Quick Linux Tutorial For Beginners Series

Linux introduction lesson1 

Linux is an open-source operating system it is a collection of software, each designed for a specific function.

Why Use Linux

Linux is completely different from other operating systems in many ways.
  • It is an open source OS which means that developers an design their own custom operating systems

  • A global development community look at different ways to enhance its security, hence it is highly secured and robust so you don't need an anti virus to scan it regularly.

  • Above all you don't have to pay for software and server licensing to install Linux, its absolutely free and you can install it on as many computers as you want.

  • Its completely trouble free operating system and don't have an issue with viruses, malware and slowing down your computer.


Linux OS has following components:

1) Kernel

It is the  brain of system it dose alot of work such as 

Device management: like CPU, memory device, sound cards, graphic cards, ...  kernel stores all the data related to all the devices in device drive.

Memory management: Kernel keeps a track of used and free memory and make sure that processes shouldn't manipulate data of each other 

Process management:  kernel assign time and gives priorities to processes before handling CPU to other process

Handling system calls: Handling system calls query or ask the kernel to perform a task

2) System Libraries

System libraries are special programs that helps in accessing the kernel's feature

3) System Tools

a set of utility tools which are usually simple commands With the help of them you can access your files, edit and manipulate data in your directories or files, change location of files and much more 
 

4) Development Tools

With the above three components your OS is running and working. But to update your system you have additional tools and libraries.

5) End User Tools

End tools are not required for the operating system but are necessary for a user to  accomplish his work  of end tools are graphic design tools, office suites, browsers, multimedia players, etc

There is many linux distributions such as linux mint ,Ubuntu ,debian ,Red Hat /centOS, Fedora in next lessons we will talk about Ubuntu distribution

ES6 : 5 Prevent Object Mutation

As seen in the previous post declaration alone doesn't really protect your data from mutation. To ensure your data doesn't change, JavaScript provides a function Object.freeze() to prevent data mutation. Once the object is frozen, you can no longer add, update, or delete properties from it. Any attempt at changing the object will be rejected without an error. let obj = { name:"FreeCodeCamp" review:"Awesome" }; Object.freeze(obj); obj.review = "bad"; //will be ignored. Mutation not allowed obj.newProp = "Test"; // will be ignored. Mutation not allowed console.log(obj); // { name: "FreeCodeCamp", review:"Awesome"}

ES6: 1 Explore Differences Between the var and let Keywords

One of the biggest problems with declaring variables with the var keyword is that you can overwrite variable declarations without an error. var camper = 'James'; var camper = 'David'; console.log(camper); // logs 'David' As you can see in the code above, the camper variable is originally declared as James and then overridden to be David . In a small application, you might not run into this type of problem, but when your code becomes larger, you might accidentally overwrite a variable that you did not intend to overwrite. Because this behavior does not throw an error, searching and fixing bugs becomes more difficult. A new keyword called let was introduced in ES6 to solve this potential issue with the var keyword. If you were to replace var with let in the variable declarations of the code above, the result would be an error. let camper = 'James'; let camper = 'David'; // throws an error This error can be seen...

CSS Grid: Reduce Repetition Using the repeat Function

 When we used grid-template-columns and grid-template-rows to define the structure of a grid, you entered a value for each row or column you created. Lets say you want a grid with 100 rows of the same height. It isn't very practical to insert 100 values individually. Fortunately, there's a better way - by using the repeat function to specify the number of times you want your column or row to be repeated, followed by a comma and the value you want to repeat. Here's an example that would create the 100 row grid, each row at 50px tall. grid-template-rows: repeat(100, 50px); You can also repeat multiple values with the repeat function, and insert the function amongst other values when defining a grid structure. Here's what I mean: grid-template-columns: repeat(2, 1fr 50px) 20px;  this will be translated to :            grid-template-columns:1fr 50px 1fr 50px  20px;   1fr 50px is repeated t...
