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.

Qt Widgets Rendering Pipeline
https://ossia.io uses widgets and qgraphicsscene for the main UI rendering and Qt rhi for the GPU pipeline, and it's performing well enough for our use-cases - I was working on it on a 1080p screen on a Pi4 recently and it certainly felt much much faster and responsive than chrome on the same hardware.

Is it possible to do runtime compilation and execution of C code?
I use it for live c++ recompilation in https://ossia.io - all the code is in there. https://github.com/ossia/score/tree/master/src/plugins/score-plugin-jit/JitCpp

Show HN: New visual language for teaching kids to code
> I feel like visual programming gets a bad rap because of things like this. As an electronic engineer that used to love LabView and life long user of NI Reaktor and Max/MSP, those tools are fantastic if you don’t approach them with an imperative programming mindset.
aha, in the long run I ended up making https://ossia.io which is as VPL as it can get. Yet it still embeds a LOT of textual languages.

CLion Nova Explodes onto the C and C++ Development Scene
For me both VSCode and CLion lag heavily.. whenver I tried CLion it was completely unuseable on my project https://ossia.io which is only 500kloc (and I try to try it pretty much once a year since it was in beta)
-
Visual Node Graph with ImGui
https://ossia.io does some of it, I've been working on a new release that also supports the whole QtQuick stack in the node graph items but you can already combine videos & shader effects
-
Speed Up C++ Compilation
In https://ossia.io with PCH, using clang, ninja, mold, and some artificial split in shared libraries for development builds, I get a compile-edit-run cycle of a couple seconds in general... I wouldn't say it's too much of a problem if you use the tools already available

Digital Audio Workstation Front End Development Struggles
I develop https://ossia.io with Qt and it works as I want it to
In ossia.io I use three different algorithms / display methods depending on the zoom level used: at "far away" zoom it uses the minmax of the audio slices, at intermediary zoom it draws lines and when getting closer, it starts drawing individual samples.
https://github.com/ossia/score/blob/master/src/plugins/score...
- Automation clips can contain a bunch of bezier curves, which are slow to render.
Convert those to line segments with an approximation setting that looks good enough and it'll be ten times faster (keep the bezier for your data model of course).

- Piano roll clips can contain lots of little rectangles in order to display a "minimap" of the MIDI notes inside of it.
oh damn yes, I spent so much time on this and it still needs so much optimizing... if someone wants to give a shot at it :D

- On top of all this, clips can contain text labels which can also be expensive to render.
Yep, made myself a few "cached text" Qt items over time as the builtin cache wasn't satisfactory
- The fact that a timeline is zoom-able also makes it harder to cache the rendering of clips. If the timeline changed its zoom level, all visible clips pretty much have to redraw all of their contents.
yep
- Piano rolls can also be expensive to render if there is a bunch of MIDI notes, especially if there are text labels on the notes.
yep
- If the user clicks on a folder in a sample browser containing hundreds or even thousands of files, allocating a label widget for each file in the browser list will be very expensive. Something like the list factory in GTK is needed here.
yep, Qt's also able to cache this. Though for instance for Qt's QFileSystemModel I carry a small patch to disable any kind of sorting when there's more than a few hundred thousand files (which happens for large media libraries)
- We want to reserve as much CPU as possible for the actual audio processing. Ideally the GUI shouldn't take up more than one or two CPU threads.

Rack 2 (Virtual Eurorack)
Since some people don’t like the cathedral development style VCV rack uses, I point people to a fork of an older version of VCV rack with two features VCV rack 2 doesn’t have:
* It can run as a VST plugin, so one can use it with their favorite digital audio workstation (DAW)
* The code is BSD licensed
Here is that VST plugin fork: https://github.com/bsp2/VeeSeeVSTRack#downloads

Bespoke Synth 1.0 – open-source software modular synthesizer
* The VST fork of VCVrack for a modular synth: https://github.com/bsp2/VeeSeeVSTRack#downloads
I would get a keyboard controller with full sized keys and a 5-pin DIN MIDI out for just over $200, but that can come later.

Why I'll never create modules for VCV Rack anymore
Actually, for VCV Rack, I personally think most users will be better off using this fork of the code base which is a functional VSTi: https://github.com/bsp2/VeeSeeVSTRack#downloads
Again, I prefer the fork at https://github.com/bsp2/VeeSeeVSTRack#downloads because it’s a working VSTi, and because it’s under a BSD (not GPL) license, which has more flexibility in certain circumstances; I remember the arguments around 2001 or 2002 when there were concerns Python’s license was not “GPL compatible”, so I have always found GPL licenses pedantic.
I like this one: https://github.com/bsp2/VeeSeeVSTRack#downloads It has the old BSD VCVrack license, but it still has source code as well as Linux and Windows binaries.

If you are interested in experimenting with modular synthesis, check out VCV Rack. It's an Eurorack simulator with a huge number of modules, many of which are open source.
Omri Cohen recently hosted the Mycelium Symposium where many creators showed some interesting possibilities using VCV Rack.
