Real-time application with Django
lately, I created a helpdesk app, I used Django rest framework and vue js
there is a chat app in this helpdesk and I have to use websocket for a real time experience with the chat
the problem is that I don't really know how I am supposed to do that
I've heard about django channels but I have no idea of how it works
Can somebody explain the role of a consumer, asgi and routing in all of this ?

PEP 810 – Explicit lazy imports
PEP: https://pep-previews--4622.org.readthedocs.build/pep-0810/
Discussion: https://discuss.python.org/t/pep-810-explicit-lazy-imports/104131
This PEP introduces lazy imports as an explicit language feature. Currently, a module is eagerly loaded at the point of the import statement. Lazy imports defer the loading and execution of a module until the first time the imported name is used.
By allowing developers to mark individual imports as lazy with explicit syntax, Python programs can reduce startup time, memory usage, and unnecessary work. This is particularly beneficial for command-line tools, test suites, and applications with large dependency graphs.
The proposal preserves full backwards compatibility: normal import statements remain unchanged, and lazy imports are enabled only where explicitly requested.

Someone said that Flask session can be easily hacked via console and, depending on the implementation, they can inject a user's detail to impersonate them. How real is this?

Logly 🚀 — a Rust-powered, super fast, and simple logging library for Python
What My Project Does
Logly is a logging library for Python that combines simplicity with high performance using a Rust backend. It supports:
Console and file logging
JSON / structured logging
Async background writing to reduce latency
Pretty formatting with minimal boilerplate
It’s designed to be lightweight, fast, and easy to use, giving Python developers a modern logging solution without the complexity of the built-in logging module.
Performance Highlights (v0.1.1)
File Logging (50,000 messages): Python `logging` 0.729s → Logly 0.205s (\~3.5× faster)
Concurrent Logging (4 threads × 25,000 messages): Python logging 3.919s → Logly 0.405s (\~9.7× faster)
Latency Microbenchmark (30,000 messages):
|Percentile|loggingPython |Logly|Speedup|
|:-|:-|:-|:-|
|p50|0.014 ms|0.002 ms|7×|
|p95|0.029 ms|0.002 ms|14.5×|
|p99|0.043 ms|0.015 ms|2.9×|
>
\> Note: Performance may vary depending on your OS, CPU, Python version, and system load. Benchmarks show up to 10× faster performance under high-volume or multi-threaded workloads, but actual results will differ based on your environment.
Target Audience
Python developers needing high-performance logging
Scripts, web apps, or production systems
Developers who want structured logging or async log handling without overhead
Comparison
Python logging: Logly is faster, simpler, and supports async background writing out of the box.
Loguru: Logly adds a Rust-powered backend for improved performance under high-load scenarios and better async file handling.
Structlog: Logly is simpler to

Flask performance bottlenecks: Is caching the only answer, or am I missing something deeper?
I love Flask for its simplicity and how quickly I can spin up an application. I recently built a small, course-management app with features like user authentication, role-based access control, and PDF certificate generation. It works perfectly in development, but I’m now starting to worry about its performance as the user base grows.
I know the standard advice for scaling is to implement caching—maybe using Redis or Flask-Caching—and to optimize database queries. I've already tried some basic caching strategies. However, I'm finding that my response times still feel sluggish when testing concurrent users.
The deeper issues I'm confronting are:
Gunicorn Workers: I'm deploying with Gunicorn and Nginx, but I'm unsure if I've configured the worker count optimally. What's the best practice for setting the number of Gunicorn workers for a standard I/O-bound Flask app?
External API Calls: In one part of the app, I rely on an external service (similar to how others here deal with Google Sheets API calls. Is the best way to handle this heavy I/O through asynchronous workers like gevent in Gunicorn, or should I be looking at background workers like Celery instead?
Monitoring: Without proper monitoring, it's hard to tell if the bottleneck is the database, my code, or the

I built Poottu — an offline, privacy-first password manager in Python
Hey everyone — I wanted to share a project I’ve been working on recently: **Poottu**, a desktop password manager written in Python.
# What it does
At its core, Poottu is meant to be a **secure, offline, local vault** for credentials (usernames, passwords, URLs, notes).
* Fully **offline by default** — no telemetry or automatic cloud sync built in
* Clean, minimal GUI (using **PySide6**)
* Groups/categories to organize entries
* Live search across title, username, URL, notes
* Entry preview pane with “show password” option
* Context menu actions: copy username, password, URL, old password, notes
* Timed clipboard clearing (after N seconds) to reduce exposure
* Encrypted backup / restore of vault
* Password generator built in
* Keyboard shortcuts support
# Target audience
Who is Poottu for?
* **Privacy-focused users** who do not want their credentials stored in cloud services by default
* People who prefer **local, device-only control** over their vault
* Those who want a **lightweight password manager** with no vendor lock-in
# Comparison
Most existing password managers fall into two camps: **command-line tools** like `pass` or `gopass`, and **cloud-based managers** like Bitwarden, 1Password, or LastPass.
CLI tools are lightweight and fully offline, but they often feel unintuitive for non-technical users. Cloud-based solutions, on the other hand, are polished and offer seamless cross-device sync, but

R New paper: LLMs don't have privileged self knowledge, which means we can efficiently train a General Correctness Model to predict the correctness of multiple models. Surprising or expected?
Quick paper highlight (adapted from TLDR thread):
Finds no special advantage using an LLM to predict its own correctness (a trend in prior work), instead finding that LLMs benefit from learning to predict the correctness of many other models – becoming a GCM.
\--
Training 1 GCM is strictly more accurate than training model-specific CMs for all models it trains on (including CMs trained to predict their own correctness).
GCM transfers without training to outperform direct training on OOD models and datasets.
GCM (based on Qwen3-8B) achieves +30% coverage on selective prediction vs much larger Llama-3-70B’s logits.
TLDR thread: https://x.com/hanqi\_xiao/status/1973088476691042527
Full paper: https://arxiv.org/html/2509.24988v1
Discussion Seed:
Previous works have suggested / used LLMs having self knowledge, e.g., identifying/preferring their own generations [https://arxiv.org/abs/2404.13076\], or ability to predict their uncertainty. But paper claims specifically that LLMs don't have knowledge about their own correctness. Curious on everyone's intuition for what LLMs have / does not have self knowledge about, and whether this result fit your predictions.

Snakebar — a tqdm-style progress bar that snakes across your terminal
## What My Project Does
Snakebar is a tqdm-like progress bar for Python. Instead of a plain horizontal bar, it draws a one-character snake that fills your terminal via a random space-filling curve.
It still reports percentage, iterations done, ETA, and rate (it/s), but makes waiting more fun.
## Target Audience
Anyone who runs long scripts, pipelines, or training loops — data scientists, ML engineers, researchers, developers with heavy ETL or simulations.
It’s meant as a lightweight library you can drop in as a direct replacement for tqdm. It’s production-ready but also works fine as a fun toy project in personal scripts.
## Comparison
Compared to tqdm:
- Same semantics (snake_bar works like tqdm).
- Still shows % complete, ETA, and rate.
- Instead of a static bar, progress is visualized as a snake filling the screen.
- Fits automatically to your terminal size.
## Installation
pip install snakebar
OneCode — Python library to turn scripts into deployable apps
# What My Project Does
OneCode is an open-source Python library that lets you convert your scripts to apps with minimal boilerplate. Using simple decorators/parameters, you define inputs/outputs, and OneCode automatically generates a UI for you.
Github link is here: https://github.com/deeplime-io/onecode
On OneCode Cloud, those same apps can be deployed instantly, with authentication, scaling, and access controls handled for you.
The cloud platform is here: https://www.onecode.rocks/ (free tier includes 3 apps, 1Gb of storage and up to 5 hours of compute).
OneCode allows you to run the same code locally or on the cloud platform (one code ;)). You can connect your github account and automatically sync code to generate the app.
# Target Audience
Python developers who want to share tools without building a web frontend
Data scientists / researchers who need to wrap analysis scripts with a simple interface
Teams that want internal utilities, but don’t want to manage deployment infrastructure
Suitable for production apps (access-controlled, secure), but lightweight enough for prototyping and demos.
# Comparison
Unlike Streamlit/Gradio, OneCode doesn’t focus on dashboards, instead it auto-generates minimal UIs from your function signatures. OneCode cloud is also usable with long running compute, big machines are available, and compute is scalable with the number of users.

Best or most common way to deploy Django web app?
Sometime around 2002 I had a Virtual Private Server (VPS) running Apache with static html files. I started throwing in PHP and JavaScript to make things a little more dynamic. I even had a MySQL DB for when members to login. I got out of the business around 2017.
Now just for fun, I've got another VPS and a little website just to play with. I've ripped all my CDs and want to have a web page (or a few) so anyone can search for songs or artists or albums. I'm only going to open this up to a few friends so I want to control it with login credentials. I've taken Udemy classes on full stack, React, node.js, Django, Docker, PostgreSQL, etc. There are so many choices now!
I plan to write it using Django and using sqlite3 as the DB. I plan to use Bootstrap CSS to make it look pretty. I don't think it will be too tough to make something look pretty good.
Now to deployment. When I've taken the classes, the deployment is always on some website (eg. pythonanywhere.com) and I'm not sure how to duplicate that on my own VPS. I've looked at using Docker

Clarifying a few basics on user onboarding experience (engineering wise) (rookie question).
I am trying to build a micro saas tool (backend Django, frontend react, auth using firebase)
During the onboarding I have a specific flow, which I want users to see only for the first time (i.e. when they sign up). I am using firebase for google and apple sign ups.
Question is --> How do I store the "new user" status? It really doesn't make sense to store it as a field in the model, storing it on the client local would not be a good idea either - because if they login from another device or delete cache then they would see the flow again. Any tips on how to handle these decisions? Thanks a lot!

Watch out for your commas!!!
You might already know the memes behind forgetting to end a line with a semi-colon (;).
And it's kind of funny how Python doesn't fall into this problem.
You should, however, watch out for not ending a line with a comma in this particular scenario.
This scenario being having a list that extends multiple lines vertically.
EXAMPLE_CONST_LIST = [
"main.py", # <------ Make sure there is a trailing comma
"__pycache__"
]
import os
EXCEPTIONS = [
"main.py" # missing a comma here
"__pycache__"
]
for file in os.listdir():
if file in EXCEPTIONS:
