Design Mode. Do you know what the observer mode is?

If you don't know, I suggest you go here and try again. After reading this, you may be surprised by the fact that the software migrant workers know about event registration.

Yes, the experts often jump out of these high-end words, and the people who listen to them are often in the fog and gradually become self-explanatory. Wow... it's really amazing to speak.

The plan should also be regarded as a model. The enemy is at the moment, and Saddam says let's make an empty city plan! As a result, we all know that his old man has been on trial recently.

The mode is not used for application, but for reference.

The people who invented the patterns did not know that there were patterns in the world. They knew that they would make the best choice by using the various information at hand. later, their successful experiences were promoted as models. when someone else uses a lawn boat to borrow an arrow, if you follow it, it may become a hedgehog.

Do not regard patterns as the Bible. There are more solutions that may not be available in the book. They may be more effective for actual problems. You can also create patterns, but do not blow them into patterns.

Patterns are others' experiences and routines. if you are practicing martial arts, the mode can only be regarded as a basic effort. in addition, the same mode may have different names in different schools. If you blindly learn the tricks of different schools and do not notice the following kill methods, it is better to learn Oracle/Unix.

The mode can only be used as a syntax. Do you hate the syntax? The Chinese Syntax is not good. You can write poems, write love letters, and repeat online. The real experts do not play cards in mode.

The pattern is a nerd, and the pattern is not a donkey. Let others list several pattern people may be graduated from IBM.
