Question about implementation of sending emails

I'm creating a web application following Miguel's mega-tutorial.
I'm on lesson 7 and I've encountered a problem: for some reason, despite having intentionally caused an error in my site, no message appears in the second terminal where aiosmtpd is running.
I don't understand why nothing appears. These are my bits of code that I used to try to make this stuff work:

in config file:

import os

basedir = os.path.abspath(os.path.dirname(__file__))  # Questa variabile immagazzina il percorso della directory principale sottoforma di stringa

class Config:
    SECRET_KEY = os.environ.get('SECRET_KEY') or b'mykey'
    SQLALCHEMY_DATABASE_URI = os.environ.get('DATABASE_URL') or \
        'sqlite:///' + os.path.join(basedir, 'app.db')
   
    MAIL_SERVER = os.environ.get('MAIL_SERVER')
    MAIL_PORT = int(os.environ.get('MAIL_PORT') or 25)
    MAIL_USE_TLS = os.environ.get('MAIL_USE_TLS') is not None
    MAIL_USERNAME = os.environ.get('MAIL_USERNAME')
    MAIL_PASSWORD = os.environ.get('MAIL_PASSWORD')
    ADMINS = ['mymail@example.com']

Spend lots of time and effort with this python project. I hope this can be of use to anyone.

https://github.com/irfanbroo/Netwarden

What my project does

What it does is basically captures live
network traffic using Wireshark, analyzing packets for suspicious activity such as malicious DNS queries, potential SYN scans,, and unusually large packets. By integrating Nmap, It also performs vulnerability scans to assess the security of networked systems, helping detect potential threats. I also added netcat, nmap arm spoofing detection etc.

Target audience

This is targeted mainly for security enthusiasts for those people who wants to check their network for any malicious activities

Comparison

I tried to integrate all the features I can find into this one script which can save the hassle of using different services to check for different attacks and malicious activities


I would really appreciate any contributions or help regarding optimising the code further and making it more cleaner. Thanks 👍🏻

Google Search introduced JavaScript

Has anyone figured out how to get data from the first page of Google search results now? Selenium?
BeautifulSoup seemed to do the job just fine (like getting headers of search results).
Now apparently a bare minimum would be Selenium to mimic user interface interaction.
But it still don't seem to accomplish that.
Although this is introduced:
driver.implicitly_wait(30)
and
profile.set_preference("javascript.enabled", True)

Overall it looks something like
profile = webdriver.FirefoxProfile()
profile.set_preference("general.useragent.override", "Mozilla/5.0 (X11; Linux x86_64; rv:38.0) Gecko/20100101 Firefox/38.0")
profile.set_preference("javascript.enabled", True)
broswer = webdriver.Firefox(profile)
broswer.get('https://Google.xyz xyz xyz')
driver.implicitly_wait(1000)

soup = BeautifulSoup(driver.page_source,'html.parser')
print(soup)

Is that suffice? Or supposed to be suffice?

Lost $25k usd and access to my web app

I have a Django Web Application built on 5.0.6

I was "partnered" with an individual. This individual more or less has stripped me of a little over $25,000 in revenue, has added another developer to the hosting platform (DigitalOcean).

I reached out to DigitalOcean explaining the situation and they said their was nothing they could do without details I don't have access to.

Lesson learned the hard way.

I spent around 9 months building this project from nothing. I have reached out to a lawyer and the lawyer has verified that I do own 100% of it. (I just wanted to be certain.)

I've exhausted every method I know to get administrative access back but I've ran out of options. I created a script in one of the app.py files to create a new user and promote them to superuser. The new developer turned off autodeploy from my repo so I cant modify it the actual django app that is running anymore.

How can I create an admin account without console access?

What should I do?

I've tried everything I know.

Please help.

Lawyer said to go ahead and file a DMCA Claim to DO. Lawyer will contacting the parties in the AM. I appreciate everyone's

Super Simple Python From Anywhere Task Runner

https://github.com/Sinjhin/scripts

What my project does

I whipped this up real quick for myself.

Seems pretty powerful. After I was done I took a brief look around realizing I could have just used someone else's tool and didn't immediately see anything like this. It's a bit opinionated, but essentially lets you use python scripts from a directory from anywhere on your computer. Could replace bash/zsh if you wanted.

After setup, you make a python file. Add a Poe task to pyproject.toml and then you can do `p <poe_task>` from anywhere. Has an example of getting different location relative to where the script was ran. Also has an `hp` command to get into a set conda venv and run a Poetry command within that scripts dir like `hp add torch`.

Could be expanded on a lot actually.

Target audience

Anyone who finds themselves constantly writing little utility functions to use around their computer and needing a quick way to run them from anywhere.

Comparison

I looked briefly (after the fact) and saw things like Invoke or Fabric, but I am not sure that they handle venv switching.

Django Channels: Asynchronous Magic for Real-Time Applications 🚀

Ever wondered how to build real-time features like chat applications, notifications, or live updates in your Django project? Django Channels makes it possible by bringing asynchronous capabilities to Django.

I’ve been working on this Django-Channels repository to make it easier for developers to understand and implement these real-time features. 🎯

Are there any TUI python debuggers? I found a couple hobby projects but they seem WIP/unmaintained.

Ideally, it should replicate vscode debugger like being able to watch expressions etc.

Day 2: Building Expense Tracker App

Hey everyone 👋


I'm currently working on an Expense Tracker App to learn how to display data on graphs using Chart.js. It's been a fun project so far, and I've made a few updates:

1. User-friendly interface: I focused on creating a more intuitive experience to keep users engaged.
2. Dismissible messages: Users are now better informed about their post progress with helpful notifications.
3. Robust error handling: Errors are now handled gracefully, preventing any app crashes.
4. Data persistence: Users won’t have to re-enter data when they encounter an error — it's saved for them!

This project has been a great opportunity to focus more on UI/UX instead of my usual backend-heavy approach, and I’ve learned a lot in the process.

View project on GitHub

If you're new to Django or looking for a fun project, why not give this a try? You’ll find a full description in the repo.

I have tried listening on my laptops hotspot interface (192.168.137.1) and all interfaces (0.0.0.0) when listening on all interfaces my hotspot interface does not appear in the list. Is there a way to resolve this? Would this application work on the hotspot from a Raspberry Pi?

Created a cool python pattern generator parser

Hey everyone!

Like many learning programmers, I cut my teeth on printing star patterns. It's a classic way to get comfortable with a new language's syntax. This got me thinking: what if I could create an engine to generate these patterns automatically? So, I did! I'd love for you to check it out and give me your feedback and suggestions for improvement.

**What My Project Does:**

This project, PatternGenerator, takes a simple input defined by my language and generates various patterns. It's designed to be easily extensible, allowing for the addition of more pattern types and customization options in the future. The current version focuses on core pattern generation logic. You can find the code on GitHub: [https://github.com/ajratnam/PatternGenerator](https://github.com/ajratnam/PatternGenerator)

**Target Audience:**

This is currently a toy project, primarily for learning and exploring different programming concepts. I'm aiming to improve it and potentially turn it into a more robust tool. I think it could be useful for:

* **Anyone wanting to quickly generate patterns:** Maybe you need a specific pattern for a project or just for fun.
* **Developers interested in contributing:** I welcome pull requests and contributions to expand the pattern library and features.

**Comparison:**

While there are many online pattern generators, this project differs in a few key ways:

[D] Ever feel like you're reinventing the wheel with every scikit-learn project? Let's talk about making ML recommended practices less painful. 🤔

Hey fellow data scientists,

While scikit-learn is powerful, we often find ourselves:

* Manually checking for cross-validation errors
* Bouncing between Copilot, StackOverflow, and docs just to follow recommended practices
* Reinventing validation processes that need to work for DS teams and stakeholders
* Notebooks that become a graveyard of model iterations

I'm curious how you handle these challenges in your workflow:

* What's your approach to validation across different projects? Is there any unified method, or does each project end up with its own validation style?
* How do you track experiments without overcomplicating things?
* What tricks have you found to maintain consistency?

We (at probabl) have built an open-source library ([skore](https://github.com/probabl-ai/skore)) to tackle these issues, but I'd love to hear your solutions first. What workflows have worked for you? What's still frustrating?

Django security best practices for software engineers.

Hi all,

I'm Ahmad, founder of Corgea. We've built a scanner that can find vulnerabilities in Django applications, so we decided to write a guide for software engineers on Django security best practices: https://corgea.com/Learn/django-security-best-practices-a-comprehensive-guid-for-software-engineers

We wanted to cover Django's security features, things we've seen developers do that they shouldn't, and all-around best practices. While we can't go into every detail, we've tried to cover a wide range of topics and gotcha's that are typically missed.

I'd love to get feedback from the community. Is there something else you'd include in the article? What's best practice that you've followed?

Thanks!

etl4py - Beautiful, whiteboard-style, typesafe dataflows for Python

https://github.com/mattlianje/etl4py

What my project does

etl4py is a simple DSL for pretty, whiteboard-style, typesafe dataflows that run anywhere - from laptop, to massive PySpark clusters to CUDA cores.

Target audience

Anyone who finds themselves writing dataflows or sequencing tasks - may it be for local scripts or multi-node big data workflows. Like it? Star it ... but issues help more 🙇‍♂️

Comparison

As far as I know, there aren't any libraries offering this type of DSL (but lmk!) ... although I think overloading >> is not uncommon.

Quickstart:

from etl4py import

# Define your building blocks
five_extract: Extract[None, int] = Extract(lambda _:5)
double: Transform[int, int] = Transform(lambda x: x 2)
add10: Transform[int, int] = Extract(lambda x: x + 10)

attempts = 0
def riskytransform(x: int) -> int:

PyPI security funding in limbo as Trump executive order pauses NSF grant reviews

Seth Larson, PSF Security-Developer-in-Residence, posts on LinkedIn:

> The threat of Trump EOs has caused the National Science Foundation to pause grant review panels. Critically for Python and PyPI security I spent most of December authoring and submitting a proposal to the "Safety, Security, and Privacy of Open Source Ecosystems" program. What happens now is uncertain to me.

> Shuttering R&D only leaves open source software users more vulnerable, this is nonsensical in my mind given America's dependence on software manufacturing.

> https://www.npr.org/sections/shots-health-news/2025/01/27/nx-s1-5276342/nsf-freezes-grant-review-trump-executive-orders-dei-science

This doesn't have immediate effects on PyPI, but the NSF grant money was going to help secure the Python ecosystem and supply chain.

Alternatives to session and global variables in flask

I currently am making an app that will query weather data from an AWS bucket and display it on a map. Right now I am using global variables to store progress data (small dictionary that records amount of files read, if program is running, etc) and the names of files that match certain criteria. However, I understand this is bad pratice for a web app. When trying to look for alternatives, I discovered flask's session, but my "results" variable will need to store anywhere from 50-100 filenames, with the possibility of having up to 2700. From my understanding this list of files seems like way too much data for a session variable. When I tested the code, 5 filenames was 120 bytes, so I think that its pretty impossible to stay under 4kb. Does anyone have any ideas instead? Once a user closes the tab, the data is not important (there are download functions for maps and files). I would perfer not to use a db, but will if that is outright the best option.
