Evry one have personal workshop. Everything what is part of them.

1. Programming Style
Design Patterns +
Library +
Community =
Framework

2. Introduction
Conceptions

3. You can not be an individualist

4. Code Style
● camelCase
getName, setName, init, ....
● PascalCase (UpperCamelCase)
GetName, SetName, Init, ....
● Hungarian Notation
bBusy, chInitial, fnFunction, ...

5. Design Patterns
Golden Rules

6. DRY
In software engineering, Don't Repeat
Yourself (DRY) or Duplication is Evil (DIE) is a
principle of software development

7. DRY (Programmers Story #1)
Hi.
I am Tom. I am writing my backend with PHP
and frontend with html5 and JS. Now I am
writing forms of my web shop. I am writing
frontend validator with js and backend
validation with php....
//Say no to Tom

8. KISS
KISS is an acronym for the design principle
"Keep it simple, Stupid!".

9. KISS (fuck logic #1)
#define true false
if(true==false){
cout<<"OK";
}else{
cout<<"NO";
}

10. KISS (fuck logic #2)
try {
return true;
} finally {
return false;
}
//Return??

11. KISS (fuck logic #3)
<?php
var_dump(NULL < -50); // TRUE
var_dump(NULL < 0); // FALSE
var_dump(FALSE < TRUE); // TRUE
var_dump(FALSE < FALSE); // FALSE

12. Design Patterns
OOP

13. SOLID
The principles when applied together intends
to make it more likely that a programmer will
create a system that is easy to maintain and
extend over time.
PS. SOLID (Single responsibility, Open-closed,
Liskov substitution, Interface segregation and
Dependency inversion) - WTF Name??

14. SRP (Single responsibility principle)
class RestaurantAndFirstShopOnTheLeft {
//Restaurant
int waiter_age;
char[] waiter_name;
float pizzaCost;
//Shop
float itemsCost;
}

15. OCP (Open/closed principle)
“software entities … should be open for
extension, but closed for modification”.
final class HashMap{...} //??
final class ArrayList{...} //??
final public getItem(...){...} //??

16. LSP (Liskov substitution principle)
“objects in a program should be replaceable
with instances of their subtypes without
altering the correctness of that program”
Object o = new ArrayList();

17. ISP (Interface segregation principle)
“many client-specific interfaces are better
than one general-purpose interface.”
class Restaurant : Building {
//...
}

18. DIP (Dependency inversion principle)
@Stateless
class Users{
@PersistenceContext
private EntityManager entityManager;
//...
}

19. Design Patterns
Application

20. MVC
Model–view–controller (MVC) is a software
architecture pattern which separates the
representation of information from the user's
interaction with it.

21. MVC Example: ZendFramework

22. MVP (First View)
Model–view–presenter (MVP) is a derivative of
the model–view–controller (MVC) software
pattern, also used mostly for building user
interfaces.

23. MVP Example - Java Server Face

24. MVP - form
<h:form>
<h:outputText value="Enter your name: " /></td>
<h:inputText value="#{StoreNameBean.personName}" />
<h:commandButton action="result" value="Say Hello" />
</h:form>

25. Library
Overview

26. Library
A collection of standard programs and
subroutines that are stored and available for
immediate use.

27. Library - Examples:
● C++ (Standard Template Library)
● OGRE
● jQuery
● Allegro
and many more...

28. Library Or Framework
But my ankle use ZendFramework
as Library...
Do you think Java Platform API is a library??
