  • Back during Apollo, they relit the lunar transfer stage engines in orbit, and just pointed it so it would escape earth and go into deep space.

    This also allowed them to have the stage fueled, without risking a giant explosion if it entered the atmosphere. Because the stage was already in a stable orbit, even if the engine didn’t light, all of the fuel would boil off before it entered the atmosphere.

    A suborbital flight would only allow a short term test, whereas the real HLS will be spending many days between relights. Plus, the ship will be entering the atmosphere with a substantial amount of fuel in the tanks, which just seems needlessly dangerous.

    ChatGPT is a tool that is used for cheating.

    The point of writing papers for school is to evaluate a person’s ability to convey information in writing.

    If you’re using a tool to generate large parts of the paper, the teacher is no longer evaluating you, they’re evaluating chatGPT. That’s dishonest in the student’s part, and circumventing the whole point of the assignment.






  • Lack of affordable housing is certainly an issue.

    When rent is over half of your budget, how do you keep a roof over your head when an emergency comes up.

    We need mental health care too, but we also need to correct the housing market in general. Building lots of cheap housing is still a good option.

    The new housing development near me is trying to sell brownstones for half a million, and the new condos are going for 250K. They’re all nearly empty because very few can afford them. So we either need higher wages, or actually affordable housing. Ideally we’d get both, it’s not like we don’t have the money to try multiple solutions.



  • The “front” or “forward” direction of a screw is clearly the face of the fastener itself, be it a hex head, Phillips, or Slotted screw. Picking a side of a face as the front doesn’t make any sense. The whole thing needs to rotate one direction or another, and it will either rotate to the right to tighten, or the left to loosen.

    If I ask you what the front of a clock is, are you going to tell me it’s the top curve near the ceiling? No it’s the face of the clock, and the hands rotate around it to the right.




  • What the fuck are you talking about.

    You’re either rotating the fastener to the right or the left.

    It doesn’t matter what side you’re talking about, because you’re not moving one side of the fastener, you’re rotating the whole thing one direction or the other.

    Clockwise just means something is rotating to the right.

    If I ask you to turn around to the right, are you going to ask me what side of you I’m referencing?
