OpenRefine - A Good tool for refining and cleaning the data and useful for Feature Engineering

Ubuntu WiFi Driver Fix

 I have seen lots of people facing the problem of WiFi Driver support to the Debian based system like Ubuntu.

The Following is the solution to the problem.

step 1) Open terminal 

step 2) type lspci -nnk | grep -i network -A2 command in the terminal to know the network controller  information

if the driver network controller Provider is Broadcom Corporation  the output will be like below

or else if the network controller provider is Realtek Semiconductor Co., Ltd then the output will be like below

STEPS TO FOLLOW FOR BROADCOM CORPORATION CONTROLLER:

Broadcom Wireless driver can be installed using Additional Drivers application in Ubuntu 13.10, 13.04, 12.04, 11.10, 11.04, 10.10, 10.04.

To Open Additional Driver Application

If your using Unity then goto dashhome and search for Additional Drivers, then open it. Check the screen shot below.

Others, goto System->Administration->Additional Drivers. Check the screen shot below.

Once you open the application it will search for the available drivers, for your machine. Check the screen shot below.

After searching it will show you a list of drivers available for your machine, check the screen shot below.

From the list select Broadcom Wireless Driver and click on the Activate button. Provide password for the user when prompted

Once it finish installing the driver, Restart your system.

After restarting your system the driver is activated and you can use the wireless network.

Supported Driver

Broadcom STA Wireless driver

This package contains Broadcom 802.11 Linux STA wireless driverfor use with Broadcom’s BCM4311-, BCM4312-, BCM4313-, BCM4321-,BCM4322-, BCM43224-, and BCM43225-, BCM43227- and BCM43228-basedhardware.

Broadcom B43 Wireless driver

This package installs the firmware needed for usage of the b43 kerneldriver. Supported chipsets:- BCM4312 (with Low-Power aka LP-PHY)

you are done with the installation

STEPS TO FOLLOW FOR REALTEK NETWORK ADAPTER :

STEP 1)go to

 https://github.com/gopiprasanthpotipireddy/rtlwifi_new/archive/rock.new_btcoex.zip 

and Download the .zip file

STEP 2) unzip the rtlwifi_new-rock.new_btcoex.zip into a directory name it as                  rtlwifi_new-rock.new_btcoex

STEP 3) type cd rtlwifi_new-rock.new_btcoex in the terminal

STEP 4) find a file named wifi.sh

STEP 5) run the shell script in the console like sudo sh wifi.sh

STEP 6) The drivers will be installed and reboot the system after installation

                                            

                                      Hope this will be helpful for you!!!

Swecha Freedom Box

swecha freedom box is all about to decentralise the internet .internet is network of networks. it's all those who are using the internet .Every person using internet is a part of the network.       Here one person or some group of people don't have control over the internet.internet is not google and not facebook and not twitter or any else. Internet is net work of things.Any one  having interest to share and learn things can join in the network .

          But in present days the internet is in some ones hands and they all controlling our freedom of learning.they all monitoring each and every second , all eyes on our interests .we are the people to control the internet but the scenario is internet(sorry some software industries) is controlling us.

The swecha freedom box is to create our own network and to share our things in a decentralized way.
it is still in testing stage. it's all based on open source technology .it's made using open hardware like beagle bone.the core or hardware part is beagle bone . with the concept of freedom box we can achieve free communication . it is very useful in villages and semi urban areas to communicate .
   We are the people to contribute our knowledge towards development of freedom box.

      i am learning things to contribute my work  to freedom box.

       who is next ?????

A perspective on Indian Society(Btech-Project),Data Science

"A perspective on Indian society" is a Data Science project analysed on education in India ,Wage and salary dependencies in India,Child death and child marriage rates India etc...

Before the 3rd year i don't have any knowledge about my project ,In the 3rd year i decided my project should be from data science field as data science provides great insights about people thoughts and can create solutions to the public problems. It fulfills my dream of technical social responsibility in my four years BTECH-CS  and
adds a great achievement to my BTECH-CS Degree. 

  Every human take many actions in his/her day to day life. Few actions of humans
knowingly or unknowingly affects their standard of living . Sometimes their
actions creates unknown problems. The project “ A Perspective on Indian society ”
is to address such problems by querying through different fields of different
varieties of data sets which directly or indirectly affects the human daily routine
and the living strategy of human. The data sets are obtained from the human
activities observed in medical , educational, professional and rural and urban
standard of living data. The data sets may contain several thousand tuples.
There are several hundreds of fields to query and represent the reports
graphically. So, the development environment and tools must support to handle
scale very large data sets and to compile the complex weighted as well as
un weighted data.
“A Perspective on Indian society “ study/analyse the development
index by analysing the Diverse areas that reflect standard of living of People. we
also report increased the growth index for each of the diversities. This survey data
analytics is very useful in finding the keys to unlock the human problems by

showcasing the patterns hidden in the surveyed data.

Manual Scavenging in India

My opinion on Manual Scavenging in India  :   This is not a project file or any programming code , the below code embeds my opinion on manual scavenging in India.....      plzzz comment your opinion on manual scavenging in India after understanding the below code and watching the videos .....

class Parent_ManualScavenger throws  DonotCleanMyHouse,Street,Toilet,RoadException{

public Home h[];
public Road r[];
public Street s[];
public static String cast;            //entire class qualifies with its cast

public String name;

String myWork(Home h,Road r,Street s,Toilet t){        //this is our work

h.clean();  //clean every home
r.clean();  // cleans every road
s.clean();  // cleans every street
t.clean();  // cleans every toilet
return "every thing is cleaned and manual scavenging is my work";
}



String fightAgainstGoverment(Public p){

 String status=p.letsFight();         //Fight Against Government

return status;
}

}



class Child_ManualScravenger extends Parent_ManualScavenger throws     DonotCleanMyHouse,Street,Toilet,RoadException{

public static String cast;                      // we are too qualified with our cast

public String name;

String doyourwork(){

Home h=new Home;
Road r=new Road;
Toilet t=new Toilet;
Street s=new Street;

String workStatus=super.myWork(h,r,s,t);      /* even i  want to do mywork because that i am                                                                         child of a manual scavenger i do my parents job only */
                                                                                  

return workstatus;
}

String fightAgainstGoverment(Public p){

 String status=p.letsFight();         //Fight Against Government

return status;
}

}


public class Public{


Public static void main(String argv[]){

/* This block is entirely for your hands

if u want to fight  against manual scavenging wake up the government by protesting against government and public [fightAgainstGoverment()]

                    (or)

else if u dont want to do make the manualscavengers to wake up and fight [fightAgainstGoverment]


                     (or)
else  wake them up to clean your streets by making instances of them and waking doyourwork() up as usual;

Kakkos is a documentary film on manual scavengers directed by a young lady Divya from Tamilnadu
The below is a song from the documentary

Some other Tedx documentary on manual scavenging in India.
