Developing flask backend

Hey guys, hope y'all are doing well.
I'm developing a flask backend to run a segformer and an stable diffusion model. I got both of them off of hugging face. I tested everything out in Jupiter and they work fine.
My tech stack is currently a next/reactjs frontend, SupaBase for auth etc, stripe for payments and flask as an API to provide the key functionality of the AI.
I'm getting started with the flask backend, and although I've used it in the past, this is the first time I'm using it for a production backend. So, logically, my questions are:

-Do I need to do something for multi threading so that it can support multiple users' requests at the same time?

-Do I need to add something for token verification etc.

-Which remote server service provides good GPUs for the segformer and stable diffusion to run properly?

-Any other key things to look out for to avoid rookie mistakes would be greatly appreciated.

I already installed waitress for the deployment etc and I was wondering whether I should dockerize it too after it's developed.

Table goes blank when page is refreshed...

shows is a list of lists being passed to the HTML file used to populate a table. When I run the program and open the page for the first time, the table populates just like it's supposed to. But if I refresh the page in the browser, the table goes blank except for the headers. Why is this happening?

from flask import Flask, rendertemplate
from getshows import getshows
import pandas as pd
from time import sleep


filename = "Output.csv"
df = pd.readcsv("ListedVenues.csv")
# create an empty dictionary to hold the show information
showstonight = {
"venue": ,
"show": ,
"date": ,
}
# make the API calls to get show information and store it in the showstonight dictionary
for index, row in df.iterrows():
venue, bands, date = getshows(row"Venue

Something really really weird happens...

So my base template is (deleted link to the CSS spreadsheet due to debugging):

https://preview.redd.it/mwpy7k4r29md1.png?width=422&format=png&auto=webp&s=3adfe342a4ff8fc77b3c3eb71ffcc08950e67224

\^ And then I have this template with internal CSS. And when I extend it (pic 2), it doesn't render at all. When I write a text to these divs, they only expand to the point to accomodate that text.


But when I'm not extending it (3), then it renders fine, like it's supposed to render.

Anyone?

Looking to Collaborate on Django Projects or Start Something New

Hey everyone!

I’ve completed a few Django projects, including a library system, blog platform, and a face and plate recognition attendance app using RabbitMQ. I’m experienced with Django, Celery, RabbitMQ, and both relational and non-relational databases.

I’m looking to collaborate on new projects to strengthen my GitHub portfolio. If you have any project ideas, need an extra hand on existing projects, or want to brainstorm something cool, let’s connect!

Can anyone help me complete my tracker server (BitTorrent Protocol)

I am trying to create my own private bittorrent protocol which I will use for load balancing static data in the web server to visitors. I have app.py written, among other things, but what is weird to me is that I can initiate the magnet url download process, but then no data is transferred. Additionally, I am able to download .torrent files.


This is the repository, could someone take a look at it and tell me what they think? I'm planning to make this a free and public web forum.

Smartcut: Super fast cutting and trimming of videos

What My Project Does

Smartcut is to my knowledge the most robust open-source implementation of frame accurate video cutting without recoding, a.k.a smart cut, smart encoding, smart render, etc.

It uses PyAV and libavcodec (ffmpeg internals) to encode a small part of the video near the cutpoints and then uses libavformat to stitch the recoded segments and parts of the original video back together into a whole video.

https://github.com/skeskinen/smartcut

Target Audience

This project is for people who want to cut videos really fast from the command line. This could be useful e.g. as part of a script that goes through a directory and quickly cuts off some part of the videos. It could also be used as a part of a video editor project, like I've done in my GUI video editor project.

It is also one of the largest available projects that uses PyAV (the pythonic bindings for libav project) and really showcases the awesomeness of the library. I also contributed 4 patches to PyAV and the maintainer was really cool to work with.

Comparison

The github page has a pretty nice list of related projects: https://github.com/skeskinen/smartcut?tab=readme-ov-file#other-projects

The most obvious comparison is to lossless-cut which is a popular open-source video editor written in TypeScript and Electron

Is Django Still Relevant for Backend Jobs?

Hi Djangonauts!

I'm a junior CS student with some experience in Django (intermediate functionality, needs frontend work). While I enjoy using Django, I'm concerned about landing a job with it after graduation. Many postings seem to focus on C# and .NET

My questions are:

Is Django still a valuable skill to learn for backend development positions?
Would focusing on C# and .NET offer better job prospects, considering the current market?

My dilemma:

I'm unsure if I should continue building my Django skills or switch gears to C# and .NET for better job security.

I'm feeling some pressure to upskill and avoid the pitfalls of job seekers lacking the right skills.
so I'm trying hard and pushing through burnouts, trying to upskill in order to strengthen my capability and candidacy.

Why not just get your plots in numpy?!

Seriously, that's the question!

Why not just have simple
plot1(values,size,title, scatter=True, pt_color, ...)->np.ndarray
function API that gives you your plot (parts like figure and grid, axis, labels, etc) as numpy arrays for you to overlay, mask, render, stretch, transform, etc how you need with your usual basic array/tensor operations at whatever location of the frame/canvas/memory you need?

Sample implementation: https://github.com/bedbad/justpyplot

# What my project does?

Just implements the function above

When I render it, it already beats matplotlib and not by a small margin and it's not the ideal yet:

Plotting itself done in vectorized approach and can be done right utilising the GPUs fully

plot1, plot2 .. plotN is just dependency dimensionality you're plotting (1D values, 2D, add more can add more if wanted)

Target Audience? What it Compares against?
Whoever needs real-time or composable or standalone plotting library or generally use and don't like performance of matplotlib [1, 2, 3\]

I use something similar thing based on that for all of my work plotting needs and proved to be useful in robotics where you have a physical feedback loop based on the dependency you're plotting when you manipulating it by hand such as steering the drone;

Anyone made the switch from ASP.NET Core?

I'm a .NET developer by daytrade, and I'm starting side projects from time to time. Usually it's been Node.js/Go/ASP.NET, but I've never done Django yet. I'm just not a big Python user in general.

However, it now looks like I have to build an admin panel by myself for a side project I've just started, and Django entered my mind as it's got one by default. It looks like Django + DRF is sort of a ASP.NET/Spring lite-edition, so I'm looking to see some feedback if anyone has actually moved from ASP.NET to Django, or just used both and have some feedback to share.

One thing I'm kind of suspicious about is the performance. ASP.NET is what, 10x faster than Django? However I know it probably won't make a real difference, but seems a shame if there is no real benefit to using Django.

Web scraping with GPT-4o: powerful but expensive

Hey folks,

So I've been messing around with OpenAI's new structured outputs feature and decided to build an AI-powered web scraper. Thought I'd share some of the cool (and not so cool) stuff I found.

**The Good:**

* This thing can parse some pretty complex tables. I threw a 10-day weather forecast at it with all sorts of nested data, and it handled it like well.
* It's smart enough to figure out merged cells and hidden data in the HTML.

**The Bad:**

* Wikipedia tables with combined rows? Yeah, that broke it.
* Asking it to give XPaths directly was a mess. Had to do some workarounds.

**The Ugly:**

* GPT-4o is expensive! Spent $24 in two days just messing around.

I made a quick demo with Streamlit if anyone wants to check it out: [https://orange-resonance-9766.ploomberapp.io](https://orange-resonance-9766.ploomberapp.io)

Deploying on Choreo.dev?

Hi Guys,

I am testing out different options for hosting my django + postgresql + react application. I found https://choreo.dev/ very convenient because i can manage all parts of the application on one dashboard instead of using 3 different providers.

However, it makes me a little suspicious that you can hardly find anything about choreo on the internet + the documentation is also not that extensive.

Do any of you have experience with the provider, and if so, what do you think?
