FastStream: a powerful and easy-to-use library for building services with event streams

**FastStream** (https://github.com/airtai/faststream) simplifies the process of writing producers and consumers for message queues, handling all the parsing, networking and documentation generation automatically. It is a new package based on the ideas and experiences gained from **FastKafka** and **Propan**. By joining our forces, we picked up the best from both packages and created a unified way to write services capable of processing streamed data regardless of the underlying protocol. We'll continue to maintain both packages, but new development will be in this project.

Making streaming microservices has never been easier. Designed with junior developers in mind, **FastStream** simplifies your work while keeping the door open for more advanced use cases. Here's a look at the core features that make **FastStream** a go-to framework for modern, data-centric microservices.

Multiple Brokers: FastStream provides a unified API to work across multiple message brokers ([Apache Kafka](https://kafka.apache.org/), [RabbitMQ](https://www.rabbitmq.com/), [NATS](https://nats.io/) and [Redis](https://redis.io/))
**Pydantic Validation**: Leverage **Pydantic's** validation capabilities to serialize and validate incoming messages
[Automatic Docs](https://faststream.airt.ai/latest/getting-started/asyncapi/export/): Stay ahead with automatic [AsyncAPI](https://www.asyncapi.com/) documentation
Intuitive: Full-typed editor support makes your development experience smooth, catching errors before they reach runtime
[Powerful Dependency Injection System](https://faststream.airt.ai/latest/getting-started/dependencies/): Manage your service dependencies efficiently with FastStream's built-in DI system
**Testable**: Supports in-memory tests, making your CI/CD

Simple GUI directory contents extraction for chatbot submission

* **What My Project Does :**

A simple GUI tool that extracts a given directory structure and the contents of all its files then prints everything in an organized textbox + in an optional .txt file.

I made it to lazily submit entire projects to ChatGPT and let it "understand" their structure quickly.

* **Target Audience**

Anyone using chatgpt (or any llm chatbot) for writing or debugging code

* **Comparison**

There are probably better lightweight alternatives that I don't know about but this might be an easy to use alternative

Is it worth it to take Coursera course?

Did someone take the course
Programming for Everybody (Getting Started with Python) by University of Michigan?
Or what sources would you recommend for someone who doesn't particularly like Python however understands it's necessary to learn it? There are also some courses on Udemy, but I personally like Coursera better

Thanks!

D How do you structure your codebase and workflow for a new research project?

Suppose you have got a new idea about a solution to a problem in the domain you are working in. How do you go about implementing the thing from the ground up?

What is the general structure of the codebase you construct for your project?

How do you go about iteratively training and testing your solution until you arrive at a final solution where you can write a paper for publication?


Is there any design recipe you follow? Where did you learn it from?

Deployed Django with Redis and Celery to AWS ECS using GithubAction

https://preview.redd.it/ty6v9fzurtxd1.png?width=1553&format=png&auto=webp&s=0e379df06d1d95edbcda627e40ac7b41913f8e5b

# ### AWS Deployment Steps

The deployment uses AWS ECS, Terraform, and GitHub Actions for CI/CD:

1. AWS Resources Setup:
An ECS Cluster is created using Terraform.
The Django, Celery worker, and Redis containers are deployed using ECS tasks.
A CloudWatch Log Group is configured to capture logs from the containers.
Network resources like VPC, subnets, security groups, and an Internet Gateway are created using Terraform.
2. GitHub Actions CI/CD:
The GitHub Actions workflow handles the build and deployment process.
Docker images are built and pushed to Amazon ECR.
Terraform manages the infrastructure as code for consistent deployments.
The public IP of the ECS service is retrieved and used to update Django's ALLOWED_HOSTS.

\-------------------------------------------------------------------------------------------

Set Up of All AWS Infra

the 4 files inside terrform working together

Redis and Django application are two separated container

And finally below is the digram for the entire deployement HLD, from github action to running as a Task in ECS

Best gui for local client app?

I'm writing an application which is local. No server. I'm using python and I'm wanting to know people's opinions on the best gui to use.

So far I've used tkinter but it feels clunky and heavy, like it's from the early 2000s.

Can anyone recommend something better for modern looking stuff? Maybe I'm using tkinter wrong?

Any advice would be appreciated.

Improve TTFB

Hello,

I’m running into a response time issue with a Flask server in a test setup, and I’m hoping someone might have insights on how to tackle it. The server is set up to handle a pretty large data retrieval task—about 110MB, consisting of around 15,000 rows of complex JSON objects. Flask seems to handle the retrieval and processing reasonably well; it takes about 3 seconds to generate the JSON response. So far, so good.

The problem arises after the data is ready to be sent. I’m seeing a significant delay—around 6 additional seconds—between the endpoint finishing and the start of the response download. This delay feels unusually long, especially given the relatively quick processing time of the data retrieval itself. To troubleshoot, I measured the times directly in the endpoint method and looked at the Time to First Byte (TTFB) using Postman, which confirmed this lag.

I also tried enabling GZIP compression through Flask-Compress, hoping that reducing the response size might help speed things up. However, this didn’t have any effect; the response size stayed roughly the same, and the transmission time didn’t improve.

At this point, I’m not sure what else to try to minimize that 6-second delay. Does anyone have suggestions

D I’m an ML/programming educator - I was invited as ceo of codesmith to Berlin Global Dialogue (tech/AI insider conference) - see what they said behind closed doors - AMA

Edit (5pm PT): Thanks so much all for really great questions - I'm going to pause now but will take a look over next 24 hours and try to answer any more questions. V grateful for chance to do this and to others who helped answer some of the Qs too from their perspective (shoutout u/Rebeleleven)

\--


I recently had the opportunity to attend the Berlin Global Dialogue, which has been likened to Davos but with a stronger focus on technology and AI . The lineup was impressive: Hermann Hauser, the founder of ARM, executives from OpenAI and ASML, and a mix of founders from emerging startups tackling everything from quantum ML to supply chain optimization. Even leaders like President Macron and the German Vice Chancellor were there, engaging with critical tech issues that impact us all.

As the CEO of Codesmith – a small, independent tech school with a data science and machine learning research group (last year we contributed to TensorFlow) – I was invited to announce our latest endeavor: Codesmith’s AI & ML Technical Leadership Program.

I shared this experience in an AMA on r/technology and had a great conversation—but the depth of questions around ML/AI didn’t quite match

Is anyone using Whitenoise with CloudFront in 2024?

So, I recently built a web app using just good old fullstack Django and I'm serving my assets locally with Whitenoise. When I moved to production, I configured CloudFront according to the Whitenoise docs (https://whitenoise.readthedocs.io/en/stable/django.html#use-a-content-delivery-network), but apparently these docs are very out of date (there's this issue from 2020 commenting on this https://github.com/evansd/whitenoise/issues/264) and I have been facing some weird bugs. All assets served by cloudfront are just 301 redirects, so each asset file is being served twice, apparently. Not only that, there's also a weird CORS error with a font I'm serving locally, without any other external CDNs.

Has anyone had any success using cloudfront to serve assets together with whitenoise? Does this setup even make sense anymore now that cloudfront is able to compress with both gzip and brotli?
