Ask Electronics@discuss.tchncs.de•Lenovo USB-C PSU for laptops powers a Rasberry Pi, but cannot simply charge bicycle lights. WTF?English
4·6 days agoYour right, but it only needs a tiny amount to signal 5V.
The power brick engineers can choose to fail safe (just 5V only minimal amperage), or fail dangerous (5W power delivery) - for this lenovo power brick they decided to fail safe.

2·6 days agoThe spec is very clear, the source does not need to provide any amperage, just voltage. PE_SRC_Disabled (see my other comment in this thread)

Ask Electronics@discuss.tchncs.de•Lenovo USB-C PSU for laptops powers a Rasberry Pi, but cannot simply charge bicycle lights. WTF?English
7·6 days agoYeah, but some power bricks want to be safe and wont give any power without power delivery negotiation. It’s not unreasonable, and it is safe, it wont burn anything out.

28·6 days agoWelcome to the wonderful world of power delivery negotiations.
Basically your bike lights are too dumb to tell the power brick what they need. Use a cheap charger that will just send out the default without negotiation
Here is a 40MiB zipfile if you want the nitty gritty details: https://www.usb.org/document-library/usb-power-delivery

You are ending up in the PE_SRC_Disabled state on the source power delivery state machine.

Today I Learned@lemmy.world•TIL aphrodisiacs do increase blood flow to parts of your body but only those with compromised circulation will likely see any affects.English
10·13 days agoOnly people with compromised circulation? Last I checked only 96% of westerners have compromised metabolic health.
So this article is saying for 4% of the population aphrodisiacs are ineffective. Ha

Friendly Carnivore@discuss.online•Carnivore does not cure cancerEnglish
2·29 days agoDoing some other reading I do see the anti-parasitics having a beneficial impact on fighting cancer. It appears the mechanism of action is interference with cellular pyruvate function, which reduces the cells ability to metabolize glucose, slowing down the rate of growth. This doesn’t mean that cancer is a parasite, just that the drugs impact cellular metabolism in a way that demonstrates the warburg hypothesis (i.e. how pet scans work).

science@lemmy.world•Intermittent fasting no better than typical weight loss diets, study findsEnglish
12·29 days agoSure, but keto says it totally fine to eat a steak and a stick of butter and nothing else. That doesn’t seem sustainable.
Yet it is, we only need to look at the documented human populations that only had access to animal food before westernization. They sustained, even thrived.
Also I’ve never met anyone that does keto that allows any carbs.
Keto is just metabolic ketosis, any biological state while the body is producing detectable levels of blood ketones. Anyone can achieve it <20g carbs per day, and many people have higher tolerances (age, muscle mass, resting metabolic rate etc).
Just trying to offer insight into the down votes. I don’t think it’s the IF crew doing it. It’s probably people who are anti-keto.
Which includes you… https://lemvotes.org/comment/sh.itjust.works/comment/23819049

science@lemmy.world•Intermittent fasting no better than typical weight loss diets, study findsEnglish
1·29 days agoKeto (the actual dietary principle) is just based on a different distribution of macronutrients when achieving your caloric deficit.
Keto is any diet that maintains the metabolic state of ketosis. This can be done with overfeeding, underfeeding, fasting… and doesn’t even require complete nutrition (though that is always a good idea).

1·29 days agoYou need fiber, friend. You. Need. Fiber.
Citation please. As far as I’ve read fibre does two things:
-
Anti-nutrient, when people eat terrible food fibre blunts it so it isn’t as terrible by preventing some of the bad food absorption
-
Fibre is digested by the gut into short-chain fatty acids (SCA / BHB) which get absorbed through the gut, and has a boost to health in the area of absorption. However, in a ketogenic context the liver is making Ketones (BHB) all the time which gets deposited into the blood stream being available to the entire body including the gut… so this benefit is only seen in a carbohydrate metabolism, and not in keto.

science@lemmy.world•Six cancers rising faster in younger adults than older ones, study findsEnglish
3·29 days agoSince your waiting on the follow-up it might still be helpful to learn about the mitochondrial model of cancer.
It doesn’t hurt to go zero/very low carb while waiting for your results, then there isn’t extra glucose to feed any stray cancer cells floating around.

My car doesn’t have a internet connection, so any threat they make from the internet doesn’t seem credible to me.
