Beginning of this week I worked on an implementation of the Quickhull algorithm, which can be used to compute the convex hull of a set of points. Incredibly useful for real-life problems, but I have yet to find a use for it in my creative coding. I summarized the required steps to implement the algo in this post: [Quickhull Algorithm for Convex HullsOne method for finding the convex hull of a point set is the Quickhull algorithm. It makes use of the divide and conquer paradigm, and builds the convex hull in a recursive manner. This post is a break-down of a Quickhull implementation.![](https://storage.ghost.io/c/e8/51/e851bb8f-1e95-43e1-83eb-1b6ae9a0791c/content/images/size/w256h256/2023/03/icon-1.png)Gorilla SunAhmad Moussa![](https://storage.ghost.io/c/e8/51/e851bb8f-1e95-43e1-83eb-1b6ae9a0791c/content/images/2023/04/banner-2-.jpg)](https://www.gorillasun.de/blog/quickhull-algorithm-for-convex-hulls/) > Implemented the Quickhull algo.

I also finally found the time to have a look at the open-sourced Twitter code, which I've been meanign to do for a while. It's fascinating to see how a modern social media platform like Twitter operates behind the scenes. It is also interesting to discuss how such an algorithmic pipeline influences free speech on the platform, and if it is even possible to have completely untainted freedom of speech in that manner: > New post is up on the Blog! 🔖 This time around we'll inspect the Twitter algorithm, and see what it does behind the scenes! > > 🤫 Don't tell Twitter, but the link is in the replies...

I continued working on this sketch of mine. I took the grid based contour walk code that I implemented two weeks ago and patched it in, and am now able to determine individual Tetris-like regions, rather than just the illusion of segmented regions that was previously made by filling the grid in with rectangles. I'm pretty happy with this generative system so far, and I think I can now start working on some textures and fill experiment with fillin out the different regions with patterns. > Probably doesn't look like much in comparison to the previous version -- however, now each individual region is it's own polygon -- in contrast to before where it was just a bunch of rectangles!

Up until now I have been under the impression that one should be active on as many social media platforms as possible to maximize one's growth. However, now I'm coming around to thinking that this might not be so, and might actually be counter productive in the larger scheme of things, and might in a way even stifle your goals. I recently read this post on creator science by Jay Clouse, he writes: > \[...\] – we're all competing for a finite amount of global attention. And there are people who are putting way more time and effort into learning the ins and outs of that game – that's why they're winning! [The game within the game (why your growth may be slow)The fastest way to build an audience is to focus on doing one platform really well. I am absolutely convinced of this.

The controversy on AI generated imagery continues. Last week we observe an AI generated image win the Sony World Photography prize. The photographer says that he did it to provoke debate.

[An A.I.-Generated Picture Won an Art Prize. Artists Aren’t Happy.“I won, and I didn’t break any rules,” the artwork’s creator says.![](https://www.nytimes.com/vi-assets/static-assets/ios-ipad-144x144-28865b72953380a40aa43318108876cb.png)The New York TimesBy![](https://static01.nyt.com/images/2022/09/01/business/00roose-1/00roose-1-facebookJumbo.jpg)](https://www.nytimes.com/2022/09/02/technology/ai-artificial-intelligence-artists.html?ref=gorillasun.de) I would argue that the issue could potentially be solved by opening a new separate category for AI generated art, and put in place a meaningful method to judge and compare these submissions fairly. In the case of the photography contest, I'm not certain how much this stunt actually pushes the debate forward, except that better measures need to be put in place to avoid such deceptive attempts in the future. By analogy, this makes me wonder where the line falls regarding photoshop and the post-processing of images. Because technically, one could edit their photos at an atomic pixel-level and essentially reshape an image from the ground up into something completely different... how different is that from using a neural network to upsample these pixels? The problematic that emerges here, is that I don't really see an obvious way in which these images could be judged. It would take a jury that has some technical know how, or is at least to some extent acquainted with the tech, to adequately judge these submissions. But then again, I don't know how subjective the final verdicts of these contests generally are after all. 1. Amy Goodchild with another banger article on her blog.

One thing I have struggled with since I started with the blog was how to efficiently serve the images in my posts. Some of my posts have a large number of them in addition to GIFs and videos, hence it can quickly add up and slow down the overall page load speed. Nowadays I try to avoid the lossless PNG format and use JPEGs wherever I can, but there's an even better way to save on bandwidth, and that's the html srcset property: [Responsive images - Learn web development | MDNThat’s a wrap for responsive images — we hope you enjoyed playing with these new techniques.
