ASP.NET and Django. What's the difference?
I'd like to say that I'm not looking for an answer about which one is better, but that's a lie. However, this is subjective for everyone.
If there are anyone here who has experience with both ASP.NET and Django, please share your impressions.
P.S. I searched, but if anyone made a comparison, it was years ago!

Which is the Best Django Course on YouTube in 2024 for Beginners?
Hey everyone!
I'm looking to dive into Django and start my journey as a Python developer. As a beginner, I'm hoping to find a free, high-quality Django course on YouTube that can walk me through the basics and help me build some beginner-friendly projects.
I've seen some options pop up, but it's hard to decide which one is the most up-to-date and beginner-friendly in 2024. If you've come across any YouTube creators or playlists that do a great job explaining Django from scratch, please let me know!
Bonus points if the course includes:
* Step-by-step tutorials
* Project-based learning
* Clear explanations of concepts like models, views, templates, and databases
Thanks in advance for your suggestions!

Bagels - Expense tracker that lives in your terminal (TUI)
Hi r/Python! I'm excited to share Bagels \- a terminal (UI) expense tracker built with the textual TUI library! Check out the git repo for screenshots.
# Target audience
But first, why an expense tracker in the terminal? This is intended for people like me: I found it easier to build a habit and keep an accurate track of my expenses if I did it at the end of the day, instead of on the go. So why not in the terminal where it's fast, and I can keep all my data locally?
# What my project does
Some notable features include:
Keep track of your expenses with Accounts, (Sub)Categories, Splits, Transfers and Records
Templates for recurring transactions
Keep track of who owes you money in the people's view
Add templated records with number keys
Clear and concise table layout with collapsible splits
Transfer to and from non-tracked accounts (outside of wallet)
"Jump Mode" Navigation
Fewer fields to enter per transaction by default input modes
Insights
Customizable config, such as First Day of Week
Comparison: Unlike traditional expense trackers that are accessed by web or mobile, Bagels lives in your terminal. It differs as an expense tracker tool by providing more convenient input fields and a

Django image storage inside media folder for a freelance project
I’m working on a freelance project for an alumni website that’s expected to have very low traffic. The client chose to deploy it on a very cheap shared Linux server, so performance will likely be slow. The backend is a Django app with features like a gallery section and events, meaning it will need to handle multiple photos. Since we’re not investing in object storage like S3, what are the downsides of storing images directly in the media folder on the server?

Right way to start with Django?
Hey, I know this question may seem obvious but I don't really know where to start.
I work in marketing, I use Python for web crawling and data analysis + I have some experience with HTML and JavaScript creating A/B tests in VWO and implementing tracking tools in GTM. I also have 2+ years of experience in SQL (mainly managing 50+ databases in BigQuery) and creating data transfers in Google Cloud (YT -> BigQuery or Google Ads -> BigQuery and so on).
I would like to focus more on Python and django (e.g. to be able to embed pandas reports in a dashboard for the rest of the team instead of taking screenshots of Jupyter notebooks etc.) but I don't know where to start. I'm quite good at programming console applications etc. in Python but Django seems like a very complicated subject that will require knowledge of additional topics.
So... if you were not a computer science student/programmer but had some knowledge of Python and IT - how would you approach learning Django? Maybe I'm underselling my skills but I don't feel very confident in my skills since I'm primary 40+ marketing guy.

Python isn't just glue, it's an implicit JIT ecosystem
Writing more Rust recently led me to a revelation about Python. Rust was vital to my original task, but only a few simplifications away, the shorter Python version leapt to almost as fast. I'd stumbled from a cold path to a hot path...
This is my argument that Python, through a number of features both purposeful and accidental, ended up with an implicit JIT ecosystem, well-worn trails connecting optimized nodes, paved over time by countless developers.
I'm definitely curious to hear how this feels to others.
I've been doing Python half my life (almost two decades) and Rust seriously for the last few years.
I love both languages deeply but the pendulum has now swung back towards Python not as I won't use Rust but as I feel my eyes are now open as to how when and how I should use Rust.

D Accepted NeurIPS 2024 paper claimed to be solving a novel problem as first work, but ignores 5 prior works
At NeurIPS 2024 I found a paper that got accepted that positions its main contribution in the form of “Existing algorithms for X ignore Y. We adapt algorithm Z for X to account for Y”.
On OpenReview I see that the reviewers in particular praised the novelty of the work, and recognised Y as an important aspect that had been ignored in the field of X.
Now the interesting bit: co-authors and I published a paper in Springer’s Machine Learning journal in 2023 that also proposes an algorithm for X that account for Y. We were also not the first to study the problem setting of X with Y: our paper’s related work section discusses 4 papers that have all proposed algorithms for X that account for Y. One is even from NeurIPS (2017), and the oldest one dates back to 2012 (an AAAI paper).
The authors of this 2024 NeurIPS paper completely missed all this prior literature and believed they were the first, and so did all the reviewers.
This week I e-mailed the authors of this NeurIPS 2024 paper and they acknowledged that these works (mine + the 4 others) indeed were all working on the same problem setting, mentioned that they

Data model
Hi there, fellows,
I have the feeling i am wasting a lot of time reading the documentation of the flask-sqlalchemy flask-sqlalchemy....#define-models without doing real progress.
I seek here some advices to reach my goal faster: load a pandas dataframe into a nice class like ExcelData()
I can already load an excel and display it via route and template, but i now want to save it into a DB via a class. My skills seems to be bloked at this step.
Any hints? Link? Template, Tuto? Indian YouTuber?

Async or new thread?
Hi guys my flask route is streaming and “yield”s data every 1 second to check if the client connection has been closed. Meanwhile I want the actual route handler logic to run.
Right now I create a separate thread in the route handler to run the actual logic then just have a while loop with yield “” in the main thread.
But this just seems so hacky since I have to terminate the child thread from the main thread if the client closed the connection and yield “” threw a generator exit error.
I saw that flask has an event loop and just wanted to check with you all and see if anyone has had experience with it. Obviously it’s a much better solution if it works. Thanks!

11 Python Boilerplate Code Snippets Every Developer Needs
Python's simplicity makes it a favorite among developers, especially in trending fields like AI, machine learning, and automation. But let's face it—repeating boilerplate code can be a drag. That’s where Python snippets come in!
From validating emails to shuffling lists, we’ve rounded up 11 essential Python boilerplate snippets to simplify your daily tasks and supercharge your workflow:
# 🔍 1. Validate Email Formats (Regex Simplified)
Use regular expressions to validate email strings efficiently:
pythonCopy codeimport re
def validateemail(email):
emailpattern = re.compile(r'^a-zA-Z0-9._%+-+@a-zA-Z0-9.-+\.a-zA-Z{2,}$')
return bool(emailpattern.match(email))
# ✂️ 2. Slice Strings & Lists Like a Pro
Access sub-elements directly without loops for cleaner code:
pythonCopy codemystring = "Hello, World!"
print(mystring[0:5]) # Output: Hello
# 🔄 3. Compare Words: Are They Anagrams?
Quickly check if two strings are anagrams with `collections.Counter`:
pythonCopy codefrom collections import Counter
def areanagrams(word1, word2):
return Counter(word1) == Counter(word2)

Use python to build mk Converter
🚀 Check out my URL/PDF/DOCX to Markdown Converter!
Hey fellow developers! 👋
I'm super excited to share a tool I've been working on that I think might make your life a bit easier. You know that annoying process of converting documents to Markdown? Well, I built something to handle that!
What does it do?
- Converts web pages to Markdown with just a URL
- Transforms PDF files to Markdown (using pdfplumber)
- Converts DOCX files to clean Markdown
- Lets you preview the rendered result right there
- Comes with copy/download buttons for quick access
I built it using FastAPI for the backend (it's crazy fast! ⚡) and kept the frontend super clean and simple. You literally just paste a URL or upload a file, hit convert, and boom! 💥 You've got your Markdown.
Why I made this:
I got tired of manually converting docs for my documentation work, and thought others might find this useful too. Plus, I wanted to learn more about FastAPI and document processing in Python.
Tech stack:
- FastAPI (because who doesn't love async Python? 🐍)
- pdfplumber for PDF parsing
- python-docx for Word docs
- marked.js for the preview
- Basic HTML/CSS/JS for the frontend
The code is open source, and I'd love to get your feedback or contributions!

How do you handle speeding up frequent reads on aggregations without redundancy risks?
I've built an internal tool for Estimating, Inventory, Schedule & Dispatch, Job Costing & Reconciliation at a construction contractor business. We're using postgres. Now that much of the operational functionality is there with proper normalization, I'm building out dashboards that do a lot of aggregation on deeply nested fields.
So the (possibly misguided/skill issue?) goal is to persist some aggregated values to distant parent model objects. But the values can never be out of sync!
I've implemented the new GeneratedField with db_persist=True in a number of places, which just simplifies some things, but as I understand it I can't use a GeneratedField to sum a value on a child related model.
So there's a few options I'm aware of, and I'm curious what you use in production environments where data validity and integrity is vital (this affects what people are paid, records for taxes, etc).
Side effects in the child model's `save()` method override
1. Slow on save
2. Error prone, No guarantees on data integrity
3. Tons of clutter and poor maintainability in models . py
Django Signals to update affected parent fields
1. Slow on save
2. Does this roll back

Need advice on reducing latency and improving throughput in Django app
Hey r/django community! I'm struggling with performance issues in my Django application and could really use some expert advice.
**Current Setup:**
* Django 4.2
* PostgreSQL database
* Running on AWS EC2 t2.medium
* \~10k daily active users
* Serving mainly API endpoints and some template views
* Using Django REST Framework for API endpoints
**Issues I'm facing:**
1. Average response time has increased to 800ms (used to be around 200ms)
2. Database queries seem to be taking longer than expected
3. During peak hours, server CPU usage spikes to 90%+
4. Some endpoints timeout during high traffic
**What I've already tried:**
* Added database indexes on frequently queried fields
* Implemented Redis caching for frequently accessed data
* Used Django Debug Toolbar to identify slow queries
* Set up django-silk for profiling
* Added select\_related() and prefetch\_related() where possible
Despite these optimizations, I'm still not getting the performance I need. My main questions are:
1. What are some common bottlenecks in Django apps that I might be missing?
2. Are there specific Django settings I should tune for better performance?
3. Should I consider moving to a different database configuration (e.g., read replicas)?
4. What monitoring tools do you recommend for identifying performance bottlenecks?
5. Any recommendations for load testing tools to simulate high traffic scenarios?
Thanks in advance for any help! Let me

🚀 Feature Friday: assertNumQueries!
Today's Feature Friday reaches back into Django's history for a small-but-powerful tool: assertNumQueries!
This method from TransactionTestCase helps you write tests that verify the number of queries made by a piece of code.
It is a great way to check DB performance and catch regressions or "n+1" issues (when you accidentally make a single DB query for every object in a loop instead of loading everything up front from the database).
You can pass a function to assertNumQueries, or use it as a context manager, as shown in the example below:
from django.test import TransactionTestCase
from .services import myfunctionthathitsthedb
class MyTest(TransactionTestCase):
def testdbperformance(self):
# called directly
self.assertNumQueries(7, myfunctionthathitsthedb)
# used as a context manager
with self.assertNumQueries(2):

Networking applications should not be opening sockets
From my first development project involving networking I was hooked. I also found some areas of networking software a bit unresolved. There was some strong modeling for people who make networking components but that seemed to peter out after the sockets library. Nobody seemed to have a good compelling way to bundle all that block I/O, byte framing, encoding/decoding, message dispatching etc into something that was reused from project to project.
I finally did something about this and have produced a software library. I also wrote a discussion paper that is the first link in the readme of the following github repo. The repo contains demonstration modules that are referred to in the other readme links.
Networking is not about sockets
Is there anyone else out there that has thought along similar lines? Has anyone seen something better?

After years of working with Django, I always postponed building my own personal site. Recently, I decided it was time, and that’s how eriktaveras.com came to life.
# What’s included?
Backend: Django to manage projects and a contact form with spam protection (rate limiting and content detection).
Frontend: Tailwind CSS for a clean design and Alpine.js for light interactivity.
Extras: Automatic Telegram notifications whenever someone submits the contact form.
I’m also working on adding a blog and still uploading more projects to the portfolio, so it’s very much a work in progress.
# What I learned
Using Tailwind CSS for quick, efficient design.
Combining Django with lightweight frontend tools like Alpine.js.
Building a secure contact form without relying on external services.
