R Automating the Search for Artificial Life with Foundation Models
Happy to release this new work, Automating the Search for Artificial Life with Foundation Models, right before the holiday season!
Blog: https://sakana.ai/asal/
Paper: https://arxiv.org/abs/2412.17799
Website version of paper: https://pub.sakana.ai/asal/
GitHub: https://github.com/SakanaAI/asal
Abstract
With the recent Nobel Prize awarded for radical advances in protein discovery, foundation models (FMs) for exploring large combinatorial spaces promise to revolutionize many scientific fields. Artificial Life (ALife) has not yet integrated FMs, thus presenting a major opportunity for the field to alleviate the historical burden of relying chiefly on manual design and trial-and-error to discover the configurations of lifelike simulations. This paper presents, for the first time, a successful realization of this opportunity using vision-language FMs. The proposed approach, called Automated Search for Artificial Life (ASAL), (1) finds simulations that produce target phenomena, (2) discovers simulations that generate temporally open-ended novelty, and (3) illuminates an entire space of interestingly diverse simulations. Because of the generality of FMs, ASAL works effectively across a diverse range of ALife substrates including Boids, Particle Life, Game of Life, Lenia, and Neural Cellular Automata. A major result highlighting the potential of this technique is the discovery of previously unseen Lenia and Boids lifeforms, as well as cellular automata that are open-ended like Conway's Game of Life. Additionally,

A smart dollhouse that understands natural language commands and uses MicroPython, REST, LLMs
What My Project Does: I created a smart dollhouse that can understand commands in any language and control IoT devices through natural conversation. Using a Raspberry Pi Pico W running MicroPython, I implemented a REST API server that controls LEDs, motors, and sensors. The system uses LLMs to translate natural language commands (in any language!) into API calls. For example, you can say "turn on the yellow LED" in English, "выключи желтый led" in Russian, or "Apaga la led amarilla" in Spanish, and the system will understand and execute the command.
Target Audience: This is primarily an educational/demonstration project aimed at:
Python developers interested in IoT and LLMs
Makers and hobbyists looking to experiment with natural language interfaces
Anyone learning about REST APIs and microcontrollers
Students and educators exploring practical applications of LLMs
Comparison: While there are many IoT projects using voice assistants like Alexa (which I started with), my approach differs in several ways:
1. Language Flexibility: Unlike Alexa, which requires exact phrases, this system understands natural language in any language
2. Lightweight Implementation: Uses Microdot instead of Flask, making it suitable for microcontrollers
3. HATEOAS Implementation: Implements proper REST API design principles for better discoverability
4. Open Architecture: Unlike commercial solutions, this is fully

It took me way longer than I'd like to admit to realize how crucial setting up CustomUser is before the first migration.
When I built my first solo Django project, one of the biggest headaches I ran into—and the first thing that made me cry into my coffee—was thinking I had set up the custom user model correctly, only to be hit with a bunch of errors. After some confusion, I realized that since I’d already made migrations, my only choices were to refactor my database or delete it and start over. It was extra terrible because I thought I was done with the project, but failing to set up the custom user model properly ended up costing me another four hours of work. It really made me panic and feel like my whole project was doomed.
Recently I’ve been thinking about what beginners might need to help them learn Django in the smoothest and fastest way possible, and felt that helping them avoid this mistake could be really helpful. So I made a YT video where I basically beg people to set up a custom user and quickly show them how - as it really just takes seconds.
For anyone else who’s had a similar experience, what was your "Django nightmare" moment? Any tips you’d give to those just starting out?

Hi guys! Today I am releasing my first project and wanted some reviews on it.
What My Project Does:
My project is a simple but useful life manager, some of the things that you can do on it are:
ADD TASKS: You can add some task with a time limit and coin reward, ex: "Study for the finals, 2 days, 50 coins".
CREATE REWARDS: Also, you can create buyable rewards in the shop, example: "Watch a movie, cost: 40 coins".
KEEP TRACK OF YOUR PRODUCTIVITY: The system automatically keep track of the amount of tasks completed by day and plot them at a graph.
Target Audience:
Its meant for anyone that struggles with procrastination and productivity.
Comparison:
I wanted to create my own to make it as simple as possible to use, at the same time of maintaing the important features, tasks tracking and a clear UI
If you have some suggestion I would love to hear it and I really hope that this project helps someone out there.
So, if you want to take a look at it, its in my github at this link: https://github.com/Gabriel-Dalmolin/life\_manager

AndroidSecretary - Your personal, context-aware AI SMS secretary for Android
Hello!
I just released a new project of mine, AndroidSecretary. It uses Flask for its backend, so Python was yet again of great use for this!
What My Project Does
This project provides you with an AI assistant that responds to your SMS messages contextually. It is customizable and can respond for you when you are not available.
Target Audience
Anyone with an Android device supported by the Automate app can have fun and utilize Android Secretary.
Also, this is not meant to be used by the average person. It is meant for developers to use for educational purposes only.
Comparison
So far, there are not many (if any) projects that do what AndroidSecretary does. For reference of features:
1. Ollama & OpenAI Support (with ollama, an external computer more powerful than the phone is likely needed to run more context-wise LLM's, unless you have a phone at least 12 GB of RAM)
2. Context-based assistant responses to messages received.
3. Customization:
1. Name your assistant
2. Limit the max amount of messages per hour per user
3. Blacklist and allowlist features (allowlist overrides blacklist)
4. Block spam feature (provided you give phone contact permissions to Automate)

Django Custom User Model Migration Issue - "Lazy Reference to 'users.CustomUser'"
Hello, I'm working on a Django project where I've implemented a custom user model by subclassing AbstractUser. In my `settings.py`, I've correctly set AUTH_USER_MODEL = 'users.CustomUser'. However, when I run the migrations, I get the following error: ValueError: The field admin.LogEntry.user was declared with a lazy reference to 'users.customuser', but app 'users' doesn't provide model 'customuser'.
I’ve already made sure that the CustomUser model is correctly defined in users/models.py, and the app is listed in INSTALLED_APPS. I've also run makemigrations for the users app, but I’m still encountering this issue.
Has anyone experienced this before or can help me figure out why Django can't find the CustomUser model? Any advice would be greatly appreciated!

Python Youtube album downloader (Downloads video and splits it up into songs based on timestamps)
Purpose: Chrome fuckin sucks with memory so listening to music on YouTube uses so much ram. During exams, it gets kinda long and the amount by which it heats up gets me scared. BUTTTTT, Spotify is much better at playing music, so if only there was a way to listen to videos only on YouTube but on Spotify instead????? (there probably is but I couldn't find one that did it my way).
What My Project Does: A Python script that allows you to download an album from YouTube and split it up into songs, using a timestamps file as a reference. Note the "album" must be a YouTube video and not a playlist unfortunately :(
Target Audience: This is for anyone willing to use it. I kinda created it for myself but thought to post it here anyways
Comparison: Uses a lot of ffmpeg, so I guess that's the similar program? It's not exactly on par with any crazy video editing software but it does the job.
The only thing that kinda sucks is that the timestamps have to be in a certain format otherwise it wont work, I couldn't be asked/ couldn't think of a way to make a REGEX for it. But yh

PipeFunc: Build Lightning-Fast Pipelines with Python - DAGs Made Easy
Hey r/Python!
I'm excited to share pipefunc (github.com/pipefunc/pipefunc), a Python library designed to make building and running complex computational workflows incredibly fast and easy. If you've ever dealt with intricate dependencies between functions, struggled with parallelization, or wished for a simpler way to create and manage DAG pipelines, pipefunc is here to help.
What My Project Does:pipefunc empowers you to easily construct Directed Acyclic Graph (DAG) pipelines in Python. It handles:
1. Automatic Dependency Resolution: pipefunc intelligently determines the correct execution order of your functions, eliminating manual dependency management.
2. Lightning-Fast Execution: With minimal overhead (around 15 µs per function call), pipefunc ensures your pipelines run blazingly fast.
3. Effortless Parallelization: pipefunc automatically parallelizes independent tasks, whether on your local machine or a SLURM cluster. It supports any concurrent.futures.Executor!
4. Intuitive Visualization: Generate interactive graphs to visualize your pipeline's structure and understand data flow.
5. Simplified Parameter Sweeps: pipefunc's mapspec feature lets you easily define and run N-dimensional parameter sweeps, which is perfect for scientific computing, simulations, and hyperparameter tuning.
6. Resource Profiling: Gain insights into your pipeline's performance with detailed CPU, memory, and timing reports.
7. Caching: Avoid redundant computations with multiple caching backends.
8. Type Annotation Validation: Ensures type consistency across your pipeline to catch errors

Automated generation of categories for classification D
So I can use Bart zero-shot classification to quantify the relevance of an article to a predefined set of categories but I have a bunch of articles and I want to compute categories from them and then use those categories to classify lots of articles.
I thought maybe I could convert each article to a vector using a text embedding and then use an unsupervised learning algorithm to compute clusters of related articles and then project the groups back into text, maybe by recursively summarizing the articles in each group. However, I don't actually want the constraint that sets of categories must be disjoint which, I think, k-means would impose.
How else might this be accomplished?

There are no interviews with low signal questions like "why do you want to work for us?" or "what's your biggest weakness?", also no factoid technical questions that can be looked up quickly with a web search or an AI agent.
The process is straight-forward:
* Fill out this form: [https://docs.google.com/forms/d/1Y-ESW0rrlbh24B5vnbTamHN5w6toT-WIyipLPKTEIsY/](https://docs.google.com/forms/d/1Y-ESW0rrlbh24B5vnbTamHN5w6toT-WIyipLPKTEIsY/)
* If there's an initial good fit, we'll have one call to discuss what we need and for you to show us and talk about your work.
* If we are both happy, we'll send you an initial short real task to perform on our code and payment for it.

Pivot from Flask
Hey everyone,
I recently built an app using Flask without realizing it’s a synchronous framework. Because I’m a beginner, I didn’t anticipate the issues I’d face when interacting with multiple external APIs (OpenAI, web crawlers, etc.). Locally, everything worked just fine, but once I deployed to a production server, the asynchronous functions failed since Flask only supports WSGI servers.
Now I need to pivot to a new framework—most likely FastAPI or Next.js. I want to avoid any future blockers and make the right decision for the long term. Which framework would you recommend?
Here are the app’s key features:
Integration with Twilio
Continuous web crawling, then sending data to an LLM for personalized news
Daily asynchronous website crawling
Google and Twitter login
Access to Twitter and LinkedIn APIs
Stripe payments
I’d love to hear your thoughts on which solution (FastAPI or Next.js) offers the best path forward. Thank you in advance!

PyMo - Python Motion Visualizer CLI
Hello, I have build a motion visualizer in python as a CLI script.
What My Project Does: It extracts frames from a video, offsets them and blends them using difference (blend mode from Image and Video Editing Software), applies a few filters and exports a new video.
Target Audience: This is for anyone willing to use it, mostly for fun. If you are comfortable with running scripts in a terminal, you are the target audience. I have mostly created it to see the movement of my vape clouds and that is fun and interesting.
Comparison: As this process can be achieved in any video editing software, even blender, there is not much of a comparison. The only thing that my project does, is the post processing. It just runs contrast and denoise, but that brings out details, which video editing software mostly won't give you (At least from my experience).
