Merry 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
I 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?
I 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. Happy Holidays, folks.
The 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.
block_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:

Silvia Hao's version is the one submitted here to HN, actually.
Someone was too excited about Santa to actually you know click the link
The GP commenter (ryeguy_24) is the original poster of this article, leaving additional information about what they posted.
Some was too excited about Santa to, you know, read the usernames of the submitter and commenter
Guilty as charged.
Some kind of Pareto Principle: 80% of people read 20% of the usernames.
Wrong. It says that 20% of people will argue with you and be confident that they are right even though they are more wrong.
100% of the people I live with will argue with me 20% of the time and be wrong 80% of those times.
Pareto victim right here

I'm pretty sure deskr was making a joke.
I chuckled

I added the prime in the title to indicate that this version is a bit different from the original t * sin(t) post.
OK, thanks. Is the rest of it right?
That's a beautiful animation (and useful maths ;-).
In the spirit of minimalism, Merry Christmas to all HNers with this little but time-tested command:

with u(t) is called 60 times per second. t: elapsed time in seconds. c: A 1920x1080 canvas. x: A 2D context for that canvas. S: Math.sin C: Math.cosMy first time seeing it. Thanks for posting, and thanks to HN for being the kind of place that stuff like this gets posted.

I think this would be perfect on openprocessing.org, I just don't know how to implement that.
Now make 30% of the bulbs randomly burn out :)
Randomly wouldn't be that bad. But whole segments - way more noticable!
usually a bunch of lights are wired in series, if one burns out all stay dark.
Find and replace the broken one, and all light again!
Or a drill.
This is not a drill. It really is Christmas.

English being the global language makes it easier to get a lift, but much harder for anyone to pick you up.
It is also not a pipe
Cici n'est pas un arbre de Noël tabarnak
Haha, oh I miss the Quebecois. Appropriation of Catholic vernacular make for the best profanities.
I wish I had more to add, but I do not. This proper tickled me, thank you. lmao
