What is the purpose or a use-case of a Django admin?
I always ever worked with FastAPI, Flask and ExpressJS for creating APIs for web projects, and now I'm trying out Django.
I followed a tutorial to try setting up and re-doing API's I've built with the other frameworks, and I found myself with a dozen tables related to Django, popping up in my database.
I went to the /admin route and saw that I could login.
What is the purpose of having this kind of user management for accessing the database? I never had to use anything like that with the other frameworks.
Is that suited for some kind of work environment where you want to give employees certain rights, like some can't add new tables and others can? Is that the scope of this admin feature?
If so, I guess I can skip it for my personal projects?

Any tips for courses with a full application that aren't on video?
I recently discovered William Vincent's book which is a step by step application, starting with Docker, I'm looking for things like that because it's a way to learn DevOps as well. However, most of them are Udemy courses, and video is more complex!
Note: The only problem with the book is that it's from 2019, but I'll adapt to the time.

simple project suggestion
i don't know if this is the place to ask this but can you suggest a github repo of a simple (not necessarily) django project that inside it users can enter their information inside a form and then the website has a section that displays all these users somewhere, anything remotely close to this is good enough i'll change it up a little bit, its a project for my teacher but i don't have a lot of time to do it all myself, just need a simple local project, Thank you in advance

D Efficient way to store large datasets
I’m collecting trajectories for imitation learning (RL) and each trajectory is about 1500 time steps long, consists of 4 image streams of about 600x600 pixels.
Obviously, the dataset size grows extremely quickly with the number of trajectories.
What are some good libraries for efficiently (in terms of disk space) storing such data? I tried h5py with level 9 gzip compression but the files are still way too large. Is there a better alternative?
Saving and loading times do not really matter.
Most resources online are aimed at efficiently loading large datasets or handling them in memory which is not relevant for my question.
I already use uint8 as datatype for the rgb streams.

Introducing WSCE: A Custom Shell Environment Built with Python
Over the past few weeks, I've been working on a custom shell environment called **WSCE**. Built entirely in Python, it mimics the functionality of an operating system and comes packed with features like a fake boot sequence, a text editor, and more. It's designed to provide a unique experience that blends the line between an OS and a shell environment.
# What My Project Does
WSCE is a simulated operating system environment built as a Python-based shell. It offers a range of features such as:
* **FakeBoot:** Emulates the boot process of an actual operating system.
* **Aurora Text Editor:** A simple text editor to mimic basic productivity tools.
* **CommandSearch:** A script that searches a folder for python files to make into custom commands
# Target Audience
This project is primarily a passion project and is not intended for production use. It is targeted at hobbyists, Python developers, and those interested in exploring custom shell environments or unique OS simulations. It's perfect for those who enjoy tinkering with code and experimenting with unconventional software projects.
# Comparison to Existing Alternatives
WSCE stands out because it's not like any other shell environment or operating system out there. Unlike traditional shells or full OS environments, this project focuses on simulating

[P] This week, I implemented the paper, "Pay Attention to MLPs", in Tinygrad! :D
To experiment with more interesting model architectures, I implemented gMLP in Tinygrad!
If anyone wants to give some feedback, it will be welcomed.

PEP695 Migration Tool
Now that PEP 695 is a little over 2 years old and it has been almost a year since it was officially introduced in python 3.12, the new type parameter syntax will slowly become the standard way of defining TypeVars, ParamSpecs and TypeVarTuples as well as creating Type aliases with the type keyword. After I spent some time using python the last couple of weeks, I realized that adapting "old" projects of mine to the new syntax really takes more time than I'm willing to invest, especially as some have a pretty large codebase.
# What My Project Does
This is why the past few days I spent time building pep695, a tool that automatically rewrites code to conform to PEP 695 syntax for you.
Install pep695 using pip:pip install pep695
Format code using pep695 format <path1> <path2> <pathN> ... [-p | --parallel] or just check for errors using pep695 check <path1> <path2> <pathN>. I just published this project today which is why I'm still looking for people to test this project on their own codebase, doesn't matter if it's small or large, any feedback is appreciated!
More info, including examples of code that pep695 can rewrite for you on the github repo:

nb2dash: Convert Jupyter notebooks to interactive dashboards with WASM
Hey r/ipython! Today, I'm lauching nb2dash, a tool to convert Jupyter notebooks into dashboards, and I'd love to get your feedback.
https://nb2dash.ploomberapp.io
You can see a sample dashboard here: https://nb2dash.ploomberapp.io/notebook/bb8086c0
https://reddit.com/link/1f9rajw/video/hr40j3dht0nd1/player
# What it does
Upload your Jupyter notebook (.ipynb file)
Get back a link to an interactive dashboard version of your notebook
# Target Audience
Data practitioners who want to easily share an interactive analysis, machine learning model or any other interactive app.
# Key features
Free to use: No sign-up required
Easy: Just drag and drop your notebook file
Quick: Processing usually takes 1-2 minutes
Shareable: Get a link you can send to anyone
# Tech stack
Flask for the web app (receive uploads and process notebook)
NGINX for rendering processed notebooks
Voici for converting notebooks into standalone WASM pages
Redis and rq for task queueing
# Comparison
When people want to share a notebook, they often convert it into HTML or PDF. However, this is hinders interactivity. Alternatively, you might use Voila to deploy it as a web app but that requires paying to a hosting provider. Voici uses WASM, meaning your notebook is a static site and all compute happens locally, reducing cost by a huge margin. Note that WASM and Voici are still early technologies

I've been tracking Python, Django, NumPy and several other frameworks in job listings this year
Hi all, I built a website to track programing languages/skills/frameworks in jobs.
Perhaps unsurprsingly Python is by far the biggest category in software engineering:
I'm tracking many other Python frameworks and libraries as well:
[Django](https://job.zip/trend/django)
Scikit-learn
[NumPy](https://job.zip/trend/numpy)
Flask
[FastAPI](https://job.zip/trend/fastapi)
Keras
[MicroPython](https://job.zip/trend/micropython)
Ruff
I hope this is of some use of you, if there's another framework you'd like me track, please let me know!
Also there's a Python component as well, I use Python to identify trends in my dataset. Every month I load up 10 million new jobs and compare them with the months before to identify new types of jobs to add to the site.

Yet another 12 factor configuration helper : python-direnv
Hi Python! I've developed another app to manage environment variables.
# What My Project Does
This allows you to `load_direnv()` your environment variables like `load_dotenv()`, once you allow them through `direnv`, but unlocks the full power of the bash shell instead of being limited to basic key-value pairs. Contributions welcome (the package is not yet on Pypi.org, working on it) !
# Target Audience
If you are developing using the 12 factor app principles and are a user or direnv, Nix, or Guix you might want to check out this package I just wrote : https://github.com/nicolas-graves/python-direnv
# Comparison
This package is actually quite different to other similar projects. It doesn't use a parser but loads environment variables based on shell environment changes. This allows for instance full environment configuration using Nix or Guix for instance, thus providing a way to load a complete environment from a simple `__file__` variable, in any Python project. I have another project on the way that needed this for real-life application ;)

Alternatives to Jinja for Flask-Based Desktop App Using PyInstaller and WebView
I'm developing a desktop application using the following tech stack:
Frontend: HTML, CSS, JavaScript, Jinja2 (current template engine)
Backend: Flask
Packaging: PyInstaller to create a `.exe`
UI: WebView for Windows
I am currently using Jinja2 for templating, but I want to explore other template engines that might provide better performance or additional features. My main requirements are:
1. Compatibility with Flask: Should integrate easily without much configuration.
2. Support for Desktop Apps: Must work well with PyInstaller when packaging the app.
3. Efficient Rendering: Performance is key, as the app is intended for desktop use.
Are there any good alternatives to Jinja2 that would fit well within this stack? Any advice on integration or potential challenges would be appreciated!
Thank you!

Understanding apps, forms, and the structure of a project/app
Hello everyone,
I am basically a beginner trying to use Django in order to build an app for a business I work for. I have experience with programming, but I never built any app (or web based one).
After going through the Tutorial of Django, I jumped and started programming.
I decided to use various apps instead of having one app because I couldn't focus on the tasks needed and it was a cluster of code.
I began with 2 applications: forms - allows essentially forms management/everything to do with forms: processing, validation etc, and users app - user management, authentication, user settings and so on.
I started to create a login form and login form view. the login form has its own clean methods, and the login form view allows me to forward the form and reder it in HTML loginForm/. I decided to render only the form itself, but I will have a proper "login/" page will the loginForm/ will be imported to. As I said earlier, it is because the forms app is only responsible for the forms, and the rest of the page will be done by something else.
after I wrote all of what I mentioned, I realized that Django has
