In India, if a guy took Maths stream, then no matter whether he deserves or not he became Engineer . So here in India, engineer is just like common students . Even, i saw cases when people do engineering and jump to clerical job . They think that the clerical job is more stable than engineering field in fact that’s true for now . It’s not because recession or like anything . It is because in reality they are not an engineer . They don’t know physical laws , have no creativity , no understanding of why algorithms are used , how computer do job in background etc .

It is the big problem. There might be few reasons why this is happening.

• Inadequate resources for engineers in engineering college .
• Poor Faculty service . Students are taught by local/unexperienced teachers .
• Unsystematic way of teaching .
• Undeserving students are becoming engineers .I think if somebody want to became engineer he has to prove it some manner that yes i am capable of .

This really take me down. When i say i am Software engineer to someone they just take it casually but if i say i am web developer they appreciate me . Since, i also did the engineering from Indian college and i know the problems,hopefully i want to fix it . Engineers are those people who will represent the nation . I wish government should take some action but i has no hope .

To fix those problems first i have became a real engineer . Yes, i too think that i need to learn many things which i didn’t got it properly when i was doing engineering . Earlier i just know the concepts but i have no idea where the knowledge can applied but after doing 1 year of freelancing i know what is the appropriate way to teach students . I not good in explaining things but atleast i should give a try .

After some months, most probably i will release some videos where i will try to cover engineering concepts.Yes, it will be free of cost but i am software engineer so i will just cover computer engineering concepts .

If you , reader, if you think you can teach it too in better any than else please do it . We need your support to make Education better.

Thanks .

It’s been a year since i started freelancing, it is going well but now i came to realized that i am not giving much time to my friends and family , i even didn’t took any holidays .

Most importantly , i am not doing what i about to do. So i have decided that i will not not accept any new project . Thanks :)

The official fedena installation guide is not fully documented and many people are unhappy. I tried myself to help all whole peoples. There are two ways to install fedena . automatic and manually. automatic installation not works everytime , but you can give a try first . Vist

  https://www.github.com/passion8/fedena-install/

if it works for you, then its great. Else follow the below manual guide .

1. Login to your root server and create deployer account with sudo access. And login to that a/c . You can use

   sudo adduser deployer
   sudo adduser deployer sudo
   su deployer 
   cd ~
   

2. Now install the dependency . Copy the below lines and paste in into terminal one by one

   sudo apt-get -y install wget curl build-essential 
   sudo apt-get -y install bi
   son openssl zlib1g clang  
   sudo apt-get -y install libxslt1.1 libssl-dev libxslt1-dev make
   sudo apt-get -y install libxml2 libffi-dev libyaml-dev 
   sudo apt-get -y install libxslt1-dev autoconf libc6-dev 
   sudo apt-get -y install libreadline6-dev zlib1g-dev 
   sudo apt-get -y install libcurl4-openssl-dev
   sudo apt-get -y install  libtool  libcurl4-openssl-dev
   sudo apt-get -y install libssl-dev apache2-prefork-dev 
   sudo apt-get -y install libapr1-dev libaprutil1-dev make
   

3. Now install the sqlite .

   sudo apt-get -y install libsqlite3-0   sqlite3 libsqlite3-dev libmysqlclient-dev
   

4. Now install image resizing and cropping tool

   sudo apt-get -y install  libmagickwand-dev imagemagick
   

5. Now install git

   sudo apt-get -y install git-core
   

6. Now install apache2 

   sudo apt-get -y install apache2
   

7. Now install mysql server

   sudo apt-get -y install libmysqlclient-dev  mysql-server mysql-client
   

8. Now install RVM

   curl https://raw.github.com/wayneeseguin/rvm/master/binscripts/rvm-installer | bash -s stable
   echo 'source ~/.bashrc' >> ~/.bash_login
   . ~/.bash_login
   

9. Now install the missing dependency. Do

   rvm requirements
   

   And, install the missing package(s).

10. Now install Ruby 1.8.3

    rvm install ruby-1.8.7-p371
    rvm alias create default ruby-1.8.7-p371
    

11. We dont want documentation so do and install the required fedena gems.

    
    echo "gem: --no-ri --no-rdoc" >> ~/.gemrc
    gem install bundler 
    gem install rails -v 2.3.5 
    gem install  i18n -v 0.4.2 
    gem install  declarative_authorization -v 0.5.1 
    gem install  mysql -v 2.8.1 
    gem install  rake -v 0.8.7 
    gem install  rush -v 0.6.8
    gem install passenger
    

12. Downgrade the rubygem

    gem update --system 1.4.2
    

13. Make the production environmenet

    echo 'export RAILS_ENV=production' >> ~/.bashrc
    source ~/.bashrc
    

14. Remove the latest rake which is been installed . first check rake version by

    gem list rake -d
    

    Now, remove the latest rake verion . In my case it is rake 10.04 so i did the following

    rm ~/.rvm/gems/ruby-1.8.7-p371@global/bin/rake
    rm ~/.rvm/gems/ruby-1.8.7-p371@global/cache -rf
    rm ~/.rvm/gems/ruby-1.8.7-p371@global/gems/rake-10.0.4/ -rf
    rm ~/.rvm/gems/ruby-1.8.7-p371@global/specifications/rake-10.0.4.gemspec  -rf
    source ~/.bashrc
    

    Now check the rake version by doing rake -v. If it only contains 0.8.7 than move to next step.

15. Install the fedena and move to the directory

    wget http://www.projectfedena.org/download/fedena-github -O fedena.zip
    unzip fedena.zip && mv projectfedena-fedena* fedena/  && cd fedena
    

16. I wrote one script which will update the fedena database file to your root password.please replace mypassword with your password. so, do

    wget https://raw.github.com/passion8/fedena-install/master/ymlwriter.rb
    ruby  ymlwriter.rb mypassword
    rm ymlwriter.rb
    

17. Now , we will run fedena rails command . First create the database.

    rake db:create
    

    if it is saying that they were not able to make the database because of server incorrect credentials , then you go to 16 step and start again .

18. Now its time to install plugins and its associated tables.

    rake fedena:plugins:install_all
    

19. Make the script executable and then run passenger command .

    chmod +x script/*
    passenger-install-apache2-module
    

20. Follow instruction . Usually, we have to edit /etc/apache2/httpd.conf file for popping passenger configuration.

That’s all . if you have any problem , do comment . Thanks :)

oteupload.com is fraud . Last month i updated my account from normal to premium since i have to download lots of data from oteupload server . I can’t tolerate low speed . And, at the end of the month i went to the website to down-grade my a/c but i didnt find any way . There is no way to downgrade your a/c . So i sent email to oteupload.com and fortunately I got a quick response , i thought may be because of heavy market competition they are using trick and only down-grading is possible if we send person email to them .

The email which i receive is requesting my billing name and email id and saying me to forward this details to sales department, i sent all the required details . . Now, they were not replying me , i sent polite emails and requested them to downgrade the service . But still i didn’t got any response . I use twitter to contact them but still as usual no response .

And, finally the the date came and its time for renewal. I was confused and getting the feeling how the user feels when they know/have nothing and been screwed up by internet companies . I have no choice . So i gave up . Suddenly I got one email and it says they failed to deduct money from my a/c since it is protected . That email is automated email and it is been not by oteupload.com but the service which oteupload uses internally for payment . Thankfully that services allow me to change my card number and other details so i did .

I have protected my card with one pincode which dont allow automatic payments . I suggest you to take some extra steps to protect your card and try to do everything not to disclose your card details to some third party service . Internet is the big ocean , some are good fish but not all . If paypal is available in you country , use paypal . You can trust paypal

. That’s all . :)

From now onwards you can access my blog to with paritosh.passion8.co.in . Cheers .

Today i attended https://venture-lab.org entrepreneurship classes online . Since today is just the introductory class i have no idea what i will learn it and how they will teach me . I am blindly obeying them .

1st they suggested us to form a team so i just went to the forum and put my post, you can check  . I hope  that during this venture-lab course journey i will make new friends and learn to work with the team. If you are interested in joining me, you can email me . 

Yes, if  I find some good team i will also  publish my startup and work for it .

Hi guys,

We came back again to objects. It is big topic and to became comfortable in javascript , object deep knowledge is required . i cant skip it . So,without future dao , lets dig in.

Remember i told you that bracket notation is another way to access its value inside the objects . Bracket notation supports variable . so , if you write obj[var1] . it will substitute its variable . Dot notation fails here . we cant use obj.var1 .

For iterating all objects properties , we have special loop. known as for-in loop . lets take an example .

var obj1 = {  first_name : "paritosh", last_name : "piplewar" } 
for(var property in obj1){ 
  console.log(property + " : " + obj1[property]); 
}

In my previous guide,i taught you how to create constructor . In javascript , it is analogous with class , we define class in same way . Technically both are different, but this concept is confusing , so dont appy it here .

So, lets jump into prototype .

What is prototype ?

It is the property which spy all class methods and attributes. Prototype is often used to extend the class/constructor property by this syntax .

className.protpotype.newMethod = function() {}

You must be thinking what is the need to learn this concept. It is sometimes a situation where we cant change classdefinition, so we use prototype property . Let suppose , we want to add property in Array class. so

Array.prototype.firstElement = function() {
  console.log(this[0]);
}
var arr2 = new Array();
arr2[0] = second;
console.log(arr2.firstElement());

Prototype is much more then that. We can inherit all class methods and attributes . Syntax is

childClass.prototype = new parentClass();

You can also declare private variable inside class. Its is so easy but just somewhat tricky. We use variable scope concept , variable which is defined inside block cant be accessed outside the block . if we try , we will get undefined . so, inside the class , we can use get / set methods for private attributes or/and methods . Like

var clas1 = function(college) {
  var collegeName = college;
  this.name = paritosh;
  this.getCollegeName = function() {
    return collegeName;
  }
}
cls1 = new clas1(JEC);
console.log(cls1.getCollegeName());

This is for all now. Learn all this concept .
