Everything you need to know about development
Trends in programming change almost every month. One language reaches the top, others settle in computer science textbooks. The main fear of a developer is to understand that he has fallen italy email list behind progress and has long since given way to a new generation.

In fact, programming is the same as love. The same laws are in effect for years, and no others appear. When you know the basics, you don’t need to adapt to new ideas and trends. Here are three basic principles, knowing which, a developer will definitely not get lost!

DRY — don't repeat yourself
Most developers know this principle under the acronym DRY. It first appeared in the book "The Pragmatic Programmer", although the idea itself has been around for a long time.

Let's say a developer has been given a task to create a serious, organized project from scratch. Even experienced programmers have a hard time managing complex systems. It's easier for a person to come up with a new solution to a known problem than to complete a huge project. The best choice is to break a labor-intensive task into smaller parts.
