Brian #1: djrest2 - A small and simple REST library for Django based on class-based views.

• Emma Levit
• Based on an interesting blog post
  • Why, in 2025, do we still need a 3rd party app to write a REST API with Django?
  • As opposed to using DRF or Django Ninja

Michael #2: Github CLI

• GitHub’s official command line tool
• Features
  • Checking out a pull request locally
  • You can clone any repository using OWNER/REPO syntax: gh repo clone cli/cli
  • Create a pull request interactively: gh pr create
• See all at cli.github.com/manual/examples

Brian #3: caniscrape - Know before you scrape. Analyze any website's anti-bot protections in seconds.

• reddit announcement and discussion

• caniscrape checks a website for common anti-bot mechanisms and reports:

  • A difficulty score (0–10)
  • Which protections are active (e.g., Cloudflare, Akamai, hCaptcha, etc.)
  • What tools you’ll likely need (headless browsers, proxies, CAPTCHA solvers, etc.)
  • Whether using a scraping API might be better

  This helps you decide the right scraping approach before you waste time building a bot that keeps getting blocked.

Michael #4: 🐴 GittyUp

• Never forget to pull again: Automatically discover and update all your Git repositories with one command.
• Built initially to solve this problem
• Rebuilt and published last week as part of my upcoming Agentic AI Programming for Python course. Get notified this week at training.talkpython.fm/getnotified
• Update everything in a folder tree with gittyup
• Review changes, blockers, etc with gittyup --explain

Extras

Brian:

• Three times faster with lazy imports - Hugo van Kemenade
• Interesting discussion on Hugo’s post - on Mastodon
• Use lazy module imports now - Graham Dumpleton
• Graham’s post uses wrapt, a “module for decorators, wrappers and monkey patching”, to simulate lazy imports
• Helpful comment from Adam Johnson on Graham’s post to actually do the import during type checking using if TYPE_CHECKING: import ...

Michael:

• uvloop is back!
• pypi+ listened. :)
