Md5 Hash fingerprint of the file. how?

In this post, I am sharing one basic information about file integrity method using MD5 Hash

What is Md5hash:

In every file has a unique hash created by themselves, this hash code was used to verify the file is modified or not,
simply tell the MD5 Hash is like a fingerprint of the file,

If you do any small change in file the total Md5sum hash value is changed totally,
 When you are download files such as Linux ISO images and others. At that time some of the hackers can change the file with another file looks same.

In generally the most of the Linux ISO sites gives the md5hash of the file, After downloading you must check the downloaded file mD5hash is equal to given MD5Hash code.
If your calculated hash code is different from given code, definitely your file is been corrupted or may be modified by others.

What is MD5Sum Tool:

MD5SUM is a tool, 
The tool preinstalled un Linux in command line Interface.

Let's find out MD5SUM:

For Example showing, I am created one small example python file to print hello world. 
After Creating a file > Open Terminal > Move on the File Directory >
Type    >md5sum (filename.extension)

An Example I have created a file named hello.py so I am typed md5sum hello.py  

Now it shows that Md5sum hash code

And Again I change a small change in the python file an Print "hello Linux user" 
After I am calculating the md5sum hash 
The total md5sum value is changed

In this screenshot shows on the first time I am created one python file and calculated that fuel Md5sum Hash 

In next, I am changed the file and again I am calculated hash is totally changed than before

That's a use of the Md5sum hash tool. 
And I say,  Lot of another best option is available to check the file integrity, Give me your support I am definitely posting about that, 
Thanks for reading the post.I hope this post really helpful for what is the Md5sum Hash, How to use Md5? And how to check the file integrity using Md5sum? And share this post Maximum.

[solved] High RAM usage in chromium in Ubuntu

 In this post, I am shared a solution of High amount of RAM consume in chromium browser in Ubuntu systems

Most of the Ubuntu users especially who have only 2GB of RAM memory capacity systems faced this problem 

Solution: High RAM usage in chromium in Ubuntu

We can't do anything in chromium memory usage, But we can stop the other components to occupy memory.

Some Extension is taking more amount of Memory, we can stop or find the best alternatives to solve the high level of memory usage in RAM

Adblocker plus:

The Adblocker is the popular Ad blocking extension in chromium app store, but negative thing of the extension is It consumes nearly 100MB of Memory Usage
Alternative:
I found a low RAM consume Adblocker in official chrome Store  Ublocker:
Ublocker is also good, the Main thing is it consumes only 40Mb of Memory only,

Task manager:

Same as chrome, the chromium also has an own Task manager,

press theshift+Esc button, then it pops up the task manager window, 

That task manager clearly shows the list of Memory usage and network usage in this list, If you find any unusual usage click the End process button.

Tabs:

The number of tabs you are using is the main reason for over memory usage and speed issues. Not all the page consume high memory, some of the page example screenshot here

Extension Manager:

We can use a multiple extension in same time, but not all the extension is essential every time,

Using some Extension switcher extension
An example Extensions Manager (aka Switcher) this add-on really helpful for switch on and off in extension

Get the Extension In this link:  Extensions Manager-Chrome store

I hope this post solve your high RAM consume in chromium in Ubuntu systems, If I found best alternatives in future I definitely update this blog, keep following this blog.
