• Check out the video

Brian #2: xz back door

• In case you kinda heard about this, but not really.
• Very short version:
  • A Microsoft engineer noticed a performance problem with ssh and tracked it to a particular version update of xz.
  • Further investigations found a multi-year installation of a fairly complex back door into the xz by a new-ish contributor. But still contributing over several years. First commit in early 2022.
  • The problem is caught. But if it had succeeded, it would have been bad.
  • Part of the issue of how this happened is due to having one primary maintainer on a very widely used tool included in tons-o-Linux distributions.
• Some useful articles
  • Everything I Know About the XZ Backdoor - Evan Boehs - recommended read
• Don’t think your affected? Think again if you use homebrew, for example:
  • Update and upgrade Homebrew and xz versions
• Notes
  • Open source maintenance burnout is real
  • Lots of open source projects are maintained by unpaid individuals for long periods of time.
  • Multi-year sneakiness and social bullying is pretty hard to defend against.
  • Handing off projects to another primary maintainer has to be doable.
    • But now I think we need better tools to vet contributors.
    • Maybe? Or would that just suppress contributions?
• One option to help with burnout:
  • JGMM, Just Give Maintainers Money: Software Needs To Be More Expensive - Glyph

Michael #3: LPython

• LPython aggressively optimizes type-annotated Python code. It has several backends, including LLVM, C, C++, and WASM.
• LPython’s primary tenet is speed.
• Play with the wasm version here: dev.lpython.org
• Still in alpha, so keep that in mind.

Brian #4: dramatic

• Trey Hunner
• More drama in the software world. This time in the Python.
• Actually, this is just a fun utility to make your Python output more dramatic.
• More fun output with terminaltexteffects
  • suggested by Allan
