  • I’ve had that happen with what i assume was a hand lotion because there was a particular part of the lid that smelled.

    I don’t know why other people are treating you with so much disbelief. This absolutely can happen with people not thinking about how their habits impact what customers are consuming. With how many millions of coffee beverages that are served every day, it shouldn’t surprise anyone that some small portion are handled improperly with poor hygiene. It also shouldn’t be overly surprising if you’ve had it happen multiple times because you likely visit the shops near you. Such an event isn’t random and is the result of someone’s bad habits.


  • 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.







  • 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.
