🚀 Introducing TkRouter — Declarative Routing for Tkinter

Hey folks!

I just released TkRouter, a lightweight library that brings declarative routing to your multi-page Tkinter apps — with support for:

✨ Features:
- /users/<id> style dynamic routing
- Query string parsing: /logs?level=error
- Animated transitions (slide, fade) between pages
- Route guards and redirect fallback logic
- Back/forward history stack
- Built-in navigation widgets: RouteLinkButton, RouteLinkLabel

Here’s a minimal example:

from tkinter import Tk
from tkrouter import create_router, get_router, RouterOutlet
from tkrouter.views import RoutedView
from tkrouter.widgets import RouteLinkButton

class Home(RoutedView):
    def __init__(self, master):
        super().__init__(master)
        RouteLinkButton(self, "/about", text="Go to About").pack()

class About(RoutedView):
    def __init__(self, master):
        super().__init__(master)
        RouteLinkButton(self, "/", text="Back to Home").pack()

ROUTES = {
    "/": Home,
    "/about": About,
}

root = Tk()
outlet = RouterOutlet(root)
outlet.pack(fill="both", expand=True)
create_router(ROUTES, outlet).navigate("/")
root.mainloop()

📦 Install via pip

pip install tkrouter

DVD Bouncing Animation

* **What My Project Does:** Creates a simple animation which (somewhat) replicates the old DVD logo bouncing animation displayed when a DVD is not inserted
* **Target Audience:** Anyone, just for fun
* **Comparison**: It occurs in the command window instead of a video

(Ensure windows-curse is installed by entering "pip install windows-curses" into command prompt.

ChatForge: A free, open-source AI chat client with 300+ models (GPT-4, Claude 3, etc.)—no subscriptions, pay-per-token!

I’ve been working on ChatForge—a no-BS, open-source chat client that lets you access 318+ AI models (GPT-4.1 Mini, Claude 3.7, Qwen, Gemini, etc.) from one dashboard. No upfront costs, no monthly fees—just pay for tokens you actually use.

Why bother?

Free-tier models: Test drive without even adding a payment method.
Persistent chats: Name/organize convos like files (RIP losing your 2am AI rants).
Customizable: Set default models, API keys, etc.
Simple UI: Not a design award winner, but it’s clean and functional (I’m a dev, not a designer—sue me).

It’s 100% free and community-driven. I’d love feedback (or contributions if you’re into Python/Django).

Try it or roast it:

P.S. If you’ve tried similar tools (like OpenRouter’s web UI), how’s this compare? Honest takes welcome.

How would you handle achievements and achievement progress n a Django app?

I’m working on a Django web app where I want to introduce badges/achievements for users — things like:

* Play 10 random quizzes in a day
* Finish 100 quizzes in total
* Play 7 days in a row

Here’s the basic model setup I’m considering:
```
class Achievement(models.Model):
code = models.CharField(max_length=100, unique=True) # e.g., 'play_10_quizzes'
name = models.CharField(max_length=200)
description = models.TextField()
icon = models.ImageField(upload_to='achievement_icons/', null=True, blank=True)

class UserAchievement(models.Model):
user = models.ForeignKey(User, on_delete=models.CASCADE)
achievement = models.ForeignKey(Achievement, on_delete=models.CASCADE)
unlocked_at = models.DateTimeField(auto_now_add=True)

class Meta:
unique_together = ('user', 'achievement')
```

How best to save and calculate/track user progress toward an achievement?

I’ve been reading that using Django signals might not be the best approach here, and I’m wondering what patterns or architecture others have used.

**Specifically:**

* Do you calculate achievement progress dynamically (on the fly) when the frontend requests it?
* Or do you store progress in the database and increment it every time an action happens (e.g., quiz completed), so reads are faster?
* How do you handle edge cases, like historical data changes or deletions?
* Any tips on scaling this

Why should one write tests?

First of all I will not question whether it is necessary to write tests or not, I am convinced that it is necessary, but as the devil's advocate, I'd like to know the real good reasons for doing this. Why devil's advocate? I have my app, that is going well (around 50k users monthly). In terms of complexity it's definetely should be test covered. But it's not. At all. Yeah, certainly there were bugs that i caught only in production, but i can't understand one thing - if i write tests for thousands cases, but just don't think of 1001 - in any case something should appear in prod. Not to mention that this is a very time consuming process.


P.S. I really belive I'll cover my app, I'm just looking for a motivation to do that in the near future

strif: A tiny, useful Python lib of string, file, and object utilities

I thought I'd share **strif**, a tiny library of mine. It's actually old and I've used it quite a bit in my own code, but I've recently updated/expanded it for Python 3.10+.

I know utilities like this can evoke lots of opinions :) so appreciate hearing if you'd find any of these useful and ways to make it better (or if any of these seem to have better alternatives).

What it does: It is nothing more than a tiny (\~1000 loc) library of \~30 string, file, and object utilities.

In particular, I find I routinely want atomic output files (possibly with backups), atomic variables, and a few other things like base36 and timestamped random identifiers. You can just re-type these snippets each time, but I've found this lib has saved me a lot of copy/paste over time.

Target audience: Programmers using file operations, identifiers, or simple string manipulations.

Comparison to other tools: These are all fairly small tools, so the normal alternative is to just use Python standard libraries directly. Whether to do this is subjective but I find it handy to `uv add strif` and know it saves typing.

boltons is a much larger library of general utilities. I'm sure a lot of it

Using Django+Sqlite in production

I've been researching the use of Sqlite in production and came across this thread which has some resources, mainly about the benefits and also how to performance tune Sqlite.

My intent right now is to keep my app on Sqlite. The application is a B2B app with limited number of users, and it is not write heavy (a few hundred writes per day). It also simplifies my tech stack.

I'd like to check if someone has resources specific on how to deploy and run a Django+Sqlite app.

Over in the Ruby on Rails world, I saw a movement to help developers achieve this, and was wondering if there is something equivalent in the Django.

Cogitator - A Python Toolkit for Chain-of-Thought Prompting

GitHub Link: [https://github.com/habedi/cogitator](https://github.com/habedi/cogitator)

**What my project does**

Cogitator is a Python library/toolkit that makes it easier to experiment with and use various chain-of-thought (CoT) prompting methods for large language models (LLMs). CoT prompting is a family of techniques that helps LLMs improve their reasoning and performance on complex tasks (like question-answering, math, and problem-solving) by guiding them to generate intermediate steps before giving a final answer.

Cogitator currently provides:

* Support for OpenAI and Ollama as LLM backends.
* Implementations for popular CoT strategies such as Self-Consistency, Tree of Thoughts (ToT), Graph of Thoughts (GoT), Automatic CoT (Auto-CoT), Least-to-Most Prompting, and Clustered Distance-Weighted CoT.
* A unified sync/async API for interacting with these strategies.
* Support for structured model outputs using Pydantic.
* A basic benchmarking framework.

The project is in beta stage. The README in the GitHub repository has more details, installation instructions, and examples.

**Target audience**

* AI/ML researchers looking to experiment with or benchmark different CoT techniques.
* Python developers who want to integrate more advanced reasoning capabilities into their LLM-powered applications.

In general, CoT could be useful if you're working on tasks that need multi-step reasoning or want to improve the reliability of LLM outputs for more complicated queries.

**Why I made this**

I started developing Cogitator because I found that

Looking for help regarding a flask project (I want to input question (with both text and equations) , save it in MySQL and print in both word doc and pdf)

I am working on a basic question paper generator where users can enter questions for each subject, and the the questions are saved in MySQL. The admin can generate question papers in form of both pdf and word. I am unable to find a way to let users to add questions that has equations or formulas. I tried using tinymce and mathjack but it doesn't seem to support all formats (like the bigger fractions). I also tried rendering latex to text or image and is too complicated for me to understand how to make it work properly.

I built my own asyncio to understand how async I/O works under the hood

Hey everyone!

I've always been a bit frustrated by my lack of understanding of how blocking I/O actions are actually processed under the hood when using async in Python.

So I decided to try to build my own version of asyncio to see if I could come up with something that actually works. Trying to solve the problem myself often helps me a lot when I'm trying to grok how something works.

I had a lot of fun doing it and felt it might benefit others, so I ended up writing a blog post.

Anyway, here it is. Hope it can help someone else!
