<p>Python’s Global Interpreter Lock has shaped the way developers build concurrent applications for nearly three decades. While the GIL simplified the CPython ecosystem, it also imposed well-known limits on CPU-bound work and multithreaded scalability. With the introduction of free-threaded Python (3.14t), that is about to change.</p> <p>This talk explores the history and purpose of the GIL, why it existed for so long, and the innovations that finally made its removal viable. We’ll look at ...

Now we're drowning in a sea of indentation-sensitive, template-riddled, Jinja2-abused configuration files that make even the most battle-hardened sysadmins weep into their mechanical keyboards.</p> <p>Enter <strong>PyInfra</strong>—where your infrastructure is <em>actually</em> code. Real Python. With loops that don’t require learning a DSL. With functions that are... wait ...

This has traditionally often required managing complex systems in the cloud or large data centers. The talk will demonstrate how all this can be greatly simplified by applying modern tools for the task: Python and DuckDB, both open source and readily available to run on most systems - even your notebook.</p> <p><em>Description:</em></p> <p><strong>ETL</strong> stands for "extract, ...
