Welcome to issue 648 of Python Weekly. Let's get straight to the links this week.

News

Fake job interviews target developers with new Python backdoor
A new campaign called "Dev Popper" is targeting software developers with fake job interviews in an attempt to trick them into installing a Python remote access trojan (RAT). The developers are asked to perform tasks supposedly related to the interview, like downloading and running code from GitHub, in an effort to make the entire process appear legitimate.

Articles, Tutorials and Talks

Mojo Lang - Tomorrow's High Performance Python?

In this episode we explore why Mojo was created, and what it offers to Python programmers and non-Python programmers alike. How is it built for performance, and which performance features matter? What’s its take on functional programming and type systems? And can it marry the high-level programming of Python with the low-level programming of LLVM/MLIR?

Django: An admin extension to prevent state leaking between requests
Here’s a small protection I added to a project a few years ago. I was considering it again since I saw a similar potential bug in a Django middleware.

Local LLM-as-judge evaluation with lm-buddy, Prometheus and llamafile
This post examines how different software components came together to allow LLM-as-judge evaluation without the need for expensive GPUs. All the components were built with and chosen for their user control, open source nature, and interoperability.

How to Build a Crystal Image Search App with Vector Search
A demonstration of how to build an application to store and query data on crystals and precious stones using Astra DB. Built with RAGStack, this web app leverages the CLIP model to provide multi-modal search to retrieve data on all kinds of crystals.

Poor mans autoreload server in single file python on linux
The article describes a simple Python server that provides automatic browser page reload on content change, without requiring any additional setup or configuration. The server acts as a regular file server but also serves WebSocket messages over a specified path to trigger the page reload.

A Beginner’s Guide to Vector Embeddings
In this article, we’ll examine vector embeddings in depth, including the types of vector embeddings, how neural networks create them, how vector embeddings work, and how you can create embeddings for your data.

How to prevent data leakage in pandas & scikit-learn
What is data leakage, why is it problematic, and how can you prevent it when working on a supervised Machine Learning problem in Python?

Patching requests for fun and (concurrent) profit
Because life is too short to spam calls to SSL_CTX_load_verify_locations().

Sleepsort: Sorting while sleeping
The post introduces the "sleepsort" algorithm, a quirky sorting method that utilizes thread sleep times to sort integers in ascending order. It provides a playful yet insightful exploration of the algorithm's functionality and limitations.

Stream your voice clone
We'll turn your voice into an infinitely-scalable instrument with Django.

Asyncio Coroutine Object Methods in Python
We can define coroutine methods on custom Python objects. This allows methods on custom Python objects to use async/await syntax, such as awaiting other coroutines and tasks and allows the custom coroutine methods themselves to be awaited within our asyncio programs. In this tutorial, you will discover how to define object methods as coroutines.

TypeIs does what I thought TypeGuard would do in Python
The article discusses the differences between the TypeGuard and TypeIs type annotations in Python. It explains that TypeIs has more intuitive behavior compared to TypeGuard, especially when dealing with union types, and recommends using TypeIs over TypeGuard in most cases.
