How I Lost 10 Years of My Life – Don’t Make the Same Terrible Mistake!

By |2019-10-24T18:20:13+00:00October 24th, 2019|entrepreneurship, Everyday Life, Lifestyle|0 Comments

I had to spend almost two decades in the corporate world to realize that I never wanted anything but work for myself. Luckily, all those long years of apprenticeship were not useless. (Well, except for the last ten or so, when I worked with the most unprofessional "managers" ever.) Bottom line: I gained enough expertise and capital to start my own business.

Being Smart vs. Being **Really** Smart

By |2019-08-28T21:02:07+00:00August 28th, 2019|Uncategorized|0 Comments

I speak five languages, and I can program a computer in about a dozen programming languages. However, it took me almost two decades to realize that I can work on my own, without being trapped in any "company culture." It's been 18 years that are gone forever, and I'll never have again. My only hope is that my kids will outsmart me.

Imprisoned By Our Own “Success”

By |2019-08-02T20:57:25+00:00August 2nd, 2019|Uncategorized|0 Comments

Freedom and enjoying life - while we still can - is more important than scaling our business or climbing the corporate ladder. Too many of us get trapped by our own "success" and forget to live a life that's worth living. Meet old friends. Go out, enjoy nature. Ride a bike. Visit your parents. Forget about office politics, money, appointments, and checking your phone every ten seconds. Life begins when you leave all of that shit behind you!

Can Arrows Cause Cognitive Overload?

By |2019-07-29T16:23:28+00:00July 29th, 2019|clean code, Programming, Software development|0 Comments

In programming, deep nesting is a problem known as the Arrow Anti-Pattern. The name comes from the shape of nested if statements: if ...:     if ...:         if ...             if ...                 if ...                     # code                 else:             else:         else:     else: else: Normally, you shouldn’t go beyond two levels of nesting. Otherwise, your code becomes overly complex and hard to understand. Boolean operators allow us to combine multiple conditional expressions without relying on nested if statements. I talk about the Arrow Anti-pattern and further, programming related topics in my recently published book The Non-Programmer's Programming Book: Programming Foundations for Absolute Beginners. Learn to [...]

SCRUM: Framework or Methodology?

By |2019-07-29T16:08:30+00:00July 29th, 2019|Agile, Scrum, Software development|0 Comments

Per definition, Scrum is an Agile framework. Some see it as a methodology, though. Now, who’s right? It really depends on how you look at it. First, let’s try to clarify the difference between framework and methodology. In this context, a framework is a loose guideline, that defines the main structure of software development. However, it doesn’t dictate how to do certain things. A framework is not a step-by-step recipe, in that it doesn’t tell us what tools and processes to rely on. Given a framework, we can define the way we want to achieve our goals. Now we’ve [...]
