teepee: Finished. Caterpillar is up as number 22.
<JordanBrown[m]>
InPhase: Looks like the readme is stale, might want to update it.
<JordanBrown[m]>
Looks good, but you might want to make the treads be a different color; they disappear into the background.
<JordanBrown[m]>
My first reaction seeing the "1975" was "boy, he was young", and then I do the math and come up with 47. Which is still young, but not nearly as young as 1975 seems like it should be. I'm getting so very old...
<InPhase>
Yeah, I had a similar reaction to 1975.
<InPhase>
And I didn't want to alter the treads, because those are the colors from the original. I left the design completely intact from his model, just rearranged the code for it.
<JordanBrown[m]>
Ah, got it. Makes sense. Maybe change the background instead. We can survive having it have a different background.
<InPhase>
I also need a darker background for the ending sequence.
<JordanBrown[m]>
Hmm. Maybe just a little lighter, so it's still dark but is lighter than the treads?
<JordanBrown[m]>
I feel honored that my Santa is in the 24 slot.
<JordanBrown[m]>
But I have to agree that it's appropriate.

<InPhase>
Alright. Trying again with an in-between color.
<InPhase>
And done.
<InPhase>
Now trying some sleep.
<InPhase>
(And, thanks for the tip. It was a correct change, I just got used to looking at it by the time I finished.)
ur5us has quit [Quit: Leaving]
<JordanBrown[m]>
Yes, looks good.
<JordanBrown[m]>
G'nite.
<JordanBrown[m]>
Interesting. I happened to have left a copy of the original on my screen, and it surprised me because the treads were visible. Looking more carefully, if I move it to my left monitor they are visible (albeit still close to the background) but on the right monitor they're invisible. Must be a difference in the brightness of the monitors, or something. But the new version is better.

did we know what happened to justin?
<JordanBrown[m]>
The one reference I saw just said "illness".
<JordanBrown[m]>
but for me Google Translate wants to translate from German, so I have to explicitly tell it "detect language".
<JordanBrown[m]>
And for whatever reason it won't let me select text off the translated page.

A well-known technical writer and columnist for iThome. Lin Xinliang, known for his "Lianggege Study Notes" (openhome.cc), is a well-known technical writer and translator in Taiwan, as well as an iThome columnist. Passed away due to illness in 2022 at the age of 48.

teepee: Morning. If you need to run that manual calendar update step you spoke about, everything is in place now for the full calendar.
<teepee>
\o/
<teepee>
awesome
<teepee>
I'll update once I'm done with the invoices stuff
<InPhase>
Ok. :)
<InPhase>
Something appears amiss with the Track.png in the readme listing, but it's also working fine on the calendar, so I wasn't able to figure that one out.

yeah, no idea what's going on with that. I tried reencoding but it did not help. it does not work on github with firefox, but it does work with chrome
<teepee>
InPhase: I've added a note with some links. could you please review that?
<InPhase>
On the animation, I was going for a "the work lives on" symbolism at the end, leaving the mechanical bit behind. I figure what else can a programmer ask for.
<JordanBrown[m]>
"Todays" -> "Today's"
<JordanBrown[m]>
Comma after "Lin".
<InPhase>
Oh, yes.
<JordanBrown[m]>
Maybe "We'd like to commemorate" -> "It commemorates"
<InPhase>
I prefer the "We'd like to".
<InPhase>
Active, and it expresses community behind it.
<JordanBrown[m]>
OK
<InPhase>
That design was also the first time I made use of that smoother_step function peepsalot taught me about for a trajectory. I realized it lined up well with what a skilled driver would do for that sort of path.
<teepee>
updated
<InPhase>
Also, I want to note that this overall appears to me to be a really impressive calendar. It's quite a collection of impressive looking stuff and demonstrations with all the doors open.
<teepee>
Yep, I totally agree. And also a huge thanks to J221160 for getting things half way by November. It would have been a massive struggle otherwise
<InPhase>
The first one in 2019 was pretty special, because it was the first, and we managed to pack in every Christmas themed thing we could think of. But this one is by far the most impressive aggregated collection to my assessment.
<J221160>
Ü
<InPhase>
And the sheer amount of technological diversity of what is demonstrated on a single calendar here is pretty off the charts.
<InPhase>
We have fractals and chaos theory, cellular automata with life, copious amounts of recursion for shape design demonstrated in a wide variety of forms. Piles of different animations. Procedural generation. Lots of fancy visual-effects methods displayed. Excellent use of color throughout. And a wide-assortment of methods suitable for a tips and tricks list. :)
<InPhase>
I think in part we might all be a lot better at this than we were 3 years ago, perhaps due in large part to the feedback cycles of trying to make these calendars.
<InPhase>
Back in 2016 when I first got into 3D printing, I gathered some images into my mind of what sorts of things OpenSCAD is good at. And it looks like this calendar was made with a completely different program.
<teepee>
:)
<InPhase>
Also... after 2 weeks, to my knowledge no protests have been filed about the fluid dynamics in Bubble Trap being a cheap optical illusion. So I might have gotten away with this trickery. ;)
<InPhase>
The dark blue sphere in fact does not even move within the bubble.
<teepee>
I really hope people come to their senses at some point.
<teepee>
In related news, Bre, there's a name I have not heard for years ;-)
J221160 is now known as J22
<J22>
i am sure in 5 years we have some AI that build nice openSCAD advent calendar
<teepee>
I don't know. My prediction is that's not happening
<J22>
(with palm and minerva we probably already have them - but not public)
<teepee>
I guess we'll see once the stuff is actually public. Till then I'm rating that along with the Tesla "self driving" - you can summon your car across US in 2019
<J22>
and a Chrismas tree arrives to pick you up
<InPhase>
teepee: Hey! That sure beats all the Christmas trees chatgpt made for me.
<J22>
at least self driving taxi are already in service
<teepee>
true, but I'm not sure how much AI is in those
<teepee>
the Tesla robo taxis (what was that 1 million on the streets in 2019) are certainly not
<teepee>
I've seen a video where the old Tesla self parking did nicely where the new AI one just failed in spectacular way
<J22>
i saw a sterling engine .. which first looked shitty but it turns out it put the cylinder correctly together (more or less) but just not with differences so it became just a union
<J22>
about recipe - first i thought it was only for cooking .. then it turns out it can do all sort of chemicals ( glue poison explosives (then my account was suspended) )
<teepee>
lol
<J22>
and it can give you instructions for everything .. maybe even building an ikea shelf

yeah, that's probably the new template system
<teepee>
nice to have an example how that works
<J22>
after you choose you get a nice form to fill with version OS and text fields for action result expected result to fill out (* can't save without filling certain fields)
<teepee>
yep, I've looked at the documentation some time ago, it seems quite useful
<teepee>
IIRC it can also attach labels directly
<J22>
it does .. mine got "triage" and "bug" Ü
<InPhase>
I really like that support for "Have questions or need support?"
<InPhase>
J22: Those sorts of behaviors are non-trivial to put into automated testing.
<InPhase>
You pick one, and you can write a test check for it. But then there can be another just as bad that the test can't spot.
<J22>
Ok but if any developer is also 3D printing (and using cura) he should spot these .. all my prints have this since i used the 5 version
<teepee>
I've not seen that (using the beta version) so it might be some settings combination
<teepee>
and cura certainly has lots of those :)
<J22>
and i customize ALL of them
<teepee>
I've changed a number of them, specifically for convincing it to not do crazy back and forth path for a simple box
<J22>
if using .01 more line diameter the amount of bad travel reduces to 10%
<teepee>
for some reason in some settings it changes direction for every loop which creates annoing artifacts
<teepee>
and slows down quite a bit
<teepee>
does it happen if you disable the "randomize layer change"?
<J22>
that direction change is a good thing .. i wish that could be set for vase prints .. i got very different results for twisted objects if you print the mirror version
<J22>
without randomize there are also less but for some reason he chooses to start the other walls on the other side - and need to travel there • the problem is that combining fails and the nozzle is not keept within the print
<J22>
best result is "user specific" but also there are a few left
