betterconf: minimalistic Python library for your configs.

betterconf (better config) is a Python library for project configuration management.

# What my project does

It allows you define your config like a regular Python class, casting values, getting values from anywhere and anyhow.

# Features and drawbacks

betterconf is really lightweight: all you need is Python >=3.8, no other dependencies. betterconf has simple, easy-to-learn API, which'll give you no struggle. betterconf's API is rich, staying as simple as possible, giving you lots of tools. betterconf is fully covered by tests so it won't fall by unexpected reason.

But as anything it has its own drawbacks.

By default there is a support only for os.environ. Any other providers like .json, .toml and everything else is not included but really easy to write due to betterconf's rich documentation.

betterconf doesn't have any security features or anything, but they could be easy added by a user.

# Audience

betterconf is fully production-ready, available as on PyPi so on GitHub. It can be used at web APIs, CLI tools, bots, everything...

# Comparison

Betterconf is simple and not sophisticated. Other libraries can have deep features that betterconf doesn't, but in exchange it gives you an ability to code it yourself. So, betterconf is ultimately-pluggable.

Code example:

from betterconf import Config, field

I made GestureFlow to improve my productivity!


# What My Project Does

GestureFlow is an innovative application that enhances the traditional right-click functionality on computers by introducing a customizable radial menu. Here's what it does:

1. Radial Menu Activation: When you hold the right mouse button for a short duration (200ms), a circular menu appears around your cursor.
2. Quick Action Selection: Move your mouse in the direction of the desired action and release the button to execute it. No need for precise clicking on small menu items.
3. Customizable Actions: The menu includes common actions like Copy, Paste, Undo, Redo, and more. These can be easily customized or expanded in the code.
4. Visual Feedback: The menu provides clear visual feedback with hover effects and color changes, making it intuitive to use.
5. Cross-Platform Compatibility: GestureFlow works on both Windows and macOS, automatically adjusting its keyboard shortcuts for each platform.
6. Efficient Workflow: By combining multiple actions (e.g., "Select All + Copy"), it reduces the number of steps needed for common tasks.

# Target Audience

GestureFlow is designed for:

1. Power Users: Individuals who value efficiency and customization in their daily computer use.
2. Professionals: Developers, designers, writers, or anyone who frequently uses context-based actions in various applications.
3. Accessibility Enthusiasts: People interested in alternative input methods that

OpenSkill MMR Rating System Now Features Per Player Weights

What My Project Does

OpenSkill is a peer-reviewed multiplayer ranking and rating system you can use to implement matchmaking systems on top of. This rating system behaves "like" TrueSkill, but is full open source, and unencumbered by patents, or trademarks. TrueSkill (Microsoft's proprietary, and patented rating system), has had something similar to this feature called "partial-play" for a while now. Our implementation is fully typed, supports pypy, and cpython and has 100% test coverage.

So what's this new change? Well there are not many open source rating systems (at least that I'm aware of) that let you consider in-game player scores to be factored into the rating updates. Only got 1 kill while the rest of your teammates got 4 or 5 kills? The rating system will update it's beliefs about a player based on these metrics. This means faster convergence to your actual skill.

Target Audience

I hope this new feature is useful to the game development community, especially those making multiplayer games. There is a lack of support for the game development ecosystem in Python. So here's hoping, your next multiplayer game finds use of this project!

Comparison

Some alternatives include EloMMR, Glicko-2 and TrueSkill. All of these are lacking in some areas.

Unable to type texts to chatbot user input

Hey guys, first time posting here. I am trying to add a chatbot for the backtesting platform built with Flask and there is a button on the right side that toggles the sidebar. If the user clicks the button, it shows the sidebar with a chatbot. But I'm going through an unexpected bug and would be utterly grateful if you guys could help me out.

I'll add this link(https://stackoverflow.com/questions/78752558/unable-to-type-texts-to-chatbot-user-input) that I posted on StackOverflow with the HTML, CSS, JS codes, and app.py code.

# Expected Behavior

The user should be able to type texts into the chatbot user input field.

# Current Behavior

Currently unable to type texts into the chatbot user input field.

Is SQLAlchemy really that good?

I've read a lot about SQLAlchemy and it seems to get a lot of hate for bad documentation or poor performance. I heard Peewee is a good alternative that's much more optimized and easier to use. The question is though, why is SQLAlchemy still so popular and widely used in industry? I heard it's the go-to for startups who choose Flask for their projects.
Personally I work with raw SQL queries The only advantage of SQLAlchemy I can sense is when defining tables and data, it's much easier to make the change, while with raw queries, you must modify each query string statement individually. For projects that use many tables with tons of columns that might be exhausting. But if the performance concerns are true, how does SQLAlchemy get away with it?

Implemented Full-Stack Web App with Next.js and Django Rest Framework: Facing CSRF Verification Issues



Hey everyone,

I've recently developed a full-stack web application using Next.js for the frontend and Django Rest Framework (DRF) for the backend. For authentication, I used Simple JWT.

Everything was going smoothly until I encountered a problem with CSRF verification failures. It seems like my requests from Next.js to the Django backend are being blocked due to CSRF token mismatches. Here’s a brief rundown of my setup:

Frontend:
- Next.js
- Axios for making HTTP requests
- Integrated authentication using JWTs from the backend

Backend:
- Django
- Django Rest Framework
- Simple JWT for token-based authentication

The Issue:
When I make authenticated requests from my Next.js app to the Django API, I keep getting CSRF verification failed errors. I've tried several solutions, including adding CSRF tokens to the requests and configuring CORS settings, but nothing seems to work.

Has anyone faced similar issues or have any suggestions on how to resolve this? Any help or guidance would be greatly appreciated!

Thanks in advance!

R Protein language models expose viral mimicry and immune escape

We got accepted at ICML 24/ML4LMS workshop, so I thought i'd share :)
 "Protein Language Models Expose Viral Mimicry and Immune Escape"

TL;DR:

🧬 Research Overview: Viruses mimic host proteins to escape detection by the immune system. We used Protein Language Models (PLMs) to differentiate viral proteins from human ones, with 99.7% accuracy.

📊 Insights: Our research shows that the PLMs and the biological immune system make similar errors. By identifying and analyzing these errors, we gain valuable insights into immunoreactivity and potential avenues for developing more effective vaccines and treatments.

We also show a novel, explainable, multimodal tabular error analysis approach for understanding insights and mistakes made on any problem, letting us understand what characterizes the mistakes made by Deep learning Language models/PLMs .

Best IDE for teaching Python (task creation)?

Hey everyone,

As mentioned in the title above, I am lookiing for the best IDE to use which would allow for task creation for my students, it should allow for tests to be run on outputs. I am a high school comp sci teacher who has used Replit for a while, but the education component of Replit is going to be shut down in a few weeks. I was thinking of

- PyCharm used it as a student many years ago in university and I know you can create tasks, good debugging

- VSCode, for this option I would just give them a zip file and they would work within.

If there are any better suggestions I am all ears,

Thanks.

Finance Toolkit - Calculate 200+ Financial Metrics for Any Company

This project originates from the frustration I had with financial websites and platforms not listing how they have calculated their financial metrics and seeing deviations when going to platforms such as Stockopedia, Morningstar, Macrotrends, Finance Charts, Wall Street Journal and many more. The metrics shouldn't deviate but they do (sometimes quite heavily) which encouraged me to start this project.

The whole idea behind the Finance Toolkit is to write every type of metric down in the most simplistic way (e.g. see here) so that the only thing that matters is the data that you put into it. I've worked on this project for around a year or two now and it currently has over 200+ different metrics such as Price-to-Earnings, Return on Equity, DUPONT, WACC, Bollinger Bands, Williams R, GARCH, Value at Risk, CAPM, Jensen's Alpha and all Option-related Greeks (and many many more).

Does this pique your interest? Have a look at the project on GitHub here: **https://github.com/JerBouma/FinanceToolkit**

Using the Finance Toolkit is pretty simple, you can download the package by using:

pip install financetoolkit -U

Then for example to perform an Extended Dupont Analysis you initialise the Finance Toolkit and run the related functionality:

Chunkit: Convert URLs into LLM-friendly markdown chunks for your RAG projects

Hey all, I am releasing a python package called chunkit which allows you to scrape and convert URLs into markdown chunks. These chunks can then be used for RAG applications.

The reason it works better than naive chunking (for example split every 200 words and use 30 word overlap) is because Chunkit splits on the most common markdown header levels instead, leading to much more semantically cohesive paragraphs.

Are PyPI Trove Classifiers worthwhile to maintain?

Are PyPI Trove Classifiers worthwhile to maintain? From what I can tell, many of the classifiers are redundant to modern pyproject.toml entries. For example, the Python versions are typically specified by the requires-python = <version> entry. And so the Trove Classifiers specifying the Python version become something that needs to be manually maintained, which, at least in my case, means it'll almost certainly go out of sync.

Trove Classifiers also seem up to the package author when to apply which classifiers, without much in the way of guidelines as to when a classifier should be used. For example, it's unclear which cases the Framework :: Matplotlib should be applied to, since it might be a package that is dependent on matplotlib, extends matplotlib, or is just usually expected to be usually used in conjunction with matplotlib but is not explicitly dependent on it. I'm having a difficult time finding guides explaining what is expected in these cases. Most (though certainly not all) articles I can find about them seem to be from a decade ago.

With that previous point, it seems the classifiers are fairly arbitrary. Do many systems still heavily rely on these classifiers? For example, are search results related to
