    The company does not explicitly state what wavelength they are using, but I’m guessing it’s very large. They state on their website that their goal is a receiver on earth that is about 5km in diameter. This would suggest they are using an incredibly long wavelength for power transmission.

    Long wavelength radiation is able to pass through small objects without interacting with them. You can stand next to a 50kW AM radio station tower and feel nothing at all. The long wavelengths used by AM stations pass through humans easily without interacting with us. A 50kW microwave emitter right next to a human would basically explode them because microwaves are a small enough wavelength to interact with water.

    Even if this company was sending terawatts of power, a large enough wavelength would let it pass through clouds and people with no interference.

    EDIT: Fun fact, we do use short wavelengths to transmit data because they are able to hold more information than longer wavelengths. 2.4Ghz WiFi is just about the same as what your microwave uses to cook food. WiFi transmitters are just so low power and unfocused that the amount of heating they do to our bodies is imperceptible.

    You may notice your phone’s WiFi signal decreasing if you stand next to a running microwave. The small amount of radiation that leaks from your microwave is enough to overpower the signal from your router, but still unnoticeable to our bodies.

    I found this post that has a solution for this. You can set an external keyboard or mouse to wake up your laptop from sleep. As long as you don’t shut your laptop down, you wouldn’t have to open the lid to press the power button.

    Edit: Also apparently there is something called wake on LAN that you can configure. It would allow you to use another device on your network to wake up your laptop if that’s a better solution than moving the mouse or pressing a key on the keyboard.

    Have you ever considered a motorcycle or scooter?

    A state approved training course, full high quality safety gear, insurance, and a used bike can all be had for under $5k. If you want to go for a new bike, you can still be all in for under $10k.

    I got a 125cc scooter for $1.5k and it’s not incredibly fast, but it’s much more engaging in corners than a car has ever been.

    EDIT: Just saw your reply to Plik and definitely valid. It’s not for everyone and it’s best to know your limits.

    My only trackpad complaint is that sometimes I’m trying to use the trackpad to copy a large body of text and I run out of trackpad before I can select what I want.

    On many applications I can just click with one finger and use another to move the cursor, but some applications require the finger that clicks to also move the cursor.

    Oh yeah I think all kinds of CSAM is immoral even if it’s a drawing or AI generated. I’m not trying to say that there’s some scenario where CSAM is acceptable.

    I also don’t even know if AI CSAM decreases the demand for real CSAM, so my theory may be completely wrong. I am just wondering if AI CSAM can lead to less bad outcomes for real children.

    As a summary for people who didn’t click the link, there are apparently many users using the AI to create CSAM role play scenarios.

    I have not read any research on this, but does using AI to create CSAM reduce the market for real CSAM? Does AI CSAM actually protect children by reducing the demand for real CSAM?

    Ideally, there would be no CSAM, but even with cultural taboos and many laws against it, people still make it. Is this an effective form of harm reduction?

    I’m a left handed writer who does many other things right handed. My recommendation is to not rush out and buy a bunch of left handed items for your son.

    Present the standard right handed version of things to your son, but let him use it in the way that is most comfortable to him. If he really can’t find a comfortable way to use some object, go and buy the left handed version, but don’t jump straight to the leftie version.

    The world is designed for right handed people in ways that is not apparent unless you are left handed. The world generally does not accommodate left handedness, so lefties have to adapt to a right handed world. If you teach only on left handed objects, your son will one day be in a situation where he has to use a tool designed for righties and struggle much more than he needs to.

    I had this journey a while ago and landed on a Janome HD-1000 or HD-3000. It’s a simple but robust machine with a strong motor that can handle heavier fabrics.

    Beware of the machines that have dozens of different stitches. In general, if a machine is prioritizing adding in stitches, it’s cutting corners in other places. You really only need a few stitch types to do everything you need to do. If you want to do more ornamental stitches or serging, a dedicated machine will be preferred over a jack of all trades machine.

    My dog also has some separation anxiety that you seem to be describing. I have him on Prozac that the vet prescribed for him that helps him a ton. It’s only $15 a month for his prescription but got him 50% of the way to being better for me.

    I paid $2500 for dog training that has really solved all his negative behaviors, but I get that it’s a sacrifice to pay that much.

    Look into the medication with a veterinarian, but I would start saving ASAP for a trainer if it’s possible for you to put any amount away.

    I personally think that a lot of people have a skewed idea of what people are supposed to look like due to higher rates of overweight and obese people. You probably look just fine. If you feel good and are strong, what does it really matter.

    If you are scared of gaining too much fat, you can just bulk really slowly with a slight calorie surplus. You’ll gain mass slower, but you will gain less fat than a high calorie surplus bulk.

    The bigger problem with sideshows is that there are often guns, drugs, and alcohol present. People usually get hurt.

    Edit: I also wonder what effect the feeling of lawlessness has on the community. If someone can break the rules in a large public manner, does that reduce others’ feelings of obligation to act in ways that benefit the community?
