Live server set-up for developing with Flask?

I'm new to programming (few months in, learning in my spare time) and I've started to learn Flask to develop web apps with Python.

I'm using VSCode mostly and what I really need is for a live server type of setup so I can see the changes I'm making in HTML/CSS, as I make them. The difficulty I'm facing is that the live server plugins I've tried in VSCode don't show the results properly. E.g. they will display {{ myflaskvariable }} rather than the actual variable - which obviously makes things harder than I feel they need to be!

Everything displays fine using 'flask run' from the terminal, but I can't seem to get a live server to work the same way. Any suggestions?

D Efficient CNNs for inference

I am working on an object detection project using high resolution images.

Are there any techniques that can make a trained CNN (UNet) efficient during inference? I know pruning is one such technique, but it risks loss of accuracy and parallelizability.

What do you do when you are frustrated?

Hi everyone!

I know this post deviates a bit from what people usually post here, but I thought it would be interesting to hear what those of you who are already developers or have code longer do with this.

How do you deal with the frustration? I'm in the phase where I haven't fully understood yet that writing code and making it actually work properly takes time, so I can get frustrated when I've been sitting for a little while and haven't found a solution yet.

Of course, what I'm doing now is just stepping away from the PC for a while and thinking about something else, but want to hear what other tips you have.

Thank you!

temporals - A time, date and datetime periods support

Hi guys!


I'm excited (and mostly nervous) to share my first Python project that is aimed at the wider audience of Python users.


# What Does It Do


temporals aims to provide a minimalistic utility layer on top of the Python standard library's datetime package in regards to working with time, date and datetime periods.


The library offers three different flavours of periods:

`TimePeriod`
DatePeriod
`DatetimePeriod`


As you can probably guess from the names, each period corresponds to a `datetime`object and contains the same as its start and end variables.


When working with periods, each and every one of them is viewed as existing on a timeline, thus each period contains its own implementation of methods related to that position in time:


Methods like is_before, is_after and get_interim serve the purpose of comparison between periods that exist in time in a non-overlapping fashion;
Methods like `overlapped_by`, `overlaps_with`, `get_overlap` and `get_disconnect` provide the ability to work with periods that exist in time in an overlapping fashion;
Operations such as equality between periods and the in keyword allow you to determine if a period is equal to, or exists fully within, another period


Additionally, each period instance contains a Duration under its duration attribute which is built on top

Asynchronous framework for working with RabbitMQ

Hello everybody! I wrote the first version of a small (so far) framework that allows you to work with the RabbitMQ broker.

I hope that this small project can benefit people and grow into something more. The main idea is to process essays asynchronously without resorting to extending the code ring in the project. Among the nice bonuses: there is validation of field types from messages (something like what is in FastAPI, only without dependency injection).

I would like you to study my code and, if anyone has any criticism or recommendations, leave your feedback. Thank you very much!

Issues with flask, uwsgi, nginx, and websockets.

I have an existing application (resume website) that is being served just fine with flask/python/uwsgi/nginx, the problem was when I tried to introduce websockets. I have read the documentation for flask socket.io in terms of deployment, not even sure if I need it, honestly I have no idea what the h3ll I am doing with the sockets. It seems like there is gevent, websocket native uwsgi, socket.io, and probably a myriad of others.

I essentially wrote a chat server backend in golang that uses rabbitmq, and i then wrote a test python script that sends messages over websockets using asyncio and websockets, this works fine.

The thought behind the project was to have an administration page be served by flask that allows the admin to see all rabbitmq queues, choose a queue, read messages from queue, and respond to queue. I could achieve this through polling directly to the backend, but I wanted to securely incoporate websockets to handle this in a secure asynchronous way being served by flask/python.

Then implement a chat modal on my resume page that allows anonymous users, to initiate chats, creating a rabbitmq queue unique to that user based on session id, admin receives new queues and messages,

Can I migrate my website from WordPress to a coded platform like Django

Five months ago, I posted a similar question on the WordPress subreddit, but it didn’t gain much traction, and the feedback was mostly negative, tbh.

My original post was along these lines:

"I'm currently trying to launch an e-commerce site using WordPress with a theme builder. I really believe this business idea can succeed in the near future (God willing). This might sound odd, but I feel uneasy about WordPress, even though I’ve never written a single line of code. To add to that, I’m not comfortable using Dokan (the marketplace plugin) either, as I want to create a highly customized multi-vendor marketplace."

Fast forward a few months, and I've returned to working on my website. I’m not as uncomfortable with WordPress anymore, and I’ve completed the entire site design—it looks great! But now, I’m aiming Big. I want to grow this into a fully-fledged platform with apps for buyers, sellers, and delivery. I’m considering finding a technical co-founder to build this vision from scratch. The challenge? My budget is tight (hence, WordPress initially).

Any advice on how to proceed or whether I should stick with WordPress? Should I really be looking for a co-founder at this stage?

Configuring a Lambda to act as a Celery Worker.

Hi, i'm looking for advise on how to proper use a lambda to mimic a worker job, by using the following configuration:

AWS MQ using rabbitMQ as broker.

Lambda with configured Trigger listening on a MQ queue.

A Workflow defined in my celery app with some tasks:

task\_01: runs on a celery worker instance.
task\_02: runs on lambda, i put then on a specific queue that no other worker listen to.
task\_03: runs on a celery worker instance.

    workflow = chain(
        task_01.s(),
        task_02.s(),
        task_03.s()
)

If i execute task\_01, the lambda on task\_02 is triggered correctly, but i need to mimic celery code, save the result to the backend and trigger task\_03 correctly.

I'm currently using the code below to save the task\_02 result, but i need to make some workflow functions like chain, group, chord, to be called.

from celery.worker.request import Request

def handler(event, context):

Having hard time implementing search functionality in django

I'm a complete beginner in backend development and I'm currently working on a search functionality that includes multiple advanced filters. I'm using Django Filters for filtering, but since I'm new to this, I haven't found many tutorials on YouTube. Most of the content I came across relates to Q objects, which raises the question of which is better to use: Django Filters or Q objects?

Additionally, I'm gathering data from APIs for weather, air quality, and datasets related to the cost of living. I'm unsure how to store this data so that when users apply filters in their searches, the system can display relevant cities. The project is aimed at digital nomads looking for cities based on specific criteria.

I would greatly apprciate any guidance on these topics, and I apologize if my questions seem basic.

A search engine for all your memes - written in Python.

The app is open source and written entirely in Python 👉 https://github.com/neonwatty/meme\_search

# What My Project Does

The open source engine indexes your memes by their visual content and text, making them easily searchable. Drag and drop recovered memes into any messager.

The backend is built using these great open source components:

moondream: a tiny, kickass vision language model
all-MiniLM-L6-v2: a popular text embedding model
faiss: a fast and efficient vector db
sqlite: the swiss army knife of dbs

# Target Audience

This is a toy project. Open source and made for fun.

# Comparison

immich: great open source image organizer, does not (yet) have powerful image-to-text indexing
other local photo apps: some allow for indexing but not quite at the level of a vlm yet

Guidance on deployment

Hi guys!!
So, I have a flask application that I want to deploy over the internet for data transmission between a webhook application and a computer doing a bunch of scientific calculations.

The idea is to deploy this app to be visible over the internet, so I can send post request (from the webhook) to the flask application, the flask application request the calculation from the machine, and send it back.

So, I'm wondering if I need some special configuration to protect the network or it should be fine just with flask. (Note such service will not be available for anyone but the backend function with the IP address and port of the machine that request the calculations).

Also, the machine running the post get request should the same one as the one running the scientific calculations or in the same local network.

Can anyone point out the risk of such idea (vulnerability on the system) or any other recommendations?
