i was a pothead in high school, thats a big part of what attracted me to the sciences, i knew that there was important druggie information buried in there somewhere, getting at that and stealing a triple beam were both ambitions i achieved.
i learned a lot when we had drug education class, when they got to the part about pot they were teaching us about THC percentages and they told us regular pot had about 2%-5% THC, hash had about 10%-15% and hash oil had 30%-40%.
seeing that hash oil stat blew my mind, i'd gotten hash before and it was A+ high power stuff, so the possibility of something more than twice as good captured my imagination. eventually i learned how to make my own hash oil and educated myself about solvents and distilling in the process. i learned a lot that way and it was worth the effort because that hash oil was super strong, just like they promised in high school drug education class.

Is urine therapy legit?
Someone told me they used piss to help treat themselves
“ I’ve been chewing for 20 years. Few months back I was in big trouble. Enflamed bleeding gums, cavities, plaque, tooth infection with swelling in my cheek and a loose tooth. Pain that wasn’t awful, but bad enough where I couldn’t think about doing anything else. I undoubtedly needed at least a route canal.

Started fishing around for what to do and I had done urine therapy before for other issues. But did not know that it will help all oral issues.


Held my urine in my mouth 15 mins at a time 3 times a day. And my mouth was basically healed in a week. Tooth firmed up, pain gone, no bleeding or enflamed gums, etc.”

Just antiseptic mouthwash, you can get stronger ones from your dentist. You should only use it for like a week, just once a night after brushing and flossing. Pic related is what I use. Every few months I'll use it for a week. I used to dip for almost a decade, so I had a very intensive cleaning that took two appointments to finish, and after that I've been very meticulous about my oral hygeine.

There are likely some compounds in urine that have health benefits. The problems is they are in low concentration and mixed with things that have proven health non-benefits.

This shit saved my life. The problem nobody realizes with mental health is it isn’t in your head but stress and trauma stored in your body. This is why talk therapy and meds don’t work.

The guy behind TRE David bercelli figured out two things. One was, wild animals never have long lasting effects of stress and anxiety after getting attacked by predators because they instantly tremor out the stress and trauma. So a croc snaps at a zebra, zebra freaks and gets away, tremors, then goes back to grazing 1 min later like nothing ever happened. He also noticed that in 3rd world countries when in bomb shelters that after a bomb went off the kids would naturally shake, but the adults wouldn’t. Because we have all been conditioned to think shaking is weakness. So the kids would shake and end up fine and the adults wouldn’t and would go on to develop PTSD.

But we have a built in mechanism to tremor and shake to release all this pent up stress and trauma and reset our nervous systems. So all these cops, vets, and tendie eating anime jerking off NEETS who want to kill themselves just need to tremor and they’ll be fine.

All of 2019 I wanted to kill myself from derealization and depersonalization brought on by anxiety and stress because of thyroid issues. Then I found somatic experiencing and the overlapping TRE exercises. SE didn’t really work but the TRE was magic and fixed me

i'll share an anecdote.
i have a wonderful young terrier, wouldnt trade him for the world. everything i could dream to be and more.
>persitantly shakes during thunderstorms and storm activity, in the wild he'd "shake it off" and move on with life, however, due to traumas in the past (see LOUD NOISES) and seeing this behavior as a coping release he now shakes as a communicative effort to express to me of his discomfort or fear so i now provide the comforting. This is defeating the purpose of the system and has cause long term behavior changes for the worse. (still a good boy, just shakes when scared the poor thing, he doesnt know any better)

this is a fundamental misunderstanding of the fight or flight reflex and its intellectually dishonest to try and apply it so sympathetic nervous reactions to traumatic or life-threatening situations.

do what, adrendal loading? the vid was basically a sales pitch for the therapy.. what did you want a comment on..? as was the prior vid, with a little more explanation.

If you still want a real answer... God this board is a mess.

Assuming this is a simple MLP or simple Feed Forward, no drop out or skips or not an RNN. Nothing than would make it more complex.
Just take the power consumption (like via nvidia-smi if you are training via GPU), the training time and the number of total nodes and make a simple division.

>> No.12619134

But that would give an average distribution of the power consumption. Shouldn't there be a difference between layers?

Anyway even if you reduce the network with regularition,you still need to start with as large network aspossible.

>When potato tubers are exposed to light, they turn green and increase glycoalkaloid production. This is a natural defense to help prevent the uncovered tuber from being eaten. The green colour is from chlorophyll, and is itself harmless. However, it is an indication that increased level of solanine and chaconine may be present. In potato tubers, 30–80% of the solanine develops in and close to the skin, and some potato varieties have high levels of solanine.
>Home processing methods (boiling, cooking, frying) have small and variable effects on glycoalkaloids. For example, boiling potatoes reduces the ?-chaconine and ?-solanine levels by only 3.5% and 1.2% respectively, though microwaving causes a reduction by 15%. Deep-frying at 150 °C (302 °F) does not result in any measurable change
Wait, so when Arthur told me green sunburned potato chips are safe to eat they were actually lying??? What the fuck???

Boiling reduces a lot toxicity and to die you need to eat a huge amount of almost rotten potatoes.
So no, you don't die that easily.
Why would eat even a small one like that is beyond me though.

Oh, I didn't read that. That's why.
Well I guess your neighbors are not that friendly as you thought.

That's very interesting, thanks

Eating a single one like D.W. did won't kill you. But yeah, it's stupid to make children believe those are completely fine.

Boiling doesn't diminish solanine in a significant amount and the potato wasn't rotten, it was toxic for a different reason.
>eat even a small one like that
I'm used to bitter food. My mother was a terrible cook and she also believed in the properties of horribly bitter tea.

The potato LOOKED fine. They couldn't have known.

23 yo guy from a sperm bank. Was smart but sadly mentally ill living in a mentally ill inducing culture and society. Stopped taking his drugs and killed himself. Thought he lived in a simulation and no one was real.
