electronics suppliers like digikey since their speed ratings should be accurate.





  • Two suggestions: run a humidifier. Preferably use a steam one with distilled water. The ultrasonic cool mist ones introduce any minerals and bacteria that are in the water into the air.

    The easiest suggestion is to change your blanket. I’m guessing you’re wrapping yourself in a fuzzy fleece blanket. Synthetic fibers like polyester transfer way more static charge than natural fibers. Try looking for a cotton or wool throw. Or for something fuzzy, find a sheep pelt with wool on it. Even using a cotton sheet between you and your current blanket should reduce the amount of charge buildup.

    A side benefit of changing blanket materials, is that any blanket that generates a lot of static charge also holds loads of dust and pet hairs. A less static generating blanket will stay cleaner longer.

    The easiest way to discharge is to touch a metal faucet. If you have copper pipes, they’ll be grounded, but even just the tap water is conductive enough to dissipate most of the charge.
