How can learning Rust help make you a better Python Developer? How do techniques required by a compiled language translate to improving your Python code? Christopher Trudeau is back on the show this week with another batch of PyCoder’s Weekly articles and projects.

We discuss a recent article by Bob Belderbos titled “Learning Rust Made Me a Better Python Developer.” Bob has been on a journey learning to program in Rust, which has made him rethink how he’s been writing Python. The compiler forced him to confront things he’d been ignoring.

We also share other articles and projects from the Python community, including recent releases, a boatload of PEPs, NumPy as a synth engine, firing and forgetting with Python’s asyncio, managing state with signals in Python, a documentation site generator for Python packages, and a tool to explain your Python environment.

• Fire and Forget at Textual – In this follow up to a previous article (Fire and forget (or never) with Python’s asyncio, Michael discusses a similar article by Will McGugan as it relates to Textual. He found the problematic pattern in over 500K GitHub files.
• Learning Rust Made Me a Better Python Developer – Bob thinks that learning Rust made him a better Python developer. Not because Rust is better, but because it made him think differently about how he has been writing Python. The compiler forced him to confront things he’d been ignoring.
• Signals: State Management for Python Developers – If you’ve ever debugged why your cache didn’t invalidate or notifications stopped firing after a “simple” state change, this guide is for you. Signals are becoming a JavaScript standard, but Python developers can use the same patterns to eliminate “forgot to update that thing” bugs.

Viktor Glinka: The Curious Product Owner and the Disempowered One — How Scrum Masters Can Help POs Find Their Voice

In this episode, we refer to product owner anti-patterns and product owner interviews on the Scrum Master Toolbox Podcast.

The Great Product Owner: The Curious Negotiator Who Uses Data and Passion

"Great product owners are always asking: what if? How can we do it differently? How can we simplify?" - Viktor Glinka

Viktor describes great product owners as fundamentally curious people who constantly look for simpler, better ways to do things. But curiosity alone isn't enough — they're also skilled negotiators who navigate conversations with teams, stakeholders, and customers. In scaled setups, their work shifts from clarification to prioritization, and they delegate effectively. Viktor highlights their visualization skills with a concrete example: one product owner showed stakeholders a work composition chart revealing that more than 50% of the team's work was technical debt, making it impossible to deliver new features. That single visualization changed the conversation. Great product owners are also systems thinkers who understand dynamics and root causes, avoiding local optimization. Viktor adds something rarely discussed in frameworks: mindfulness. Product owners face constant pressure, and the ability to make peace with decisions — to move forward without regret — is critical. They also share their passion and vulnerability with development teams, telling them personally why they want to build something. It's the emotional complement to data-driven negotiation.

Self-reflection Question: Does your product owner use data and visualization to negotiate with stakeholders, or do they rely on authority and deadlines? How could you help them build those skills?

The Bad Product Owner: The Disempowered Middleman Who Can't Give Direction

"This fear of not being allowed — it's an illusion. You can always do more. Just try. No one will fire you for a suggestion." - Viktor Glinka

For Viktor, the worst product owner anti-pattern isn't about skill or knowledge — it's about empowerment. He believes every person can learn to become a great product owner if they are empowered and trusted by the organization. The red flags are clear: when a product owner talks about deadlines and commitments but never about return on investment or outcomes, that's a sign they're being pushed rather than empowered. Viktor shares the story of a product owner who was struggling to give direction because stakeholders just wanted their features delivered. He was a middleman — afraid to communicate his own vision to the team, afraid to challenge stakeholders. But inside, there was a spark of passion about the product. Viktor helped him uncover it using a simple tool: the product vision canvas. They sat down together and put his thoughts on paper. Once the vision was written, the product owner started thinking about the next step on his own: "What if I show this to stakeholders? What if I tell them there's a better way?" The product vision canvas became the bridge from learned helplessness to ownership.

Self-reflection Question: Is your product owner telling themselves "I'm not allowed to" when they actually could do more? What's the smallest experiment you could run together to test that assumption?

About Jim

Jim Vines grew up in Alabama, but for the past 25 years he has called New York City his home. His lifelong passion for magic was sparked at the age of 12, when a classmate vanished Jim’s milk money.

Jim co-stars in New York City’s #1 family-friendly magic show, the Broadway Magic Hour, now in its second year of performances. Time Out NY rated the show one of the “Best Magic Shows in NYC,” as well as one of the “Best Off Broadway Shows for Kids and Families.”

In 2017 Jim won the title of North American Champion of Close-Up Magic from FISM, the world congress of magic. When Jim recently performed his award-winning act on the hit TV show “Penn & Teller: FOOL US”, the legendary magic duo said, “Just brilliant! We loved every single second of it!”

Jim has shared his magic throughout the US – at such venues as The Wonderground in Las Vegas, the Smoke and Mirrors Theater in Philadelphia, and the Magic Castle in Hollywood – and in 11 other countries around the world.
