Michael #1: I asked 100 devs why they aren’t shipping faster. Here’s what I learned

• by Daksh Gupta (via PyCoders)
• What’s stopping you from shipping faster?
  • Dependency bugs
  • Complicated codebase
    • >There is so much undocumented in our service, including poor records of new features, nonexistent or outdated info on our dependencies, or even essential things like best practices for testing, a lot of time is wasted in syncs trying to find the right information
• QA Loops
• Waiting for spec
  • > At Amazon? Meetings, approval, talking to 10 different stakeholders because changing the color of a button affects 15 micro services
• Writing tests
• Deployment/build speed
• Scope creep
  • > The human tendency to stuff last-minute items into the crevices of their luggage minutes before leaving for the airport manifests itself at software companies as scope creep.
• Unclear requirements
• Excessive meetings
• Motivation
  • >honest answer is i was on ads
  • >and that’s a very old / complicated / large stack (edited)
  • >and i didn’t understand it
  • >my friends on younger teams seemed happier, i was miserable
• DORA metrics

Brian #2: Python 3.13.0 beta 1 released

• "Python 3.13 is still in development. This release, 3.13.0b1, is the first of four beta release previews of 3.13.”
• New REPL, featuring multi-line editing, color support, colorized exception tracebacks
• Cool GIL, JIT, and GC features
• Typing changes, including typing.TypeIs .
  • See last weeks episode and TypeIs does what I thought TypeGuard would do in Python
• Some nice dead battery removals
• and more
• But seriously, the REPL is cool. Just ask Trey
  • The new REPL in Python 3.13 - Trey Hunner

Michael #3: A theme editor for JupyterLab

• by Florence Haudin
• A new tool for authoring JupyterLab themes
• To lower the bar for customizing JupyterLab we created a new tool providing a simple interface for tuning the JupyterLab appearance interactively.
• See jupyterlab-theme-editor on github

Brian #4: rich-argparse

• “Format argparse and optparse help using rich.”
• “rich-argparse improves the look and readability of argparse's help while requiring minimal changes to the code.”
• They’re not kidding. 2 line code change.

  from rich_argparse import RichHelpFormatter parser = argparse.ArgumentParser(..., formatter_class=RichHelpFormatter) 

Extras

Brian:

• pytest course is now switched to the new platform.
  • I sent out an email including how to save their spot on the old site and mark that spot complete on the new site.
  • There’s now comments on the course now. Trying that out. If you’ve got a question, just ask in that section.

Michael:

• A new Talk Python course: Getting Started with NLP and spaCy
