T * sin (t)' ≈ Ornamented Christmas Tree (2013)
- ryeguy_24 2y agoMerry Christmas HN. Ever year, the original T * sin(t) Christmas tree gets posted. This year, I wanted to call out my favorite modification by Silvia Hao. It’s beautiful. One year, I’ll try to add to its beauty. But for now, I’ll just appreciate it. She posted it here: https://community.wolfram.com/groups/-/m/t/175891 https://community.wolfram.com/groups/-/m/t/175891
- Arnavion 2y agoSilvia Hao's version is the one submitted here to HN, actually.
- dylan604 2y agoSomeone was too excited about Santa to actually you know click the link
- frogulis 2y agoThe GP commenter (ryeguy_24) is the original poster of this article, leaving additional information about what they posted.
- dylan604 2y agoYeah, and? That was the link that was not clicked. If the person had clicked that link they would have seen why their comment was not helpful.
- flaminHotSpeedo 2y agoI think you still misunderstood. ryeguy_24 was *commenting on their own post* They obviously clicked the link, because they posted it.
- dylan604 2y agoYou still think my comment was about ryeguy instead of the person I replied which is typically how comments flow. If they had clicked the link and read it, they would have seen why ryeguy posted the link that shows the evolution from the ‘original’. I’m really not sure why we’re unable here To the point, they even admitted “guilty as charged”. I mean, what’s the cause of the lack of comprehension?
- Arnavion 2y agoTo beat this dead horse some more, I *had* clicked the link (how else would I know it was Silvia Hao's version that had been submitted?) and *had* read the username of the commenter of https://news.ycombinator.com/item?id=42506146 https://news.ycombinator.com/item?id=42506146. What I had *not* read was the username of the submitter, and thus did not realize the commenter and submitter were the same person, which recontextualizes the comment in question from "Personally my favorite version is Silvia Hao's that can be found in this discussion thread" to "This image that I submitted is by Silvia Hao and can be found in this discussion thread".
- acer4666 2y agoSome was too excited about Santa to, you know, read the usernames of the submitter and commenter
- TheSpiceIsLife 2y agoSome kind of Pareto Principle: 80% of people read 20% of the usernames.
- deskr 2y agoWrong. It says that 20% of people will argue with you and be confident that they are right even though they are more wrong.
- romanobro56 2y agoPareto victim right here
- JadeNB 2y ago> Pareto victim right here I'm pretty sure deskr was making a joke.
- TheSpiceIsLife 2y agoI chuckled
- TheSpiceIsLife 2y ago100% of the people I live with will argue with me 20% of the time and be wrong 80% of those times.
- Arnavion 2y agoGuilty as charged.
- JadeNB 2y agoI checked the post, but it's from someone who's far more comfortable with Mathematica than I am, so I hope you won't mind my asking about the maths. First, the T vs. t in T * sin(t) doesn't mean anything, right? Second, the ' in the title T * sin(t)' doesn't belong, right? Then I think that this is graphing essentially (t * sin(t), t * cos(t), t + something), which is a cone if the something is constant, which I believe it is—and that certainly matches the graph. And the rest is about choosing an aesthetically pleasing step size and accomplishing the lovely twinkling and colors, right?
- layer8 2y agoOr a drill.
- block_dagger 2y agoThis is not a drill. It really is Christmas.
- layer8 2y agoThe function is neither a drill nor a Christmas tree, but similar to how it happens to look (≈) like a Christmas tree, it also happens to look like a drill. This is what I wanted to point out. It’s a multipurpose function.
- DrSAR 2y agoIt is also not a pipe
- arcticbull 2y agoCici n'est pas un arbre de Noël tabarnak
- bjconlan 2y agoHaha, oh I miss the Quebecois. Appropriation of Catholic vernacular make for the best profanities.
- Uncorrelated 2y agoblock_dagger was making a pun based on the sense of drill as a training exercise. A similar joke went over the heads of nearly everyone on a recent episode of Taskmaster: https://www.youtube.com/watch?v=6PJkA3o_Im0 https://www.youtube.com/watch?v=6PJkA3o_Im0

- noduerme 2y agoI went to Hopscotch in Portland with some friends tonight, tried out the "quantum trampoline" [0]... spent most of my time in socks wondering if that was written in plain ol' javascript or p5.

- capitainenemo 2y agoWell, they do have a github.. https://github.com/kuflex https://github.com/kuflex Looks like it was written in C++
- foobar1962 2y agoMy first time seeing it. Thanks for posting, and thanks to HN for being the kind of place that stuff like this gets posted.
- Alifatisk 2y agoI think this would be perfect on openprocessing.org, I just don't know how to implement that.
