There should be a TV show where junior programmers make a software and then one famous senior programmer finds bugs, yell at them and fixes it. The name of the show will be "Coding nightmares".

A better way to software testing - 'Test your assumptions first'

Best: gaining experience and learning new ways to write programs in the best way possible, even beyond working hours

Worst: the amount of ABAP code I saw these past two years gives me nightmares, and older programmers don't seem to want to improve and advance from the old ways of the language 😥
