Old parameters being processed

In my app I have an HTML table showing values on one of my Flask app pages. The values are being stored in a simple list: prediction_list=[]

I want to be able to clear the table, but it seems very inconsistent; sometimes it will clear the values on the page, other times nothing happens, even though the list object is showing as empty in my logging/console output.

Possibly it's a caching thing in the browser, but is there anything I'm doing wrong here?

@app.route('/predictions/',methods=('GET', 'POST'))
def predictions():
if request.method == 'POST':
# This bit seems to work fine... calls a "predict" function and adds a row to the predictions table
if request.form'action' == 'predict':
home = request.form'home'
away = request.form'away'

[P] Updates on OpenCL backend for Pytorch

I develop [the OpenCL backend for pytorch](https://github.com/artyom-beilis/pytorch_dlprim) - it allows to train your networks on AMD, NVidia and Intel GPUs on both Windows and Linux. Unlike cuda/cudnn based solution - it is cross platform and fully open source.

Updates:

1. With an assistance from pytorch core developers now pytorch 2.4 is supported
2. Now it is easy to install it - I provide now prebuild packages for Linux and Windows - just install whl package and you are good to go
3. Lots of other improvements

How do you use it:

- Download whl file from project page according to operating system, python version and pytorch version
- Install CPU version of pytorch and install whl you downloaded, for example `pytorch_ocl-0.1.0+torch2.4-cp310-none-linux_x86_64.whl`
- Now just `import pytorch_ocl` and now you can train on OpenCL `ocl` devices: `torch.randn(10,10,dev='ocl:2')

How is the performance: while it isn't as good as native NVidia cuda or AMD rocm it still gives [reasonable performance](https://github.com/artyom-beilis/pytorch_dlprim/blob/master/benchmark.md) depending on platform, network - usually around 60-70% for training and 70-80% for inference.

Pythonanywhere —> Azure?

I am testing a flask api, that’s exposed to the internet, on pythonanywhere.

If I need to move it to something that’s on “azure” (for enterprise reasons), may I ask what’s the right service, and that’s hopefully low cost, to use on Azure? Thank you!

Posting user uploads to Cloudflare Images

I'm working on an app, and (for the first time ever) I'm allowing users to upload image files to Cloudflare Images.

Is the best (and safest) option to:

1. add a file input on the front end (inside a form),
2. submit the form,
3. save the file locally in a temp folder,
4. post the file to Cloudflare Images with a Celery task,
5. and then delete the local file?

Is there a safe and secure way to do it from the front-end instead of having to do all the file saving/deleting on every request?

I've been working as a Django developer for a year, and I'm considering applying for a new position elsewhere. However, I'm not sure if there are any specific things I should learn or know by now. What skills and knowledge should I have at this point, and what kind of interview questions can I expect with my level of experience?

How do I make my application interactive while being able to bundle my JavaScript

So far my Django app was just basic CRUD but now my front end displays a form and the form has a table. With a button I can delete rows and add rows. This might sound simple but I’m horribly lost. I want to use the JavaScript to populate the form, even when the template is populated by Django. But now how to I pass values from Django to the front end so my JavaScript can use it. Do I have to check if a variable is set in local storage or something?

Hype About .NET

Microsoft puts in their landing page that .NET-based web servers can handle 7 million requests making it the fastest web server out there. What is your opinion on this? Personally, I'm attracted towards it, however the development experience is pure shit compared to Python (not talking about writing actual program, but about setting up environments, hot reloading, memory consumption etc.).


Why Django is underperforming except for the reason that Python is an interpreted language? Can me make it match the speed of .NET?



PS: Django is the best framework out there that provides the right balance between abstraction and ease-of-use and its my most favorite framework.

I made a Spotify Genre Tracker with the goal of broadening my music taste.

# What My Project Does


Recently I've noticed that I spend way too much time listening to the same playlists/genres over and over again so with the goal of expanding my music knowledge I've decided to make this program that keeps track of the listening time for all the genres in Spotify.

It works by having two threads, one for the cli and user input and another that constantly pings the Spotify API for the currently playing song and keeps track of the listening time in an sqlite database.


# Target Audience

This project is meant for anyone that has a hard time finding new music genres to listen to. It is by no means production ready but if I see people enjoy it I might setup a website for it and make it public.


# Comparison

As far as I'm aware there aren't any projects like this one. The one's available out there keep track of all your stats but none give you a set goal or have the option to track the listening time for a given genre.

Any comments/recommendations are welcome. Hope it helps someone learn more about music!

Here's the repo for anyone that wants to check it

Local to Live Question

I'm considering starting a bigger project than I'm used to. I've flipped through a lot of tutorials but haven't found a solid answer to a question I have.

Most of my projects have just been php and sql based. I just have the files on a webhost and it's live.

Can I do that with Django? It seems like a way different process to go live with Django. I was considering starting with a Django boilerplate.

I Created the Definitive AUTOMATIC Shiny Hunter for Pokémon BDSP in Python

What My Project Does: Hey everyone! I am Dinones! I coded a Python program using object detection that lets my computer hunt for shiny Pokémon on my physical Nintendo Switch while I sleep. So far, I’ve automatically caught shiny Pokémon like Giratina, Dialga or Azelf, Rotom, Drifloon, all three starters, and more in Pokémon BDSP. Curious to see how it works? Check it out! The program is available for everyone! Obviously, for free; I'm just a student who likes to program this stuff in his free time :)

The games run on a Nintendo Switch (not emulated, a real one). The program gets the output images using a capture card, then, it process them to detect whether the pokemon is shiny or not (OpenCV). Finally, it emulates the joycons using bluetooth (NXBT) and control the Nintendo.

I also want to know what do you think about it: Is it fair to use it in singleplayer? And multiplayer?

Target Audience: All Pokémon BDSP gamers.
Comparison: As far as I know, nobody did this before.
