We are finally back. Thank you for bearing with us and be prepared for more episodes coming up this year.

This time Johannes Tigges joined me, back in July 2020, to talk about Open Source, Open Source Software and more Open Source $things.

Laufakte (aka Handakte)
"Reference File"
Aktenlage
"state on record" (there does not seem to be an official translation)
Zulieferer
Supplier

UI/UX with Milena Lolli

What is the difference between UI and UX? Should you have one designer doing both or one each? What is UI, and what is UX anyway?

These are just a few questions I discussed with the incredible Milena Lolli.

Last but not least: Sorry for the keyboard and mouse clicks. Milena's boyfriend was working hard during the interview, and we realised too late that the microphone catches that. I promise to improve on that!

"Kotlin" AND ("Manager" OR "CTO" OR "Head of IT" OR "Engineering Lead")

Then we spoke about the pitfalls hidden in data, for example with names. Here is a good article looking at it: https://www.kalzumeus.com/2010/06/17/falsehoods-programmers-believe-about-names/.

Want to dig deeper and look into the mentioned sources? Here are the links:

In episode 3, we dive into full-stack development and what it means to be a full-stack developer. Joining me, in the first interview episode ever on this podcast, is James Mahy. He is doing full-stack development for a long time now, and we talk about how he got there and what benefits it has to understand everything from infrastructure, over backend technologies up to frontend tech. We also talk about his great work on SoSa and why he is building it If you are interested in James' code, have a look at his SoSa GitHub Organisation. And the best way to reach out to him is via LinkedIn Last but definitely not least, a massive shout out to Bradley Parsons. He created the music for my podcast. If you want to learn more about him or want to hire him, have a look at his website: trainsoundstudio.com Errata When James and I discuss the "good old times" with the C64 I use the word Quellcode twice.
