Multiple Long Running task > 500 seconds stuck in STARTED state

I am building a celery (remote workers) + flask application(using send_task). The issue I am facing is that when I send multiple tasks to the celery worker, the tasks are executed (2 API calls are successful both return 200, one takes less than 60 seconds and the other takes greater than 400 seconds) but the task status is stuck in STARTED state. I have tried to increase the timeout for the API, added the soft_time_limit and time_limit, but whenever I add more task the task start they execute but the state is stuck. If I only send one task then it executes correctly and the status is also updated correctly. I am just not able to figure out the problem.

Planning a project and getting things “connected”

I think I know the basics of Django but when I comes to connecting the pieces of a project together. For someone with little to no experience, what are ways to learn?

Example. For my work I was thinking of building a “hotel/barracks rooms” management system. Kind of similar to a hotel. Issues; some rooms share a bathroom, some rooms have to be female only since they share a bathroom, if a female is assigned to the room block any male from being assigned. The majority of rooms are male BUT some male rooms will need to be converted if there’s more females than males during that period. I would need a check in and “check out date” we don’t know when they checkout as it depends on them getting in-processed into the installation.

For someone with experience this might seem easy, for someone learning planning a project is difficult. What are some ways to fix this?

How to enable zsh terminal in jupyter when launching from conda environment

So basically I want the terminal that is launched within jupyter (specifically jupyter-lab) to be zsh instead of bash.
If I am have not expressed the my querry clearly attached screenshots might help.
ss-1: default zsh shell with 'ml0' conda env
ss-2 : terminal launched from jupyter-lab uses bash by default and also loses the conda env
And my major motive is to preserve the conda environment in the jupyter from which it is launched.

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)

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 noscript, 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.

Comparison

There was a site a while ago that I believe did the same thing,

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

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.

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

If I chose nodejs or something else I wouldnt build a service for living in that short period of time..
