WhatsApp Wrapped with Polars & Plotly: Analyze chat history locally

I've always wanted something like Spotify Wrapped but for WhatsApp. There are some tools out there that do this, but every one I found either runs your chat history on their servers or is closed source. I wasn't comfortable with all that, so this year I built my own.

## What My Project Does

WhatsApp Wrapped generates visual reports for your group chats. You export your chat from WhatsApp (without media), run it through the tool, and get an HTML report with analytics. Everything runs locally or in your own Colab session. Nothing gets sent anywhere.

Here is a Sample Report.

Features include message counts, activity patterns, emoji stats, word clouds, and calendar heatmaps. The easiest way to use it is through Google Colab - just upload your chat export and download the report. There's also a CLI for local use.

## Target Audience

Anyone who wants to analyze their WhatsApp chats without uploading them to someone else's server. It's ready to use now.

## Comparison

Unlike other web tools that require uploading your data, this runs entirely on your machine (or your own Colab). It's also open source, so you can see exactly what it does with your chats.

Tech: Python, Polars, Plotly, Jinja2.

I made FastAPI Clean CLI – Production-ready scaffolding with Clean Architecture

Hey r/Python,

What My Project Does
FastAPI Clean CLI is a pip-installable command-line tool that instantly scaffolds a complete, production-ready FastAPI project with strict Clean Architecture (4 layers: Domain, Application, Infrastructure, Presentation). It includes one-command full CRUD generation, optional production features like JWT auth, Redis caching, Celery tasks, Docker Compose orchestration, tests, and CI/CD.

Target Audience
Backend developers building scalable, maintainable FastAPI apps – especially for enterprise or long-term projects where boilerplate and clean structure matter (not just quick prototypes).

Comparison
Unlike simpler tools like cookiecutter-fastapi or manage-fastapi, this one enforces full Clean Architecture with dependency injection, repository pattern, and auto-generates vertical slices (CRUD + tests). It also bundles more production batteries (Celery, Prometheus, MinIO) in one command, while keeping everything optional.

Quick start:
pip install fastapi-clean-cli
fastapi-clean init --name=my_api --db=postgresql --auth=jwt --docker

It's on PyPI with over 600 downloads in the first few weeks!

GitHub: https://github.com/Amirrdoustdar/fastclean
PyPI: https://pypi.org/project/fastapi-clean-cli/
Stats: https://pepy.tech/project/fastapi-clean-cli

This is my first major open-source tool. Feedback welcome – what should I add next (MongoDB support coming soon)?

Thanks! 🚀

Spark can spill to disk why do OOM errors still happen

I was thinking about Spark’s spill to disk feat. My understanding is that spark.local.dir acts as a scratchpad for operations that don’t fit in memory. In theory, anything that doesn’t fit should spill to disk, which would mean OOM errors shouldn’t happen.

Here are a few scenarios that confuse me

A shuffle between executors. The receiving executor might get more data than RAM can hold but shouldn’t it just start writing to disk
A coalesce with one partition triggers a shuffle. The executor gathers a large chunk of data. Spill-to-disk should prevent OOM here too
A driver running collect on a massive dataset. The driver keeps all data in memory so OOM makes sense, but what about executors
I can’t think of cases where OOM should happen if spilling works as expected. Yet it does happen.

want to understand what actually causes these OOM errors and how people handle them

django-allauth move from GitHub to Codeberg a Year Ago Looking Smarter Every Day

tl;dr: django-allauth’s move from GitHub to Codeberg a year ago got a lot of doubt at first, but it is looking wiser by the day now with GitHub’s new fees for private repo runners coming in 2026. This shows Microsoft’s push to monetize more, which hurts trust in their freemium setup, and makes devs less likely to suggest it for work. What alternatives do you use for home and work?

A year ago, django-allauth moved from Microsoft GitHub to Codeberg, drawing skepticism over visibility, contributions, and security. But with GitHub’s new $0.002/minute charge for self-hosted runners in private repos starting March 2026 (sparking complaints about Microsoft’s profit focus), it is more evidence the move was smart. They dodged a platform that is increasingly monetizing features.

Many companies keep open source free to hook users into paid private or commercial tiers. Tailscale (I’m a big fan) does this well with affordable home plans that encourage enterprise adoption as they explain in this blog post, which is a positive approach. But when companies like Micro$oft make these changes and erode trust, they negate the model they originally adopted. People start to recognize the slow boil and eventually jump out of the pot, hurting the

Released datasetiq: Python client for millions of economic datasets – pandas-ready

Hey r/Python!

I'm excited to share datasetiq v0.1.2 – a lightweight Python library that makes fetching and analyzing global macro data super simple.

It pulls from trusted sources like FRED, IMF, World Bank, OECD, BLS, and more, delivering data as clean pandas DataFrames with built-in caching, async support, and easy configuration.

\### What My Project Does

datasetiq is a lightweight Python library that lets you fetch and work millions of global economic time series from trusted sources like FRED, IMF, World Bank, OECD, BLS, US Census, and more. It returns clean pandas DataFrames instantly, with built-in caching, async support, and simple configuration—perfect for macro analysis, econometrics, or quick prototyping in Jupyter.

Python is central here: the library is built on pandas for seamless data handling, async for efficient batch requests, and integrates with plotting tools like matplotlib/seaborn.

\### Target Audience

Primarily aimed at economists, data analysts, researchers, macro hedge funds, central banks, and anyone doing data-driven macro work. It's production-ready (with caching and error handling) but also great for hobbyists or students exploring economic datasets. Free tier available for personal use.

\### Comparison

Unlike general API wrappers (e.g., fredapi or pandas-datareader), datasetiq unifies multiple sources (FRED + IMF + World Bank + 9+ others) under one simple interface, adds

Rust and OCaml-style exhaustive error and None handling for Python

I had this Idea for over 3 years already. One time my manager called me at 3 AM on Friday and he was furious, the app I was working on crashed in production because of an unhandled error, while he was demoing it to a huge prospect. The app was using a document parsing lib that had infinite amount of edge cases (documents are messy, you can't even imagine how messy they can be). Now I finally implemented this idea. It's called Pyrethrin.

* **What My Project Does** \- It's a library that lets you create functions that explicitly define what exceptions it can raise or that it can return a None, and the other function using this one has to exhaustively implement all the cases, if any handle is missing or not handled at all, Pyrethrin will throw an error at "compile" time (on the first run in case of Python).
* **Target Audience** \- the tool is primarily designed for production use, especially in large Python teams. Other target audience is Python library developers, they can "shield" their library for their users to gain their trust (it will fail on their end way less than without Pyrethrin)
* **Comparison** \- I
