Project mention: Smoke, stress, spike, soak, and recovery: 5 essential load test profiles | news.ycombinator.com | 2024-08-15
Hi everyone!
Long time lurker, first time poster here. I'm the maintainer of Locust (https://github.com/locustio/locust), and this is the second part of my series about load testing.
Let me know what you think!

Project mention: How to Get Started with Scikit-Learn: A Beginner-Friendly Guide to Machine Learning in Python | dev.to | 2025-04-24
As is the case with most Python libraries, it is open-source and free-to-use, making it easily accessible by anyone willing to learn machine learning, and it is built upon other open-source libraries within Python, like SciPy for advanced scientific operations, NumPy for efficient numerical computations, Matplotlib for data visualization, and Cython for increased efficiency and speed, similar to that of C/C++.

Project mention: Do you need Redis? PostgreSQL does queuing, locking, and pub/sub | news.ycombinator.com | 2024-11-03
Django has caching built in with support for Redis, and it also has an in-memory caching option which they label as “not for production” (because if you have multiple instances of Django serving requests, their in-memory caches will diverge which is...bad).
But for lots of cases, especially internal business tools, we can scale up a single instance for a long time, and this in-memory caching makes things super fast.
There’s a library, django-cachalot [1], that handles cache invalidation automatically any time a write happens to a table. That’s a rather blunt way to handle cache invalidation, but it’s wonderful because it will give you a boost for free with virtually no effort on your part, and if your internal business app has infrequent updates it basically runs entirely in RAM, and falls back to regular database queries if the data isn’t in the cache.
