I imagine sel4 could be possible, but I haven't done any specific checking for compatibility.
Current draw - depends on the operating mode, etc. A dabao board with all its regulators and overhead draws around 30mA @ 5V. The CPU in "WFI sleep" (clocked stopped, instant wake-up, all memory preserved) will draw about 12mA @ 0.85V. There's a "deep sleep" mode that requires an effective reboot (clock stopped, no memory preserved) to come out of where it's down to under 1mA @ 0.7V. These latter low power modes require an external power management architecture that can vary the voltage of the core so you can achieve lower leakage states.
I think comparatively speaking, the Baochip doesn't have strong low power numbers. I have always imagined it as more of a chip that gets stuck into a USB device, so it's plugged into a host with a fairly ample power reserve, and not a coin cell battery.
I actually noticed this as a kid. One of the early GTA games north locked minimaps, and I knew the city well. Later ones did not, and I was always more confused.
I've pretty much always had GPS nav locked to North-Up because of this experience.
Pandoc? It might help you. If you are programatically generating content, you can emit the JSON intermediate format. If you are hand writing, you can use something more sane like djot.
PDCAAS is dumb when looking at multiple foods. E.g., beans and rice, when consumed together, are like, 0.99, depending on the ratio. That is, the sum is greater than the parts.
Adding rice might get you close to that for the amount of rice you eat, but 1 cup of beans will get you 16g of protein and 1 cup of rice will get you 4g of protein.
So a chunk of your protein intake would still be incomplete. It's not like the ratios are perfect so that a cup of each gets you 20g of PDCAAS 1.0 protein. Doing some quick napkin math looking at the AA makeup and protein digestibility of the two, it's like 14g equivalent of PDCAAS 1.0 protein.
~25% is a pretty significant gap if you're trying to hit optimal levels for things like muscle growth, etc.
From what you just wrote, it appears you misunderstood what I said. Just to be clear:
Red kidney beans (50g): PDCAAS = 0.88, Protein = 11.25g
Basmati rice (50g): PDCAAS = 0.7, Protein = 4.5g
Red beans + rice (50g, 50g): PDCAAS = 1.0, Protein = 15.75g
Milk (500g..): PDCAAS = 1.0, Protein = 15.5g
So, from a protein perspective (according to PDCAAS), 500g of milk will give you the same amount of usable protein as the 100g rice and beans meal. There is nothing left on the table.
So, just eating kidney beans, PDCAAS would say that you aren't really getting the full benefit of the "protein on the label". But once you combine it with rice, you are getting the full benefit (according to PDCAAS).
You can't look at the digestibility of the two foods in isolation to make the calculations.
As long as you are eating a varied diet, PDCAAS is pretty pointless. If you have an eating disorder, or food scarcity issues, then it might become important.
This is the things thar gets me the most. Code review is _hard_. So hard that I'm convinced my colleagues don't do it and just slap "LGTM" on everything.
We are trading "one writer, one reader" for "two readers", and it seems like a bad deal.
Yep, and I'll add: the first reader is the first maintainer. When that is turned over to an LLM agent the organization's leadership had better be prepared to entertain rewrites (reprompts?) of significant portions of LLM-generated code on a regular basis. The call of the rewrite isn't new of course, but it'll be far more alluring since LLMs are at their most "productive" and least destructive when working from a clean slate.
Not the poster, but, usually what people are referring to is all the other stuff that comes along.
Per calorie beef and broccoli are actually surprisingly similar, but broccoli comes with fiber, calcium and vitamin C, while beef comes with saturated fat.
Of course, broccoli is not very calorie dense, so you would need to eat a lot.
More realistically, tofu, which has about as much protein per calorie (and almost as much per gram) as middling lean beef. But has half the saturated fat, more iron, more calcium, and fibre.
You just get more good stuff, and less bad stuff with veg.
Bioavailabilty is a bit of a non-issue. It's measured as if the food you are measuring is the only food you eat. So if it is slightly low on one amino acid, the "bioavailabilty" drops, but noone eats like that. Once combined with other foods, the total "bioavailabilty" tends to increase.
Dietary cholestrol hasn't really been overturned, but sure there is some nuance. Some people do respond badly to dietary cholestrol (like you said, individual advice is sometimes required), but dietary cholestrol is also not a linear response afaiu. That is, if you eat one egg a day, you may as well eat 4, but if you can completely eliminate dietary cholestrol it could make a difference. So, many guidelines don't bother with suggesting it, because it's too hard to eleminate it to the point of mattering for the average person.
All that to say, the science isn't wrong, but the practicalities influence the advice.
The guidelines haven't changed, but they should be. The association between cholesterol and CVD is specifically related to blood cholesterol levels. However, in healthy individuals, blood cholesterol levels are not strongly impacted by dietary cholesterol choices - since cholesterol is synthesized in the body, there is homeostasis, and higher cholesterol intake leads to lower rate of synthesis, maintaining the same blood levels.
However, some individuals suffer from a bad regulation of this homeostasis, and for them dietary cholesterol does lead to persistent high levels of blood cholesterol as well. So the guidelines should apply for them, but not for everyone else.
I'm also curious about the current draw, but I couldn't find anything?
