Turn Entire YouTube Playlists to Markdown Formatted and Refined Text Books (in any language)
Give it any YouTube playlist(entire courses for instance) and receive a clean, formatted and structured file with all the details of that playlist.
It's a simple yet effective script using the free Google Gemini API.
I haven't found any free tool available with this scale, so I made one.
This Python application extracts transcripts from YouTube playlists and refines them using the Google Gemini API(which is free). It takes a YouTube playlist URL as input, extracts transcripts for each video, and then uses Gemini to reformat and improve the readability of the combined transcript. The output is saved as a text file.
**What My Project Does**:
* Batch processing of entire playlists
* Refine transcripts using Google Gemini API for improved formatting and readability.
* User-friendly PyQt5 graphical interface.
* Selectable Gemini models.
* Output to markdown file.
**Target Audience**:
Turning large YouTube playlist into one large formatted text file has many advantages for studying and learning, documentation, having a source book of the playlist, etc...
**Comparison**:
I haven't found a similar tool that converts YouTube videos to easily readable document in this scale and be free and accessible.

Time to stop using filter()?
Python's built-in filter() function predates generators, and it has persisted, partly out of habit, partly for legacy reasons, and partly because it can be a bit faster than generators.
Having recently tested the performance of filters vs generators in Python 3.13, I found the speed benefit has reversed. In all of my tests, generators were faster than the equivalent filter call - typically by 5 to 10%.
Is it now time to stop using filter() in new code (Python >= 3.13), or are there still cases where it is clearly the better option?

Starter Django Project (Boilerplate)
Hi all, I am looking for a starter Django project that only has the login, register, reset password, and activate account already set up (send email with activate/reset link). The setting up of the boilerplate is what always prevents me from starting new projects, sadly I am just so lazy.
If anyone knows of a repo that has this please can you point me to it. I will also help maintain it.

Django 5.1 Security Vulnerabilities: What You Need to Know
# Executive Summary (For CEOs & Managers):
* **What’s at risk?** Attackers can exploit these vulnerabilities to disrupt services (denial-of-service) or compromise your database (SQL injection).
* **What should you do?** Instruct your technical team to upgrade Django to the latest secure versions immediately: **5.1.5, 5.0.11, or 4.2.18**, depending on what your systems use.
* **Why it matters:** Even a brief service disruption or successful SQL injection can lead to lost revenue, reputational damage, and compliance issues.
# Technical Breakdown (For Blue Teams & Developers):
# 1. CVE-2024-56374 – IPv6 Validation DoS
**Details:** Lack of a limit on string length when validating IPv6 addresses could allow attackers to overload the system, causing a denial-of-service.
* **Vulnerable Components:** `clean_ipv6_address`, `is_valid_ipv6_address`, and `django.forms.GenericIPAddressField` (Note: `django.db.models.GenericIPAddressField` is not affected).
* **Recommendation:** Upgrade to **5.1.5, 5.0.11, or 4.2.18**. Avoid using these functions in unpatched versions.
# 2. CVE-2024-53908 – SQL Injection in Oracle Databases
**Details:** Direct use of `django.db.models.fields.json.HasKey` lookup with untrusted data can lead to SQL injection attacks on Oracle databases.
* **Attack Vector:** SQL injection when the `HasKey` lookup is used with user-controlled input.
* **Recommendation:** Upgrade to **5.1.4, 5.0.10, or 4.2.17**. Review and sanitize any input passed to `HasKey` lookups.
# 3. CVE-2024-53907 – DoS in strip_tags() and striptags Filter

School Children NFC
Hi, I’m currently working on a school project to create a system for school children using NFC tags. The system is designed to handle attendance tracking and allow students to pay for food in the canteen using NFC. Parents can top up their children’s NFC tag balance through a web app that we’ve developed using Django and Python. I have limited knowledge about NFC, so if anyone has experience with a similar system, I would appreciate any advice or suggestions.

Getting told “PL/SQL is a better option compare to Python” on Report Automation
Background: Recently I’m working on a report automation task using Python Pandas library, but - I was told by the TI team (Tech infra) that currently they are having issues with the Pandas library on the servers, so I’m asked to find alternatives to revise my finished program…
The problem is while I’m looking for alternatives, I’m getting a lot of options or ideas from not just my own team, but other teams.
And one of the Senior employees on my team asked me what my Python program is doing, after I explained my program logic, he basically told me “You shouldn’t use Python for this task in the first place. Should just use PL SQL” Because:
1. PL SQL is being used by my team for a long time, most of people are more familiar with it.
2. Using PL SQL avoids the Python Libraries issue
3. It’s approved by the company so no need to worry about “getting approvals”
Maybe this option could work and he is trying to help, but I’m not convinced by his explanations on why PL SQL is a better option specifically in the context of the report automation task which requires:
1. Iterating through each rows of data, uses

R LLMs as Few-Shot Data Annotators for Multilingual Text Detoxification
This paper introduces a method for using LLMs as few-shot learners to generate high-quality parallel datasets for text detoxification. The key innovation is using modern LLMs to create paired toxic/non-toxic text examples that maintain semantic meaning while reducing toxicity.
Main technical points:
- Uses few-shot prompting with carefully curated example pairs
- Implements multi-stage filtering to ensure quality
- Validates semantic preservation using automated metrics
- Achieves better toxicity reduction while maintaining meaning compared to existing methods
- Creates larger, higher-quality parallel datasets than previous approaches
Results:
- Outperforms existing detoxification models on standard benchmarks
- Shows strong cross-domain generalization
- Demonstrates effectiveness with just 3-5 examples
- Maintains semantic similarity scores >0.85
- Reduces toxicity scores by >60% on test sets
I think this could be particularly valuable for content moderation systems that need to preserve meaning while removing harmful content. The ability to generate high-quality parallel data could help train better downstream detoxification models.
I think the few-shot approach is especially promising because it reduces the need for large annotated datasets, which are expensive and time-consuming to create manually.
TLDR: Modern LLMs can generate high-quality parallel toxic/non-toxic text pairs using few-shot learning, enabling better training data for detoxification systems while maintaining semantic meaning.
Full summary is here. Paper here.

Pykomodo: A python chunker for LLMs
Hola! I recently built **Komodo**, a Python-based utility that splits large codebases into smaller, LLM-friendly chunks. It supports multi-threaded file reading, powerful ignore/unignore patterns, and optional “enhanced” features(e.g. metadata extraction and redundancy removal). Each chunk can include functions/classes/imports so that *any* individual chunk is self-contained—helpful for AI/LLM tasks.
If you’re dealing with a huge repo and need to slice it up for context windows or search, Komodo might save you a lot of hassle or at least I hope it will. I'd love to hear any feedback/criticisms/suggestions! Please drop some ideas and if you like it, do drop me a star on github too.

* Anyone who's needs to chunk their stuff

What I learned about Django security from my hidden analytics module
I built a hidden statistics module in my Django portfolio and discovered something interesting about security
I added a secret stats endpoint to my Django site that tracks all attempts to access my site. After analyzing 2.2k unique visitors, the data tells an interesting story.
Legitimate traffic is exactly what you'd expect: homepage (2.6k visits), portfolio (911), blog (661). But here's where it gets fun - my stats module caught hundreds of automated attacks trying everything from .env file access (64 attempts) to WordPress admin panels.
The best part? I didn't build any special security - Django's default configurations handled everything. The stats module just silently recorded all these failed attempts while serving my actual visitors without a hitch.
My favorite discovery was seeing the persistence of some bots - one tried +50 different variations of WordPress manifest files. On a Django site. I actually found myself admiring their determination.
TL;DR: Built a secret stats module in Django, watched it record thousands of failed hack attempts while Django's security didn't break a sweat.

A polyphonic MIDI synth in less than 100 lines of code
# 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/supriyapython.
The code for all demos can be found in this GitHub [repo](https://github.com/dayunbao/supriyademos).
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 this demo, I show how to handle MIDI messages to play a polyphonic synthesizer using Supriya. It took a little less than 100 lines of code, which is pretty amazing.

Python pdf bytes stream to Postman
I acknowledge that the question might not be fully flask related.
Essentially I have a flask endpoint that takes a few arguments and stores a PDF File + an analytical object tied to it in MongoDB. One of the arguments passed to the endpoint is the pdf byte stream of the PDF itself.
I am trying now to test the endpoint via postman but I struggle to define to include the pdf byte stream as I can't seem to be able to copy the entire value of it from python. Has anyone else ever encountered a similar issue, i.e., manually defining a pdf byte stream as a parameter argument in postman?

I am creating a site that will need something similar to mods and subreddit. Should I create a mod called a super mod that can edit everything?
Hey I am sorry if this a dumb question and I am inexperienced.
Also a forum might be a better analogy.
I am building a simple admin features in flask for my app. But I have a question when designing the database. The analogy in my site is kind of like reddit mods and subreddit. I want to make is so only mods can create a new subreddit. Seems easy enough. Now my question, should I create a super mod that can edit everything? One of the negative is that if a super mod was hacked the entire site could go down. Or am I worrying about nothing? Also should I just make it so the first user is automatically a super mod and just add super mods and mods?
I am using flask sqlalchemy if that makes a difference also.

My talk has been accepted for DjangoCon EU 2025!
“What if I fail?”
That thought used to haunt me every time I took a step outside my comfort zone. Applying for my first open-source contribution, organizing Django meetups, even sharing my thoughts publicly—self-doubt was always lurking.
But today, I have proof that pushing past fear leads to something bigger. My talk on Zango framework has been accepted for DjangoCon EU 2025! 🎉
This isn’t just about a conference talk. It’s about the journey—the long nights, the imposter syndrome, the relentless belief that if you keep showing up, opportunities will follow.
From casually exploring Django to building a thriving community in India, from contributing in silence to speaking on an international stage—it’s been a wild ride. And if there’s one thing I’ve learned, it’s this:
“Do it. Even if you think you’re not “ready” yet”
Because the best things happen when you stop waiting for permission.
