generalenvelope commented on The death of partying in the USA   derekthompson.org/p/the-d... · Posted by u/tysone
generalenvelope · 2 months ago
It feels ridiculous not to mention car dependence and the things that enabled it: restrictive zoning, parking minimums, the car lobby.

In the last 50 years, the US has bulldozed dense, mixed used housing that enabled community and tight knit neighborhoods. More economically/socially viable housing (read: an apartment on top of a business) has literally been banned in much of the US. Ensuring that there's a large plot of asphalt to house personal vehicles that are ever increasing in size is baked into zoning laws (though some cities have finally banned parking minimums). Suburbia sprawls, literally requiring most of the country to own a car.

I would love to see some data on this, but my intuition is that everyone is physically farther away as a result, which weakens their general connection and likelihood to party together, and makes it harder for them to get to/from a party in the first place.

There's other feasible side effects too like less savings due to the cost of owning a car (I've seen estimates of the US average exceeding $10k/yr), or expensive housing exacerbated by all of the above - less space for housing due to roads/parking (and the cost rising as a direct result of a developer needing to include parking), and rising taxes to finance more and more infrastructure: suburban sprawl means more roads, pipes, electrical lines, while contributing significantly less economic value (Strong Towns has done some great graphics on how much dense urban areas subsidize their sprawling single family home filled counterparts).

Curious why you chose C++? Were there aspects of other languages/ecosystems like Rust that were lacking? Would choosing Rust be advantageous for blockchains that natively support it (like Solana)?

To be clear: I don't mean to imply you should have done it any other way. I'm interested mainly in gaps in existing ecosystems and whether popular suggestions to "deprecate C++ for memory safe languages" (like one made by Azure CTO years ago) are realistic.

Like most people I want to live a long time. But more than life span I am interested in health span. I want to feel good and be autonomous as long as possible. Fitness, especially good muscle mass, is an important part of that.

I haven't seen anybody mention NvChad, which is a popular pre-configured neovim setup with lots of documentation (and a community of support). You're still free to customize, but it saves a TON of time in terms of getting to the foundational editor features.

https://github.com/NvChad/NvChad

The author mentions switching from editor to terminal often - NvChad has built in terminal integration so you can toggle floating/vertical/horizontal terminals (whose contents persist when closed) with a simple keybind.

This year I got pretty consistent at strength training twice a week, a lot of times I'm dead and tired but I make sure I get to the gym and at least get one set of my workout done to (a) keep the routine going and (b) not be as sore the next time. I only train my whole body once a week, but I'm happy for now with that since I just don't have the stamina to push more without neglecting my life and hating the workout sessions.

For next year, I want to start taking actual meditation courses and build a regular habit to meditate before going to bed. On top of that, I want to also relax and unwind after work without being on my computer, phone, or the TV (it's ok to pick those things up later, but I just want to rest first without screens)

Highly recommend Barbell Medicine if you're interested in evidence based strength training info. The best workout routine is one that you enjoy and adhere to. Progressive overload (which is NOT just adding weight) is important for progression too. But you probably don't need to go "as hard" as you think - somewhere between 2 and 5 repetitions from failure (RPE 5-8) is fine assuming you're in it for general fitness/health (but even if you aren't).

I have just used it yesterday to better understand a math problem and found that the edit-compile-run cycle of rust with this framework was prohibitively long.

I only had a single file calling into this lib - maybe I could have improved on it with splitting the project up to some modules? Could anyone comment on their experience? Because usually I have found rust compile times okay, but this really made it hard to iterate.

What linker are you using? I've gotten really significant speedup over the default linker by using lld or mold.

Who's Alan Flanagan and why should I listen to his opinion on Huberman?

From what I can tell, Huberman is a neuroscience Ph.D. whereas Flanagan is one in nutritional science is that right? If so, by credentials alone, Huberman seems like a better reference in matters of the nervous system.

Note that I have no horse in this race, I'm really just curious!

Alan has an MSc and PhD in nutrition and runs Alinea nutrition.

I can't speak on Huberman's assessment of research in the neuroscience space, where he has expertise. Alan has done some breakdowns of Huberman's broad claims related to nutrition, and how they're generally hyperbolic and lacking sufficient evidence (ie they're not based on studies that show outcomes in actual humans in a controlled fashion). The folks at Barbell Medicine have spoken to some of his generic health/fitness claims as well, to similar effect.

I think Huberman uses his platform and title to paint overly broad strokes about all kinds of things outside of his expertise. Some of this could be attributed to a platform like twitter that prioritizes small amounts of text, but overall I think it's disingenuous especially as someone claiming to be an expert. I think if he were more interested in helping people he would focus less on money/fame/views and take a more nuanced approach, instead of (mis)leading people to change based on extremely limited evidence. The problem is he wouldn't be able to churn out so much content if he did so.

I have no reason to doubt any of his academic qualifications. But I have a lot of appreciation for the breadth and depth of knowledge required to speak confidently about the latest evidence in a field. This becomes a problem when the field is outside of one's expertise. Alan goes into this in detail on his instagram post.

I realize the post is based on something Huberman said within his expertise. But I think the context is important to understand, as it makes me wary of listening to him in general.

If Huberman mentioned it in a podcast, it must be true and groundbreaking way to hack your brain to a better life!

I can't wait to stare at this thing !!!!

generalenvelope · 2 years ago
Huberman's pretty good at taking research he doesn't have the expertise to assess out of context and turning it into some protocol that everyone needs to do.

The vast majority of things he talks about, if beneficial at all, are at the margins and people stand to gain far more from doing things like exercising and eating vegetables more.

Edit: Alan Flanagan has spoken on the Huberman paradox in detail: - https://www.instagram.com/p/CkLPU7BMiIN/ - https://www.youtube.com/shorts/Bgc3uGu0uoI

Benjamin Bickman - Why we get sick.

A life changer. Makes a compelling case that insulin resistance is at the root of many illnesses. Clarified my nagging questions about added sugar vs sugar in fruits (both are bad) and gave me a simple way to make food choices. Convinced me to finally go LCHF (Low Carb High Fat) or Keto.

I don't mean to rain on your parade - but the reason I've heard of this book is red pen reviews: https://www.redpenreviews.org/reviews/why-we-get-sick/ Which didn't give it a particularly favorable review in terms of scientific accuracy
