#2Site does not render without JS enabled. At all. You get a flat white page. Enabling JS lets it render, but also scrolls crippling slowly. If I could downvote right now I would.
But it gets worse.
Nothing in here is about graph theory. It is a massive over complication. He is just trying to resize to a new aspect ratio by cropping the least amount. While dragging in calculus? This is really very simple and common. Imagemagick even has a dedicated option for it:
-resize ^ -gravity center -extent
To add insult to injury, he then uses Imagemagick to do the resize! The article is misleading, poorly written and hosted on a horrible platform to boot.

#3Not, by any stretch, remotely, anything to do with graph theory. If you're mathematically inclined, you might call the techniques used 'linear algebra', but even the non-mathematically inclined will probably have encountered them in school as just plain 'algebra'. And most people could solve this problem without symbol manipulation by just drawing themselves a couple of pictures and doing basic arithmetic.

#4See I don't mean to be defensive here, but it's the first post. Might not be too constructive knowledge-wise, but it would be appreciated if you could point out the mistakes politely. I guess this is what this forum is about. I agree the topic name is named inappropriately, would be corrected soon.
