This is what the DOGE guys don’t understand: even if it seems you can easily replace something, you will find out that the devil is in the detail.

Never ask ol' Chesterfield about his fence.

Ahem, "blow some my way"! For fence-related matters Chesterton is the person to ask.

My friend is a doctor. Her profession uses sections of the NIH and CDC websites on a daily basis. They are the references for drug interactions with medical conditions. These sections are just gone . Trump’s “cost saving” measures are already actively harming medical treatment in the USA.

I'm sure the NIH isn't the only entity with access to pharmacology information...

Can we please not DOGEify every comment thread? I know that it's on a lot of minds all the time, but we have a whole spot on the front page effectively reserved for DOGE 24/7, and I'd like to see literally anything else in the other 29 slots.

I agree its quite annoying. But it only comes up because of the massive change it will cause across the whole country and it's important to remain prepared for implications.

I attended a woo-woo university course, where the instructor invited a interpretative dancer to give a lesson. The dancer bright out some paper, pencils, and almonds, and had everyone spend half an hour silently writing about their single almond. As it turns out, it's easier than it sounds; time passed quick and I (and most others) never felt bored. There's always more room for observation and analysis. It struck me…

I think there is a fine balance to this. I agree that going through life by experiencing as much as possible is futile. But on the other hand, spending all your time in thought is also problematic since your ideas never clash with reality.

E.g. see the "Open Door Policy" from Hamming's research talk: https://gwern.net/doc/science/1986-hamming#open-door-policy

People disagree with my opinion, therefore it's circular? Interesting logic.

Did you read the remainder of the comment? It seems pretty clear to me at least why it would lead to circular arguments.

At this point, I've presented a handful of fairly straightforward hypotheses about cause and effect. They could be wrong, but it's on you to show that they're actually self-referential. There is no amount or kind of other people's opinions that will make them so.

A large percentage of HN's population doesn't live in the US, and many of those of us who do have other ways of keeping track of what's going on. Threads about DOGE on HN are not useful, they're almost always just flame wars. Those who feel enlightened by them can join the daily thread that inevitably pops up and leave the rest of us to talk about other things.

The universe seems to have a fractal structure. At every scale we can look there is a huge amount of detail.

One thing I find interesting is the apparent "End of Greatness". It seems like the fractal nature of reality has both an upper and lower bound? > The End of Greatness is an observational scale discovered at roughly 100 Mpc (roughly 300 million light-years) where the lumpiness seen in the large-scale structure of the universe is homogenized and isotropized in accordance with the cosmological principle. At this scale,…

Possible, but since that scale is so far outside of human experience it is possible there is detail there that we are unable to perceive using our most modern techniques.

why is our perception and the way it works different from the universe? with enough agency, and ignoring everything else in the world you realize that your perception is all there is, that you can ever be sure of. There is no universe, there is no quantum physics. Those are just models, your perception models them.

Surely, keeping a 1:1 match between our perception of the universe and the universe itself is a kind of order that would be constantly under threat by the inexorable move towards increasing entropy. The lack of match either now or in the future is what you would expect. Chaos is the expect state, order is the exception. Hence you should not expect for that match to exist by default

I read recently an article on HN that basically entropy (and hence increase thereof) is just a statistical model of uncertainty of the things we don't know. As soon as our understanding (of e.g. positions and velocity of individual molecules) increases, that what we call entropy, decreases. At least my understanding.

There's the reasonable amount of oversimplification necessary to just get through life, then there's actively trying to oversimplify because it makes life "easier". I judge people very harshly based on whether they accept reality as complex or rail against it. I am not proud that I do it, but it seems like it has value. I feel like strong yearnings for simplicity (and willingness to ignore messy reality) correlates w…

Reading Ian McGilchrist’s “Master and his Emissary” has been incredibly eye opening on this theme. Oversimplification and getting upset with the world when it doesn’t fit your model of it is definitely a poor character trait —- which is nevertheless unfortunately trained and rewarded in our schools and much of our professional work. The world is what it is and there are some helpful abstractions for navigating it, bu…

Indeed, often when we humans are upset about something, we later understand things better. Then comes that aha moment in which we see we were jumping to conclusions.
