The Anticlimax of Internet Searching
Tuesday, July 15th, 2003It is so frustrating when you are searching for an answer to a question and all you find are pedantic comments and clarifications about the question, with no one bothering to give you a freakin’ answer. Here is a perfect example of this ridiculous tendency:
> I would like to know if there is a general solution for any two
> quadratic
> equations of the form shown, solving for x and y which satisfy both:
> A(0)x^2 + B(0)xy + C(0)y^2 + D(0)x + E(0)y + F(0) = 0
> A(1)x^2 + B(1)xy + C(1)y^2 + D(1)x + E(1)y + F(1) = 0Except for degenerate cases, the solution will involve solving a
fourth-degree equation in x or y (the resultant of these two polynomials
with respect to one of the variables). Geometrically, two conics
can intersect in four points.
The reason I am looking for this solution is that will allow me to intersect quadratic bezier curves (the basis for all my 2D shape drawing), allowing for sophisticated boolean operations.
I already KNOW that the answer will involve a fourth degree equation. I just want to know what it is! This guy’s response is useless and simply wastes my time as I search for an actual answer [this post is from a newsgroup a year ago]. There are too many dickheads in the world who will reply to such a question without actually answering it. When someone asks on a public forum: "How do you achieve X?" the only people who should reply are those who know the answer and are willing to give it.
The Value of JujuScript
In previous post I mentioned that I am creating simple vector graphics games using , even though up until now I have constantly acknowleged that maintaining one’s own scripting language is a waste of time. Well I’d just like to point out that I’ve changed my mind and decided I really don’t feel that way at all, because:
-
Jujuscript has been an incredibly interesting project to work on. I think that creating an interpreter helps in the understanding of programming in general.
-
Contrary to obnoxious comp sci rhetoric, it is not a piece of piss to just whip up your own high level language interpreter. If it was then everyone would be doing it, because it’s not like there aren’t millions of well educated geeks out there with free time on their hands.
-
At least one promising application [so far] began its life as a JujuScript program, and would never have been created otherwise. One of the greatest uses of a script language is for prototyping, and I am yet to come across an equivalently simple object oriented script. If I wasn’t using Jujuscript for such things I would be using nothing.
So I guess what I’m saying is: Jujuscript probably is useless to people in general, being yet another C based language, but to me it is incredibly educational and useful, and even though I am probably the only person who will ever use it, it would be stupid to let it slide.
