How does Python 3.13 perform vs 3.11 in single-threaded mode?

When Python 3.12 was released, I had held back from migrating my Python 3.11 applications as there were some mixed opinions back then about Python 3.12's performance vs 3.11. Then, 3.13 was released, and I decided to give it some time to mature before evaluating it.

Now, we're in Python 3.13.3 and the last bugfix release of 3.11 is out. When I Google'd, I only found performance studies on Python 3.13 in its experimental free-threaded mode, which is definitely slower than 3.11. However, I found nothing about 3.13 in regular GIL mode.

What are you guys' thoughts on this? Performance-wise, how is Python 3.13 compared to Python 3.11 when both are in GIL-enabled, single-threaded mode? Does the experimental JIT compiler in 3.13 help in this regard?

I've created a simple social media scheduling app with just Django and Alpinejs

Django is such an underrated web framework.

Not sure about you, but my feed is full of javascript frameworks like Nextjs (which introduces breaking changes every 3 months) and is no where near the features Django provides.

But, that's probably because there are more javascript devs than python devs?

And since Django is an old framework with great documentation and questions on the internet on various topics - it works pretty well with LLMs and it helps with speeding up development.

The app is open-source you can check it out here:

https://github.com/ClimenteA/social-media-posts-scheduler


Works as a boilerplate too if you remove the specific code for the app.

Favorite Admin UI configs

What are some of your favorite admin UI configurations?

Django examples, libraries, packages all welcome!

I’m super basic, just adding backend functionality stuff, organizing custom app labels with a simple 50 line custom_admin.py file etc, but I’m thinking to give the ui a makeover, might even do something dynamic..?

I see some neat lil packages and stuff on a few YT vids but -

Whatchy’all doin’?

Debugging Python f-string errors

Today, I encountered a fun bug where f"{x}" threw a TypeError, but str(x) worked. Join me on my journey unravelling what f-strings do and uncovering the mystery of why an object might not be what it seems.

Server and my flask app keeps crashing on VPS.

Hello, I am running a VPS with my flask [app.py](http://app.py) which I can access with ssh. My application is running well for one or two days and then it suddenly stops. I tried to resolve it for many rounds with ChatGPT or LeChat but it won't stop happening. My logs are not helping so much and all the logs in error.txt and output.log also appear when the server is still running fine.

**Now I wanted to ask if I am doing something fundamentally wrong? What am I missing..**

I tried:

* fail2ban. Are bots crashing it?
* checking memory which seemed to be fine
* running a cronjob (monitor\_flask.sh) to at least restart it. But that does not seem to work either.

**Last logs from my error.txt**:

>multiple of these lines >>> 2025-04-26 21:20:06,126 - app - ERROR - Unhandled Exception: 403 Forbidden: You don't have the permission to access the requested resource. It is either read-protected or not readable by the server.

**Last logs from my output.log**

I built ErrorTrace Pro — Make Python errors visual, easier to understand, and log to the cloud

Hi everyone 👋,

I always felt Python error tracebacks were... ugly and sometimes confusing, especially on bigger projects. So I created ErrorTrace Pro — a library to:

Make tracebacks beautiful and visual
Suggest solutions for common errors
Send errors automatically to the cloud for analysis
Help debug faster and smarter

# Why I built it:

I got tired of reading endless walls of red text, so I decided to make error handling more intuitive, clear, and developer-friendly.

Django Mentor or Learning Partner in Taiwan

Learning Django in Taiwan was kind of hard to find a mentor or people to work with. I can barely find people that using Django or talking about it.
Currently, I'm learning it on my own, but I really happy to have a person that can talk to, even help me to check or discuss even just sharing the progress , so just wondering is there any people that were also into Django are in Taiwan.

Deploying Flask app with frontend

I have just created a Flask app to learn Flask and try out TailwindCSS. I want to deploy it for free (it’s a fun project so traffic will be almost zero). It has two Python files: the first contains the program logic that fetches user data using a GraphQL query and returns it, and the second contains the Flask code. For the frontend, I’ve used HTML/CSS, JavaScript, and TailwindCSS.I have not used any database in this program.
How can I safely deploy this app, so I don’t end up with a huge bill if a spammer attacks?

How can I remove CKEditor buttons on my page?

I'm trying to configure the flask ckeditor by removing some buttons and also to style it a bit. Right now I have this snippet in my html file:

<div class="mb-3">
{{ form.body.label(class="form-label") }}
{{ form.body(class="form-control") }}
</div>

At the end I have:

{{ ckeditor.load() }}
{{ ckeditor.config(name='body') }}

I'd like to remove the 'About CKEditor' button, is there a way to do this without custom js scripts? Is there a way to customize the color of the editor, its border etc..

'Django Spellbook' - Markdown Content Management System (my first library)

I wanted to show off the Django Library I've been working on!

https://preview.redd.it/n9rzz0rbrlxe1.png?width=1036&format=png&auto=webp&s=9bad311c3ff9dde10761a59732223bdb646b4b96

Django Spellbook extends Django's templating and rendering capabilities with a focus on markdown-based content. It transforms markdown files into fully-rendered Django templates with auto-generated views and URLs, eliminating boilerplate code while maintaining Django's flexibility.

This website is powered by Django Spellbook: https://django-spellbook.org/

Here is the github: https://github.com/smattymatty/django\_spellbook (Stars are appreciated!)

I hope you like it I made it because I write a lot of markdown, and wanted a way to mix Django template language with simple markdown in a way where non-coders can contribute styled and user friendly interfaces for their content.

If you try the library, please report any bugs, issues, or feature requests! I plan on working on this for a while, I would like it to become a respected open-source library in the Django framework :)

Flask-based via telegram bot

I have built a secure and scalable Flask-based platform that integrates with a Telegram bot to streamline photo uploads into an online album.
Users can seamlessly create categories and assign photos directly through the bot interface.
All interactions are safeguarded with a robust authentication flow, requiring username, password, and TOTP (Time-based One-Time Password) verification to ensure high-level security and user integrity.

Any more features or ideas you can suggest for me?
