Which smartphone OS should I use?

I have been looking to move away from my android and have been looking into opensource OS such as GrapheneOS and others.

While LegacyOS supports many phone models, they are still out of budget. I have a VIVO V2027 phone lying around. Which opensource OS can I use with it? Can I install the OS as it is on the phone that current has android on it? Or does it need some other specifications?

Would like some help with this. Thanks

Open-source security tooling: what monetization models stay community-friendly (open-core vs dual license vs services

I’m building an open-source runtime security tool and trying to design a sustainable business model without pulling the rug on indie users.

Constraints that matter to me:

Explanations over “magic scores” (teach devs why something is flagged)
Runs offline/on-device (CPU/edge), so sensitive data doesn’t have to leave the environment

I’m exploring: paid support/training, enterprise packaging (SSO/RBAC/audit/compliance), and/or dual licensing.

Questions for folks who’ve done this well

1. What models have you seen work that don’t “enshittify” the community edition?
2. If you did open-core, what did you keep paid without backlash?
3. If dual-licensing: how did you handle contributors + CLAs and avoid future pain?
4. Any “landmines” you wish you knew early?

(Not linking anything here—happy to share details if someone asks.)

I built a Python-native rendering framework with JIT CSS and State Management that lets you manipulate templates as Python objects. also usable with django

Hey everyone,

I wanted to share a project I’ve finished working on past 5 days, called Mastodon UI (mui in short).

I'm Django-oriented as one of my backend stacks, I love its backend features like (ORM, Forms, Auth), but I’ve always found the template system to be a bit of a context switch. I’d be writing complex business logic in Python, then have to jump into an HTML file to write Jinja-style loops and conditionals. I missed the type safety and autocomplete, and the OOP capabilities I had in my Python files. so I decided to build a middle ground: A Python-native template rendering framework in Python that can be a meta-framework for Django.


It’s called Mastodon UI, and it’s now live on PyPI (mastodon-ui==1.0.6).


What it does
Instead of writing this in template.html:


raw HTML:
<div class="card">
{% if user.is_authenticated %}
<h1>Welcome, <span>{{ user.username }}</span></h1>
{% else %}
<h1>Ooops your not regestred!</h1>
{% endif %}
</div>


You write this in your views.py (or a components/ file):



from mui import (

div,

h1,

ElementState,

StateProps,

)


def card(request):
# not a view but more of simplified example
props= StateProps(required=True, prop_is_truthy=['username','is_authenticated'])
input_props ={
'username':request.user.username,
'is_authenticated':request.user.is_authenticated,
}


content = {'welcom_noscript':f'Welcome {ElementState("span", d_state="username",props=props).change_state(input_props,input_props).state_placeholder}'}
return div(
(  ElementState('h1',d_state='welcom_noscript', props=props).change_state(content,input_props).state_placeholder or h1('Ooops your not regestred!')),
Class="card",
)

is_authenticated?:
yes:
<div class="card"><h1>Welcome <span>Olman</span></h1></div>
no:
<div class="card"><h1>Ooops your not regestred!</h1></div>

The Cool Engineering Stuff (Under the Hood)
Building this taught me a ton about system architecture. Here are the main features:


JIT CSS Engine: I didn't want to manage a huge CSS file. MUI scans your Python components at runtime, finds the styles you defined in Python, and generates a minified CSS string on the fly. It only ships the CSS you actually use.


"state management" Architecture: I decoupled the Logic (State) from the Rendering (Elements). This means components can "fail safely"—if data is missing for an element, it just doesn't render, rather than breaking the page.


Django Forms Integration: This was the hardest part. I built a bridge (RequestDataTransformer) that takes a standard Django Form class and renders it using MUI elements automatically (handling CSRF, errors, and widgets).


HTMX Native: Since I wanted a SPA-like feel without JS, I built a fluent API for adding hx-* attributes to any element.


Bootstrap support for common classes: ucan (1) add bs5 classes/attributes to an element or create an element with the classes instead.


Aaand more.


Why I'm sharing
I’m a self-taught developer (shoutout to any ALX peers here!), and this is my first major open-source framework. I’d love for you to roast the code, try it out, or just tell me if I’m crazy for trying to replace templates. Also, the software kinda passed 380 + tests.


If you’re a Django dev who hates context-switching, this might be for you.

GPU-accelerated node-based image compositor with Python automation API (MIT License)

I've released PyImageCUDA Studio - an open-source tool for designing image processing pipelines visually and automating batch generation through Python.

Demo videos:

https://github.com/user-attachments/assets/6a0ab3da-d961-4587-a67c-7d290a008017

https://github.com/user-attachments/assets/f5c6a81d-5741-40e0-ad55-86a171a8aaa4

The problem it solves:

Most image processing libraries (Pillow, OpenCV) require writing code for everything - no visual feedback until you run the noscript. Visual tools (Photoshop, GIMP) have limited or no automation APIs. This creates a gap: design complex effects visually OR automate batch processing, but not both.

PyImageCUDA Studio bridges that gap.

How it works:

1. Design your image pipeline in the node editor (40+ nodes: generators, effects, filters, transforms)
2. See results in real-time via GPU-accelerated preview
3. Save as .pics project file
4. Automate batch generation with simple Python API

Example - generating personalized certificates:

from pyimagecuda_studio import LoadProject, set_node_parameter, run

with LoadProject("certificate.pics"):
    for name in ["Alice", "Bob", "Charlie"]:
        set_node_parameter("Text", "text", f"Certificate for {name}")
        run(f"certs/{name}.png")

Technical highlights:

- Built on PyImageCUDA, my custom CUDA library with native kernels for all image operations
- GPU acceleration: 10-350x faster than CPU alternatives on complex operations
- Real-time preview using CUDA-OpenGL interoperability
- Zero-copy GPU-to-GPU display for instant visual feedback
- No CUDA Toolkit installation required (just NVIDIA drivers)
- Cross-platform: Windows and Linux

Use cases:

- Batch thumbnail generation for content creators
- Personalized graphics at scale (certificates, badges, social media posts)
- Video frame processing (apply effects to entire clips)
- Data augmentation for ML datasets
- Motion graphics and procedural art
- Marketing automation (generate thousands of ad variations)

Tech stack:

- Core: PyImageCUDA (my custom CUDA kernels in C++/CUDA)
- GUI: PySide6
- Preview: PyOpenGL
- I/O: PyVips
- License: MIT

Project status:

Beta release (v0.1.0) - core features stable, gathering feedback for v1.0. Contributions welcome!

Requirements:

- Python 3.10+
- NVIDIA GPU (GTX 900 series or newer)
- Windows 10/11 or Linux

Installation:

pip install pyimagecuda-studio

Run:

1100+ open source cloud projects for learning and resume building


A quick follow up to a previous post about this: https://www.reddit.com/r/Cloud/s/89KNntjVCZ

The open source repository for cloud projects (https://github.com/mzazon/cloud-projects) crossed 1100 (!!) projects recently. AWS, Azure, and GCP all covered. With so many projects, the community contributed suggestions and feedback and being able to search and filter was at the top of the list…

So a couple community members threw together a prototype/beta single page, GitHub pages hosted, no login required, no membership required, all session data stored on your browser page that was just approved and merged into the main branch of the repo: https://cloudprojects.dev

Have a look, give it a star if you like it, open an issue with any suggestions. Hope it is helpful.

Happy holidays to all you cloud professionals and aspiring professionals.

I got sick of ad-bloated utility sites, so I built an open-source alternative (and it looks good).

Hey everyone,

Like many of you, I use random tools daily (JSON formatters, diff checkers, etc.). I got tired of the top search results being ugly, slow, and ridden with ads/trackers.

So I built VoidCraftr (tools.voidcraftr.com).

It’s a collection of common utilities, but designed to actually be pleasant to use.

Let me know if you wanna know about the tech stack.

The Goal: To build the "Swiss Army Knife" of the web that the community actually owns.

It’s fully open source. I’m looking for contributors who want to add their own weird/niche tools to the suite.

Roast it, love it, or fork it. Let me know what you think.

DevConsole - a fun open-source task tracker I originally built for fun

Hi everyone!

I originally started DevConsole as a for-fun side project, without any big plans. I mostly wanted to experiment with a retro terminal-style UI and gamified task management for developers.

Along the way it turned out more interesting and useful than I expected, so I decided to open-source it and share it with anyone who might enjoy or find it helpful.

What it is:

Open-source task management system
Retro / terminal-inspired UI
Designed with developers in mind
A bit playful, a bit cyberpunk

Seemake - CMake project analyzer written in Kotlin

I've started a project called Seamake (which later on I thought hey Seemake makes more sense! but then forgot to change it everywhere).


It's a CMake analyzer, you give it the root project directory and it tries to give you a report on the dependencies and options within that software. Mainly because I have multiple projects that needs package management, building from source and binding Cpp software in Kotlin.


This is a very bad draft but I'm hoping to make this better overtime. You can find it at

What open-source projects do you use to manage scraping or data collection at scale?

I'm experimenting with a few side projects that pull data from APIs and public websites, and once there’s more than one noscript, things get messy fast.

Interested in open-source tools people actually use for scheduling, monitoring, or managing multiple data collection jobs.

Even lightweight setups are fine.. mostly curious what's worked in the real world.
