Looking for a Job Urgently.
Hey guys, i know this is not the place for this and i know its a long shot, but i think it is worth a shot.
my name is Goodluck, 20 years old.
i recently wrote my final exams in college, so i'm almost a college graduate in Computer science. i need a job as soon as possible. I'm proficient in python and can build flask apps. i am a fast learner, so the things i don't know, i can pick up on the job without being a burden or slowing down the workflow. i know some people would advice to get an official job, but i haven't been lucky enough to get one. Most of the ones i've seen on twitter were either closed or just scams to get me to create an account with the job application service. I've applied for a few and i got rejected in all.
I'm looking for a python backend entry/intern role. I've never really worked in a real life industry since i mostly learnt from tutorials on Youtube and torrent courses, but i know i can handle an intern role. I don't mind working as an assistant to someone and i don't

How to schedule a daily recurring function?
Hello everyone
So I built a basic backend and was wondering - how can I implement a function that has to run for example every day at 1pm?
Is there a classic way in Flask to do this?
Thank you very much!

Make-like task runner in Python
I made a complete Make-like build tool & task runner in Python.
I wanted to adopt Make's scheme of rules, targets, recipes, and dependencies mainly because it's simple, intuitive, and widely used.
Inspiration for the project came from using doit for similar tasks, and growing tired of the confusing API. There are other similar tools out there, but what I wanted was a lightweight, easy-to-use, flexible, and well documented task runner & dependency resolver for a data processing pipeline in Python.

Simple example & comparison with doit: https://stackoverflow.com/a/77752742

Best way to manage sockets with django
Hey, what is the best way to manage sockets with Django? I tried using Daphne, but it didn’t work well for me. It was working fine for a while, but then I had trouble restarting the Daphne server, even after restoring the configuration to the last working state. I’ve had enough of Daphne. Are there any good alternatives?

Example: Django + NextJS + JWT Authentication
https://github.com/kalvincalimag/django-nextjs-jwt-starter
/r/django
https://redd.it/1ez8v9l
Would a Django-Next.js-JWT Authentication Starter Kit be Useful?
I've been toying with the idea of putting together a Django-Next.js-JWT integration specifically designed for handling authentication. Here’s what I’m thinking: using Django Rest Framework (DRF) along with simple_jwt for the backend, complemented by a custom admin panel using Jazzmin. On the frontend, Next.js would be used purely for consuming this setup, focusing solely on authentication boilerplate.
However, I’m curious about your thoughts on this. Given the existence of NextAuth, I wonder if this effort might be redundant. Do you think there's still value in having a dedicated Django-Next.js-JWT starter kit for those who prefer a more tailored approach or need specific backend customization?
I'd love to hear what you think about this idea. Do you think it's worth the effort, or should I reconsider? Your thoughts would really help me out!

New Django Library: Django Action Trigger
It's been a while since I’ve shared something, but I’m excited to announce the release of a new Python library: Django Action Triggers.
This project is inspired by an older one I built a few years ago (django-email-signals). Django Action Triggers is a library that allows you to trigger actions based on database changes in your Django application.
It supports webhook integration and can send messages to brokers such as Kafka and RabbitMQ. You can easily set up actions to be triggered by specific events, all configurable through the front end.
What My Project Does
It allows you to configure triggers where a trigger is essentially watching out for some kind of database change. This is done using signals (post_save, pre_save, etc).
Alongside these triggers, you can configure some kind of action to take place. For now, this only will allow you to hit a webhook, or send a message to a message broker (RabbitMQ and Kafka supported).
Target Audience
At the moment, this is a toy project to get me comfortable write code that's supposed to be extensible again. However, would be nice if this eventually reaches production.
Comparison
From what I've seen so far, at the moment there isn't anything comparable unless you consider setting everything up

Django site ready - but having trouble deploying in azure as web app or docker (inexperienced)
Hey y’all! Been working on a project and ready to drop the MVP on azure for UAT. But even though I’m azure fundamentals certified I am lacking in the deployment department and can’t quite get my azure web app up and clearing a 200 status code. Looking for help or even a recommendation for experienced help to get me familiar with the process.
Here’s where I’m at:
1. Django project with 2 apps, email and Postgres DB, all working in dev
2. Have a “deployment.py” file that is referenced if os.environ() finds an azure host name, otherwise debug version of settings.py is used
3. Deployed the app via GitHub repo connected to azure. In the deployment logs I get a warning that “Django must be in the requirements.py file” but it is. No other errors seen
4. When accessing the webpage using the azure temporary url I get a 504 error.
5. I can’t troubleshoot much further since I can’t find where other logs are located and the documentation I have found is outdated and doesn’t match the current azure UI
Any help or leads for troubleshooting are appreciated! Please feel free to ask for more info if I haven’t provided it!

Okrolearn a machine learning library which is for powerful analzys and training while being light
I’m excited to share a project I’ve been working on called okrolearn. Which was created to allow for powerful analazys features and neural network training capabilities my own ideas while being as light as possible.
Target audience:
Machine learning enjoyers, mobile machine learning coders, data scientists.
Comparison:
Compared to things like pytorch or tensorflow it has better macOS support, better cpu usage, is way more light weight, is designed for lighter models, has features that these don't have,
What my project does:
* Trainin machine learning models
* Deploy models
* Is light
* Have analazys features such as correlation heatmaps, plotting kmeans, histograms, plotting losses, paramaters, etc.
* Manage layers for models, convolutional, l regularisation, batch, instance, dropout normalisers
* Have gpu support, custom kernels on gpu
* Have experimental features such as suggesting architecture and layers based on temperature and input data
* Have better macOS support
* Have better cpu performance
Why did I create this for simpler models or models that had to be lightweight tensorflow or pytorch didn't do a good job, I also wanted this library to be mainly in python, also converting pytorch tensors back to numpy arrays for me to analyse them was to slow and annoying, there were also ideas that I wanted to implement on

vectorized CIE distance in basiccolormath 3.0
[ShayHill/basic\colormath: Simple color conversion and perceptual (DeltaE CIE 2000) difference (github.com)](https://github.com/ShayHill/basiccolormath)
# What My Project Does
Everything I wanted to salvage from the [python-colormath](https://github.com/gtaylor/python-colormath/tree/master) library ... with no numpy deps and 14x speed.
* Perceptual (DeltaE CIE 2000) and Euclidean distance between colors
* Conversion between RGB, HSV, HSL, and 8-bit hex colors
* Simple, one-way conversion to Lab
* Some convenience functions for RGB tuples and 8-bit hex color strings
# Target Audience
Meant for production.
# vectorized functions
If you have numpy installed in your env, basic\colormath will provide vectorized versions of most functions.
|Function|Vectorized Function|
|:-|:-|
|float_to_8bit_int|floats_to_uint8|
|get_delta_e|get_deltas_e|
|get_delta_e_hex|get_deltas_e_hex|
|get_delta_e_lab|get_deltas_e_lab|
|get_euclidean|get_euclideans|
|get_euclidean_hex|get_euclideans_hex|
|get_sqeuclidean|get_sqeuclideans|
|get_sqeuclidean_hex|get_sqeuclideans_hex|
|hex_to_rgb|hexs_to_rgb|
|hsl_to_rgb|hsls_to_rgb|
|hsv_to_rgb|hsvs_to_rgb|
|rgb_to_hex|rgbs_to_hex|
|rgb_to_hsl|rgbs_to_hsl|
|rgb_to_hsv|rgbs_to_hsv|
|rgb_to_lab|rgbs_to_lab|
# Comparison
Sadly, python-colormath has been abandoned, long enough now that a numpy function on which it relies has been not only deprecated but removed. If you still need to use python-colormath, patch np.asscalar:
import numpy as np
import numpy.typing as npt
def patchasscalar(a: npt.NDArraynp.float64) -> float:
"""Alias for np.item(). Patch np.asscalar for colormath.
:param a: numpy array
:return: input array as scalar
"""

Beautiful Pancakes - A simple way to implement file writing and opening on PyQt's QGraphicsScene
Hey all!
# I am a relatively new Python programmer with experience in PyQt blah blah blah...
Anyways, when I was creating QGraphicsScene test files, I wanted to figure out a way to write QGraphicsItems to files, and then read those files to open them. This really doesn't exist for PyQt/PySide, as I have only found ways to do that in C++ Qt.
*So thats why I just finished Beautiful Pancakes today, [here's the repository\](https://github.com/ktechhydle/beautiful_pancakes).*
# What my project does
Implements file reading and writing for QGraphicsScenes with full support for file dialogs. PySide6 and PyQt5 supported.
# Target audience
It's great for basic to complex scenes, but I will try to update it and eventually make it work for advanced and performance heavy scenes.
# Comparison
There are alternatives, but most are written in C++. I have yet to find a PyQt version.
All serialization/deserialization is done in Pickle.
I hope you enjoy.

Celery is making me go insane
To preface this, I am using WSL2 Ubuntu in windows 11 for my development environment. I use visual studio code for my code editor.
I wanted to integrate Celery and Redis in a project I was working on, but I keep encountering this issue. Even if the task had already completed and is successful (based on Flower monitoring), when I try to retrieve the task result or task status in my flask app using AsyncResult and .get() it just loads infinitely and shows the status as PENDING and the result as NULL.
Now, I created a new stripped down flask app just to isolate the issue. And even with just a basic Flask app setup I am still experiencing it. I have been messing around with this for more than 48 hours now and it's driving me crazy.
Here are some code snippets from the stripped down flask app:
**\_\_init\_\_.py**
import os, time
from datetime import timedelta
from flask import Flask
from dotenv import load_dotenv
from .extensions import prepare_extensions, celery_init_app
load_dotenv()
app = Flask(__name__)
