Given that HHS is now run by a nutcase, it’s surprisingly not a completely insane dietary recommendation. I think a sensible person would do OK following those general guidelines.
That said, if you don’t like it, disregard it. No one is forcing you. I think it has too much emphasis on protein but that’s just me.
These guidelines theoretically could influence school lunches. Will it make them worse or better or change nothing? ¯\_(ツ)_/¯
I’ve used hardware store “mold kits” where you tack some tape onto a surface and then send it to a service that will analyze it for you. My understanding is that these services simply look at the tape through a microscope, or apply it to a growth media that’s been prepped to “prefer” the specific types of fungus they’re looking for.
One would think there are PCR-based services that do this? That would be the gold standard for this stuff, and it could easily scale enough to become economical, but to my knowledge there are no commercial mold testers that do this.
OK, but isn’t the key take-away from the Challenger disaster all about the consequence of organizational dysfunction and fear of speaking up?
It wasn’t really a “design flaw” or “weak link” as much as it was management disregarding the warnings of engineering staff. The cold temperature limitation was known in advance by the Morton Thiokol engineers but their management refused to relay the warnings of engineering to NASA and NASA was under pressure to fly. IMHO this was a failure of multiple, mostly organizational, systems rather than “one weak link”.
Likely yes, because NASA and other agencies were able to portray the incident as an O-ring failure. It was in fact just that management was indifferent to the risk to the astronauts on board. The only individual who accurately reported on the disaster was Feynman.
The o-ring was still the weak link, a small part that decision makers assumed was insignificant whose failure caused the complete destruction of a massive system and tragic deaths. The organizational failures are just why the weak link wasn't addressed. We can say with hindsight that things should have been better communicated and the warnings should have been heeded, but the fact is they were dealing with a complex system where the risk was sufficiently non-obvious that they could disregard the warnings.

It's a vehicle to sell "access". The greed is only half of it.
The worst part is that they're selling access to foreign interests who pay them off. These people can't exactly show up with bags of gold to bribe King Sh*t Gibbon (yet), crypto is the next best thing.
It is ironic that the essay comes from UPenn in Philadelphia.
Many of you may find it shocking or unbelievable, but literacy is slipping in many parts of the US (like Philadelphia). The number of functionally illiterate people is increasing, schools are failing to educate students for a constellation of reasons.
The reality is that we instead suffer from a "tyranny" of illiteracy. I think those folks in their ivory towers, like upenn, should help to address that before starting the pearl-clutching about what has been lost because of widespread literacy.
Basically, people in Philadelphia are not allowed to write about topics that interest them, in this case literacy, oral tradition and history unless they all peraonally become elementary school teachers?
No talking about Homer or territorial expansion of 1880 for them anymore.
They mention a "quantum noise limit", that must be the ultimate precision that is physically possible, right?
What is this ultimate precision? I imagine that at some point, even the most modest relative motion at ordinary velocities would introduce measurable time dilation at fine enough clock precision.
Yes, there is a limit called "quantum projection noise" that determines how much frequency stability one can achieve with a single-atom clock [1]. With N independent atoms, this limit gets smaller by 1/sqrt(N), but with N entangled atoms one can achieve a 1/N scaling. This is the ultimate limit (Heisenberg limit).
Honestly, even TrueNAS is way more in depth than 99% of users in the wider world want. They want Dropbox at most, and very possibly they don't even want that much involvement. They want backups to just happen without having to put any thought in.
There are other motivations besides money for cranks.
In the case of Weinstein, I think his motivation has been getting attention and grievances he has with other people and institutions. I think it's OK to recognize grifting for attention as grifting. Having been a longtime employee of Peter Theil in some finance job, I expect he has f-u money by now and can thus attempt whatever he desires.
I don't know what the end-game is, but on the Decoding the Guru's podcast, the thinking has been that he is keen to be appointed to some important government role. That would be, of course, ridiculous for such an obscurantist to get an important public job, but that's ENTIRELY possible with this administration and the support of Theil.
The motivation of getting attention about the problems he believes exists in institutions (eg lack of heterodox thinking) doesn't seem like a grift to me (how broad does that definition get to be before it's just "they're doing stuff I don't like"). It seems more like he wants heterodox thinking to be able to flourish within the academics and is fighting for that, nothing grift-y about that.
> obscurantist
Nothing he says sounds obscure or hard to decipher in my reading, I never get the people who make this critique (other than try harder to decipher it, he's just using a lot of extra words/high vocabulary to be very clear about what he's saying in a compact way in order to not be misinterpreted).
>Nothing he says sounds obscure or hard to decipher in my reading
Have you listened to the Piers Morgan interview with Weinstein and Sean Carroll? In it, Weinstein appears to be using as many obscure terms as possible, in an attempt to appear clever.
I have, and that's definitely not my impression. Again to my ears that's just his natural way of expressing himself in a way that tries to express detailed ideas in a compact way. Nothing he says I find that difficult to understand with some effort (other than the hard physics). Personally I don't believe at all he's purposefully obfuscating what he's saying.
> Nothing he says sounds obscure or hard to decipher in my reading,
My dude, the guy shows up on Joe Rogan and Lex (multiple times) and talks a fire-hose of jargon to a general public audience. Indecipherable even to physicists. And what do you mean "compact"? The Rogan/Lex interviews are like 2-3 hours in length.
THAT ALONE is a clear signal he is some kind of fraud.
Capable scientists who insert themselves into public discourse are able to discuss their work at any level of detail, without jargon, and actually explain what they getting at. EW uses "Gish Gallop" tactics, I guess, to make himself seem smart. Aside from that he goes on bizarre detours where he mixes in his "geometric unity" theory with grievances about higher-ed, side-bars about Jeffery Epstein, his insane brother, and "DISC" (an acronym he coined and uses like it's now common knowledge).
Again I disagree. I've listened to many many of his interviews and it never comes across as indecipherable. If one person can understand it with some effort but some people find him hard to follow perhaps it's not that he's purposefully being hard to understand but that the audience not following isn't putting in enough effort or just giving up and calling him 'jargon filled' when there's actually a real clear understanding to be had behind what he's saying, to put it bluntly and at a risk of an angry response.
... and in the cases where one does manage to put in the effort to understand what EW is actually saying, the ROI has been trite and uninteresting and could have been said with simpler words and gotten to the point in far fewer words.
Example: See the conclusion of Nguyen's teardown response paper to "Economics as Gauge Theory": https://arxiv.org/abs/2112.03460
Basically... 1) Tautology, 2) Inconclusive, 3) Not usable
Yeah, that would be nice, but it is SO RARE, I've not even heard of that being possible, let alone how to get at the metadata with godforsaken readers like Acrobat. I mean, I've used pdf's since literally the beginning. Never knew that was a feature.
I think this is all the consequence of the failure of XML and it's promise of its related formatting and transformation tooling. The 90's vision was beautiful: semantic documents with separate presentation and transformation tools/languages, all machine readable, versioned, importable, extensible. But no. Here we are in the year 2025. And what do we got? pdf, html, markdown, json, yaml, and csv.
There are solid reasons why XML failed, but the reasons were human and organizational, and NOT because of the well-thought-out tech.
That said, if you don’t like it, disregard it. No one is forcing you. I think it has too much emphasis on protein but that’s just me.
