DRF Deployment
Hi there, I am fairly new to Django and DRF, I have never deployed a django project but have built small development APIs to learn.
I'm trying to deploy a project with gunicorn and nginx (if there is a better alternative, please let me know)
#PROBLEM
I keep running into an issue where my django admin panel hangs frequently, or takes up to 4s to load the page. Check Chrome tools it's usually jsi18n which takes the most time. My apis calls also have a tendency to hang and ends up timing out. I'm using AWD RDS postgres db.
#TRIED
- Upgrading DB
- Checking my SQL queries (at most 500ms)
- Increasing gunicorn workers
- Changed nginx configuration
#INFO
- I have 2 custom models, an altered base user model and a password otp model
- I'm using simple_jwt
- The hanging or long loading can happen on any call or any django admin page (except login page)
If there is any more information, code examples, please let me know.
I'm really struggling to find modern Deployment techniques for DRF, atm my setup is Docker, gunicorn and nginx. If anyone has any up to date resources for better deployment, I would be incredibly grateful.

Should I Prioritize Learning Programming (Like Python) for AI and Machine Learning After 12th Grade?
I just gave my 12th-grade exams a few weeks ago, and I feel like I might just barely pass. Should I learn a programming language like Python or not? Because I feel like I’m going to waste the next 2-3 months, and once I start doing something, I can only dedicate about 4 hours a day to it. I also want to learn a lot about AI and Machine Learning, as I think I’m interested in this field. For this, I know I need to learn programming languages. So, should I prioritize coding or not?

Proposal: Native Design by Contract in Python via class invariants — thoughts?
Hey folks,
I've just posted a proposal on discuss.python.org to bring Design by Contract (DbC) into Python by allowing classes to define an __invariant__() method.
The idea: Python would automatically call __invariant__() before and after public method calls—no decorators or metaclasses required. This makes it easier to write self-verifying code, especially in stateful systems.
Languages like Eiffel, D, and Ada support this natively. I believe it could fit Python’s philosophy, especially if it’s opt-in and runs in debug mode.
I attempted a C extension, but hit a brick wall —so I decided to bring the idea directly to the community.
Would love your feedback:

Polars vs Pandas
I have used Pandas a little in the past, and have never used Polars. Essentially, I will have to learn either of them more or less from scratch (since I don't remember anything of Pandas). Assume that I don't care for speed, or do not have very large datasets (at most 1-2gb of data). Which one would you recommend I learn, from the perspective of ease and joy of use, and the commonly done tasks with data?

Django patterns for tables in components
I'm building a dashboard of sorts, which will have multiple tables in blocks - each with its own pagination, filtering and sorting
I really like Iommi (for tables) and django-cotton (for components), and considering unpoly or HTMX - is there a way to make them work together?
I was able to get Iommi working fine, but I can see the query parameters are passed to the url, which breaks things - are there any examples or best practices around this?

Looking for Feedback: HTMX + Django Package
I posted about this package a while ago, but at that point, it was still early in development, and the documentation was lacking. Since then, it has matured a lot, and the documentation has been completely restructured and improved. Additionally, I’ve created a demo site so you can see the package in action with a basic list page featuring CRUD operations (link below).
The core idea of the package (explained in more detail in the docs) is to provide quasi-Django CBV-style views, called hx-requests, which HTMX requests are routed to. This approach separates HTMX-specific logic from your main views by providing dedicated hx-requests to handle them, but at the same time these hx-requests have access to the view’s context, eliminating the need for logic duplication.
There are also other useful features, such as:
* Returning template blocks easily from an hx-request
* Built-in support for Django messages, now with async capabilities
* Integrated modal handling
It’s difficult to summarize everything here, so I’d love for you to check out the demo and documentation and share your feedback!

Playa PDF: A strong pdfminer successor
Hi there fellas,
I wanna intro you to a great library - not one of mine, but one which I feel deserves some love and stars.
The library in questions is PLAYA which stands for "Parallel and/or LAzY Analyzer for PDF".
What is this?
This library is similar in scope to pdfminer and its fork pdfminer.six - long-established libraries for manipulating and extracting data from PDF files.
It is partially based on pdfminer.six and includes code from it - but it substantially improves on it in multiple ways.
1. It handles a broader range of PDFs and PDF issues, being very close to the (horrible) specification. For example, the author of the library (dhaines) has recently added an enormous test suite from PDF.js (one of the more ancient libraries in this space), which includes a whole gamut of weird PDFs it can handle.
2. It's much faster - well, as far as Python goes, but it is faster than the other Python libs by a factor of at least two, if not three, and not only when parallelizing.
3. complete metadata extraction - this part is what got me into this since I am integrating this with Kreuzberg now (a library of mine, which you

Something's wrong!
I'm trying to learn django with w3schools tutorials. I learned python there and it was fine. I learned numpy and pandas and they were easy and readable and comprehensible. But now in the django tutorial I find myself completely lost!
Look I don't even know where the problem is. is it me? is it the tutorial? the django itself?
Cause I haven't worked web before at all. I didn't even knew how to find directory in cmd but I'm researcher at heart. I dig deep and figure it out. But I find myself, with django, in a state of despair. I'm up till models tutorial and still copy-pasting stuff and I don't know why. There are lots of lines to copy which none I'm familiar with and since I don't understand them, repeating them and writing them doesn't help either. Tutorial doesn't explain these to me and I honestly for the first time feel overwhelmed.
Should I have a background in web dev then I learn django? Am I missing something?

Using Polars as a Vector Store - Can a Dataframe library compete?
Hi! I wanted to share a project I've been working on that explores whether Polars \- the lightning-fast DataFrame library - can function as a vector store for similarity search and metadata filtering.
What My Project Does
The project was inspired by this blog post. The idea is simple: store vector embeddings in a Parquet file, load them with Polars and perform similarity search operations directly on the DataFrame.
I implemented 3 different approaches:
1. NumPy-based approach: Extract embeddings as NumPy arrays and compute similarity with NumPy functions.
2. Polars TopK: Compute similarity directly in Polars using the top_k function.
3. Polars ArgPartition: Similar to the previous one, but sorting elements leveraging the arg\_partition plugin (which I implemented for the occasion).
I benchmarked these methods against ChromaDB (a real vector database) to see how they compare.
Target Audience
This project is a proof of concept to explore the feasibility of using Polars as a vector database. At its current stage, it has limited real-world use cases beyond simple examples or educational purposes. However, I believe anyone interested in the topic can gain valuable insights from it.
Comparison
You can find a more detailed analysis on the README.md of the project, but here’s the summary:

Column data getting mixed up in SQLAlchemy database for rows at random
So here is the deal. I have a list of dictionaries which I am looping through, adding each of the keys to a database in each iteration of a loop. After the entire list has been added and committed to the database, I look at the database, and randomly (or it seems random at least), there are rows that are duplicated but when several of the column data shifted to the wrong column. Most of the time, it seems like a duplicate row where this happens (one row is fine, the other is screwy), but I have seen at least one row where there isn't a duplicate but its columns are mixed up.
If all rows are like this, then I would gather that the issue is somewhere in my code, the way that I am adding data to the columns of my database in the flask app logic, but since most rows are okay (maybe 80%), I'm not too sure what is going on is in the logic but rather somewhere else.
See the attached picture for an example of the database record which is faulty (row 17, which seems to be a faulty copy of row 18) and below for

-That would find an high quality image on the internet
-And all I simply have to do is to give it the mp3 and it does the rest and even upload to the channel. It would be nice if it could go through the channel and check which the thumbnails used in the videos to get a feel of what kind if image to use.

How I Helped a Beginner Learn Power BI, Excel & Python for Data Analysis
A few months ago, I started helping people learn data analysis, even if they had zero experience. One of my students, who had never used Power BI or Python before, went from complete beginner to confidently analyzing real-world datasets in just three weeks.
I’ve noticed that many beginners struggle with:
✅ Choosing the right tool (Excel? Power BI? Python?)
✅ Cleaning and visualizing data effectively
✅ Building projects that actually get attention
So, I put together simple, beginner-friendly tutorials that help people master Power BI, Advanced Excel, Tableau, and Python without feeling overwhelmed.
If you’re curious about data analysis and want to learn in a practical, no-jargon way, I’m happy to share some free beginner tips to get you started.

A low-pass filter with an LFO
# Background
I am posting a series of Python scripts that demonstrate using Supriya, a Python API for SuperCollider, in a dedicated subreddit. Supriya makes it possible to create synthesizers, sequencers, drum machines, and music, of course, using Python.
All demos are posted here: r/supriya\_python.
The code for all demos can be found in this GitHub repo.
These demos assume knowledge of the Python programming language. They do not teach how to program in Python. Therefore, an intermediate level of experience with Python is required.
# The demo
In the latest demo, I show how to create a resonant low-pass filter and modulate the filter's cutoff frequency with a low frequency oscillator.

pnorm: A Simple, Explicit Way to Interact with Postgres
GitHub: https://github.com/alrudolph/pnorm
# What My Project Does
I built a small library for working with Postgres in Python.
I don’t really like using ORMs and prefer writing raw SQL, but I find Psycopg a bit clunky by itself, especially when dealing with query results. So, this wraps Psycopg to make things a little nicer by marshalling data into Pydantic models.
I’m also adding optional OpenTelemetry support to automatically track queries, with a bit of extra metadata if you want it. example
I've been using this library personally for over a year and wanted to share it in case others find it useful. I know there are a lot of similar libraries out there, but most either lean towards being ORMs or don’t provide much typing support, and I think my solution fills in the gap.
# Target Audience
Anyone making Postgres queries in Python. This library is designed to make Psycopg easier to use while staying out of your way for anything else, making it applicable to a wide range of workloads.
I personally use it in my FastAPI projects here’s an example (same as above).
Right now, the library only supports Postgres.

Interactive Python Learning Series: From Numbers to Exceptions
Hey Python folks,
I wanted to share a project I've been working on, creating interactive Python tutorials — series of Python fundamentals notebooks in our marimo-learn repository.
What This Project Does: We've built tutorials covering the Python journey from basics to more complex topics. The notebooks are reactive — change code in one place and see updates ripple through in real-time, which makes learning way more intuitive. The content covers Python fundamentals (data types, strings, collections) and builds up to functions, modules, and exception handling. What makes these different is that they're fully interactive and run natively in your browser (thanks to WASM & Pyodide).
Target Audience: Python learners and teachers who prefer hands-on experimentation over passive reading; devs who want to explore Python concepts through an interactive medium rather than static documentation.
Comparison to Alternatives: Unlike static tutorials or videos, these notebooks combine explanation, code, and output in a reactive environment. When you modify code in one cell, all dependent cells automatically update, showing how concepts interconnect.
Source Code: All notebooks are available at /python folder, organized in an appropriate progression (in terms of topics).
We're also looking for Python enthusiasts to contribute additional specialized tutorials. If you're interested, check out our GitHub repository for
