So…if we had already been using a base-12 counting system when metric came along, we would have the best of both worlds.

Without necessarily endorsing the article's ideas....I took this to be like the diamond-inheritance problem. If service A feeds both B and C, and they both feed service D, then D can receive an incoherent view of what A did, because no

OOPs = "object-oriented programming", BUT it's a more restrained and thoughtful complaint than just "objects suck" or "inheritance sucks". He cabins it pretty clearly at 11:00 minutes in: "compile-t

I've seen a db mock work when 1) there was a small subteam in charge of the OR-mapping, schema structure, and included a DBA; and 2) also a design policy from the architect that all objects had to come out of factories. Under those sp

I like this - nice playing around. We usually think of this kind of tree as having directed edges from parent to child, e.g. from set to element. In your graphs, you're erasing the direction of the edges, which uncovers a neat little

They are different: in the U.S. that's why "freedom of the press" is also written down in the First Amendment, and historically, that's exactly how the U.S. courts have interpreted the phrase "freedom of the press&

Alice is taking a small unfair advantage of every member of the community at once. A community and its practices is a form of commons shared by the members, so it's vulnerable to the tragedy of the commons. If one member acts in a wa

> I'm not sure "it can be generalized to an undecidable problem" really explains why it's hard.... Hah! I agree with this. :)

In fact, according to the Esolang Wiki [ https://esolangs.org/wiki/List_of_ideas#Mathematics ] , Gregory Chaitin apparently has built a Diophantine equation whose parameters encode an entire Lisp interpreter.

Yeah, this is a little bit subtle. Please ignore the lack of rigor below, but this is my understanding: They aren't looking at a particular polynomial like 4x + 3y = 2. That has a solution x=2, y=-2, but they don't really care

Not OP but for me, it’s that public answers here are available to all of us. That’s great!

I read this as basically arguing that our filters throw up too many false negatives, like Kariko, in a high-risk/high-reward environment. It’s saying the cost of false negatives is way higher than the system realizes, and that’s becau

Thanks, I appreciate that! For you personally, are you thinking more code-focused, what-can-I-do-with-this, or more theory, what-is-a-qubit/quantum-gate kind of stuff?

Trying to explain is dodgy - it never works for jokes, either. But I think they represent a bundle of interesting contrasts that hits a sweet spot for a lot of us. Most people have made a Mobius strip out of ephemeral paper and thrown it

You may be thinking of Polya's result, which lets the walker go anywhere on the grid, so there are more possible states than Poincaré allows. For a discrete system, Poincaré assumes (roughly) that the space of possibilities is finite.
