Ruby - 1

Ruby is an interpreted language. Interpreted languages are those in which instructions are executed one by one.

If some one is new to programming field, he/she  will not be able to understand my above lines. Don't worry, my very next post will be dedicated to the it. Before starting any programming language, it is necessary to understand what actually a programming language is (especially if you are going to start your first language) and why it is different from others. Read my next blog and you will be able to understand what actually is programming language, why are we even learning it and what is the difference between scripting language, markup language and programming language. So for now, I will just introduce Ruby.

Ruby is object oriented. Don't worry, I will definitely explain "What does being Object Oriented mean?" and will explain after all "why we needed the language to be Object Oriented?" in my next to next blog.

After all these I will start with Ruby and will strictly talk about technology. I will also complete the topic on Git and explain SSH.

Before starting Ruby, we should keep following points in mind:

• Ruby looks easy and indeed the written code is easily understandable, but Ruby actually is very complex and error prone. 
• Ruby is more famous because of Rails, Rails is a web development framework.

Keep Learning, Keep Sharing..~~!!

Using Git

Everyone must have an idea of Git. If not, you are not following my blogs. Find it here: "Why Git?" (advertisement may come; skip if you want to)

Git is used to push repository from local to remote, clone and pull repository from remote to local. Lets get to the steps to do that directly. We will use terminal to write commands:

From Local to Remote

1. Go to the folder where your file is stored using 'cd' command. Suppose you are at home and the file is stored in Downloads. Go to Downloads by writing the command 'cd Downloads'. By the way, home can be reached by just typing 'cd' in the terminal. After reaching the Downloads, you need to initialize git here. Git can be initialized by writing 'git init' command. This should create a .git folder in Downloads.
2. Next step would be to add your file to the Git. Adding can be explained as picking a particular file from a list of files in that folder. This can be done with the command 'git add file_na, me.txt'.
3. git commit -m "any message". This command will commit the file to your git. Your push will come the message you write under the double inverted commas.
4. git remote add origin ...... This command will link your local to the remote. The address of the remote is written after origin. Origin is just name of your local repository. You can give any name.
5. Now this command will push your file to the remote: "git push origin master".

From Remote to Local

1. git clone ...... write this command in your terminal and repository will be saved into local.  The address of the remote is written after clone. Folder with the same name as the repository will be created in the directory where where you are currently.

Well this was all about pushing and cloning from local to remote and vice-versa. Any time you can run the command git status to check which files are added, which files are committed and which files are needed to be commit. There are many more thing which needs to be discussed about Git, but will leave it for the next time. I will also discuss about SSH.

From WINDOWS to UBUNTU

After using Windows OS for many years, it was quite difficult to switch over to UBUNTU. First impression for Ubuntu was: Its not that user friendly. The fact is, its simple, user friendly and programmer friendly.

Ubuntu is Linus based OS. Linux is the kernel of Ubuntu. kernel is something which makes possible for the OS to interact with the system's hardware. Fedora, Debian are other examples of Linux based OS.

Command line interface for Ubuntu is known as Terminal. (Ctrl+Alt+T) will open the Terminal for you. Following are some useful commands for Ubuntu beginners:

man : Opens Manual page of any command

ls : list of files and directories in your present directory

cd : change directory, (type cd name of directory)

mkdir : create a new directory

rm : remove files or directory

rmdir : removes directory

mv : rename files and directories

pwd : shows your current directory

vi : a editor

cat : shows content of a file on the Terminal

nano : a editor

cp : copies content

Above given were some commands of many. Anyone can google for Ubuntu commands which comes handy when using Ubuntu and eases the life on Ubuntu.

This was nothing but a introduction for Ubuntu. I will definitely go into the details in my coming posts. There are various things lined up, various knowledge is lined up for sharing, e.g., detailed Ubuntu, detailed Git, ruby a programming language. As more posts will come I will go more and more technical.

Till the next time

Keep learning, keep sharing..~~!!

Why Git?

Hello, and welcome again. I will continue from where I left. Remember what I said in my previous blog? --Keep learning and keep sharing!!--

If you haven't read it yet, here it is :"My First Blog" (advertisement may come; skip if you want to)

My blogs will be all about sharing what I learn and my experience. Post by post the blogs will become more technical.

Before proceeding further answer this question: Why is it important to share the knowledge?

What I learnt this week was totally new to me but was totally exciting- "Git".

Git is a software used for software development. Create a repository in the cloud and upload your locally created work. The uploading process is called push. Every time you push it gets saved with a new head so that you can download your previous works. Suppose you push something and you have been updating it for the past 10 weeks, you can still download your work what you updated after your update of 6th week because Git saves your every push with a new head or version and hence, Git is called a Version Control System. The downloading process is called pull.

Git makes it easier for a team with distant members to work on a single project. Each member can push their work on the cloud and pull other's work from the cloud. It is decentralized and hence, it is a Distributed Revision Control system. 

So, Git is a very essential software for a team in software development. This was more like an introduction, details will be in the next post. Till then, keep learning, keep sharing because learning and sharing both are important. One learns because someone else shares. What if scientists stop sharing? What if Newton, Franklin, Einstein and others hadn't shared their inventions and discoveries?

Keep Learning, Keep Sharing..~~!!
