Any state machine fans​ out there?​ Got any fun/awful stories?

I first started to appreciate finite state machines about 15 years ago when I was creating a custom radio protocol for low speed long distance links. Nothing too fancy, but the protocol had retries and acknowledgements. Like a tiny TCP stack.

About 8 years ago I became a state machine nerd out of necessity at work. Sink or swim. Although it was hectic, it pushed me to create a very useful state machine tool.

# The frickin huge LCD GUI

My first project at a new company was very ambitious for a solo dev. In a short amount of time, I needed to create a custom user interface for a 2x20 character LCD that had a lot of different menu pages. 107 pages in total, arranged into different hierarchies. Some of the menus were calibration and setup wizards. Some showed live data. Some were interactive and allowed editing parameters. Each of those 107 pages also needed to support multiple languages (English, German, Russian, Spanish).

A previous developer (that quit before I joined) had tried a data driven menu approach. They defined the entire menu layout and page transitions in data. This made perfect sense for a while until the client started adding tricky requirements

What Database should I use if I get to nearly 10k users?

If you were building a website with Django, would you stick with the Mysql bundled with Django to serve as database for over 10k users or use another DBMS?

ryp: R inside Python

Excited to release ryp, a Python package for running R code inside Python!

[https://github.com/Wainberg/ryp](https://github.com/Wainberg/ryp)

ryp makes it a breeze to use R packages in your Python projects.

**What My Project Does**

ryp is a minimalist, powerful Python library for:

* running R code inside Python
* quickly transferring huge datasets between Python (NumPy/pandas/polars) and R without writing to disk
* interactively working in both languages at the same time

**Target Audience**

Data scientists and engineers, bioinformaticians, Python package developers, ...

**Comparison**

ryp is an alternative to the widely used [rpy2](https://github.com/rpy2/rpy2) library. Compared to rpy2, ryp provides:

* increased stability
* a much simpler API, with less of a learning curve
* interactive printouts of R variables that match what you'd see in R
* a full-featured R terminal inside Python for interactive work
* inline plotting in Jupyter notebooks (requires the `noscriptlite` R package)
* much faster data conversion with [Arrow](https://arrow.apache.org/) (also provided by [rpy2-arrow](https://github.com/rpy2/rpy2-arrow))
* support for *every* NumPy, pandas and polars data type representable in base R, no matter how obscure
* support for sparse arrays/matrices
* recursive conversion of containers like R lists, Python tuples/lists/dicts, and S3/S4/R6 objects
* full Windows support

ryp does the opposite of the [reticulate](https://rstudio.github.io/reticulate) R library, which runs Python inside R.

Get clean markdown from any data source using vision-language models in Python

I have found that quality data preprocessing for LLMs from raw data sources can be an incredibly difficult task, so I'm sharing a new project I began working on this summer to solve this problem.

What My Project Does:

The package in question is an open-source project designed to simplify the process of scraping clean data from various sources (PDFs, URLs, Docs, Images, etc). Whether you're working with PDFs, web pages, or images, it can handle the extraction into a clean markdown format. Unlike traditional scraping tools, it is able to understand the context and layout of documents, thanks to vision-language models. It even handles complex tables and figures.

The beauty of The Pipe is that it's not just a black box. It's open-source so you can peek under the hood, understand how it works, customize it to fit your specific needs, etc. The Python library is quite thoroughly documented for this kind of stuff.

Comparison:

Look at existing Python packages for document scraping such as PyPDF2, Unstructured, PyMuPDF (fitz), PDFMiner, Tabula-py, Camelot, pdfplumber, and marker. While these tools are great at basic text extraction, they often struggle with more complex tasks like handling scanned PDFs, irregular data tables, tables that span multiple pages, and documents

CORS and CSRF Configuration for a Separate Frontend and Backend? Willing to Pay

I have a website I am working on that uses Django and Svelte. Django acts as an API using Django Ninja. The frontend uses Svelte's SvelteKit framework and makes API calls to the Django backed. I have already created a github repo to hopefully make this easier and quicker: https://github.com/SoRobby/DjangoSvelteCookieAuth/tree/main.

The site is intended to be hosted on Digital Ocean (DO) on potentially two separate domains. Example of this would be below, where the frontend and backend are on separate subdomains.

Backend: https://example-backend-8lntg.ondigitalocean.app/

Frontend: https://example-frontend-gbldq.ondigitalocean.app/


Issue: I have been experiencing CORS and CSRF related issues that I can't seem to resolve. The site will use cookie-based authentication.

I have reached my threshold and am willing to pay ($200, via paypal or venmo) the first person that is able to solve these issues without sacrificing security, while remaining on Digital Ocean and deploying as an app and not a Docker container.

----

More details about the problem:
On the backend in settings.py, I have configured CORS, CSRF Cookies, and Sessions.

I am experiencing an issue that I cannot resolve and it relates to an error message of Forbidden (CSRF cookie not set.). On the frontend in Svelte, inside the hooks.server.ts file, whenever the frontend page is loaded,

Cannot send JSON with template

I have a problem where it keeps escaping the quotation marks.

This is my code:

@app.route('/')
def home():
    gameslist = {"message": "Welcome to the Game Submission Page!"}
    dump = json.dumps(gameslist)
    return rendertemplate('index.html', initialdata=gameslist)

and in my html

    <noscript>
        const initialData = "{{ initialdata }}"
        console.log(initialData)
    </noscript>

Console.log(initialData) produces "{\&#39;message\&#39;: \&#39;Welcome to the Game Submission Page!\&#39;}" regardless if I use json.dumps or not.

When I try "{{ initial_data | tojson }}" (also with "| safe") I get "Unexpected token '{'" when using json.dumps and without json.dumps I get "Unexpected identifier 'message'"

What am I doing wrong? Thanks.

Looking for a Django package to quickly add a blog to my existing project

Hey everyone!
I'm currently running a Django project and would like to add a blog feature to it. Is there a package or app that I can install to quickly set up a blog? Ideally, I'd want something that is easy to integrate into my existing project and doesn't require a full rebuild. Any suggestions for good blog packages, or should I just build one from scratch? Thanks in advance!

Currently we have a base app with some swiping functionaility. We have a lot of features in mind that cater to the ENM community, such as group chats and a calendar where you can schedule dates. We also have other features that we feel are good to put in a dating up.

Currently our active team members are mostly from asia so it would be great to have someone from asia as well(though this isnt a hard requirement, just a preference.)

[P] Just-in-Time Implementation: A Python Library That Implements Your Code at Runtime

Hey r/MachineLearning !

You know how we have Just-in-Time Compilation? Well, I thought, "Why stop there?" So I created Just-in-Time Implementation - a Python library that writes your code for you using AI. Yes, really!

Here's a taste of what it can do:

from jit_implementation import implement

@implement
class Snake:
"""Snake game in pygame. Initializing launches the game."""

if __name__ == "__main__":
Snake()

# Believe it or not, this actually works!

I started this as a joke, but then I got carried away and made it actually work. Now I'm not sure if I should be proud or terrified.

# How it works:

1. You write a function or class signature and a docstring.
2. You slap the `@implement` decorator on it.
3. The implementation is generated on-demand when you call the function or instantiate the class. Lazy coding at its finest!

# Some "features" I'm particularly amused by:

* It's the ultimate lazy programming tool. The code doesn't even exist until you run it!
* You can define

In search of exemplars

There have been lots of "best practice" questions over the years, but I'm looking for exemplars.

Projects that are done so well that they are (or are approaching) the gold standard of Pythonic ideals.

What projects have you worked on, or encountered that exemplified the best of Python's aspirations? The ones you can point to and definitively say "Here! Do it like this!"

One Year of Python and Django - Need Some Guidance 🙏

Hey everyone! 👋

I’ve spent a year learning Python and another year mastering Django. Along the way, I’ve built skills in MySQL, HTML, CSS, JavaScript, GitHub, Django Channels, and Django REST framework. I’ve also done projects like an e-commerce site, a real-time chat app, To dolist, and CRUD apps.

Right now, I’m a self-taught backend developer with no one to guide me. I’ve applied to a lot of jobs but haven’t had any luck. Can someone help me out? 😊

Python 3.13.0 release candidate 3 released

> This is the final release candidate of Python 3.13.0

> This release, 3.13.0rc3, is the final release preview (no really) of 3.13. This release is expected to become the final 3.13.0 release, barring any critical bugs being discovered. The official release of 3.13.0 is now scheduled for Monday, 2024-10-07.

> This extra, unplanned release candidate exists because of a couple of last minute issues, primarily a significant performance regression in specific workloads due to the incremental cyclic garbage collector (introduced in the alpha releases). We decided to roll back the garbage collector change in 3.13 (and continuing work in 3.14 to improve it), apply a number of other important bug fixes, and roll out a new release candidate.
