Stockstir is a Python library that lets you get stock information from any script at no cost
Hello!
Just wanted to quickly showcase my project, Stockstir, which may be of use to many of you that want to follow stock prices freely in any script.
What My Project Does
Stockstir is an easy way to instantly gather stock data from any of your Python scripts. Not only that, but it includes other features, such as multi data gathering, anti ban, a fail-safe mechanism, random user agents, and much more.
Target Audience
Stockstir is for everyone that needs to gather realtime company stock info from any of their scripts. It mostly differs from any other stock related project in the way that it is simple, and doesn't rely on apis that cost money.
Comparison
Stockstir differs from other methods of gathering stock data in that it is has a very simple concept behind it. It is largely a GET wrapper in the Tools class, but initial API support such as Alpha Vantage, as well as gathering much more data of a Company stock through cnbc's JSON api, under the API class. It is mostly a quick way to gather stock data through simple use.
You can find installation instructions and other information under the project link provided below:

Report of big data. Experience stories
Good day🙋
Is there someone who works on a project where there's big data involved, i mean big database ( we use postgresql) where in one table for example, there is a lot of entries and there is a need of generating a report of them. For us we have celery and redis doing the work. The best part, It is not blocking the application but we are not very satisfied with the generation part. For example in order to generate a report of 10000 identifications, it takes around 20min. I would like to hear other stories and experience of dealing with generation of big report with a lot of data.

Time Series Analysis using First Return Time Statistics
Hi All,
I am currently working on a project focused on classifying chaotic and regular/quasi-periodic time series and am encountering some difficulties related to first return time statistics.
Some references suggest that for ergodic time series, the first return time statistics display an exponential decay, whereas this behavior does not generally apply to regular or quasi-periodic time series. However, I have observed that the Python code I implemented generates an exponential decay even for sin(t), which is a periodic function.
In light of this, I would greatly appreciate your insights on the general validity of the claim that first return time statistics exhibit exponential decay for ergodic time series but not for regular time series. Additionally, I would like to understand whether first return time statistics are an effective and sufficient method for analyzing the underlying dynamics of a time series. If so, I would be grateful for any suggestions regarding potential errors in my Python code (attached).

New to JWTs: How to Maintain User Login Beyond Token Expiration?
Hey everyone! I'm new to working with JWTs and have created a REST API that uses them for authentication, with a token validity of 15 minutes. As I integrate this API with a frontend framework, I'm facing a challenge: after the user logs in, the token expires after 15 minutes.
I want to ensure that users remain logged in indefinitely unless they explicitly log out. What are the best practices for handling JWT expiration? Should I implement a refresh token system, and if so, how should it be structured? Any guidance or examples would be greatly appreciated as I navigate this! Thanks in advance for your help!

How to navigate through file tree using url_for with flask buleprint?
I'm having trouble making my web app to read static style .css file when using flask blueprint. The HTML fails to read this stylesheet. I'm going describe how the project files are structured followed by the content of each files.
# Project structure
Below is the file structure tree:
main.py
coolestapp/
├── init.py
└── pages/
├── init.py

└── styles/
└── base.css
There are in total 5 files within this project. But, I'm only giving the content of 4 files only since the `.css` file content is irrelevant.
a. [`main.py`](http://main.py) file

Streaming HTTP Response Factory
In django I have a few API integrations that take a few seconds in a single HTTP request to finish. Rather than just letting the page spin, I decided it would be way better UX to send back "status updates" for each step.
Im using the StreamingHttpResponse and a custom factory I built. I'm trying to implement a few more solid design patterns in the app. So this is kind of practice, but also being used in prod. The way it functions is very similar to how ChatGPT's typed text is streamed back to the client.
Here's the code below:
# task_factory.py
class MyTaskFactory:
def __init__(self):
self.tasks = []
def _build(self):
return [task.build() for task in self.tasks]
def add_task(self, name):
task = MyTask(name, self)

Flask-JWT-Extended and "Invalid crypto padding"
Hi,
This is my first message on this subreddit.
I've been learning to write backend in Flask for some time now and now I'm trying to familiarize myself with using JWT in it. I have encountered a problem related to the use of the Flask-JWT-Extended library, and more precisely, when I try to send the generated token back, I get the error: "Invalid crypto padding".
It seems to me that token generation is done correctly but I could be wrong, below are some code snippets related to this.
@app.route('/login', methods='POST')
def login():
if request.method == 'POST': return logincontroller()
else:
return 'Method is Not Allowed'
def logincontroller():
requestform = request.json
print(requestform)
password = requestform['password']
try:
login = requestform'username'

Speeds up the query of a database with a lot of data
Hello everyone
I am working on an Oauth2 project App 1, one has a model company with 20 fields, when the user creates for example 20,000 company, when I created App 2 which can introspect App 1 and the model company , it takes 5 minutes for my request to return the companies to me and create or update them if they exist, I however used blinkcreate and blinkupdate when it is a new company, the others I update company by company is where the query takes a lot of time...
I also tried to overwrite the data received on the existing one, but my database or the Django ORM refuses because the foreight key already exists
Do you have any solutions when I update a list to do one by one and come update all at once?
Thanks to you

Feedback - Cyberbro - Analyze observable (IP, hash, domain) with ease - (CTI Cybersecurity project)
Hello there,
I am a junior cybersecurity engineer and I am developing an open source project in Python Flask and HTML.
Any feedback would be appreciated on the code structure, even if it actually works I think there are many improvements to be made (OOP, classes, I/O, MultiThread, MultiProcessing?).
I would be really glad to have a real Python programmer giving me even small pieces of advice to improve the project.
This project is a simple application that extracts your IoCs from garbage input (using regex) and checks their reputation using multiple services.
It is mainly Inspired by existing projects Cybergordon and IntelOwl.
I am convinced that this project is useful for SOC analysts or CTI professionnals (I use it daily for my job, and my company took interest for it).
**Features**
* **Effortless Input Handling**: Paste raw logs, IoCs, or fanged IoCs, and let our regex parser do the rest.
* **Multi-Service Reputation Checks**: Verify observables (IP, hash, domain, URL) across multiple services like VirusTotal, AbuseIPDB, IPInfo, Spur\[.\]us, IP Quality Score, MDE, Google Safe Browsing, Shodan, Abusix, Phishtank, ThreatFox, Github, Google...
* **Detailed Reports**: Generate comprehensive reports with advanced search and filter options.
* **High Performance**: Leverage multithreading for faster processing.
* **Automated Observable Pivoting**: Automatically pivot on domains, URL and

Summarized how the CIA writes Python
I have been going through Wikileaks and exploring Python usage within the CIA.
They have coding standards and write Python software with end-user guides.
They also have some curious ways of doing things, tests for example.
They also like to work in internet-disconnected environments.
They based their conventions on a modified Google Python Style Guide, with practical advice.
Compiled my findings.

Deploy Flask App
Hi everyone, I'm new to web app development and have created a Flask-based application that requests data from a PostgreSQL database, which is then updated on a Vanilla JS-based frontend.
Currently, the application is running on my local Windows environment, and want to publish it so it can be accessed by everyone on the internet. I'm finding it challenging to choose the right path and tools.
My company has a Windows server on Azure. Should deploy the app on an server, or is there a simpler, better approach? Any documentation or tutorials on the recommended deployment path would be very helpful.
