How I increased performance (use Secondary memory for RAM) of my phone





Hello all readers , This post is for those who want to increase the performance of their Android Mobile devices. This would feature the steps that I applied to increase the performance of my Phone and hopefully this would also increase the performance of your phone.





Step 1. First Root your Android Device

Root: means to break the barrier of root user, we are mere client user who works in the restricted environment of our Android phone (build on Linux Kernel, those who know Linux knows very well of being a root user).

Step 2. After Rooting the device you will need the Application named "Swapper Configuration".

Swapper Configuration : https://play.google.com/store/apps/details?id=org.azasoft.free.swapper&hl=en



Basically It is using the concept of Operating System Memory management called Swapping. Swapping is the process of removing the currently running program from memory (called swap out) and bringing in another program in to the memory (swap in).

Now Specify the details of Swap File Position and Swap File Size and tap save. Now restart your device and see the difference, you will love it.

Making a wifi hotspot in Ubuntu to be used for Android , ios and Windows phone






Hello guys , we know that people want to use the working internet not on one device but on different devices and there would be the case when on the go you would not be able to carry your wifi router to make it happen, well here comes the wifi hotspot come into play. When one machine would be created as a hotspot which share its network to the other devices as well in Windows machine it is quite easy as you just need to use a software named Connectify (and there might be some more), but in Ubuntu you have in-built options provided by Ubuntu to connect other devices. The following video would show you how to make a wifi hotspot in Ubuntu Operating System please have a look.


Ubuntu Linux Toolbox: 1000 + Commands for Power Users





But one problem everyone would come up , why this does not connect the android phones or ios phones to the internet. For this you need to create an access point supported by your mobile devices because android , windows phone does not support the ad-hoc networks. 

For ubuntu 12.04 use the below commands

sudo add-apt-repository ppa:nilarimogard/webupd8

sudo apt-get update

sudo apt-get install ap-hotspot
For Ubuntu 14.04 you need to downgrade the hostapd so please do that using the following commands

  1. First uninstall the buggy hostapd in Ubuntu 14.04 via:
    sudo apt-get remove hostapd
  2. Copy and paste the command below into terminal that matches your OS type – check out via System Setting -> Details – and hit run to download, install, and hold the old version of hostapd.
    While running the commands below, type in your user password in terminal when prompt.
    For 64-bit system:
    cd /tmp && wget http://archive.ubuntu.com/ubuntu/pool/universe/w/wpa/hostapd_1.0-3ubuntu2.1_amd64.deb && sudo dpkg -i hostapd*.deb && sudo apt-mark hold hostapd
    For 32-bit system:
    cd /tmp && wget http://archive.ubuntu.com/ubuntu/pool/universe/w/wpa/hostapd_1.0-3ubuntu2.1_i386.deb && sudo dpkg -i hostapd*.deb && sudo apt-mark hold hostapd


after the whole process use the following command

sudo ap-hotspot configure

and Finally start the hotspot via this command.

sudo ap-hotspot start
after all this you will get your hotspot working enjoy the internet.

MOOC (Online Course) to watch out: Learn to Program: The fundamentals Coursera



The course Learn to Program: The Fundamental offered by University of Toronto on Coursera, aims at providing the basic introduction about programming to the beginners using the the easy and readable programming language Python. The course is good for those who has learnt some basic computer science stuff and also for those who wants to get their hands on Python programming language. The Exercises and quizzes are very easy and everyone can complete it by giving just 1-2 hours a day watching videos and doing quizzes and assignments. Moreover you can find a good community in forums to help you out with learning and sharing more and more.

The course offers a certificate so that adds one more reason to do this course. I have completed this course and here is my certificate I am sharing with you.  This is just a stepping stone towards using python to solve the problems.

MOOC (Online Course) to Watch out: Intro to Computer Science 101 CS101 Udacity






Hello, everyone after moving to university from Schools we need some good exposure to the field we are studying. I am studying Computer Applications and I found a good resource to get people started with computer science from the beginning. If the people have taken the introductory course of computer science in college earlier and still do not feel confident about what they have learnt and want to develop themselves. They must do it.

Intro to Computer Science CS101 offered on udacity introduces computer science to the people. The basic stuff like software , hardware and the most important to instruct the computer is the programming language and in this course they have used python 2.7 to introduce the newbees programming and one more benefit is that at the end of the course you would finish up making your own web crawler or web spider written in python. Web crawler is a program search engine like Google uses to find pages and index them according to the page attributes (page rank, most visited pages, max occurrence of the word on the page) of the webpage. Moreover you can find a good community in forums to help you out with learning and sharing more and more. So have a look at that I have completed the course and received a nice certificate and I am very happy to share it with everyone.
