abstraction: a concrete case story, software patterns, and ultimately a
living systems paradigm.

“A
fool with a tool is still a fool” examines how AI is reshaping software
development—what it truly does well, where it fails spectacularly, and
how to use it responsibly rather than recklessly. Drawing on real-world
wins and faceplants (including “vibe coding”), the talk distills
practical guardrails, governance, and senior-level responsibilities for
shipping trustworthy systems.

A
recap on thread safety and synchronisation primitives. As more
developers adopt free-threaded Python, understanding thread safety
becomes critical - not just nice to have. This talk explores all
essential synchronisation primitives from Python's threading module
through a practical dice game simulation scenario. You'll learn to
identify and fix race conditions, understand what the GIL was
protecting, and discover patterns to ensure your code works correctly in
the free-threaded future.

Typing
in Python starts to take shape via many PEPS and we are going to
explore the evolution of it. In this talk, we will look at how do we get
here, with all the tools that can be used to enforce strong typing in
Python, a genetically dynamic typing language.

this talk, we’ll explore how to make accessibility-first development
part of your organization’s DNA. You’ll learn how assistive technologies
interact with the accessibility tree, what accessibility-first

still exist around accessibility.
