Git rebase -I is not that scary

The fear surrounding Git rebase -i is often due to misunderstanding its functionality, which is simply opening a text file for editing commit history. Interactive rebasing is a powerful tool that can make life easier, not harder, once you understand it creates new commits and moves the branch pointer, with safety nets like the reflog and pre-rebase backups.

Overloaded Overloading

https://powerfulpython.com/static/ppbook/ppbook-oreilly-cover3.png
Python does not support method overloading like Java, but it allows operator overloading through magic methods like __add__ which can be used for different operations. To achieve method overloading in Python, you can implement it manually or use the @singledispatch decorator from the functools module.

LLM Usage in Debian: Three Proposals

The Debian project proposes to ban contributions written with the use or assistance of large language models (LLMs) or other generative AI tools due to concerns over stability, accuracy, and legal status. The proposal aims to protect Debian's reputation for stability and reliability, as well as the interests of its volunteers, by prohibiting LLM-assisted contributions to the project.

Clinical failure rates over the decades: yikes

A new paper estimates the clinical failure rate of the biopharma industry since the 1960s, finding it to be extremely high, with 91% of candidates failing in the 2000s and 2010s. This rate is unsustainable and explains the industry's high stakes and pressure to succeed.
