3 months in Python, I made my first proper 2D game

What My Project Does:
I’ve been messing with Python for about three months, mostly tutorials and dumb exercises. Finally tried making an actual game, and this is what came out.

It’s called Hate-Core. You play as a knight fighting dragons in 2D. There’s sprites, music, keyboard and touch controls, and a high-score system. Basically my attempt at a Dark Souls-ish vibe, but, you know… beginner style. Built it with Pygame, did the movement, attacks, scoring, and slapped in some sprites and backgrounds.

Target Audience:
Honestly? Just me learn-ing Python. Not production-ready, just a toy to practice, see what works, and maybe have some fun.

Comparison:
Way beyond boring number guessing, dice rolls, or quizzes you see from beginners. It’s an actual 2D game, with visuals, music, and some “combat” mechanics. Dark Souls-ish but tiny, broken, and beginner-coded.

I’d love honest feedback, tips, ideas or anything. I know it’s rough as hell.

I built AuthTuna, a modern, async-first security framework for FastAPI with hierarchical permissions

Hey everyone,

I built an async security library for FastAPI called AuthTuna to solve some problems I was facing with existing tools.



# What My Project Does



AuthTuna is an async-first security library for FastAPI. It's not just a set of helpers; it's a complete foundation for authentication, authorization, and session management. Out of the box, it gives you:

* **Fully async** operations built on SQLAlchemy 2.0.
* **Hierarchical RBAC** for complex, nested permissions (e.g., `Organization -> Project -> Resource`), which goes beyond simple roles.
* **Secure, server-side sessions** with built-in hijack detection.
* A familiar developer experience using standard FastAPI `Depends` and Pydantic models.



# Target Audience



This is built for Python developers using FastAPI to create **production-grade applications**. It's specifically useful for projects that need more complex, granular authorization logic, like multi-tenant SaaS platforms, internal dashboards, or any app where users have different levels of access to specific resources. It is not a toy project and is running in our own production environment.



# Comparison



I built this because I needed a specific combination of features that I couldn't find together in other libraries.

* **vs. FastAPI's built-in tools:** The built-in security utilities are great low-level primitives. AuthTuna is a higher-level, "batteries-included" framework. You get pre-built user flows, session management,

Do I really need to learn Django templates if I want to do backend dev?

Hey everyone, I’m currently learning backend development with Django and I’m a bit confused about where templates fit in.

Here’s my thought process so far:
1. Django can return HTML pages using its built-in template system. This is the traditional server-side rendering (SSR) model that a lot of older frameworks also used (PHP, Ruby on Rails, Java JSP, etc.).
2. Nowadays, many apps use client-side rendering (CSR) with React, Vue, etc. In that case, the backend usually just provides a JSON API and the frontend handles rendering.

So my question is: If I want to focus mainly on backend development in Django, do I still need to learn templates?

I made a vs code extension that insults you if you copy & paste AI generated code

-on an important note: this project was just for fun, I'm not against using AI to help your coding sessions-


What my project does:
It's a vs code extension that gives random insults such as "Do you ask GPT what to eat for dinner as well?" to the user if it detects AI generated content. It uses a pretrained transformer-based model for inference (roberta-base-openai-detector), that returns the probability of human and AI writing the given section of text. It was pretty fun to play around with, although not accurate (the model was trained on GPT-2, and not optimized for code, so accuracy is bum), but it was my first time mixing languages together to create something. (In this case typescript and python) It's interesting how extensions like these are set up, I think it's valuable for anyone to do pet projects like these.


Target audience: noone really, just a funny pet project, due to the inaccuracy I wouldn't recommend it for actual usage (it's a bit difficult to create something more accurate, these kind of open-source models were trained on texts, not code)


Comparison: To my knowledge there hasn't been a vs code extension like this before, but there are several much more

Random 404 errors.

I am a beginner, and my Flask app is randomly giving 404 URL not found errors. It was running perfectly, and I restarted the app, but now it is not. Last time it happened, I just closed my editor and shut my pc off, and after some time, it was working again.

I know my routes are correct, and I am using url_for and even my Index page, which i donet pass any values into, is not loading.

Has Anyone else faced these issues before and know how to solve them?

What’s the one Python feature you wish you discovered earlier?

I’ve been coding in Python for a few years, and just recently realized how much time f-strings can save compared to old-style string formatting.

Honestly, I feel like I wasted so many lines of code before discovering this. 😅

Curious — what’s one Python trick, library, or feature that completely changed how you code once you found it?

Why do you like it or why do you hate it.

Everyone has a free space to share their opinions about it!

PS: you don't have to motivate me on why i should or shouldn't use it, i'm already using it for work. This doesn't mean i have a love feeling tho 😂, so i want to read everyone's opinions!

AIWAF Flask: Drop in Security Middleware with AI Anomaly Detection

Just launched AIWAF Flask, a lightweight yet powerful Web Application Firewall for Flask apps. It combines classic protections like IP blocking, rate limiting, honeypot timing, header validation, and UUID tampering checks with an AI powered anomaly detection system. Instead of relying only on static rules, it can learn suspicious patterns from logs and dynamically adapt to new attack vectors.

The setup is dead simple. By default, just pip install aiwaf-flask and wrap your Flask app with AIWAF(app) and it automatically enables all seven protection layers out of the box. You can go further with decorators like aiwaf_exempt or aiwaf_only for fine grained control, and even choose between CSV, database, or in memory storage depending on your environment. For those who want smarter defenses, installing with [ai] enables anomaly detection using NumPy and scikit-learn.

AIWAF Flask also includes a CLI (aiwaf) for managing IP blacklists/whitelists, blocked keywords, training the AI model from logs, and analyzing traffic patterns. It’s designed for developers who want stronger security in Flask without a steep learning curve or heavy dependencies.
