The acronym for Vim is Vi IMproved. Written by Bram Moolenaar, it is a free and open-source text editor. It was first released for UNIX variants in 1991, and its primary purpose was to develop the Vi editor, which was released back in 1976.

\n

Vim is Vi's newest and most popular reincarnation that supports both text and graphical interfaces and is supported on any known platform.

\n

The issue with learning Vim is not that it's challenging to do. It's that you have to continue to do it. This guide aims to break the loop so that for the last time, you can learn it.

\n

The purpose of this tutorial is to take you through every step of progress from understanding the philosophy of Vim. In short, in a way that sticks with you for a lifetime, we're going to master Vim.

\n

Let's start off!

\n

What is Vim?

\n

Vim is a text editor for Unix that comes with Linux, BSD, and macOS. It is known to be fast and powerful, partly because it is a small program that can run in a terminal (although it has a graphical interface). It is mainly because it can be managed entirely without menus or a mouse with a keyboard.

\n

For the following five reasons, I feel people should use Vim:

\n
    \n
  1. It's omnipresent. You don't have to think about learning about several boxes with a new editor.
    2. \n
  2. It is highly scalable. You can use it only to edit configuration files or become your entire forum for writing.
    3. \n
  3. It has a shallow memory footprint.
    4. \n
  4. It's command-centered. With a few commands, you can perform complex text-related tasks.
    5. \n
  5. It is highly configurable and uses simple text files to store its settings.
    6. \n
\n

Why Use Vim?

\n

In all POSIX systems, Vim is the default fallback editor. Vim is sure to be open, whether you have just installed the operating system, or you have booted into a minimal system repair environment, or you are unable to access any other editor. While you can switch out other tiny editors on your systems, such as GNU Nano or Jove, it's Vim that's all but guaranteed to be on every other system in the world.

\n

In short, I think competence with Vim should be considered the way you view competence with your native language, or simple maths, etc. In technology, so much begins with understanding your editor.

\n

Also, It is extremely customizable and you can adapt it to your way of coding and your way of doing things.\nTo give you a taste of vim , below are a few commands frequently used to code at lightning speed:

\n\n

The list goes on and on...

\n

Basically we have standard keybindings like d for delete, c for change, f for find etc. and we can pair them with numbers to repeat that action n number of times. Moreover doubling a command like so yy makes the command operate on the entire line.

\n

So to sum up,

\n
\n

Vim is for programmers who want to raise their game. In the hands of an expert, It shreds text at the speed of thought.

\n
\n

How to use Vim

\n

Well, there is a learning curve, but it's worth it. Although this steep curve is exaggerated in the online world and the quitting vim joke is getting very old (It's:q btw).

\n

Install Vim sudo apt-get vim or pacman -S vim for Linux user and type vim <filename> in your terminal. Press i to go to insert mode. Type some gibberish. Press :wq to save and quit . :q! to quit without saving.

\n

First of all, don't get disheartened when you see VIM for the first time, it's known to make a horrible first impression. We'll learn to customize it later in the blog.

\n

\"BadVim\"

\n

To get started, get your hands dirty on vimtutor . It's a 20-30 minute vim tutorial which teaches you all the basics. Just type vimtutor in your terminal (in a machine where you have vim installed) to open it.

\n

Try Vim Adventures. An interactive game that teaches you vim skills in a step by step manner and lets you unlock new abilities after you've proved your worth with the previous ones.

\n

Just get started with it . Learn as you go . You can always refer to the Vim CheatSheet to get better. Practice makes a man perfect. Watch screencasts if that's helpful (was helpful to me).

\n

How do I configure my Vim ?

\n

The best way to configure your Vim is through .vimrc file, which is hidden inside your home directory. Open a terminal and type vim ~/.vimrc to open your vimrc file using vim. Cool huh? Using vim to configure vim ..no? Nevermind!\nHere you can define your keybindings, set themes, install plugins etc.

\n

Here is an example of a custom keybinding\nmap <C-n> :NERDTreeToggle<CR>\nYou can check out this article on keybindings and how to use them.

\n

The easiest way to download and manage plugins for vim is by using a plugin manager. There are quite a few vim-pathogen , Vundle.vim , Vim-plug etc.\nVim-plug being my favourite. Installations and usage for each plugin manager can be found in their respective repositories.

\n

I personally like to call all my plugins in a separate file and link that file to my vimrc. Paste this line in your vimrc at the top if you want to do the same source ~/.vim/plugin/plugins.vim\nIn your plugins.vim file you can install different plugins like this:-

\n
call plug#begin('~/.vim/plugged')\n\nPlug 'scrooloose/nerdtree'\nPlug 'moll/vim-node'\nPlug 'yegappan/mru'\n\ncall plug#end()
\n

The first and last lines are for vim-plug to know what plugins are to be installed. The lines beginning with Plug is to install that particular plugin.

\n

Now just reload .vimrc (or quit vim and re-enter) and :PlugInstall to install plugins.

\n

What are some good plugins for Vim?

\n

Glad you asked because Vim is no fun without plugins made by the awesome open source community.\nHere are some good plugins you should definitely install. Just search these on GitHub in case you wanna know more about them or their usage.

\n\n

Pheww!!..\nSo you see there's a plugin for anything and everything. These plugins are more than enough to make vim a full-blown IDE.

\n

Summing up!!

\n

VIM makes you write code at the speed of thoughts. Just get started, and the rest will follow. Steal your friend's vimrc or find one on the internet (there are tons of them) if you don't want to make one of your own.

\n

If you want to slowly blend in into the world of vim then use some vim plugin for your text editor. All popular text editors have a vim plugin ( Here's one for VsCode )\nHere you go, best of both worlds! When you're comfortable enough, go for that complete switch.

\n

\"vscodevim\"

\n

Here's how my vim setup looks.

\n

\"Vim\"

\n

Now go give it a try. I wish you luck!!

Generally, MIM attacks are breaking to believe the traditional encryption technologies and targeting the intermediate nodes between the sender and receiver.

\n

What is a MIM attack?

\n

MIM stands for man-in-the-middle. In the World of Cybersecurity, a man-in-the-middle attack (MIM) is an attack where the attacker breaks into the middle of the network pathway silently such that the sender and receiver are not able to intercept and they believe they are directly communicating with each other. One such example of a MIM attack is active eavesdropping. In this example, an attacker can be sitting with a piece of software somewhere in the network path and capturing all the relevant network traffic for later analysis. The attacker can intercept all relevant messages passing between the two victims and by smartly monitor and alter old ones or inject new ones. It can become complicated and arise problems for the organization.

\n

Does the question arise how about using SSL and Virtual Private Networks?

\n

SSL and Virtual Private Networks do not always protect messages as they travel across intermediary pathways. So, that where virtual dispersive networking comes into the picture.

\n

VDN follows the approaches or methods of traditional military radio spread spectrum security. Radios rotate through the frequencies randomly, and communications are divided or split into multiple pieces (or streams). So now, only one receiving radios are programmed to reassemble these pieces into their original form.\nVDN divides the original message into some multiple parts, and it will encrypt each component separately and routes them over many servers, computers, and even mobile phones. The data also move out dynamically to optimum paths — both randomizing the paths the messages take while simultaneously taking into the server congestion or other network issues.\nWhen it comes to the role of Hackers, they are left scrambling to find out data parts as they go through like data centers, Cloud, Internet, and so on.

\n

Why Virtual Dispersive Networking?

\n
    \n
  1. Unparalleled Security: Dispersing the data over multiple different paths, eliminates the Man-in-the-Middle threat. Hackers can only obtain a small chunk of the original data on any given pathway, rendering any data obtained meaningless and nearly impossible to decrypt.
    2. \n
  2. Network Resilience: Suppose a connection is lost on any of the several pathways due to network failure,\ndata packets are then rerouted to an already existing path, or an additional path is established which leads us resulting in negligible network downtime.
    3. \n
  3. Speed / Performance: Since the data-flow is from multiple independent paths using unique methods, it increases available bandwidth and optimizes data flow on individual pathways. Therefore, speed and performance are improved.
    4. \n
\n

Conclusion

\n

Today, Dispersive Technologies' business is largely government-centric, with initial forays into commercial industries with high-value targets like banks and utilities. There are many opportunities for Dispersive technology in the cloud computing world. The cloud can host the redirects at the center of their methodology without much of a stretch. However, cloud conditions can use Dispersive to set up secure communications between clouds or between on-premise information. These hybrid cloud situations regularly rely on VPNs, which will, in general, be flaky and moderate. Dispersive Technologies have become replacement of VPNs, thereby improving the security, performance, and manageability of hybrid clouds as well as virtual private clouds.

\n

As with any industry, change can be frightening (especially when sensitive data is part of the equation), but if the organization is aware of the new developments, they can begin implementing some of these security technologies into their existing IT infrastructure and enjoy some peace of mind without worrying about future threats.

React context API, In this article you will explore what is Context API, what is react context API and how to use it in your React project. The Context API is a React structure that enables you to exchange unique details and assists in solving prop-drilling from all levels of your application.

\n

What is Context API?

\n

The React Context API is a way for a React app to effectively produce global variables that can be passed around. This is the alternative to \"prop drilling\" or moving props from grandparent to child to parent, and so on. Context is also touted as an easier, lighter approach to state management using Redux.

\n

Talking about the Context APIs, they’re a (kind of) new feature added in version 16.3 of React that allows one to share state across the entire app (or part of it) lightly and with ease.

\n

React context API: How it works?

\n

React.createContext() is all you need. It returns a consumer and a provider. Provider is a component that as it's names suggests provides the state to its children. It will hold the \"store\" and be the parent of all the components that might need that store. Apart from the react context Provider, Consumer as it so happens is a component that consumes and uses the state. More information can be found on React's documentation page

\n

Context API will replace redux?

\n

No. Well, not entirely.

\n

Redux is great and came perfectly to answer the need for state management. Actually, it answered this need so well that it came to be known that you can't be a \"true\" React developer if you don't know your way around Redux.\nHowever, Redux has its disadvantages, and that's why it's important to know what Context API gives us that Redux doesn't:

\n\n

Important Note

\n

Redux is just a concept. If you are comfortable with using reducers and actions and don't find hindering than you may also create reducers and actions that wrap Context API as the store as Redux's author Dan Abramov explained in his medium article about whether Redux is always required

\n

How to use Context API?

\n

You might think to yourself: \"Well, I'm convinced. How do I implement Context API in react for my app?\" First, make sure you need it. Sometimes people use shared state across nested components instead of just passing it as props. And if you do need it you should follow these very few steps:

\n
    \n
  1. Create a folder under your app root named contexts (not required. just a convention)
    2. \n
  2. Create a file named <your context name>Context.js, e.g. userContext.js
    3. \n
  3. import and create a context like so:
    4. \n
\n
import React, { createContext } from "react";\nconst UserContext = createContext();
\n
    \n
  1. Create a component that will wrap the provider named Provider e.g. UserProvider
    \nExample using React Hooks:
    2. \n
\n
const UserProvider = ({ children }) => {\n  const [name, setName] = useState("John Doe");\n  const [age, setAge] = useState(1);\n  const happyBirthday = () => setAge(age + 1);\n  return (\n    <UserContext.Provider value={{ name, age, happyBirthday }}>\n      {children}\n    </UserContext.Provider>\n  );\n};
\n
    \n
  1. Create a higher order component to consume the context named: with e.g. withUser
    \nExample using React Hooks:
    2. \n
\n
const withUser = (Child) => (props) => (\n  <UserContext.Consumer>\n    {(context) => <Child {...props} {...context} />}\n    {/* Another option is:  {context => <Child {...props} context={context}/>}*/}\n  </UserContext.Consumer>\n);
\n

The difference between the two options above is if you want the context to be a single nested property by this name, to explode it to its properties (which in my opinion is more convenient).

\n
    \n
  1. Finally export them
    2. \n
\n
export { UserProvider, withUser };
\n
    \n
  1. And use them however you like
    \nFor example:
    2. \n
\n
ReactDOM.render(\n  <UserProvider>\n    <App />\n  </UserProvider>,\n  document.getElementById("root")\n);
\n
export default withUser(LoginForm);
\n

You'll also be able to notice I used the new \"Hooks\" feature that is shipped with React since version 16.8 to make it even neater and easier to create contexts.

\n

Final piece of advice

\n

I mentioned how people overuse Redux, and it also applies to Context API. Use it only when you need to share state between lot's of components with a lot of nesting.\nMost of the time, the data you have in one component will only be relevant to its children, so passing it in props is more indicative and nicer.

What is 'this' in Javascript

\n

The this keyword is, without doubt one of the most difficult Javascript concepts to understand. However, understanding it is key to being a great developer because it is an extremely common part of Javascript code.\nIn simple terms, this refers to the object it belongs to. It can also be defined as a property of an execution context, which is always a reference to an object when not in strict mode. It is worthy to note that the 'this' keyword finds usage mostly in the context of object oriented programming. With that in mind, the 'this' keyword will refer to the object to which it belongs; This is true most of the times. Let us use an example to explain this better.

\n
let bellBoy = {\n  firstName: "Andrew",\n  lastName: "Mike",\n  gender: "Male",\n  age: 18,\n  greet: function () {\n    return (\n      "Hi! I am " +\n      this.firstName +\n      " " +\n      this.lastName +\n      ", a bell boy and I am at your service"\n    )\n  },\n}\nconsole.log(bellBoy.greet())
\n

In the example above, there exists a bellBoy Object which consists of four properties and a greet method. When the greet method of the bellBoy object is called, can you figure out what will be returned? The console.log will print the following string: Hi! I am Andrew Mike, a bell boy, and I am at your service.

\n

How did 'this.firstName' and 'this.lastName' translate to Andrew and Mike respectively? Well, to answer that, let us go back to the definition of the 'this' keyword. It was said earlier, that it refers to the object it belongs to. So, in the example above, the 'this' keyword refers to the bellBoy object, which is the owner of the greet() method. The dot(.) operator can be used to access members of the object as defined by the 'this' keyword. In the current console.log(), we are using the dot(.) operator to call or access the greet() method. In the same vein, we can use the dot(.) operator to access the properties method of the bellBoy object like the gender and the age.

\n

Contexts in which the 'this' keyword can be used

\n

The definition of this as the property of an execution context is much more accurate because depending on how it is called at runtime, 'this' can refer to many things. Let's dive deeper.

\n\n

More contexts exist in which the value of the 'this' keyword differs.

\n\n

And many more. For a full description of this keyword, check out these links:

\n\n

It might be a good idea to run the snippets of code to be sure that you understand how they work. To do this, use the free webmaker or the codeplay code playgrounds.

You can have data without information, but you cannot have information without data

\n
\n

~Daniel Keys Moran

\n

Who runs the World?

\n

Simple Question! Isn't it?

\n

Answer- Of course, we humans, \"People\" run the world.

\n

The correct answer would be data. Precisely, the information we gain from data. In this digital world, the one most common thing we all do is\n\"We all generate data\". Whenever we do something digitally, we generate data. Listening to a song, watching a movie, playing a game, chatting with friends, reading a comic blah blah blah everything generates data.

\n

Can you imagine?

\n

7.8 Billion people currently live on Earth, and almost 4.57 Billion people are active internet users, encompassing 59 percent of the global population.\nThis is the sixth edition of DOMO's report, and according to their research:\n** \"Over 2.5 quintillion bytes of data are created every single day, and it's only going to grow from there. By 2020, it's estimated that 1.7MB of data will be created every second for every person on earth.\"**\nAs 1 Exabyte = 1 quintillion bytes, so 2.5 Exabytes ( 2.5 * 10¹⁸ bytes) of data is generated per day.

\n

\"b\"

\n

Big companies like Google, Amazon, Netflix, Instagram, Facebook, Twitter, and many more are generating tons of data daily.\nInformation is taken from here.

\n

Google: 40,000 Google Web Searches Per Second

\n

More than 3.7 billion humans now have regular access to and use the internet. That results in about 40,000 web searches per second — on Google alone.

\n

Facebook: 500 Terabytes Per Day

\n

In 2012, Facebook's system was generating 2.5 billion pieces of content and more than 500 terabytes of data per day.

\n

Twitter: 12 Terabytes Per Day

\n

One wouldn't think that 140-character messages comprise large stores of data, but it turns out that the Twitter community generates more than 12 terabytes of data per day.

\n

General Stats: Per Minute Ratings

\n

Here are some of the per-minute ratings for various social networks:

\n

Snapchat: Over 527,760 photos shared by users

\n

LinkedIn: Over 120 professionals join the network

\n

YouTube: 4,146,600 videos watched

\n

Twitter: 456,000 tweets sent or created

\n

Instagram: 46,740 photos uploaded

\n

Netflix: 69,444 hours of video watched

\n

Giphy: 694,444 GIFs served

\n

Tumblr: 74,220 posts published

\n

Skype: 154,200 calls made by users

\n

These companies use this data to uncover the hidden patterns, correlations, and also to give insights to make proper business decisions. They analyze data for Customer Acquisition and Retention and try to personalize their products for their customers to establish a solid customer base.

\n

As of August 2020, desktop hard disk drives typically had a capacity of 1 to 8 terabytes, with the largest-capacity drives reaching 20 terabytes (single-disk drives, \"dual\" drives are available up to 24 TB).

\n

Another Question- How they do it?

\n

If the capacity of storage devices is much lesser than the data generated per day by such companies, how they manage it. How they process such a large amount of data without storing it anywhere? How Google search gives results in just a few seconds after processing the data stored for years? Can we store data in a storage device whose volume exceeds the capacity of the hardware?

\n

Problem:- Big Data

\n

All these problems combined are called Big Data. Below are some subparts of the Big Data problem-

\n
    \n
  1. Firstly, the volume of data is too large. Even if we build storage devices of huge capacity, we can't cope up with the increasing data per day.
    2. \n
  2. Secondly, the cost of manufacturing. Even if we manufacture large size storage, it is not possible to afford their manufacturing prices even for high-profit organizations. So, What are the solutions for low- budget companies? How can they manage data?
    3. \n
  3. Thirdly, Velocity of data transfer(I/O Operations). If we ignore the above limitations, the next problem posed is the time taken by Processing units to process this data. Because of the huge volume of data stored in large-capacity storage devices, data transfer is time-consuming.
    4. \n
\n

\"c\"

\n

Solution:-

\n

Big Data can be taken as technology or field that treats ways to analyze, systematically extract information from, or otherwise deal with data sets that are too large or complex to be dealt with by traditional data processing.\nOne of the concepts that solve the above problem is Distributed Storage.

\n

Distributed Storage Cluster-

\n

\"d\"

\n

Distributed storage is a method that provides huge storage(even exceeding from physical storage) shared by multiple systems. These systems or the servers are connected following horizontal scaling. This multiple commodity server hardware is comparatively cheap than optimized servers with large storage(Hard Disk). Each virtual machine contributes directory to a centralized system and thereby shares its storage. The team of master and slave nodes working together for one purpose called a cluster.

\n

One of the Topologies or the architecture used for implementing a Distributed storage system is Master-slave architecture.\nMaster-slave architecture- Master-slave is a model of asymmetric communication or control where one device(the \"master\") connected to one or more other devices(the \"slaves\") are connected using a protocol(Network), where the slave nodes/devices can contribute a part/whole of their storage devices to the master node, like this centralized master node can store data exceeding its local storage limit.

\n

The slave nodes can be commodity hardware/devices that need not be expensive and high functioning.\nAs the data is split and stored in(and loaded from) other devices/nodes, the I/O operations (data transfer) can be performed parallelly on all the devices. Thus, reducing the time consumption by a large factor.

\n

Hence, distributed storage solves all the problems- Volume, Cost, and Velocity.

Distributed storage is just a concept, and some companies have launched different software or products that work on this concept which solve the problem of Big Data. One such company is APACHE and the software APACHE HADOOP.\nThe Apache Hadoop software is a collection of libraries that provides facility to create clusters/network of systems following the distributed system. It can be used in processing the huge data distributes in thousands of machines, each offering local computation and storage.

Social engineering attacks have become a common occurrence against enterprises over the years. In fact, it has grown increasingly sophisticated. 

\n

Needless-to-say there is no ‘stop sign’ for cybercrimes any time soon. Instead, hackers have been coming up with more creative methods to deceive employees and people into sharing sensitive credentials.

\n

It is high time that companies conduct proper research and utilize the right tools to keep ahead of the fraudsters.

\n

This infographic will cover what social engineering is and the best practices to avoid becoming a victim of the most common social engineering attacks.

\n

What is Social Engineering 

\n

Social engineering is a cyberattack where criminals psychologically manipulate unsuspecting users into making security mistakes and giving up their confidential information. 

\n

Social engineering involves the criminal using human emotions like fear, curiosity, greed, anger, etc. to trick victims into clicking malicious links or physical tailgating attacks. 

\n

Social engineering attackers have one of two goals: 

\n\n

Common Social Engineering Attack Techniques

\n

Here is a quick overview of the most common social engineering scams used against modern enterprises and individuals.

\n

Phishing

\n

Phishing is the most common and widely successful form of social engineering attack. The fraudster uses trickery and deceit via email, chat, web ad, or website to persuade a person or organization to expose their PII and other valuables. 

\n

For example, the fraudster might pretend to represent a bank, a government organization, or a major corporation trusted by the naive victim. The source can be an email asking the email recipients to click on a link to log in to their accounts. They are then redirected to a fake website appearing to be legitimate, and that's where the attack takes place.

\n

\"passwords

\n

Spear Phishing

\n

Spear Phishing is another form of social engineering where the fraudster does some background research on the victim's personal and professional life to establish the right pretext.

\n

For example, the fraudster might reveal to the victim that they are planning a surprise birthday for a friend and are seeking help to pull it off.

\n

Baiting

\n

Baiting is when the fraudster uses greed or curiosity to trap the victim with false promises and trick them into handing their login credentials.

\n

For example, the fraudster may leave a malware-infected, authentic-looking flash drive (or bait) in the least suspicious area like the bathroom or elevator of a company. The bait will also have enticing labels like a payroll list or appraisal list that will be tempting enough to insert on a computer. 

\n

Tailgating

\n

Tailgating happens when someone without proper authentication enters into a restricted area by physically bypassing the security measures in place.

\n

For example, the attacker can strike up conversations with an employee in the lobby or the parking lot and use the familiarity to enter the office premises and get past the front desk.

\n

Scareware

\n

Scareware is a malware tactic where the fraudster perceives a threat to deceive users into visiting malware-infected sites and buying malicious software.

\n

Examples include PC Health Check Programs and Antivirus Updaters that scare victims into buying diagnostic and repair services they do not need. 

\n

Warning Signs of Social Engineering Attacks

\n

One of the best ways to protect against social engineering is to understand the warning signs and steer clear of attacks. A few of the warning signs include:

\n\n

Best Practices to Prevent Social Engineering Attacks 

\n

Be careful of what you share. And no, you don't need to be paranoid about these attacks. Preventing them is possible. The following are a few ways that help.
