I Made a VR Shooter in Python

I'm working on a VR shooter entirely written in Python. I'm essentially writing the engine from scratch too, but it's not that much code at the moment.

Video: [https://youtu.be/Pms4Ia6DREk](https://youtu.be/Pms4Ia6DREk)

Tech stack:

* PyOpenXR (OpenXR bindings for Python)
* GLFW (window management)
* ModernGL (modernized OpenGL bindings for Python)
* Pygame (dynamic 2D UI rendering; only used for the watch face for now)
* PyOpenAL (spatial audio)

Source Code:

[https://github.com/DaFluffyPotato/pyvr-example](https://github.com/DaFluffyPotato/pyvr-example)

I've just forked my code from the public repository to a private one where I'll start working on adding netcode for online multiplayer support (also purely written in Python). I've played 1,600 hours of Pavlov VR. lol

# What My Project Does

It's a demo VR shooter written entirely in Python. It's a game to be played (although it primarily exists as a functional baseline for my own projects and as a reference for others).

# Target Audience

Useful as a reference for anyone looking into VR gamedev with Python.

# Comparison

I'm not aware of any comparable open source VR example with Python. I had to fix a memory leak in PyOpenXR to get started in the first place (my PR was merged, so it's not an issue anymore), so there probably haven't been too many projects that have taken this route yet.

Most common Python linter, formatter?

I've been asked to assist a group which is rewriting some of its ETL code from PHP to Python. When I was doing python, we used Black and pypy for formatting and linting.

Are these still good choices? What other tools might I suggest for this group? Are there any good Github CI/CD which might be useful?

And any good learning/training resources to recommend?

This year starting a blog and writing about more tech related topics besides just developing hobby projects is on my bucket list.

Since I still see a lot of people not knowing about uv, and I adopted it pretty much asap, I decided to write a bit about it and hope other feel it helpful and might also join the journey.

OSS billing library based in SQL and Python

I just released the 0.1.0 of the project I’ve been working on called bframe. It’s a billing library that is built on top of duckdb and has a client written in python. The project is in active development and I’m looking for feedback!

Repository

Documentation


## What My Project Does

bframe connects to your database (or just files) and generates invoices, line items and the like based off of source data. The library doesn’t require a server and can be fully executed in process which makes it easy to run and test. bframe offers git like branching, time travel and extensive documentation making it a good fit for operators who want better control over their tools.


## Target Audience

bframe is a production application designed for developers and operators. The library supports subscriptions, usage based billing and more; meaning most software based businesses are a good fit.


## Comparison

The largest difference between bframe and alternatives is how we treat persistence. This library connects to an existing store (bring your own infra), while other solutions use their own storage. The approach bframe employs has all of the advantages of running your own infrastructure along with a few others: 

1. No server or internet connection is required which makes it

Adding Metadata-Driven User Defined Fields. Will This Work?

In my Loan Origination System project, I have various models with predefined default fields. When a given institution integrates its data, I'm cognizant that each different institution is likely to have its own user-defined fields that won't have a (key-value) match to the default fields.

I need to be able to allow system admins to make use of their user-defined fields on the front-end. Additionally, allowing the ability to create new user defined fields within the system, for data they may want stored in the application but not necessarily on their core. Ideally, I'd accomplish this without substantially changing the structure of each model and changes to the schemas.

I realize I could just add a single JSON field to each model. However, wouldn't I then be required to handle validation and field-types at the application level?

Instead, will something like this work? Are there better approaches?

from django.db import models
from django.contrib.contenttypes.fields import GenericForeignKey
from django.contrib.contenttypes.models import ContentType

FIELDSOURCECHOICES = (
    ('integration', 'Uploaded/Integrated'),
    ('internal', 'Admin/Customer-Created'),
)

I created a simple mailing program; pymailer

# What My Project Does

pymailer is a simple program the uses SMTP and IMAP to connect to your gmail account to send and fetch emails.

# Target Audience

No one in particular, I made this mainly because I need it for my other projects. I just thought it would be cool to share.

# Comparison

I'm sure there are many mailing programs written in python and other languages but I think mine is pretty simple and easy to understand.

My first steps with Playwright

In my previous company, I developed a batch job that tracked metrics across social media, such as Twitter, LinkedIn, Mastodon, Bluesky, Reddit, etc. Then I realized I could duplicate it for my own "persona". The problem is that some media don’t provide an HTTP API for the metrics I want.

I searched for a long time but found no API access for the metrics above. I scraped the metrics manually every morning for a long time and finally decided to automate this tedious task. Here’s what I learned.

MStock: The Tool I Built to Track Macy’s Restocks 🛍️

Hey everyone 👋



I wanted to share a personal project I made: MStock. I kept running into the same problem—I wanted multiple items from Macy’s that were out of stock, and I was tired of constantly checking for updates. So, I built this tool to notify me the moment something comes back in stock!



What My Project Does

MStock is a Python tool that:

• Monitors Macy’s Product Pages: Tracks multiple items at once.

• Sends Notifications: Alerts me via email or SMS (through iMessage on macOS).

• Provides Product Details: Like price, ratings, and reviews, so I don’t miss out on key info.

• Handles Failures Gracefully: Uses smart caching to keep product info even if a check fails.


Target Audience

If you frequently shop at Macy’s and hate missing out on restocks, MStock is perfect for you. It’s especially useful for anyone tracking multiple products or looking for a hands-off way to monitor stock status.



Why I Built It

There were a few items I really wanted, but they were sold out for weeks. I didn’t want to miss them when they came back, so I made MStock to handle the tracking for me. Now, I get a notification as soon as something is available again, and

MathSpell v0.1.0: Expanded Features and Test cases!

Hello everyone!


A couple of weeks ago I shared my first ever python package MathSpell \- a context-aware number-to-word conversion library built on the `spaCy` and `num2words` python library. After receiving valuable feedback I started working on some improvements. I really thought I could update it in a day, but days turned into weeks. Well, I've released an update with v0.1.0.

# What’s New in v0.1.0?

Expanded Features:

More Contexts Handled:
Quantities: "5 m/s" is now "five meter per second". Used the `unit_parse` library (which also uses `pint` under the hood) to achieve this.
Currencies: "$3.25" converts to "three dollars and twenty five cents".
Exponential Notation: "3e8" becomes "three times ten to the power of eight".
Fractions: "1/2" converts to "one over two". Also preprocessed to avoid datetime format (dd/mm/yyyy) confusion with the mathematical division sign.
Test Cases:
Added 26 new test cases with edge cases\~
I also added docstrings for better understanding!



# Target Audience:

Mainly me. But I was really happy to see that it was positively received last time! The main use case of this library is for data preprocessing tasks for applications such as

Flask - Hosting - Requests

Hey, I am currently using a simple Flask app with a basic database connection to store various inputs (spread across 5 tables). The app also includes an admin login with user authentication and database queries for logging in.

The app is hosted on a VPS with 2 vCores and 2GB of RAM using Docker, Nginx, and Gunicorn.

This project originated during my studies and is now being used for the first time. Approximately 200 requests (in the worst case, simultaneously) are expected.

I would like to test how many requests the server can handle and determine whether 2 vCores and 2GB of RAM are sufficient for handling \~200 requests. I’ve noticed there are various tools for load testing, but since the VPS is hosted by a third-party provider, I would need to request permission before conducting such tests (even if the load is minimal).

Perhaps I am overthinking this, as 200 requests might not actually be a significant load at all ? If you need any additional information, feel free to ask, I didn’t want to go into every tiny detail here.

Thanks for taking the time to read this!
