Will's Tweet announcing that I was going to join Textualize
"In a fantasy tech startup, who would you hire?
For me it would be @davepdotorg and @mathsppblog
But it's no fantasy. Dave and Rodrigo will be starting at Textualize. They will be helping me build Textual. The TUI framework for #Python that will eat some of the browser's lunch."
A Retrospective on Requests
As per the title: a retrospective of requests.
Possibly killer quote: "After receiving our first security disclosure, I was told that Requests wasn't a serious project but instead one person's art project and thus we shouldn't fix the vulnerability. This was despite the project being touted as being used by multiple international government agencies, political campaigns, and boasting about it's #1 download spot on PyPI. So when I say it might be artful, I'm trying to take a neutral stance on what is art and what isn't art and whether the internals of Requests are actually beautiful art."
(How to Write a (Lisp) Interpreter (in Python))
This page has two purposes: to describe how to implement computer language interpreters in general, and in particular to build an interpreter for most of the Scheme dialect of Lisp using Python 3 as the implementation language. I call my language and interpreter Lispy (lis.py). Years ago, I showed how to write a semi-practical Scheme interpreter Java and in in Common Lisp). This time around the goal is to demonstrate, as concisely and simply as possible, what Alan Kay called "Maxwell's Equations of Software."

How to improve Python packaging, or why fourteen tools are at least twelve too many
"Join me on a journey through packaging in Python and elsewhere. We’ll start by describing the classic packaging stack (involving setuptools and friends), the scientific stack (with conda), and some of the modern/alternate tools, such as Pipenv, Poetry, Hatch, or PDM. We’ll also look at some examples of packaging and dependency-related workflows seen elsewhere (Node.js and .NET). We’ll also take a glimpse at a possible future (with a venv-less workflow with PDM), and see if the PyPA agrees with the vision and insights of eight thousand users."
