Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Show HN: Flyde – an open-source visual programming language
As a visual person (traditionally trained as a graphic artist), I've wanted this sort of thing for a long while, and I've been trying to use it for 3D.
Surprisingly, there are multiple specialized tools for this:
- https://www.blockscad3d.com --- an adaptation of Google's Blockly to OpenSCAD
- https://github.com/derkork/openscad-graph-editor --- wires and nodes, it has the advantage of exposing _all_ of OpenSCAD's commands (the above has a subset)
- https://github.com/Tanneguydv/Pythonocc-nodes-for-Ryven --- a module for using PythonOCC in Ryven --- when I finally succeeded, I found the language inscrutable, even when provided w/ quite nice examples (definitely a failing on my part, not that of the tool)
- https://github.com/graphscad/graphscad --- it took a long while for the source code for this to be made available, and for a while it had compatibility problems (why was "cube" redefined?) --- probably defunct for political reasons, it had some interesting ideas, in particular the ability to have custom icons for modules
- https://www.nodebox.net --- if memory serves I got hung up by not easily being able to do 3D, and when doing 2D having precision problems (or maybe that was Processing.org)
and I've been using these tools to make various things:
https://willadams.gitbook.io/design-into-3d/3d-project
(and maybe eventually I'll finish something)
The problem I've been running into is there doesn't seem to be an answer to the question:
"What does an algorithm look like?"
I recently had occasion to mention Herman Hesse's _The Glass Bead Game_ (also published as _Magister Ludi_) and I'll bring it up again --- what is a meaningful graphical representation of a program?
The Drakon folks argued that there should be one true path but that's not really communicative and I would note that if this was a simple thing it wouldn't be decades since I last saw a physical Flowcharting Template:
https://americanhistory.si.edu/collections/object-groups/flo...
(and it's pretty rare to even see a well-done electronic drawing of a flowchart since Visio made its splash and vanished into the bowels of Microsoft)
The main problem seems to be one of expressiveness not scaling up well, hence:
https://blueprintsfromhell.tumblr.com/
https://scriptsofanotherdimension.tumblr.com/
Presumably, one doesn't want to define modules/variables unnecessarily --- but the question becomes where is that boundary?
If you define too many, then you're back to the "wall of text" which one was trying to avoid (but wrapped up in nice boxes with some lines or shapes), and if one doesn't use them (well, look at the pretty/awful images in the links above).
Ideally, a well-coded visual program would have a pleasing aesthetic appearance which is expressive and communicates flow and function, and I've tried for that at:
https://willadams.gitbook.io/design-into-3d/programming
(though I wish that there was an easy way to export an SVG version of a program)
I believe that what is needed here is some graphical equivalent to Literate Programming: http://literateprogramming.com
Is there a nice GUI toolkit integration which would allow making a graphical application with this? I have an idea I want to try it which might be a good fit.
- Parametric for the win... until it isn't.

Ask HN: Visualizing software designs, especially of large systems (if at all)?
"What does an algorithm look like?"
I'm an intensely visual person, but have never found a visual programming system which scales well --- the problem is, past a certain level of complexity one has to use modules, which then devolves the visual representation down to just a bunch named blocks.
That said, I'm using BlockSCAD:
https://www.blockscad3d.com/community/projects/1421975
to work up designs which I'm then putting into other tools.
Looking at GraphSCAD:
http://graphscad.blogspot.com
and there's also Ryven and pythonocc which I managed to get installed:
https://ryven.org
https://github.com/Tanneguydv/Pythonocc-nodes-for-Ryven
but I'd really like to see a tool for this sort of thing which made G-code.
- Finally managed to get PythonOCC Nodes for Ryven installed (on Windows --- will have to try again for Ubuntu) --- here are my notes
- What is the one feature that would get you to try a new CAD software?

Ask HN: Modern Day Equivalent to HyperCard?
I really wish Livecode hadn't pulled their opensource/Community Edition (and I'd be very glad for someone to do something with that code).
Gambas is something I keep wanting to try and seems promising.
I did one small app w/ Python and TKinter, but it was a dense wall of text/code when I was finished and not something I was interested in revisiting. I keep seeing suggestions that Python w/ QT support is supposed to be quite good.
One unlikely option is Google's Blockly (which I wish had a stand-alone desktop implementation which would make graphical programs), which has a nifty version implementing OpenSCAD:
https://www.blockscad3d.com/editor/
which I've used a fair bit. Moving on from there, there is: https://github.com/derkork/openscad-graph-editor which has the advantage of encompassing the entirety of OpenSCAD. It's also possible to wrap up Python using PythonSCAD.org
If you're willing to consider other node/line connection systems two promising options are:
https://ryven.org/
and
https://nodezator.com/
What sort of coding, on what sort of projects do you want to do?

Standardized, Python based Block Diagram File Format for Dynamic Modeling as an Open Source Alternative to Matlab and Simulink
There are general visual programming tools for python like ryven or PyFlow that should be able to run generic code, so in theory you can put SimuPy code in the blocks.

PyFlow – a tool for visual and modular block programming in Python
Why this over https://ryven.org/ ?

PyFlow – Visual scripting framework for Python – NodeRED alternative?
Interesting, came across https://ryven.org/ recently which looks in the same domain.
Any practical use cases of either being used?
Huge fan of NodeRED, always thought the paradigm could be leveraged for other heavy workflow applications

Blender + Ryven; leveraging the power of node editors in Blender by building on top of an open Python-based framework
I'm developing Ryven (https://ryven.org), a python-based visual nodes editor/platform. I recently published a tiny prototype plugin for Ryven 3.1 inside Blender (https://github.com/leon-thomm/ryven-blender). As Ryven is Python-based and quite easy to use, and Blender already had success with an integrated nodes editor, I would like to find out whether based on Blender's Python API it'd be possible to develop a large, powerful, compatible, and easily extensible framework of nodes for Blender that run on Ryven.
