"Hi, Amigo!" "Hi, Bilaabo!" "Today I'm going to tell you about how programs are usually developed." "In the 20th century, when modern IT was in its infancy, everyone seemed to think that programming was like construction or manufacturing." "Things usually went something like this:" "The customer would explain the type of program that he needed — what it should do and how it should do it ..."

"So, I want to tell you about Agile and Scrum." "At the beginning of the 21st century, the way people thought about programing was turned upside down." "Everyone was convinced that long-term planning wasn't working, so they decided to abandon it altogether." "How did they do that?" "Here's how." "They invented the most flexible project management approach possible ..."

I'm ready ..."

"As you probably already know, annotations are special words that can be put next to classes, fields, methods, and variables." "Yes. I encounter them very frequently." "Sometimes they're also called metadata. Their primary purpose is to store specific additional information about methods, fields, and classes ..."

"Now let's create and use a couple of annotations." "For example, let's say we're writing a game engine. Our game has a lot of characters that fall into three categories: elves, palace guards, and villains." "As the game is developed, new characters may be added, and this will alter the game balance. Thus, it would be very convenient to assign each 'character class' its own annotation that describes its physical characteristics ..."
