Real-time chat application with Django + Firebase Cloud Messaging.
I need to create a real-time chat application where users can send messages, videos, pictures, voice messages, etc.
There will be one-to-one chats or group chats for users.
Now my question is about the tech stack, basically up until now I have been writing DRF API and I am thinking of using Django channels with FCM for push notifications and I wanted to know if this is a good idea or if I should do something else.
Also, I have heard about Firebase's real-time database and wanted to ask if I can use it instead of Django channels.
I am a beginner and a bit lost so please any recommendation or suggestion will be appreciated.

The trouble with all
https://www.gauge.sh/blog/the-trouble-with-all
I wrote a blog post discussing the issues that __all__ in Python has - particularly it's lack of ability to enforce public APIs despite letting you define them. It led to a fun exploration of importlib and me writing my first import hook! Code here - https://github.com/gauge-sh/hook/blob/main/hook.py
Curious to hear folks thoughts on this problem, especially as compared to other languages! How do you enforce interfaces on your Python modules?

Is Unlimited Context Length really possible? At what cost?
Amanda Bertsch, author of 2023 NeurIPS paper Unlimiformer, will describe the architecture and take questions at this Friday's Oxen.ai Paper Club.
Greg Schoeninger u/FallMindless3563, Oxen CEO and Master of Plain Speak, will help interp the concept and relate it to other papers we have reviewed.
Call: https://oxen.ai/community
The trick asserted to make Unlimited Context Length possible: Offload the cross attention calc to a K-Nearest Neighbors (K-NN) index.
I tweeted someone's clever animation of K-NN here: https://x.com/mustafarrag/status/1817647917059944474

Mulitnomial Logistic model but for mixed effects
Hello, I wanted some suggestions on how to implement a mixed effects multinomial logistic regression model for my data.
A little context on my data- I am trying to predict how people categorize an object (4 possible options here - categorical) based on 2 types of inputs (both inputs are categorical variables with 4 different categories each).
Initially, I thought a normal multinomial logit model would work, but it was brought to my attention that I had repeated measures in my data. Which had me looking up mixed effects models.
But, mixed effects multinomial logistic regression for categorical variables sounds....complicated.
Any suggestions on how to implement this (packages/code samples etc) or any better/easier alternatives for this type of data, would be welcome.

Claude playing nicer with django
If you use claude / chatgpt for working on django code, you probably already bumped into the problem that claude will guess the model fields for the models it can't see - producing crappy results.
To get around it, make a management command that describes models accross one or more apps, printing the description to console in a dense format.
Now claude doesn't make mistakes when he is referencing other models. Just ask claude for a list of the models he needs more information about before he starts working, copy the list into the management command and get a console log of the description in an dense format.
I'm interested in any other tricks people have to make claude or chatgpt play better with django.
Instructions and code...
Use it like this:
python manage.py describe_models model1 model2 model3
or
python manage.py describe_models app
or
python manage.py describe_models --all
Here is the management command:

Advice on Usage Limited Subscription Model Using Stripe Payments 🤑
What would be the best way to implement this, I feel that it is a fairly common business model but can't find any resources online. I am using stripe payments.
I believe I would require users to sign up immediately so I can track their usage.
I plan on offering a free trial e.g. 10 uses of my SaaS (each is an openai call).
Then if the user wants to continue using, they have to purchase a subscription.
When subscribed they have a maximum usage e.g. 100 uses per month.
Alternatively, is there a similar business model that I could implement with stripe which I can't be exploited by lots of openai api calls which could get expensive?
My current setup:
Flask backend
OpenAI API for summarization
Simple HTML/CSS/JS frontend
Stripe for payments
Any advice, resources, or code examples would be greatly appreciated. Thanks in advance!

ArchiveFile: Unified interface for tar, zip, sevenzip, and rar files
PREVIOUS POST
#### What My Project Doesarchivefile is a wrapper around `tarfile`, `zipfile`, `py7zr`, and `rarfile`.
The above libraries are excellent when you are dealing with a single archive format but things quickly get annoying when you have a bunch of mixed archives such as .zip, .7z, .cbr, .tar.gz, etc because each library has a slightly different syntax and quirks which you need to deal with.archivefile wraps the common methods from the above libraries to provide a unified interface that takes care of said differences under the hood. However, it's not as powerful as the libraries it wraps due to lack of support for features that are unique to a specific archive format and library.
#### Target audience
Anyone who's using python to deal with different archive formats
#### Comparison
- ZipFile, TarFile, RarFile, and py7zr - These are libraries that mine wraps since each of them can only deal with a single archive format
- shutil - Shutil can only deal with zipfile and tarfile and only allows full packing or full extraction.
- patool - Excellent library that deals with wider range of formats than mine but in doing so it provides less granular control over each
ArchiveFile falls somewhere between the powerful dedicated library and the

ENVKEY Shutting Down - Alternatives for secrets / keys?
Hey all, ENVKEY just announced they're shutting down. What is everyone using for secrets / keys?
Here is the email from ENVKEY:
>Today I have some difficult news to share. After nearly 7 years of working on EnvKey, I’ve decided to begin winding down the company. In order to give all customers and users plenty of time to transition away, EnvKey will wind down over the next 6 months. EnvKey Cloud will shut down on February 1st, 2025 and then the EnvKey company will be dissolved.
>This has been a stressful and emotional decision for me, but unfortunately I’ve had to accept that continuing to run EnvKey is no longer financially sustainable for myself and my family, and therefore it’s time to move on.
>I understand that this may come as a surprise and a disappointment. I’m deeply honored by the trust that hundreds of organizations and thousands of users have placed in EnvKey over the years, and I regret giving you extra work to do in transitioning away.
>I hope that the gradual wind down period will help to soften any negative impact. Additionally, I've been in touch with the CEO of Infisical, another secrets management platform that is also open source, end-to-end encrypted, and similar in its spirit and

I want to change my VPS from Linode to a new provider that supports only IPv4. The new service only gives me the vps, there is no interface like Linode where I can add domain names point to the VPS IP.
Could anyone provide guidance on how to setup my domains to point to my new vps IP?

Anyone know of any communities dedicated to software toys?
By "software toys" I mean silly little applications/scripts/whatever that serve no purpose other than to amuse, but don't quite meet the definition of a game.
For example, I once wrote a Python script that encoded text as mosaic of colored squares.
Or another time I wrote a non-interactive simulation of a crew of NPCS that explored a fictional ocean and posted their discoveries on Reddit.
Just silly, dumb things like that. It doesn't necessarily have to be strictly for Python but since that's what I normally code in I thought I'd ask here.

R Annotation Vocabulary (Might Be) All You Need
Paper link: https://www.biorxiv.org/content/10.1101/2024.07.30.605924v1
Abstract:
>
Protein Language Models (pLMs) have revolutionized the computational modeling of protein systems, building numerical embeddings that are centered around structural features. To enhance the breadth of biochemically relevant properties available in protein embeddings, we engineered the Annotation Vocabulary, a transformer readable language of protein properties defined by structured ontologies. We trained Annotation Transformers (AT) from the ground up to recover masked protein property inputs without reference to amino acid sequences, building a new numerical feature space on protein descriptions alone. We leverage AT representations in various model architectures, for both protein representation and generation. To showcase the merit of Annotation Vocabulary integration, we performed 515 diverse downstream experiments. Using a novel loss function and only $3 in commercial compute, our premier representation model CAMP produces state-of-the-art embeddings for five out of 15 common datasets with competitive performance on the rest; highlighting the computational efficiency of latent space curation with Annotation Vocabulary. To standardize the comparison of de novo generated protein sequences, we suggest a new sequence alignment-based score that is more flexible and biologically relevant than traditional language modeling metrics. Our generative model, GSM, produces high alignment scores from annotation-only prompts with a BERT-like generation scheme. Of particular

Component Library Solution: django-lookbook
Hi, I'd like to share an Django component library solution **django-lookbook** here.
I want something like "StoryBook" to Django but existing solutions of the Django community did not make me satisfied, so I built it myself.
Below are some features you might be interested:
## Pluggable app
It is a classic Django pluggable app which can be integrated with your Django project within minutes.
No matter your Django project use jQuery, Vanilla JS, Alpine.js, HTMX, Stimulus.js or other frontend solution, **it can work with them all**.
## Preview
Let's say you have a custom `Modal` component in your Django project, built with `Alpine.js`, and it supports different modal size `small`, `medium`, `large` based on the `Tailwind CSS`
How to make other team mates quickly understand the usage? Instead of digging the Django templates?
We can create three previews for the Modal and developers can directly check the final result in the component library.
class ModalComponentPreview:
def small_modal():
def medium_modal():
def large_modal():
As you can see, we can create previews and put them in one Python class, and the syntax is very similar with writing unittests

Flask for Campus Placements
Hey guys! I am a final-year college student and have worked on multiple Flask applications in the past. My college would have companies visiting the campus for placements in a few days. Based on Flask practice and learning, I feel petrified regarding what to expect from the interviewers and what to focus on. I would be extremely grateful if some suggestions based on / regardless of my projects could be given.
Also, I feel as if I am in a fix as I love Flask and wish to work on new projects, but then considering the time required to map out a project seems too irrational, so should I work on improving pre-existing projects or work on some basic new ones exploring more into the domain? Kindly let me know! Cheers!

There is so much noise in the reviews every year. Some good work that the authors are proud of might get a low score because of the noisy system, given that NeurIPS is growing so large these years. We should keep in mind that the work is still valuable no matter what the score is.
