Pragmatic functional refactoring with java 8 (1)RichardWarburton
You may be hearing a lot of buzz around functional programming. For example, Java 8 recently introduced new features (lambda expressions and method references) and APIs (Streams, Optional and CompletableFutures) inspired from functional ideas such as first-class functions, composition and immutability.
However, what does this mean for my existing codebase?
In this talk we show how you can refactor your traditional object-oriented Java to using FP features and APIs from Java 8 in a beneficial manner.
We will discuss:
* How to adapt to requirement changes using first-class functions
* How you can enhance code reusability using currying
* How you can make your code more robust by favouring immutability over mutability
* How you can design better APIs and reduce unintended null pointer exceptions using an optional data type
Julia programming language is a high-level, high-performance dynamic programming language for technical computing. It can be applied for Data Science, Machine Learning tasks, the web, among others. These slides are a brief introduction to this amazing language that facilitates my daily activities as Data Science and Software Engineer.

Kotlin Developer Starter in Android - STX Next Lightning Talks - Feb 12, 2016STX Next
Kotlin - one of the popular programming languages built on top of Java that runs on JVM. Thanks to JetBrains support and excellent IDE integration, it’s an ideal choice for Android development. 100% Java compatibility, interoperability and no runtime overhead is just the beginning of a long list of strengths. Kotlin is supposed to be a subset of SCALA, on one hand covering major advantages for developers and keeping short compile times on the other.
This presentation is a Developer Starter - a set of hand-picked information allowing a person with no knowledge of Kotlin to start writing basic Android activities and set up a kotlin-based Android project. It starts with language background, reasons for its creation and advantages. Then presents basic use cases, syntax, structures and patterns. Later on Kotlin is presented in Android context. Simple project structure, imports and Kotlin usage with Android SDK is explained. In the end cost of Kotlin compilation is presented and the language is compared to SCALA and SWIFT.

Neuro-symbolic is not enough, we need neuro-*semantic*Frank van Harmelen
Neuro-symbolic (NeSy) AI is on the rise. However, simply machine learning on just any symbolic structure is not sufficient to really harvest the gains of NeSy. These will only be gained when the symbolic structures have an actual semantics. I give an operational definition of semantics as “predictable inference”.
All of this illustrated with link prediction over knowledge graphs, but the argument is general.

2. Data Members
Types of data member :
Constant data members.
Mutable data members.
Static data members.
3. Member Functions
Different types of member functions:
Nested Member functions.
Overloaded member functions.
Constant member function.
Member functions with default arguments.
Inline member functions.
Static member functions.
4. Constant data members
The data members whose value cannot be
changed throughout the execution of the
program.
They are declared by preceding the qualifier
const.
Example:
const int x = 10;
6. Mutable data members
If the need arises such that the constant
member functions has to modify the value of
the data members then the data member has
to be declared by prefixing the keyword
„mutable‟.
7. Example:
#include<iostream>
class x
{
int a ;
mutable int b;
public:
void xyz() const
{
a++; // error
b++; // legal
}
};
void main()
{
X x2;
X2.xyz();
}
8. Constant member function
#include<iostream.h>
void main()
class x
{
{ x x1;
x1.getdata(56);
int a;
Cout<< x1.setdata()<<endl;
public: }
void getdata(int x)
{
a=x;
}
int setdata() const
{
a++; // error
return a;
}
};
9. Static data member
Those members whose members are
accessed by all the objects of a class.
It is not own by any object of a class.
Only one copy of a static data member is
created for a class which can be accessed by
all the objects of that class.
10. Example:
#include<iostream.h>
class x void main()
{
{ x x1,x2;
static int a; x1.display();
x2.display();
int b; x1.getdata(1);
x2.getdata(2);
public: x1.display();
x2.display();
void getdata(int x) }
{
Output:
0
b=x; 0
a++; 2
2
}
void display(void)
{
cout<< a<< endl;
}
};
int x :: a;
11. Static member function
#include<iostream.h>
void main()
class sample
{
{ sample s1,s2;
Sample :: getdata(1)//invoking static member function
static int a;
s1.display();
s2.getdata(2);// invoking static member function using object
s2.display();
public: }
Output:
1
Static void getdata(int x)
2
{
a=x;
}
void display(void)
{
cout<< a<< endl;
}
};
Int sample :: a;
12. Nested member function
#include<iostream>
void main()
class sample {
{ sample e;
t =e.get_data (34);
int x; cout<< t << endl;
public: }
Output:
void get_data(int); Nested member function
void message(char *); 34
};
int sample :: get_data(int a)
{
x=a;
message(“Nested member function”);
return x;
}
void sample :: message(char *s)
{
cout<< s<< endl;
}
13. Overloaded member function
With single class:
Class A
{ Void main()
Public: {
A a1;
void display(void); a1.display(void);
void display(int); a1.display(20);
}
}; Output:
void a :: display(void) Hello
{ 20
cout<< “Hello”<< endl;
}
void a :: display(int d)
{
cout<<d<< endl;
}
14. Overloaded member function
Two different classes.
Class A Void main()
{ {
A a1;
Public:
B b1;
void display(void); a1.display(void);
}; b1.display(void);
Class B }
Output:
{ Hello
Public: World
void display(void);
};
void A :: display(void)
{
cout<< “Hello”<< endl;
}
void B :: display(void)
{
cout<<“World”<< endl;
}
15. Member functions with default
arguments
#include<iostream>
class addition
{
Public:
void add(int, int = 2);
};
void addition :: add(int a, int b)
{
return(a+b);
}
Void main()
{
addition a;
a.add(5,6);
a.add(6);
}
Output
11
8
16. Inline function
Class test
{
void main()
private :
{
int a; test t;
int b; int a,b;
public: cout<<“enter the two numbers” <<
endl;
void set_data(int , int )
cin>> a >> b;
int big() // t.set_data(a,b);
automatic inline function cout<<“the largest number is ” <<
{ t.big() << endl;
if (a > b) }
return a;
else
return b;
}
};
inline void test :: set_data(int x, int y)
{
a=x;
b=y;
}
17. Friend function
To provide non-member function to access
private data member of a class, c++ allow the
non-member to be made friend of that class.
Syntax:
friend<data_type> <func_name>();
18. Example
Friend non-member function:
Class sample
{
Int a;
Public:
Friend void change(sample &);
};
Void change(sample &x)
{
x.a= 5;
}
Void main()
{
Sample A;
Change(A);
}
19. Example
Friend member function:
Void test :: set_data(sample &a, int b)
Class sample; // forward declaration. {
Class test a.x= b;
}
{ Int sample :: get_data(void)
Public: {
Return x;
Void set_data(sample &, int); }
}; Void main()
{
Class sample Sample e;
{ Test f;
f.set_data(5);
Private: Cout<< e.get_data()<< endl;
Int x; }
Public:
Int get_data(void);
Friend void test :: set_data(sample &, int);
};
20. Friend class
A class is made friend of another class. For
example,
If a class X is a friend of class Y then all the
member function of class X can access the
private data member of class Y.
Declaration:
friend class X;
21. Example of friend class
# include<iostream>
Class Y; void Y :: change_data(X &c, int p, int
q)
Class X {
{ c.X = p;
c.Y = q;
Int x,y;
}
Public: void X :: show_data()
Void show_data(); {
Cout<< x << y << endl;
friend class Y; }
}; Int main()
{
Class Y X x1;
{ Y y1;
Y1.change_data(x1,5,6);
Public:
x1.show_data();
void change_data( X &, int, int); return 0;
}; }
22. Array of class objects
Array of class objects is similar to the array of
structures.
Syntax:
Class <class_name>
{
// class body
};
<class_name><object_name[size]>;
25. By value
Here only the copy of the object is passed to the
function definition.
The modification on objects made in the called
function will not be reflected in the calling
function.
26. By reference
Here when the object is passed to the function
definition, the formal argument shares the
memory location of the actual arguments.
Hence the modification on objects made in the
called function will be reflected in the calling
function.
27. By pointer
Here pointer to the object is passed. The
member of the objects passed are accessed
by the arrow operator(->).
The modification on objects made in the called
function will be reflected in the calling function.
28. Example
#include<iostream> void set(A *z,int t)
{
class A z->a = t;
{ }
int a; int main()
public: {
A a1;
void set(A, int); // call by value a1.a = 10;
void set(int, A &); // call by reference cout<<a;
a1.set(a1,5);// by value
void set(A *, int); // call by pointer
cout<<a;
}; a1.set(20,a1);// by reference
cout<<a;
void set(A x,int p)
a1.set(&a1,30);// by pointer
{ cout<<a;
}
x.a = p;
} Output:
10
void set(int q, A &y)
10
{ 20
30
y.a = q;
}
29. Nested class
Class within a class
Example:
class A
{
// class body
class B
{
// inner class body
};
}
