Brian #1: pandas is getting pd.col expressions

• Marco Gorelli
• Next release of Pandas will have pd.col(), inspired by some of the other frameworks
  • I’m guessing Pandas 2.3.3? or 2.4.0? or 3.0.0? (depending on which version they bump?)
• “The output of pd.col is called an expression. You can think of it as a delayed column - it only produces a result once it's evaluated inside a dataframe context.”
• It replaces many contexts where lambda expressions were used

Michael #2: Cline, At-Cost Agentic IDE Tooling

• Free and open-source
• Probably supports your IDE (if your IDE isn’t a terminal)
  • VS Code
  • VS Code Insiders
  • Cursor
  • Windsurf
  • JetBrains IDEs (including PyCharm)
• You pick plan or act (very important)
• It shows you the price as the AI works, per request, right in the UI

Brian #3: uv cheatsheet

• Rodgrigo at mathspp.com
• Nice compact cheat sheet of commands for
  • Creating projects
  • Managing dependencies
  • Lifecycle stuff like build, publish, bumping version
  • uv tool (uvx) commands
  • working with scripts
  • Installing and updating Python versions
  • plus venv, pip, format, help and update

Michael #4: Ducky Network UI

• Ducky is a powerful, open-source, all-in-one desktop application built with Python and PySide6.
• It is designed to be the perfect companion for network engineers, students, and tech enthusiasts, combining several essential utilities into a single, intuitive graphical interface.
• Features
  • Multi-Protocol Terminal: Connect via SSH, Telnet, and Serial (COM) in a modern, tabbed interface.
  • SNMP Topology Mapper: Automatically discover your network with a ping and SNMP sweep. See a graphical map of your devices, color-coded by type, and click to view detailed information.
  • Network Diagnostics: A full suite of tools including a Subnet Calculator, Network Monitor (Ping, Traceroute), and a multi-threaded Port Scanner.
  • Security Toolkit: Look up CVEs from the NIST database, check password strength, and calculate file hashes (MD5, SHA1, SHA256, SHA512).
  • Rich-Text Notepad: Keep notes and reminders in a dockable widget with formatting tools and auto-save.
  • Customizable UI: Switch between a sleek dark theme and a clean light theme. Customize terminal colors and fonts to your liking.

  • “Binary tree? Build me a foundational model!”
  • “Healthcare? What, you want to live forever?”
