MayaFlux 0.1.0: A Digital-Native Substrate for Multimedia Computation

Hello r/cpp folks,

I am very excited to announce the initial release of my new creative multimedia programming framework. Here is a short release text, you can find the full context on the [website](https://mayaflux.org/releases/) or the [git repo](https://github.com/MayaFlux/MayaFlux)

MayaFlux 0.1.0 is a C++20/23 infrastructure built to replace the 1980s-era architectures still underlying modern creative coding tools. Built with 15 years of interdisciplinary practice and DSP engineering, it departs from the "analog metaphors" that have constrained digital creativity since the 1980s. MayaFlux does not simulate oscillators or patch cables; it processes unified numerical streams through lock-free computation graphs.

# The Death of Analog Metaphor

Traditional tools (DAWs, visual patchers) rely on legacy pedagogical metaphors. MayaFlux rejects these in favor of computational logic. In this framework, **audio, visuals, and control data are identical.** Every sample, pixel, and parameter is a double-precision floating-point number. This eliminates the artificial boundaries between domains. A single unit can output audio, trigger GPU compute shaders, and coordinate temporal events in the same processing callback without conversion overhead.

# Technical Core: Lock-Free & Deterministic

Building on C++20, MayaFlux utilizes `atomic_ref` and compare-exchange operations to ensure thread safety without mutexes. You can restructure complex graphs or inject new nodes while audio plays -> no glitches, no dropouts, and no contentions. The state promise ensures every node processes exactly once per cycle, regardless of how many consumers it has, enabling true multi-rate adaptation (Audio, Visual, and Custom rates) within a unified graph.

# Lila: Live C++ via LLVM JIT

One of MayaFlux's most transformative features is the **Lila JIT system**. Utilizing LLVM 21+, Lila allows for full C++20 syntax evaluation (including templates and `constexpr`) in real-time. There is no "application restart" or "compilation wait." You write C++ code, hit evaluate, and hear/see the results within one buffer cycle. Live coding no longer requires switching to a "simpler" interpreted language; you have the full power of the C++ compiler in the hot path.

# Graphics as First-Class Computation

Unlike tools where graphics are a "visualization" afterthought, MayaFlux treats the **Vulkan 1.3** pipeline with the same architectural rigor as audio DSP. The graphics pipeline shares the same lock-free buffer coordination and node-network logic. Whether you are driving vertex displacement via a recursive audio filter or mapping particle turbulence to a high-precision phasor, the data flow is seamless and low-level.

# Temporal Materiality

By utilizing **C++20 Coroutines**, MayaFlux turns Time into a compositional material. Through the `co_await` keyword, developers can suspend logic on sample counts, frame boundaries, or predicates. This eliminates "callback hell" and allows temporal logic to be written exactly how it is imagined: linearly and deterministically.

# Who is it for?

MayaFlux is infrastructure, not an application. It is for:

* **Creative Technologists** hitting the limits of Processing or Max/MSP.
* **Researchers** needing direct buffer access and novel algorithm implementation.
* **Developers** seeking low-level GPU/Audio control without framework-imposed boundaries.

The substrate is ready. Visit **mayaflux.org** to start sculpting data.

# A quick teaser
```cpp
#pragma once
#define MAYASIMPLE
#include "MayaFlux/MayaFlux.hpp"

void settings() {
// Low-latency audio setup
auto& stream = MayaFlux::Config::get_global_stream_info();
stream.sample_rate = 48000;
}

void compose() {

// 1. Create the bell
auto bell = vega.ModalNetwork(
12,
220.0,
ModalNetwork::Spectrum::INHARMONIC)[0]
| Audio;

Are memory leaks that hard to solve?

I have been coding in cpp for the last year (not regularly) and don’t have any professional experience. Why are memory leaks so hard to solve? If we use some basic rules and practices we can avoid them completely.
1) Use smart pointers instead of raw pointers
2) Use RAII, Rule of 5/3/0

I might be missing something but I believe that these rules shouldn’t cause memory related issues (not talking about concurrency issues and data races)

C++ Show and Tell - December 2025

Use this thread to share anything you've written in C++. This includes:

* a tool you've written
* a game you've been working on
* your first non-trivial C++ program

The rules of this thread are very straight forward:

* The project must involve C++ in some way.
* It must be something you (alone or with others) have done.
* Please share a link, if applicable.
* Please post images, if applicable.

If you're working on a C++ library, you can also share new releases or major updates in a dedicated post as before. The line we're drawing is between "written in C++" and "useful for C++ programmers specifically". If you're writing a C++ library or tool for C++ developers, that's something C++ programmers can use and is on-topic for a main submission. It's different if you're just using C++ to implement a generic program that isn't specifically about C++: you're free to share it here, but it wouldn't quite fit as a standalone post.

I built a C++ library for fetching satellite data from N2YO (with Python bindings)

Hello everyone,

I've built a C++ library that wraps N2YO's APIs for fetching satellite TLEs, positions, pass predictions and what satellites are currently above. It can also be built with Python bindings if you prefer.

I hope some of you will find this useful.

Thanks!

C++ examples for use in power system analysis.

I am a mechanical engineer by training, but then chose to do masters and work in energy system management. I work extensively on energy system analysis, capacity expansion planning, power system dispatch simulation, etc. I mainly use Excel, VBA, Python for my work along with the solvers.

I have become increasingly interested on topics of power system analysis including load flow analysis, stability studies, etc. I know that mostly commercial software are used for these kind of analysis, but to a certain extent C++ as well. I am a beginner in using C++. I wanted to check if anyone knows of any resources including tutorials, small projects or courses with use cases of C++ in power system analysis.

A memory effecient TF-IDF exposed via pybind11, to vectorize datasets large than RAM

TF-IDF is a statistical way to find important words in a corpus for NLP projects. However, the standard python libraries are not so well suited if you have low RAM machines.

I tried to redesign some components in C++ using standard libraries/concepts like MMAP, SIMD and fork.

Now, this library can easily process datasets around 100GB (parquet or csv) and beyond on as small as a 4GB memory.

It does have its constraints but the outputs are comparable to standard Python outputs

Hello r/cpp folks,

Why is C/C++ captivating me more than Python?

Hello, I started getting into programming at the beginning of the year, with Python (on the recommendation of a programmer friend), and yes, the language is fine and all that. I also tried JavaScript, but I always had this ‘fear’ of C/C++ because of its syntax and what beginners usually say. But a few weeks ago, I started to get a little tired of Python. A few days ago, I started trying C, and today I wrote my first code in C++. And it's incredible! There will surely be a moment when I want to tear my hair out because it's difficult to understand (especially coming from Python), but seriously, I don't know why it captivates me. Anyway, I'm proud to have taken the plunge :)
