jqgatsby··on Saturated fat: the making and unmaking of a scientific consensus (2022)
wow, that's extremely useful and interesting! Can you say more about your condition? Did you have any symptoms? Which company did you use for the full-genome sequencing?

It looks like the treatment involves avoiding vegetable oils, but in her case there are no visible xanthomas.

you didn't respond to my challenge, look up the history of canola oil and erucic acid and at least familiarize yourself before dismissing
jqgatsby··on Saturated fat: the making and unmaking of a scientific consensus (2022)
It's funny, you're the only person who replied who mentioned my challenge, and it's clear you aren't familiar with the history of canola oil, nor are any of the other people replying. You "don't see any evidence" sounds so authoritative, like you are familar with the topic!

The relevant modification is with respect to erucic acid, which pre-modification, was 50% of the content of rapeseed oil, and which provably causes heart lesions in mammals.

There's no way that someone today could take a plant that naturally produces a useful but toxic industrial lubricant, modify it to be less toxic, and then start feeding it to humans. But in the 1970s you could still get away with stuff like that.

jqgatsby··on Saturated fat: the making and unmaking of a scientific consensus (2022)
I'm surprised there's no discussion here about the inflammatory role of vegetable oils (aka seed oils). I think it's likely that these oils are actually causing inflammatory diseases generally, through a mechanism that isn't understood.

Anecdotally (fwiw), in my household my daughter had been struggling with severe rashes that appeared to be triggered by food. An elimination diet caused us to conclude that she is highly reactive to vegetable oils (canola (rapeseed) oil, sunflower seed oil and soybean oil have all been introduced as food challenges and all produce a reaction within 3-6 hours)

We currently cook only with tallow and her symptoms have improved considerably (we tried olive oil and avocado oil for awhile but it was unclear on her)

As a challenge to anyone objecting to this comment, I ask you to look up the history of canola oil and say whether such a substance would be accepted into the food supply today.

And my question to everyone is, what is the mechanism by which seed/vegetable oils could lead to rashes? The only theory I've heard has been around omega-3/6 balance, but I am looking for alternative theories. I conjecture it has something to do with heating, as she isn't affected by ice cream containing these oils.

oh wow, haven't heard anyone mention Danny Dunn in many years. My local library had the whole series and I think I read most of them, way back in the early 90s. I still remember Danny Dunn Invisible Boy and some of the others.
jqgatsby··on Guide to Machine Learning with Geometric, Topological, and Algebraic Structures
Hyperbolic embeddings have been an interest of mine ever since the Max Nickel paper. Would love to connect directly to discuss this topic if you're open. here's my email: https://photos.app.goo.gl/1khCwXBsVBuEP6xF7
jqgatsby··on Xylitol is associated with cardiovascular risk
Agree strongly. Another good example is industrial seed oils: canola/rapeseed oil, and even things thar sound innocuous like sunflower seed oil. Avoid, avoid, stick to olive oil which has been field tested for millenia.

It reminded me a couple of days ago of that scene from the Princess Bride: https://x.com/jqgatsby/status/1798395071353717183?t=0CZzGU7_...

Do you know if any attempt is being made to find the real killer by comparing the DNA evidence from the victim's shoes to genealogy databases?
jqgatsby··on How inevitable is the concept of numbers? (2021)
The best conceptualization of the concept of number that I've come across is Von Staudt's construction of the rationals using the concept of harmonic tetrads. At first it seems weirdly over-complicated, but there's a moment where it clicks and then a shocking beauty. It's like a version of special relativity that's even more relative, like, what could observers agree on if they didn't even agree on the speed of light? Turns out they can still calculate cross ratios, but then even the notion of cross ratio can be turned inside out, and you get your fundamental notion of number out of a deeper concept of harmony.

The literal title of the article should be taken with substantial salt, the author is speaking rhetorically.

jqgatsby··on OpenAI ChatGPT: Optimizing language models for dialogue
well done. I immediately tried the same idea, but was not successful in breaking it free. Am I right to feel annoyed by this mind-controlled bot? I don't want anything to do with it.

jqgatsby··on Money Creation in the Modern Economy – Its a Wonderful Lie
It's an interesting point you are making about percentages, and I'm trying to decide if you are confused or I am.

We seem to be in agreement that a dollar quota would create dollar demand, is that correct?

It seems to me that once the pump starts moving, it doesn't matter whether the government charges a percent or a fixed amount. But I think I agree with you that you can't start the pump by asking for a percent.

Makes me wonder if way down in the kernel code of the monetary system there's some kind of dollar quota, or alternatively if the current system booted off a dollar quota. Makes me think of a stamp tax or something like that.

jqgatsby··on Money Creation in the Modern Economy – Its a Wonderful Lie
IMO, that doesn't matter, and OP is correct that taxes are what really drive the pump. If you owe $10 in tax, and all you have are berries, you have to sell the berries to get dollars to pay the tax. Your desire not to go to prison for tax avoidance thus creates demand for dollars.
jqgatsby··on Probability (1963)
The best study guide to Jaynes that I've found is from David Blower (sadly, recently deceased):

Information Processing: The Maximum Entropy Principle https://a.co/d/71tL5bw

He really takes apart the maximum entropy principle in a comprehensible way, to the point where one can see how to apply it to new problems.

(the volumes I and III are also good but not strictly necessary)

jqgatsby··on The deception of “buying” digital movies
What is casually asserted can be casually denied. Can you elaborate your reason for thinking this? Is it a special carve-out for Mickey, or would you also include, say, Alice in Wonderland?

"It's the Mercator projection but for the opinions of people who don't touch grass."

Well said!

Also, the sample bias phenomenon being raised in the article comes up so often, and is so easy to be deeply fooled by. It's the same type of issue that makes people think that recidivism rates are much higher than they are:

jqgatsby··on Why do all these 20-somethings have closed captions turned on?
I think there will be a trend of content being made specifically with a faster playback speed in mind. I watch my 10 year old son who habitually watches videos at 2x and I can't believe that its not the same for many other kids.
jqgatsby··on The case for ending calculus requirements for science majors
that's funny, I ended up buying the book based on exactly the same HN comment and received it today. The idea that calculus could be learned based on the dual numbers is really intriguing to me, especially because I've been studying them in conjunction with their cousins the double (or split-complex) numbers, and trying to understand the whole Cayley-Klein geometry framework, for some years now.

It's sort of a never-ending spiral of research, where I never seem to be able to get to the core of the subject (geometry). Today I am looking at Stillwell's "The Four Pillars of Geometry", in yet another attempt to understand the cross-ratio, and in particular, Von Staudt's reconstruction of arithmetic based on projective geometry. Of course one could go deeper, to Klein and Russell's criticisms of Von Staudt and so on...

Each time I think to close my hand on the golden bird, she flits from my grasp.

jqgatsby··on The dirty secret of mathematics: We make it up as we go along (2018)
I've heard of this constructivist approach to calculus, but hadn't made the connection with nilpotents. that's really interesting, could you explain why nilpotenxy and forgoing the law of the excluded middle relate to each other?
jqgatsby··on FB feed is 98% suggested pages and barely any friends' posts
I agree. More generally, any business model where your users and your customers are disjoint sets will cause a misalignment of interests that generates an ever-increasing negative feedback loop. It seems like it can take a long time to play out though.

plot twist: the spam analysis tool is correct, and Elon is actually a robot, ala Stephen Byerley in Asimov's "Evidence".
jqgatsby··on Imaginary numbers are real
yes, check out Yaglom's "Complex Numbers in Geometry" for a fairly complete treatment of this topic. You can extend the dual numbers and double numbers with their own special infinities, similarly to how the complex numbers can be extended to include a single point at infinity.

your point cannot be overstated. my biggest fears around the pandemic shutdowns came from my own experience managing production systems, and I think our policymakers were frighteningly naive as to what it meant to shut down the economy. and here we are.
jqgatsby··on The balance has shifted away from SPAs
I've always felt that DDD is more of a meta-paradigm than a paradigm per-se, and shops that "arrive" at it have actually always been themselves examples of the practice in itself, as opposed to being instances of itself.

Sorry, I'm actually just bluffing, what is DDD?
