[How to] Connect an android device [using MTP] on Linux [Ubuntu 14.04 LTS] 100% working

I recently moved to Linux[Ubuntu 14.04 ] from windows 8.1 because it hangs a lot on my lappy. Apart from the cool features of Ubuntu , one thing was annoying me that I was unable to connect my android phone [Asus zenfone 4 TOOi] and thus was unable to transfer any files via usb using MTP. After searching a lot I finally got the working answer on ubuntuforums.org which I'm again explaining it here again as simply as possible.
First of all you must have an active Internet connection.
Step 1:
First we need to install some necessary tools for MTP detection in Linux[Ubuntu]
open terminal and type the following command

 sudo apt-get install libmtp-common mtp-tools libmtp-dev libmtp-runtime libmtp9

 sudo apt-get dist-upgrade

MTP

Step 2:
Now we need to get vender and product ID
For that attach your android MTP device to your Linux system.
Type following command in terminal

lsusb

My output was as follows

Bus 002 Device 002: ID 8087:0020 Intel Corp. Integrated Rate Matching Hub
Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 001 Device 026: ID 0b05:580f ASUSTek Computer, Inc.
Bus 001 Device 025: ID 064e:c21c Suyin Corp.
Bus 001 Device 002: ID 8087:0020 Intel Corp. Integrated Rate Matching Hub
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
 The above one in red color is my device with It's vendor and id("0b05" and "580f")

Step 3:
Now we will amend the mtp udev rules as follows, from a terminal type

Code:

 sudo nano /lib/udev/rules.d/69-mtp.rules


Now, add the following line of code


# Asus Zenfone 4 TOOi
ATTR{idVendor}=="0b05", ATTR{idProduct}=="580f", SYMLINK+="libmtp-%k", ENV{ID_MTP_DEVICE}="1", ENV{ID_MEDIA_PLAYER}="1"



Note: change the vender and product id as of your device(In red color in this post) and you can also change the device name after # as per your wish but it is not necessary.

When you are done editing, save the file(Ctrl+c, then Y and then enter)

Step 4:
The next step would also be to add a line of code to the 51 android rules file, again from a terminal type

Code:

 sudo nano /etc/udev/rules.d/51-android.rules


Then add the following line of code

Code:

ATTR{idVendor}=="0b05", ATTR{idProduct}=="580f", MODE=”0666"


Remember to change the vender id and product id as per your system(shown in red color)

When you done, save the file.

Step 5:
Type the following code in terminal


 sudo service udev restart


after this, save all your work because we will reboot your system

Step 6:

Type following command to reboot your system

sudo reboot

Additional Optional work:
If you want to work with nice GUI with your MTP device rather than using default file explorer of Ubuntu/Linux
try following command

sudo apt-get install gmtp


or you can also download this from software center.

JAVA Ring

Well I really don't know how old or new this terminology is. I came across this when one of my faculty asked me about it but I unable to answer it. So just like other curious and lazy students, I googled the term to to get  a small  knowledge about it.

Today I'm going to share with the same knowledge I captured from some scratch resources.

Java ring is a finger that contains a small microprocessor with built in capabilities for the user.
java ring s a sort of smart card which can be put on a finger. It is a stainless steel ring with 16 millimeters (0.6 inch) of diameter.

 It contains an inexpensive microprocessor in a stainless steel iBUTTON which runs JVM and preloaded applet within it. Java ring in an extremely secure java powered electronic token. It has number of real world applications. It contains a tiny Java Virtual Machine. It implements the JAVA card 2.0 API. Stores information in NVRAM, ROM. It runs applets.
It includes microprocessor, clock, memory and battery.

JAVA ring components include

• JAVA virtual machine(JVM)
• RAM
• ROM
• real time clock
• iBUTTON
• Blue dot receptor

The Java Virtual machine (JVM) is the virtual machine that run the Java bytecodes. 

RAM

JAVA ring contains a 134kb nonvolatile RAM. This nonvolatile RAM provides high speed for read/write operations. It also provides zeroization.
ROM
JAVA ring contains 32kb of ROM. "e-commerce " operating system is installed in this ROM.

REAL TIME CLOCK
It gives exact time of the day and can run upto 10 years continuously. It is driven by 32Khz crystal oscillator. The frequency of processor clock varies from 10-20 Mhz. This prohibits the hackers from obtaining information from iBUTTON.

iBUTTON
It is a computer chip enclosed in a thick stainless steel can. It is also called "touch memory device". JAVA ring uses 1-wire protocol to communicate between host and iBUTTON.
It is similar to a disk shaped battery.Each iBUTTON has a unique and unalterable address laser attached onto its inside the can lid. The address can be used for identification.

Blue Dot Receptor
These are iBUTTON readers that provide a convenient pipeline into the PC for iBUTTON to PC communication. The receptor's cable connects a USB, serial or parallel port 1-wire adapter.

Me versus myself

This post again revolves around the "ordinary kid" the same as in the poem "Everything left behind" which I wrote as a page few months ago .
The story is nearly of 19 years ago .
A woman in some small town of Rajasthan village gave birth to a boy.
The woman already had 2 girl child and her economic condition was not so good .
That woman also had a younger sister who once had a miscarriage and then after that never got pregnant. She asked her elder sister to adopt her youngest child which she frequently gave birth.
The elder sister denied to give her child forever to her but she had a proposal.
She said to her younger sister that she could take the child for some time to nourish him in return of some money.
It's hard to believe but the elder sister gave her child to younger sister in change of some money .

The younger sister lived with her husband in some hilly areas of j&k as her husband was in military and was posted there.

There were no elders in there house and that woman had no experience of how to raise a child.

She never let the child to see outside world, she never let him to play with the other kids, she just kept him inside the house and used to beat him for every single thing, whether right or wrong, even she used to show off her anger on him, the child was nothing to her but just a thing for which she paid.

There was no one to whom the child could share his feelings and sufferings with. He was lost within his own personality.

He was blamed for everything wrong that happened in the house and their life.
He never received a love of his parents.
The boy now studies in an engineering college at Jaipur,India.
And he fed up of his life.

If this continuous to him, he won't be able to tolerate it and will suicide.
