Hundreds of Python enthusiasts, professionals, and maintainers gather at PyConES each year to share what they've built and learned. This kind of community work keeps open source healthy long after the conference ends.
We're thrilled to be supporting as a Silver Sponsor.

Pratham Hole calls it curiosity-driven development. During his NumPy internship at Quansight, he kept running into terms and concepts he didn't know. Each time, he looked them up and kept digging until they clicked.

The ABI is the part of the CPython API a compiler never checks for you, and it's why bugs like this turn into segfaults instead of build errors. Nathan Goldbaum lays out the mechanics in his EuroPython talk.

Sparse array formats are important. Coordinate storage, CSR, dense, each trades off differently depending on your data.
Mateusz Sokół laid out the landscape of sparse computing in Python at EuroPython and introduced Finch, a compiler built to unify it. https://t.co/AhZpe17ZYH

Open source grows as people build it, one contribution at a time. New contributors need clear paths in. Projects need people willing to mentor them.

Quansight Quarterly shares the stories from that work. Code, governance, and the people behind both.
