Looking for working on a side project just for learning (without compensation is fine too)

Hi,
So I am a self-taught dev currently been working in the python eco-system with US start-up since past three years. However, my job is in intelligent automation domain (for which we don't use Django) and I have been kind of feeling stagnant on the professional front. Hence, just for learning sake I was wondering if some experienced person would want a fresher Django developer for any project. My goal here is simply to work under someone who could assign me tickets and most importantly review my submissions and provide feedback. I am not looking for any kind of monetary remuneration and am just here to learn.

I am willing to give 15-20 hours per week.

I have tried experimenting it on my own through videos building and breaking things on the side but wanted to experience things in a more professional setting. The feedbacks would be immensely valuable.

Any help in this direction? I'd be really grateful

Computers are fast Python perf quiz

I first encountered Julia Evans' Computers Are Fast performance quiz soon after it was published 10 years ago. It was so eye opening as a new programmer to get a few of the questions wrong by a 2-3 orders of magnitudes.

I wanted to update that quiz for 2024, swapping out Rust for C and fixing a couple of places where the 2014 quiz's Python 2 code does not translate directly and obviously into Python3.

Try it out and see how you go :)

R Understanding the Unreasonable Effectiveness of Discrete Representations In Reinforcement Learning

# Problem

Several recent papers in the model-based RL space [e.g. 1, 2, 3\] have used discrete state representations - that is weird! Why use representations that are less expressive and are far more limited in informational content?

That's what this paper looks at:

(1) What are the benefits of using discrete states to learn world models, and

(2) What are the benefits of using discrete states to learn policies?

We also start just start to look at why this might be the case.


# Key Results

1. World models learned over discrete representations were able to more accurately represent more of the world (transitions) with less capacity when compared to those learned over continuous representations.

ground-truth

continuous representations

discrete representations

Above you can see the same policy played out in the real environment, and simulated in continuous and discrete world models. Over time, errors in the continuous world model accumulated, and the agent never reaches the goal. This is less of a problem in the discrete world model. It's important to note that both have the potential to learn perfect would models

Why do people want to obduscate python code?

Over the last few months I have observed quite a few people asking how they can obfuscate python code.

Now, I understand why they'd want this. If you want to distribute your code for a payment, it would allow your users to not just copy it for free. But all the solutions for obfuscation where either "don't do it, make it a webapp" or reversible and slowed down the code.

But why would you even want to obfuscate python code and still run it using python? Wouldn't it be better to use smth like Cython or Nukita to convert your code to C and then create a binary? AFAIK that would still make your code unreachable while also making it faster.
Or are there any major drawbacks with that? One I could think of is that last time I used Cython numpy wasn't working properly. I havent used Nukita or other tools extensively enough to comment on them though.

Textchat: The SSL and SASL update

Hello all! I have posted in the past about Textchat, a TUI IRC Client made with textual that had a lot of bugs to it. I am back with an update: It now supports SASL and SSL! Again it's in alpha and bugs are still possible and bug reports are encouraged. Again here is the link: https://github.com/rmblau/textchat and it is available on pypi as well. Just a pip install away :)

# What My Project Does

As before, my project is a terminal application, single server irc client written with the python irc library and textual. No znc support presently.

# Target Audience

This is aimed at people who love irc as much as I do. Feedback is welcome and encouraged!

# Comparison

Nothing that I have found, as before.

RAW SQL over django ORM

So I came across a situation where I needed to join two tables on multiple columns that were not foreign keys. As far as I know, in django this could be done only using sub queries and outer refs. This creates significant performance issues comparison to the JOIN in a raw SQL query. Any thoughts on preferring raw SQL over django ORM?

[Showcase] G-Scraper - a GUI web scraper written completely in Python

**Target audience?** Basically data collectors or anyone trying to scrape data from websites using a GUI

**What my project does:**

* -Take URLs
* -Take elements to scrape from those webpages (this is optional in the sense that if you dont specify any elements the app will just scrape the entire page)
* -You can also send web parameters like Headers, Payloads along with specific URLs. This means it can perform any logins that are necessary
* -Is able to log the results in a log file, a separate one for each scrape
* -Data is stored in form of .txt files


**Some unique features of this project:**

* -Can scrape multiple URLs
* -Can scrape multiple elements in a single URL
* -Supports GET and POST requests
* -Scraping runs in a separate thread than the GUI, so you can close the app or use it and the scraping will continue
* -You can edit the added variables or delete them. You can also reset the entire app's current data to start a new set of scrapes
* -Very very unique filenames for each file created
* -3 types of log files: webpage scrape log, element scrape log and error log
* Has a

New to Django - some advice?

Hey all! I have read a lot about Django and decided to use this as the framework for full stack development (Django as backend, and simply using Bootstrap for frontend as a start) of a new application.

Other than the existing tutorials out there on how to start and build Django application, I am quite concern regarding the security aspect during deployment.

The application I intend to build is going to be a web facing application, with login to allow members to login and view their systems. Are there any good tutorials out there that teaches you how to secure a web facing Django?

By the way, I plan to deploy everything in AWS if it helps.

TIA.

Loop backwards using Django template over a slice

Hi,
currently facing a bit of an issue,
Im trying to simply iterate in a reversed order over a slice but the reversed filter doesnt seem to work in this case. As far as I understood, the reversed should be built in ? Thanks a lot

        <div>
            {% for i in game.board|slice:"6:12" reversed %}
                <a href="{% url 'make_move' forloop.counter0|add:6 %}" onclick="console.log('Pit clicked: {{ forloop.counter0|add:6 }}')">{{ i }}</a>

Is common best practice in python to use assert for business logic?


I was reviewing a Python project and noticed that a senior developer was using assert statements throughout the codebase for business logic. They assert a statement to check a validation condition and catch later. I've typically used assertions for testing and debugging, so this approach surprised me. I would recommend using raise exception.

First Time hosting

Hello and thank you in advance. I’m building a simple portfolio website that does not handle sensitive data besides a contact me email belonging to the owner and a log in system for editing images or text of the site. I am planning on deploying it to AWS lightsail and would love to get some tips or articles about security precautions I should take for the Django application, AWS lightsail, AWS account or any other part I should secure that is important.

low barrier-to-entry constraint satisfaction?

Say I've got a system of fairly simple relationships between (real number) variables: a = b + c, d = a*c, f = sqrt(a*b). Note there are implicit relations like c = a- b = f**2/b - b as well. Are there any ready to use libraries or modules that implement a constraint satisfaction network like this? I'd like the system start out without values assigned to any variables, but then the user inputs something like f = 3. This constrains the system now. If the user adds more values, at some point the system will be satisfied. As values are updated by the user, the system continue to ensure satisfaction, updating downstream values as necessary. I know this is generally a complex thing. I'd consider python-constraint but that is for finite-domains, and I'd like the system to support real number interval domains. Anyone know of some other similar projects out there?

Postgres VS MySQL?

Hello,

I came from PHP (Laravel) world and started to work with python and django only several months ago.

Since then, I see that PostgreSQL is much more popular than MySQL in django world. Are there any reasons for it beside of historic ones?

Should I switch my choice of DB to postgres or I can stay with mysql?

Qt (PySide6) or a Flask app running in a window for a modern, fluid desktop application?

(I know I'll probably get biased answers here, but you never know. You guys also might know something I don't yet that could influence my choice.)

Greetings.

To provide some context, I'm a 17-year-old intern at a very small startup -- so small that there are no adult employees, save for the founder and his son. The founder, our boss, was our AP Computer Science teacher (AP is an American program that allows high school students to learn college credit by taking a class and subsequent exam on content equivalent to an entry-level college course). He needed some help, so he offered unpaid internships to a few of us.

Anyway, my first task is to find a Python UI library. The founder is very adamant about using Python for this application -- I guess for its host of APIs and junk. (It's an application whose main functionality is a chatbot powered by the OpenAI API. I don't feel comfortable sharing any more details.) And, well, for a practical, modern, fluid, and responsive UI, I came to two options: PySide6, for its features; or Flask, for the ease-of-use of HTML, CSS, and JS, as well as Flask's simplicity, with a library to run a window in

What's the best way to mask auto-incrementing id field from end users? (read full post)

I've been using django-hashid-field for quite to mask the id field from frontend. The primary reason I am using that was

- I don't want to generate and store UUIDs in database column separately.
- I don't want to expose Auto-incrementing Primary keys to the end users.

Now the django-hashid-field package is retired, they recommend that everyone start using django-sqids.

Has anyone started using django-sqids in production? Are there any better alternatives?
