Ruby with Manuel Meurer

Ruby with Manuel Meurer

You are in for a treat. I got Manuel Meurer from Uplink to speak about his journey with Ruby and Ruby on Rails.
And we had a fantastic conversation with a great look into the good and the not-soo-good-for-Ruby sides of things.

Curious and want to get in touch with Manuel? No worries, check out his website or join us on Uplink via and ping him on Slack

Kotlin with Marcin Moskala

Kotlin with Marcin Moskala

Finally. This is an episode I was really looking forward to. It is all about Kotlin.
The incredible Marcin Moskala joins me to speak about my current programming language of choice.

Marcin is a passionate software developer and entrepreneur. His training platform KtAcademy provides a variety of different courses.
He is also the author of books like Effective Kotlin from which he publishes parts for free on KtAcademy and Twitter.

Alongside our chat about Kotlin we also dive into the topic of technology hypes or "waves" as Marcin puts it.

Open Source Development With Johannes Tigges

Open Source Development With Johannes Tigges

Happy new year!

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.

Johannes and I had some "German moments", meaning we used some German terms and couldn't come up with a proper translation. So, if you are really interested, here is an post-said-translation-attempt:
Laufakte (aka Handakte) "Reference File" Aktenlage "state on record" (there does not seem to be an official translation) Zulieferer Supplier

As always, here are the promised and useful links from/for the episode:

UI/UX with Milena Lolli

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.

To get in touch with Milena, head over to her LinkedIn profile or check out her Twitter feed. Into games? Then her Twitch channel is just for you!

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!

Interested in the mentioned Python podcasts? Check them out here:

Heard about the (probably) XKCD comic? Turns out, it wasn't XKCD (but there is always a high chance it is). BUT, being a data scientist, Andreas found it anyways. Here you go

Then we spoke about the pitfalls hidden in data, for example with names. Here is a good article looking at it:

Little errata:

  • The first iPhone was released in 2007 and not in 2009. We got this wrong somehow, sorry.

From Backends and Frontends

From Backends and Frontends

We talk a lot about frontends and backends, but what are these things actually?

Using the example of an online food order service, I try to explain exactly that and give a small overview of different languages and tech stacks each of them can be implemented in.

What is your take on it? Did I miss something? Let me know!

A short introduction

A short introduction

I love tech, I love coding and I love sharing knowledge. So the question was: Why don't I have my own podcast? 

Well, this changes now. I will share my knowledge about tech, coding, freelancing and all the other things related with you on here and will bring interesting interviews with people I highly respect and trust. 

So stay tuned, give feedback and always keep on coding.
