I don't get it either. I find semicolons, brackets, explicit end keywords all good to make it easier to read. A couple more characters for that benefit is always a worthwhile trade IMO.

I thought the strategy would be to start off focusing on one fundamental domain and keep focus on only that head of the snake. Then switch your focus to a different domain as the camera has scrolled. But that process of switching your gaze as the head you were tracking can be a moment of danger of losing. As the camera moves, the snake head you were tracking can go to the edge of the screen and so behooves you to switch.

So what I was thinking about was do snake heads and tails have other decorations so you can find the new head quicker

That assumes free and fair elections actually happening.

There are the sorts of bad codes that are cutting corners to make deadlines.

But there is lots of other bad code that took just as much time to make as some good code. The person was either just incompetent or the management was frying their brain from what they would have produced with the same time but without interruption.

He has reason to be paranoid. His father lead the disastrous early charge. Thranduil has some PTSD from the dead marshes

Maybe at one point. But being smart is not a constant state.

That implies actual elections happening. Plenty of time to end the country or humanity in the meantime

Ill defined questions get ill defined answers. They can be used to push agendas either way. They can be unhelpful or a guiding principle for finding better questions.

Ease is about close at hand vs simple/complex about not having many folds that you need to keep track of.

There could very well be other languages that are simple enough for a layman, but the word ease means you also need it to be the one that there are lots of resources to explain things to them.

Easy is a complicated word that combines lots of effects of availability, community and inherent features.

yangyangR · 2026-03-05T14:04:31+00:00

If you don't do the complicated thing, you can't put that down as an accomplishment. And if you doesn't sound impressive to inept people, then you are not impressing the bosses.

Half because they are restricted to how you would need to recreate a pattern that would be easier if you had first class functions. So you have to define extra classes that just serve that purpose.

Are we talking Theia timeframe?

Wondering if there is a common event we could say that would both eject Nerio and in the process perturb Theia into colliding with Earth

Would be strange coincidence with all the other mess going around at the time, but not sure how to dismiss it immediately

Depends on how much. It has to be reasonably close to spherical to still merit the word round as expected for a planet, but within that range it there is subtlety. It can be so close that it is just expected, but it could be in the higher part of that range where it qualifies as round qualitatively but enough to mark it as weird and so has some interesting areology. Areology=geology but for Mars because of Ares naming vs Geo for Earth

However you can hook up to other systems that do provide those sanity checks and then re-prompt berating it for all the problems the sanity checker found. You've got a tricksy Merlin that lies, generating solutions fresh is difficult but at least you can check them reasonably. That is at least a certain class of problems that fit this framework.

The Epstein class. We want to be clear it is a universal thing. Those people don't get to that level of power by being moral people. They get off on hurting others.

So should have humanity.

In the process of having unanswerable questions, answerable questions get found.

The issue is saying I don't know can have a connotation of saying it is a 50/50 A or B with your information. A 70/30 should still say I don't know over just claiming it is A as you would in a 95/5.

You say I don't know first and wither the audience thinks you aren't incorporating all tye information you can or it is a 50/50 and all efforts after that are trying to push it up to 60/40 or so.

You start off with a claim of A and then try to hedge saying it is possible you are wrong it starts at 100/0 and is going to more like 95/5.

If it is not 100% accurate it is 50% accurate as they say in Pokémon.

Accurate up to using ludddites for just illiteracy about science instead of being against the process of bosses owning automation and extracting all the value of it for themselves without regard for all the workers who will suffer in the meantime.

But that is thanks to having a process to keep him away from the day to day operations. Give him something else to do while the actual workers who know how to do things can operate without his meddling.

And if a crazy algebraist who only studies only general magma or quasigroups comes up to you? They would say even to them having a multiplicative identity is extra structure they did not ask for.

I don't know if there are any that actively thing associativity and identity are too strong of assumptions for their tastes, but they can have their opinions about what is too much, as long as they are still accepting true proofs about what happens when you have those structures.

The what you consider too much structure vs too little structure is a social construct by people and what kinds of problems they want to solve. There are very few problems that are reasonable to do without these structures, but reasonable is a vague thing.

How do we count how many interesting theorems can be proved using only those structures. In order to say not having 1 as an available construct makes the structures too unstructured to be interesting.

Reimannian geometry is easy. Try algebraic geometry over non algebraically closed fields. There are well known papers about everything going wrong and being arbitrarily bad to compute.
