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:

P Graph-Based Editor for LLM Workflows

We made an open-source tool that provides a graph-based interface for building, debugging, and evaluating LLM workflows: https://github.com/PySpur-Dev/PySpur

Why we built this:

Before this, we built several LLM-powered applications that collectively served thousands of users. The biggest challenge we faced was ensuring reliability: making sure the workflows were robust enough to handle edge cases and deliver consistent results.

In practice, achieving this reliability meant repeatedly:

1. Breaking down complex goals into simpler steps: Composing prompts, tool calls, parsing steps, and branching logic.
2. Debugging failures: Identifying which part of the workflow broke and why.
3. Measuring performance: Assessing changes against real metrics to confirm actual improvement.

We tried some existing observability tools or agent frameworks and they fell short on at least one of these three dimensions. We wanted something that allowed us to iterate quickly and stay focused on improvement rather than wrestling with multiple disconnected tools or code scripts.

We eventually arrived at three principles upon which we built PySpur :

1. Graph-based interface: We can lay out an LLM workflow as a node graph. A node can be an LLM call, a function call, a parsing step, or any logic component. The visual structure provides an instant overview, making complex workflows more intuitive.
2. Integrated debugging: When

Laravel Developer Inheriting a Flask App

Hey all - I've been writing web apps in Laravel pretty much exclusively for the past 10 years. I was hired on by a client who said their previous developer was bailing on them and taking his code with him and I had 3 weeks to recreate his work. I was excited for the challenge. Now they've made nice enough with the previous developer (paying him the $50k of back pay they owed him - red flag!) that he's going to give me the source for the existing app. Turns out it's written in Python/Flask.

They're giving it to me in an AWS AMI that I theoretically just spin up in a new environment and it's good to go - includes all the RabbitMQ stuff, cron jobs, apache setup, etc.

The kicker though is that they want me to sign on to support this thing for a year or more. I was excited about that part too when I thought it was something I was going to write from the ground up and know inside and out. Supporting somebody else's stuff in a stack I don't understand... different enchilada.

Anybody here worked in both Laravel and Flask that might have some insight

selfie-lib - snapshot testing *and* caching/memoization (useful for testing against genAI)

# What My Project Does

selfie-lib is a snapshot testing library ([docs](https://selfie.dev/py/get-started#quickstart), [source](https://github.com/diffplug/selfie)), with a few novel features. At its most basic, it functions like `print` but it writes into your sourcecode instead of the console. You write a test like this:

expect_selfie(primes_under(15)).to_be_TODO()

When you run the test, selfie automatically rewrites the test code by calling `repl()` on the result of `primes_under(15)`, e.g.

expect_selfie(primes_under(15)).to_be([2, 3, 5, 7, 11, 13])

Now that the method call is `to_be` instead of `to_be_TODO`, this will throw an `AssertionError` if the `primes_under(15)` call ever changes its output.

That's standard snapshot testing stuff, the other things it can do are

* save snapshots inline with the source code or on disk
* [https://selfie.dev/py/facets#harmonizing-disk-and-inline-literals](https://selfie.dev/py/facets#harmonizing-disk-and-inline-literals)
* you can use snapshots to cache/memoize the results of slow & non-deterministic APIs (e.g generative AI), and build other test infrastructure on top of that snapshotted data
* [https://selfie.dev/py/cache#example](https://selfie.dev/py/cache#example)

# Target Audience

**People who test their code with** `print`. Just replace `print` with `expect_selfie(...).to_be_TODO()` and you can turn that `print` into a repeatable test.

**People who are building applications with nondeterministic or slow components, such as generative AI.** You don't want to hit the model for every unit test on the

Advice for Landing an Entry-Level Django Developer Job Without Professional Experience

Hi everyone,

I’ve been learning Django for a while and have built a few personal projects to strengthen my skills. While I feel confident in my abilities, I don’t yet have professional development experience. Because of this, I’ve been struggling to land an entry-level or junior developer role.

I’d love to hear feedback or advice from seasoned developers or anyone currently working in the field. Your feedback and advice are truly priceless to me, and I deeply appreciate any insights you can share.

I’m planning to include my resume and a link to my portfolio in this post for reference. Any tips or suggestions on how I can improve them, or general advice about entering the field, would mean a lot to me.

Thank you so much for your time and help!

TypeScribe: A Python GUI App for organic Handwritten Text Generation with Machine Learning

Hey folks, just sharing a little side project I have been working on.

I was looking for a handwritten text generator, but since most of them rely on fixed fonts, the consistency becomes an obvious give away. So, I decided to build one on my own.

# TypeScribe v1.0

I'm excited to introduce TypeScribe, a program that converts text into organic handwritten text using a Recurrent Neural Network (RNN) trained on real handwriting samples. In documents generated with TypeScribe, every stroke, curve, and loop is unique.

What My Project Does

With TypeScribe, you can customize every aspect of the your handwritten documents including:

12 unique handwriting styles to choose from
Page, Line and Margin color customization
Page Dimensions
Ink Color, Pen Thickness Customization
Handwriting Consistency (Neatness)
and many more!

Target Audience

With TypeScribe, you can:

1. Create organic handwritten letters (in cursive!).
2. Fill in your notebooks!
3. Send out handwritten Christmas cards, just in time!
4. Add a personal touch to absolutely anything.

TypeScribe can automatically split large texts into multiple pages, and YOU get to specify how many lines to write per page!

When you create a document with TypeScribe, it generates an SVG file that can be scaled with zero loss in quality. All you have to do is paste

Py-Cachify 2.0 - Distributed Locks and Handy Caching Decorators

What My Project Does

Py-Cachify is a robust caching and locking library for Python applications. I recently published a significant 2.0 update introducing several improvements, including enhanced locking versatility, revamped documentation, automatically attachable helper methods, and more. This library simplifies the implementation of caching and locking, offering decorators to easily integrate these features into your code.


Target Audience

This library is ideal for developers looking to optimize their Python applications, whether for production use or personal projects. Its features cater to both novice and experienced Python developers.


Comparison

Py-Cachify focuses on the simplicity of cache and lock implementations, prioritizing ease and flexibility of use in any app over complex caching/locking strategies. One of its standout features is dynamic key generation based on function signatures without any external dependency, allowing you to cache function results with context-aware keys.

Additionally, it works in both synchronous and asynchronous environments and is fully type-annotated for enhanced IDE support.


The source code is on GitHub.

The new documentation is here.

Feedback and feature requests are appreciated!

What features should all flask apps have?

I've been programming for about a year and a half now and built a small flask app to manage my music business. Basically a management application with some API integration and sqlalchemy. The app now works fine and is stable, but I'm wondering if there are any features/functions/etc. that all flask apps should have implemented, that don't seem obvious to a beginner like me. Cybersecurity and complex algorhithms still go a bit beyond my understanding, but I wanna make my app as secure, stable and reliable as possible.

I built web app using Django!

Hello everyone 👋,

I just wanted to show off a web app I made using Django. Outside of tutorial projects, this is my first official project. It's called Salted Vanilla and it's a scented candle cataloging web app.

I used this tutorial by Kostja to start the project and I built from there. I'm using Appliku to deploy on AWS Lightsail. I used ChatGPT to help with model structure and relationships. I am using Django templates, a little Bootstrap, and most recently Bootstrap Studio for the front end.


Here is the git repo

Benchmark library that uses PostgreSQL

I am writing an open-source library that simplifies CRUD operations for PostgreSQL. The most similar library would be SQLAlchemy Core.

I plan to benchmark my library against SQLAlchemy ORM, SQLAlchemy Core, and SQLModel. I am unsure about the setup. I have the following considerations:

\- Local DB vs Remote DB. Or both?
\- My library depends on psycopg. Should I only use psycopg for the others?
\- Which test cases should I cover?
\- My library integrates pydantic / msgspec for serialisation and validation. What' the best practice for SQLAlchemy here? Do I need other libraries?

What are your opinions. Do you maybe have some good guidelines or examples?

My library is not yet released but quite stable. You can find more details here:
