Django Javascript DX

Hi,


Long user of Django here, but recently developed mainly in React and Next JS.


I want to use Django + htmx (and maybe Alpine or vanilla js for some interactivity) for my next project. One thing I missing when using Django is intellisense/linter and good DX when it comes to templates and it comes to templates and javascript.

Templates

There are many ways to create components (include tag, Django cotton, etc..), but is there a way to get good autocomplete and intellisense, go to definition with cmd click etc.. for both the component name and the props that are passed to it?


Scripts

Is there a way to get imports, linter and autocomplete without involving webpack or another build step? For example, I have a main javascript file with functions that I add to my base HTML via script. But when I write js code specifically in the templates, I don't really have DX tools. In react world I'd import the main file into the component and get all of the DX tools.

Showcase: Recursive Functions To Piss Off Your CS Professor

I've created a series of technically correct and technically recursive functions in Python.

Git repo: https://github.com/asweigart/recusrive-functions-to-piss-off-your-cs-prof

Blog post: https://inventwithpython.com/blog/recursive-functions-to-piss-off-your-cs-prof.html

* What My Project Does

Ridiculous (but technically correct) implementations of some common recursive functions: factorial, fibonacci, depth-first search, and a is_odd() function.

These are joke programs, but the blog post also provides earnest explanations about what makes them recursive and why they still work.

* Target Audience

Computer science students or those who are interested in recursion.

* Comparison

I haven't found any other silly uses of recursion online in code form like this.

P Understanding Muon: A Revolutionary Neural Network Optimizer

https://preview.redd.it/oiupfzxptldf1.png?width=1536&format=png&auto=webp&s=ffc81d2aad36267e19040a2ce4515a933362690a


I just published a breakdown of Muon, the optimizer powering the new OS SOTA trillion-parameter model Kimi K2 and beating GPT-4.

💡 Why is Muon a big deal?

It rethinks how we optimize neural networks by treating weight matrices not just as numbers, but as geometric objects leading to 35% faster training with 15% fewer tokens.

Would love to hear your suggestions :)

Saturday Daily Thread: Resource Request and Sharing! Daily Thread

# Weekly Thread: Resource Request and Sharing 📚

Stumbled upon a useful Python resource? Or are you looking for a guide on a specific topic? Welcome to the Resource Request and Sharing thread!

## How it Works:

1. Request: Can't find a resource on a particular topic? Ask here!
2. Share: Found something useful? Share it with the community.
3. Review: Give or get opinions on Python resources you've used.

## Guidelines:

Please include the type of resource (e.g., book, video, article) and the topic.
Always be respectful when reviewing someone else's shared resource.

## Example Shares:

1. Book: "Fluent Python" \- Great for understanding Pythonic idioms.
2. Video: Python Data Structures \- Excellent overview of Python's built-in data structures.
3. Article: Understanding Python Decorators \- A deep dive into decorators.

## Example Requests:

1. Looking for: Video tutorials on web scraping with Python.
2. Need: Book recommendations for Python machine learning.

Share the knowledge, enrich the community. Happy learning! 🌟

Django 4.2 in 2025 still worth it?

Hi, trying to learn Python + Django and in some places like Coursera or Udemy. I see Django content is in 4.2 in a lot of places. Do you think still worth it to learn or should I look for some random tutorials in Youtube working with Djando 5.x?


My concern is mostly for deprecated content/functionalities


Thanks in advanced

D Advice on 10-min Ph.D. Interview Presentation (Bioinformatics)

Hi all,

I’ve been shortlisted for a Ph.D. position in bioinformatics in Spain, and I’ve been asked to give a 10-minute presentation during the interview. The topic is:

>

The research group is focused on QSAR, PBPK modeling, multi-omics integration, and predictive toxicology, so I want my presentation to reflect strong domain awareness — not just generic ML explanations.

Here’s what they expect me to cover:

How ML models are applied in this domain
Types of data involved (chemical structures, omics, assay outputs)
How models are validated
Current limitations or regulatory challenges

I’d really appreciate your thoughts on a few things:

1. How technical should I go, given it’s only 10 minutes?
2. Should I briefly include a case study like Tox21 or DeepTox for real-world relevance?
3. Would visuals like SHAP plots, ROC curves, or a workflow diagram help clarify things — or risk overloading the time limit?
4. Should I mention OECD acceptance of QSAR/ML models in regulatory toxicology?
5. Any advice to stand out as a good Ph.D. candidate through this presentation?

If you’ve gone through a similar interview — especially in bioinformatics, computational toxicology, or machine learning for biology/health — I’d love to hear how you approached your presentation.

Thanks so much!

My journey to scale a Python service to handle dozens of thousands rps

Hello!

I recently wrote this medium. I’m not looking for clicks, just wanted to share a quick and informal summary here in case it helps anyone working with Python, FastAPI, or scaling async services.

# Context

Before I joined the team, they developed a Python service using fastAPI to serve recommendations thru it. The setup was rather simple, ScyllaDB and DynamoDB as data storages and some external APIs for other data sources. However, the service could not scale beyond 1% traffic and it was already rather slow (e.g, I recall p99 was somewhere 100-200ms).

When I just started, my manager asked me to take a look at it, so here it goes.

# Async vs sync

I quickly noticed all path operations were defined as async, while all I/O operations were sync (i.e blocking the event loop). FastAPI docs do a great job explaining when or not using asyn path operations, and I'm surprised how many times this page is overlooked (not the first time I see this error), and to me that is the most important part in fastAPI. Anyway, I updates all I/O calls to be non-blocking either offloading them to a thread pool or using an asyncio compatible library (eg, aiohttp and aioboto3).

~~20~~ ~~22~~ 26 questions to check how well you can understand f-strings:

https://fstrings.wtf

> An interactive quiz website that tests your knowledge of Python f-string edge cases and advanced features.

> This quiz explores the surprising, confusing, and powerful aspects of Python f-strings through 20 carefully crafted questions. While f-strings seem simple on the surface, they have many hidden features and edge cases that can trip up even experienced Python developers.

> Remember: f-strings are powerful, but with great power comes great responsibility... and occasionally great confusion!

My first experience with Python

Okay I won’t go into much detail, but I’m a non-coder type. I am very technical-just don’t like coding basics mostly because of how my brain works. But I will say after spending 3-4 weeks in Python Hell trying to get things working; I will say this. Everyone who can get Python to sing has my utmost respect. I have never thought coding or programming was overly easy, BUT I now understand why coders and programmers want to throw computers across the room. It was one of the most frustrating and weird experiences of my life. So to the people who work in the Python/CSS area of coding. I tip my hat to you. Keep up the good work.

Suggestion needed for best AI helper for a (small) Django project

I'm stuck on my project since some time, on paper all scaffolding has been done, but I'm in the (bad) habit of losing too many hours on details and then the next working season starts, and... by the time I'm back I have to start all over again as I can't remember what does what and why.


What is in your experience the best among the various AI helpers, specifically for Django / Python language? I need something to delegate all boilerplate code so I can focus on the useful parts.

IDE is JetBrains, if that's useful to know... project is really basic, think a CRUD app, like a ticketing app with an extremely simplified asset management section.
