Brian #1: NumFOCUS concerns

  • Suggested by Pamphile Roy
  • Write up of the current challenges faced by NumFOCUS, by Paul Ivanov (one of the OG of Scientific Python: Jupyter, Matplotlib, etc.)
    • Struggling to meet the needs of sponsored and affiliated projects.
    • In February, NumFOCUS announced it is moving in a new direction.
    • NumFOCUS initiated an effort to run an election for open board seats and proposed changing its governance structure.
    • Some projects are considering and actively pursuing alternative venues for fiscal sponsorship.
    • Quite a bit more detail and discussion in the article.
  • NumFOCUS covers a lot of projects
    • NumPy, Matplotlib, pandas, Jupyter, SciPy, Astropy, Bokeh, Dask, Conda, and so many more.

Michael #2: leaping pytest debugger llm

  • You can ask Leaping questions like:
    • Why am I not hitting function x?
    • Why was variable y set to this value?
    • What was the value of variable x at this point?
    • What changes can I make to this code to make this test pass?

Brian #3: Extra, Extra, Extra,

Michael #4: PyPI has completed its first security audit

  • Trail of Bits spent a total of 10 engineer-weeks of effort identifying issues, presenting those findings to the PyPI team, and assisting us as we remediated the findings.
  • Scope: The audit was focused on "Warehouse", the open-source codebase that powers
  • As a result of the audit, Trail of Bits detailed 29 different advisories discovered across both codebases. When evaluating severity level of each advisory, 14 were categorized as "informational", 6 as "low", 8 as "medium" and zero as "high".
