WOMEN AND TECH-WORLD

“Day and night woman must be kept in dependence by the males (of) their (families).Her father protects (her) in childhood, her husband protects (her) in youth, and her sons protect (her) in old age; a woman is never fit for independence.”     The Laws of Manu, c. 1500 BCE CHAPTER IX

This was the old convention that considered women to be a symbol of softness, an enigma of emotions and a dependent of man. Today such a thought is irrelevant, but still there are many who think that women can never reach the constraints of a successful man. A successful man defines himself with the qualities like power, influence and independence, and these are considered to be the traits of a successful person.  We can find only a fewer number of women who strive to reach such peak positions. So what are the traits of a successful woman? Don’t these women have the same traits as that of the men or do they have something else that triggers them but in a different manner?
Women are like the hidden unpolished diamonds; their character can come to the limelight only if they are smoothed and sharpened where ever necessary. She has the sense of empathy, influence and can manage the conflicts efficiently.
Some traits of women are usually assessed to be non-profitable in a money oriented environment. She empathise and makes the decision-making procedure a really tiring one. But don’t these people understand that empathy is such a feeling that can make the relations stronger, it’s the same feeling that decreases the distance between an employer and employees. A sense of dedication and gratefulness to the company and for the employer can be ignited with the same feeling. Empathy when used in a different angle can be utilized to influence people and make the execution procedure a really simple and organized. The power of empathy can be handled well by women.
Conflict management is yet another area where women seemed to be experts. The daily challenges and adjustments that they make in their personal life aids a woman to take the right actions for her firm. The constant exposure to conflicts helps women to adapt to the new ambience without many tantrums.
“In politics, If you want anything said, ask a man. If you want anything done, ask a woman.” -Margaret Thatcher
Men usually consider women to be insecure. They think that women spent too much time in thinking about what others may think about them. Men usually  think that decision-making is the primary goal and that the impact it will have on others is secondary. That’s why when men take an anti-family policy they are less criticized than a women who takes such decisions. Critics expect women to understand the impact of these and at the same time expect women to be strict in taking such a step. If she contemplates with those decisions she is considered to be weak and if she makes stern decisions she is given a negative image. So what should she do?
The mind-set to think what others may think about them leads gives them a sense of self-awareness which is essential for the growth of an individual.
Women are aware about the competition that they have to face in this technical world. They try to adapt themselves to such competitions by enhancing their capabilities. They are constant learners even in the  They try to develop their skills and excel in them to prove their worth they always undergo through many tests and surely the test of iron makes the finest steel. Soft skills of women often excel than that of men. There are many problems faced by women when she needs to make a decision as a leader. She is expected to emphasis with others and if not she will have to face the warth.negative if she found to be too soft she is considered to be granted. And her efforts are not valid. If she becomes bold she is commented to be bold and too masculine in stereotype.Whether or not gender characteristics are inherited or socially constructed no longer matters as much as our ability to use what we’ve got to our own advantage.
As per the studies we can see the ruling of women in internet. Making use of social networks to interact and influence the people has now become more advantageous for the women community. Women leaders mostly utilize these to make sure that they have got a network that can accommodate them with he .These have transcended he physical cultural and national boundaries. Women often showcase their talents through their blogs and websites. In this case they have overpowered men population. They popularise their creative side and make the best out of it. Homemakers are now not just a kitchen holder but a master in networking. She gathers the people around her with the skills,  it may be through her stories, ornament, craft, cooking classes. Whatever it is, women have become the queen of internet. Market place has now found the new faces…tech industry will surely welcome the innovations and experiments with the mentality change. Men conquer women collaborate…

HADOOP INSTALLATION ON SINGLE NODE UBUNTU 12.04

    INSTALLATION GUIDE FOR HADOOP IN UBUNTU 12.04 (SINGLE NODE)

 

Installing Java-7-oracle

 

sudo add-apt-repository ppa:webupd8team/java

sudo apt-get update

sudo apt-get install oracle-java7-installer

 

 

Create a separate user for hadoop

 

$ sudo addgroup hadoop

$ sudo adduser –ingroup hadoop hduser

 

Configure SSH

 

su – hduser

ssh-keygen -t rsa -P “”

 

To be sure that SSH installation is went well, you can open a new terminal and try to create ssh session using hduser by the following command:

$ssh localhost

 

if localhost is not connected reinstalltion of ssh is needed

 

sudo apt-get install openssh-server

 

Edit Sudoers

pkexec visudo

 

Add below line to add hduser into sudoers

hduser (ALL)=(ALL) ALL

 

Ctrl + O to save nano 

 

and exit from the editor  

 

Disable IPv6

 

 

$sudo gedit /etc/sysctl.conf

This command will open sysctl.conf in text editor, you can copy the following lines at the end of the file:

 

#disable ipv6

net.ipv6.conf.all.disable_ipv6 = 1

net.ipv6.conf.default.disable_ipv6 = 1

net.ipv6.conf.lo.disable_ipv6 = 1

 

If you faced a problem telling you don’t have permissions, just remember to run the previous commands by your root account.

These steps required you to reboot your system, but alternatively, you can run the following command to re-initialize the configurations again.

 

$sudo sysctl -p

To make sure that IPV6 is disabled, you can run the following command:

$cat /proc/sys/net/ipv6/conf/all/disable_ipv6

 

Configuration of Hadoop

Installing Hadoop

 

Now we can download Hadoop to begin installation. Go to Apache Downloads and download Hadoop version 1.0.4.(current stable version)

Then you need to extract the tar file and rename the extracted folder to ‘hadoop’. Open a new terminal and run the following command:

 

$ cd /home/hduser

$ sudo tar xzf hadoop-0.20.2.tar.gz

$ sudo mv hadoop-0.20.2 hadoop

 

Update $HOME/.bashrc

You will need to update the .bachrc for hduser (and for every user you need to administer Hadoop). To open .bachrc file, you will need to open it as root:

 

$sudo gedit /home/hduser/.bashrc

 

Then you will add the following configurations at the end of .bachrc file

 

# Set Hadoop-related environment variables

 

export HADOOP_HOME=/home/hduser/hadoop

 

# Set JAVA_HOME (we will also configure JAVA_HOME directly for Hadoop later on)

 

export JAVA_HOME=/usr/lib/jvm/java-7-oracle

 

# Some convenient aliases and functions for running Hadoop-related commands

 

unalias fs &> /dev/null

alias fs=”hadoop fs”

unalias hls &> /dev/null

alias hls=”fs -ls”

 

# If you have LZO compression enabled in your Hadoop cluster and

# compress job outputs with LZOP (not covered in this tutorial):

# Conveniently inspect an LZOP compressed file from the command

# line; run via:

#

# $ lzohead /hdfs/path/to/lzop/compressed/file.lzo

#

# Requires installed ‘lzop’ command.

#

lzohead () {

    hadoop fs -cat $1 | lzop -dc | head -1000 | less

}

 

# Add Hadoop bin/ directory to PATH

export PATH=$PATH:$HADOOP_HOME/bin

 

 

hadoop-env.sh

We need only to update the JAVA_HOME variable in this file. Simply you will open this file using a text editor using the following command:

 

$sudo gedit /home/hduser/hadoop/conf/hadoop-env.sh

 

or

 

nano /home/hduser/hduser/hadoop/conf/hadoop-env.sh

 

Then you will need to change the following line

 

# export JAVA_HOME=/usr/lib/j2sdk1.5-sun

 

To 

 

export JAVA_HOME=/usr/lib/jvm/java-7-oracle

 

Note: if you faced “Error: JAVA_HOME is not set” Error while starting the services, then you seems that you forgot toe uncomment the previous line (just remove #).

 

core-site.xml

First, we need to create a temp directory for Hadoop framework. If you need this environment for testing or a quick prototype (e.g. develop simple hadoop programs for your personal test …), I suggest to create this folder under /home/hduser/ directory, otherwise, you should create this folder in a shared place under shared folder (like /usr/local …) but you may face some security issues. But to overcome the exceptions that may caused by security (like java.io.IOException), I have created the tmp folder under hduser space.

 

To create this folder, type the following command:

 

$ sudo mkdir  /home/hduser/tmp

 

Please note that if you want to make another admin user (e.g. hduser2 in hadoop group), you should grant him a read and write permission on this folder using the following commands:

 

 

$ sudo chown hduser:hadoop /home/hduser/tmp

 

$ sudo chmod 755 /home/hduser/tmp

Now, we can open hadoop/conf/core-site.xml to edit the hadoop.tmp.dir entry.

We can open the core-site.xml using text editor:

 

$sudo gedit /home/hduser/hadoop/conf/core-site.xml

 

or

 

nano /home/hduser/hduser/hadoop/conf/core-site.xml

 

Then add the following configurations between .. xml elements:

 

  hadoop.tmp.dir

  /home/hduser/tmp

  A base for other temporary directories.

 

  fs.default.name

  hdfs://localhost:54310

  The name of the default file system.  A URI whose

  scheme and authority determine the FileSystem implementation.  The

  uri’s scheme determines the config property (fs.SCHEME.impl) naming

  the FileSystem implementation class.  The uri’s authority is used to

  determine the host, port, etc. for a filesystem.

mapred-site.xml

We will open the hadoop/conf/mapred-site.xml using a text editor and add the following configuration values (like core-site.xml)

nano /home/hduser/hduser/hadoop/conf/mapred-site.xml

 

  mapred.job.tracker

  localhost:54311

  The host and port that the MapReduce job tracker runs

  at.  If “local”, then jobs are run in-process as a single map

  and reduce task.

 

hdfs-site.xml

Open hadoop/conf/hdfs-site.xml using a text editor and add the following configurations:

 

nano /home/hduser/hduser/hadoop/conf/hdfs-site.xml

 

  dfs.replication

  1

  Default block replication.

  The actual number of replications can be specified when the file is created.

  The default is used if replication is not specified in create time.

 

Formatting NameNode

~/hduser/hadoop/bin/hadoop namenode -format

 

You should format the NameNode in your HDFS. You should not do this step when the system is running. It is usually done once at first time of your installation.

Run the following command

 

$/home/hduser/hadoop/bin/hadoop namenode -format

 


NameNode Formatting

Starting Hadoop Cluster

You will need to navigate to hadoop/bin directory and run ./start-all.sh script.

cd ~/hduser/hadoop/bin/

./start-all.sh

 


Starting Hadoop Services using ./start-all.sh

 

There is a nice tool called jps. You can use it to ensure that all the services are up.

WINDOWS DESKTOP CUSTOMIZATION

 

 

This post will help you turn your desktop into a productive and nice looking space which you can customize every day. The interactive panels provide specific information so you wont have anything unnecessary on your desktop. 

TOOLS NEEDED:

HOW TO?

  • Install Rainmeter which we downloaded.
  • After that, run Rainmeter close it. To close it, right click on the Rainmeter icon on the task-bar and click “Exit” 
  • Now, extract the contents of the “Omnimo 2 for Rainmeter” that you have downloaded
  • After that, select “Omnimo.rmskin” which is located within the extracted files
  • Now,install it
  • Finally, run “Rainmeter” and you’ll be greeted by your new Omnimo desktop!

you can even customize the skins by mixing up one with another.I used a mix of AVENGERS AND SPACE CRAFT  to give my desktop a new face..
