How can I incorporate data science in Django project?

Hello, I’m working on a data science project for academic research. I need to do some data analysis (I mean, data acquisition, pre-processing and data processing), specifically, it is about natural language processing so I also need to train a machine learning model I can get an output I can put in a map (a Google map).

I’ve selected Django as the back-end framework I will use together with Flutter to develop my user interface for a mobile app in which I can deploy my map.

So, my question is how can I handle my data analysis code into the Django project so I am able to map the output of my analysis into my geographic map, that is to say: where do I have to put my data analysis logic in the Django project considering I am planning to save the data I retrieve externally into a database based on my models? and, consequently how can I store the analysis into the database?

Somebody told me about using microservices but, is that really necessary? In which cases are they used? And, can I manage this locally or what approach should I use to manage this data processing? at what point would I

Can I use both CPU and GPU cores simultaeneously?

I am currently working on an economic model using anaconda and Im kinda new to this.

The simulation is kinda slower than macbook m1 chips where it would take thrice the amount of time to complete the simulation

I am wondering if I can use both gpu (rx6600) and cpu (r7 5700x) to have as much cores for computing power.

5 months ago i asked which course to start django with ,now what's my next step ?

Greetings,

Five months ago, I created a post asking about how to start with Django. Months later, I completed a few courses, including a four-month ALX backend Django-focused course, and I made few basic API projects and few simple CRUD functionality projects using function-based views (FBV) and class-based views (CBV). Here’s one of my projects: https://github.com/Gamaljim/Fitness\_dj\_api (excuse the lack of a README or .gitignore file; I'm still learning how to properly set up a repo).

I'm 30 years old, stuck in a dead-end job in a country I don't want to be in, and I'm doing my best to study after work to shift my career and get back home as soon as possible. After finishing the course, I asked my instructor for feedback, and he said there’s still a lot to learn and that I’m not ready to apply for jobs yet. I understand this, but it did bring me down, and while I wouldn't say I'm depressed, I definitely feel low.

Now, to get to my question: What should I learn next? I've heard about CI/CD, Docker, Redis, and Celery, but these are foreign terms to me, and I don't know where and what to start with.

I hope you understand

Developing a Python-based Graphics Engine: Nirvana-3D

Hello community members,

[Crossposted from: https://www.reddit.com/r/gamedev/comments/1gdbazh/developing\_a\_pythonbased\_graphics\_engine\_nirvana3d/ \]

I'm currently working in GameDev and am currently reading and working on a 3D Graphics/Game Engine called: Nirvana 3D, a game engine totally written from top to bottom on Python that relies on NumPy Library for matrices and Matplotlib for rendering 3D scenes and imageio library for opening image files in the (R, G, B) format of matrices.

Nirvana is currently at a very nascent and experimental stage that supports importing *.obj files, basic lighting via sunlights, calculation of normals to the surface, z-buffer, and rendering 3D scenes. It additionally supports basic 3D transformations - such as rotation, scaling, translations, etc, with the support of multiple cameras and scenes in either of these three modes - wireframes, solid (lambert), lambertian shaders, etc.

While it has some basic support handling different 3D stuff, the Python code has started showing its limitations regarding speed - the rendering of a single frame takes up to 1-2 minutes on the CPU. While Python is a very basic, simple language, I wonder I'd have to port a large part of my code to GPUs or some Graphics Hardware languages like GLES/OpenCL/OpenGL/Vulcan or something.

I've planned the support for PBR shaders (Cook-Torrance Equation, with GGX approximations of Distribution and Geometry Functions) in solid mode as well as PBR shaders with HDRi lighting for texture-based image rendering and getting a

🔮Blackjack Strategy Simulator: The Most Comprehensive Open-Source Tool for Blackjack Analysis! 🔮

The **Blackjack Strategy Simulator** is a powerful tool for simulating every possible blackjack scenario to help users find the best move in any situation.

## What My Project Does

It allows you to:

* **Generate custom basic strategy tables** for various rule sets, including card splits and surrender options.

* **Simulate and analyze expected value (EV)** to understand the profitability of different strategies.

* **Calculate the best possible action** for any hand, considering complex rules and deck compositions.

* **Create advanced strategies** that adapt based on card counting or pre-set strategies.

## Comparison to Existing Alternatives

The **Blackjack Strategy Simulator** stands out in a few key areas:

* **Customization:** Unlike many online blackjack calculators, this simulator allows users to configure various game rules, including the number of decks, dealer behavior on soft 17, and advanced options like card counting deviations.

* **Detailed Analysis:** The tool provides a more thorough analysis than most basic calculators, considering complex scenarios such as multiple splits and custom deck compositions.

* **Open-Source Flexibility:** As an open-source project, it is highly customizable, with support for additional strategies and rule sets. Existing alternatives often lack this level of flexibility and transparency.

This tool offers a detailed approach to blackjack analysis by simulating millions of hands with high accuracy and

Advice Needed: Developing AI-Driven International Flight Planner for College Project – API Suggestions?


I’m working on my semester-end project, which is an AI-driven International Flight Planner. The goal is to help users find the best flight options tailored to their preferences (budget, airline, layovers, etc.), while also providing useful travel info like visa requirements, layover accommodation suggestions, and booking recommendations based on past pricing trends.
Would really appreciate any input on API selection, as well as any insights on tech stack choices for a project like this. Thanks in advance!

I’m using Django for the backend and considering PostgreSQL for storing flight data. However, I’m still looking into APIs that can provide reliable flight and travel data. I’m especially interested in APIs with a free tier or trial access since this is a college project.

How to setup a permanent session in default Flask?

If I use Flask-Session to store session data server-side, it is as easy as passing SESSION_PERMANENT = False (not default Flask, unique to Flask-Session) to the app.config, then set the desired expiration time with , PERMANENT_SESSION_LIFETIME = desired_exp_time which is default Flask config.

If I use default Flask to store session data client-side, I need to set PERMANENT_SESSION_LIFETIME = desired_exp_time first, then state session.permanent = True in the request (ex. u/app.route), else I get this error: RuntimeError: Working outside of request context. The docs is somewhat unclear about how to implement, see here.

What I don't understand is how to setup the default Flask one. I tried to google, and found this in Stack Overflow. The accepted answer suggests setting it with before\_request, but I think why every request, we need to set session.permanent = True?

1. How to set permanent sessions in default flask properly? Where to set it?
2. Can you toggle permanent and non permanent session?
3. What should we do after session is expired? What about the session data?

How would you handle limits for Free Users without involving stripe?

I'm building the user functionality for my app and want to offer a free tier option with limited capabilities. What's the best way to implement usage restrictions for free users without involving payment processing?

The goals are to:

Allow free users to upload up to 3 photos per month and view up to 10 pages per day
Avoid requiring credit card information upfront, as that may deter signups
Track each free user's usage to enforce the limits

Some options I've considered:

Create a "Free" subscription plan with the desired limits, but set the price to $0. However, this would still prompt for a credit card which I want to avoid.
Add a "paid" boolean field directly to the User model. Set it to false for free users. Then track photo uploads and page views separately without involving subscriptions.
Have a UserUsage model that stores the user's monthly photo uploads and daily page views. Check this on upload/view attempts to enforce limits.

Do you have any other suggestions for tracking free user usage and limits without payment processing involved?

Beginner in Web Dev – Need Advice on Architecting a Website for a RAG System Chatbot (Using Flask/Python)

I’m building a simple chatbot website to deploy a Retrieval-Augmented Generation (RAG) system I’ve developed, and I need some advice on the architecture. The generator itself runs through an API, and my goal is to keep the setup efficient and fast. I’m experienced in ML but new to web development, so I’d love some pointers on how to structure this in a way that’s simple and effective.

If anyone has experience building a website for a RAG system, I’d love to hear about your architecture—especially how you set up and deployed the API for handling requests. Did you use something specific to optimize for speed and resource management? Any tips for handling responses and managing requests would be super helpful, especially for Flask/Python setups.
