Michael #1: dbos-transact-py

• DBOS Transact is a Python library providing ultra-lightweight durable execution.


• Durable execution means your program is resilient to any failure.


• If it is ever interrupted or crashes, all your workflows will automatically resume from the last completed step.


• Under the hood, DBOS Transact works by storing your program's execution state (which workflows are currently executing and which steps they've completed) in a Postgres database.


• Incredibly fast, for example 25x faster than AWS Step Functions.

Brian #2: Typed Python in 2024: Well adopted, yet usability challenges persist

• Aaron Pollack on Engineering at Meta blog


• “Overall findings
  
  
  
  • 88% of respondents “Always” or “Often” use Types in their Python code.
  
  
  • IDE tooling, documentation, and catching bugs are drivers for the high adoption of types in survey responses,
  
  
  • The usability of types and ability to express complex patterns still are challenges that leave some code unchecked.
  
  
  • Latency in tooling and lack of types in popular libraries are limiting the effectiveness of type checkers.
  
  
  • Inconsistency in type check implementations and poor discoverability of the documentation create friction in onboarding types into a project and seeking help when using the tools. “
  
  


• Notes
  
  
  
  • Seems to be a different survey than the 2023 (current) dev survey. Diff time frame and results. July 29 - Oct 8, 2024
  
  

Michael #3: RightTyper

• A fast and efficient type assistant for Python, including tensor shape inference

Brian #4: Lazy self-installing Python scripts with uv

• Trey Hunner


• Creating your own ~/bin full of single-file command line scripts is common for *nix folks, still powerful but underutilized on Mac, and trickier but still useful on Windows.


• Python has been difficult in the past to use for standalone scripts if you need dependencies, but that’s no longer the case with uv.


• Trey walks through user scripts (*nix and Mac)
  
  
  
  • Using #! for scripts that don’thave dependencies
  
  
  • Using #! with uv run --script and /// script for dependencies
  
  
  • Discussion about how uv handles that.
