Traditional Education – Still the Way to Go?

By |2019-12-30T19:39:16+00:00December 30th, 2019|Everyday Life, Lifestyle, Programming, Software development|0 Comments

A friend of mine, who's a mechanical engineer, plans to become an iOS developer. He was looking for "the best college" that would prepare him for the career switch. When I told him he could learn all the necessary skills online, he looked at me like I had two heads. Some may still think that attending a college is the only way to become successful. In this rapidly changing world, this couldn't be further from the truth. More often than not, all we get from conventional education is overpriced, stale content. Online teaching platforms provide up-to-date classes for a [...]

A property wrapper lets us define property access patterns that can be applied repeatedly. What does that mean? In essence, the property wrapper is a data structure that provides controlled access to the property that uses it as a wrapper. In this article, I show you how to define a property wrapper and how to apply it. I'm also going to show you a practical example of using property wrappers. Alright, let's dig in!

How to Avoid Overworking Yourself to Death

By |2019-12-13T19:51:03+00:00December 13th, 2019|entrepreneurship, Everyday Life, Lifestyle|0 Comments

Death from overwork is so common in Japan, they even have a word for it: "karoshi." If you keep overworking yourself, you'll get into trouble with health. You might end up spending the extra money you earned on hospital bills. "Mens sana in corpore sano" - an ancient, Latin phrase, that means "a healthy mind in a healthy body." If we keep our body fit, it's going to also improve our mind. It's just as simple as that. So, decline all the after-5:00 pm meetings.

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.
