Upload an animated gif file in blog

 I download a free trial version from gif-animator.com
http://www.gif-animator.com/download.html
I produced following animated gif:




Wait, the ball is not animated.  This is because: if you upload the animated image direct via the Blogger photo upload icon Google Blogger photo upload icon, the image will no longer be animated.


I need to upload my animated gif to the free Photobucket image host and it give you 4 codes. The second one is the actual URL and if you are familiar with HTML for displaying images, you can type the HTML yourself. It will be of the form
<img scr="photo URL" alt="some text" title="some text" / >


Replace 'photo URL' with the actual URL of the photo which you can get by clicking on the second box (Direct Link) . Now I can see the animated one below.

plot and embed dynamic stock chart using amcharts



1) amcharts can be downloaded from http://amcharts.com/download
I only download stock. The FAQ can be found http://amcharts.com/docs/v.1/stock
2). For beginner, only three files are most important.
amstock.swf, data.csv, amstock_settings.xml


3) I download Canada S&P/TSX csv file from
http://finance.yahoo.com/q/hp?s=^GSPTSE&a=00&b=3&c=2000&d=08&e=20&f=2010&g=d
and save it as data.csv. In amstock_settings.xml, replace date, volume close
using following, which are the data format from download.


<columns>
   <column>date</column>

   <column>open</column>
   <column>high</column>
   <column>low</column>

   <column>close</column>
   <column>volume</column>
</columns>

I change the title in amstock_settings.xml as Canada S&P/TSX
4) I simply display amstock.swf in my web server.
Below is the results, you can select any time range, the same as yahoo financial.

Embed stock index in your blog using goolge finance

1. One simple way is to embed image, Example Canada S&P/TSX
image source (changed real time when reloaded):
src="http://chart.finance.yahoo.com/z?s=%5EGSPTSE&t=1d&q=l&l=on&z=l&p=s&a=v&p=s&lang=en-US&region=US"

2. Go to Google finance, go to
http://www.google.com/finance?q=TSE%3A.GSPTSE
click link to this chart, copy the code, still need to think of how to get off
things other than the chart

C++ interview questions (5) -Algorithm



C++ interview Questions (1)
C++ interview Questions (2)
C++ interview questions (3)
C++ interview questions(4)


26.Describe hash table  and one simple rehashing policy.
A hash table or hash map is a data structure that uses a hash function to map identifying values, known as keys (e.g., a person's name), to their associated values (e.g., their telephone number)

The implementation of this calculation is the hash function f:
index = f(key, arrayLength)
The hash function calculates an index within the array from the data key. arrayLength is the size of the array.

The simplest rehashing policy is linear probing. Suppose a key K hashes to location i. Suppose other key occupies H[i]. The following function is used to generate alternative locations:

rehash(j) = (j + 1) mod n
where j is the location most recently probed and n the size of the hash table. Initially j = i, the hash code for K. Notice that this version of rehash does not depend on K.

Linear probing is a scheme in for resolving hash collisions of values of hash functions by sequentially searching the hash table for a free location.[1]
newLocation = (startingValue + stepSize) % arraySize


The first source code is an implementation of a Hash Map with open addressing (linear probing) as collision resolution method.
// hashMapLinear[] is the hash map
void linearProbingInsert(int value){
    int probe = hash(value);
    while (hashMapLinear[probe]!=0){                            
        probe = fmod((probe+1),SIZE_HASH_MAP); 
    }
    hashMapLinear[probe] = value; 
}
 
int linearProbingSearch(int value){
    int probe = hash(value);  
    int i;
    for(i=0;i<size_hash_map ;i++){     
        if(hashMapLinear[probe]==value)
            return TRUE;                             
        probe = fmod((probe+1),SIZE_HASH_MAP);               
    }
    return FALSE;                                           
}

27. Describe Stacks and name a couple of places where stacks are useful. 
 A stack is a last in, first out (LIFO) abstract data type and data structure. A stack can have any abstract data type as an element, but is characterized by only two fundamental operations: push and pop. Many virtual machines are also stack-oriented, including the p-code machine and the Java Virtual Machine.


Below is example to  to use stacks to check an input file for parentheses matches.
Algorithm: Read from input file, process on character, push , i.e ++ptr if "(",  pop, i.e. --ptr  if ")",   the parentheses missing when ptr < 0

--------------------------------------------------------------------
#include <fstream.h>
#include <stdlib.h>   // for exit(..)
#include <stdio.h>
#include "stack.h"

int main()
{
   char c;
   int k;
ifstream f;
  f.open( "input.txt" );

  if( ! f ){
    cout << "Error opening file. Quitting.\n";
    exit(-1);
  }

   //initialize

   stk_init();
      c = getchar();
      putchar(c);

   // loop through file one char at a time
   while (c!=EOF)
   {
     // process one character
     // push (,  pop if ),
     // check stack empty if \n,
     // ignore others
     // if error, move to next line
       if (c == '(')
       {
         stk_push(c);

       }
       else if (c == ')')
       {
            if (c !== '\n')    
            stk_pop(c);
            else if (c == '(')
            stk_push (c);
// pop stack, if empty have missing (
       }
       else if (c == '\n')
       {
         // check on missing )
         // set up for next line
         stk_init();
       }
       if (stk_error()) //skip rest of line

       else // get next char
       {
       }
     } // endwhile
   return 0;
}

stach.h as below:
#define STK_ERROR '?' 
/* Private data: */
#define MAX 50 
static int error;   /* error flag */
static char data[MAX];   /* the stack */
static int ptr;         /* stack pointer */

/* Function implementation */

void stk_init() {
   ptr = 0;
   error = 0;
}

void stk_push(char x) {
    if (ptr < MAX) {
        data[ptr++] = x;
        error = 0;
    }
    else
        error = 1;
}

char stk_pop(void) {
    if (ptr > 0) {
        int x = data[--ptr];
        error = 0;
        return x;
    } else {
        error = 1;
        return STK_ERROR;
    }
}

char stk_top(void) {
    if (ptr > 0) {
        error = 0;
        return data[ptr-1];
    } else {
        error = 1;
        return STK_ERROR;
    }
}

int stk_size(void) {
    return ptr;
}

int stk_error(void) {
    return error;
}

Large File Support in Linux for C/C++ operations

In a C/C++ application the file operations can be handled using the fcntl.h header file.


It provides operations for opening, writing to a file and many more. The size of every file is stored in a variable of type off_t. For 32-bit systems the maximum value for off_t is 231 thus limiting the maximal file size to 231 bytes (2 GiB). For 64 bit systems like x86-64 this maximum value is much greater and they have support for large files with size up to 263 bytes.

Python interview questions (2)

Python interview question (1)

8. What is self in python?
The first argument of every class method, including __init__, is always a reference to the current instance of the class. By convention, this argument is always named self. In the __init__ method, self refers to the newly created object; in other class methods, it refers to the instance whose method was called. Although you need to specify self explicitly when defining the method, you do not specify it when calling the method; Python will add it for you automatically.


For example:
>>> class Complex:
...     def __init__(self, realpart, imagpart):
...         self.r = realpart
...         self.i = imagpart
...
>>> x = Complex(3.0, -4.5)
>>> x.r, x.i
(3.0, -4.5) 
 
9. What is class and method?
 
 Class objects are used as  templates to create
 instance objects, which embody both   data 
  and methods. Methods are defined as functions inside
  the class definition.



class BaseClass:
    # This data will exist in all
    # BaseClasses (even uninstantiated ones)
    Name = "BaseClass"
    # __init__ is a class constructor
    # __****__ is usually a special class method.
    def __init__(self, arg1, arg2):
        # These values are created
        # when the class is instantiated.
        self.value1 = arg1
        self.value2 = arg2

    # Self is used as an argument to
    # pretty much all class functions.
    # However, you do NOT need to pass
    # the argument self if you call this method
    # from a Class, because the class provides
    # the value of itself.
    def display(self):
        print self.Name
        print self.value1
        print self.value2

        
 10. How do I make a Python script executable on Unix? 

You need to do two things: the script file's mode must 
be executable and the first line must begin with #! 
followed by the path of the Python interpreter. 

The first is done by executing chmod +x scriptfile or 
perhaps chmod 755 scriptfile. 

The second can be done in a number of ways. The most 
straightforward way is to write 

#!/usr/local/bin/python 

as the very first line of your file, using the pathname 
for where the Python interpreter is installed on your 
platform. 

If you would like the script to be independent of where 
the Python interpreter lives, you can use the "env" 
program. Almost all Unix variants support the following, 
assuming the python interpreter is in a directory on the 
user's $PATH: 

#! /usr/bin/env python 

python interview questions (1)

   Think in python, a nice online python book.


1. What is Python?
Python is an interpreted, interactive, object-oriented programming language. It incorporates modules, exceptions, dynamic typing, very high level dynamic data types, and classes.


2.  How can I find the methods or attributes of an object?
For an instance x of a user-defined class, dir(x) returns an alphabetized list of the names containing the instance attributes and methods and attributes defined by its class.

3. How do I convert a string to a number?
For integers, use the built-in int() type constructor, e.g. int('144') == 144. Similarly, float() converts to floating-point, e.g. float('144') == 144.0. The number 144 to the string '144', use the built-in function str().

4. What is tuple and list? How to convert between tuple and list?
A tuple is a sequence of values. The values can be any type, and they are indexed by integers, so in that respect tuples are a lot like lists. The important difference is that tuples are immutable.

Like a string, a list is a sequence of values. In a string, the values are characters; in a list, they can be any type. The values in a list are called elements or sometimes items. The list is mutable.

A dictionary is like a list, but more general. In a list, the indices have to be integers; in a dictionary they can be (almost) any type.

The function tuple(seq) converts any sequence (actually, any iterable) into a tuple. The function list(seq) converts any sequence or iterable into a list with the same items in the same order.  

5. What is numpy and scipy?
numpy is a python extension module to support efficient operation on arrays of homogeneous data.


SciPy is a set of Open Source scientific and numeric tools for Python. It currently supports special functions, integration, ordinary differential equation (ODE) solvers, gradient optimization, parallel programming tools, an expression-to-C++ compiler for fast execution, and others.

6.What scientific libraries are available in SciPy?

The full SciPy also has the following modules:
cluster
information theory functions (currently, vq and kmeans)
fftpack
fast Fourier transform module based on fftpack and fftw when available
integrate
numeric integration for bounded and unbounded ranges. ODE solvers.
interpolate
interpolation of values from a sample data set.
io
reading and writing numeric arrays, MATLAB .mat, and Matrix Market .mtx files
lib
access to the BLAS and LAPACK libraries
linalg
linear algebra and BLAS routines based on the ATLAS implementation of LAPACK
maxentropy
Support for fitting maximum entropy models, either discrete or continuous
misc
other routines that don't clearly fit anywhere else. The Python Image Library (PIL) interface is located here.
optimize
constrained and unconstrained optimization methods and root-finding algorithms
signal
signal processing (1-D and 2-D filtering, filter design, LTI systems, etc.)
sparse
Some sparse matrix support. LU factorization and solving Sparse linear systems
special
special function types (bessel, gamma, airy, etc.)
stats
statistical functions (stdev, var, mean, etc.)
weave
compilation of numeric expressions to C++ for fast execution
6. How to load an array from a text file in pyhton?

Use numpy.loadtxt. Even if your text file has header and footer lines or comments, loadtxt can almost certainly read it; it is convenient and efficient.

7. What is matplotlib and pylab?

matplotlib is a python 2D plotting library which produces publication quality figures in a variety of hard-copy formats and interactive environments across platforms.

The package pylab combines matplotlib, scipy with numpy into a single namespace.


    from pylab import *

That gets them NumPy, SciPy, and Matplotlib. A rough equivalent would be:

   from pylab import *
   from numpy import *
   rom scipy import *
plotting commands
