What’s your favorite interesting fact?
  • Most electric cars only have 1 gear and it's always engaged. If you put the car in reverse, it uses the same gear, but the motor spins the other way.

    Even in neutral the motor still spins when the wheels are turned, it just doesn't output any power to the wheels.

  • Can video games help manage climate anxiety? 🎮
  • There is a difference between climate concern, where you desperately want to do anything to fix the climate problems, and climate anxiety, where you are so overwhelmed by the climate issues that it interferes with your ability to take any action.

    I suspect this study is focusing only on the latter.

  • What happens to very cold but unused batteries?
  • It depends on a lot of factors including the battery chemistry.

    NMC (Lithium ion) batteries are common in high performance cars and older EVs. They should be kept between 20% and 80% charge for normal use. 60% is ideal for storage, but anywhere in that range will do.

    LFP (Lithium ion) batteries are common in cheaper and newer EVs. They don't have a problem with being stored at 100%, and do have issues with not being regularly charged to 100% (monitoring gets less accurate over time until fully charged again), so leaving it at 100% is fine.

    Lead acid (particularly calcium) batteries get damaged when discharged too much, so it's fairly important to keep them topped up. If you are leaving the car for a long time, it could be worthwhile to connect a trickle charger to the 12V battery to prevent the car's computer from gradually draining the battery. Some cars will top up the 12V battery from the high voltage battery if left for a while, so this may not be needed.

    While I have little experience with low temperatures, I suspect that the car will be fine if left as stated above. The battery shouldn't get damaged by low temperature storage, and shouldn't lose much charge over time. Just don't expect full performance immediately after returning to it.

  • Variable Position Damper Control
  • Be aware that an underpowered or stuck stepper motor can "skip", causing the position data to be incorrect.

    A servo motor has active feedback, so doesn't have this issue. Servos do have their own drawbacks too, so they are not always a suitable replacement.

  • Games that force you to make hard choices
  • Prey gives you the choices up front, tells you they don't matter, then gives you a really good game to play.

    plot twist

    The way you play is entirely up to you, but that's the point. Are you who you say you are? It's easy to say whether you'll flip a switch or push a person when you're answering questions at a desk, but it's suddenly much harder when you're actually faced with the problem. What will you choose?

  • I'm so frustrated rn.
  • You can always try Linux risk free in a virtual machine like VirtualBox.

    If you like what you see, and you have any valuable data backed-up, you can try dual booting. That way you get to use Linux as your primary operating system, but can switch back and forth as much as needed.

    I found I was dual booting Windows and Linux for over 3 years before I was comfortable enough to stop using Windows entirely. Switching to Linux doesn't have to be an all-or-nothing approach. You can take it as slow as you want.

  • Having surgery on the 15th. Could use some reassurance if that's okay?
  • The surgeons handle this regularly, it's routine for them. You get to relax and let them manage everything.

    I went through lung surgery a few years ago and coped by deciding that I could trust the surgeons (and other medical professionals) completely. They know what they are doing, and they have procedures in place to make sure everything goes well.

    Learning to consciously relax and trust everyone around you is a something that takes constant effort, but in my opinion, it's worth it.

    My surgery went well, no complications, and my recovery was exactly on schedule.

  • Anyone drive? How do you find it? I am absolutely terrified after my first lesson
  • An SUV is very different from a compact car. Small cars tend to have better visibility and maneuverability, and are just easier to drive. If it's with your budget, an electric car is also easier to drive (and cheaper overall) because you don't have to worry about gears.

    The first few lessons will be overwhelming, particularly with stickshift. As you practice, you'll start doing more things without thinking, like when you put your foot down while stopping on a bike. I bet you haven't thought about that for a few years.

    Just take it slow, and trust that the instructor will not push you beyond your limits. After a few months/years you'll wonder why you thought driving was even difficult.

    If it were a reasonable option, I'd pick the train every time.

    What could be wrong with me?
  • If you are worried, a qualified medical practitioner is always more reliable than a web forum.

    Insufficient or poor quality sleep can cause problems with attention and memory, and can exacerbate existing conditions.

    Poor sleep could be caused by a medical condition (sleep apnoea), or psychological (stress). Often stress can be hard to identify, particularly if it's long term stress.

    Again, this might not be your problem, and finding the right doctor who actually listens to you is important. Don't be afraid to try more than 1 doctor if the first makes you uncomfortable.

  • Electricity Maps
  • South Australia has a huge amount of solar and wind, but relativity little storage, and basically no renewable base load (hydro, geothermal, nuclear). While the average renewable energy usage is fairly high, the instantaneous renewable usage can drop to almost 0 some days.

    Solutions are being implemented, and the renewable mix is gradually improving.

    Headache log

    I've been logging my headaches since I started taking Eletriptan in 2020.

    I've had an average of 10 days per month with headaches, and 4 days per month with migraines.

    So far I've identified stress and insufficient sleep as contributing factors.

    Not seeing a federated community's posts (solved)

    As far as I'm aware, these 2 communities should be kept identical by federation. The first link shows 4 posts, but the second link shows 0 posts. What could be done to fix this?
