Learn to dance
Where? How? I’m interested, but lack knowledge so very thoroughly that I don’t know what to Google or how to judge the results of a best-guess Google search beyond “bellydancing is not for me… probably.”
I take it the requisite level of mathematical maturity is fairly low? (For instance, I’m assuming Rosen doesn’t leave gaps in his proofs for the reader to fill in.)
I ask because I’ve sometimes had trouble with low-maturity math books with novel content, and “accessible” can mean “little mathematical maturity required” or “high-school-level prerequisites”.
This discussion has already happened at great length here.
To summarize my stance: there’s risks, but considering that everyone I’ve read on discourse.soylent.me has had positive results across the board, from body composition to semen taste. I get noticeably improved mental clarity (along with getting so lean I’d be scared I was undereating if I didn’t know precisely how many calories I was eating and clearer skin), which makes me willing to accept those risks. Also, because soylent might be safe and come with a load of benefits, there’s data-generating value in taking individual components, blending, and pouring them down my throat to see if anything bad happens. (Julia Galef on tradition as it pertains to social systems, that happens to be applicable here.)
But I’m not very worried; I have trouble imagining a food that has positive effects of “improve body comp, improve mental clarity, clear skin, make semen taste good” and no known negative effects and is biochemically plausible to actually be bad in the long term. Certainly not impossible, but not very probable, I think.
Lindeberg is a nutrition researcher (conducts studies, co-authors papers) coming from a medical background, which makes him just as much an expert as a nutrition researcher coming from a biochemistry background.
Why wouldn’t nutrition scientists studying nutrition come to a similar conclusion about how young, murky, and complicated nutrition is and only make very conservative, very strongly supported recommendations?
We can measure how much a field has progressed by its predictive power, and nutrition is already making concrete predictions with high confidence. Not a lot, not with the confidence of, say, Newtonian mechanics but, given how very much literature there is and how very complicated things are, the level of consensus across researchers who are coming at the problem from disparate-but-legitimate approaches (e.g. biochemical, evolutionary) is sufficiently impressive that I do trust them to judge the literature properly. Humans are biased, so it’s unsurprising that we don’t yet have a consensus as broad as, say, existence of the golgi apparatus, but the world looks exactly as we’d expect it if nutrition scientists were doing good work in a complicated field.
To summarize: Lindeberg, like Campbell, is an experienced nutrition researcher with impressive and relevant credentials. Nutrition is a young and complex field, so there’s no broad consensus about everything—although there is broad consensus about some things—but nutrition scientists are doing a decent enough job of figuring things out that I trust them to judge the literature properly.
Read recent academic textbooks
Any recommendations?
The selective pressure on being able to digest lactose as an adult is stronger than the selective pressure to not develop heart disease from eating too much meat, since the former kills you before you can reproduce. Lindeberg claims that humans have sufficiently recent common ancestry that, in absence of the kill-you-before-you-reach-childbearing-age selective pressures, we’re able to generalize from group-to-group fairly well. Non-Inuit probably do worse than Inuit on Inuit diets, and bool is_Inuit is a useful input in a program to produce an optimal soylent blend for someone, but the selective pressure isn’t strong enough for the Inuit to be mostly devoid of heart disease [1] simply because it was selected for.
Also, many other hunter-gatherers from all over eat large amounts of meat (though as much as the Inuit) and are just as devoid of Western disease as are the Kitavans, who consume relatively little, which supports the hypothesis that Inuit aren’t mostly devoid of heart disease because they’re genetically unusual.
[1] IIRC Inuit do suffer from slightly more Western disease than Kitavans (most calories from plants), but not by a very impressive margin.
I’ve been watching for several years now (I adopted the diet myself in 2010), and all of the negative critiques tend to fall into (a) critiques from non-experts, (b) critiques from experts in unrelated fields, (c) health experts who agree that his recommendations have merit, but that they’re impractical for the general public to follow.
I produce for you a book written by a relevant expert with ~2.5 times as many references as The China Study (2034 vs 758) who advocates eating an ancestral diet (lean unprocessed meat/fish, fruit, nuts, vegetables/root vegatables) (1). A list of individuals with relevant graduate degrees who more-or-less agree with him can be found in this list of speakers at a paleo conference he spoke at. His recommendations are at least as similar to the recommendations the Mayo clinic returned for me as Campbell’s.
That is, I can make a symmetrical argument for a significantly different diet (2), complete with experts and evidence and stuff.
So, to address your questions directly: you should believe that nutrition is a young and complex field, and therefore shouldn’t have everything all figured out; my take is that you may do well to replace grains with root vegetables, since that’s something everyone agrees is good (plus they’re really tasty!); this isn’t good enough to inform your dietary choices because I just used a symmetrical argument for a diet that has nonnegligible discrepancies with the diet Campbell recommends; and I don’t know how to dig out a signal that experts, to my knowledge, haven’t managed to dig out without becoming an expert.
(FWIW, I spent about 5 years as a vegetarian, followed by 1.5 years doing the paleo thing, and now subsist entirely off DIY soylent, which combines the virtues of deriving all its protein from animal sources and being processed.)
(1) Interestingly, Campbell’s and Lindeberg’s diets can be eaten simultaneously, and this intersection is 100% in-line with what the Mayo clinic recommended me. The difference is that Campbell allows grains and beans, and Lindeberg allows (unprocessed) lean meats, fish, and eggs.
(2) Again, there’s substantial overlap, but also substantial disagreement: Lindeberg, for instance, observe the Inuit derive something like 98% of their calories from animal sources and are virtually untouched by Western disease, and concludes that very high consumption of (unprocessed) animals is perfectly fine, whereas Campbell claims that humans should eat minimal amounts of animal.
This is a wonderful data point. It moves our model from “if you’re a man, don’t wear makeup” to “if you’re a man, don’t wear makeup unless you’re going to appear on camera, in which case, wear just enough to counteract visual artifacts.” I expect this to be a nontrivially better model for a significant amount of men here.
Any data on whether women prefer men with light makeup?
I’m given to understand that the print and audio versions are being held off until readers of the eBook root out the last of the errata. Where should I submit any I find?
It occurs to me that, given the philosopher’s stone is around, any superweapons Harry could create and conceal with it in slightly under an hour could exist in the clearing, provided that they’re enough to let Harry survive another hour, access the time turner, and create said superweapons.
Also, since prophecies are self-fulfilling and Voldemort prefers a world that won’t end to a world that will and Harry has already made the appropriate unbreakable vow to do everything to prevent the end of the world, Harry could argue that expected universe where Voldemort lets Harry live is far superior to the one where Harry dies.
I’m assuming quaffles are still worth 10?
What are some sensible-sounding alternatives to eliminating the snitch entirely?
The best I can think of is have two snitches—red snitch, blue snitch. Whenever a seeker catches their snitch, the opposing team can’t score any more; the game ends when the second snitch is caught.
I believe that the people who attribute criticism #2 to feminism believe that feminists conflate “story about abuse” with “story encouraging abuse.” If feminists are indeed doing this (I’m unsure whether they are), then criticism #2 ought to be attributed to feminism; the general population seems to have no problem with stories that portray unacceptable-in-reality sex (for instance, “NonConsent/Reluctance” is a major story tag on Literotica.)

Salem Witches’ Institute or a dojo in Asia seem the obvious choices, so we can probably safely eliminate them (because when was the last time EY used the obvious solution in MOR?)
Do we actually disagree about anything?
We certainly agree that the Barracuda’s are crap in NAS’s. I believe that WD Red’s are a major improvement and Hitachi Deskstars a further improvement, which is just reading the Backblaze data (which is eminently applicable to NAS environments), so I’m we’re in complete agreement that, for NAS’s, Barracuda << Red < 7K2000.
However, I also contend that, in a desktop PC, a lot of what makes the Reds and 7K2000 more reliable (e.g. superior vibration resistance) will count for very little, so they’ll still fail less often, just not 1/40th as much. Even if they’re four times as reliable, moving from, say, a 4% annual failure rate vs a 1% annual failure rate may not be worth the price premium (using Newegg pricing, the Hitachi drive costs 72.5% more, but on Amazon, the Hitachi drive is cheaper. Yay Hitachi?), especially since RAID 1 is a thing (which would give us a 0.16% annual failure rate at a 100% price premium). Obviously, if you can find higher-quality drives for less than lower-quality drives, use those. But, in what we’d naively expect to be the normal case, if you’re paying for features that drastically reduce failure rates in NAS environments, but using your drives in a desktop environment where these features are doing little to extend your drive life, then you’re probably better off using RAID 1.
(Why do I use low single-digit annual failure rates? Because I remember Linus of Linus Tech Tips, who worked as a product manager at NCIX and therefore is privy to RMA and warranty rates, implied that’s about right. He produces a metric shit-ton of content, though, so there’s no way I’m going to dig it up.)
I’m also interested why you’re dismissive of AnandTech. I currently believe they’re gold standard of tech reviews, but if they’re not as reputable as I believe they are, I would very much like to stop believing they are.
My above comment was poorly written. Sorry. Hem.
Consumer-grade HDD’s, used properly, all have about same, low failure rate. If you treat your desktop like a NAS or server, they will drop like flies (as evidenced). If you treat your desktop like a desktop, then a lot of the price-raising enterprise-grade features (vibration resistance, 24⁄7 operation) count for zilch. They’re still higher-end drives, and will last longer, but assuming you give your desktop a fraction of the maintenance you give your car (like, take 5 minutes to blow it out every other year), not a lot.
Assumption not in evidence.
Mea culpa. I’ll give you heat, but vibration tolerance and 24⁄7 operation are enterprise-grade features with minimal relevance to desktop hard drives. Evidence. Evidence. Why I’m inclined to distrust anything Backblaze publishes + evidence.
tl;dr Looking at this data and concluding “avoid Seagate Barracuda drives” is a bit like noticing that bikers survive accidents more often when they’re wearing a helmet and then issuing a blanket recommendation to a population primarily of car-drivers to wear bike helmets. Sure, it’ll reduce your expecting mortality when you go out for a drive, but not nearly as much as you’d expect from the biking numbers.
