• Armin’s post about launching Open Source Pledge and mixing money with open source

Michael #2: Jeff Triplet's DjangoTV

• A nice aggregation of lots of Django conference talks


• Filter by conference


• Good search as well

Brian #3: PEP 735 – Dependency Groups in pyproject.toml

• Author: Stephen Rosen, Sponsor: Brett Cannon, PEP-Delegate: Paul Moore


• Accepted. Resolotion Oct 10, 2024


• “This PEP specifies a mechanism for storing package requirements in pyproject.toml files such that they are not included in any built distribution of the project.”


• Allow us to define named groups of dependencies that can be independent of the main project.



• ex:

  
  
  

  [dependency-groups]
  
  test = ["pytest", "coverage"]
  
  docs = ["sphinx", "sphinx-rtd-theme"]
  
  typing = ["mypy", "types-requests"]
  
  typing-test = [{include-group = "typing"}, {include-group = "test"}, "useful-types"]
  
  




• “might” work like this: pip install --dependency-groups=test,typing

  
  
  
  
  
  • but tool venders are able to define how they use groups. Of course.
  
  


• Similar solutions
  
  
  
  • multiple requirements.txt files: requirements_test.txt, requirements_docs.txt, etc.
    
    
    
    • no standard naming convention, not standardized
    
    
  
  
  • package extras:
    
    
    
    • not gauranteed to be statically defined (TIL)
    
    
    • additional to main dependencies, so not independent
    
    
  
  

Michael #4: livereload

• Example from talkpython.fm: asset_bundler_watcher.py


• The docs are sparse, so see the gist above

Joke:

• A programmer’s partner asks them: “Would you go get a loaf of bread from the store? And if they have eggs, get a dozen.”


• A while later, the programmer returns with 12 loaves of bread and says “They had eggs.”
