  • I don’t understand why people like Facebook marketplace. It’s so transparently a way for them to just gather more shopping habits data on you, and it’s too easy for scammers to use. They act like having an account somehow makes it harder to scam.

    I would much rather support the website run by a skeleton crew that has no unnecessary features than get a few bucks more on FB marketplace. If I’m selling something that I’ve used, it’s cause I want to get rid of it, anyway.








  • Thanks for looking through all of this. If I’m understanding right, it seems like Congress is asking NHTSA to do a task that is probably not possible, but they are required to at least go through the motions to try?

    It seems like they just told nhtsa to use technology to fix drunk driving so they can wash their hands of the situation and claim they tried to do something, but nhtsa couldn’t figure it out. Why didn’t they tell the NIH to eliminate the cancer while they were at it.

    I do believe the technology to detect BAC is too erroneous to inflict on innocent drivers, and technology that could detect impairment through driving characteristics, while possible for individual drivers could never work on a population level. There’s going to be a lot of overlap between impaired drivers and just naturally bad drivers.


  • Im not 100% sure how the batteries are constructed from all of the cells (and I know it depends on the model), but the re-using process can work a lot better than just pulling out the battery and popping it down. EV batteries are in the range of hundreds of volts, but the cells themselves are about 4 volts. It’s my understanding that the battery as a whole doesn’t uniformly degrade, but you might have individual cells that degrade. If 1 cell in a chain of 10 goes bad, that chain can be made off limits to the battery, so you still technically have 9/10 cells that work fine.

    The way a lot of people reuse/recycle/refurb (not sure what the right terminology is in this instance) EV batteries is to test each of the cells themselves, and get rid of the duds, and keep the decent cells. Tesla, for example, all used to use 18650 cells (and I think some models still do), which is the same exact cell that’s in decent name-brand cordless power tools.

    When you aren’t required to keep weight, space, and extra circuitry to a minimum, you can really design a system that squeezes every last drop of usefulness out of those cells before they need to be melted down and remade.


  • The thing they don’t mention when they say that a combination of food items are “nutritionally complete”, is what quantities they need to be consumed in. Some micronutrients are technically in a lot of foods, but you’d have to eat the equivalent of 15,000 calories a day to get what you need. There’s definitely a lot of people around the globe who get by on rice and beans for 90% of their diet, but they do have to eat other stuff. Lots of nutrient deficiencies also take a while to start to have an effect, and the effects might not be obvious. I know what pellagra, scurvy, and rickets do, but I have no clue what a selenium deficiency would do
