<Guest36> Hello all
<Guest36> is there anyone interested in new Iris Dome Box?
<Guest36> Like Emmett's design
<Guest36> but this one has 6 leaves. and does not have in-situ printability.
<Mattlau[m]> Hello, i'm new to OpenSCAD, and i'm currently trying to space a few cylinders evenly along a line... (full message at <https://libera.ems.host/_matrix/media/v3/download/libera.chat/3529f79f499dfcddbf98d269c1e0a33593d83cd4>)
<teepee> Mattlau[m]: there's 2 go-to solutions for that, either calculate the cummulative sum first
<teepee> or using a recursive call collecting the relative translations
<teepee> I do hope array slicing will happen at some point, I wrote code for it some time ago :)
<teepee> actually there's a 3rd option if you don't mind living on the bleeding edge of applications :)
<Mattlau[m]> Slicing would be very nice indeed, OpenSCAD seems really nice so far, but the langage itself is quite barebone
<Mattlau[m]> > actually there's a 3rd option if you don't mind living on the bleeding edge of applications :)
<Mattlau[m]> I *love* living on the bleeding edge, what is it?
<teepee> someone working on allowing the use of python
<Mattlau[m]> making OpenCAD a superset of python synthax?
<Mattlau[m]> s/OpenCAD/OpenSCAD/
<teepee> so it's not fully integrated and it obivoulsy is running python code that can do anything on your system :)
<teepee> no, basically allwoing to use either openscad language as it is or using actualy python
<Mattlau[m]> sounds really nice, do you have a link?
<teepee> the change is on the way to the official nightly builds, mostly slowed down by me not having not a whole lot of time right now
<teepee> that's guso78 here if you want to give that a try
<Mattlau[m]> i see, thanks a lot for the help!
<Mattlau[m]> I'll give the python fork a try, seems far more convenient for my use case
<teepee> oh, the cumulative sum is easy to solve, there's libraries :)
<teepee> but considering you already shared python stlye code ...

<teepee> fwiw, the PR is https://github.com/openscad/openscad/pull/4702 but the automatic builds don't have python active yet, so it would need self-compiling still
<Mattlau[m]> oh, i didn't even see there were automatic builds, i jumped straight to building x)
<teepee> :)

<othx> Guest36 linked to "6-leaf Iris Dome Box (Pollen) by Oneeyedgear" on thingiverse => 1 IRC mentions
<Guest36> for those of you who are interested in 3D printing
<Guest36> have fun :-)
<Guest36> and I'd be happy if you give me feed back
<Guest36> find me on the links I mentioned
<Guest36> have a nice day
<Guest36> or night
<Guest36> wherever u are ;-)

<InPhase> "Notice_3: assembling the leaves is the most challenging part of the assembly process so, don’t give up on it soon." and then, he gives no instructions?
<InPhase> That's a lot of parts to bother printing with no certainty that it will go together.
<teepee> oh, yeah, instructions would be nice. also a nice title picture
<InPhase> There's the instagram link in the description which shows it functioning, but it's much better thingiverse salespitching to have a title picture embedded showing what the result will be. (Plus instructions)
<InPhase> I clicked on it and thought "That's a bowl not an iris, is this mislabeled?" before I figured out what was happening.
<InPhase> We should probably let Guest36 know if he ever returns long enough for actual feedback.
<teepee> yep
* teepee was a bit distracted ordering a huge box of spices and stuff
<InPhase> A worthy endeavor.
<teepee> indeed, promised to buy some of the stuff for others for month now :)
<teepee> but I'm finally running out of multiple things, so no way of pushing that out further
<teepee> wow, someone was busy https://chriscombs.net/
<InPhase> Hahah. I suspect kids would love this thing. https://chriscombs.net/2023/04/13/this-machine-hates-kids/
<teepee> yes, that's probably fun if you are in a bigger group, looking who gets the alarm
<InPhase> I guess in the modern world you're never too young to learn about racial bias in training sets...
<teepee> concern is if there's anything done about it, to actually fix those problems

<Guest24> Hey everyone Abhishek here does anyone have any idea that will BRL CAD appear for gsoc 24
<teepee> we did not even finish gsoc-23 :)
<Guest24> Oh damn im sorry haha
<teepee> we can't really tell if BRL-CAD will apply again, I suppose we'll try again
<teepee> but then we also need to see if Google actually continues the program, I assume they do
<Guest24> The thing is I've been getting into open source just now so thought of asking
<Guest24> Cool cool thanks
<Guest24> Are you part of gsoc 23 teepee?
<teepee> yes, I'm mentor for our project
<Guest24> Oh that's great
<Guest24> Is there any way I can reach out to you personally I have some doubts
<teepee> what for? I don't see any need to share personal information at this point, everything else is fine here
<teepee> open source development usually also has the discussions in the open so people can follow that if they want
<Guest24> Yupp sure, got it.
<teepee> for brl-cad, you should join their Zulip chat. We here are OpenSCAD which is a different CAD application.
<teepee> BRL-CAD hosts a number of different applications / teams for GSoC
<Guest24> oh so OpenSCAD is a part of BRL-CAD?
<teepee> no, it's 2 different open source CAD applications and teams
<teepee> but working together as a group of CAD applications for GSoC
<Guest24> is openscad not listed as a GSOC organistaion because i am unable to find it
<Guest24> i only see BRL CAD on the official webpage
<teepee> yep, BRL-CAD is the so called "Umbrella organisation" - the one directly talking with Google about GSoC
<teepee> but this umbrella means there's other projects / organisations taking part via that too, this years list you can see at https://opencax.github.io/
<teepee> you can find those in the description of the BRL-CAD entry on the GSoC site
<Guest24> Yupp found it thanks
<Guest24> If you dont mind me asking, how many slots were available for openscad this year? or for the umbrella organization in total
<teepee> I don't know how many we *could* have received. considering BRL-CAD is in the program for many years, we likely could have asked for quite a number of slots
<teepee> but all the projects combined tend to not get a huge amount of applications due to CAD being special and a number of projects being C++ or so
<teepee> in the 6 or so years we took part we as OpenSCAD had somewhere between 1 and 3 projects, and 2 years with 0
<teepee> brl-cad as umbrealla, I don't really remember and also the number of projects taking part changed over time
<teepee> but it certainly was > 10 at times
<teepee> still far way from some of the huge projects like KDE and Python :)
<Guest24> yupp well KDE is in a decline now the number of projects has been steadily decreasing
<Guest24> well thanks for all that information teepee
<teepee> so if you want to take part in 2024, my advice is:
<teepee> 1) check somehere around November if Google announces if they continue the program
<teepee> 2) get involved latest beginning of next year, a bit before the official action starts
<teepee> plus, consider the most important part is talking to people :)
<Guest24> is there a chance google might dicontinue the GSoC program? are they planning to do so?
<teepee> there's always the possibility, but I'm not seeing any indications that they plan to do so
<teepee> they do ask for feedback and opportunities for changes and improvements which sounds more like a continuation is wanted
<Guest24> thats great
<Guest24> can you give me some advice on how to choose the right organisation?
<Guest24> is choosing the one with more projects better?
<teepee> the only thing I have to say in that regard is: find something where you actually have some interested and motivation
<teepee> gsoc is not just about churning out code in a defined time span
<teepee> it's meant to introduce people to open source projects
<teepee> showing how it can work with people across the world trying together to create something useful
<teepee> maybe even ideally having the people stick around after gsoc
<teepee> I know a couple of examples where people became mentors a couple of years after they joined as students
<Guest24> Yup that is true. But the thing is i am from India belonging to a poor economical background, so i just want to increase my chances of getting selected in the GSoC program.
<Guest24> that is why I asked as the stipend would really help me
<teepee> I understand and that's probably not even a rare case. It does not change the recommendations though. in most cases the people of the open source projects who will review your application are doing that work in their spare time
<teepee> and they are looking for "contributors" to the project, not "workers"

<Friithian> I was about to start modeling something in openscad but it's hard to replicate a real life object in digital space without proper measuring tools… anyone spare me a pair of calipers?
<InPhase> Friithian: Yeah, it's a mandatory investment for good precision work. Also you want a professional grade ruler. I can link the ones I got for this.
<Friithian> I have a pcb ruler :D but if you have a link to nice calipers that wont make my head explode due to price I'd love a link
<teepee> 7.99€ on amazon, cheaper than twitter for a month :D
fling has quit [Remote host closed the connection]
<Friithian> whomst the fuck is paying for twitter
fling has joined #openscad
<teepee> too many people
<Friithian> yeah it's weird and sad
<InPhase> Friithian: So this sort of ruler is pretty superb. You have extremely accurate measurement right up to the edge, and being stainless steel you're not going to get deviations from this over time without some truly serious abuse of it. https://www.amazon.com/gp/product/B00LYAJRAO
<teepee> ah, I do like the metal ones
<InPhase> Still digging out the caliper. It might be out of stock... Ah, there it is. This is the unit, but it slipped out of prime shipping for the moment. https://www.amazon.com/Oumij1-Electronic-Protection-Fractional-Measurements/dp/B087LS6HCL/
<InPhase> There are plenty of other ones available.
<InPhase> But basically you should be able to get 0.02mm accuracy for $35 or less.
<Friithian> for reference I am trying to model one of these https://www.peakdesign.com/products/standard-plate-v3 but with a cold shoe instead of 1/4 20 screw stuff
<Friithian> 0.02mm accuracy is more than any 3d printer I can get can do :P
<InPhase> This looks like it comes out of the same factory, but they use a prettier blue plastic in the same mold for this one. And it has prime shipping. https://www.amazon.com/Kynup-Measuring-Stainless-Waterproof-Protection/dp/B07X8JQ8L5
<InPhase> Friithian: So you might think, given the 0.4mm extruder nozzle. But in reality changes to your model will affect sizing down well below the nozzle size, and this can impact tight fitting mechanical parts significantly.
<Friithian> well, tbh I need a 3d printer that works before I can print anything :P
<InPhase> So while I mostly pay attention at the 0.1mm scale, there are some cases where I pay a little bit of attention to the next digit. :)
<Friithian> tolerance for this should be very forgiving, I'm only attaching a remove trigger to it so it isn't like it is holding an expensive camera or anything
