INSIGHT

Pandas Adds pd.col Delayed Expressions

Pandas will add pd.col() expressions to represent delayed column expressions evaluated in a DataFrame context.
This replaces many lambda-based column operations and enables clearer, more reliable column expressions.

ADVICE

Use Klein For At-Cost Agentic IDE Tooling

Try Klein to add customizable, client-side agentic AI tooling across IDEs like VS Code and PyCharm.
Give Klein your own OpenAI/Anthropic key so inference billing and data stay under your control.

INSIGHT

Plan-Then-Act Improves Agentic Coding

Klein separates planning and acting, letting the model first produce a plan and then execute smaller steps.
This two-phase approach reduces context size and improves success on complex coding tasks.

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.

Extras

Brian:

Where are the cool kids hosting static sites these days?
- Moving from Netlify to Cloudflare Pages - Will Vincent from Feb 2024
- Traffic is a concern now for even low-ish traffic sites since so many bots are out there
- Netlify free plan is less than 30 GB/mo allowed (grandfathered plans are 100 GB/mo)
- GH Pages have a soft limit of 100 GB/mo
- Cloudflare pages says unlimited

Michael:

PyCon Brazil needs some help with reduced funding from the PSF
- Get a ticket to donate for a student to attend (at the button of the buy ticket checkout dialog)
I upgraded to macOS Tahoe

- Only issue I’ve seen so far has been with alt-tab for macOS

Joke: Hiring in 2025 vs 2021

2021:
- “Do you have an in-house kombucha sommelier?”
- “Let’s talk about pets, are you donkey-friendly?”, “Oh you think this is a joke?”
2025:
- “Round 8/7”
- “Out of 12,000 resumes, the AI picked yours”
- “Binary tree? Build me a foundational model!”
- “Healthcare? What, you want to live forever?”
