Git VS PineappleCAS

Boy, I can't find this either (but also, the kernel mailing list is _really_ difficult to search). I really remember Linus saying something like "it's not a real SCM, but maybe someone could build one on top of it someday" or something like that, but I cannot figure out how to find that.

You _can_ see, though, that in his first README, he refers to what he's building as not a "real SCM":

Here is the direct link, as HN somehow removes the query string: https://github.com/git/git/commits?author=peff&since=2023-10...

I understand all that.

I'm saying, if you write a survey and one of the possible answers is "diff", but you don't clearly define what you mean by "diff", then don't be surprised if respondents use any reasonable definition that makes sense to them. Ask an ambiguous question, get a mishmash of answers.

The thing that Git uses for packfiles is called a "delta" by Git, but it's also reasonable to call it a "diff". After all, Git's delta algorithm is "greatly inspired by parts of LibXDiff from Davide Libenzi"[1]. Not LibXDelta but LibXDiff.

Yes, how Git stores blobs (using deltas) is orthogonal to how Git uses blobs. But while that orthogonality is useful for reasoning about Git, it's not wrong to think of a commit as the totality of what Git does, including that optimization. (Some people, when learning Git, stumble over the way it's described as storing full copies, think it's wasteful. For them to wrap their heads around Git, they have to understand that the optimization exists. Which makes sense because Git probably wouldn't be practical if it lacked that optimization.)

The reason I'm bringing all this up is, if you're trying to explain Git, which is what the original article is about, then it's very important to keep in mind that someone who is learning Git needs to know what you mean when you say "diff". Most people who already know Git would tend to gravitate toward the definition of "diff" that you're assuming (the thing that Git computes on the fly and never stores), but people who already know Git aren't the target audience when you're teaching Git.

Didn't Git have a new default merge strategy, `ort` https://github.com/git/git/blob/master/Documentation/RelNote... ?

Yes, but you are referring to standalone scripts, not functions defined within a Bash script.

Compare for example the following helper code used for git command completion inside Bash and inside PowerShell.

You can use the Pineapple cas. Just note that it is still highly recommended that you learn to do derivatives on your own.

Unfortunately, this would require a CAS, which none of the 84 series has. You can use PineappleCAS to do it, though.

CASymba (still active, features and bugfixes being added), PineappleCAS (not maintained anymore)

I was wondering what programs I could use during the Calculus BC Test and if there were any programs that are prohibited. Specifically, I wanted to know if this was allowed or any other programs similar to this - PineappleCAS

https://github.com/nathanfarlow/PineappleCAS There is PineappleCAS for the Plus CE

CASymba (repo/doc ; download) is a new CE CAS engine alternative (or complement) to the well-known PineappleCAS, and it offers other various features

I mean, you could just do it by hand? for zeros of x = 1, 3, 5, the polynomial is just (x-1)(x-3)(x-5). If you need it graphed, then that can be used directly. If you want the equation, then you'd want to look for a CAS that could do the expansion for you. Perhaps PineappleCAS? (Disclaimer: I haven't used PineappleCAS, so no clue how it is)

Unfortunately, the TI-84 Series does not have a CAS (Computer Algebra System), which is what is needed to simplify radicals. You can download PineappleCAS by Nathan Farlow to add one, but be careful. Using it on a standardized test counts as cheating.
