Welcome to issue 582 of Python Weekly. Happy New Year! I hope everyone had a nice holiday break.

News

Compromised PyTorch-nightly dependency chain between December 25th and December 30th, 2022.
PyTorch-nightly Linux packages installed via pip during that time installed a dependency, torchtriton, which was compromised on the Python Package Index (PyPI) code repository and ran a malicious binary. This is what is known as a supply chain attack and directly affects dependencies for packages that are hosted on public package indices.

Polars: The Next Big Python Data Science Library... written in Rust?

This video explains everything you need to get started coding with polars. Polars is a multi-threaded DataFrame library, meaning that it allows using all the cores of a computer at the same time to achieve its full processing potential. It's been shown to have huge performance gains over pandas.

Perf engineering with Python 3.12
3.12 brings perf profiling! In this article we take a look at how the new perf profiling support helps reduce our dummy Python script from 36 seconds to 0.8 seconds. We’ll introduce the Linux tool perf and also FlameGraph.pl, look at some disassembly and go bug hunting.

Concurrent Programming in Python
Concurrent programming refers to a type of programming focused on executing independent tasks at the same time. Unlike traditional programming where instructions or tasks are executed one after the other, concurrent programming allows multiple tasks to make progress at the same time. It facilitates other types of programming, such as parallel programming where tasks are executed simultaneously on separate CPUs. In this tutorial, you will discover concurrent programming in Python.

Turning Google smart speakers into wiretaps for $100k
The author was recently awarded a total of $107,500 by Google for responsibly disclosing security issues in the Google Home smart speaker that allowed an attacker within wireless proximity to install a “backdoor” account on the device, enabling them to send commands to it remotely over the Internet, access its microphone feed, and make arbitrary HTTP requests within the victim’s LAN (which could potentially expose the Wi-Fi password or provide the attacker direct access to the victim’s other devices). This post goes in to the details of these security issues.

Lazy Evaluation Using Recursive Python Generators
We all are familiar with Python's generators and all their benefits. But, what if I told you that we can make them even better by combining them with recursion? So, let's see how we can use them to implement "lazy recursion" and supercharge what we already do with generators in Python!

JupySQL: Better SQL in Jupyter
We forked ipython-sql and are actively developing it to bring a modern SQL experience to Jupyter! We’ve already built some great features, such as SQL query composition and plotting for large-scale datasets!
