Android Developer Live Q&A #39 – Clean Architecture, Kotlin, Java, TDD

Welcome to my livestream Q&A. It’s live, and it works best when you ask questions. I mostly do this for beginners (although I’m happy to chat about advanced topics with more senior devs), so if you’re a beginner, ASK SOME DAMN QUESTIONS.

UPDATE – one year after visiting North Korea I traveled to South Korea and made a video comparing my experiences in both of these two countries. Watch it here:

I’ve always been very interested in North Korea because it seemed to be one of the most unique and mysterious countries in the whole world. This is my day to day life throughout the 7 days that I spent in North Korea. You can never be sure whether things were staged or not in North Korea because you are only shown what they want you to see. You can’t choose where or when you will be going to specific places, they simply tell you to hop on a bus and ask you to get off at one point or another.

That is why I didn’t want to offer my opinion about whether things were staged or not, whether they were good or not, or honest or not. My goal was to show you what my day to day life looked like when I was there and let you make up your own mind and judge for yourself.

Do not judge North Korea only from what you see in this video. This is what they showed us and there’s a reason they show some things and not show the others. Also, knowing how much control they exercise over the population, everything could have been staged only for us.

My favorite books about North Korea:

Dear Leader by Jang Jin Sung –;
Escape From Camp 14 by Blaine Harden –;
Nothing To Envy by Barbara Demick –;
1984 by George Orwell (I couldn’t believe how similar some things in North Korea looked to the ones in the book) –
