I figured it all out, where all the bad code comes from, I know it now!
I think good developers need two things, an ego that makes them wanting to be competent and perceived as such and (very important) a problem with authority!

All the bad code is written by people who wanted to be liked by their teachers. The PM and PO are their teachers now and they make everything possible for them. Technical debt and human costs are swept aside when the authorities want a stupid feature now - because they have to like you and you need to be a nice pet to whip!

Hey, do you have good questions for a junior dev interview? I have things in mind for the interview, but maybe you have something unusual to offer?

People who write functions which return NULL should be moved to /dev/null.

Dear Recruiters on LinkedIn and Co. Would you find it in your hearth to not harass me anymore?

I don't care for your half-assed bullshit job offers and I don't want 5 of them per day, you are not professional.

Leave me alone!

While I writing PHP I have to think of Haskell all the time, how nice everything would be with Haskell and I dream of the time when I can be with Haskell again. <3

Doesn't the existence of NULL in a language mean, that there cannot be a boolean type? Because a bool is defined by the fact, that it can have two possible values. Having NULL changes that.

Without NULL a variable of the type bool could be True or False, two possible values. With NULL is can be True, False or NULL, three possible values.

I hate NULL.

Why is source code so crappy? May career is not the longest, buy in my 8 years I talked to so many developers and every one told me how important quality, standards, tests and architecture are - but every codebase I've seen is lacking all of it. Everything is running on constant live support.

I don't get it. It is like I live in a world where everyone does know what has to be done, but no-one does it. I suspect it is because people are lazy, lying and won't say no but that's also not a world I want to live in.
