Pixel-map: A Python CLI tool for plotting geo files in the terminal

# What My Project Does

[**Pixel-map**](https://github.com/RaczeQ/pixel-map) displays geo data in the terminal. It can be used to quickly look into the geospatial data without opening generating HTML maps or using tools like [kepler.gl](https://kepler.gl/).

Anyone working on or with a great but little-known test framework?

If you're developing or enjoying a less popular testing framework with Python, I'd love to hear about it!

I don't love pytest, some of its complexities, tall decorator stacks, and function naming conventions.

I do love ward, with its unusual non-function-naming test names, and unusual defining-functions-in-loops for parameterization. Unfortunately it's now archived, as the developer is busy at Textualize.

Maintaining it myself is probably beyond my abilities and bandwidth, so I plan to migrate some projects to pytest soon, but wanted to check if anyone can show off some fun alternative with something special to offer.

Thanks for any contribution!

one year of peer review D

My manuscript has been in peer review for 10 and half months to ieee. The last time I contacted the journal to ask about the situation, they told me that they were looking for reviewers. It's been two months since the last email. I have no response from the journal. The manuscript is still in peer review. My question is, is it normal for it to take so long? Is this a good sign that my paper will be accepted? If it were the opposite, would they not hesitate to reject it directly or is it normal for it to take so long and then reject it in the end? The paper is about natural language peocessing

How do I solve this circular import error between two models ?

Here's a simplified to the maximum version of my code:

from app2.models import Model2

class Model1(models.Model):
model2 = models.OneToOneField(Model2, ondelete=models.CASCADE, null=True)


# In another app
from app1.models import Model1

class Model2(models.Model):
field1 = models.CharField(maxlength=90)

def save(self):
super().save()
objectmodel1 = Model1.objects.filter()
# Process on objectmodel1


In there, there are two models. One in each of two apps. Model1 needs to import Model2 to define a One To One relationship and Model2 needs to import Model1 because it needs to use it in its save method hence the circular import error I get. I could import Model1 in the save method of Model2 directly but I've read it is not recommended for multiple understandable reasons.

I also heard I could put the name of the model "Model2" in

Build a 'Chat with Wikipedia' App Using Flask and Gemini API (Demo + Code)

Hey Community,

I’m excited to share how quick and easy it is to bring your apps and ideas to life using Flask—the learning curve is really user-friendly! I recently built a "Chat with Wikipedia" app using Flask, powered by the Gemini API.

You can check out a demo on my YouTube channel (link provided in the video description), where you’ll also find the code.

Here’s a quick overview: this app lets you enter a Wikipedia page title and chat with the page to ask questions about it.

Next on my list is to develop a Chrome extension to extend this concept, making it possible to chat with any website directly.

Let me know what you think!

Project Open source video indexing/labelling/tag generation tool.

Guys, I'm looking for an open source tool or any repo that can help me generate tags for video to categorize multiple videos and do further analysis.

An equivalent of what I want is Azure AI clvideo inxer, but If there was such a open source tool, it will solve the problem.

A fun use of itertools in gamedev


For the last 3/4 years I've been working on this game in Python/Pygame

There's a lot of puzzling mechanics and tight movements required which got me to thinking of some hazards I could put in the game.

Anyway, fast forward a bit and I have one particular hazard which you can see here:

https://i.imgur.com/swY30rB.mp4

If that hurts your head, there's a simpler "up/down" version here

https://i.imgur.com/yE7LZGa.gif

While doing these I realised it was just cycling (a very obvious clue) through a list of different vectors. Which brought me to my favourite but often-unused module... itertools!

### itertools.cycle to the rescue!

When I saw this pattern I realised I could finally indulge myself and use itertools.cycle. I love the itertools modules but usually never get to use them in my day-to-day.

For those not in the know, itertools.cycle describes itself as this (paraphrased for brevity)

> Make an iterator returning elements from the iterable. Repeats indefinitely

In the first example we're just cycling through a version of a circle

datamule: download, parse, and construct structured datasets from SEC filings

Link: https://github.com/john-friedman/datamule-python

# What my project does

1. Download SEC filings quickly. (Bulk downloads are also available, benchmark is \~2 min/year for every 10-K/10-Q since 2001
2. Parse SEC filings quickly. (Currently only 8-K, 13F-HR Information tables are implemented. 10-K/10-Q coming next week)
3. Convert SEC textual filings directly into structured datasets.
4. Watch for new filings.
5. Has a basic tool calling chatbot with artifacts. Doesn't do anything useful yet, but was fun to make.

# Target Audience

Grad students looking to save money on expensive datasets, quants with side projects, software engineers looking to build commercial projects, and WSB people trying fun new trading strategies. In the future I'd like to make the chatbot code a bit cleaner so it can be used as a tutorial project for masters students w/ finance but not programming experience.

# Comparison

Getting SEC data in bulk is surprisingly expensive. Parsed SEC data is even more expensive. Derived datasets such as board of directors data is also expensive (something like 35k/license).

# Contribution

Greatly appreciated. Also SEC feature requests + QoL suggestions are very useful.

I created a Django rest framework package for MFA/2FA



I'm excited to announce the release of drf-totp, a package that brings Time-Based One-Time Password (TOTP) Multi-Factor Authentication (MFA) to the Django Rest Framework.

What My Project Does

drf-totp provides a simple and secure way to add an extra layer of authentication to your API endpoints, protecting your users' accounts from unauthorized access. With this package, you can easily integrate TOTP MFA into your Django Rest Framework project, supporting popular authenticator apps like Google Authenticator and Authy.

Key Features

1. Easy integration with Django Rest Framework
2. Supports popular authenticator apps like Google Authenticator and Authy

Target Audience

drf-totp is designed for developers and teams building secure API-based applications with Django Rest Framework. This package is suitable for production environments and can be used to add an extra layer of security to existing projects or new applications.

Comparison

While there are other MFA solutions available for Django, drf-totp is specifically designed for the Django Rest Framework and provides a seamless integration experience. Unlike other solutions that may require extensive configuration or customization, drf-totp is easy to set up and use, making it an ideal choice for developers who want to add TOTP MFA to their API endpoints quickly and securely.

Every unicode character can be a variable name in globals and locals

Hello. Reading about walrus operator I've seen φ used as a variable. That defied my knowledge (_, a-z, A-Z, 0-9), and I thought "if φ is valid, why 🍆 isn't?".

After a bit of try, I've come up with this.

initial = 127810
for i in range(10):
    variable = chr(initial + i)
    locals()variable = f"Value of {variable} is {ord(variable)}"
print(locals().get("🍆"))

Getting

Value of 🍆 is 127814

Therefore, 🍆 can be a variable in Python (in globals and locals). But also horizontal tab, backspace, null character, ... can be. Of course, they are not accessible in the code the same way than φ or hello_world, but still it's a nice gimmick. I hope you find it fun and/or useful.

But now the real thing. In this context, do you know if using backspace or null as a variable in globals could break the program in execution time? Thank you.

Hosting my Flask application - selecting a provider?

I'm currently looking to host my Flask application that is completely finished and just needs to go online, but as it is my first project that is actually going online I'm looking for some guidance with selecting a provider.

The app is a statistics application that I built for a company. It's a fairly basic Flask application with upwards of 8 .py scripts, a .json dataset and and some web templates, images and .css files. Everything is running smoothly and perfectly on the built-in development server, so I'm hoping it will continue to do so once hosted properly.

Security is a concern (if that matters when it comes to selecting the provider) as the application uses developer keys and some other credentials (that I've done all I can to secure within the app itself). I will need to install a log-in system of some sort so if any provider can make that easy that would be a major advantage.

Hoping for some pointers or just to hear some experiences with different providers - and thanks in advance :-)

P Shape-restricted regression with neural networks

Some time ago at work we had to enforce that our model learns an increasing function of a feature. For example, the probability of winning an auction as a function of the bid should increase. Recently, I encountered the paper https://arxiv.org/abs/2209.04476 on regression with shape-restricted functions, and wanted to make it a bit more tangible, with actual code that trains such a model.

So it resulted in a blog post: https://alexshtf.github.io/2024/10/14/Shape-Restricted-Models.html
There's also a notebook with the accompanying code: https://github.com/alexshtf/alexshtf.github.io/blob/master/assets/shape\_constrained\_models.ipynb

I used to work on ads quite a lot .So such models seem useful in this industry - predicting the probability of winning an ad auction given the bid. I hope it's also useful elsewhere.

So I hope you'll enjoy it! It's a big 'mathy', but you know, it can't be otherwise.
