Nitpick: Indicate it can. Not that it will.

The point is that the equations don't tell you what would happen. Both options would be valid according to the equations. This is completely contrary to our intuition about Newtonian mechanics. The question "given this situation,

Nothing. The Newton equations predict that, given the Norton potential, there are two possible trajectories that solve them. The next state is not uniquely determined by the prior state, so asking what makes the ball roll shows that you don

Do you understand the difference between Norton's dome and other domes with balls at rest on the top? The very point of non-determinism is that the next state doesn't follow uniquely from the current state, causality is broken. Th

Seriously, you don't seem to know much about things you speak confidently about. Norton's dome is a surprising mathematical situation in very conventional classical mechanics. It doesn't matter what else Norton has done, this

What is "magical wand" here? This is simply Newton's equation and a specific dome shape. Trivially no perfect bodies can be built experimentally, and it's specific properties are not robust to perturbation, but there is

Pontus gave a good explanation of the physics. Mathematically the statement is simply that there are different trajectories with the same initial conditions that solve the same differential equation. This is easy to calculate and has nothin

Yes, the second case is a bug in the interface. For the first case you have it the wrong way around. My generic code would work on things that are not numbers but I prevent you from calling it because I didn't anticipate that there wou
279.
by Certhas 2y ago
Yes, but generic code complicates the picture. The things I saw were like: The documentation says you need a number but actually all you need is for the + operator to be defined. So if your interface only accepts numbers it is unnecessarily
280.
by Certhas 2y ago
But if the info is info the user of your code needs in order to interface correctly, the point that you can't document everything is moot. You already have to document this in the documentation anyways.

It's also not truthful because many of the Rust maintainers are long time C contributors. Marcan also linked to this resignation of a Rust Maintainer: https://lore.kernel.org/lkml/20240828211117.9422-1-wedsonaf@...

If you buy the "git is just a tree of commits and pointers" mental model it's absolutely not a surprising side effect but would be the logical thing to expect. I moved a pointer to a commit around, why would that change where
288.
by Certhas 2y ago
To me that looks like git is leaking implementation details left and right. So much for "a branch is simply a pointer to a commit"...
289.
by Certhas 2y ago
The real "internal model" of git contains much more data/moving parts. There isn't one tree of commits, there are typically at least two: local and remote Branches are not just pointers to commits, but also possibly rela

As someone noted in the thread on OpenAI restructuring: Maybe these messages are not meant to convince outsiders but to reassure insiders/true believers. It provides them with a ready made narrative to counter the cognitive dissonance.

Honestly though: Why? Large chunks of the most important servo work is in Firefox now. Nobody else maintains even one web engine. What is the importance for the open web of Moz developing two?

With all due respect, it does not look like you have looked at any of this earnestly. First of all, the results are not marginally significant. In every variant of the analysis, the results are significant at the p < 0.001 level. This is

I used to do that in Python with the numba jit. Write Python code that generates a Python code that then gets compiled. It's a fragile horrible mess, and the need to do this was a major reason for me to switch away from Python. It&#x27

We now live in a 1.5 degree warmer world. We can empirically study how much that level of warming is costing us already. It turns out that the measurable effects of warming on GDP absolutely dwarf the costs of mitigation. Ignoring climate c

And the reason to dismiss c) and d) is so that the difference between the delimiters is the length. That's not exactly profound either. If the word for word same argument was made by an anonymous blogger no one would even consider citi

Argument by authority. To me 1 based indexing is natural if you stop pretending that arrays are pointers + index arithmetics. Especially with slicing syntax. It's one of the things that irked me when switching to Julia from Python but

I agree that the change isn't of comparable magnitude. But JJ changes the user facing conceptual structure of version control. It unifies working directory, stash, index and commit, and replaces them with a single thing. And it shows t

I feel like one of the reasons I see the problems with git more than many commenters on here is precisely because I often teach beginners who do not have a CS background.
