I know it's possible So

How?

Sup nerds (jokes)

I have a shit load of yard waste mostly gravel and shitty soil and rebar that I need to get rid of. The local waste disposal place weighs my truck before and after I toss my shit but the last time I went there I paid like $50 for just a bit of stuff. I think they're jewing me or their scales are fucked.

I want to pay less so I was thinking how I can do this. Is there some kind of negative weight I can add to my truck and then take it off before the weigh out when I leave? Or can I hang a couple plates from the bottom of my truck and then put them in the truck bed before weighing out?

Help me nerds lol

If I feel beyond down all the time (what I suspect to be a depression but I don't want to take benzos..) is giving Seretonin supplements worth a try?

This isn't meant to be a 2edgy4u post, and I'm hoping this is the correct board for all this, but I really am at the point where I believe I have some sort of personality disorder. After doing some pretty bare bones research a few years back, I began to wonder if I had sociopathy. I talked to a therapist about this, and she claimed that people who have personality disorders typically don't know that anything is wrong, but at 24 years of age I really am just finding it impossible to believe there isn't something majorly wrong with me. For starters I
>almost certainly had conduct disorder as a child
I was suspended from school several times, on top of being arrested for truancy and drug possession at school multiple times. I was also a serial vandal and shoplifter, and had abused substances from an early age. I was also abusive to animals as a child.
>have had continued problems into adulthood
On top of abusing animals, I also have abused people as an adult. While I have not had any more runs in with the law, I have had trouble obeying the rules both in the military and in civilian jobs. I have been fired from several jobs for getting into altercations with customers, and have continued to abuse substances sporadically.
Again, if this is better served on a being on board such as /adv/ tell me, but I was hoping to garner a more science based perspective about all of this. Are there any psychology majors here that could help me out? Do I have a personality disorder or am I just a run of the mill piece of shit?

/sci/, how much colder does the sun get at night-time?

Did we actually domesticate dogs from wolves, or is this just a dogma that has survived for centuries? To me here, it seems like it's more likely that canids can all interbreed (they can) and we domesticated the local "wild dogs" and they are still literally "wild dogs". Where did the wild dogs come from?

brainlet here, I'm trying to go back through my old comp sci notes to learn shit I didn't really grasp in class. I'm re-learning about NP problems, and NP hardness.
I'm confused by wikipedia though. On NP-Hardness it says this:
>A decision problem H is NP-hard when for every problem L in NP, there is a polynomial-time many-one reduction from L to H.
But it also says this:
>NP-Hard:
>Class of problems which are at least as hard as the hardest problems in NP...

How are those not contradictions? As I understand it, if every problem in L is reducible to H that means H is equally or less complex than those problems in L. But the second thing says the opposite, that H is equally or more complex as all problems in L.

Artificial intelligence will never be able to compensate for a lack of human intelligence.

Bro's, am I like a plant or something? Isn't this called photosynthesis or something?

The antihistamine effects of tricyclic antidepressants are well-known and documented, but it's hard to find anything online on antidepressant effects of tricyclic antihistamines. Do they exist?
