Introducing ZipNN: A Python Library for lossless Compressing tailored for AI Models
**What My Project Does:**
ZipNN is an open-source Python library that enables lossless compression of AI models, **reducing their size by 33% with BF16 format (yes, also Llama3.2)**. Effectively cutting down download times and easing the load on servers. The library integrates smoothly with Hugging Face, with just adding a single line of code. The decompression is fast and there are already compressed Models on Hugging Face that you can try right away and save time.
**Target Audience:**
ZipNN is developed for **AI researchers, data scientists, and software developers** who manage large neural network models. It is particularly useful for those seeking efficient ways to handle model size constraints in both academic and production environments. The library aims to facilitate better resource management without sacrificing the accuracy of AI models.
**Comparison with Existing Alternatives:**
**ZipNN is tailored for AI models (the NN stands for neural network)** and gives both a better compression ratio and speed.
For example, with BF16, ZSTD (the current state-of-the-art) saves 21%, while ZipNN saves 33%, and compression and decompression are x1.5 faster.
**Additional Resources and Examples:**
* **GitHub Repository:** [Visit the ZipNN GitHub Repository](https://github.com/zipnn/zipnn)

Software Engineer Jobs database 9/25: Weekly posts of recently posted software engineer roles
Hey friends, every week I search the internet for software engineer jobs that have been recently posted on a company's career page. I collect the jobs, put them in a spreadsheet, and share them with anyone whose looking for their next role. All for free.
This week is the biggest job list I’ve curated to date. Over 150 roles from Software Engineering to Infrastructure Engineering, and includes opportunities across the globe. Due to popular demand, we’ve expanded beyond the USA to feature roles in Europe, South America, and Asia.
I hand pick the ones I know are good roles, with market salaries, and no glaring flags (ex: I generally only put roles with posted salary bands). Though its not easy to tell if the roles require leetcode or not.
The data is sourced by my own web scraping bots, paid sources, free sources, VC sites, and the typical job board sites. I spend an ungodly amount on the web so you don't have too!
About me, I am a senior software engineer with a decade of work history, and ample job searching experience to know that its a long game and its a numbers game.

Major Update: Simplify HTTP Security Headers in Django with secure.py
Hi Django developers,
A major update to secure.py has been released—a Python library that simplifies managing HTTP security headers in your Django applications. This release is a complete rewrite, leveraging modern Python 3.10+ features for better performance and usability.
Why Use secure.py with Django?
- Quick Setup: Apply BASIC or STRICT security headers with just one line.
- Full Customization: Control headers like Content-Security-Policy (CSP), HSTS, X-Frame-Options, Referrer-Policy, and more.
- Seamless Integration: Works smoothly with Django's middleware and view functions.
How to Integrate secure.py in Your Django Project
Middleware Example:
from django.http import HttpResponse
from secure import Secure
secure_headers = Secure.with_default_headers()
def set_secure_headers(get_response):
def middleware(request):
response = get_response(request)
secure_headers.set_headers(response)
return response
return middleware
set_secure_headers to your MIDDLEWARE list in settings.py.from django.http import HttpResponse
from secure import Secure
secure_headers = Secure.with_default_headers()
def home(request):
response = HttpResponse("Hello, world")
secure_headers.set_headers(response)
return response
Major Update: Easily Secure Your Flask Apps with secure.py
Hi Flask developers,
I'm excited to announce a major update to secure.py, a lightweight library that makes adding essential HTTP security headers to your Flask applications effortless. This latest version is a complete rewrite designed to simplify integration and enhance security for modern web apps.
Managing headers like Content Security Policy (CSP) and HSTS can be tedious, but they're crucial for protecting against vulnerabilities like XSS and clickjacking. secure.py helps you easily add these protections, following best practices to keep your apps secure.
Why Use secure.py with Flask?
- Quick Setup: Apply BASIC or STRICT security headers with just one line of code.
- Full Customization: Adjust headers like CSP, HSTS, X-Frame-Options, and more to suit your app's specific needs.
- Seamless Integration: Designed to work smoothly with Flask's request and response cycle.
How to Integrate secure.py in Your Flask App:
Middleware Example:
from flask import Flask, Response
from secure import Secure
app = Flask(__name__)
secure_headers = Secure.with_default_headers()
@app.after_request
def add_security_headers(response: Response):
secure_headers.set_headers(response)
return response
from flask import Flask, Response
from secure import Secure
app = Flask(__name__)
secure_headers = Secure.with_default_headers()
@app.route("/")
def home():
response = Response("Hello, world")
secure_headers.set_headers(response)

Sharing common code
Writing a Django rest API.
There are 3 apps within the project.
One of the functions I am using needs a database table to function.
I want to use that function in all 3 of the apps.
I am still developing that function as the app grows so I do not want to package that function at this stage.
Not sure how to achieve this.

(Almost) Pure Python Web App
A few weeks back I learned about htmx and quickly figured out that it actually allows you to do your frontend entirely in Python. So I decided to test if I can actually use it to make an SPA and how far can I go before i hit the limit. I spent a few weeks trying to create a messaging application (almost) entirely in Python. The end product is not exactly production-grade (there are minor UI bugs here and there), but I'm quite satisfied with it. This little project has allowed me to learn a great deal about htmx and its limits, and most importantly, it convinced me that htmx allows you to do quite a lot frontend stuff without having to touch JS.

Join the Bot Battle: Create Your Own!
Hey everyone!
I wanted to share a fun project I’ve been working on involving bots that play a game where they can choose to either share or steal. The rules are simple: if both players share, they each get 10 points; if both steal, they each get 0; and if one shares while the other steals, the stealer gets 20 points.
I've implemented a few example bots, including one that always steals and another that always shares. But I encourage all of you to create your own bots with unique strategies! You can modify their behavior based on past choices, implement more complex decision-making algorithms, or even create entirely new strategies. The possibilities are endless!
If you're interested, I’d be happy to share the code and discuss ideas for bot strategies. Let’s see who can create the most cunning bot!
Happy coding!

#1 steal
#0 split

PeepDB v0.1.4 - Support for MongoDB and SQLite added , GUI next time
# What My Project Does
I made a post a while ago about PeepDB. For people who don't know what the project is about, it is a CLI tool built in Python and my goal is to make it the easiest and fastest self hosted tool to view tables and data across multiple database types. I also want to make it a Python library so it can be used inside python scripts. Up until recently the project supported MySQL, MariaDB and Postgres databases.
# Target Audience (e.g., Is it meant for production, just a toy project, etc.)
peepDB is aimed at developers debugging database-driven applications, DBAs performing quick checks or audits, data analysts exploring table structures, and those learning about databases who want an easy way to explore data. It's suitable for use in both development and production environments
# Comparison
peepDB distinguishes itself from alternatives by focusing solely on quick table viewing, supporting multiple databases out-of-the-box. It requires no SQL knowledge to use, has a minimal footprint compared to larger database management tools
# What was added in this release
Because of popular demand support for MongoDB databases and SQLite, as well as enhanced security storage for passwords (not officially certified) and also the ability to switch between showing

What are your thoughts on using Django as an SPA backend?
I’m leaning more towards FastAPI, so try and change my mind!
For context, the frontend would be a Nuxt SPA with SSR. I like the Django admin and ORM, but building a REST API with Django just seems easier in FastAPI. I’d be using Django Ninja as I don’t want to pay for Django Rest Framework if I monetize the app (I can’t get past the “strongly encouranged to sign up for a paid plan” if the app is commercial).
Would you use Django or FastAPI for building the backend for an SPA?

Beginner Question - Why API?
I've recently been learning Django via tutorials and books solely as a personal challenge as I don't use coding in my career. That said, I am struggling to understand why REST API's (or API's in general), exist. I have created a blog API in a tutorial, but why? Beyond extracting data from a huge database, why isn't a regular website with data presented in html sufficient? As a corollary, what would be a good personal project that could utilize an API vs./on top of a standard django website?

Why use Django when we have FastAPI for small userbase applications
People often mention that Django comes with ORM and admin support. However, I can use SQLAlchemy or raw SQL queries as well. While Django has built-in admin features, FastAPI offers a full-stack template repository with React, which has pretty decent features that meet most requirements. FastAPI is also fast due to its asynchronous nature and has a growing, enthusiastic community eager to help.
Am I wrong in saying this? Give me good reasons to use Django.

It's a small project to see how far I can go building a dynamic web application without touching JS, using mainly htmx and Flask. It's an exploratory project to figure out the capabilities and limitations of htmx in building web applications. While it's not production-grade, I'm quite satisfied with how the project turned out, as I have learned a great deal about htmx from it.

Paramorator – Simplify Parametrized Decorators, Make Type Checkers Happy ✅
In almost every project I work on I end up needing to create parametrized decorators at some point. That is, a decorator that can accept arguments before you tack it into the function or class you want to wrap. For example:
@database_session
def get_data(session: Session, key: str) -> dict[str, Any]:
...
@database_session(privileges="read_write")
def save_data(session: Session, data: dict[str, Any]) -> None:
...
It's not exactly rocket science, but to do this in a way that will make type checkers and IDEs happy can be a bit of a pain. [Paramorator](https://github.com/rmorshea/paramorator) is a dead simple (<100 line) library I created that makes that process a little easier. Here's how you could use it to implement the `database_session` decorator above:
from functools import wraps
from typing import Callable, Concatenate, Literal, ParamSpec, TypeVar
from paramorator import paramorator
from sqlalchemy.orm import Session
P = ParamSpec("P")
R = TypeVar("R")
@paramorator

Looking for Advice: How’s the Job Market for Django Backend Developers?
I'm curious to know if there are any backend developers here who are using Django, DRF, Docker, AWS, RabbitMQ, Celery, etc. in their tech stack. If you're using this stack, how much are you earning based on your experience? What are your salary expectations?
Additionally, I'd love some guidance on compensation expectations as a fresher. I have experience working in production with this stack (internships and projects). What kind of salary can I expect as a fresher, and what should I aim for after gaining a few years of experience?
I’ve noticed that there seem to be a lot more opportunities for freshers in React, TypeScript, and Node.js compared to Django. While there are openings for Django, they’re often for senior roles. Would it be better to switch and focus on a different stack with more opportunities?
If you have experience with this stack, how has your career trajectory been? Any insights on pay scales or industry demand?
Thanks in advance!

WTF is ASGI and WSGI in python apps? - A writeup
I’ve been working on Python-based backend development for about three years now in various forms. I primarily use Django and FastAPI, although I initially started with Flask. However, during my backend work, I frequently encountered the terms ASGI and WSGI. For example, one of my Django deployment scripts included references to asgi_app and wsgi_app, and used gunicorn to deploy these apps. Although I initially dismissed these terms as implementation details but now got some time to go deeper. Here is a writeup:-
https://samagra.me/wtf/2024/09/27/gateway-interfaces.html
Edit TLDR:
ASGI and WSGI are protocols for communication between web servers and Python web applications. ASGI is newer, asynchronous, and more efficient for handling multiple requests simultaneously. WSGI is older, synchronous, and processes requests one at a time. The post explains their differences and provides example implementations of echo servers using both interfaces.
