SpaceX is what it is because the vision is much less tyranny of the masses, and much more damn the torpedoes no one can stop me.

Apple did not need to be controlled by a majority shareholder in order to follow an ambitious, cohesive vision.

I've been trying to square the physics and my experience.

Pedal B flat is the fundamental, low B flat is the 2x, F 3x, mid B flat the 4x, D the 5X, high F is 6X, G half sharp is 7X and high B flat is 8X.

I've always been amused at how many sources state the "tube with one end open" model, derive the "odd harmonics only" behavior from the model, and then never engage with the observable behavior of the instrument or reconcile it with the model.

I did find this when trying to understand that disparity, but I don't know enough to confirm/refute/amend the explanation:

I took that to mean ≈ "Amount of training data isn't the big factor dwarfing all else." Depends who "we" refers to, I guess. Back when LLM-generated code was new, I definitely saw predictions that LLMs would struggle with niche or rarely used languages. These days, consensus among colleagues within earshot is that LLMs handle Rust much better than Python or C++ (corpus size and AutoCodeBench scores notwithstanding).

And yet a lot of speakers still seem to need that self-evidently true statement pointed out to them. Tautological advice isn't necessarily bad or useless, especially for beginners.

Ever try or even see a "Leet-Code" style question that stated the problem without providing example results?

This style of question asks the examinee to devise a procedure for producing those results, not to come up with the individual results themselves. If a student is given a bunch of systems of linear equations to solve, an answer key isn't especially useful since checking a candidate solution is pretty straightforward.

We could be extremely, reductively classical about it and say that all of Nerdle's answers point to the same place (⊤, since any answer equivalent to ⊥ is disallowed by the rules), but the real answer is that Nerdle—like Wordle—is simply about finding the right piece of syntax, not finding the right semantics.

Python's OOP is awkward with object.f() meaning something different from f(object), when really they ought to mean the same thing.

Why should they? Coming from other OO languages, I would expect `object.f()` to involve a vtable lookup, or something similar that effectively has `object` carrying around its own particular implementation of `f` (which might have been closed over some hidden internal state as well), and I'd expect `f(object)` to not do anything of the sort.

In Pandas, you sometimes have a function with the same name as a method, which behave subtly different from each other.

This sounds more like a poorly designed library than any language-level awkwardness.

Figure 2 shows plots of overnight and intraday returns for twenty-one major stock market indices around the world. Turn the page and compare Figure 1 with Figure 2. See if you can tell a difference.

These images... do not render well on my machine, to put it lightly. So they look remarkably similar to me. Perhaps the author could spell out what this difference is? There is eventually mention of "striking similarity in the overnight and in- traday return patterns in the indices around the globe," but I don't think I'm ready to conclude that strong correlation of phenomena across markets in a global economy must be caused by a collection of manipulators acting on all of those markets.

I'm curious to see what others have to say, since I lack the hardware and background to properly read this document.

The issue is about which edges are in the same plane as which other edges. If this is a polyhedron, AD and BE must be coplanar, and BE and CF must be coplanar. Extending the edges into lines, they don't form a 3-way intersection. G gets projected to the same screen point as some point on line AD, but the only way G can be on line AD is if AD and FC are coplanar. If all three of AD, BE, and FC are coplanar, the entire figure is a flat pentagon (and DE, BE, and FE are not edges).

If G isn't on line AD, then BE and CF can't be a side of the same truncated pyramid.

A quick internet search turned up plenty of speculative results positing that dogs tilt their heads to hear better, to listen for specific words or tones, or to see past their snouts. Sommese found one poster hypothesizing that shelter dogs do it more often because they know on some level that humans find it irresistible.

Amusing to see this play out again in the comments here

Interesting that this is pointed out, since I noticed they linked to this article, describing these sorts of jobs being a "teenage rite of passage" to be a myth.

The hyperlink's text claims it is a myth, but the linked article does not refute the idea that working this kind of job is considered by our culture to be a significant growth step for teenagers.

Catplosions (Tarn loves cats, cats reproduce, too many cats kills DF performance)

This was a particularly insidious one because the usual strategy of culling excess livestock doesn't work out when applied to dwarfs' pets (pets can't be designated for slaughter, and other means of making pets die will make their owners upset). With most animals, you can avoid the pet adoption issue by just not marking them as available for adoption, so you wouldn't have to worry about a dogsplosion, sheepsplosion, etc. Cats do not become pets through that system. Instead, a cat adopts a dwarf.

When you make a better compiler/runtime, that work on one program benefits many programs. So it is often more cost-effective to improve the compiler/runtime than to improve all the user programs. Developing higher-level languages creates a similar situation: many programmers can be more productive.

this announcement, which essentially amounts to "leading VR platform tests new way for developers to monetize applications with personalized ad service". People seem to think this is Facebook injecting ads into games all willy nilly, when in fact it's just a platform for developers to add ads to their VR apps/games.

This piece (along with others I've read) attributes the action only to Facebook and not to game developers, so readers are likely to miss that part.
