Kanban-Tui, Moving Cards around in the Terminal
* **What My Project Does**
Kanban-Tui is a CLI application to manage tasks and (hopefully) makes you more productive.
It is quite customizable and my motivation was to have a better experience using the fantastic [textual](https://textual.textualize.io) package than with my
previous project [kanban-python](https://github.com/Zaloog/kanban-python) which just utilizes `rich`. It was also the first project, where I used `uv` and I wanted to get more comfortable with databases (sqlite).
With v0.2.0 I also included a `Demo Mode` to create a temporary database and config to play around and test things out.
You can find it on PyPi: [Link](https://pypi.org/project/kanban-tui/)
Source Code on github: [Link](https://github.com/Zaloog/kanban-tui)
* **Target Audience** (e.g., Is it meant for production, just a toy project, etc.)
For everyone who likes to work in the terminal and does not want to miss a more graphical Interface. It is ready to use, but I plan to add multiple boards feature after vacation. That might lead to a db schema change, so keep that in mind, when playing around.
* **Comparison** (A brief comparison explaining how it differs from existing alternatives.)
Its similar to kanban-python, but has not yet all the features.
Also with the TUI I was able to utilize vim-like motions to move cards around, which comes closer to the feeling of actually moving

Pre-commit hooks that autogenerate iPython notebook diffs
What My Project Does
Nowadays, I use iPython notebooks a lot in my software development nowadays. It's a nice way to debug things without having to fire up pdb; I'll often use it when I'm trying to debug and explore a new API.
Unfortunately, notebooks are really hard to diff in Git. I use magit and git diffs pretty extensively when I change code, and I rely heavily them to make sure I haven't introduced typos or bugs. iPython notebooks are just JSON blobs, though, so git gives me a horrible, incoherent mess. I basically commit them blindly without checking the code at all nowadays, which isn't ideal.
So to resolve this I generate a readable version of the notebook, and check the diff for that. Specifically, I wrote a script that extracts only the Python code from the iPython notebook (which is essentially a JSON file). Then, whenever I commit a change to the iPython notebook, it:
1. Automatically generates the Python-only version alongside the original notebook.
2. Commits both files to the repository.
To make sure it runs when I need it, I created a git pre-commit hook. Git's default pre-commit hooks are a little difficult to use, so I built a hook for

Finally I make money from my django project
It was quite long journey.. it took about a year and a half to build and no sales for 4months.. I was quite depressed..
I figured out what to fix and my site started to make sales and now I make $100~$200 in revenue everyday. It is not that big amount but I can do this for living and I know how to scale up
I feel really thanks to django foundation..
If I chose nodejs or something else I wouldnt build a service for living in that short period of time..

Speeding up PyTest by removing big libraries
I've been working on a small project that uses "big" libraries, and it was extremely annoying to have `pytest` to take 15–20 seconds to run 6 test cases that were not even doing anything.
Armed with the excellent [PyInstrument](https://www.reddit.com/r/Python/comments/1g1az6i/pyinstrument_v50_flamegraphs_for_python/) I went ahead to search for what was the reason.
Turns out that biggish libraries are taking a lot of time to load, maybe because of the `importlib` method used by my `pytest`, or whatever.
But I don't really need these libraries in the tests … so how about I remove them?
# tests/conftest.py
import sys
from unittest.mock import MagicMock
def pytest_sessionstart():
sys.modules['networkx'] = MagicMock()
sys.modules['transformers'] = MagicMock()
And yes, this worked wonders! Reduced the tests run from 15 to much lower than 1 second from `pytest` start to results finish.
I would have loved to remove `sqlalchemy` as well, but unfortunately `sqlmodel` is coupled with it so much it is inseparable from the models based on `SQLModel`.
Would love to hear your reaction to this kind of heresy.

Old school 2000s mouse accessory: Particles following your mouse! Get color under cursor! And more!
I would have loved to instead call this thread: "You can now have shit stuck to your mouse", but I felt it wouldn't take very long until it was removed.
# What my project does:
I've had an idea somewhere in 2022: I want rainbow trails for my mouse cursor. Available software was naught. So I made it myself!
- It can draw particles of any number and color spawning from your mouse cursor. With multiple vectors, influences from mouse motion and rotation, many ideas can be realized: Crazy or decent, river or beehive, smoke or explosion.
- or it can be the time
- Get RGB or RGB complementary color
- or get RYB and RYB complementary color from under it.
- Also useless stuff like the time with milliseconds, system cpu and ram usage, individual or at the same time, if you need it visible there for some obscure reason.
- An image is also possible - default is the poop emoji, of course.
(Just got a new idea: get color from under cursor and spawn particle with it for a sort of "scraping off pixels" effect)

Tips for Command Line Project
Hello! I'm making a short project to have a little experience creating a command line tool, as well as getting a project onto PyPI. Mainly, I'm doing this because I think it's cool, and it would be awesome if a friend could pip3 install my project and just have a CLI tool off the install, similar to how the `qrcode` Python library comes with the `qr` CLI tool when installed. If you have any tips **AT ALL** for anything you see, like project organization, overall Python usage, or too many commits (is that possible), please tell me, I'm a sponge for info!
I'm still making the GUI portion, but the actual command line part should be done!
Off a google search, I understand there is already a PyPI project [Jonathan Löfgren\](https://github.com/jonathanlofgren/running/blob/master/.gitignore) made some time ago for converting paces into different distance paces. The purpose of my project here is to get a little experience creating a CLI tool I could use along with the overall process of getting something onto PyPI that works. If what I'm doing is majorly wrong, however, please tell me, I don't know!

Qtcord - A lightweight, native Discord client for Windows and Linux
Ever noticed that the normal Discord client is bloated and takes too long to load for quick conversations? Well, here's the solution. Qtcord is a very lightweight Discord client written by the open source community and me.
Shoutout to randomusername-a for optimizing the backend and improving the UI of this project!
# How Qtcord works.
Qtcord uses Python Requests to send and retrieve data from the Discord API.
I reverse engineered some of the requests with the browser devtools network tab. The rest were implemented from documentation/tutorials that various people wrote online, including the actual Discord API docs!
For the GUI, I chose PySide6 because it is very easy to use, especially with Qt Designer. This saved me time hardcoding the UI.
# Target Audience
Qtcord is designed for people who don't need the extra features and ads from Discord.
# Why is Qtcord different?
Qtcord is different because it is native. For example, the normal Discord client takes around 500 MiB of RAM. Qtcord only takes 138 MiB of RAM.
# Downloads and Source
You can get builds of Qtcord here.
Please give my source code repository for Qtcord a star if it's interesting! 🌟

Teaching the world's largest programming lesson
This past Saturday I taught the world's largest programming lesson, with 1668 students, breaking the previous record of 724 students.
We broke the record in Portugal 🇵🇹 and the event was co-organised by a local university and a company I used to work at.
It was an insane event.
I have been in plenty of events with WAY more than 2k people.
Music festivals, sports matches, etc.
And yet, nothing beat being on stage, teaching Python to ~1750 students.
(The official record is at 1668 because some students were disqualified for not actually following the lesson 🤦.)
The lesson was split in three and I taught the middle segment, which was scheduled to last for half of the lesson.
The professor before me taught the students what an algorithm was, conceptually.
One of the examples provided was a brute forcy algorithm to solve a Sudoku puzzle.
Then, I taught them some basic Python syntax.
The objective was for me to introduce enough syntax so that we could implement the algorithm described in the first part on top of an abstraction that I created beforehand.
Finally, a third professor showed a couple of more advanced applications of Python, like creating a RAG application to interact with a major literary work that Portuguese students

I made a website for finding deals on Pokemon cards on Ebay
Site: https://www.jimmyrustles.com/pokemondeals
Github: https://www.github.com/sgriffin53/pokemontcgdealfinderapp
What My Project Does
For the past few weeks I've been working on a Pokemon deal finder website. It works by finding listings from Ebay and card valuations from Pricecharting then returns the listings with the biggest difference in card price compared to card valuation.
It searches Ebay for 112 different sets and right now it has around 200,000 listings.
The listings will be updated every 8 hours.
It seems pretty successful at identifying cards. Most of the misidentification seems to be when a seller has mislabelled the card or set in the title, but for the most part, it seems good at identifying the cards.
It seems to find deals well, though a lot of the deals are heavily played cards that are underpriced due to their condition. For example, on the front page, there's a heavily played Umbreon EX #112 from Unseen Forces that's valued at $165.60 and the price is $19.96.
Target Audience
There's a large market for people buying and selling cards on Ebay. Users are constantly looking for good deals, and this tool is a way to automate looking for deals by comparing listing prices to valuations.
