Question about storing audio files

I am creating a web application where you can put music files inside that are added to a list where you can start, delete and eventually download in the future all your files that you have put. Now, what I was thinking of doing was using a database that keeps the path where each user's files are (divided into folders and subfolders; example: songs/Amanda56/song.mp3). I was thinking of creating these in urls that are added dynamically over time (example: when a user registers with the nickname Giorgio192, a url called: https:/www.mysite.com/storage/songs/Giorgio192/ will be created. The songs url already exists, the one that will be added is Giorgio192 (his username therefore). When Giorgio192 adds a new song to his list, this song will be stored in songs/Giorgio192/song.mp3 while the url that is used to extract the songs from there will be saved in my database. Is this method strange? Would it slow down my site a lot over time? If so, how? Is there a way to do what I want?

D From Unemployment to Lisp: Running GPT-2 on a Teen's Deep Learning Compiler

A couple months ago I found myself unemployed, uncertain about what to do next. I wanted to learn more about deep learning, but from a systems prespective. Coming from Andrew's Ng course on supervised learning, I was eager to learn more about how deep learning frameworks (or deep learning compilers) like Pytorch or Tinygrad.

I started to poke around Tinygrad, learning from the tutorials I found online, and I found it fascinating because it was an actual compiler, it took conventional python code and translated them into an Abstract Syntax Tree that was parsed into UOps and ScheduleItems, to finally have a codegen layer. While the design was interesting, the code was hard to read.

That's when I stumbled across something completly unexpected, A deep learning compiler built on Common Lisp, maintained by a Japanese 18-year-old during his gap year. And currently we have acomplished something great, it can run gpt2!

For now, it just generates C-kernels, but in the future we would like to support cuda codegen as well as many other features, and serve as a learning tool for anyone who would like to get to work on deep learning compilers in Common Lisp.

This is an open source project and anyone

D Why are the Stella embedding models so much smaller than other models of similar quality?

On the MTEB Leaderboard, stella_en_v5 is currently ranked 3rd overall, while using one fifth the memory of all non-Stella models in the top 10.

stella_en_400M_v5 is ranked 10th, while using 15-20 times less memory than the models ranked near it. This appears to be relatively consistent across several subtasks of the benchmark (for English).

What is the secret sauce here? Alternatively, what is the catch? There is no paper yet. Anyone know details?

Did an open source tool for code exploration

# Denoscription

Treeline is a code analysis and visualization tool designed to help developers understand the quality and structure of their Python codebases. It does some complexity metrics, detects code smells, and generates an interactive HTML-based visualization for relatively easy exploration. I hope it will give developers some insights into architectural dependencies, complexity hotspots, and maintainability issues.

# Links

* [https://github.com/duriantaco/treeline](https://github.com/duriantaco/treeline)
* [https://pypi.org/project/treeline/](https://pypi.org/project/treeline/)

# What My Project Does

* **Dependency Analysis**: Identifies which modules import others, which classes belong to which modules, and which functions call which, creating a complete dependency graph.
* **Metrics Computation**: Calculates cyclomatic complexity, cognitive complexity, maintainability index, function length, and code smell occurrences.
* **Visualization**: Renders an interactive HTML report using D3.js, where each node represents a module, class, or function. You can hover over nodes to see detailed metrics, search for specific elements.
* **Quality Reporting**: Produces Markdown and HTML reports summarizing complexity hotspots.

# Target Audience

* Anyone using Python

# Extra Details

Started of as a simple ASCII tree generator. Promised to add more stuff so here i am.

# Conclusion

Hopefully you guys will find it useful. If you think it's a stupid idea or ways to improve, do let me know too. I'm open to criticisms and constructive feedback. If you find any bugs

Django Web Application Hosted on LAN

Is it possible to set up a centralized application server that hosts a Django web app and a local database, allowing clients on separate computers to access the app for CRUD operations (e.g., managing mail/blacklists) while storing updates locally? The server would also communicate with a ROS2 system on another computer (running AI models and managing daily logs) and optionally sync data to the cloud. Are there any potential challenges or considerations with this architecture?

Nodriver - The next step in web scraping

Hey guys! Scraping is something we've all needed at some point, whether for personal or professional reasons. But nowadays I feel like I get blocked immediately if I go to any website and tbh I don't want to setup complex patches and go through all that stuff for like a tiny thing. Nodriver solved this problem for me.

Here's an article I wrote about getting started with nodriver and how it faces up with the competition - https://www.hyperbrowser.ai/blog/nodriver_:_The_next_step_in_web_automation

Proof of PCAP Certification?

For those of you who have taken (and passed) the PCAP, did you receive anything other than the paper printout after the exam? (I know the PCAP isn't particularly useful, but my company offered me a 3% raise if I passed it so...) I'm just wondering if I should expect an email with some official looking certification or if I should just show the exam printout to my company.

Introducing My New Favicon Extraction Tool

## What My Project Does

I've created a tool that extracts favicons from any website. It works by parsing HTML pages, checking fallback routes for icons, and even supports inline base64-encoded images. The tool can also verify availability, guess missing icon sizes, and download the favicons for further processing. It aims to streamline favicon retrieval for web scraping, data analysis or just curious exploration.

## Links

- Source code: https://github.com/AlexMili/extractfavicon/
- Documentation: https://alexmili.github.io/extractfavicon/


## Target Audience

The project is designed for developers and data enthusiasts who work with web metadata. Whether you’re building a crawler, enhancing a web directory, or simply analyzing website branding. My intention is to maintain and improve it, making it stable and ready for production use cases.


## Comparison

While there are other favicon extraction libraries out there, many of them have become unmaintained or lack features like asynchronous support, thorough availability checks, and automatic size guessing. My project is actively maintained, built with modern Python standards, and provides a more robust, flexible solution than many existing alternatives.

How to test Flask with dummy DB

Hi, I have been making a Flask CRUD API, I am using pytest to test the models and everything that can be done without having to initialize the Flask App. However, now I really need to start testing the endpoints. I have checked https://flask.palletsprojects.com/en/stable/testing/ and I am getting a general idea on how to do so, however, I am still a bit lost on how to initialize the database and populate it during the testing. Would love any tips :)

Why is this retrieve method incrementing the viewcount by 2 instead of 1 ? .

class ArticleViewSet(ArticleViewSetMixin, viewsets.ReadOnlyModelViewSet):
    filtersetclass = ArticleFilter
    permissionclasses = (AllowAny,)
    queryset = Article.objects.filter(publisheddatelte=datetime.now(tz=IST))
    serializerclass = ArticleSerializer

    def retrieve(self, *args, **kwargs):
        instance = self.getobject()
        Article.objects.filter(pk=instance.pk).update(viewcount=F("viewcount") + 1)
        instance.refreshfromdb()
        serializer = self.getserializer(instance)
        return Response(serializer.data)


Each time i send a postman request, its incrementing the view\count by 2 instead of 1 ? .
why is that ? .
I also don't have any separate signals or anything, this is the only method I have overridden.

Help needed: Flask not loading images in one template

https://preview.redd.it/isayd97rhd6e1.png?width=900&format=png&auto=webp&s=defc230877ba3f07585cb25cf2693309808682dd

Hello,


I'm new to Flask and having trouble with images in one of my templates (`login.html`). Images load fine when `dashboard.html` using `{{ url_for('static', filename='images/logo.jpg') }}`, but the same code doesn't work in `login.html`. Similarly, the CSS file (`/static/css/styles.css`) also doesn't load for `login.html`.

I've checked the file structure and paths, cleared my browser cache, and tried hardcoding the image paths (`/static/images/logo.jpg`), but no luck. Whenever I load the HTML page separately with the hardcoded path, it works fine.

What could be causing this inconsistency? I would appreciate any help!



**Login.html:**

<header>
<img src="/static/images/logo.jpg" alt="logo">
<!-- <img src ="{{ url_for('static', filename='/images/logo.jpg') }}"> -->
</header>
<footer>
<!-- Bottom-center motto -->
<img src="/static/images/motto.jpg" alt="motto">
</footer>


**Dashboard.html:**

<header>
<!-- <img src="{{ url_for('static', filename='images/logo.jpg') }}" alt="Logo">-->
<img src="/static/images/logo.jpg" alt="logo">
<button class="logout-btn" onclick="
window
.location.href='{{ url_for('logout') }}'">Logout</button>

How to upload files to server using django rest framework (i'm using flutter for the front end)

I'm building a user application which allows user to upload designs for saree's (basically the app is going to be used in textile industries in precise) here i stuck with the file uploading part like how to upload files which are around 2-30mb to the server using DRF.
for context the app is going to communicate with the machine using mqtt protocol so once the design is uploaded to the server it will then be used by the machines.

Please let me know if you have any suggestions on this matter as it would be very helpful.
