# Devs vs. Marketers, COBOL and Copilot, Make Live Coding Easy and more - The Best of LIVE 2025 - Part 3

**By:** [Daniel Cranney](https://www.wearedevelopers.com/@daniel-cranney)

**Published:** December 31, 2025

In this, the third and final part of our series looking back on the best bits from the Weekly Developer Show, we dig into some more classic moments from our guests for you to enjoy.

[Raphael De Lio](https://nl.linkedin.com/in/raphaeldelio) reminds us that contributing to open source - and sharing your work - can be an amazing way to land a job in tech.

[Tim Cadenbach](https://de.linkedin.com/in/timcadenbach) delivered a wonderfully direct message:  
**marketers are not developers** — and pretending otherwise helps no one.

[Julie Kordick](https://de.linkedin.com/in/julia-kordick) shared how her team migrated legacy COBOL systems into the cloud using Microsoft Copilot.

[Jan Moser](https://ch.linkedin.com/in/moserjan) drew beautiful parallels between tattooing and software.

[Elio Struyf](https://be.linkedin.com/in/estruyf) showed how tools like DemoTime help make live coding stress-free (or pretty close to it).

[Johanna Pirker](https://www.linkedin.com/in/johannapirker/) explored how AI is reshaping game development, from world‑building to storytelling, and even cheating.

[Marc Duiker](https://www.linkedin.com/in/mduiker) said that while vibe coding can be fun and shipping is great, shipping responsibly is better.

[Raymond Camden](https://www.linkedin.com/in/raymondcamden) showed us all how easy it can be to build your own AI summariser.
